Elderly adults who regularly drink green tea may stay more agile (敏捷的) and independent than their peers over time, according to a Japanese study that covered thousands of people.
Green tea contains antioxidant chemicals (抗氧化化学物质) that may help stop the cell damage that can lead to disease.Researchers have been studying green tea’s effect on everything from cholesterol (胆固醇) to the risk of certain cancers，with mixed results so far.
They found those who drank the most green tea were the least likely to develop “functional disability”，or problems with daily activities or basic needs，such as dressing or bathing.
Specifically，almost 13 percent of adults who drank less than a cup of green tea per day became functionally disabled，compared with just over 7 percent of people who drank at least five cups a day.
The study did not prove that green tea alone kept people agile as they grew older.Green tea lovers generally had healthier diets，including more fish，vegetables and fruit，as well as more education，lower smoking rates，fewer heart attacks and strokes，and greater mental sharpness.They also tended to be more socially active and have more friends and family to rely on.But even with those factors accounted for，green tea itself was tied to a tower disability risk，the researchers said.
People who drank at least five cups a day were onethird less likely to develop disabilities than those who had less than a cup per day.Those people who averaged three or four cups a day had a 25 percent lower risk.
Although it’s not clear how green tea might offer a buffer (缓冲) against disabilities，lead researcher Yasutake Tomata did note that one recent study found green tea extracts (提取物) seem to increase leg muscle strength in older women.
While green tea and its extracts are considered safe in small amounts，they do contain caffeine and small amounts of vitamin K，which means it could affect drugs that prevent blood clotting (凝固)．What does the underlined word “peers” mean in the first paragraph?
| A．Fathers. |
| B．Brothers. |
| C．People of the same age. |
| D．People living in the same neighborhood. |

| B．Those who often drink green tea can’t develop “functional disability”． |
| C．“Functional disability” is related to problems with daily activities or basic needs. |
| D．People who drink at least five cups a day are not likely to become functionally disabled. |

When you have a question about something, where do you go? For many people the answer is simple as they can go online to a search engine like Google or Yahoo. But what about people in rural or underdeveloped areas who may have no way to get on the Internet?
A business and international development professor in California, Rose Shuman, found an answer for them: Question Box. Question Box is a service that provid
es answers---free of charge--- for people who cannot search the Internet directly. The users of Questions Box might be those who might not be 
able to read, or simply have no access to the Internet.
Question Box began three years ago in India. People used a metal call box with a push-to-talk button to connect a live operator. Rose Schuman explained,” You just need to push a big green button on the box which will connect you directly to our operators who are sitting in front of computers, and speak your language. You can ask them any sort of question you want, and they’ll look it up in English or in Hindi, or whatever the main language is, and translate the answer back for you.”
The service is currently offered in two villages. The latest version of the box uses mobile phone technology, and solar panels in case the electrical power fails. Rose Shuman says the aim was to make the box as easy as possible for users, “It is very efficient (效率高的). Rather than try to bring a lot of difficulties to them and expect them to spend a lot of time to learn how to use the Internet, the idea was to make a technology that even Grandma could use.”
In April 2009, Question Box was introduced to Uganda. Forty community workers with mobile phones connected villagers to call center operators in Kampala. The community workers went around telling people about the service. They wore T-shirts that said “Ask me.” But Internet service in Uganda proved slow and undependable. So Question Box teamed up with a local technology company to store information on a local server. That way, the researchers in Kampala could quickly search the database for answers. The best title for the passage is __________.
| A．Question Box ----taking the place of the Internet |
| B．Needing an answer? ----asking Question Box |
| C．Question Box ----A great invention in the world |
D．Rose Shuman----- A professor helping the poor |
In Rose Schuman’s opinion, the greatest advantage of Question Box is that______.
| A．It is the most advanced in the world |
| B．It is more convenient to carry. |
| C．It is much easier to use |
| D．it saves much more energy |
The underlined word “them” in the fourth paragraph refers to______.
| A．the users | B．the operators |
| C．the researchers | D．Question Box workers |
What can we know from the passage?
| A．Question Box costs the users much less than the Internet. |
| B．Question Box operators can look for information in any language. |
| C．Question Box is more efficient in solving problems in underdeveloped areas. |
| D．Question Box can work without the help of the Internet in Uganda. |
In most people’s opinion, the tiger is not an animal that we would ordinarily think of as being chicken. However, one tiger, which lives in an English zoo, turned out to be more cowardly( 胆小的) than his keepers could ever have imagined.
Tanvir, a two-year-old Bengal tiger, got stuck at the top of a new 5m-high activity tower in the zoo, after climbing it for the first time.
The wooden tower had been designed to provide mental exercise for Tanvir by testing his ability of dealing with troublesome situations, but after climbing it in just a few seconds, he lost his courage when it came to coming back down. Tanvir went on to spend nearly two days at the top of the tower trying to collect the courage to attempt to get down.
A spokesperson for the zoo said that several days before Tanvir had taken half an hour to get down a lower tower only 1.5m high, and the taller tower had clearly been too much challenging for him.
“Every time he got to the edge, he looked out, put a paw over, and thought, ‘no, I cannot make it!’”laughed Samantha Cordrey, Tanvir’s keeper. In the end Tanvir’s hunger defeated his fear, and after almost 48 hours he made his way down. Burying himself in a big meal just like a hungry pig, Tanvir seemed to forget such a shameful experience for a while.
It appears that his experience would not be the worst in Tanvir’s life if he continued to act like a chicken. It is not known whether he will take courage to go back up his exercise tower again.
The whole episode(插曲) only serves to show the difficulties faced by zoo staff in creating environments that will improve animals’ living ability in enclosed space.When speaking of Tanvir’s shameful experience, Samantha Cordrey might feel it was_____.
| A．funny | B．surprising | C．exciting | D．unbelievable |
What made Tanvir get down the 5m-high activity tower at last?
| A．The coldness of the weather. | B．The direction from his keepers. |
| C．The sufferings of being hungry | D．The fear of being alone |
Why d
oes the author say “this experience would not be the worst in Tanvir’s life if…”(Paragraph 6)?
| A．Because Tanvir’s keepers will design more difficult exercise for him. |
| B．Because Tanvir is so cowardly that he has little courage to meet greater challenges. |
| C．Because Tanvir’s bad health will bring him much trouble in practice. |
| D．Because Tanvir is always careless and often causes trouble by accident. |
The zoo designed the 5m-high activity tower to______.
| A．make Tanvir become brave |
| B．improve Tanvir’s performance skills |
| C．let tourists watch Tanvir better |
| D．improve Tanvir’s living ability |
A rainfores（雨林）is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16℃.Rainforests have a great effect on the world environment because they can take in（吸收） heat from the sun and adjust （调节）the climate. Without the forest cover, these areas would reflect more heat into the atmosphere，warming the rest of the world .Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters（灾害） all over the world.
In the past hundred years, humans have begun destroying rainforests in search of three major resources (资源): land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example，a lot of carbon dioxide(二氧化碳)in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit（受益）.
There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run （长远看）it actually reduces the world’ s wood supply.
Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in （在于）the world’s shrinking rainforests..．Rainforests can help to adjust the climate because they________.
| A．reflect（反射） more heat into the atmosphere |
| B．bring about high rainfall throughout the world |
| C．rarely cause the temperature to drop lower than 16℃ |
| D．reduce the effect of heat from the sun on the earth |
.．What does the word “this” underlined in the third paragraph refer to?
| A．We will lose much more than we can gain. |
| B．Humans have begun destroying rainforests. |
| C．People have a strong desire for resources. |
| D．Much carbon dioxide comes from burning rainforests. |
.What might be the best title for the text?
| A．How to Save Rainforests | B．How to Protect Nature |
| C．Rainforests and the Environment | D．Rainforests and Medical Development |
Remembering names is an important social skill. Here are some ways to master it.
Recite and repeat in conversation（谈话，交往）.
When you hear a person’s name, repeat it. Immediately say it to yourself several times without moving your lips. You could also repeat the name in a way that does not sound forced or artificial（矫揉造作的，不自然的）.
Ask the other person to recite and repeat.
You can let other people help you remember their names. After you’ve been introduced to someone，ask that person to spell the name and pronounce it correctly for you. Most people will be pleased by the effort（努力） you’re making to learn their names.
Admit you don’t know.
Admitting that you can’t remember someone’s name can actually make people relaxed. Most of them will feel sympathy if you say, “I’ m working to remember names better. Yours is right on the tip of my tongue. What is it again？”
Use associations（联络，联系）.
Link（联系） each person you meet with one thing you find interesting or unusual. For example, you could make a mental note：“Vicki Cheng — tall, black hair.” To reinforce (加强) your associations, write them on a small card as soon as possible.
Limit the number of new names you learn at one time.
When meeting a group of people, concentrate on（集中精力） remembering just two or three names. Free yourself from remembering everyone. Few of the people in mass introductions expect you to remember their names. Another way is to limit yourself to learning just first names. Last names can come later.
Go early.
Consider going early to conferences（会议）, parties and classes. Sometimes just a few people show up（到场） on time. That’s fewer names for you to remember. And as more people arrive, you can hear them being introduced to others — an automatic （无意识的）review for you..．How will most people feel when you try hard to remember their names?
| A．They will be moved. | B．They will be annoyed. |
| C．They will be delighted. | D．They will be discouraged. |
.If you can’t remember someone’s name, you may ________.
| A．tell him the truth | B．tell him a white lie |
| C．ask him for pity | D．ask others to help you |
.．When you meet a group of people, it is better to remember________.
| A．all their names | B．a couple of names first |
| C．just their last names | D．as many names as possible |
.．What does the text mainly tell us?
| A．Tips on an important social skill. | B．Importance of attending parties. |
| C．How to make use of associations. | D．How to recite and repeat names. |
People believe that climbing can do good to health. Where can you learn the skill of climbing then? If you think that you have to go to the mountains to learn how to climb, you’re wrong. Many Americans are learning to climb in city gyms(体育馆). Here，people are learning on special climbing walls. The climbing wall goes straight up and has small holding places for hands and feet.
How do people climb the wall? To climb，you need special shoes and a harness (保护带) around your chest to hold you. There are ropes(绳索)tied to your harness. The ropes hold you in place so that you don’t fall. A beginner’s wall is usually about 15 feet high, and you climb straight up. There are small pieces of metal that stick out for you to stand on and hold on to. Sometimes it’s easy to see the next piece of metal. Sometimes, it’s not. The most difficult part is to control your fear. It’s normal for humans to be afraid of falling, so it’s difficult not to feel fear. But when you move away from the wall, the harness and the ropes hold you，and you begin to feel safe. You move slowly until you reach the top.
Climbing attracts people because it’s good exercise for almost everyone. You use your whole body, especially your arms and legs. This sport gives your body a complete workout. When you climb，both your mind and your body can become stronger. What can we infer from the passage?
| A．People are fairly interested in climbing nowadays. |
| B．It is impossible to build up（强健） one’s body by climbing. |
| C．People can only learn the skill of climbing outdoors. |
| D．It is always easy to see holding places in climbing. |
. The most difficult thing to do in wall climbing is________.
| A．to tie ropes to your harness | B．to control your fear |
| C．to move away from the wall | D．to climb straight up |
. The word “workout” underlined（被划线） in the last paragraph most probably means________.
| A．settlement | B．exercise | C．excitement | D．tiredness |
Why does the author write this passage?
| A．To tell people where to find gyms. |
| B．To prove the basic need for climbing. |
| C．To encourage people to climb mountains. |
| D．To introduce the sport of wall climbing. |
