APartComposition Writing（作文）20分略附录：Scripts for listening comprehension.Part I Listening ComprehensionSection A Spot DictationDirections：In this section, you will hear a short passagetwice.While listening, you are required to fill in the blanks with the exact words you have just heard.Please write your answers on your Answer Sheet.Pandas have five toes or digits on each foot. But the front paws have a sixth digit made from an enlarged wrist bone. Scientists call this the pandas thumb .That thumb works, Dr. Gould admits, but it is clumsy. In his opinion, it would win no prizes in a design competition. It is one of those odd arrangements and funny solutions we might expect from evolution, but not from God.Funny, isnt it, how we humans think we have everything figured out, and then we learn that we dont. While Dr. Gould was writing about what he believed was the terribly poor design of the pandas thumb, and how it wouldnt win any awards for good design, other scientists were performing important research on that very thumb. And what did their research show? The pandas thumb now has been found to exhibit intricate design that is very important to the pandas existence.Section B Short DialoguesDirections：In this section, you will hear 6 short conversations. At the end of each conversation a question will be asked about what was said. Each conversation and question will be spokenonly once. After each question there will be a pause. During the pause, you must read the four choices marked A), B), C), and D). Then you should decide on the best choice andwrite down the corresponding letter on the Answer Sheet.1.

Lets try to talk some sense into her.Q: What are the speakers probably going to do?2. W: Mary, do you believe in UFOs?W: Me? Well, I have never seen one. But there are a lot of people who have, or who think they have seen one.Q: What can we learn about Mary?3. W：You know, I started out in civil engineering. Then I switched to electronic engineering. But what really interests me is electronic music.W: Wow, thats a long way from civil engineering.Q: Which of the following has the woman never been interested in?4. W: I bought a pint of milk for our breakfast. But it doesnt seem to look fresh now. Do you think it is still alright to drink?W: Let me smell it. Well, it has gone off. If I were you, I wouldnt even think of it.Q:What does the woman mean?5. W: Is it true that all of them survived the fire last night?W: Yes, a miracle, isnt it? There was a couple on the second floor and two women and three kids on the ground floor. But no one was badly hurt.Q: How many people were caught in the fire?6. W: Im going to take the blood test at 7:45 tomorrow morning.W: In that case, you wont miss any courses tomorrow morning then.Q: What can we learn from the conversation?Section C Short PassagesDirections：In this section you will hear two short passages.At the end of each passage you will hear three questions.Both the passages and questions will be spokenonly once.After you hear a question you must choose the best answer from the four choices marked A), B), C), and D).Then write down the corresponding letter on the Answer Sheet.Passage 1Wash your hands. Brush your teeth. Scrub the toilet. Do the dishes. Being clean is supposed to keep us healthy by destroying bacteria that make us sick.But our attention to cleanliness might have a down side. New research suggests that the chemicals we use to clean and disinfect could be damaging the environment by killing off algae at the base of the food chain.Over the past decade, the war against bacteria has been stepping up. From dish soap to toothpaste, cleaning products have become increasingly deadly to the tiny troublemakers. After getting dumped down the drain, those household chemicals usually go straight through the sewer system and into lakes and streams, ignored by wastewater treatment plants.Questions 7 to 9 are based on the passage you have just heard.7: In what way can being clean keep us healthy?8: What does the new research suggest?9: What kind of cleaning products can be damaging to bacteria?Passage 2Is it possible to slow down or speed up time? Yes, it is. The theory of relativity treats time as the fourth dimension, which has a barrier the same as any other force. It is also stated that the time barrier can be broken if the speed of light is achieved. How can we make this really happen? According to the theory, to achieve the speed of light, you need to have an
