【简答题】
把下面画线部分的句子翻译。 You probably think you will never be a top student. In fact, you can become a better student if you want to. You maybe say, 1'It takes me lots of time to study, but I don't still make progess.' But if you can use your time well, you may improve your study without much work. There are a few ways here to help you with your study. 2 Plan your time carefully . You should make a list of things that you have to do during a week. First, you should write down the time for eating, sleeping, dressing, etc. Then you should use the time that you can study. 3 Of course, studying shouldn't take all of your time. Don't forget to leave enough time for hobbies yourself. Find a good place to study. Keep this place, which may be a desk or just a corner of your room. No games, radio, or television! When you sit down to work, think only about the subject! Make good use of your time in class. 4 Listen to what the teacher says carefully. Careful listening in class means less work later. You also need to take notes in class, because it can make it easier for you to learn well. 5 Can you give any other ways to study? 1._____________________________________________________ 2._____________________________________________________ 3._____________________________________________________ 4._____________________________________________________ 5._____________________________________________________
