Have you ever dreamed of traveling in space？ It was impossible a hundred years ago, nor was it 50 years ago. With the coming of the Space Age, man’ s dream of visiting the moon has come true.
The journey to the moon has been the first step towards future explorations in space. The distance between the moon and the Earth is very short indeed when compared with the distances between Earth and the other planets. Mars, the nearest planet to Earth is of miles away ! Traveling to the planets or travels between planets will be man’ s next aim. Such travels will be more difficult than the trip to the moon and certainly more exciting.
Recently, two American unmanned spacecraft, Vikings 1 and 2, landed on Mars in an attempt to discover whether that planet had any life on it. So far the presence of life on Mars has neither been proved nor ruled out. Russian space-probes have discovered that the surface of Venus is so hot that it is almost certain that there is no life there. Also the atmosphere of Venus is extremely, dense and the pressure is nearly a hundred times greater than the pressure of the Earth’s atmosphere.
Scientists believe that in the future, space stations can be built in space. These stations can act as stop-over points in space. Spacecraft can refuel at these stations and get their supply of air, food and water.
Spaceships of the future will be bigger and faster. They will be able to carry passengers for trips to the moon or planets.
Man may in the future find planets which have the same conditions as those we have on Earth, and make them his home. However such a possibility is still in the distant future. At the same time, Man should realize that the Earth will be his only home for a long time and begin to value and care for it.
Which of the following statements is true？
A．Recently, two American astronauts have landed on Mars.
B．The surface of Mars is very hot.
C．The journey to the moon started the future exploration in space.
D．There is life in Venus.

The industrial societies have been extremely productive during the last two centuries. The economic advance has been remarkable. During this relatively short period of time, greater changes in people's living conditions have occurred than in the thousands of years which preceded.
During the past 200 years the world population has increased 6 times, the annual world output has increased 80 times, and the distance a person can travel has gone up 1,000 times. There has also been much recent progress in art, culture, learning, and science. Such changes have led to a high rate of production and growth of the economy.
Economists fear that within the next 100 to 150 years, the earth's resources will become very scarce. Their fears are partly justified, but we should not be afraid. Industrial civilization adapts to new knowledge. By advancing knowledge, we not only create new forms of resources, but we also find ways to economize their use. Advanced modern knowledge can feed the hungry people of the world and improve their standard of living.

听力原文：Why are college students so prone to sleep deprivation？ The problem often begins during the teen years. Most high school kids admit that they are often sleepy and 15 percent admit that they fall asleep in class.
Lack of sleep causes many problems, not the least of which is the difficulty it adds to learning. It's also detrimental to the immune system and motor skills. Students (and everyone else) need at least eight hours of sleep to maintain optimum health and learning capabilities. Yet, with the pressure of school, family and social life, few students are sleeping near the required amount.
College life only escalates the problem. Added to the above activities are more hours needed for studies. Some students also hold down a part time job to help defray college expenses. Some students are married and trying to support a family. Because of all these pressures there is also an increase in stress. Stress can lead to insomnia and even more lost sleep.
With the approach of finals, the problem can only grow worse. Students force themselves to stay awake to study. It's called cramming for exams, and it can eat away at sleep hours already far too meager. Too many nights of forced wakefulness can eventually lead to a case of full-blown insomnia and other sleep abnormalities.
