What process allows plants to convert light energy into sugars and energy for food?
[ "respiration", "photosynthesis", "digestion", "glycolysis" ]
B
Chemical reactions are occurring all around you. Plants use sunlight to drive their photosynthetic process and produce energy. Cars and other vehicles burn gasoline in order to power their engines. Batteries use electrochemical reactions to produce energy and power many everyday devices. Many chemical reactions are going on inside you as well, especially during the digestion of food.

Learning to communicate in another language may be challenging, but it is also a very rewarding and enriching experience. It is the best passport to discovering another culture. Here are a few tips to help you make the most of the experience. Work at your own pace. Make the most of the time you have available to study. You will find you can learn more effectively if you study for half an hour every day, rather than try to do a whole unit in one sitting. Why not learn with someone else? It helps if you can learn with someone else. If you can persuade a friend or family member to study with you, it will give you extra motivation to keep working. Remember that you can go a long way with just a little language. Even if you feel unsure about your ability to form right sentences, you'll find that it is possible to communicate with just a few words. Above all, don't worry about getting things wrong: people will still be able to understand you. The more confidence you gain in communicating, the more fluent you'll become. Build up your vocabulary. A wide vocabulary is the key to successful language learning but don't try to learn too much at once. It's best to study frequently. Put words into sentences to fix them in mind, and come back to them later. Learning vocabulary in this way is usually very effective. And most of all, have fun! In the writer's opinion, it is better to study _ .

Hank owned a secondhand goods store. He often placed merchandise on the sidewalk, sometimes for short intervals, sometimes from 7 a.m. until 6 p.m. Pedestrians from time to time stopped and gathered to look at the merchandise. Fred had moved into an apartment which was 70 situated immediately above Hank's store; a street-level stairway entrance was located about 20 feet to the east. On several occasions, Fred had complained to Hank about the situation because not only were his view and peace of mind affected, but his travel on the sidewalk was made more difficult. Fred owned and managed a restaurant two blocks to the west of his apartment and made frequent trips back and forth. There was a back entrance to his apartment through a parking lot; this entrance was about 200 feet farther in walking distance from his restaurant. Once Fred complained to the police, whereupon Hank was arrested under a local ordinance which prohibited the placing of goods or merchandise on public sidewalks and imposed, as its sole sanction, a fine for its violation. One day, the sidewalk in front of Hank's store was unusually cluttered because he was cleaning and mopping the floor of his shop. Fred and his 15-year-old son, Steve, saw a bus they wished to take, and they raced down the stairs and onto the cluttered sidewalk in front of Hank's store, Fred in the lead. While dodging merchandise and people, Fred fell. Steve tripped over him and suffered a broken arm. Fred also suffered broken bones and was unable to attend to his duties for six weeks. If, prior to the day of his personal injuries, Fred had asserted a claim based on public nuisance for injunctive relief against Hank for his obstruction of the sidewalk in violation of the ordinance, the defense on which Hank would have most likely prevailed is that
[ "Fred consented to the obstruction by continuing to rent his apartment.", "the violation of the ordinance was not unreasonable.", "remedy of abatement by self-help was adequate.", "there was no claim for special damage" ]

DNA is the whole "map" of the human body. It is something that all human have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own. People have been trying to understand the human body for a long time. In 1860, Mr. Mendel discovered why we look the same as other people in our family. It is because of small things called "genes" in our body. In 1953, two scientists, Watson and Crick, found out that those small parts are really messages. They're written in the DNA with a special language. In 1961, another two scientists found the first "word" that they could understand in that language. It shows how DNA tells the cell to build its parts. So far, scientists have found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one "word" means, we can help to save people from several illnesses. So the more we understand, the more doctors will be able to do. Most people hope that this will help to make better medicine and help sick people. Other people worry that when we learn more "words" and and find out more information, we will use it in the wrong way, just to make people more attractive, or stop sick people getting jobs. How can we help sick people if we understand more "words" in the DNA map?

You hear the comment all the time: the U.S. economy looks good by figures, but it doesn't feel good. Why doesn't ever-greater wealth promote ever-greater happiness? It is a question that dates at least to the appearance in 1958 ofThe Wealthy Society by John Kenneth Galbraith, who died recently at 97. The Wealthy Societyis a modern classic because it helped describe a new moment in the human condition. For most of history, "hunger, sickness, and cold" threatened nearly everyone, Galbraith wrote. "Poverty was found everywhere in that world. Obviously it is not of ours." After World War II, the fear of another Great Depression gave way to an economic growth. In the 1930s unemployment had averaged 18.2 percent; in the 1950s it was 4.5 percent. To Galbraith, materialism had gone mad and would cause discontent. Through advertising, companies conditioned consumers to buy things they didn't really want or need. Because so much spending was artificial, it would be unsatisfying. Meanwhile, government spending that would make everyone better off was being cut down because people wrongly considered government only as "a necessary bad." It's often said that only the rich are getting ahead; everyone else is standing still or falling behind. Well, there are many undeserving rich -- overpaid chief managers, for instance. But over any meaningful period, most people's incomes are increasing. From 1995 to 2004, people feel "squeezed" because their rising incomes often don't satisfy their rising wants -- for bigger homes, more health care, more education, and faster Internet connections. The other great disappointment is that it has not got rid of insecurity. People regard job stability as part of their standard of living. As company unemployment increased, that part has gradually become weaker. More workers fear they've become " _ ," as Louis Uchitelle puts it in his book by the same name. Because so much previous suffering and social conflict resulted from poverty, the arrival of widespread wealth suggestedutopian possibilities. Up to a point, wealth succeeds. There is much less physical suffering than before. People are better off. Unfortunately, wealth also creates new complaints. Advanced societies need economic growth to satisfy the multiplying wants of their citizens. But the search for growth cause new anxieties and economic conflicts that disturb the social order. Wealth sets free the individual, promising that everyone can choose a unique way to self-accomplishment. But the promise is so unreasonable that it leads to many disappointments and sometimes inspires choices that have anti-social consequences, including family breakdown. Figures indicate that happiness has not risen with incomes. Should we be surprised? Not really. We've simply confirmed an old truth: the seeking of wealth does not always end with happiness. The Wealthy Society is a book _ .

Shundagarh is a village on India's east-facing coast.It is a village of simple mud and grass houses built on the beach just above the waterline.The Khadra Hills rise immediately behind the village,to a height of one hundred and fifty meters.A simple,good-hearted old man,whose name was Jalpur,farmed two small fields on the very edge of these hills.From his fields he could see the fishing boats that travelled up and down the coast.He could see the children playing on the sands;their mothers washing clothes on the flat stones where the Shiva River flowed into the sea;and their fathers landing the latest catch or repairing nets and telling stories that had no end. All Jalpur owned in the world were the clothes he wore day in and day out,the miserable hut that he slept in at night,a few tools and cooking pots--and his fields.The corn that he grew was all that made life possible.If the weather was kind and the harvest was good,Jalpur could live happily enough--not well,but happily.When the sun was fierce,and there was little or no rain,then he came close to the line between life and death. Last year the weather had been so kind,and the harvest promised to be so good,that Jalpur had been wondering whether he could sell all that he had and live with his son farther up the coast.He had been thinking about doing this for some years.It was his dearest wish to spend his last days with his son and his wife.But he would go only if he could give;he would not go if it meant taking food out of the mouths of his grandchildren.He would rather die hungry than do this. On the day when Jalpur decided that he would harvest his corn,sell it,and move up the coast,he looked out to sea and saw a huge wave,several kilometers out,advancing on the coast and on the village of Shundagarh.Within ten minutes everyone in Shundagarh would be drowned.Jalpur would have shouted,but the people were too far away to hear.He would have run down the hill,but he was too old to run.He was prepared to do anything to save the people of Shundagarh,so he did the only thing that he could do: he set fire to his corn.In a matter of seconds the flames were rising high and smoke was rising higher.Within a minute the people of Shundagarh were racing up the hill to see what had happened.There,in the middle of his blackened cornfield,they found Jalpur;and there they buried him. On his grave,they wrote the words: Here lies Jalpur,a man who gave,living: a man who died,giving. Which of the following could Jalpur NOT see from his Fields?

Happy birthday! Do birthday really make people happy? Of course they do. _ Birthdays celebrate the day when we were born. Besides, that extra candle on the cake suggests another year of growth and maturity --or so we hope.We all like to imagine that we are getting wiser and not just older.Most of us enjoy seeing the wonder of growth in others, as well.For instance, seeing our children develop and learn new things makes us feel proud.For Americans, like people in most cultures, growing up is a wonderful process.But growing old? _ That is a different story. Growing old is not exactly for people in youth-oriented American culture.Most Americans like to look young, act young and feel young. As the old saying goes, "You're young as you feel." Older people joke about how many years young they are, rather than how many years old.People in some countries value the aged as a source of experience and wisdom.But Americans seem to favor those who are young, or at least "young at heart". _ Economically, "senior citizens" often try just to get by.Retirement at the age of 65 brings a sharp decrease in personal income.Social security benefits usually cannot make up the difference.Older people may suffer from poor nutrition , medical care, and housing. Some even have the experience of age discrimination . American sociologist Pat Moore once dressed up like an older person and wandered city streets.She was often treated rudely--even cheated and robbed.However, dressed as a young person, she received much more respect. Unfortunately, the elderly population in America is increasing fast.Why?

Cats are the most popular pets among Americans. So it is not surprising there are many expressions about cats. Do you know any of them? Now let me introduce some to you. Some cats like to catch small birds, like canaries. If someone looks very proud or satisfied with himself, we say he looks like the cat that ate the canary. Sometimes, a cat likes to play with a small animal it catches. So if you play cat and mouse with someone, you change between different kinds of behavior when dealing with another person. For example, a child might offer something sweet to her little brother, and then take it away when reaches for it. A cat will often catch a small animal and present it to its owner. The saying that looks like something the cat dragged in describes something in bad condition. A fat cat is a person with a lot of money. There are many other expressions about cats in America.

But any space range, in fact, is related to a certain time range, this time range is long and short, and in this time range, place names are associated with many things and factors other than place names. Therefore, in addition to the original intention, place names also have their historical, cultural, social, national and other aspects of significance.

Children who spend more time outdoors may have a lower risk of becoming nearsighted, new research suggests. In the study, researchers looked at about 1,900 schoolchildren. The scientists found that the kids who had been instructed to spend more time outdoors over three years were 23 percent less likely to develop nearsightedness during this time than those who had not been instructed to spend more time outdoors. Moreover, among the kids who did become nearsighted during the study, the degree to which their eyesight worsened was slightly smaller among those who spent more time outdoors. The researchers selected six schools and required the children, whose average age was 7 at the start of the study, to attend one additional 60-minute class of outdoor activities during each school day for three years. The parents of these children were also encouraged to engage their children in outdoor activities after school, especially during weekends and holidays. The other half of the children, from another six schools, continued their usual activity patterns. Afterthree years, 30.4 percent of the kids in the intervention group had become nearsighted, compared with 38.5 percent of the kids in the other group. It is not clear exactly why spending more time outside would benefit children's eyesight, the researchers said. However, some research has suggested that the higher levels of light intensity found outdoors may increase the release of the chemical dopamine of the eye. In turn, dopamine is known to restrain the type of growth in the eye that is associated with nearsightedness. Based on the new results, the researchers recommend that children spend more time outdoors because of the potential benefits to their eyesight. However, it's important to protect kids' skin and eyes from UV light, which can be damaging. Which can serve as the best title for the passage?

There is an old Chinese tale about a woman whose only son died. Sadly, she went to the holy man and asked, "What magical things do you have to bring my son back to life?" Instead of sending her away or reasoning with her, he said to her, "Fetch me a mustard seed from a home that has never known sadness. We will use it to drive the sadness out of your life." The woman happily went off at once in search of that magical mustard seed. She first came to a splendid house, knocked at the door and said, "I am looking for a home that has never known sadness. Is it such a place? It is very important to me." They told her "You've certainly come to the wrong place" and began to describe all the tragic things that had happened to them recently. The woman said to herself, "I have had misfortune of my own. Who is able to help these poor, unfortunate people?" She stayed to comfort them, and then went on in search of a home that had never known sadness. But wherever she went, she found one tale after another of sadness and misfortune.

Humans have an internal clock that regulates the beating of our heart, the pace of our breathing, the discharge of chemicals within our bloodstream, and many other bodily functions. Time is something from which we can't escape. Even if we ignore it, it's still going by, ticking away, second by second, minute by minute, hour by hour. So the main issue in using your time well is, "Who's in charge?" We can allow time to slip by and let it be our enemy. Or we can take control of it and make it our _ . By taking control of how you spend your time, you'll increase your chances of becoming a more successful student. Perhaps more importantly, the better you are at managing the time you devote to your studies, the more time you'll have to spend on your outside interests. The aim of time management is not to schedule every moment so we become slaves of a timetable that governs every waking moment of the day. Instead, the aim is to make informed choices as to how we use our time. Rather than letting the day go by, largely without our awareness, what we are going to discuss next can make us better able to control time for our own purposes.

A baby carrier is like a backpack for carrying a baby. Ann Moore introduced the idea of a baby carrier to American people nearly 50 years ago. Ann spent two years in Africa in the early 1960s. She worked as a nurse there. Ann saw babies wrapped in bright cloth tied to their mothers' backs. The babies snuggled close to their mothers, and the mothers could use their hands to do other things. In 1964, Ann had her own baby. She tried making a carrier like the one African mothers used. The carrier was like a backpack. Everywhere Ann went with her baby in the carrier, people asked, "Where can I buy one?" In 1965, Ann and her mother began to sell handmade carriers. Ann received a patent for the baby carrier in 1969. By that time, the baby carrier had leg holes and straps that could be made longer or shorter. It could also be worn on the back or front. By 1979, the baby carriers were made in a factory. These baby carriers cost less to make and more than 25,000 were sold every month. When Ann made her first baby carrier, she just wanted to keep her baby close and still have her hands free to do other things. Now all over the world babies ride in baby carriers, close to their parents, safe and happy. ,. What's the passage mainly about?

D
If we do not try to raise the income of the low-income people, the society will be unstable; if the private economy is not allowed to get a return, the economy will not go up. In the face of the dilemma of income and distribution, it is correct to advocate that efficiency is priority and giving consideration to fairness. If we listen to the proposition that fairness is priority and give consideration to efficiency, China's economy will return to the era of neither efficiency nor fairness.

DNA is a substance that makes up genes. Everything alive has genes. Plants have genes. Animals have genes. You have genes. Genes are the basic units of heredity . Heredity means all the characteristics you inherit from your parents. You get your genes from your parents. You inherit half of your genes from your mother. You inherit half of your genes from your father. Genes are a kind of code. A tree's genes tell what shape its leaves will be. A cat's genes tell what color1 its fur will be. Your genes tell what color1 your eyes will be. Your genes tell what color1 your hair will be. Everything about you comes from the code in your genes. Genes line up on strands called chromosomes in cells. Everything alive is made up of cells. Chromosomes are in the center, or nucleus, of cells. An Austrian monk named Gregor Mendel first saw inherited patterns in pea plants. He experimented with pea plants in the 1860s. One of the things, or traits , Mendel studied was what makes some pea plants tall and some short. He said that the traits must come from units of heredity passed from the parent plants. These units were called genes. In the mid-1900s, scientists discovered that genes are made of DNA. In the 1970s, scientists learned how to change DNA with genetic engineering. Scientists also learned that problems with certain genes cause diseases. Muscular dystrophy, cystic fibrosis, and hemophilia are some genetic diseases--diseases caused by problems in genes. Today, scientists are looking for ways to cure genetic diseases by _ genes through a process called gene therapy. In the last sentence, the word "altering" can best be replaced by _ .

The struggle to "have it all" leaves many mothers giving up their health and hobbies. But dads have more time to spare according to a research, with just 55 per cent saying they lose sleep and regular exercise compared with 71 percent of mums. Twice as many mothers as fathers complained that they did not spend enough time relaxing, with almost half of mums spending less than two hours a week with friends. And more than a third miss out on hobbies and interests because they are too busy. In spite of changing roles in the family, women are still responsible for most of the child care. Nearly a third spend more than 10 hours a week caring for their children, compared with just one in ten fathers. More mums than dads also say housework and tiredness stop them achieving their goals. But the research also shows mums gain a sense of achievement from finishing the housework, getting their children to school on time or sitting down to a family dinner. The research underlines the fact that women feel under pressure to succeed in all areas of their lives. As Nick Booth, a marketing director put, "They are pushing themselves too hard and are in danger of burning out. We'd encourage anyone to take time out for themselves. Having your own interests and hobbies and ensuring you get enough sleep is hugely important. Other parts of your life, including work and family life, improve as a result." The Olympian and mother Jo Pavey admitted balancing career, family and personal time can be a struggle. Jo, 41, became the oldest female gold medalist at the European Championship last year - but regards her children as her biggest achievement.

About ten men in every hundred suffer from colour blindness in some way. Women are luckier. Only about one in two hundred is affected in this matter. So some people say it is safer to be driven by women. There are different forms of colour blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green--a strange world indeed. Colour blindness in humans is a strange thing to explain. In our eyes there are millions of very small things called "cones". These help us to see in a bright light and to tell differences between colours. There are also millions of "rods", but these are used for seeing when it is nearly dark. They show us shapes but no colour. Some insects have favourite colours. Mosquitoes like blue but do not like yellow. A red light will not attract insects, but a blue lamp will. In a similar way humans also have favourite colours. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colours by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colours around us. Why do some people say it is safer to be driven by women?

He looked at the beautiful flowers, imagining how happy he could be if he lived in such a beautiful place. Then ,suddenly he found the old gardener was blind. He was very surprised about this and asked,"You can't see these flowers. "Why are you busy taking care of them every day?" The old man smiled and said ,"I can tell you four reasons. First, I was a gardener when I was young, and I really like this job. Second, although I can't see these flowers, I can touch them. Third, I can smell the sweetness of them. As to the last one, that's you." "Me? But you don't know me."said the young man. "Yeah, it's true that I don't know you. But I know that flowers are angels that everybody knows.

A
It is generally believed that the sword mastodon migrated to South America from North America. The sword mastodon is characterized by sharp sword-shaped incisors, short jaws, protuberant crowns of molars, 7 to 8 dental plates, and milky protuberances, hence the name. The tooth structure of the sword mastodon is more complex, which indicates that it can eat grass. There is evidence in many parts of South America that prehistoric humans captured sword mastodon. It can be inferred that the extinction of sword mastodon may be closely related to the overhunting of human beings.

French doctors and American scientists have reported doing an operation in which the doctor was outside the operating room. This kind of operation is known as robotic operation. Doctor Marescaux did the operation in an office in New York City last month, while a sixty-eight-year-old woman patient was in a hospital in Strasbourg, France. A doctor in Strasbourg got the patient ready. He placed medical tools and a small video camera in her stomach area. Doctor Marescaux in New York watched the patient on a video screen. Then he used the computer to send messages to the robot machine. The robot moved the tools that cut the woman's gallbladder away. The woman got well soon after the operation and left the hospital two days later. Experts say the main problem with such a robotic operation is based on high-speed telecommunications between the doctor and the robot. Technology must be able to send a doctor's order to a robot to move the tools quickly. Experts also say a successful robotic operation will improve an operation. For example, the robot can make much smaller movements than a person can. A robot machine can turn tools in ways that a doctor's hand cannot. Doctors say such a robotic operation will make possible safer and better operations in the future. They say it will improve doctor training. It will also mean that doctors could do an operation on people in dangerous places far away. And it could mean that people could have operations done by top doctors without having to travel to the city where doctors work. Robotic operation means " _ ".

Switzerland is one of the most developed countries in Europe. It is famous as one of the cleanest countries in the world. The Swiss think that recycling is very important. The government has made laws which require everyone to recycle. In 1998, the Swiss government passed a law which says that people can not throw away any electronic machines. Instead, people are told to bring old ones, such as televisions, computers and fridges, to special centers when they didn't need them. Many parts of the old machines are reused, and only the parts that can't be used are thrown away. The government also charges a rubbish bag tax . If people want their rubbish to be collected, they must buy yellow stickers and put them on their rubbish bags. In 2003, 47% of all rubbish in the cities was recycled. This included 70% of paper, 95%of glass, 71%of plastic bottles and 85--90%of cans. Until recently, people could get a small amount of money when they recycled their bottles. Recycling has become a daily habit for the Swiss. Everyone should learn from the Swiss, and our country will be clean like Switzerland. The best title of the article is _ .

Soup on my nose, a nearly spilled glass of wine and chocolate down my white blouse, as blind dates suggest, this was a really messy one. I have never made so much noise with plates and glasses, nor had I dined with a never-before-met companion. This blind date was quite different: we could see nothing. "Put your left hand on my shoulder, and then we'll take small steps forward," said Michael, the visually impaired server, in an East London accent. We three felt our way carefully bumping past heavy curtains before being arranged at the dining table, where we would eat and drink three completely secret and unseen courses. Welcome to Alchemy in the Dark, Hong Kong's first full-time restaurant in total darkness. Upon arrival, diners briefly tell the chef on their allergies , lock away their mobile phones and enter the windowless restaurant, which can seat 25. When the meal is over, the contents of the delicious menu are shown --- often to the diners' surprise. "This is definitely duck," my friend said, while eating chicken. "This soup," I declared, "is carrot and coriander." Even the too-close smell did not reveal the real tomato and cumin flavors. Dining in the dark changes everything: the sense of smell is heightened, manners go out of the window ----using your hands to feel around the plate becomes normal--- and there is a strange thrill in being able to ignore your facial expressions. Best of all? You don't have to spend hours beforehand wondering what to wear. Alchemy in the Dark is at 16 Arbuthnot Road, Central, (tel: 6821 2801) and is open Monday to Saturday, from 7pm to 11pm. Reservations are required. A three-course meal with wine pairing costs HK$700 per person. Five per cent of all profits go to the Hong Kong Society for the Blind. How did the author and her companion arrive at their dining table?

My cat Toto is aging,and as she ages,her body is failing her.Mentally,she seems sharp,but after nearly sixteen years,Toto's hips are causing her obvious trouble.In fact,they make it so that she can't use a litter box effectively.She tries to squat ,but mostly she just pisses out the back end of the box. I spent the summer working with my vet to find things to help Toto,but nothing works.Since we can't stand the smell of cat urine in the house,two weeks ago I took drastic measures.I _ Toto outside.(She gets to come in while I work,but I put her out for 80%of the day and night.) Because Toto now lives outside,she eats and drinks outside.I' ve set up a heating pad on the porch.and given her own food and water area nearby.She seems perfectly content with this arrangement except when she's out of food,or she wants to be petted. Strangely enough,she's been out of food a lot lately."I think another cat is eating Toto's food."I told Kris when I first noticed how quickly she was going through her bowl. "Actually,"I said a couple of days later,"maybe it's a dog.Whoever is eating Toto's food keeps knocking the bowl over." But a few days after that,I realized that the food thief probably wasn't even a dog.Whatever the critter was,it was messy. Every morning,Toto's water dish was filled with mud.The food bowl was tipped over and the porch scattered with mud and debris ."I' ll bet it's a coon ,"I told Kris.Though we live in a residential neighborhood not far from Portland,we' ve seen plenty of raccoons in the six years since we moved in. Today I got to see the cat-food thievery first-hand.Turns out it's not one raccoon-it's a family of four.I was lucky enough to have my camera handy as they performed their daring raid:My favorite part of this video is how Toto simply sits on her heating pad and watches the raccoons eat her food.She isn't bothered at all.

We take it for granted that with memory we can remember most of things which happened in our life. But it is difficult to imagine what life would be like without memory. The meanings of thousands of everyday perceptions , the basis for the decisions we make, and the roots of our habits and skills are to be found in our past experiences, which are brought into the present by memory. Memory can be defined as the ability to keep information available for later use. It not only includes "remembering" things like arithmetic or historical facts, but also involves any change in the way an animal typically behaves. Memory is involved when a rat gives up eating grain because he has sniffed something suspicious in the grain pile. Memory exists not only in humans and animals but also in some physical objects and machines. Computers, for example, contain devices for storing data for later use. It is interesting to compare the memory storage capacity of a computer with that of a human being. The instant access memory of a large computer may hold up to 100,000 "words"--strings of alphabetic or numerical characters--ready for instant use. An average U.S. teenager probably recognizes the meaning of about 1000,000 words of English. However, this is but a part of the total amount of information that the teenager has stored. Consider, for example, the number of faces and places that the teenager can recognize on sight. The use of words is the basis of the advanced problem solving intelligence of human beings. A large part of a person's memory is in terms of words and combinations of words. But while language greatly expands the number and the kind of things a person can remember, it also requires a huge memory capacity. It may well be this capacity that distinguishes humans, setting them apart from other animals. What is the major characteristic of man's memory capacity according to the author?
[ "It can be expanded by language.", "It can remember all the combined words.", "It may keep all the information in the past.", "It may change what has been stored in it." ]

More and more birds are flying to settle at Qinghai Lake, one of the highest inland lakes in China, thanks to the protection efforts of local governments. Covering an area of over 4,000 square kilometers, Qinghai Lake is also the country's biggest salt-water lake. Located in Northwest China's Qinghai Province, the lake is famous for the two islands at its northwest point--Cormorant Island and Egg Island. The two islands have plenty of floating grass and various schools of fish, offering rich food sources for birds. The islands have become a paradise for different kinds of groups of birds and have been called 'Bird Islands'. Each March and April, when ice and snow covering the Qinghai-Tibet Plateau starts to melt, over 20 kinds of birds fly to the Bird Islands to lay eggs. During the months, flocks of birds cover the whole sky over the islands and birds eggs can be found everywhere. Visitors can hear the singing of birds from miles away. These have become a world famous symbol of the lake. To protect this paradise for birds and support calls for ecological protection, China set up the Qinghai Lake Natural Protection Zone at the end of 1997. Meanwhile, the State has pointed out the Bird Islands and Spring Bay of the Qinghai Lake as central protection zones. Inspection officials and management employees often patrol the lake, improving local residents' knowledge of related laws and spreading knowledge about animal protection to visitors. They are making great efforts to call on people to love and protect the birds. At the same time, they have built special fences around the island area, to prevent wolves, foxes and other carnivorous animals, as well as illegal hunters from breaking up the birds' nest-building, egg-laying and breeding. As a result, more and more birds are coming to the islands for sheltering and breeding. Why are more and more birds coming to the biggest salt-water lake in the Great Northwest?

A
Columnist: On average, about 70 percent of the profit from tourism in developing countries goes to foreign owners of tourist businesses. In general, as a country becomes a more established tourist destination, the proportion of revenues exported in this way increases. However, tourists can counteract this effect by obtaining accommodations and other services directly from local people.

There are many things we need to know that we do not learn at school. For example, if we want to use our money wisely, we need to shop carefully. We need to know how to compare the prices of things in different shops. We need to be able to compare the quality of different brands . We need to know how to make a choice when we shop. Knowing how to make such choices is a "life skill", and we need these skills if we are to live useful and happy lives. Some of these choices are small. For example, will I take an apple for lunch or a pear? Will I go to school by bus or on foot? Will I wear the red T-shirt or the blue one to the movies? Other choices are more important. For example, will I eat healthy food for lunch or will eat junk food because it is tastier? Will I work hard in all my classes or will I only work hard in the classes I enjoy? We make choices like this every day. We have to realize that the choices we make can affect the rest of our lives. Just as importantly, our choices can also affect other people.

The next time you eat a piece of chocolate, be sure to enjoy it, because according to two of the world's largest chocolate makers--Mars Inc and Barry Callebaut, the treat may soon be in short supply. The problem? We are consuming the candy at a faster pace than farmers can grow cocoa. The manufacturers say that in 2013, people consumed 70,000 tons more cocoa than was produced. Experts say that this is the worst supply-demand imbalance they have experienced in more than 50 years. Parts of the reason for the condition is the large reduction in supply, caused by a continuous drought in the west African countries of Ivory Coast and Ghana, where more than 70 percent of the world's cocoa is produced. Additionally, a certain disease known as frosty pod has destroyed 30 to 40 percent of global cocoa production. As a result, many farmers have turned to more profitable and easier grown crops like corn. This means that even if conditions improve, cocoa production may never get back to normal. Meanwhile, the world is only getting hungrier for chocolate. The biggest increase in demand is from the residents of emerging market countries like India. Though their consumption is nowhere close to the amount European devour, their newly acquired amount for the treat , is making a huge dent in an already tight market. There is also the growing desire for dark chocolate, which contains more than 70 percent cocoa compared to normal chocolates. Experts believe that if consumption continue at this pace, cocoa deficits could swell to one million tons by 2020 and to an even more worrisome, two million tons, by 2030. Not surprisingly, cocoa prices have risen by 60% since 2012, a cost that manufacturers have offset by raising the prices of everyone's favorite candy. As the situation worsens, the price of chocolate can only rise--so be sure to enjoy piece of the sweet treat, like it is your last! Where has the demand of chocolate been increasing greatly according to the passage?

I spent my last vacation trekking in Nepal, a small country in the Himalaya Mountains of Asia. On a trekking vacation, you walk for long distances through the mountains. There are very few roads in Nepal, so trekking is the best way to travel. It's best if you hire a guide . The guides know the best paths to take and they also help trekkers with their bags. Our guide even cooked our food for us. Every day, we trekked for about four hours before lunch, and about two hours in the afternoon. At the end of the day's trek, we sat around a campfire and talked about the things we saw. Then we went to sleep in large tents. Every morning, our guide brought breakfast to our tent. It was great.

Studies have shown that cosmic rays entering thunderclouds ionize the air in thunderclouds, which in turn produces many suspended free electrons around. The electric field already in the clouds makes the free electrons carry higher energy. When existing electrons in the air collide with water molecules, more electrons are released, which the researchers call a high-energy snowstorm, resulting in a escape collapse, a discharge process known as lightning.

When you get in your car, you reach for it. When you're at work, you take a break to have a moment alone with it. When you get into a lift, you play with it. Cigarette? Cup of coffee? No, it's the third most addictive thing in modem life, the cell phone. And experts say it is becoming more difficult for many people to _ their longing to hug it more tightly than most of their personal relationships. The costs are becoming more and more evident, and I don't mean just the monthly bill. Dr. Chris Knippers, a counselor at the Betty ford Center in Southern California, reports that the overuse of cell phones has become a social problem not much different from other harmful addictions: a barrier to one-on-one personal contact, and an escape from reality. Sounds extreme, but we' ve all witnessed the evidence: The person at a restaurant who talks on the phone through an entire meal, ignoring his kids around the table; the woman who talks on the phone in the car, ignoring her husband; the teen who texts messages all the way home from school, avoiding contact with kids all around him. Jim Williams, an industrial sociologist based in Massachusetts, notes that cell - phone addiction is part of a set of symptoms in a widening gulf of personal separation. He points to a study by Duke University researchers that found one-quarter of Americans say they have no one to discuss their most important personal business with. Despite the growing use of phones, e - mail and instant messaging, in other words, Williams says studies show that we don't have as many friends as our parents. " Just as more information has led to less wisdom, more acquaintances via the Internet and cell phones have produced fewer friends," he says. If the cell phone has truly had these effects, it's because it has become very widespread. Consider that in 1987, there were only l million cell phones in use. Today, something like 300 million Americans carry them. They far outnumber wired phones in the United States. The example of a woman talking on the phone in the car supports the idea that _ .
