Part A<br>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.<br>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.<br>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.<br>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.<br>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.<br>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.<br>How many new materials are mentioned in this passage？

A. Two.
B. Three.
C. Four.
D. Five.

Part B<br>Directions: You will hear 3 conversations or talks and you must answer the questions by choosing A, B, C or D. You will hear the recording ONLY ONCE.<br>听力原文： When a consumer finds that all itern she or he bought is broken or in some other way does not reach the standard of the manufacturer's claim for it, the first step is to present the warranty. or any other records which might help, at the store of purchase. In most cases, this action will produce results. However, if it does not, there are various means the consumers may use to gain satisfaction.<br>A simple and common method used by many consumers is to complain directly to the store manager. In general, the“higher, up”the consumer takes his or her complaint, the faster he or she can expect it to be tackled. In such a case, it is usually settled in the consumer's favor, assuming he or she has a just claim.<br>Consumers should complain in person whenever possible, but if they can not get to the place of purchase, it is acceptable to phone or write the complaint in a letter.<br>Complaining is usually most effective when it is done politely but firmly, and especially when the consumer can demonstrate what is wrong with the itern in question. If this cannot be done, the consumer will succeed best by presenting specific information as to what is wrong, rather than by making general statements. For example, “The left speaker does not work at all and the sound coming out of the right one is unclear”is better than“this stereo does not work”.<br>The store manager may advise the consumer to write to the manufacturer. If so, the consumer should do this, stating the complaint as politely and as firmly as possible. But if a polite complaint does not achieve the desired result, the consumer can go a stemp further. She or he can threaten to take the seller to court or report the seller to a private or public organization responsible for protecting consumers'rights.<br>When a consumer finds that his purchase has a fault in it, what is the first thing he should do？

A. Complain personally to the manager.
B. Threaten to take the matter to court.
C. Write a firm letter of complaint to the store of purchase.
D. Show some written proof of the purchase to the store.

Part A<br>Directions: You will hear a talk. As you listen, answer Questions 1-10 by circling TRUE or FALSE. You will hear the talk ONLY ONCE. You now have 1 minute to read Questions 1-10.<br>听力原文： Every year there are reports of people dying as the result of extremely hot weather．Many of the victims are old persons，whose hearts or breathing systems decline．But many die from lack of water．<br>Water is necessary for life and good health．We often forget this fact when we think about the other building blocks of life such as vitamins，minerals and proteins．We can live for many days without eating，but two or three days without water usually leads to death．<br>The human body may look solid．but most of it is water．New born babies are as much as 85% water．Women are about 65% water and men about 75%．Women usually have less water than men because women，in general，have more fat cells．and fat cells hold less water than other kinds of cells．<br>Water does many different things to keep us healthy．It carries hormones，antibodies and foods through the body，and carries away waste materials．That is why different parts of the body contain different amounts of water．For example．blood is 83% water．muscles are 75% water，the brain is 74%．and bones are 25%．<br>Water is also necessary for cooling the body under hot weather and when we are working hard or exercising，water carries body heat to the surface of the skin，where the heat is lost through perspiration．Researchers say cool liquids cool us faster than warm liquids，because cold liquids take up more heat inside the body and carry it away faster：They say，however，that cold sweet drinks do not work well because the sugar slows the liquid from getting into the blood-stream．<br>Researchers also note that fat cells block body heat from escaping quickly．Fat cells under the skin act like warm clothing to keep body heat inside．This is why overweight people have a more easy time staying cool than thin people．<br>The body loses water every day through perspiration and urine．If we lose too much．we will become sick．A 10% drop in body water can cause the blood system to fail．A 15%～20% drop usually leads to death．To replace what is lost，health experts say growing persons should drink about 2 liters of liquids each day，and more in hot weather．They say we can also get some of the water we need in the foods we eat．Most fruits and vegetables are more than 80% water．Meats are 50%～60% water．And even bread is about 33% water．Water may be one of the most simple of all chemical substances，but it is the most important substance that we put into our bodies．<br>Water is a kind of chemical substance.
