Part A
Directions: Read the following texts and answer the questions which accompany them by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1.
The Stone age, the Iron age. Entire epochs have been named for materials. So what to name the decades ahead？ The choice will be tough. Welcome to the age of superstuff. Material science--once the least sexy technology—is bursting with new, practical discoveries led by superconducting ceramics that may revolutionize electronics. But superconductors are just part of the picture: from houses and cars to cook pots and artificial teeth, the world will sometime be made of different stuff. Exotic plastics, glass and ceramics will shape the future just as surely as have genetic engineering and computer science.
The key to the new materials is researchers' increasing ability to manipulate substances at the molecular level. Ceramics, for instance, have long been limited by their brittleness. But by minimizing the microscopic imperfections that cause it, scientists are making far stronger ceramics that still retain such qualifies as hardness and heat resistance. Ford Motor Co. now uses ceramic tools to cut steel. A firm called Kyocera has created a line of ceramic scissors and knives that stay sharp for years and never rust or corrode.
A similar transformation has overtaken plastics. High-strength polymers now form. bridges, ice skating rinks and helicopter rotors. And one new plastic that generates electricity when vibrated or pushed is used in electric guitars, touch sensors for robot hands and karate jackets that automatically record each punch and chop. Even plastic litter, which once threatened to permanently blot the landscape, has proved amenable to molecular tinkering. Several manufacturers now make biodegradable forms; some plastic six-pack rings for example, gradually decompose when exposed to sunlight. Researchers are developing ways to make plastics as recyclable as metal or glass. What's more, composites—plastic reinforced with fibres of graphite or other compounds--made the round-the-world flight of the voyager possible and have even been proved in combat: a helmet saved an infantryman's life by deflecting two bullets in the Grenada invasion.
Some advanced materials are old standard with a new twist. The newest fiberoptic cables that carry telephone calls cross-country are made of glass so transparent that a piece of 100 miles thick is clearer than a standard window pane.
But new materials have no impact until they are made into products. And that transition could prove difficult, for switching requires lengthy research and investment. It can be said a firmer handle on how to move to commercialization will determine the success or failure of a country in the coming future.
How many new materials are mentioned in this passage？
Women have more fat cells so women have less water.

SECTION B INTERVIEW
Directions: In this section you will hear everything ONCE ONLY. Listen carefully and then answer the questions that follow. Questions 1 to 5 are based on an interview. At the end of the interview you will be given 10 seconds to answer each of the following five questions.
Now listen to the interview.
听力原文： An interview with Helena Norberg-Hodge, about her work in a pristine, ancient Himalayan culture as it faced the siren song of western-style. development. Share International US editor Monte Leach spoke with Norberg-Hodge on her recent visit to the San Francisco Bay Area.
Share International: How did you first get involved with helping to preserve the Ladakhi culture？
Helena Norberg-Hodge: I trekked into remote valleys and spoke to Ladalthi people everywhere. I saw quite a remarkable self-reliant wealth and above all an amazing self-esteem of people who were models of what it means to feel completely secure in their own identity and place. They seemed to be the most open, happy and humble people. And they told me they had never known hunger. They had a standard of living much higher than I would have expected, none of it from so-called progress.
SI: How did their way of life begin to be undermined？
HNH: The Indian Government had a territorial dispute with the Chinese, and decided to develop this area as a way of ensuring that it became a closer part of India. Their approach to development was based on a Western model which had nothing to do with local knowledge and resources, This included pushing chemical fertilizers and pesticides, including DDT and other outlawed pesticides. It meant subsidizing white rice and white sugar from the outside. These subsidies for imported food were destroying local food production, and creating a total dependence on imports. It was making the region very vulnerable. Subsidized fossil fuels like kerosene and coal being brought in to heat houses also led to subsidized transport. It meant that roads the government was building were actually destroying the local economy.
Tourism also became part of the Indian Government's plan to develop the area. Nearly every foreigner who came there was just amazed by how peaceful, happy and beautiful the place and people were. The foreigners would say: "Oh, what a paradise. What a pity it has to be destroyed." When I heard this for something like the 100th time, something within me snapped. I was closely involved with the local people, and I knew not a single one of them thought of this as destruction. Not a single local person ever said: "What a pity we have to be destroyed." I realized the foreigners had seen that in the rest of the world this type of economic growth could be very destructive. I also realized the local people knew nothing about it. Around that time I read a book called Small is Beautiful. It gave me the conviction that things could be done differently and meeting the outside world didn't have to mean destruction.
I started talking to the local people about what development had meant in other parts of the world. I realized they were getting a completely wrong view of what life was like in the West. They were saying: "My God, you must be incredibly wealthy." They were getting an impression that we never need to work, that we have infinite wealth and leisure. It is not that they were unintelligent, but they had limited information about this other world.
That led me to realize that I could do work which would provide more accurate information. My goal was not to tell the Ladakhis what to do, not even to tell them that they should stay exactly the way they were, but to provide as much information as possible on what life is really like in the West. That included information on our problems of pollution, unemployment, and poverty, and that a lot of the poverty in the so-called Third World was due to our wealth in the developed world. I also wanted to show that
