Do you get enough sleep? With so much homework it's often difficult to get the rest you need. But you need to try, because sleep keeps you healthy and it stops you getting fat.
Recently, a group of US scientists did a study (調(diào)查) of kids aged between 8 and 13. The study found that if kids sleep for just one extra (額外的) hour each day, the chance of their getting fat is cut by about 30 percent .
Why? When people don't get enough sleep, they become tired. When they are tired, they don't exercise enough. Also, kids like snacks: If they are awake (醒著的) an extra hour or two each day,they have more time to eat snacks or other unhealthy foods.
So, how much sleep should you get? Scientists suggest 10 to 11 hours a night for kids aged 5 to 12. For older kids, eight to nine hours will do.

A few years ago, I went to China with my parents. The five-day trip left me with a deep impression.
As the capital of China, Beijing is a very beautiful city with fresh air and clean streets which make the travelers feel very pleased. To my surprise, many people there were learning English. Later I was told that they did so because Beijing would hold the 29th Olympic Games and they wanted most foreigners to understand them. They strictly kept the traffic rules. When there was a red light, no one was seen crossing the street.
Of all the places I visited, I liked the Summer Palace best. To our surprise, although it was winter when we were there, we still saw green trees and many fresh flowers. The whole park was very beautiful.
We visited a very modern football field. We were told the buildings where the Olympic Games would be held were even better than that. I also enjoyed skiing in Xiangshan. Skiing is an interesting and exciting sport liked by many people.
In my eyes, China is a nice place and Chinese people are very kind. In Beijing Station, there were so many people, and most of them were going home to spend the Spring Festival—the most important Chinese festival, with their families. Passengers helped each other carry luggage(行李), and they were very kind to foreigners. We were given a card by the hotel we stayed at, on which was the address of the hotel. With the card we never got lost in the city.
The five days passed quickly, but the trip left me a lot of sweet memories.

If you go into the forest with friends, stay with them. If you don't, you may get lost, this is what you should do. Sit down and stay where you are. Don't try to find your friends-let them find you instead. You can help them find you by staying in one place. There is another way to help your friends or other people to find you. You can shout or whistle (吹口哨) three times. Stop. Then shout or whistle three times again. Any signal (信號(hào)) given three times is a call for help.

give you two shouts or two whistles. When a signal is given twice, it is an answer to a call for help. 
If you don't think that you will get help before night comes, try to make a little house with branches 
(樹枝), make yourself a bed with leaves and grass. 
When you need some water, you have to leave your little branch house to look for it. Don't just walk away. Pick off small branches and drop (扔下) them as you walk in order to go back again easily. When you are lost,the most important thing to do is to stay in one place.

Many students ask for advice about improving (提高) their English. There are three basic(基本的) questions.

The third question is about vocabulary. Oliver, from Anhui wrote, “I want to remember all the new words. I write them down, but I forget them quickly. What should I do?”
Try to remember eight or ten words a day. Write them on pieces of paper and place them in your bedroom. Say the words when you see them, and change them every day. And when you’re shopping, how about counting the English words, or saying the English names for everything you see?
