But which one is better?The rapid reader may be a good reader when he reads a storybook for fun. But he may not be able to slow down enough to read directions(说明) carefully. He may read so rapidly that he does not take time to understand fully the ideas and information which are important to remember.The slow reader may be a good reader when he reads directions for making something. But he may spend too much time in reading a simple story which is meant to be enjoyed but is not important enough to be remembered.So, you see, either a rapid reader or a slow reader is not really a good one. If you wish to become a better reader, here are four important things to remember about speed of reading.1. Knowing why you are reading will often help you to know whether to read rapidly or slowly.2. Some things should be read slowly throughout. Examples are directions for making or doing something, science and history books, and Maths problems. Y ou must read such things slowly or remember each important step and understand each important idea.3. Some things should be read rapidly throughout. Examples are simple stories for enjoyment, letters from friends and bits of news from hometown papers.4. In some of your reading, you must change your speed from fast to slow and slow to fast, as you go along. Y ou will need to read certain(某些) pages rapidly and then slow down and do more careful reading when you come to important ideas.31. What should be read rapidly?A. Directions for making something.B. Maths problems.C. Science and history books.D. Storybooks, newspapers, personal letters, etc.32. What is the important thing you should keep in mind about speed of reading?A. To read as fast as you can.B. To fit your reading speed to your needs.C. To read as slowly as possible.D. To keep your reading at a certain speed.33. Which title best gives the main idea of the passage?A. Something about Careful ReadingB. Be a Rapid Reader.C. How to Read?D. How to Be a Slow Reader?BGood evening, ladies and gentlemen. Wel come to the nine o’clock Mystery Hour. Today we’ll show you two British stories. We hope you’ll enjoy them.About 900 years ago two green children arrived in a small village in south England. Their eyes and skin were green and they spoke a strange language. They were very tired and weak, so the people of the village looked after them. The boy died a year later, but the girl grew strong and lived the rest of her life there. And her skin colour turned back to normal day by day. Scientists say that sometimes o f people don’t have enough food to eat for a long time, their skin goes very pale and can even turn green.Loch Ness is the largest lake in Scotland. It’s a very deep and cold lake. For hundreds of years, people have talked about a monster(怪物) called Nessie which lives in the lake. About seventy years ago, two people saw something moving in the lake. They said that the animal was playing and rolling around in the water. Since then many people say they have seen the monster. Their descriptions are always the same. It looks like a dinosaur, with a very long neck and a small head. It has a big bump(包,肿块)on its back. People have tried to photograph the animal, but the pictures have not been very clear. Scientists don’t know whether there is a monster or not. Som e say it may be a whale or a very large fish. Some think it’s a snake. Others say there’s nothing at all— nothing but people’s imagination. Maybe we’ll never know what’s in Loch Ness.34. What kind of story is talked about in this programme?A. Romantic stories.B. Mysteries.C. Horror stories.D. Comedies.35. Which sentence is TRUE about the two green children?A. They both enjoyed a long and happy life.B. The girl’s eyes and skin were green all her life.C. At first they spoke the same language as people in the small village did.D. Maybe they hadn’t eaten enough for long before they reached the village.36. What does Nessie look like according to some witnesses?37. What can we learn from the second story?A. Scientists are still not sure whether there is a monster or not in Loch Ness.B. Loch Ness is very deep and warm lake in Scotland.C. People have taken very clear pictures of Nessie.D. In fact Nessie is a whale or a snake.CClose contacts between Japan and the rest of the world were created in the twentieth century. In the last forty years, business contacts between Japan and the West have become very important. Many foreign companies now have offices in Japan and Japanese businessmen do business around the world. Differences between Japanese and Western ways of doing business, however, often bewilder foreign businessmen and make doing business in Japan difficult for foreigners.The American businessman, for example, wants to start talking business immediately. He does not want to wait. The Japanese businessman, on the other hand, likes to arrive at decisions after giving them serious thought. Another thing foreign businessmen have difficulty in understanding is when a Japanese means “Y es” or “No”. This is because of cult ural differences between Japanese and Western society(社会), Which make it difficult for a Japanese to say “No” directly.In the USA, it is easy to say “No” to something one does not want to do. But in Japan, it is very difficult to say “No”. To refuse an invitation or a request(请求) with “No” is felt to be impo lite. It is thought to be selfish and unfriendly. So instead of saying “No” directly, the Japanese have developed many ways to avoid(避免) saying “No”. These can help them avoid hurting other people’s feelings. However, this often makes their ways of doing b usiness rather difficult for foreigners to understand and follow.38. What often makes foreigners feel difficult to do business in Japan?A. Their different ways of doing business.B. Their different lifestyles.C. The fact that the Japanese never say “No”.D. The fact that the Japanese are slow to take action.39. Which of the following is the closest in meaning to the underlined expression “bewilder foreignbusinessmen” in Paragraph One?A. cause foreign businessmen to change their minds.B. give a feeling of surprise to foreign businessmen.C. attract foreign businessmen’s attention.D. make foreign businessmen think wrongly.40. What fact does the passage lead you to believe?A. American businessmen do things more slowly than Japanese ones.B. American businessmen like to say “Y es” and “No”.C. Americans usually say what they are thinking.D. Americans do not say what they think or feel clearly.41. From the passage we can infer(推断) that __________.A. Japanese businessmen are good at businessB. foreign businessmen should try to know Japanese ways of doing businessC. foreign businessmen must be more politeD. you must learn from Japanese businessmen if you want to succeed四.词汇运用:1.
