Do you like to sit in front of the computer and play computer games hour after hour? Have you ever thought of what that may be doing to your health? More and more children are becoming overweight(肥胖的) and growing less creative because they spend too much time in front of the computer according to a survey.

    Last week Child Protective Services(兒童保護組織)in America organized an activity. The aim of the activity was to encourage children to do some outdoor activities instead of playing computer games at home. Many American children spend about 1,000 hours a year playing computer games — more time than they spend in school. As a result, they are overweight. Some of them have very poor eyesight, and they can’t see clearly.

   Everyone should pay attention to his health and try to keep healthy. The doctor says that the longer children play computer games, the more overweight they may become. And the junk food children eat while they’re playing computer games makes the weight problem more serious.

   To keep fit, children need to take exercise regularly, play outside with friends, and explore the world around them. Can you spend two weeks without playing computer games? It might be difficult for computer lovers, but why not have a try?

【小題1】Children may become______ if they play computer games all day.

Have you ever seen a horse with toes(腳趾)？Millions of years ago, horses had many toes. They had four toes on each front foot. They had three toes on each back foot. The horses were no bigger than the cats.These small horses lived in the forest. The toes helped the horses run on the soft, wet ground.
At first, it was very hot in the forest. But the weather changed. It became very cold. Many trees could not live in cold weather. The trees died and fell. Open fields took the place of forests. The sun made the ground dry and hard.
Horsed began to change, too. They began to get bigger. This took a long time. On the dry, hard land, horses needed only their middle toes for running. Their middle toes became hard. After a long time, horses had only one hard toe on each foot. Now we call this hard toe a hoof.
【小題1】How many toes did a horse have millions of years ago?
