Almost all doctors agree that we can improve and maintain good eyesight by eating lots of fresh fruits and vegetables. It is especially important for us to eat vegetables like carrots and sweet potatoes.  Besides, we need to protect our eyes when we spend a long time in bright sunlight. The best way to do. this is by wearing sunglasses that have 100% UV (紫外线)  protection.

Water is the most important in our lives. Not Many people understand this but it’s quite true. The human body can go without food for a long time. We’ve got many examples for this. Yet two or three days without water can usually make people die. Man can’t live without water.

  Many people don’t understand how much water the human body needs to work well, and many people, especially young people, do not drink enough water, even in very hot weather. About two thirds of our body is water. When we do sports, some of the water will get away from our body. If we don’t drink some water, our body won’t have enough water. And if we don’t have enough water, we’ll feel tired and many of us will get ill. So you know how important water is to us.

 But at present we face water crisis(危机). Water is becoming less and less. So， we should protect water resources(资源) and try our best to save water in our daily life. Here are some tips for saving water:

1. Turn off the tap(水龙头) in lime.

2. Take shorter showers.

3. Don’t let water run while washing your face and reuse the water after we finish washing.

4. Encourage your friends and neighbors to join in the action of saving water.

1.Nobody can live without water.

2.About one third of our body is water

3.If one doesn't have enough water, he’ll feel tired and may get ill.

 Today we can see that many people are cutting down the trees in the forests. A lot of        lands have become deserts. If we read newspapers, we’ll learn that the forests on the earth are getting smaller       . We are cutting down large numbers of trees        we need wood and farmland. Some scientists say that there will not be any great forests        20 or 30 years.

What will happen if the forests disappear? A lot of plants will die and the animals will      

their homes. In many places the new farmland will soon look        the old desert. Crops will not grow there. There won’t be enough       , and the weather will get hot and dry. If the climate of the earth changes, life will be        for everyone. Our living environment will become       . More and more rich farmland will disappear. We will suffer a lot from both droughts (干旱) and floods.

It’s our duty        the forests well. Everyone should try his best to make a contribution (贡献) to taking care of the forests. Stop cutting down the trees and make the world greener!
