听力原文： The story of silk is a fascinating one. About 4,000 years ago the Chinese discovered the secret of the cocoon. No one knows exactly how or when this was made. One story says that a young princess was drinking tea in her garden and watching the silkworm spin cocoon. By chance one dropped into her tea, and the hot liquid softened it. When the girl tried to take the cocoon out of her tea. She pulled out a long silk thread.
The Chinese learned to weave the silk thread into cloth. For 2,000 years they were the only people who knew how to make silk. The Chinese merchants sold silk cloth throughout Asia and Europe and became rich. Silk was so expensive that it was called "the cloth of the Kings". Everyone wanted to learn how to make silk, but the Chinese kept the secret carefully guarded. Finally the secret was stolen. In the sixth century, two monks learned about the silk worms and their cocoons. They spent several years in China and finally found a way to take some worm eggs out of the country. The monks also carried bamboo canes. One day they hid some eggs in the hollow canes, and walked out of China with them. It is said that the development of the silk industry in other countries came from those few eggs which the monks had carried out of China.

听力原文： America is growing older. Fifty years ago, only 4 out of every 100 people in the United States were 65 or older. Today, 10 out of every 100 Americans are over 65. The aging of the population will affect American society in many ways — education, medicine and business.
Quietly, the graying of America has made us a very different society — one in which people have a quite different idea of what kind of behavior. is suitable at various ages. A person's age no longer tells you anything about his / her social position, marriage or health. There's no longer a particular year in which one goes to school or goes to work or gets married or starts a family. The social clock that kept us on time and told us when to go to school, get a job, or stop working isn't as strong as it used to be. It doesn't surprise us to hear of a 29-year-old university president or a 35-year-old grandmother, or a 70-year-old man who has become a father for the first time.
Public ideas are changing. Many people say, "I am much younger than my mother or my father was at my age". No one says "Act your age" anymore. We've stopped looking with surprise at older people who act in youthful ways.
Questions 29 to 31 are based on the passage you have just heard.
29. What is the percentage of people above 65 in America today？
30. What can we know from the passage？
31. What does the passage imply？
(30)
A．4%.
B．10%.
C．14%.
D．25%.
听力原文： Early one morning, more than a hundred years ago, an American inventor called Elias Howe finally fell asleep. He had been working all night on the design of a sewing machine but he had run into a very difficult problem; (29)it seemed impossible to get the thread to run smoothly around the needle. Though he was tired, Howe so, Howe ran into the salve problem as before. (29)The thread kept getting caught, around the needle. The king flew into the cage and ordered his soldiers to kill Howe. They came up towards him with their spears raised, hut suddenly the inventor noticed something. There was a hole in the tip of each spear. The inventor awoke from the dream, realizing that (30)he bad just found the answer to the problem. Instead of trying to get the thread to run around the needle, he should make it run through a small hole in the center of the needle. This was the simple idea that finally made Howe design and build the first really practiced sewing machine．(31)Elias Howe was not the only one who found the answer to his problem in this way. Thomas Edison, the inventor of the electric light, said his best ideas came into him in dreams. So did the great physicist Albert Einstein. Charlotte Bronte also drew in her dreams in writing Jane Eyre.
(30)
A．What kind of thread to use.
B．How to design a needle which would not break.
C．Where to put the needle.
D．How to prevent the thread from getting caught around the needle.

Do you know that we live a lot longer now than the people who were born before us？ One hundred years ago the average woman lived to be 45. But now， she can live until at least 80.
One of the main reasons for people living longer is that we know how to look after ourselves better. We know which foods are good for us and what we have to eat to make sure our bodies get all the healthy things they need.We know why we sometimes get ill and what to do to get better again. And we know how important it is to do lots of exercise to keep our hearts beating healthily.
But in order that we don"t slip back into bad habits， let"s have a look at what life was like 100 years ago.
Families had between 15 and 20 children， although many babies didn"t live long.Children suffered from lots of diseases， especially tickets （佝偻病 ） and scurvy （坏血病） ， which are both caused by bad diets. This is because many families were very poor and not able to feed their children well.
Really poor families who lived in crowded cities like London and Manchester often slept standing up，bending over a piece of string， because there was no room for them to lie down.
People didn"t have fridges until the 1920s. They kept fresh food cold by storing it on windowsills （窗台板 ） ， blocks of ice， or even burying it in the garden.
Some children had to start work at the age of seven or eight to earn money for their parents. If you had lived 100 years ago， you might well be selling matchsticks （火柴杆） （a job done by many children ） or working with your dad by now.

听力原文： Esperanto was invented as an international language one hundred years ago by a doctor in Poland. His name was Ludovic Zamenhof. Doctor Zamenhof grew up in a part of Poland where people spoke several different languages. He believed the different languages kept people from understanding each other and living peacefully together. He wished that everyone in his part of Poland spoke the same language. In fact, he believed that if everyone spoke a common language, peace could result throughout the world. That is why he gave the world a new language. He called it "Esperanto", which means, in his language "one who hopes."
Doctor Zamenhof tried to make Esperanto so easy that anyone could learn it in one-hundred hours. It is easy to learn because it has only sixteen grammatical rules. Doctor Zamenhof's alphabet is also simple. Each letter has only one sound.
No one knows exactly how many people in the world speak Esperanto. Experts say the number could be as many as fifteen million. For most of the world's people, however, English, not Esperanto, is the second language. But Esperantists continue to spread the world about their language. They hope that Esperanto someday will become the international language for trade, science, and diplomacy.
(26)
A．Different languages prevented people from living peacefully together.
B．Because he believed that people would prefer a new language.
C．Because he believed that people would favor an easy language.
D．Because he thought that his mother tongue was too difficult to learn.
听力原文： Modern zoos are very different from zoos that were built fifty years ago. At that time, zoos were places where people could go to see animals from many parts of the world.
The animals lived in cages that were made of concrete with iron bars, cages that were easy to keep clean. Unfortunately for the animals, the cages were small and impossible to hide in. The zoo environment was anything but natural. Although the zoo keepers took good care of the animals and fed them well, many of the animals did not thrive; they behaved in strange ways, and they often became ill.
In modern zoos, people can see animals in more natural habitats. The animals are given more freedom in large areas so that they can live more as they would in nature. Even the appearance of zoos has changed. Trees and grass grow in the cages, and streams of water flow through the areas that the animals live in. There are few bars; instead, there is often a deep ditch, filled with water, surrounding an area where several species of animals live together as they would naturally.
