【简答题】
How to pass an exam? Everyone wants to know the answer. A good way is to work hard every day. You may fail in an exam if you are lazy for most of the time and only work hard for a few days before the exam. Many students do not know how to learn English well. Some study very hard, but still cannot get a good result. What should you do? Do not just remember words when you are learning English. Try to read stories in English. Speak English as much as you can. Tell stories to your friends in English. A few days before the exam you should relax and go to bed early. Do not study very late at night. Before you start the exam, you should read carefully over the paper. Try to understand the real meaning of each question before you write down the answer. When you finish your exam, you should read your answers again, correct the mistakes and make sure you have not miss anything out.
