Time in the Animal World
Rhythm controls everything in Nature.(46)
The sun provides a basic time rhythm for all living creatures including humans. Nearly all animals are influenced by sun cycles and have developed a biological clock in their bodies following these cycles. The moon also exerts its force and influence on the sea. Its gravitational attraction causes the rising of the tide.(47)When the moon is behind the Earth, centrifugal force causes the second tide of the day.
Animals living in tidal areas must have the instinct of predicting these changes, to avoid being stranded and dying of dehydration. Since the time of the dinosaurs, the king crab has been laying eggs at the seaside in a set way. To avoid predator fish, the eggs are always far from seawater and protected by sand. In the following two months, the eggs undergo dramatic changes related to the cycles of the moon. When the second spring tide comes, the young king crabs have matured.(48)
Most of the mammals, either the giant elephant or the small shrew, have the same average total number of heartbeats in their lifetime. Shrews live only for two and a half years, and spend their life at a high speed and high tempo. Animals like shrews with a pulse rate of 600 per minute have an average total of eight hundred million heartbeats throughout their life. The African elephant has a pulse rate of 25 beats per minute, and a life span of 60 years. The size of the body determines the speed of life.(49)
As we get older, our sense of time is being influenced by the physiological changes of our body. The elderly spend more time resting, and do few sports.(50)For a child, a week is seen as a long time.
A. For an adult, time goes fast year by year.
B. It controls, for example, the flapping of birds' wings, the beating of the heart and the rising and setting of the sun.
C. The larger the animal is, the longer its life span is and the slower its life tempo is.
D. The tide goes out when the moon moves away and its attraction is weaker.
E. We always tend to think all the animals have the same sense of time as human beings.
F. The second spring tide takes them back to the sea.

听力原文： For all its benefits, television's influence has been extremely harmful to the young. Children do not have enough experience to realize that TV shows present an unreal world; that commercials lie in order to sell products that are sometimes bad or useless. They believe and want to imitate what they see. They do believe that they will make more friends if they use a certain soap, or some other product. By the time they are out of high school, most young people have watched about 15,000 hours of television, and have seen about 18,000 killings or other acts of violence. How could they be choked to see the same in real life？ All educators and psychologists agree that they "television generations" are more violent than their parents and grandparents. It is certain that television has deeply transformed our lives and our society. It is certain that, along with its benefits, it has brought enormous problems. To those problems we must soon find a solution because—whether we like it or not—television is here to stay.
(33)
A．Television's bad effects on the young.
B．Television's bad effects on society in general.
C．The history of television.
D．The good sides of television.

听力原文： Crime has its own cycles，a magazine reported some years ago. Police records show a surprising relation between changes in the season and crime patterns.
The pattern of crime has changed very little over a long period of years. Murder reaches its high during July and August，as do other violent attacks. Murder，in addition，is more than seasonal；it is a weekend crime. It is also a nighttime crime: 62 percent of murders are committed between 6 P. m. and 6 a. m. One is most likely to be robbed between 6 P. m. and 2 a. m. on a Saturday night in December，January，or February. Except for one strange statistic，May is the least criminal month of all.
Apparently our intellectual season cycles are completely different from our criminal patterns. Professor Huntington made a lot of studies to discover the seasons when people read serious books，attend scientific meetings，and make the highest scores on examinations. In all examples，he found a spring peak and an autumn peak separated by a summer low. On the other hand，Professor Huntington's studies showed that June is the peak month for suicides and for admitting patients to mental hospital. June is also a peak month for marriages!
Possibly，high temperature and humidity bring on our strange and surprising summer actions，but police officers are not so sure. “There are，of course，no proof of a relation between humidity and murder”，they say. “Why murder's high time should come in the summer time we really don't know”.

Unlike the summer high in crimes of bodily harm, robbing has a different cycle. You are most likely to be robbed between 6 p.m. and 2am. on a Saturday night in December, January, or February. The month with least crimes of all is in May except for one strange fact. More dog bites are reported in this month than in any other month of the year.
Clearly our seasonal cycles of knowledge are completely different from our tendencies for crimes. Professor Huntington made extensive studies to discover the seasons when people read serious books, attend scientific meetings and get highest results on examinations. In all cases, he found a spring high and autumn high separated by a summer low.
Possibly, high temperature and high humidity(湿度)cause our strange and violent summer actions, but police officials are not sure. "There is, of course, no proof of a connection between humidity and murder," they say," Why murder's high time should come in the summer time we really don't know."
A good title of the passage would be ______.
A．Crime Cycles
B．Summer Crimes
C．A Time for Murder
D．The Most Peaceful Month

听力原文： Strikes are very common in Britain. They are extremely harmful to its industries. In fact there are other countries in Western Europe that lose more working days through strikes every year than Britain. The trouble with the strikes in Britain is that they occur in essential industries. There are over four hundred and ninetyfive unions in Britain. Some unions are very small. Over twenty have more than one hundred thousand members. Unions do not exist only to demand high wages. They also educate their members. They provide benefits for the sick and try to improve working conditions. Trade unionists say that we must thank the unions for the great improvement in working conditions in the last hundred years. It is now against the law fur union members to go on strike without the support of their union. This kind of strike la called the unofficial strike and was common until recently. Employers felt that unofficial strikes were most harmful because they could not be predicted. However, these unofficial strikes still occur from time to time and some unions have also refused to cooperate with the law. As a result, the general picture of the relations between workers and employers in Britain has gone from bad to worse.
(23)
A．They often take place in the major industries.
B．British trade unions are more powerful.
C．There are more trade union members in Britain.
D．Britain loses more working days through strikes every year.
