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.
