Passage Two

Questions 26 to 30 are based on the following passage.

Scientists have established that influenza viruses taken from man can cause the disease in animals. In addition，man can catch the disease from animals. In fact，a great number of wild birds seem to carry the virus without showing any evidence of illness. Some scientists conclude that a large family of influenza viruses may have evolved in the bird kingdom，a group that has been on the earth 100 million years and is able to carry the virus without contracting the disease. These are even convincing evidence to show that virus strains are transmitted from place to place and from continent to continent by migrating birds.

It is known that two influenza viruses can recombine when both are present in an animal at the same time. The result of such recombinations is a great variety of strains constraining different H and N spikes. This raises the possibility that a human influenza virus can recombine with an influenza virus form. a lower animal to produce an entirely new spike.

Research is underway to determine if that is the way that major new strains come into being. Another possibility is that two animal influenza strains may recombine in a pig，for example，to produce a new strain which is transmitted to man.

According to the passage，scientists have discovered that influenza viruses______.

A. cause ill health in wild birds

B. do not always cause symptoms in birds

C. are rarely present in wild birds

D. change when transferred from animals to man

One silly question I simply can't stand is "How do you feel". Usually the question is asked of a man in action--a man on the go, walking along the street, or busily working at his desk. So what do you expect him to say? He'll probably say, "Fine, I'm all right." But "you've put a bug in his ear" — maybe now he's not sure. If you are a good friend, you may have seen something in his face, or his walk, that he did not realize that morning. It starts him worrying a little. First thing you know, he looks in a mirror to sec if everything is all right, while you go merrily on your way asking someone else, "How do you feel?"

Every question has its time and place. It's perfectly acceptable, for instance, to ask "How do you feel?" if you're visiting a close friend in the hospital. But if the fellow is walking on both legs, hurrying to make a train, or sitting at his desk working, it's no time to ask him that silly question.

When George Bernard Shaw, the famous writer of plays was in his eighties, someone asked him "How do you feel", Shaw put him in his place. "When you reach my age", he said, "either you feel all right or you're dead."

1).According to the writer, greetings, such as "How do you feel?" _________ .

A. show one's consideration for others

2).The question "How do you feel?" seems to be correct and suitable when asked of ________ .

A. a man working at his desk

B. a person having lost a close friend

D. a friend who is ill

3).The writer seems to feel that a busy man should _________ .

A. be praised for his efforts

B. never be asked any question

C. not be bothered

D. be discouraged from working so hard

4).George Bernard Shaw's reply in the passage shows his ________ .

A. cheerfulness

B. cleverness

C. ability

D. politeness

5)."You've put a bug in his ear "means that you've _________ .

A. made him laugh

B. shown concern for him

C. made fun of him

D. given him some kind of warning

If you are like most people, your intelligence varies from season to season. You are probably a lot sharper in the spring than you are at any other time of the year. A well-known scientist, Ellsworth Huntington (1876-1937), concluded from other men's work and his own among people in different climates that climate and temperature have a definite effect on our mental abilities. He found that cool weather is much more favorable for creative thinking than summer heat. This does not mean that all people are less intelligent in the summer than they are during the rest of the year. It does mean, however, that the mental abilities of large numbers of people tend to be lowest in the summer.

Spring appears to be the best period of the year for thinking. One reason may be that in the spring man's mental abilities are affected by the same factors that bring about great changes in all nature. Fall is the next-best season, then winter. As for summer, it seems to be a good time to take a long vacation from thinking!
