Each day every person in the United States throws away more than five pounds of garbage(垃

Each day every person in the United States throws away more than five pounds of garbage(垃圾). There is more garbage now than ever before and most of it is made up of the packages and cans in which we put our food. The traditional way of getting rid of solid wastes is quickly becoming inadequate. Many cities are experimenting with newer ways of handling their growing piles of garbage.

One of these new ways is "recycling"(回收使用). Through recycling usable materials are taken out of garbage and made into something else. These usable parts of garbage are put through the cycle of going from a raw material to a finished product again.

In some cities a machine called Hydrapulper is being used to help recycle garbage. A Hydrapulper is like a huge mixing machine. The garbage is dropped onto a conveyor belt (传送带) that feeds the machine. At the same time, water is pumped into the Hydrapulper. With a mixing action, the Hydrapulper throws out the heavy metal objects that can later be sold as waste metal. The rest of the garbage—paper, food, plastic, rubber, glass, wood, leaves, and other items—falls apart. The waste is then mixed with water and carried to another piece of equipment where glass, sand and small pieces of metal are thrown out.

With the Hydrapulper, up to 95 percent of the original garbage is made again useful. The rest turns into furnace ash(炉灰).

Traditionally, garbage is thought to be ______.

A.a worthless burden to big cities

B.something that can be reused

C.a raw material for making new products

D.able to be recycled but difficult to handle

第3题

Fifty volunteers were alphabetically divided into two equal groups. Group A is to partic
ipate in a 7-week exercise program and Group B is to avoid planned exercise of any sort during those 7 weeks. On the day before the exercise program began, all 50 men participated in a step-test. This consisted of stepping up and down on a 16-inch bench, at 30 steps a minute for 5 minutes. One minute after completion of the step-test, the pulse rate of each subject (被测试者 ) was taken and recorded. This served as the pretest for the experiment. For the next 7 weeks, subjects in Group A rode an Exercycle (机器脚踏车 ) for 15 minutes each day, while Group B remained doing no planned exercises.At the end of the 7 weeks, the step-test was again given to both groups of subjects, and their pulses taken. The post-exercise pulse rates of subjects in the experimental were found to have decreased an average of 30 heart beats per minutes, with the lowest decrease 28 and the highest decrease 46. The pulse rates of subjects in the control group remained the same or changed no more than 4 beats, with an average difference between the initial and final tests of zero.

Passage Four Every culture and every country in the world celebrates New Year, but n

Passage Four

Every culture and every country in the world celebrates New Year, but not everyone does it the same way. The countries in North America and Europe welcome New Year on January the first. This practice began with the Romans in the Middle East, New Year is when spring begins. People in China and Vietnam celebrate it on the first day of the Spring Festival, which is the first day of their calendar based on the moon. Rosh Hashana, which is the Jewish (犹太人的) New Year, comes at the end of summer. The Hindus (印度教教徒 ) in India celebrate the first day of each season, so they have four New Years.

In all these cultures, there is a practice of making noise. People made noise in ancient times to drive away the evil spirits (妖精) from their homes. Today making noise is more of a custom than a religious rim

In the United States, many people stay up until midnight on New Year's Eve to watch the clock pass from one year to the next. Friends often gather together at a party on New Year's Eve, and when the new year comes, all ring bells, blow' whistles, sing songs, and kiss each other. A favorite Scottish song which everyone sings together is Auld Lang Sync. The words tell of old friends and good times.

In all cultures, New Year's Day is a time when people think of new beginnings. They want to make the coming year better than the last one. Many people in the United States make New Year resolutions. These are specific promises that they make to improve their behavior, change their habits, and become better people. There are many jokes about how a person keeps his or her New Year resolutions.

48. In ancient times, the practice of making noise was meant ______.

A. to keep the evil spirits away

B. to have fun

C. to celebrate the coming of the new year

D. to keep to a custom

Part A

Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D. (40 points)

Every living thing has an inner biological clock that controls behavior. The clock works all the time; even when there are no outside signs to mark the passing of time. The biological clock tells plants when to form. flowers and when the flowers should open. It tells insects when to leave the protective cocoon and fly away. And it tells animals when to eat, sleep and wake. It controls body temperature, the release of some hormones and even dreams. These natural daily events are circadian rhythms.

Man has known about them for thousands of years. But the first scientific observation of circadian rhythms was not made until 1729. In that year a French astronomer, Jean Jacques d’Ortous de Mairan, noted that one of his plants opened its leaves at the same time every morning, and closed them at the same time every night. The plant did this even when he kept it in a dark place all the time.

Later scientists wondered about circadian rhythms in humans. They learned that man’s biological clock actually keeps time with a day of a little less than 25 hours instead of the 24 hours on a man-made clock.

About four years ago an American doctor, Eliot Weitzman, established a laboratory to study how our biological clock works. The people in his experiments are shut off from the outside world. They are free to listen to and live by their circadian rhythms. Dr. Weitzman hopes his research will lead to effective treatments for common sleep problems and sleep disorders caused by ageing and mental illness.

The laboratory is in the Montefiore Hospital in New York City. It has two living areas with three small rooms in each. The windows are covered, so no sunlight or moonlight comes in. There are no radios or television receivers. There is a control room between the living areas. It contains computers, one-way cameras and other electronic devices for observing the person in the living area. A doctor or medical technician is on duty in the control room 24 hours a day during an experiment. They do not work the same time each day and are not permitted to wear watches, so the person in the experiment has no idea what time it is.

In the first four years of research, Dr. Weitzman and his assistant have observed 16 men between the ages of 21 and 80. The men remained in the laboratory for as long as six months. Last month, a science reporter for “The New York Times” newspaper, Dava Sobel, became the first woman to take part in the experiment. She entered the laboratory on June 13th and stayed for 25 days. Miss Sobel wrote reports about the experiment during that time, which were published in the newspaper.

We can conclude from the first paragraph that

A.every creature has an inner biological clock.

B.the biological clock works day and night.

C.the biological clock has circadian rhythms.

D.the biological clock regulates behavior. of creatures.

On the fourth Thursday of November, every year, Americans celebrate Thanksgiving Day. The
day is a national holiday which is set aside each year as a time to give thanks to God for our blessings (祝福).

Legend has it that the first English colonists (殖民者) in Massachusetts (马萨诸塞州) started the custom. According to the story, the Pilgrims~ first winter in the New World was difficult. They had arrived too late to grow many crops, and without fresh food, half of the colonists died from disease. The following spring the Indians taught them how to grow corn. In the autumn of 1621, bountiful crops of corn, beans and pumpkins were harvested. The colonists had much to be thankful for, so a feast was planned. They invited their Indian friends to join them in a large feast to share in the bounties (慷慨) of the land. This is the first Thanksgiving.

The traditional foods of the big Thanksgiving Day meal include roast turkey, cranberries, sweet potatoes, pumpkin pie, and Indian bread puddings.

Since the day is set aside for giving thanks, it has also become a traditional family day. Large dinners with many relatives are common throughout America on this special day.

When was the Thanksgiving Day tradition begun?

A.In the 17(上标)th century.

B.On Thursday.

C.Last November.

D.In the 16(上标)th eentury.

Directions: There are five reading passages in this part. Each passage is followed by five
ques- tions. For each question there are four suggested answers marked A, B, C and D. Choose one best answer and blacken the corresponding letter on the Answer Sheet.

Passage One

Walking through the dry leaves on his way home, Pat thought of what a bad day in school it had been. But every day was a bad day for him; he and the school did not like each other. But now that he was in the forest, Pat began to feel more like his usual self. He stopped to look at the quick moving stream of water called the Totopotomy. This little river was named for a man Pat liked, Totopotomy chief of the friendly Paumunkey Indians. He had heard stories about boys caught by the Paumunkeys who, when they were free, did not want to go home. Pat could understand how they felt. They did not have to go to school; they lived in the fresh air, and went fishing and hunting. How wonderful that must be!

The gentle sounds of a bird singing could be heard through the trees. Pat looked up, and tried to make the same sound. Uncle Langloo had told him to try and learn the language of the birds, and he was trying. Pat wanted to be like his uncle in every way. Langloo Win- ston was a hunter who spent most of his time living with the Indians. He fished with them, talked with them, even dressed like them, and the Indians loved him.

When Pat reached home, a young slave named Caesar ran out to meet him. Pat gave him a friendly push, and both boys rolled in the red earth. Caesar's job was to serve Pat, but he was more friend than servant. Even as a boy, Pat Henry did not believe in such differences between men.

36. The Paumunkeys did all the following except ______.

A. not having to go to school

B. living in the fresh air

C. going fishing and hunting

D. not wanting to go home

Part A

Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D. Mark your answers on ANSWER SHEET Ⅰ.

Text 1

Populations tend to grow at an exponential rate. This means that they progressivel, double. As an example of this type of growth rate, take one penny and double it every day for one month. After the first week, you would have only 64 cents, but after the fourth week you would have over a million dollars.

This helps explain why the population has come on "all of a sudden". It took from the beginning of human life to the year 1830 for the population of the earth to reach one billion. That represents a time span of at least two million years. Then it took from 1830 to 1930 for world population to reach 2 billion. The next billion was added by 1960, only thirty years, and in 1975 world population reached 4 billion, which is another billion people in only Fifteen years.

World population is increasing at a rate of 9,000 per hour, 220,000 per day, 80 million per year. This is not only due to higher birth rates, but to lower death rates as well. The number of births has not declined at the same rate as the number of deaths.

Some countries, such as Columbia, Thailand, Morocco, Costa Rica, and the Philippines, are doubling their populations about every twenty - one years, with a growth rate of 3.3 percent a year or more. The United States is doubling its population about every eighty-seven years, with a rate of 0.8 percent per year. Every time a population doubles, the country involved needs twice as much of everything, including hospitals, schools, resources, food and medicines to care for its people. It is easy to see that this is very difficult to achieve for the more rapidly growing countries.

21. This passage chiefly discusses ______.

A) the growth of world population

B) one type of the exponential rate

C) the population problem of more rapidly growing countries

D) the possible ways of dealing with the rapid population growth
