The common cold is the world's most widespread illness, which is plagues (瘟疫) that flesh receives. The most widespread fallacy (谬误) of all is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one.
If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.
During the First World War soldiers who spent long periods in the trenches (战壕) cold and wet, showed no increased tendency to catch colds. In the Second World War prisoners at the notorious Auschwitz concentration camp (奥斯维辛集中营), naked and starving, were astonished to find that they seldom had colds.
At the Common Cold Research Unit in England, volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be dipped with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.
No one has yet found a cure for the cold. There are drugs and pain-killer pills such as aspirin, but all they do is relieve the symptoms.How many examples are offered by the writer to support his argument?
A.4 | B.5 | C.6 | D.3 |

It was a village in India. The people were poor . However, they were not unhappy. After all , their forefathers had lived in the same way for centuries.
Then one day, some visitors from the city arrived . They told the villagers there were some people elsewhere who liked to eat frog’s legs. However, they did not have enough frogs of their own, and so they wanted to buy frogs from other places.
This seemed like money for nothing . There were millions of frogs in the fields around, and they were no use to the villagers. All they had to do was catch them . Agreement was reached, and the children were sent into the fields to catch frogs. Every week a truck arrived to collect the catch and hand over the money. For the first time ,the people were able to dream of a better future. But the dream didn’t last long.
The change was hardly noticed at first ,but it seemed as if the crops were not doing so well. More worrying was that the children fell ill more often ,and ,there seemed to be more insects around lately.
The villagers decided that they couldn’t just wait to see the crops failing and the children getting weak. They would have to use the money earned to buy pesticides (杀虫剂)and medicines. Soon there was no money left .
Then the people realized what was happening. It was the frog .They hadn’t been useless. They had been doing an important job-eating insects. Now with so many frogs killed , the insects were increasing more rapidly. They were damaging the crops and spreading diseases.
Now, the people are still poor .But in the evenings they sit in the village square and listen to sounds of insects and frogs. These sounds of the night now have a much deeper meaning. From Paragraph 1 we learn that the villagers .

Too much TV-watching can harm children’s ability to learn and even reduce their chances of getting a college degree, new studies suggest in the latest effort to examine the effects of television on children.
One of the studies looked at nearly 400 northern California third-graders. Those with TVs in their bedrooms scored about eight points lower on math and language arts tests than children without bedrooms TVs.
A second study, looking at nearly 1,000 grown-ups in New Zealand, found lower education levels among 26-year-olds who had watched lots of TV during childhood. But the results don’t prove that TV is the cause and don’t rule out that already poorly motivated youngsters(年轻人)may watch lots of TV.
Their study measured the TV habits of 26-year-olds between ages 5 and 15. Those with college degrees had watched an average of less than two hours of TV per weeknight during childhood, compared with an average of more than 2½ hours for those who had no education beyond high school.
In the California study, children with TVs in their rooms but no computer at home scored the lowest, while those with no bedroom TV but who had home computers scored the highest.
While this study does not prove that bedroom TV sets caused the lower scores, it adds to accumulating findings that children shouldn’t have TVs in their bedrooms.According to the California study, the low-scoring group might____________.
A.have watched a lot of TV |
B.not be interested in math |
C.be unable to go to college |
D.have had computers in their bedrooms |
What is the researchers’ understanding of the New Zealand study results?
A.Poorly motivated 26-year-olds watch more TV. |
B.Habits of TV watching reduce learning interest. |
C.TV watching leads to lower education levels of the 15-year-olds. |
D.The connection between TV and education levels is difficult to explain. |
What can we learn from the last two paragraphs?
A.More time should be spent on computers. |
B.Children should be forbidden from watching TV. |
C.TV sets shouldn’t be allowed in children’s bedrooms. |
D.Further studies on high-achieving students should be done. |
What would be the best title for this text?
A.Computers or Television |
B.Effects of Television on Children |
C.Studies on TV and College Education |
D.Television and Children’s Learning Habits |
If you ask people to name the one person who had the greatest effect on the English language, you will get answers like “Shakespeare,” “Samuel Johnson,” and “Webster,” but none of these men had any effect at all compared to a man who didn’t even speak English-William the Conqueror.
Before 1066, in the land we now call Great Britain lived peoples belonging to two major language groups. In the west central region lived the Welsh, who spoke a Celtic language, and in the north lived the Scots, whose language, though not the same as Welsh, was also Celtic. In the rest of the country lived the Saxons, actually a mixture of Anglos, Saxons, and other Germanic and Nordic peoples, who spoke what we now call Anglo-Saxon (or Old English), a Germanic language. If this state of affairs had lasted, English today would be close to German.
But this state of affairs did not last. In l066 the Normans led by William defeated the Saxons and began their rule over England. For about a century, French became the official language of Eng-land while Old English became the language of peasants. As a result, English words of Politics and the law come from French rather than German. In some cases, modern English even shows a distinction (区别) between upper-class French and lower-class Anglo-Saxon in its words. We even have different words for some foods, meat in particular, depending on whether it is still out in the fields or at home ready to be cooked, which shows the fact that the Saxon peasants were doing the farming, while the upper-class Normans were doing most of the eating.
When Americans visit Europe for the first time, they usually find Germany more "foreign" than France because the German they see on signs and advertisements seems much more different from English than French does. Few realize that the English language is actually Germanic in its beginning and that the French influences are all the result of one man's ambition. The two major languages spoken in what is now called Great Britain before l066 were
A.Welsh and Scottish | B.Nordic and Germanic |
C.Celtic and Old English. | D.Anglo-Saxon and Germanic |
Which of the following groups of words are, by inference, rooted in French?
A.president, Lawyer, beef | B.president, bread, water |
C.bread, field, sheep | D.folk, field, cow |
Why does France appear less foreign than Germany to Americans on their first visit to Europe?
A.Most advertisements in France appear in English. |
B.They know little of the history of the English language. |
C.Many French words are similar to English ones. |
D.They know French better than German. |
What is the subject discussed in the text?
A.The history of Great Britain. |
B.The similarity between English and French. |
C.The rule of England by William the Conqueror. |
D.The French influences on the English language. |

In the days when an ice cream sundae cost much less, a 10-year-old boy entered a hotel coffee shop and sat at a table. A waitress put a glass of water in front of him. “How much is an ice cream sundae?”“Fifty cents,” replied the waitress. The little boy pulled his hand out of his pocket and studied a number of coins in it. “How much is a dish of plain ice cream?” he required. Some people were now waiting for a table and the waitress was a bit impatient. “Thirty-five cents,” she said rudely. The little boy again counted the coins. “I’ll have the plain ice cream,” he said.
