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.

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.

Dear Sandy,

     How are you? It's Saturday today and I have some time to write to you. We're busy from Monday to Friday. We get up at six thirty in the morning. After some exercise we have breakfast. We have five classes a day and the first class starts at eight. Our teachers are strict. They often ask us a lot of questions and some of them are very difficult.

     We do sports at five in the afternoon. We play basketball, soccer, volleyball, baseball, tennis or pingpong. Some of my classmates like art. They can sing or dance or draw. Sometimes Miss White, our biology teacher, takes us to the zoo(动物园).

     After supper we can watch TV. But we do our homework first. I like math and often do some difficult exercises(练习). So I go to bed at ten thirty. I'm often tired but I like them.

     Please write to me and tell me about yourself.

                                                             Yours, 

Zhou Hong
