Never try to work when you are very hungry. If you want to do your homework right after school, you may want to eat something before getting to work. ①Always do your homework before you get too tired. Don't wait until very late in the evening, or your homework will seem much harder than it really is.
   If you have more than an hour's work，you should give yourself a break after an hour. On the other hand，② you should work at least half an hour a time without stopping.
   Don't put it off（推迟）until the last minute. If you put off doing your homework，you will have it on your mind，and you won't enjoy your free time so much. If you put it off until the end of the week or until night before a test，you will have too much catching up to do. A little each night, enough to keep up with（跟上）what is happening each day in school，will take the fear out of tests and keep you on top of it.
   Do your homework at the same time every day. This will help you make it a habit. It will make part of your daily work easier to do，and it will make your free time more enjoyable as well.

   There are many advantages of becoming a professional musician. The biggest advantage is being able to do something you love. You will have the chance to travel to many different places and meet a lot of different people. That will open up your eyes.
   However, there are also disadvantages of being a professional musician. One of the biggest disadvantages for most musicians is that they don't always have enough money. Most of the time, you will be looking for jobs. Sometimes you won't be able to find a good job. Another disadvantage is the place you live in. If you want to be a musician, you usually have to move to an area that has a lot of jobs, such as New York City. The cost of living in these areas is usually very high. The third disadvantage is that you can't have a stable (不稳定的) family life. Different jobs will take a musician to different places, so most musicians are unable to have a regular (正常的) family.

Many of the great men in the world got surprising memories.
   A good memory is a great help in learning languages. Everybody learns his mother language when he is a small child. He hears the sounds, remembers them and then he learns to speak. Some children are living with their parents in foreign countries. They can learn two languages as easily as one because they hear，remember and speak two languages every day. In school it is not so easy to learn a foreign language because the pupils have so little time for it, and they are busy with other subjects, too.
   But your memory will become better and better when you do more and more exercises.
