【简答题】
Read a lot, I mean a lot! You have to increase your ability for reading. Many students are in the habit of reading only when their exams are approaching while some others read only what they are taught or things that must be read because it is in their curriculum. But listen to me now, I am telling you from my own experience that it is a very bad habit and it is not enough to improve your intelligence. You have to learn and get ready to become versatile in your reading. The fact that you are studying medicine in school does not mean that you should not know one or two things on politics. Many people have complained to me that they find it hard to read stuffs like novels but I just shake my head in pity for them because it is obvious they have failed to realize the truth in that wise saying by Margaret Fuller that “today a READER, tomorrow a LEADER!” When you read, you get to “see” so many places and it will be as if you have visited those places in real life. This is because reading will improve your imagination and creativity and understanding. You also get experience from learning about how people dealt with their various problems thereby saving you from going through the pains and difficulties they must have gone through! Reading will also help you in improving your vocabulary because you will certainly start coming across so many new words which you will try as much as possible to get accustomed to with the help of the dictionary! The good thing about increasing your vocabulary is that it will also improve your thinking ability. After all, we think in words and the more words you know, the easier it will become for you to express yourself or your thoughts. And when you read, make sure you read so wide because the more you read, the more you know and the more you know the more intelligent you can become. 小题1:According to the author, what should students do in terms of reading? A.They needn’t read unless the exams come. B.They should read books about intelligence. C.They must read about politics when their major is medicine. D.They should read as wide as possible. 小题2:The underlined word “versatile” in Paragraph 2 is closest in meaning to _____. A.interested B.many-sided C.content D.confident 小题3:What is the best title for the passage? A.Increase your ability for reading B.Read wide and improve your vocabulary C.Reading improves your intelligence D.Reading makes you a leader tomorrow 小题4:What is the benefit of knowing more words? A.You will get used to referring to the dictionary when meeting with new words. B.You will have less difficulty expressing your opinions. C.Vocabulary will improve your creativity. D.You can pass your exams with ease.
