In the United States, 30 percent of the people have a “weight problem”。To many people the cause is obvious (明显的): they eat too much. But scientific evidence (证据) does little to support this idea. Going back to America of 1910, we find that people were thinner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn’t watch television.
Several modern studies, moreover, have shown that fatter people don’t eat more on average than thinner people. A 1979 study of 3,545 London office workers showed that fat people eat less than slim (苗条的) people.
Studies also show that slim people are more active than fat people. A study by a research group at Stanford University found the following interesting facts:
The more the man ran, the greater loss of the body fat
The more they ran, the greater increase in food intake.
Thus, those who ran the most ate the most, yet lost the greatest amount of body fat. Nowadays many Americans have the problem that ______.
| A．they are too slim | B．they work too hard | C．they are too fat | D．they lose too much body fat |

There are many colors in nature. But do you know if a color has weight? I think you’ll say “no”. But I am afraid you are wrong. If you don’t believe, you may do a small experiment.
First, put two objects（物体） with the same weight into two boxes. Then cover the box. Third, wrap(裹) one box with a red piece of paper, the other with a white piece of paper. OK. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier.
Why do you think so? A scientist found that different colors have different weights in a man’s mind. So he did many tests and at last he got the result. That is to say, every color has its own weight in our mind and their order is the same. The heaviest color is red, then blue, green, yellow and white.
The scientist told us that colors also have smell. Can you smell the color? Of course not. Then why did the scientist say so? That is because every color stands for (代表)a kind of light with a certain wavelength(波长). It reaches our brain through sense organs(感觉器官).
According to this discovery, scientists say that people accept the colors they like, and refuse the colors they hate. So your body and mind will be healthy by using the colors you like. Or you’ll be nervous or ill. For example, if you stay in a room with red windows, wallpapers and furniture for two hours, you’ll feel you have been there for four hours. But if the room is blue, you’ll feel you have been there for only an hour. Another example, if a person walks out of a red room and into a blue room, his temperature will fall. That means our body temperature will change with different colors.The idea of the second paragraph is to tell us ________.
| A．a red box is heavier than a white one |
| B．a color has weight in one’s mind |
| C．white paper is lighter than red paper |
| D．you can know the weight of a color by holding it |
Why did the scientist say colors have smell?
| A．Because people can sense(感觉) the light from colors. |
| B．Because we can smell colors with our noses. |
| C．Because every color has its own sweet smell. |
| D．Because every color can give off light of the same length. |
If a person walks from a blue room to a red room, his body temperature will__________.
| A．rise | B．fall | C．stay the same | D．change now and then |
It can be known from the text that________.
| A．colors have order in weight |
| B．colors can change the weight of an object |
| C．people would stay longer in a room with red windows |
| D．colors can affect （影响）our mood （情绪）and health |

Sitting on a chair all day in school can make anyone want to move around. So, more and more teachers are letting students have a ball. By sitting on exercise balls instead of chairs , teachers find students’ posture(姿势) and attention improve.
Dottie Pownall, a fifth-grade teacher in West Virginia, USA, has been using balls as chairs since December 2008. “The students love them”, she says. Pownall took a survey(调查) of her students. She found that 80% of the students thought sitting on the balls helped them pay more attention to what they were learning.
The teacher, Pisa Witt, felt so strongly about the use of balls as chairs, she started Witt Fitt. This company encourages the use of the balls. And the company educates not only teachers but also students on how to use them. “Our products are used in 24 states, three provinces in Canada, Puerto Rico (波多黎各) and Japan,” says Witt, “ Research shows that sitting on the balls makes them sit up straighter（直的）. You can slouch(低头垂肩地坐)on a ball,” says Witt, “but it feels bad.” Because the students are moving, their blood (血液) increases. That carries more oxygen( 氧气) to the brain , so the kids have more energy and can pay attention longer.
“Besides, they’re fun.” says Pownall.What will happen if a student sits on a chair all day in school? The student will_________.
| A．pay more attention to his lessons | B．be fun |
| C．like to move around | D．sit up straighter |
How long has Dottie Pownall used the balls?
| A．About four years. | B．Only one year. |
| C．In 2008. | D．Since he was a fifth-grade teacher. |
In how many countries are the balls used as the students’ chairs?
| A．Four. | B．Three. | C．Two. | D．One. |
Teachers choose balls instead of chairs because sitting on balls helps the kids _________.
| A．improve the students’ posture and attention |
| B．slouch on the chairs |
| C．have fun |
| D．Both A and C are correct answers |
Which is better for kids to study in class, sitting on a chair or sitting on a ball?
| A．Sitting on a chair. | B．Sitting on a ball. |
| C．They are the same. | D．We don’t know. |
Human wants seem endless, When a starving man gets a meal, he begins to think about an overcoat; when a manager gets a new sports car, he dreams of country clubs and pleasure boats dance into view.
The many wants of mankind might be regarded as making up several levels. When there is money enough to satisfy one level of wants, another level appears.
The first and most basic level of wants is food. Once this want is satisfied, a second level of wants appears: clothing and some sort of shelter. By the end of World War II these wants were satisfied for a great majority of Americans. Then a third level appeared. It included such items as cars and new houses.
By 1957 or 1958 this third level of wants was fairly well satisfied. Then in the late 1950s a fourth level of wants appeared: the “life-enriching” level. While the other levels mean physical satisfaction—the feeding, comfort, safety and transportation of the human body—this level means mental needs for recognition, achievement and happiness, It includes a variety of goods and services many of which could be called “luxury” items. Among them are vacation trips, the best medical care and entertainment. Also included here are fancy foods and the latest styles in clothing.
On the fourth level, a greater percentage of consumers spending goes to services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of wants as their income increases, or will they continue to demand luxuries and personal services on the fourth level?
A fifth level probably would be wants that can be achieved by community action. Consumers may be spending more on taxes and crime. After filling our stomachs, our garages, and our minds, we now may seek to ensure the health and safety to enjoy more fully the good things on the first three levels.According to the passage, man will begin to think about such needs as housing and clothing only when _______
| A．he has saved up enough money |
| B．he has grown dissatisfied with his simple shelter |
| C．he has satisfied his hunger |
| D．he has learned to build houses |
It can be inferred from the passage that by the end of World War II most Americans ______
| A．were very rich |
| B．were very poor |
| C．Had the good things on the first three levels |
| D．didn’t own cars |
Which of the following is NOT related to “physical satisfaction”?
| A．A successful career | B．A comfortable house |
| C．A good service | D．A family car |
Which is the main want of man on the fourth level?
| A．The more goods, the better |
| B．The more mental satisfaction, the better |
| C．The more “luxury” items, the better |
| D．The more earning, the better |
The author thinks that a fifth level______
| A．would be a little better than the fourth level |
| B．may be a lot more desirable than the first four |
| C．can be the last and most satisfying level |
| D．will come true if the government takes actions |
With only a click of the mouse, rumours（谣言）can be forwarded between microblogs（微博）very quickly. As an example, recently, sensitive netizens discovered that some photos displayed on microblogs describing Beijing’s June rainstorm had actually been fabricated.
Sina.com is one of the major Internet portals in China with hundreds and thousands of users, and a majority of celebrities and famous citizens have their microblog accounts on this portal. As recently as six months ago, the website decided to establish a specialized team to prove rumours and provide accurate information for its users. Tan Chao is in charge of the team.
“ Before I took the job, I usually couldn’t identify what information was real and what was fake. But during the process of identification, we discovered that a lot of information was false, including fake photos, fake news stories and rumours that had been spread through microblogs.”
It’s not just website portals which are taking on fact-checking responsibilities, but also a number of civic-minded netizens, who recently set up a Rumour Identification Federation on Sina.com’s microblog system to help netizens identify fake information online.
Dian Zizheng is the team leader of the federation. He says they’ve publicized more than 150 pieces which contradict rumours, which attracted more than 10 thousand visitors within two months.
“We live in an age of new media, so we can’t use the old methods to prove rumours. We can’t wait for the media to prove the facts with related administrative（行政） departments and then release a formal announcement. We can’t allow rumours to run wild and then deal with it, we need to fight rumours while they’re spreading. I think that this is the best way to deal with rumours nowadays.”
Some experts say this displays the advantages of the internet compared to other traditional media. The open platform allows information to be examined and clarified by netizens. But experts like Ding Wengguo,President of the Journalism and Communication College at the China University of Political Science and Law says this self-correction function of the Internet is still quite limited.
“It’s still quite different to tell which information is true in such an open environment by just reading a number of different opinions on the same issue. This is something which we need to pay attention to. If society is flooded with too much false information, and it’s allowed to spread in such a fast manner, then people will be suspicious（怀疑的） of all kinds of information including important information from authorities. It also worsens problems relating to social communications and mutual-understanding, which in turn harms society as a whole.”
Experts suggest that the government should react more quickly in the Internet age. Once a rumour begins to spread, administrative departments should make announcements as early as possible to drive away rumours before they lead to bad outcomes.Sina.com decided to found a specialized team to __________.
| A．prevent the spread of rumours on the Internet |
| B．advance the development of microblog |
| C．limit the number of microblog |

Which of the following is true according to the text?
| A．All the rumours have been spread through microblog. |
| B．Sina.com is the most popular internet portal in China. |
| C．Traditional media don’t prove rumours to spread. |
| D．The photos displayed on microblogs might have side effects. |
The underlined word “fabricated” in the first paragraph can be replaced by _________.
| A．made up | B．dug out | C．got round | D．given away |
What is the best way to prove rumors on microblogs?
| A．Shutting down the website immediately. |
| B．Substituting the Internet for traditional media. |
| C．Examining and checking while they are spreading . |
| D．Making announcements after they are spread. |
The writer cited Ding Wenguo’s words in Paragraph 8 to________.
| A．draw a conclusion | B．introduce a topic |
| C．support an argument | D．describe a scene |
What’s the writer’s attitude towards the rumours from microblogs according to the passage?
