Why do people shrink？
Did you ever see the movie Honey，I shrunk the kids？ It’s about a wacky dad（who’s also a scientist）wh0 accidentally shrinks his kids with his homemade miniaturizing invention．0ops! __（1）．
For older people，shrinking isn’t that dramatic or sudden at all． It takes place over years and may add up to only one inch or so off of their adult height（maybe a 1ittle more，maybe less）， and this kind of shrinking can’t be magically reversed，although there are things that can be done to stop it or slow it down．_（2）．
There are a flew reasons．As people get older，they generally lose some muscle and flat from their bodies as part of the natural aging process．Gravity （the force that keeps your feet on the ground） take hold，and the bones in the spine，called vertebrae，may break down or degenerate，and start to collapse into one another_ （3）．But perhaps the most common reason why some older people shrink is because
of osteoporosis．
0steoporosis occurs when too much spongy bone tissue（which is found inside of most bones）is broken down and not enough new bone material is made．（4）． Bones become smaller and weaker and can easily break if someone with osteoporosis is injured． Older people—especially women，who generally have smaller and lighter bones to begin with--are more likely to develop osteoporosis．As years go by，a person with osteoporosis shrinks a little bit．
Did you know that every day you do a shrinking act？ You aren’t as tall at the end of the day as you are at the beginning．That’s because as the day goes on，water in the disks of the spine gets compressed（squeezed）due to gravity，making you just a tiny bit shorter．Don’t worry，though．_（5）
A．They end up pressing closer together，which makes a person lose a little height and become shorter．
B．0rice you get a good night’s rest，your body recovers，and the next morning，you’re standing tall again． C．0ver time．bone is said to be lost because it’s not being replaced．
D．Luckily，there are things that people cab do to prevent shrinking．
E．The kids spend the rest of the movie as tiny people who are barely Visible while trying to get back to their normal size．
F．But why does shrinking happen at all ？

第4题

Perhaps the most famous theory, the study of body movement, was suggested by Professor Ray Birdwhistell. He believes that physical appearance is often culturally(文化的)programmed. In other words, we learn our looks ---- we are not born with them. A baby has generally unformed face features(特征). A baby, according to Bird whistle, learns where to set the eyebrows(眉毛)by looking at those around ---- family and friends. This helps explain why the people of some areas of the United States look so much alike, New Englanders or Southerners have certain common face features that cannot be explained by genetics(遗传学). The exact shape of the mouth is not set at birth, it is learned after. In fact, the final mouth shape is not formed until well after new teeth are set. For many, this can be well into grown-ups. A husband and wife together for a long time often come to look somewhat alike. We learn our looks from those around us. This is perhaps why in a single country there are areas where people smile more than those in other areas. In the United States, for example, the South is the part of the country where the people smile most frequently. In New England they smile less, and in the western part of New York State still less. Many Southerners find cities such as New York cold and unfriendly, partly because people on Madison Avenue smile less than people on Peachtree Street in Atlanta, Georgi A. People in largely populated areas also smile and greet each other in public less than do people in small towns.
(1). People who live () are more friendly.
A、in largely populated areas
B、in New York city
C、in the country
D、in the North
(2). This passage might have been taken out of a book dealing with().
A、physics
B、chemistry
C、biology
D、none of the above

第5题

When Mrs. Joseph Groger died recently in Vienna, Austria, people asked, "Why did she live to be 107？" Answers were provided by an investigation made among 148 Viennese 一 men and women who had reached the age of 100. Somewhat surprising was the fact that the majority had lived most their lives in cities. In spite of the city's image as an unhealthy place, city living often provides benefits that country living may lack. One factor seems to be important to these long-lived persons.
This factor is exercise. In the cities, it is often faster and less frustrating 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 tenants must climb stairs. City dwellers(居民) can usually walk to local supermarkets. Since parking spaces are hard to find, there is often no alternative to walking.
On the other hand, those who live in the country and suburbs do not have to walk every day. In fact the opposite is often true. To go to school, work or almost anywhere else, they must ride in cars.
1)、The Vienna survey may help to explain the long life of people like Mrs. Groger.
A.T
B.F
2)、The purpose of the second paragraph is to list some comments made by city dwellers.
A.T

3)、To reach the third floor of a building, it would probably be most healthy to walk up the stairs.
A.T

4)、Suburban people probably drive rather than walk because they don't need exercises.

5)、We can conclude from the passage that walking is a healthy exercise.

第6题

A very important world problem is the increasing number of people who actually inhabit this planet. The limited amount of land and land resources will soon be unable to support the huge population if it continues to grow at its present rate.
So why is this huge increase in population taking place？ It is really due to the spread of the knowledge and practice of what is becoming known as "Death Control". You have no doubt heard of the term "Birth Control". "Death Control" is something rather different. It recognizes the work of the doctors and scientists who now keep alive people who, not very long ago, would have died of a variety of then incurable diseases. Through a wide variety of technological innovations that include farming methods and the control of deadly diseases, we have found ways to reduce the rate at which we die. However, this success is the very cause of the greatest threat to mankind.
If we examine the amount of land available for this ever-increasing population, we begin to see the problem. If everyone on the planet had an equal share of land, we would each have about 50,000 square meters. This figure seems to be quite encouraging until we examine the amount of usable land we actually have. More than three-fifths of the world's land cannot produce food.
Obviously, with so little land to support us, we should be taking great care not to reduce it further. But we are not! Instead, we are consuming its "capital" — its nonrenewable fossil fuels and other mineral deposits that took millions of years to form. but which are now being destroyed in decades. We are also doing the same with other vital resources not usually thought of as being nonrenewable such as fertile soils, groundwater and the millions of other species that share the earth with us.
It is a very common belief that the problems of the population explosion are caused mainly by poor people living in poor countries who do not know enough to limit their reproduction. This is not true. The actual number of people in an area is not as important as the effect they have on nature. Developing countries do have an effect on their environment, but it is the populations of richer countries that have a far greater impact on the earth as a whole.
According to the article, what contributes to the population increase？
A．Birth explosion.
B．Birth Control.
C．Technological innovations.
D．Death Control.

A typical lion tamer （驯兽师) in people’s mind is an entertainer holding a whip （鞭子
A typical lion tamer (驯兽师) in people’s mind is an entertainer holding a whip (鞭子)and a chair. The whip get all of the attention, but it’s mostly for show. In reality, it’s the chair that does the important work. When a lion tamer holds a chair in front of the lion’s face, the lion tries to focus on all four legs of the chair at the same time. With its focus divided, the lion becomes confused and is unsure about what to do next. When faced with so many options, the lion chooses to freeze and wait instead of attacking the man holding the chair.How often do you find yourself in the same position as the lion？ How often do you have something you want to achiever (e,g. lose weight, start a business, travel more )–only to end up confused by all of the options in front of you and never make progress？ This upsets me to no end because while all the experts are busy debating about which option is best, the people who want to improve their lives are left confused by all of the conflicting information. The end result is that we feel like we can’t focus or that we’re focused on the wrong things, and so we take less action, make less progress, and stay the same when we could be improving. It doesn’t have to be that way. Anytime you find the world waving a chair in your face, remember this: All you need to do is focus on one thing. You just need to get started. Starting before you feel ready is one of the habits of successful people. If you have somewhere you want to go, something you want to accomplish, someone you want to become--take immediate action. If you’re clear about where you want to go, the rest of the world will either help you get there or get out the way.
(1)、Why does the lion tamer use a chair？ ()
A、To trick the lion.
B、To show off his skill .
C、To get ready for a fight.
D、To entertain the audience.
(2)、In what sense are people similar to a lion facing a chair？ ()
A、They feel puzzled over choices.
B、They hold on to the wrong things.
C、They find it hard to make changes.
D、They have to do something for show.
(3)、What is the author’s attitude towards the experts mentioned in paragraph 3？ ()
A、Tolerant
B、Doubtful
C、Respectful
D、Supportive
(4)、When the world is “waving a chair in your face”, you’re advised to_____. ()
A、wait for a better chance
B、break your old habits
C、make a quick decision
D、ask for clear guidance
(5)、In the fifth paragraph, the word “accomplish” means ______. ()
A、achieve.
B、abuse.
C、comfort.
D、delete.

Everyone knows that the favourite food of the Americans is the hamburgers.

Then when the food is ready, they take it to their tables themselves.They can eat it in the restaurant or take the food out in a plastic(塑料的) box and eat it at home, at work, or in a park. At some restaurants people can drive up beside a window. They ask for the food and a worker hands it to them through the window. Then they drive off and eat in their cars. Some fast-food restaurants also sell fish, chicken, sandwiches, soft drinks and so on. Fast-food restaurants are very popular because the service(服务) is fast and the food is not too dear.

阅读下面的文章，根据文章内容，完成相应的选择题。（每题 10 分）
Door-Knocking
Door-knocking is the most effective way of making face-to-face community contact, but it has become a lost art. With the recent focus on customer privacy, door-knocking seems like an intrusion into other people' s lives. But those who try it for the first time are usually surprised by the pleasant reception they receive. Here are some suggestions that will help you promote your services face-toface.
BEFORE YOU GO OUT
◆ Begin with a door hanger
Try leaving a door hanger two days before you go door-knocking. It should briefly describe the project and say that someone will be around in person.
◆ Wear an official name tag
Door-knockers should wear name tags with the logo of their organization. The best name tags will also include a color photo and the name of the caller.
◆ Have people knock their own blocks
The easiest way to do door-knocking is to try your local area first. Being a neighbor creates an immediate connection with the person answering the door; after that, everything else is easy.
◆ Find a good excuse to door-knock
A short survey about local concerns or a current project is a good excuse. Figure out responses for various situations. What if the person who answers the door cannot speak English? What if a child answers the door?
WHEN YOU GO OUT
◆ When to go and what to do first
The best times to knock are usually Saturdays. On other days, after dinner is ideal. When someone answers the door, smile and introduce yourself; say you are a volunteer and, if it helps, state where you live. Give the name of your organization and, briefly, the reason for the visit.
◆ State what action the other person should take and the benefits
Tell the person what they need to do and how their actions will benefit themselves and others. If a person hesitates, emphasize benefits you' ve already mentioned and then, if necessary, add further benefits. If a person agrees, follow up immediately. If possible, get a donation,a signature, or a promise.
◆ Record contact information on the spot
Record names, addresses, e-mail addresses, phone numbers, and responses to questions on the spot. You won' t remember them later!
（1）Why does the author say that door-knocking has become a lost art?
A. It is not effective, no one will take this method any more.
B. People focus on privacy increasingly, so door-knocking seems like an intrusion into other people' s lives
C. It is very difficult to do door-knocking， no one knows how to do it now.
（2） Which step should be firstly taken when you try door-knocking?
A. Find a good excuse to door-knock
B. Wear an official name tag
C. Leave a door hanger
（3） What does the underlined phrase “on the spot” mean?
A. without delay
B. at some place
C. in a difficult situation
（4） Which time is not appropriate for door knocking?
A. Saturday afternoon
B. Monday morning.
C. Thursday evening.
（5） Who will receive pleasant reception when they try door-knocking?
A. A stranger who is not living in this community and gives no notice for his/her visit.
B. An offensive acquaintance who comes at any time.
C. A neighbor who does good preparation and has significant project to introduce.
