English is more important now. Almost everyone knows that we should learn English well. But it is difficult for many students to learn it well. Now I make some suggestions, maybe they can help you learn it well. If you want to become a fluent English speaker, you should take some advice. There are four skills in learning English. They are reading, listening, speaking, and writing. The most important thing you must remember is that if you want to improve your speaking and writing skills, you should first master the skills of reading and listening. Read as much as you can. But your reading must be active. It means that you must think about the meaning of the sentence, the meaning of the unfamiliar words, etc. There is no need for you to pay much attention to grammars or try to understand all the unfamiliar words you come across, but the fact that you see them for the first time and recognize them whenever you see them, for example, in other passage or books, is enough. It would be better to prepare yourself a notebook so you can write down the important words or sentences in it. As for listening, there are two choices: besides reading, you can listen every day for about 30 minutes. You can only pay attention to your reading and become skillful at your reading, then you can catch up on your listening. Since you have lots of inputs in your mind, you can easily guess what the speaker is going to say. This never means that you should not practice listening. For listening you can listen to cartoons or some movies that are specially made for children. Their languages are easy. Or if you are good at listening and preferably taking some notes. Speaking is different among the four skills in learning English. The other three you can do alone on your own, but you can’t really speak alone. Then how can you practice speaking? Where can you find people to speak English with? There is a saying: practice makes perfect. That is to say, we should talk with our partners in English as much as we can. At school you should use the chance to speak. If your teacher asks you to speak in pairs with other students, try to say as much as possible. Don’t worry about your mistakes. Just speak! If you follow these pieces of advice, your speaking and writing will improve automatically, and you can be sure that with a little effort they will become perfect. 69. According to the author, which should you improve first among the four skills? A. Reading and listening B. Reading and Writing C. Writing and speaking D. Speaking and listening 70. The underlined phrase “come across” in Paragraph 3 can probably be replaced by “_______”. A. meet by accident B. discover out C. find on purpose D. look for 71. To improve your reading, when you read you should ______________. A. look up all the new words in the dictionary B. think about what you are reading actively C. spend more time studying grammars D. copy as many words and sentences as possible 72. The author seems to agree with the view that _____________. A. Everyone should listen to VOA or BBC programs every day. B. you needn’t practice listening if you keep on reading every day. C. being good at reading is helpful in improving your listening. D. you should take notes of whatever you are hearing. 73. In order to improve your speaking, you should ____________. A. practice speaking more and only talking with your classmates in class. B. make friends with foreigners to talk with them. C. practice speaking with your English teachers and students. D. remember the saying “practice makes perfect”. 阅读第1题 答案:
