A

     A good way to pass an exam is to work hard every day in a year. You may fail in an exam if you are lazy for most of the year and then work hard only a few days before the exam. If you want to be good at English, you have to read stories in English. And speak English as much as possible. A few days before the exam you should go to bed early. Do not go to bed late at night studying. Before you start the exam, read carefully over the question paper, try to understand the exact （确切) meaning of each question. When you have at last finished your exam, read over your answers. Correct (改正) the mistakes if there are any and be sure that you have not missed anything out.
