It is said that the eyes are the windows of our soul. Beautiful and bright eyes not only show a good health but also make you look very attractive. However, to have healthy eyes you have to look after them properly. Your eyes need everyday attention.
Pay more attention to your diet. First, eat food that is good for your eyes. They are fresh fruits and vegetables as fish, eggs, and milk. Besides, a regular amount of vitamins A and B2 should also be taken.
A regular and sound sleep is a must. It relaxes the eye muscles（肌肉）and gives them the rest required. Sleep not only helps the body to repair its tired tissues (组织). Usually, you must sleep for at least seven to eight hours every day. Loss of sleep can give you dark circles under the eye.
You must exercise your eyes every day. Blink (眨眼) yours eyes at regular periods, which makes the eyeballs watery, and gives them a good wash.
We use our eyes in many unnoticeable and wrong ways. Fox example, if a small thing goes into our eye we start rubbing it, which is wrong. Rubbing can cause damage（伤害） to your eyes. Don’t read or write in poor or bright sunlight. Always use sunglasses as sunlight can cause eye tiredness. Light should not shine directly in your eyes. Too much reading, writing, watching television or working on the computer can also cause eye tiredness.
Remember to always take care of God’s most beautiful gift to you. Your life will be very colorless without your eyes.

    Plants are very important. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals can get their food by eating plants and other animals. Man gets his food by eating plants and animals, too. So animals and man need plants to live. This is why there are so many plants around us.
There are two kinds of plants: flowering plants and non-flowering(无花) plants. Almost all the trees around us are flowers and fruit. Non-flowering plants don’t grow flowers. You can’t see many non-flowering plants around you.

Once upon a time there lived a poor farmer called Smith. He didn't like to share things with others. Smith had a friend who was famous for the wonderful apples he grew.
One day, his friend gave Smith a young apple tree and told him to take it home and planted. The farmer was pleased with the gift, but when he got home, he did not know where to plant
He thought and thought. Finally at night he planted the tree in his wood where no one could see it. But without sunlight and good soil, the tree soon died.
Later the friend asked the farmer why he had planted the tree in such a poor place.
"What's the difference?" the farmer said angrily. "If I had planted it near the road, strangers would have stolen the fruit. If I had planted it in one of my fields, my neighbors would have come at night and stolen some of the apples. If I had planted it near my house, my own children would have taken the fruit,"
"Yes," said the friend, "but at least someone could have enjoyed the fruit. Now you not only have got nothing, but also you have destroyed a good apple tree."
【小题1】Was Smith happy about the gift?
【小题2】When did he plant the apple tree?
【小题3】Where did Smith plant the apple tree in the end?
【小题4】Why did the apple tree soon die?
【小题5】What would probably happen if the farmer had planted the tree near his house?

   Why do they want to do this? The sun’s rays could be   3.   in many ways. They could light up   4.   by night. The warm rays could stop frosts(霜冻) which might come at night and hurt fruit and crops. They could melt（融化) 5. icebergs in the ocean.

 What do you think of a forest, what do you see? Just trees? Or do you see many other things, such as singing birds, colorful plants and wild flowers?

  The forest is a whole of its own. It is full of many different living things. But even though they are all different, they have one thing in common: they all need each other in order to live on.

  The trees feed the forest "people" by making food in their leaves; by using sunlight to join water and minerals from the soil and air. Their deep network of roots joins the soil together and stops it from dying out, making it possible for living things to live in it.

  Human beings are like the living things in the forest. We need one another in order to live. We need the farmers to grow our food, railroad and truck drivers to bring it to our shops and clerks (售员)to sell it to us. We need people to prepare our food and cook it and others to take our waste things away. Then, of course, we need doctors, nurses, government leaders, mailmen, telephone operators, and many others.

  We also need other human beings in another way. We need people for friendship, to talk over our problems, exchange ideas. Think how lonely and unhappy you would be if you lived all alone.

  Life is a matter of giving and taking. We need to help other people as much as we need other people to help us. Think what a good feeling you have when you have done something for someone else. You know, being a volunteer is so great!
