A fad diet is a diet that suddenly becomes popular, usually because it promises people that they will lose a lot of weight overnight. Although dieters may really show weight loss from a fad diet, they will almost certainly get back the weight if their usual eating habits (习惯) remain unchanged. Moreover, fad diets continuously call for special products of questionable value or for “health foods” that may cost twice as much as supermarket(超市) foods. Worse yet, certain fad diets don't include nutrients(营养)good for health. People have been known to become very ill as a result of following medically unhealthy diets.
The worse fact of fad diets, though, is that they keep people who are over-weight or sick from receiving the medical care that they truly need.The word “fad” in the first sentence means ______.

Dr. Jack M. Gwaltney, Jr. a professor at the University Of Virginia School Of Medicine infected six student volunteers with virus, the most common cause of colds. A few days later, when they were coughing and sneezing, he gathered 37 more people and divided them into three groups. Group 1 members spent three days and nights in the same room with one of the infected students, separated by a screen so they couldn't touch one another. Group 2 sat around a table while an infected volunteer talked, coughed and sang to them. Group 3 held hands with an infected student for ten seconds, and then touched their own noses or eyes.
Although most scientists at the time, the mid-70s, believed colds were spread by virus-laden droplets spread through the air when infected people coughed or sneezed, Gwaltney suspected physical contact might play an important role. Sure enough, of the 15 people who had touched a student volunteer, 11 became infected—compared with only one of those who had been sitting at the table, and none who had spent three days and nights together.
"The best evidence we have is that hand-to-hand contact is the most efficient way of transmitting virus," says Gwaltney. The study was one of a series that helped establish Gwaltney's reputation as a leading authority. Dr. Robert Couch says, "It would not be inappropriate to call him Mr. Common Cold."
When Gwaltney is asked how close scientists are to finding a cure, he replies: "If you mean ‘get rid of’, I don't think we're going to be able to do that with cold viruses any time soon. But if you look in the dictionary, you'll see that 'cure' is explained as a successful treatment. And we're not just getting more effective at treating the symptoms (症状)—we're getting at the root cause too. "Dr. Jack M. Gwaltney conducted the experiment in order to__________.
| A．find out the most common cause of colds |
| B．infect the student volunteer |
| C．find out the role physical contact plays in the common colds |
| D．find out the role virus-laden air plays in the infection of colds |
The result of the experiment shows that ___ plays an important role in the infection of colds.
| A．sneezing at the infected person |
| B．touching the infected person |
| C．sitting together with the infected person |
| D．talking with the infected person |
Which of the following statements is TRUE according to the passage?
| A．Dr. Gwaltney was sure that hand-to-hand touch is the cause of the common cold. |
| B．Only one of the people who had spent three days and nights together became infected. |

| D．Dr. Gwaltney tested altogether 43 volunteers to see how they could develop colds. |
Mr. Common Cold is______.
| A．a newly-found virus |
| B．a nickname (绰号) of respect to Dr. Gwaltney |
| C．a method to cure colds |
| D．a way by which the other scientists laughed at Dr. Gwaltney |

| D．they have made much progress in dealing with colds |
By the mid-nineteenth century, the term "icebox" had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in hotels, taverns(酒馆), and hospitals, and by some forward-looking city dealers in fresh meat, fresh fish, and butter. After the Civil War (1861-1865), as ice was used to refrigerate freight cars, it also came into household use. Even before 1880, half of the ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston and Chicago, went to families for their own use. This had become possible because a new household convenience, the icebox, a precursor (前身) of the modern fridge, had been invented.
Making an efficient icebox as not as easy as we might now suppose. In the early nineteenth century, the knowledge of the physics of heat, which was essential to a science of refrigeration, was rudimentary(未发展的). The commonsense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping up the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the delicate balance of insulation(绝缘) and circulation needed for an efficient icebox.
But as early as 1803, and ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, for which the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium price(高价) for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool.Where was ice used after the Civil War?
| A．In refrigerating freight cars and households. |
| B．In hotels, taverns and hospitals |
| C．In families of New York, Philadelphia, and Baltimore. |
| D．In fresh meat, fish and butter by city dealers. |
What was essential to to make an icebox efficient according to the passage?
| A．Keeping the ice from melting |
| B．Knowledge of the physics of heat. |
| C．Balance of insulation and circulation |
| D．Making efforts to reduce the use of ice |
The second paragraph is mainly about_____
| A．the deveopment of icebox |
| B．the theoretical foundation of icebox |
| C．the wrong ideas about icebox |
| D．the way of using icebox |
What can we infer from the text?
| A．Thomas Moore is the inventor of modern fridge |
| B．The butter produced by Thomas Moored is better in quality than other famers’ |
| C．Knowledge of the physics of heat plays an important part in inventing a good icebox |
| D．Before 1880, most of the sold ice was used for family use. |
Without an ice box, farmers had to go to the market at night ________.
| A．to sell their produce at high price |
| B．to go home earlier |
| C．to keep their produce fresh |
| D．to win more customers than their competitors |
We once had a poster competition in our fifth grade art class.
“You could win prizes,” our teacher told us as she wrote the poster information on the blackboard. She passed out sheets of construction paper while continuing, “The first prize is ten dollars. You just have to make sure that the words on the blackboard appear somewhere on your poster.”
We studied the board critically. Some of us looked with one eye and held up certain colors against the blackboard, rocking the sheets to the right or left while we conjured up our designs. Others twisted their hair around their fingers or chewed their erasers while deep in thought. We had plans for that ten-dollar grand prize, each and every one of us. I’m going to spend mine on candies, one hopeful would announce, while another practiced looking serious, wise and rich.
Everyone in the class made a poster. Some of us used parts of those fancy paper napkins, while others used nothing but colored construction paper. Some of us used big designs, and some of us preferred to gather our art tidily down in one corner of our poster and let the space draw the viewer’s attention to it. Some of us would wander past the good students’ desks and then return to our own projects with a growing sense of hopelessness. It was yet another grown-up trick of the sort they seemed especially fond of, making all of us believe we had a fair chance, and then always—always—rewarding the same old winners.
I believe I drew a sailboat, but I can’t say that with any certainty. I made it. I admired it. I determined it to be the very best of all of the posters I had seen，and then I turned it in.
Minutes passed.
No one came along to give me the grand prize, and then someone distracted me, and I probably never would have thought about that poster again.

| A．It must appear in time. |
| B．It must be done in class. |

I was walking along the deserted main street of a small seaside town in the north of England looking somewhere to make a phone call. My car had broken down outside the town and I wanted to get in touch with the Automobile Association .Low gray clouds were drifting across the sky and there was a cold damp wind blowing off the sea. It had rained in the night and water was dripping from the bare trees that lined the street. I was glad that I was wearing a thick coat.
I could see no call box, nor was there anyone at that early hour I could ask. I had thought I might find a shop selling the Sunday papers or a milkman doing his job, but the town was completely dead.
Then suddenly I found what I was looking for. There was a small post office, and almost hidden from sight in a dark narrow street next to it was the town's only public call box, which badly needed a coat of paint, I hurried forward but stopped in astonishment when I saw through the dirty glass that there was a man inside. He was very fat, and was wearing a cheap blue plastic raincoat and rubber boots. I could not see his face - he was bending forward over the phone with his back pressed against the glass and didn't even raise his head at the sound of my coming nearer and nearer. Carefully and surprisedly, I remained standing a few feet away and lit a cigarette to wait my turn. It was when I threw the dead match on the ground that I noticed something bright red trickling from under the call box door.The author was walking through the small seaside town__________.

Chinese female film stars, like Gong Li and Zhang Ziyi, due to the charm of their films, have set a good image for Chinese women in the world. Compared with Chinese women, the image of Chinese men is not so good in the eyes of Western women, the Shanghai Evening Post reported.
In March 2006, Zhang Jiehai, a doctorate（博士学位） holder at the Sociology Institute of the Shanghai Academy of Social Sciences, led a research team to investigate how Western women look at Chinese men. The survey shows that many Western women think Chinese men are mostly known for their care for the family. Chinese men, as the Western women say, are willing to spend money for women. As to their shortcomings, Western women think that Chinese men do not have good manners and that some Chinese men have the habit of spitting everywhere, keeping nails and hair long, picking their noses and ears in public places, and not cleaning their teeth thoroughly. These bad habits make many Western women think that Chinese men are unwilling to take care of their personal image.
The survey was carried out in two ways, by questionnaires and interviews. All the respondents（调查对象） agreed that Chinese men show much tender loving care for the family and that many Chinese men do know how to respect women. They open the door for women and carry their handbags for them. For some American women, the bad image of Chinese men in the world is largely because of Hollywood films. In many Hollywood films, Chinese men usually do not have a good image. But this has been changed by Hong Kong film star Chow Yun-Fat. After the Chinese film Crouching Tiger, Hidden Dragon was shown in cinemas in the United States in 2002, many Westerners began to change their impression of Chinese men.Which statement best expresses the main idea of the first paragraph?
| A．Chinese female film stars enjoy as great fame as Chinese male film stars in the world. |
| B．Chinese male film stars do not perform well in their films in the eyes of Western women. |
| C．Chinese female film stars don’t like Western male film stars. |
| D．Chinese female film stars have set a good image for Chinese women. |
Which is NOT mentioned as the shortcoming of Chinese men in Paragraph 2?
| A．Spitting everywhere. |
| B．Speaking too loudly in public places. |
| C．Not cleaning their teeth thoroughly. |
| D．Picking their noses and ears in public places. |
In some American women’s eyes, Chinese men’s images are bad because of ______.
| A．Chinese female film stars |
| B．Chinese male film stars |
| C．Hollywood films |
| D．Film stars in Hong Kong |
What does the passage mainly deal with?
| A．Chinese men in the eyes of Western women. |
| B．Foreign film stars and Chinese film stars. |
| C．Chinese women in the eyes of Western men. |
| D．Chinese film stars in Hollywood films. |
