mmlu_train_54391 | Will online courses transform world of education? Some may wonder what it feels like to attend a class at Stanford University. The recently popular MOOCs (Massive Open Online Courses) can satisfy this desire. But they are also most likely to change the situation of higher education. Only last month,both Peking University and Tsinghua University announced plans to start open online course on the edX platform,one of the world's major providers of MOOCs,to explore this new form of online education. Gaining momentum "It's not only a change of platforms from offline to online. It's more about a reform of teaching methods,even the whole education system,"said Chen Jining,president of Tsinghua University. The potential of MOOCs to reform education has been obvious in the US ever since the immediate popularity of the course Artificial Intelligence,taught by Stanford University professor Sebastian Thrun, who later co-founded Udacity, a platform with 1.6 million enrolled students in 200 countries. According to Nature magazine,by June 2013,74 percent of universities in the US offered some type of online course. Lu Fang, vice-president of Fudan University,explains the appeal of MOOCs as a simple case of supply and demand:"The demand for high quality educational resources from both enrolled students and professionals is feeding the rise of MOOCs,in which classes usually taught by top teachers are available to everyone,"said Lu. Too early to replace With easy access and free of charge, MOOCs are said to have the potential to change the present education system. But there are barriers,because hardly any universities offer degree certificates, as college administrators point out, it's difficult to confirm if students are foaming anything in MOOCs,reposed USA Today. The Wall Street Journal also reposed that,presently,a typical MOOC student is likely to have already graduated from college and is using the course to explore an interest or acquire professional skills. Even so, an increasing number of undergraduates are signing up. "What we are really establishing are educational pathways for people who want skills that are related to contemporary jobs,"Thrun told The Wall Street Journal. What can we learn from the passage? | [
"Most of the MOOCs focus on professional training for college graduates.",
"There are barriers for MOOCs to replace the present education system.",

Apes all belong to the hot countries of the world--tropical Africa and South--east Asia. The gorilla is the largest of the apes. He is as tall as six feet when standing upright. Many people think that gorillas are very fierce. They are often described as standing upright like a man, beating their fists and roaring. In their home, in the forests of Central Africa, however, they are not at all like this, They are peaceful animals and never use their great strength unless attacked. Even then, they retreat if they can. Gorillas have black faces and long, black, hairy coats. They feed during the day on plants and fruit. At night the old male often sleeps on the ground at the foot of a tree, while the others each make a sleeping platform in the tree bending the leafy branches.

mmlu_train_48128 | The air bag is a piece of safety equipment in cars. It was first designed by John W. Hetrick in 1952. Like many inventions, he came up with the idea as a result of an event that had occurred in his life. He says: "In the spring of 1952, my wife, my seven-year-old daughter, Joan, and I were out for a Sunday drive in our 1948 Chrysler Windsor. About three miles outside Newport we were watching for deer jumping across the road. Suddenly, there was a large rock in our path. I hit the brakes and we went into a ditch . "As I applied the brakes, both my wife and I threw our hands up to keep our daughter from hitting the car. There was soft mud in the ditch, so the car wasn't damaged, and no one was hurt." "During the ride home I couldn't stop thinking about the accident. I asked myself,'Why couldn't some object come out to stop you from striking the inside of the car?'As soon as I got home that night I drew some sketches . Each evening for the following two weeks, I'd add or reduce something from the sketches." Hetrick applied an event he had observed while in the Navy to the design of the air bag. He was repairing a torpedo which had a cloth covering. When the compressed air that was in the torpedo was let out, the covering was suddenly filled with air and was shot to the ceiling. With this knowledge, he developed his design until he was able to obtain a patent on the invention on August 5, 1952. The idea was similar to the air bag designs of today. Compressed air is stored in a container and when a traffic accident occurs and the car slows down at a rapid enough rate, the air will be released into the air bag. The idea was _ , but Hetrick's air bag never would have functioned properly. It was really a breakthrough, but it would require years and years of designing and testing by some top car designers before it could be used. The text is mainly about _ . | [

mmlu_train_43572 | Everyone takes drugs. Sometimes a drug might be called a herb but the effect is the same. Drugs and herbs can make life better for they are used to improve health. From the simplest headache to a cure for cancer, People believe that certain drugs can help them. But there is danger if the drugs are not used in a proper way. American teenagers sometimes use certain drugs to feel good. They call this "getting high". The problem is that once a young man or a young woman has the feeling of "getting high, they want to do it often. If school is boring or too hard, students might get depressed and a drug or herb might help them feel better. If a student takes too much of a drug, the body may change in a negative way such as a confused mind, poor vision, a headache, and an uncomfortable stomach. School mow have DARE programme which means Drug Abuse Resistance Education. This programme was started so that young students from age 10 to18 might understand how a drug affects their bodies. The main point of the programme is education. Once a student understands certain drugs can cause ill health, he will know he should not use them. Education is the key to good nutrition as well. If a student eats correctly, he or she will be full of energy which leads to good study habits and good grades. Poor nutrition may cause the need for more sleep and poor concentration. Proper food is similar to the proper use of drugs. Both allow a healthy body to grow while misuse prevents a person from developing normally. The main aim of DARE programme is to _ . | [

It took 200 Chinese scientists two years to build the fastest supercomputer. It can do 2,507 trillion calculations in a second! That means it will take a personal computer 600 years to finish the work that a supercomputer does in a day! The US now leads the world in the area of supercomputers. It is home to more than half of the world's top 500 supercomputers. Japan also has advanced technology. China is developing its supercomputer technology quickly. But experts say it will take years before China's total computing power can catch up with that of the US. Supercomputers can work on many different things. They can solve problems in areas like national defense , energy and science. In business, you can also use supercomputers. Oil companies use them to find oil and gas. Banks use them for quick trades. Food companies even use supercomputers to make sure that they put potato chips into cans without breaking them. To make a supercomputer, scientists first need to link thousands of small computers together. Then they use software to turn them into one supercomputer. In fact, any person with enough knowledge about computers can make a supercomputer. But you need the top technology to make a supercomputer run fast.

mmlu_train_20089 | Most people know Alexander Graham Bell invented the telephone. But not many know about another talking device (equipment) he invented just four years later, in 1880. He called the device the photophone. "Photophone" comes form the Greek words for "light" and "sound". The photophone did not use electricity to carry sound over wires between two people. _ . Instead, the photophone used a beam of sunlight traveling through the air. With his invention, Bell could actually transmit human speech on a beam of light. To do so, he spoke close to a thin mirror that was reflecting sunlight. The vibrations of his voice caused the mirror to vibrate, and the vibrating mirror caused the light to vibrate. The vibrating light hit a light-sensitive cell in a receiver placed some distance away. The cell changed the light patterns into electrical signals. Earphones changed the signals back into sounds. Bell believed that his idea of talking on a beam of light would prove to be important. He often called the photophone his greatest invention. Even though the photophone depended on a source of energy that was not constant--the sun--Bell wasn't a bit discouraged. He felt sure that people would one day talk using beams of light. Two much more recent developments made Bell's dream come true. In 1960, a scientist built the laser. A laser produces a highly concentrated beam of light. Shortly afterward, other scientists developed a new kind of optical fiber. The optical fiber is a glass thread. The new fiber could carry light beams long distances--as far as several miles. According to Bell's own opinion, _ is his greatest invention. | [

So at the least sign of hot sun, a snail draws its body into its shell and closes the opening with a thin cover. Then it goes to sleep. A snail will die in a heavy rain. So whenever it rains, it goes inside its shell house and goes to sleep. A snail can sleep for as long as it needs to. It can take a short sleep. Or it can sleep for days at a time. And it spends all the winter months in its shell, asleep. In spring the snail wakes up. Its body, about three inches long, comes out of from the shell. When hungry, the snail looks for food. It can't see very well. Its eyes, at the ends of the top feelers are very weak. But its sense of smell is very strong. It helps the snail to the new greens.

I was lucky: I became a pilot in 1970, almost ten years before I graduated from medical school. I didn't realize then, but becoming a pilot makes me a better surgeon. I loved flying. As I flew bigger, faster planes, and in worse weather. I learned about crew resource management , or CRM, a new idea to make flying safer. It means that crew members should listen and speak up for a good result, regardless of positions. I first read about CRM in 1980. Not long after that, an attending doctor and I were flying in bad weather. The controller had us turn too late to get our landing ready. The attending doctor was flying; I was safety pilot He was so busy because of the bad turn, he had forgotten to put the landing gear down. He was a better pilot - and my boss - so it felt unusual to speak up. But I had to: Our lives were in danger. I put aside my uneasiness and said, "We need to put the landing gear down now!" That was my first real lesson in the power of CRM, and I've used it in the operating room ever since. CRM requires that the pilot/ surgeon encourage others to speak up. It further requires that when opinions are from the opposite, the doctor doesn't overreact, which might prevent fellow doctors from voicing opinions again. So when I'm in the operating room, I ask for ideas and help from others. Sometimes they're not willing to speak up. But I hope that if I continue to encourage them, someday someone will keep me from " _ ". Which of the following can be the best title for the text? | [

There is a limit to what robots can tell us, though, so eventually we will have to send people to study the planet. Before people can visit Mars, we need to invent a spaceship that can take us there. Mars is very far away. Depending on where Mars and Earth are in their orbits around the sun, it could take between six months to a year to get there. The moon is much closer, and we were there, 25 years ago. Over the next 10 years, we are going to work on building a new spacecraft that can go to the moon. Using this craft, we will practice the skills we need to go to Mars. Once we return to the moon, we are going to build a station so that people can live and work on the moon for months at a time. This is important so that we have a place to start from when we want to visit Mars, but it is also important because it gives us practice with living away from Earth. By the time you are old enough to be an astronaut, we will have people spending months on the moon. By the time you are old enough to be a commander of a space mission, we will be taking trips to Mars. By the time your kids are old enough to be astronauts, we may have people living on Mars.

In a coffee shop you sit at the counter or at a table. You don't wait for the waitress to show you where to sit. She usually brings you coffee when you sit down. You tell her what you'd like to eat and she brings it to you. You pay the cashier as you leave. A diner is like a coffee shop but usually looks like a railway carriage. In a family restaurant the atmosphere is casual, but the waitress shows you where to sit. Often the waitress tells you her name, but you don't need to tell her yours. If you don't eat everything, your waitress gives you a doggy bag to take your food home. You add an extra fifteen percent to the bill as a tip. In top class restaurants, you need a reservation and you need to arrive on time. The waiter shows you where to sit. If you have wine, he may ask you to taste it. You can only refuse it if it tastes bad, not if you don't like it. When you get your bill, check it and then add fifteen to twenty percent to it as a tip for the waiter.

mmlu_train_62906 | Work Your Mind Here's something to think about the next time you ask your teacher for help: struggling with schoolwork on your own can help you learn. According to a recent study, the more you struggle while you are learning new information, the better you can remember it later. This theory might surprise you. When teachers are presenting new information, they often give students lots of help. But a new study shows this may not be the best way to support learning. "Don't be too quick to get help when learning something new," education expert Manu Kapur told TFK. "Try to work on it yourself even if it means trying different ways." Kapur came up with the idea that struggling can lead to better learning. Then he tested it out on students in Singapore. He separated students into two groups. In the first group, students were asked to solve math problems with the teacher's help. In the second group, students were asked to solve the same problems by helping one another, instead of getting help from the teacher. With the teacher's help, students in the first group were able to find the correct answers. Students in the second group did not solve the problems correctly. But they did come up with a lot of good ideas. The students were then tested on what they had learned. The group without any help from a teacher scored much higher than the group who had help. Kapur said working to find the answers helped students understand the process, not just the solution. Kapur's advice for kids is to put a lot of effort into learning something new rather than going to your teacher for help. "Simply doing a little work or nothing at all won't work," says Kapur. "The struggle needs to be a genuine attempt to figure out or solve a problem in as many ways as possible." What's Manu Kapur educational idea on learning new knowledge? | [

The sick person falls into a kind of sleep, and when he awakes, the operation is finished. But these happy conditions are fairly new. It is not many years since a man who had to have operation felt all its pain. Long ago, operation had usually to be done while the sick man could feel everything. The sick man had to be held down on a table by force while the doctors did their best for him. He could feel all the pain if his leg or arm was being cut off, and his fearful cries filled the room and the hearts of those who watched. Soon after 1770, Josept Priestley discovered a gas which is now called "laughing gas".Laughing gas became known in America.Young men and women went to parties to try it. Most of them spent their time laughing,but one man at a party,Horace Wells,noticed that people didn't seem to feel pain when they were using this gas.He decided to make an experiment on himself.He asked a friend to help him. Wells took some of the gas,and his friend pulled out one of Well's teeth.Wells felt no pain at all. As he didn't know enough about laughing gas, he gave a man less gas than he should have. The man cried out with pain when his tooth was being pulled out. Wells tried again,but this time he gave too much of the gas,and the man died.Wells never forgot this terrible event.

mmlu_train_18693 | Do you know electricity can change the way we taste food?Proving this fact is a revolutionary electric fork designed by Japanese researchers that can make any dish taste salty. According to Hiromi Nakamura,a Post Doc Research Fellow at Tokyo's Meiji University,the technology can be very useful for people on special diets.Patients with high blood pressure,for instance,can easily go on a low-salt diet and still enjoy delicious food.And with the fork,there's ly no risk of over-salting their food.Luckily,the voltage is so small that there is no risk of electrocution either. The idea of adding electricity to food was first exposed as an experiment at the Computer Human Interaction Conference in Austin,Texas,in 2012.Nakamura and her team connected a wire to a 9-volt battery and passed it through a straw placed in a cup of sweet lemonade.Volunteers reported that the charged lemonade tasted'blander',because the electricity created the taste of salt. Nakamura has improved the technology to be able to transfer an electric charge to food through forks and chopsticks."The metallic part of the fork is one electrode ,and the handle is the other,"Nakamura explained."When you take a piece of food with the fork and put it in your mouth,you connect the circuit.When you remove the fork from your mouth,you disconnect the circuit.So it actually works as a switch." Simon Klose,host of food program Munchies,who recently visited Nakamura to try out the fork himself,called this form of'food hacking'one of the greatest eating experiences he'd ever had. "When I first heard of electric food,it sounded scary,"he said.He later continued to use a charged fork to eat pieces of fried chicken,and found that the saltiness considerably increased as the electricity was connected. Nakamura has been eating'electric'food for the past three to four years in an attempt to understand it better."For me,'food hacking'is about strengthening or weakening real food,"she said."It may seem like we're cooking but we're actually working on the human senses."

Any large hospital will tell you the number of the accidents that happen in the home is almost the same as those on the road. One of the commonest and most dangerous causes of home accidents is wrong and careless use of electrical equipment. People will continue to use a loose plug or pull out a plug without first turning off the power. In spite of warnings, one will carry an electric heater into the bathroom when he is going to have a bath. Sometimes one forgets to cut off the power before mending a lamp or something else. All this will cause accidents. So the rule about anything that work by electricity is:Switch off before you touch anything and don't pretend you know when you actually don't. If you've got children in the house, it's always best to keep medicines of any kind out of their reach. Otherwise, they may be taken for candies or a new kind of drink. When there are older people living with you, you have to take particular care in a number of ways in order to make them safe and happy. Fire, of course, is always a risk. So, remember not to dry clothes in front of fires, or leave stoves in the middle of rooms where they can easily be knocked over. And don't forget to keep the children away from fire. Smoking, too, may cause fire. So you'd better give it up. Safety first may mean a little more time and care, but it may save you a lot of trouble. We can learn from the text that _ . | [

mmlu_train_52428 | There is no doubt that Apple is well aware of the increased competition in the market and could be in a hurry to put another device out there, said Ramon Llamas, senior research analyst at IDC Mobile Devices Technology and Trends. Given its history with product launches and business policy, though, Apple probably isn't going to rush an iPhone release simply to put it on shelves, he said. "If you're Tim Cook (CEO of Apple), you're thinking if you want to pay more attention to how to keep growing that bottom line and keep investors happy, or continue with the same approach from Apple, which is do what we can do and manage products and releases in the best way they can work for us. Apple usually does things in their own time ,and I'm having a hard time buying this May or June timeline." Llamas told Mac News World. While it,s probable that Apple is definitely in a testing stage for its next smartphone , consumers likely have a standard wait for the finished product, said Colin Gibbs, analyst at GigaOm Pro. "It typically takes a year or longer to create a state-of-the-art smartphone, so no one should be surprised Apple is in the testing stages with the next iPhone. And while it's possible that Apple could launch the next iPhone this spring or summer, I'm not expecting to see it until a little later in the year," he told Mac News World. When it does launch, though, it could be in a variety of colors, said Gibbs. "Apple has already tested the waters with releasing colored devices when it revamped(,)its iPod line last fall, so it's not too much of a stretch to believe it would want the new twist with its smartphone, as well". "I wouldn't be surprised if the new iPhone becomes available in some new colors,'' he said. "That could be done pretty cheaply ,and it would give Apple a new marketing angle."

Experts say teens are biologically programmed to go to sleep later and wake up later than other age groups. Yet many schools start classes as early as seven in the morning. As a result,many students go to class feeling like Danny,16 years old. He plays two sports,lacrosse and football. He is an active teen--except in the morning. DANNY:"Getting up in the morning is pretty terrible. I'm just very out of it and tired. And through first and second period I can hardly stay awake." Michael Breus,a clinical psychologist with a specialty in sleep disorders says:"These aren't a bunch of lazy kids--although,you know,teenagers can of course be lazy. These are children whose biological rhythms,more times than not,are off."Teens,he says,need to sleep eight to nine hours or even nine to ten hours a night. He says sleepy teens can experience a form of depression that could have big effects on their general well-being. It can affect not just their ability in the classroom but also on the sports field and on the road because any tired driver is dangerous,especially a teenager with a lack of experience. So what can schools do about sleepy students?The psychologist says one thing they can do is start classes later in the morning.

Anyone clever enough to modify this information for his own purposes can get big reward. Even worse, a number of people who have done this and been caught at it have managed to get away without punishment. It's easy for computer crimes to go undetected if no one checks up on what the computer is doing. But even if the crime is detected, the criminal may walk away not only unpunished but with a glowing recommendation from his former employers. Of course, we have no statistics on crimes that go undetected. But it's disturbing to note how many of the crimes we do know about were detected by accident, not by systematic inspections or other security procedures. The computer criminals who have been caught may have been the victims of uncommonly bad luck. Unlike other lawbreakers, who must leave the country, commit suicide, or go to jail, computer criminals sometimes escape punishment, demanding not only that they not be charged but that they be given good recommendations and perhaps other benefits. All too often, their demands have been met. Why? Because company executives are afraid of the bad publicity that would result if the public found out that their computer had been misused. They hesitate at the thought of a criminal boasting in open court of how he juggled the most confidential records right under the noses of the company's executives, accountants, and security staff.

Morrissey believes that variety is not only the spice of life,it's the foundation of a healthful diet. Diets which are based on one or two foods are not only almost impossible to keep up the strength,they can be very harmful, she says, because nutrients aren't supplied in enough amounts or balance.

For thousands of years, people have wondered about this big thing in the sky. Earth's moon is a satellite. A satellite is a body that orbits a planet. All moons are satellites, and many planets have them. Some have many moons. Earth, of course, only has one. It's a special moon, though. It's the fifth largest moon in the solar system! In fact, the moon is much smaller than the sun. But it's much closer to Earth, so it looks as big as the sun. The moon is so close that you can see its dark and light spots without a telescope. Men flew and landed on the moon's surface many times by spacecrafts in the 1960s and 1970s. Neil Armstrong was the first human to step on the moon. He walked on the moon on July 20th, 1969. The flights to the moon have helped us learn much about it. Astronauts even brought rocks home with them! There's still a lot to learn about the moon. Now people still can't live on the moon because it does not have oxygen or water like the Earth. But I'm sure that humans can live there one day in the future. ,.

mmlu_train_40053 | I'm glad to find this comment which has some sort of support in this quest I have to eat raw foods. I'm an unhealthy 49 years old and have come to the conclusion that it's now or never, so I am taking a dive into the raw eating lifestyle. I have to cook for my family and prepare what they want to eat. I'm trying to plan out this better so I have some of these unusual foods ready for myself. I've read several books written by Ann Wigmore and like her approach to the living foods. Last week I attempted fasting and failed. I lasted five days by having carrots, spinach, apples and other vegetarian diets I could get my hands on. I was doing fine until I drank some coffee. I kind of proved it in my mind to have the coffee but it only made me excited and then I couldn't sleep well and felt hungry and weak. So I stopped and went back to the old way of eating with the family. This week I started to make a drink called rejuvelac made of sprouted wheat . This is fairly new to do for me and the drink smelled sort of musty and tasted kind of like a musty lemon. The kids tasted it and almost threw up but surprisingly it tasted good to me. It is supposed to help in digestion . I've made some attempts to grow wheat grass. I think I have figured that out as long as I keep it away from birds and our horses. I have two habits to get rid of, drinking coffee and smoking. I quit smoking last month but something happened, so I started up again. I'm very frustrated with the smoking and really have a desire to quit for good. Anyhow I will keep this updated on my progress. The author must have _ before she wrote this article. | [

mmlu_train_37170 | The US space agency NASA is looking for people to go to Mars, and stay there. This attractive career is for people who want a huge change of scenery and planet. The project is called the Hundred Years Starship, which aims to colonize other lands such as the red planet Mars. Settlers would travel to the red planet and live there forever. NASA says it would be too expensive to bring humans back to Earth. The space agency can afford, however, to send supplies to the astronaut pioneers from Earth. Astronauts would be landed on the planet's surface and would never be able to return home due to the cost. NASA has started the project with $1.6 million, and hopes to attract investment from space-living billionaires. Google co-founder Larry Page told NASA he would be interested if the cost of a one-way ticket can go down from $10 billion to $2 billion. The journey to Mars could take 4 months. Setting on the red planet would be extremely dangerous, especially given the freezing temperatures there. The thin atmosphere would be another problem as it is mostly carbon dioxide, so oxygen supplies are a must. A director in NASA said that he believed the trip might start with visiting Mars's moons first. He claimed that humans could be on Mars's moons by 2030. Many scientists think colonizing space is absolutely necessary. Steven Hawking believes we must move to other planets to survive as a species. He said: "Once we spread out into space and establish independent colonies, our future should be safe." Scientists Dirk' Schulze-Makuch and Paul Davies also call it a "desirable goal", though there surely are huge risks to explore new lands.

And international agreements that laid out the standards, regulations and practices gave rise to a global mobile phone industry. To be honest, the world's first mobiles were not so attractive and the range of effectiveness wasn't very good. But they became a must-have among those wealthy people who could afford that. However, by advantage of GSM which has many different elements to it, we can all enjoy the ability to go around the world in 217 countries, land in that country and know that a phone would work. There are other cell phone systems using different technology in the world. The majority of the United States and parts of South America have been using something called CDMA which is very rare in Europe. In some Asian countries like China, GSM and CDMA both exist at the same time. But the GSM Association claims 85% of the global mobile phone market. They estimated there are now about 2.5 billion different users who make more than 7 trillion minutes of calls everyday, and that's not all. 20 years later, the mobile phone is so much more than just a phone. You can use it to send text messages, take pictures, show video, even surf the internet. "The phone itself is involved from just being a communication tool, to be a tool for round-the-clock connectivity, you can not live without it even in a minute." Mobile consultant Nick Lane also points out with so many customized styles and features, your mobile phone will become a symbol of you. Where will the global mobile phone industry be in another 20 years? Certainly, there will be more connections than better coverage. As for where else technology will take us, one can only imagine.

mmlu_train_38749 | Boys and girls,as we all know,most people,especially young people ,tend to care about their hair much because hair plays a very important role in our appearance.But can you imagine what other uses hair has?Do you have any idea that human hair may become a new solar energy soutce?Before we begin with the new content of our Physics ,let me tell you a new invention first. It's reported that a Nepali teenager has designed a $32 solar panel using human hair. Milan Karki,who is 18 years old and lives in a village in rural Nepal,used human hair to replace silicon ,which is a common but expensive componet of solar panels. By using hair as a replacement,Karki says that solar panels can be produced for around $32,a price that could be halved if they were mass-produced. The solar panel works,because melanin ,which gives hair its colour,is light sensitive and can act as an elecrtical conductor.Kaiki was inspired to think of the idea by a Stephen Hawking book ,which explained how to create elecrtic energy from hair. The device that Karki has invented is capable of producing 9V or 18V of energy--plenty to charge a mobile phone. "Half a kilo of hair can be bought for only 16p in Nepal and lasts a few months;whereas a pack of batteries would cost50p and lasts few nights,"according to The Daily Mail. The solar panel is claimed to be easy to service as the hair is easy to replace. Karki has now seng out several devices to other disrticts near his home for tetimg .He said,"First I wanted to provide elecricity for my home,then my village .Now I am thinking for the whole worle." So next time when you have a haircut,do remember to keep your hair cut down to use for energy.Perhaps you can also provide elecrticity for your home,even your village using your own hair.

mmlu_train_28131 | Not long ago, many people believed that babies only wanted food and to be kept warm and dry. Some people thought babies were not able to learn things until they were five or six months old. Yet doctors in the United States say babies begin learning on their first day of life. The Eunice Kennedy Shriver National Institute of Child Health and Human Development is a federal government agency. Its goal is to determine which experiences can influence healthy development in people. Researchers at the institute note that babies are strongly influenced by their environment. They say a baby will smile if her mother does something the baby likes. A baby learns to get the best care possible by smiling to please her mother or other caregiver. This is how babies learn to connect and communicate with other people. The researchers say this ability to learn exists in a baby even before birth. They say newborn babies can recognize and understand sounds they heard while they were still developing inside their mothers. Another study has suggested that low birth weight babies with no evidence of disability may be more likely than other children to have physical and mental problems. American researchers studied almost five hundred boys and girls. They were born in, or admitted to, one of three hospitals in New Jersey between 1984 and 1987. At birth, each child weighed fewer than two thousand grams. The boys and girls had an average age of sixteen at the time of the study. They were asked to complete intelligence and motor skill tests in their homes. Their test results were compared with those of other children their age.

mmlu_train_47095 | People who are worried about bad breath often reach for a toothbrush or a gun. But in the future, personal breath monitoring may include far more than fresh breath. In face, breath is so rich in chemical compounds that fully understanding it has proved challenging. Each breath contains gases like carbon dioxide, the volatile remains of recent snacks, medicines and even compounds taken in from things like carpeting or various kinds of air pollution. But breath detectors can sort out these substances with increasing sensitivity . Scientists are building electronic sniffers that examine the exhaled air for signs of cancer, asthma , and other diseases. "There are clear signatures in the breath for liver disease, kidney disease and heart disease. Breath is a rich mixture that can reflect out state of health and disease." said Dr. Raed Dweik, director of the Cleveland Clinic, adding "Breath analysis is the future of medical testing." He and his partners are testing a desktop system called BreathLink for use in rapid identification of diseases. The system is designed to work wherever there is an Internet connection. To use BreathLink, a person breathes into a long tube, and a breath sample is collected and analyzed within the system. Then it can detail chemical concentrations of the breath in graphics. Dr. Raed Dweik said, "If you examine patients of asthma, you will find they have higher levels of nitric oxide in their exhaled air. It reflects their abnormal symptoms in the lungs." His tests have reached 85 percent accuracy so far in spotting people with some illness. But some trained dogs, he pointed out, can sniff out cancer with 99 percent accuracy--although without the ability to identify particular compounds the way some detectors can. "We are getting better and better," he said. "But whether we will ever approach the accuracy of the dog--we don't know." What is the breath detector used for? | [

mmlu_train_20558 | NEW YORK (Reuters Health)--Kids who eat better perform better in school, a new study of Nova Scotia fifthgraders confirms. Students who ate an adequate amount of fruit,vegetables,protein,fiber and other components of a healthy diet were significantly less likely to fail a _ test,Dr.Paul J.Veugelers of the University of Alberta in Edmonton and colleagues found. While a healthy diet is generally assumed to be important for good school performance, there has actually been little research on this topic, Veugelers and his colleagues note.To investigate,they looked at 4, 589 fifthgraders participating in the Children's Lifestyle and Schoolperformance Study, 875 (19.1 percent) of whom had failed an elementary literacy assessment. The better a student's eating habits based on several measures of diet quality,including adequacy and variety, the less likely he or she was to have failed the test, the researchers found,even after they adjusted the data for the effects of parental income and education, school and sex.Eating plenty of fruit and vegetables, and getting fewer calories from fat, was also associated with a lower risk of failing the test. To date, Veugelers and his team say, most research on diet and school performance has focused on the importance of eating breakfast, as well as the ill effects of hunger and malnutrition . "This study extends current knowledge in this area by demonstrating the independent importance of overall diet quality to academic performance.We should not only realize the importance of children's nutrition at breakfast but also that throughout the day," the researchers conclude. Another research from the UK is suggesting that children's diets in the preschool years affects how they perform at school later on.The researchers from the Institute of Education, at the University of London say in fact that what children were eating in those days before primary school has more of an effect than the chicken nuggets they ate at lunchtime.The researchers say they have found that children who ate a diet of "junk food" at the age of three, made less progress in school between the ages of six and ten.They say children's diet at later ages appears to have less impact on their school attainment. .It can be implied from the passage that _ . | [

Another school day begins, and we all wish we could have just one extra hour of sleep. For lucky high school students in England, they're now going to reset their alarm and get an extra hour of sleep. Instead of starting school at 9 am, students will begin the academic day at 10 am. This is part of a huge study by Oxford University. The experiment will see whether later classes can improve exam results. More than 100 schools across England will join the four-year experiment, which includes tens of thousands of students. It is based on(...) scientific evidence(; )that teenagers are out of step with traditional school hours. "We know that something funny happens when you're a teenager," lead sleep researcher Colin Epsie told The Telegraph. "Your parents think it's because you're lazy and everything would be OK if you could get to sleep earlier. But science is telling us that teenagers need to sleep more in the mornings." A similar experiment in 2009 saw an improvement of 19 percent in exam scores for major subjects - such as math and science. Teenagers' sleep cycles, on average, begin two hours after adults. Neuroscientists say teens have a built-in clock, which makes them more likely to go to sleep around midnight. As well as not feeling fully awake until between 9 am and 10 am. This body clock stays until the age of 19 for females and 21 for males. Schools are places for learning, as well as education laboratories - finding out the best ways to learn and increase knowledge.

This factor is exercise.In the cities it is often faster to walk short distances than to wait for a bus.Even taking public transportation often requires some walking.Smaller apartment houses have no elevators ,and so people must climb stairs.City people can usually walk to local supermarkets.

mmlu_train_44636 | Rene Descartes' explanation of pain has long been acknowledged in medicine. He proposed that pain is a purely physical phenomenon - that tissue injury makes specific nerves send a signal to the brain, causing the mind to notice pain. The phenomenon, he said, is like pulling on a rope to ring a bell in the brain. It is hard to overstate how deeply fixed this account has become. In medicine, doctors see pain in Descartes' terms-- as a physical process, a sign of tissue injury. The limitations of this explanation, however, have been apparent for some time, since people with obvious injuries sometimes report feeling no pain at all. Later, researchers proposed that Descartes' model be replaced with what they called the gate control theory of pain. They argued that before pain signals reach the brain, they must first go through a gating mechanism in the spinal cord . In some cases, this imaginary gate could simply stop pain signals from getting to the brain. Their most _ suggestion was that what controlled the gate was not just signals from sensory nerves but also emotions and other "output" from the brain. They were saying that pulling on the rope need not make the bell ring. The bell itself--the mind-- could stop it. This theory led to a great deal of research into how such factors as mood, gender, and beliefs influence the experience of pain. In a British study, for example, researchers measured pain threshold and tolerance levels in 53 ballet dancers and 53 university students by using a common measurement: after immersing your hand in body-temperature water for two minutes to establish a baseline condition, you put your hand in a bowl of ice water and start a clock running. You mark the time when it begins to hurt: that is your pain threshold. Then you mark the time when it hurts too much to keep your hand in the water: that is your pain tolerance. The test is always stopped at 120 seconds, to prevent injury. The results were striking. On average female students reported pain at 16 seconds and pulled their hands out of the ice water at 37 seconds. Female dancers were almost three times as long on both counts. Men in both groups had a higher threshold and tolerance for pain, but the difference between male dancers and male nondancers was nearly as large. What explains that difference? Probably it has something to do with the psychology of ballet dancers--a group known for self-discipline, physical fitness, and competitiveness, as well as by a high rate of chronic injury. Their driven personalities and competitive culture evidently accustom them to pain. Other studies along these lines have shown that outgoing people have greater pain tolerance and that, with training, one can reduce one's sensitivity to pain. There is also striking evidence that very simple kinds of mental suggestion can have powerful effects on pain. In one study of 500 patients undergoing dental procedures, those who were given a placebo injection and promised that it would relieve their pain had the least discomfort-- not only less than the patients who got a placebo and were told nothing but also less than the patients who got actual drug without any promise that it would work. Today it is abundantly evident that the brain is actively involved in the experience of pain and is no more bell on a string. Today every medical textbook teaches the gate control theory as fact. There's a problem with it, though. It explains people who have injuries but feel no pain, but it doesn't explain the reverse, which is far more common-- the millions of people who experience chronic pain, such as back pain, with no signs of injury whatsoever. So where does the pain come from? _ . The author implies that the reason why the gate control was "amazing" was that it _ | [

mmlu_train_47122 | People are being lured onto Facebook with the promise of a fun, free service, and don't realize that they're paying for it by giving up loads of personal information. Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages. Most Facebook users don't realize this is happening. Even if they know what the company is up to, they still have no idea what they're paying for Facebook, because people don't really know what their personal details are worth. The biggest problem, however, is that the company keeps changing the rules. Early on, you could keep everything private. That was the great thing about Facebook--you could create your own little private network. Last year, the company changed its privacy rules so that many things--your city, your photo, your friends' names--were set, by default , to be shared with everyone on the Internet. According to Facebook's vice president Elliot Schrage, the company is simply making changes to improve its service, and if people don't share information, they have a "less satisfying experience." Some critics think this is more about Facebook looking to make more money. Its original business model, which involved selling ads and putting them at the side of the page, totally failed. Who wants to look at ads when they're online connecting with their friends? The privacy issue has already landed Facebook in hot water in Washington. In April, Senator Charles Schumer called on Facebook to change its privacy policy. He also urged the Commission to set guidelines for social-networking sites. "I think the senators rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them," Schrage admits. I suspect that whatever Facebook has done so far to invade our privacy, it's only the beginning,which is why I'm considering deactivating my account .

mmlu_train_21553 | Four out of ten women who diet end up heavier than when they started watching their waistline, a study revealed today. The research also showed that a large percentage of women start noticing the pounds creeping back on just 21 days after reaching their ideal weight. Yesterday, Dr Ian Campbell of the Jenny Craig weight management program said, 'In the UK 61.4 percent of adults are overweight or obese. Successful weight management requires a long-term commitment in order to lose weight successfully and for good. Dieting can be a real challenge so setting realistic goals and remaining focused on them is important. Otherwise as this research shows, women could end up heavier than when they started.' The "Food, Body, Mind" report was publicized by Jenny Craig who quizzed 2000 women aged between 18 and 65 who diet regularly on their attitudes, beliefs and behaviors around weight loss. Six in ten said they were currently on a diet and one in five women said they were on a continuous diet. It found the most common triggers to start dieting was seeing their reflection in the mirror, preparing for a summer holiday or unflattering photos posted on social networking sites. Other popular reasons include comments by friends or relatives or their other half. However, the study showed that one in ten give up within one day, while almost a fifth manage to make it to a week or more. The average is ten days. Many blamed pressure they put on themselves to lose weight too quickly for the weight gain, which leaves them with a bigger appetite than normal. Others blamed colleagues, who tuck into fatty lunches and snacks unaware of the effect it has on the dieter, while mothers' polishing off their children's leftovers was another common cause of weight gain.

Boaz Leupe,head of the company,says that e-Radiator works as a heating system and saves money.He explains that the energy is used twice-once to heat the home and once to cool the computer and that the users don't have to pay to cool their computers. Five homeowners in Holland are testing the heating system in their homes. "We pay for the computer using,so,in that way,homeowners get heating for free,"Boaz says.Jan Visser is one of the homeowners."If you use the computer more,the e-Radiator producers more heat,"he says,"It cannot provide enough heat if you don't use your computer often."But he is ready to try it.It's a great help for his family. The company says e-Radiators produce heat temperatures of up to 55degC.It says the system could save its users about 440 a year. The best title of the passage may be" _ ". | [

mmlu_train_63130 | Have you thanked your grandma today? You might want to consider it. A recent study found that kids live longer when a grandmother takes part in their daily lives. Most animals die soon after their childbearing years are over. Women, however, often live for many years after they stop having kids. To try to understand why, researchers from Finland looked at birth and death records of two communities from the 18th and 19th centuries, one in Finland and one in Canada. In these communities, 537 Finnish women and 3,290 Canadian women were grandmothers who had lived past the age of 50. For every decade they lived beyond 50, the researchers found that the women ended up with an average of two extra grandkids. It didn't matter what the differences in health or living conditions were between the two communities or from family to family. Grandchildren were also more likely to live into adulthood if their grandmothers were alive when they were born. If their grandmothers were younger than 60 at the time, that was even better. The study also found that women had children 2 to 3 years earlier if their own mothers were still alive at that time than those whose mothers had died. The researchers suggested that grandmothers have provided important assistance in raising their grandchildren for at least the past 200,000 years. As a result, they helped extend everyone's lifespan. So, don't take your grandma for granted! How did grandmothers help extend everyone's lifespan? | [
