Directions: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.
听力原文： A good marriage means growing as a couple but also growing as individuals. It isn't easy; marriage bas always been difficult. Why then are we seeing so many divorces at this time？ Yes, our modern social fabric is thin, and yes, the permissiveness of society has created unrealistic expectations and thrown die family into disorder. But divorce is so common because people today are unwilling to exercise the self-discipline that marriage requires. They expect easy joy, like the entertainment on TV, the thrill of a good party.
Marriage takes some kind of sacrifice, not dreadful self-sacrifice of the soul, but some level of compromise. Some of one's fantasies, some of one's legitimate desires, have to be given up for the value of the marriage itself. "While all martial partners feel shackled at times, it is they who really choose to make the martial ties into confining chains or supporting bonds," says Dr. Walter. Marriage requires sexual, financial and emotional discipline. A man and a woman cannot follow every impulse, cannot allow them to stop growing or changing.
Why are divorces so common at present？
A．Because it is difficult to maintain a marriage.
B．Because people like watching TV programs.
C．Because people prefer joy to self-discipline.
D．Because our society is permissive towards divorces.
SECTION B PASSAGES

听力原文： It is a dark stormy night when suddenly the phone rings. I casually answer the telephone. It is my older sister informing me that our mother is in the hospital. She is going to need an emergency brain transplant. It takes me just a moment to drop everything I am doing and rush to the hospital. When I arrive I see my father and sister in the waiting room casually enjoying their conversation. I am amazed they could have such high spirits at such a time. As I begin to confront them on this, they inform. me that this is merely a routine brain transplant. They reinforce that very few die from the actual transplant. I become immediately relieved as a huge burden has been lifted off my shoulders. Issues of transplants, vaccines, and medicine are such that, whether anyone realizes it, they are becoming a social concern that does affect each of us. Nearly each and every one of us today has received vaccine shots. We have all used medications. We have all heard of transplant technology. This above example I have used is farfetched. Brain transplants are not an everyday occurrence. They are not yet, at least. However, kidney and heart transplants are beginning to become a more and more common every day. Who knows what is possible with the proper research.
Why did the speaker drop everything at the time？
A．Because she received a telephone call at midnight.
B．Because her mother was sent to a hospital.
C．Because her older sister was seriously ill.
D．Because her father was sent to a hospital.
A.Because they are short of food
B.Because they feed on white rice
C.Because white rice contains no vitamin
D.Because white rice has no nutrients
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.
(33)

B．Because the Earth moves around the sun as fast as a spaceship.
