Holding a cell phone against your ear or stalling it in your pocket may be hazardous to your health. This paraphrases a warning that cell phone; manufacturers include in the small print that is often tossed aside when a new phone is purchased.Apple, for example, doesn't want iP hones to come closer to you than 1.5 centimeters; Research In Motion, Blackberry's manufacturer, recommends 2.5 centimeters. If health issues arise from cell phone use, the implications are huge.Voice calls - Americans chat on cell phones 2.26 trillion minutes annually - generate $109 billion for the wireless carriers. Devra Davis, an epidemiologist who has worked for the University of Pittsburgh, has published a book about cell phone radiation, "Disconnect." The book surveys scientific research and concludes the question is not settled. Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population. "Most cancers have multiple causes," she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer. Children are more vulnerable to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid. No studies have yet been completed on cell phone radiation and children, she says. Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiofrequency radiation had damaged DNA in their brains. Ms. Davis recommends using wired headsets or the phone's speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen. In which column can we most probably read this passage?

Whenever someone begins to talk to me about how horrible it is to eat meat and suggests that a nice piece of tofu would be just as good, I just smile and show them those nice pointy teeth we all have in the corners of our mouths. They are called canines , and they are there only for the purpose of eating meat. When it comes to satisfying this kind of desire, soy food can never match a well-prepared tri-tip (also know as triangle beef steak ). Just the thought of the beef, burning on the grill with the smell of wood smoke gets the mouth watering and brings back memories of summer barbecues. When the knife cuts through the tri- tip, exposing the red meat bursting with juices, it's more than just cooking. It's a cultural event, showing we are at the top of the food chain, like no other food can. Nutritionally speaking, the tri-tip is one of the better cuts of beef. It is lower in fat than many other cuts, and the proteins you get from eating meat are more complete than those that come from vegetables, making meat a better choice for building and keeping up your muscle tissue healthy. According to the National Center for Biotechnology Information, one thing to be aware of with soy products in general is that while they are high in iron, a necessary mineral for the body, they also contain something that blocks the body's absorption of iron. We can cook them in various ways to make them tasty. Anyway, the tri-tip goes a lot better with ice-cold beer than a large piece of bean-curd cheese would, no matter how you cook it. I guess I should say at least e good thing about tofu. If you cook it just right, you can make it taste a little like the tri-tip, but only a little. What's the author's attitude towards eating meat?

From the very beginning, Martin felt that he was bound up with(......)his lovely little patient. One day, following some tests , Betty gave the doctor a big hug . A few months later the doctor removed not only the tumour , but also the entire lower left side of Betty's gum and jawbone. Because Betty was so young, Martin was hopeful that her jawbone might regenerate. Within three months, Betty's tumour grew as large as an orange, changing the natural appearance of the left side of her small, delicate ( =" thin;" not strong)face. Soon she couldn't even close her mouth, and as her eating problems worsened, Betty 's weight dropped from 20 kilos to 15. Martin knew from experience that it might invade the brain. The only other possibility was thorough radiation therapy . Night after night, Betty's father gave her injection, but the tumour remained as big as ever. Then one evening. Morgan noticed that the tumour had begun to change. It was actually becoming smaller! For two months her tumour appeared to be going away for ever.

Comets are parts of our solar system. Like the planets, they go around the sun. But comets are not made of solid rocks like planets. A comet is a ball of dust, stones, and ice. Many people call comets dirty snowballs. The "snowball" may be only a few miles across. But when the sun heats the "snowball," much of it is changed to gases. The gases spread out and form the comet's head, which may be thousands of miles across. A comet moves fast in its trip around the sun. But when we see it, the comet does not seem to move. That's because it is so far away. The moon moves fast, but when you look at it, you can't see any motion . That's because the moon is far away. Each year astronomers discover new comets. Some of them are seen only once. They make one trip around the sun and then go away out into space. The sun's gravity cannot hold them. Other comets, like Halley, keep returning. They have been captured by the sun. Halley's earliest visit was probably 3,000 years ago. It may keep returning for another 3,000 years. But every time a comet goes around the sun, the comet loses part of itself. Gases and dust are pulled out of the comet. That's why Halley is now dimmer than it used to be. Next time it visits us, in 2062, it may be even dimmer. Each visit it may get dimmer and dimmer, until it finally disappears. How does the writer help the reader understand what a comet looks like?

I Online shopping started not so long ago. Tim Berners-Lee invented the World Wide Web in 1990. The first online bank opened in 1994. In 1995, Amazon started operating and is not one of the largest online shopping malls. Then in 1996, eBay started its online shopping site. By sitting at home you can now buy anything from knives to cars. The worry you may have about traveling and parking can be avoided while you shop online. With online shopping, you need not worry about the weather. Online shops have no holidays, closing times or any other problem. You can shop 24 hours a day, 7 days a week and 365 days a year. Some online shops also keep customers' opinions about each product, so you can easily find out what other customers think about the product before buying it. When you go for real-world shopping, you can actually touch and feel it, but in online shopping you can only see the pictures. Also if you are shopping online, you have to be careful with your credit cards. The first step in online shopping is to search for what you want to buy. Once you find the required product, put it in a "shopping cart" and continue shopping. After you have got enough in your "shopping cart", check out the product. You can add or take out the products in your shopping cart. The next step is to log in using a username and a password. Enter the address where you want the product to be sent. Some sites even ask for your email, phone numbers, etc. Then wait for the confirmation of your order. You can also cancel the order if needed. Online shopping is a different experience and you can make shopping online easy when you get used to it. I When shopping online, you can _

China started late in network technologies and has lagged behind for years. With the rapid development of wireless technologies, the concept of the Fifth Generation (5G) mobile communication system started to emerge . Although the development of 5G network technology in the international community is still in the research stage, a number of foreign countries and organizations are working on it. In order to catch up with the pace of the times, China also needs to have its own place in such a competitive environment. Compared with 2G, 3G and 4G, 5G is not independent and brand-new. It is a combination and further development of present mobile communication technology. Besides the speed upgrade, 5G will also meet the requirements of large bandwidth, super high capacity, super dense site, super high reliability and whenever and wherever possible assess. There are some rapid changes in China's telecom space. With the 3G network now widely used, and 4G just around the corner, China is now preparing to enter the 5G era. China has started research and development on the 5G network, and plan to launch the network testing by around 2020. It's expected that a unified standard will be adopted globally with the 5G technology. "Under a same standard, different enterprises can be connected, and form a competition environment. Therefore, we can guarantee that enterprises can gain reasonable profits, and at the same time provide faster, better, more convenient and cheaper services to consumers." Wu Ku, Director of Dept. of Science & Tech., MIIT said. Wu Hequan from Chinese academy of engineering said, "5G will make it possible to connect one million devices to the so-called Internet of Things within one square meter. In the future, it will also be available on high-speed trains moving as fast as 500 kilometers per hour. In the area of the Internet of Vehicles, it can be used in unmanned vehicles, assisted driving and the management of smart cities." Wu believes China's future Internet will be faster, more intelligent and more reliable. Chinese government pays more attention to the development of 5G and adopts a more open attitude. With the joint effort of the industry, China will play an increasing important role in the global 5G development. What's Wu's attitude towards the 5G network technology?

Breakfast is the most important meal of the day. It is also the most neglect . Common reasons for not eating breakfast include having no time, not feeling hungry, traditional dislike and dieting. Breakfast simply means "break the fast''. Your body spends at least 6 to 12 hours each night in a fasting state. In the morning your body needs energy for the day's work ahead. A good breakfast should provide 1/3 of your total calorie needs for the day. On average, we eat 400 less calories for breakfast than for dinner. If breakfast doesn't appeal to you in the morning, try eating a lighter dinner earlier in the evening or save half of your dinner for breakfast in the morning. If you still aren't hungry in the morning, start with something small like juice or toast or have a nutritious mid-morning snack later when you are hungry. So, you say you are on a diet. Some people fear that eating breakfast will make them hungrier during the day and they will eat more. It is true that eating breakfast is likely to make you feel hungry throughout the day. That is because your body is working correctly. Although you may feel as if you are eating more all day long, in reality you are probably not. Not eating breakfast can also cause you overeat, since a fall in blood sugar often makes you feel very hungry later. To make matters worse, since your body is in a slow state, it will not be able to burn those extra calories very efficiently . If you feed your body healthy snacks and meals throughout the day, you are less likely to become hungry and stuff yourself as soon as you begin to eat. Since breakfast is the first and most important meal of the day, choosing the right food is important. The best breakfast foods are fruits, juice, lean meat and grain products such as bread, rice, noodles and cereals. Not eating breakfast will _ .

Have you heard about the periodic table lately? Well, there's some big news about this special table, but first, remember that the periodic table is used for all the elements , or things that make up our world. Elements are all around us. Iron is one of the most common elements found on the earth. You probably know the element oxygen , which is the element that we breathe in all the time. And elements can combine to make new things like H2O. This is hydrogen and oxygen put together, also known as water! Learning about these things helps us better understand the world we live in. But have you ever noticed something missing in the periodic table? There were already 114 elements. But the seventh row of the table was not finished, until now! In December, scientists from the IUPAC found the four elements that were missing. They are elements 113, 115, 117 and 118. "To scientists, this is of greater value than an Olympic gold medal," Ryoji Noyori, a Nobel honored chemist said. The new elements are heavy metals and were made in lab. These kinds of elements can't be found in nature. Scientists are still looking for ways to use these elements, and other elements in the eighth row in our daily lives. Scientists have been working on this for 10 years, but the work is not done. Now they will prepare to look for "element 119 and _ ". But for now, be mindful when you read your science books because the periodic table might be outdated . Which of the following about the new elements is NOT true?

The koala is possibly one of the best known Australian animals, and is found in four states: Queensland, New South Wales, Victoria and South Australia. The word "koala" comes from an Australian aboriginal word meaning "no drink". Sometimes people call them "koala bears" but koala is not a bear. It belongs to a special group of Australian mammals, called marsupial . Female marsupials have a _ where the baby animals live after they are born. Koalas have soft, thick, grey or brown fur on their backs. The fur on the stomach is white. Koala that live in the south have thicker fur than those in the north because of the cold winters, whereas the koalas in the northern part of the country live in warm to hot weather most of the year so have thinner fur. A koala has a large hairless nose and round ears. Koalas don't have tails. Adult koalas measure between 7 and 14 kilograms. Koalas spend nearly all their time in the trees using their sharp, curved claws and long toes to climb about and to hold on to the tree branches. They sleep most of the day, and feed and move from tree to tree mainly at night. The reason koala sleep for much of the day is because their food eucalyptus leaves are very tough so they use a lot of energy to digest. Sleeping saves energy. Eucalyptus leaves are poisonous to almost every other animal. Koalas rarely drink water; they get water from the leaves they eat. Each koala has a home range made up of several trees that they visit regularly. They normally do not visit another koala's home trees except that a male is looking for a female to mate with. Which of the following statements is NOT true about the name "koala bear"?

Air pollution, such as haze, has become a serious problem around the world. Besides wearing a mask, what else can we do to protect ourselves from the dirty air? Scientists have developed a new inhaler that can reduce the effect air pollution has on people. It could help millions of people who are suffering from air pollution,the Guardianreports. This inhaler is developed by German company Bitop and contains a molecule named Ectoine. The molecule creates a layer that protects lungs from polluted air. It's reported that the inhaler will be affordable to most people when it comes to the market. Air pollution kills more than three million people a year worldwide and leads to health problems like lung and heart disease and strokes, according to a 2016 research project in the journalNature. It is also linked to brain disease, mental illness and diabetes . Andreas Bilstein at Bitop believed that the inhaler could be useful around the world, because air pollution is not just a European problem: "Especially in Asia - China in particular - the demand for such a product is even higher." Many Chinese cities have been suffering from haze. According to World Health Organization, two of the 10 most polluted cities in the world in 2015 were in China. About 800,000 deaths that are linked to air pollution take place in the country every year. However, such inhalers should never be an excuse for not trying to stop air pollution, said Professor Jean Krutmann at the Leibniz Research Institute for Environmental Medicine. "The best thing is that we have clean air and we don't need any prophylactic treatment," he said. Which is Professor Jean Krutmann's opinion?

It is common for older people to forget things. Now an American study has found that memory starts to fail when we are young adults. People younger than thirty years of age usually do not know that they are starting to forget information. But scientists from the University of Michigan say the loss of memory has usually already started. Researchers say people do not observe this slow reduction in mental ability until the loss affects their everyday activities. Denise Park led the new study. She directs the Centre for Aging and Cognition at the Institute for Social Research at the University of Michigan. Her team studied more than 350 men and women between the ages of twenty and ninety years. The study identified people in their middle twenties with memory problems. She says young adults do not know they are forgetting things because their brains have more information than they need. But she says that people in their twenties and thirties are losing memory at the same rate as people in their sixties and seventies. Ms. Park says people between the ages of sixty and seventy may note the decrease in their mental abilities. They begin to observe that they are having more trouble remembering and learning new information. The study found that older adults are more likely to remember false information as being true. For example, they remembered false medical claims as being true. Younger people remembered hearing the information. But they were more likely to remember that it was false. Ms. Park is now using modern imaging equipment to study what happens in the brains of people of different ages. She is studying what parts of the brain older adults use for different activities compared to younger adults. Ms. Park says mental performance is a direct result of brain activity and brain structure. She says keeping the brain active is important. She hopes future studies will identify ways to improve the operation of our aging minds. The passage is meant to _ .

For years experts have argued that poor households are consuming less nourishing food than the rest of the population. But a survey of some of the lowest earners in Britain shows the nutritional value of what they eat is little different to everyone else. In fact, the same deficiencies in diet were shared by all the population and the findings suggest that poor eating choices are far more widespread than previously suspected - affecting many wealthier families. These included low fruit and vegetable consumption, not eating enough oily fish and eating too much saturated fat and sugar. "This is a large and significant study and it shows we are all eating just as bad a diet as each other," said Tim Lang, professor of food policy at City University. The poorest families were eating only slightly more sugar and slightly less fruit and vegetables, according to the study of 3,728 respondents in the bottom of the population. Alison Tedstone, head of nutritional science at the Food Standard Agency, said: " Overall, people on low incomes have less than ideal diets, but their diets are only slightly worse than those of the rest of the population." The study also showed that low earners are choosing to eat unhealthily. Their food choices were not linked to their income, their access to shops or their cooking skills. The findings appear to contradict assumptions that the poor cannot afford healthier foods or are too far away from shops that sell them. The Low Income Nutrition and Diet Survey showed that like the rest of the population, the poor's daily fruit and vegetable intake on average is below the recommended five portions. Fewer than 10 per cent of respondents hit this target, while around 20 per cent ate less than a portion per day. More than three quarters (76 per cent) of men and 81 per cent of women did less than one 30-minute session of moderate or vigorous exercise per week. Some 45 per cent of men and 40 per cent of women were smokers. This compares with 28 per cent of men and 24 per cent of women in the general population. From the passage, we can learn _ .

In 2004,the World Health Organization,WHO,warned of a possible outbreak of another serious disease which may be even more deadly than SARS.The WHO believes that it is likely that bird flu will spread to human beings in the next few years.If it does,up to seven millions people could die from the disease. Diseases like bird flu are caused by viruses,that is,tiny things which change and be come more dangerous over time.When a new type of a common virus changes,it may be able to get past the body'S immune system.If that happens,humans are in great danger until a cure or treatment becomes available. There have always been viruses and people always get sick,of course,but as we saw with SARS,the situation is more difficult today.People travel more than ever before,which means that disease can spread quickly and across large areas----in fact the whole world. Scientists are already working on drugs that will prevent or limit the effect of a new virus,but the process takes time.It is just as important to make sure that countries,especially poor countries,are prepared to deal with the disease. New disease usually affect poor areas the most,so we must help develop health care in all countries. The possible title of this passage is

Surgical teams accidentally leave clamps, sponges and other tools inside about 1,500 patients nationwide each year. The mistakes largely result not from surgeon tiredness, but from the stress arising from emergencies or complications discovered on the operating table, the researchers reported. The study found that emergency operations are nine times more likely to lead to such mistakes, and operating-room complications requiring a change in procedure are four times more likely. It also happens more often to fat patients, simply because there is more room inside them to lose equipment, according to the study. Two-thirds of the mistakes happened even though the equipment was counted before and after the procedure, in keeping with the standard practice. Most lost objects were sponges, but also included were metal clamps and electrodes . In two cases, 11-inch retractors metal strips were forgotten inside patients. In another operation, four sponges were left inside someone. When there is significant bleeding and a sponge is placed in a patient, it can sometimes look indistinguishable from the tissue around it. The lost objects usually lay around the abdomen or hips but sometimes in the chest. They often caused tears or infections. Most patients needed additional surgery to remove the object. In other cases, patients even sensed nothing about the object, and it turned up in later surgery for other problems. To prevent such mistakes from happening, Loyola University Medical Center is becoming one of the first hospitals in the country to use sponges outfitted with bar codes. The new system was brought to Loyola through the efforts of the hospital's operating room nurses. Another effective way is to X-ray patients after surgery to reduce the likelihood of objects being left inside patients. What is the best title for the passage?

If you have ever been left wondering why your emails are riddled with grammatical errors, or why you can never quite find the right phrase, it may be because you are typing with both hands. Our vocabulary becomes richer and our writing style becomes more fluent when we type using just one hand, scientists have found. "Typing can be too fluent or too fast, and _ can actually weaken the writing process," said Srdan Medimorec, the lead author of the study conducted at the department of psychology at the University of Waterloo, Canada. "It seems that what we write is a product of the interaction between our thoughts and the tools we use to express them." Using text-analysis software, researchers asked 103 university students to write essays under different conditions, using one hand to type and using both hands to type. The software was used to analyze elements of the essays, such as range of vocabulary, sentence complexity and the cohesion of the writing. Researchers found that participants' vocabulary became more advanced when they typed with one hand rather than two. The research team said that by slowing our writing down, typing one-handed allows more time for an internal word search, resulting in a larger variety of words. In contrast, fast typists might just write the first word that comes to mind. However, it is important not to slow typing down too much. Those who typed essays one-handed in the current study slowed down to about the speed of handwriting. This is the first study to show that changing people's typing can make their writing get better. The researchers suggested that the speed of writing could affect writing quality regardless of the tools used, whether they are computers, or pen and paper, although further research would be required to prove that idea. Which is the best title of the passage?

The Horn of Plenty is one of the largest natural health food stores within the Greater Hamilton area. We are big supporters of buying locally and we are here to tell you why it is so important for your family, the community and the environment. The concept of buying locally is simple: buy food produced, grown, or raised as close to your home as possible. Not only will your food be fresher and tastier, but you are helping protect the environment and are supporting businesses within your community and reducing pollution. Better for the environment Sustainability and global warming are such hot topics at the moment, and many people want to do their bit to help support a healthier environment. Small action carried out by many people can make a big difference. Most materials in an average North American meal have traveled about 1,500 miles to get from farm to plate. To cut out a big part of this travel would greatly reduce not only pollution from transportation and refrigeration but also customers' expenses as well. Taste and nutritional content Locally-grown fruits and vegetables are usually sold within 24 hours of being harvested. Because they are picked at the height of ripeness and travel only a short distance to the market, their freshness, nutrition, and flavor are kept. Produce trucked in from far away may lose both taste and nutritional content. Community and home values When you buy direct from a farmer or buy locally-grown foods, you are engaged in a time-honored tradition between a grower and an eater. You also help keep dollars within your community. According to the author, when you buy locally-grown foods _ .

Giant pandas are now extremely rare. Their number is less than 1,000 in the wild. The hunting of pandas has been banned for many years, so this is not the problem. Destruction of its habitat, when areas are cleared for growing crops, is one of the main reasons for panda's decline . Another reason is that the bamboo on which they mainly feed, is dying back. The pandas find it difficult to move to new feeding areas. As the bamboo disappears, the pandas simply starve to death. Bamboo is a poor source of food, and pandas have to eat up 45kg of it every day, a process that takes them up to 16 hours. The process goes on day and night, with the pandas in a constant cycle of eating for eight hours and sleeping for four. They can eat other foods, but will rather starve than change their diet when bamboo is scarce. Giant pandas are very good climbers, and use this skill to escape from the enemy. The giant panda lives alone for most of its life, only coming together with another of its species for long enough to mate. A newborn panda baby is born hairless and blind, is about 15cm long and weighs only 100g. The baby will stay with its mother for about 18 months, until it is able to set up its own territory Chinese and American scientists are studying giant pandas and their habits in order to put in place a major conservation programme. Zoos around the world are taking part in panda breeding programmes. There is still hope that with human's help, the giant panda can survive in the wild. What can we learn from the text?

Speeding off in a stolen car, the thief thinks he has got a great catch.But he is in for an unwelcome surprise.The car is fitted with a remote immobilizer, and a radio signal from a control centre miles away will ensure that once the thief switches the engine off, he will not be able to start it again. The idea goes like this.A control box fitted to the car contains a mini-cellphone, a micro-processor and memory, and a GPS satellite positioning receiver.If the car is stolen, a coded cellphone signal will tell the control centre to block the vehicle's engine management system and prevent the engine being restarted. In the UK, a set of technical fixes is already making life harder for car thieves." ," says Martyn Randall, a security expert.He says it would only take him a few minutes to teach a person how to steal a car, using a bare minimum of tools.But only if the car is more than 10 years old. Modern cars are far tougher to steal, as their engine management computer won't allow them to start unless they receive a unique ID code sent out by the ignition key.In the UK, technologies like this have helped achieve a 31% drop in vehicle-related crime since 1997. But determined criminals are still managing to find other ways to steal cars, often by getting hold of the owner's keys.And key theft is responsible for 40% of the thefts of vehicles fitted with a tracking system. If the car travels 100 metres without the driver confirming their ID, the system will send a signal to an operations centre that it has been stolen.The hundred metres minimum avoids false alarms due to inaccuracies in the GPS signal. Staff at the centre will then contact the owner to confirm that the car really is missing, and keep police informed of the vehicle's movements via the car's GPS unit. The operations centre will first _ after receiving an alarm.

Invented in Turkey and patented by Nanopool, a German company, the spray-on liquid glass might become one of the most useful inventions in the field of nanotechnology. The product was tested at the Saarbrucken Institute for New Materials. It is worth mentioning that the invention is transparent and non-poisonous. The liquid glass can protect any type of surface from damages caused by water, UV radiation, dirt, heat, and bacterial infections. Besides, it is flexible and breathable, which means that the liquid glass can be applied on plants and seeds as well. Researchers found that the spray greatly increases the resistance of plants to bacteria-caused diseases. The trials also showed that the sprayed seeds grew faster. Depending on the type of surface that is to be covered, researchers can add water or ethanol to the spray. Scientists say that _ . The spray produces a coating that is just 100nm thick. Trials by food processing plants in Germany have concluded that foods covered with the glass can store longer than those stored in normal condition. According to Neil McClelland, UK project manager with Nanopool, due to its capabilities, the spray-on liquid glass can become one of the most useful inventions around the world, ending up being used by a lot of industries that will cover their products. At present, the invention is being used by a train company and a hotel chain in the UK, as well as a hamburger chain in Germany that are carrying out tests of the liquid glass for various uses. The spray-on liquid glass was also tested in a Lancashire hospital, where it showed "very promising" results, being used to cover medical equipment and bandages. The invention could be also used on clothing, because it cannot be seen by the naked eye, thus clothes could become stain resistant. Due to its unique characteristics, the liquid glass can be used to cover bathrooms, sinks and many other surfaces in the home. According to the researchers, the spay-on glass can last for a year. It is expected to hit the DIY stores across Britain at a price of 5 pounds. Which of the following about the liquid glass is NOTtrue?

In the near future, we may be using our eyes to operate our smartphones and tablets, even when it comes to playing popular games like Fruit Ninja. The GazeGroup has been developing eye-controlled computer technology for nearly 20 years. But those devices have been mainly designed to aid those with disabilities, and are very expensive. "After a while, we figured out that probably the best way is to go for a mass-market approach," says Gaze's Sune Alstrup Johansen, "where everybody would have this available." Johansen and some of his colleagues have formed a new company, The Eye Tribe, which is hoping to develop the technology on a mass commercial level. The technology works by sending an infrared light from the computing device toward the user's face. After measuring the user's eye movements, the technology is then able to easily know where a person's eyes are moving, allowing the eyes to control a cursor . A software can determine the location of the eyes and tell where the user is looking on the screen. It even knows which image he is looking at. There has been a gradual change toward hands-free technology in recent years, particularly in the gaming world. Following Nintendo's popular Wii system, Xbox released the Kinect device, which lets users control their Xbox and play certain games using only their hands, legs and voices. Since most smartphones and other mobile devices can't come standard with an infrared device, Johansen said a replaceable filter would be an inexpensive, convenient choice for most consumers. And even as companies like The Eye Tribe work to create a commercially practical product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for disabled users. "Then I can go to any computer, and then I can control it and I can use it, instead of just bringing my own," said Stig Langvad, who heads up Denmark's umbrella organization for people with disabilities. "So I'll be a part of society on an equal foot, instead of being a special solution." We can learn from the passage that _ .

For many workers trying to lose weight, the weekend is a chance to do some exercise and eat something healthier than a supermarket sandwich at their desk. But some slimmers take a slightly different approach -- consuming more than half their weekly calorie intake from Friday night to Sunday. Away from the daily routine at work that helps them keep control of what they eat, they are snacking and drinking their way to a shocking 10,000 calories, a survey has found. Almost three-quarters of people trying to lose weight admit to over-eating at the weekend. A meal with friends or family, complete with alcohol, as well as a late-night snack before bed, can lead to adults consuming up to 3,500 calories in one day, a survey found. Men typically need 2,500 calories a day and women 2,000 calories. Consuming this amount would see men and women get through half their weekly calorie intake over the course of a 'bad' weekend. Women were found to eat less on a Sunday because of guilt over their consumption over the previous two days. Men had fewer doubts about a third day of excess. The biggest weekend diet danger comes from snacking between meals, the survey found. Some say they will often spend Saturday night in front of the TV with their families -- combining watching their favorite shows with crisps and biscuits. And seven in ten people admitted to having fattening takeaways at weekends, with pizza the most popular. Alcohol is another big factor in weekend bingeing.Around 70 percent still like to have a roast on a Sunday or a big meal with family or friends and a third of those will have second helpings. A spokesman from Forza Supplements, the diet company that conducted the survey, said, "We all have bad weekends where we have a lot of fun, but dieting goes out of the window." The 5:2 diet is becoming increasingly popular -- where we limit our calories for five days and allow ourselves a few treats on the other two days.

We have known for a long time that flowers of different plants open and close at different time of day. Yet no one really understands why flowers open and close like this at particular times. It is not as simple as we might think, as new experiments have shown. In one experiment, flowers were kept in darkness. We might expect that the flowers, without any information about the time of the day, did not open as they usually do. In fact, they continued to open at their usual time. This shows that they have some mysterious way of knowing the time. Their sense of time does not depend on information from the outside world; it is, so to speak, inside them, a kind of "inner clock". This discovery may not seem to be very important. However, it was later found that not just plants but also animals including man have this "inner clock"which controls working of their bodies and their activities. Human beings, then, are also controlled by this mysterious power. Whether we wish it or not, it affects such things in our life as our need for sleep, our need for food.

But now 400 organizations in the UK,from playgroups to the National Health Service,are encouraging children to have some"wild time".They want kids to swap at least 30 minutes of watching TV or playing computer games for time playing outside.Activities such as building dens, climbing trees, rummaging for conkers and playing hide and seek are just some of the things kids can do. Even if they live in a city,they can go on adventures in the garden or the park. Children often need a helping hand from mum and dad.They need to be shown what to do and where to go.Andy Simpson from National Health Service says,"We want parents to see what this magical wonder product does for their kids' development,independence and creativity,by giving wild time a go".

The answer from that big industry was "No". Paul then went to college to study the science of plants. Unfortunately, his teachers said there weren't any birds or squirrels to spread the seeds. It would be a waste of his life to try to do it. Everyone knew that, he was told. Even if he was knowledgeable as he had expected, he wouldn't get his idea accepted. Paul later got married but his dream would not die. And then one night he did what he could with what he had. As Samuel Johnson wrote, "It is common to overlook what is near by keeping the eye fixed on something remote. Attainable good is often ignored by minds busied in wide ranges." Under the cover of darkness, he went secretly into the wasteland and started planting. And every week, he made his secret journey into the wasteland and planted trees and grass. For fifteen years he did this against _ . Slowly rabbits appeared. Later, as there was legal pressure to clean up the environment, the company actually hired Paul to do what he was already doing. Now the place is fourteen thousand acres of trees and grass and bushes, and Paul has received almost every environmental award Utah has. It took him until his hair turned white, but he managed to keep that impossible vow he made to himself as a child. Paul went to college to study the science of plants, because _ .

In order to make students become more interested in English studies,21 elementary schools in southeastern Korea have started to use robot teachers. The robot teacher is called Engkey. She was developed by the Korea Institute of Science and Technology. She is about one meter high and is white,egg-shaped. She takes a display panel as her face. She can move around the classroom while she speaks to students. She can also read books to students and dance to music by moving her head and arms. Now,21 robot teachers have been used to teach English. They are controlled by English teachers in the Philippines. There is a camera in each of the robot teachers. With the help of the cameras,English teachers in the Philippines can see and hear the students. At the same time,the facial expressions of these English teachers. This is very interesting. Besides helping students to become more interested in English,the robot teachers can also help children in poor areas without English teachers. Robot teachers have many good points. For example,they needn't have a rest because they don't get ill. Why have schools in southeastern Korea stared to use robot teachers?

More than 2.25 billion cups of coffee are drunk throughout the world each day, and it's likely that many taste bitter. Now, a new study suggests that coffee fans can make their drink sweeter by changing the color of their cups. Researchers from Oxford set out to prove whether the claim that coffee drunk from a white cup tastes biter was true. They used 36 volunteers and three different colored cups---blue, white and transparent glass--- to examine the claim. In one experiment, the white cup increased the intensity of the coffee taste relative to the transparent cup. Then, in a second experiment, coffee drunk from the white cup was found to taste less sweet when compared to the other colored cups, while the blue cup made the coffee taste the sweetest. The scientists believe that the color brown may be associated with bitterness, and coffee in a white cup appears the brownest. "Our study clearly shows that the color of a cup does influence our sense of the coffee taste," leading author Dr George Doorn, wrote in an article for The Conversation. "The effect of the color of the cup on the taste of the coffee reported here suggests that cafe owners should carefully consider the color of their cups," he said. "The potential effects may spell the difference between a one-time purchase and a return customer." Actually, the idea that color can change the food and drink taste came out many years ago. A study published last year reported that red, strawberry-flavored cake served on a white plate was rated as 10 percent sweeter than the same food presented on a black plate. The passage is mainly about _ .

Everywhere man is altering the balance of nature.He is facilitating the spread of plants and animals into new regions, sometimes deliberately, sometimes unconsciously.He is covering huge areas with new kinds of plants, or with houses, factories, slag-heaps and other products of his civilization.He exterminates some species on a large scale, but favours the multiplication of others.In brief, he has done more in five thousand years to alter the biological aspect of the planet than has nature in five million. Many of these changes which he has brought about have had unforeseen consequences.Who would have thought that the throwing away of a piece of Canadian waterweed would have caused half the waterways of Britain to be blocked for a decade, or that the provision of pot cacti for lonely settlers' wives would have led to Eastern Australian being overrun with forests of Prickly Pear? Who would have prophesied that the cutting down of forests on the Adriatic coasts, or in parts of Central Africa, could have reduced the land to a semidesert, with the very soil washed away from the bare rock? Who would have thought that improved communications would have changed history by the spreading of disease-sleeping sickness into East Africa, measles into Oceania, very possibly malaria into ancient Greece? These are spectacular examples; but examples on a smaller scale are everywhere to be found.We make a nature sanctuary for rare birds, prescribing absolute security for all species; and we may find that some common and hardy kind of bird multiplies beyond measure and ousts the rare kinds in which we were particularly interested.We see, owing to some little change brought about by civilization, the starling spread over the English country-side in hordes.We improve the yielding capacities of our cattle; and find that now they exhaust the pastures which sufficed for less exigent stock.

Death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two phases --- clinical or temporary death and biological death. Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage. The organism can still be revived . Biological death occurs when changes in the organism lead to the "breaking up" of vital cells and tissues. Death is then unchangeable and final. Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic sleep. By slowing down the body's metabolism , cooling delays the processes leading to biological death. To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from an artery. The monkey's blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing. After two minutes Keta's heart became active once more. After fifteen minutes, spontaneous breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe and ran with it around the room. Her behavior differed little from that of a healthy animal. How did the scientists put Keta into clinical death?

Laughter healing benefits and healing with laughter have become synonymous with Norman Cousins, the man who laughed himself to wellness. Norman Cousins was the editor of SaturdayReviewfor over 30 years. His story began in 1964, when doctors found that the connective tissue in his spine was becoming worse, which is a condition known as Ankylosing Spondylitis . The doctors, one of whom was a close friend of Cousins, said that his chance of survival was approximately 1 in 500. He read about the theory that negative emotions do harm to the body, so he thought that if negative emotions were damaging to health, then positive emotions should improve health. Faced with the real possibility of his approaching death, Cousins thought long and hard and eventually did three things completely contrary to medical opinion. First he began his own research on all of the various drugs he was on. He discovered that his condition was removing Vitamin C from his body and, based on Cousins' personal research, doctors agreed to take him off several of the drugs he was on and inject him with large doses of this supplement , as Cousins felt this may be his last hope. Secondly, Cousins made a decision to check out of the hospital and into a hotel room. The third thing Cousins did was get a movie projector and a large supply of funny films. On his first night in the hotel Cousins found that he laughed so hard at the films that he was able to stimulate chemicals in his body that allowed him several hours of pain-free sleep. When the pain returned he would simply turn the projector back on and the laughter would help sleep, and he was able to measure the changes in his body by measuring his blood sedimentation rate , and found that this rate dropped by at least 5 points each time he watched one of these videos. The treatment proved to be so effective that in very little time Cousins was off all painkillers and sleeping pills. He found that the laughter relieved the pain and helped him sleep. He returned to work and wrote about his experimental treatment in his book Anatomy of an Illness. In 1989, it was finally acknowledged in the Journal of the American Medical Association that laughter therapy could help improve the quality of life for patients with chronic illness and that laughter has an immediate symptom-relieving effect. We can learn from the passage that Norman Cousins _ .

If you are sitting down listening to what I'm going to say, stand up. Move your legs. Touch your toes, if you can. Do anything but sit. If you cut down on the time you spend sitting, you might live longer. New research shows that sitting less than three hours a day might extend your life by two years. Just the opposite, says Peter Katzmarzyk. He is a scientist at the University of Louisiana in the southern United States. He says that sitting is _ in our lives. "We sit while we're eating; we sit in the car; we sit while we watch TV. Many of us sit for many hours at work. " But, he adds, that does not make sitting good for us. The human body is designed to move. But modern lifestyles and office jobs rarely give us the chance to move around. Exercise is important. So is not sitting. "We can't throw away physical activity. It's extremely important. We have 60 years of research showing us that. Even if you exercise for 30 minutes a day, what goes on in the other 23-and-a-half hours a day is also very important." Mr. Katzmarzyk and his co-workers are part of a new generation of researchers studying how sitting all day affects length of life. This is a relatively new area of study--studies that have assessed the relationship between sitting and mortality or television viewing and mortality. Making uses of the few studies available to them, they found that cutting television time to less than two hours a day could add one-point four years to life. New desk designs are helping Change is already coming to some offices, especially in the design of desks. A "standing desk" lets people stand while they work. Another new design is called the "treadmill desk." A treadmill is an exercise machine that lets you walk in one place. That's one of the strategies that many companies are using now. Some companies may equip their employees with a "standing desk" or a "treadmill desk". Other companies may not buy one for everybody, but they'll have a bank of these desks where people can go for an hour a day and answer their emails or talk on the phone. Even some U.S. schools are beginning to experiment with such desks to keep children moving. Mr. Katzmarzyk says studying this problem has inspired his team to make a few changes in their own lives. "As a university professor, you know, it is a very sedentary occupation. We're chained to a desk in terms of writing papers and doing research. We really try to limit the amount of time we spend doing that." Suggestions for sitting less If you work in office job or have a sedentary job, Mr. Katzmarzyk and his team suggest a few simple changes: get up from your desk as often as you can take walks at lunch time walk to your colleagues' offices and talk directly instead of emailing them All these activities may help you live longer. Mr Katzmarzyk holds the view that _ .
