听力原文： In a way, all of us are on a spaceship, the planet Earth. We move around the sun at 18 miles per second and never stop. On our spaceship we have five billion people and a limited supply of air, water, and land. These supplies have to be used carefully because we can't buy new air, water, or land from anywhere else.
The environment on our planet is a closed system Nothing new is ever added. Nature recycles its resources. Water, for example, evaporates and rises as visible drops to form. clouds. This same water returns to the earth as rain or snow. The rain that falls today is actually the same water that fell on the land 70 million years ago.
Today, the Earth is in trouble. Factories pour dirty water into our rivers. Many fish die and the water become unhealthy for people to drink. Cars and factories put poisons into the air and cause plants, animals and people to get sick. People throw bottles and paper out of their car windows, and the roadside becomes covered with all sorts of wastes. Over the years, people have changed the environment, and we have pollution.
To continue to survive, we must learn how to use the Earth's resources wisely. We have to change our habits and stop dumping such enormous amounts of industrial waste into the water and air. We must cooperate with nature and learn better ways to use, not to abuse, our environment.

Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
Earthquakes may rightly be ranked as one of the most destructive forces known to man: since records began to be written down, it has been estimated that earthquakerelated fatalities have numbered in the millions, and that earthquakerelated destruction has been beyond calculation. The greater part of such damage and loss of life has been due to collapse of buildings and the effects of rockslides, floods, fire, disease, tsunamis (gigantic sea waves), and other ob servable events resulting from earthquakes, rather than from the quakes themselves.
The great majority of all earthquakes occur in two specific geo graphic areas. One such area covers the Pacific Ocean and its bordering landmasses. The other extends from the East Indies to the Atlas Mountains, including the Himalayas, Iran, Turkey, and the Alpine regions. It is in these two great belts or zones that ninety percent of all earthquakes take place; they may, however, happen anywhere at any time.
This element of the unknown has for centuries added greatly to the dread and horror surrounding earthquakes, but in recent times there have been indications that earthquake forecast may be possible. By analyzing changes in animal behavior, patterns of movements in the earth's shell, variations in the earth's force of attraction, and the frequency with which minor earth shakes are observed, scientists have shown increasing success in expecting when and where earth quakes will strike. As a result, a worldwide earthquake warning net work is already in operation and has helped to prepare for (and thus lessen) the vast destruction that might otherwise have been totally unexpected.
It is doubtful that man will ever be able to control earthquakes and get rid of their destructiveness altogether, but as how and why earthquakes happen become better understood, man will become more and more able to deal with their possible damage before they occur.
Which of the following statements is TRUE according to the passage？
A．The actors and actresses are not paid for their performance.B．The actors and actress
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.
