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.

Drinking water is good for your health. There are some scientific ways of drinking water.
1. It is the best medicine to drink two glasses of water in the morning.
2. Drink clean water.
3. Drink the water that has not been boiled.
Many people think boiled water is safe and good to people’s health. In fact, it is not true. The boiling point of water is 100℃. By boiling it, most bacteria（细菌）in water can be killed. In the past, the water was less polluted. So boiling was a good way to make clean water. But heavy metals and other dangerous things in today’s water are much more terrible than bacteria. Boiling doesn’t fix that problem. And boiling water may give us more of the dangerous things in our glass.
4. Never use soft drinks to take the place of water.
5. Water is also needed in winter.
6. Drink water at the right time.
1) After getting up in the morning, you have less water in your body, because you weren’t drinking for the whole night. So you should drink some water to keep your health after getting up in the morning. That can prevent high blood pressure, cerebral hemorrhages（脑溢血）and so on.
2) Drinking water at about 10 am helps your body keep enough water.
3) Drinking water at about 3 pm can clean out the wastes in your body.
4) About eight o’clock in the evening is the best time to drink water. Your blood gets thicker when you sleep. Water will make your blood less thick.
Besides, we should drink 2L of water every day. Water is so important for our life. We should drink water often.
