Computers are very important to modern life. Many people think that in the future we will use computers in everyday life. It is thought that we won’t have to go shopping because we will be able to get most things which are sold in shops on the Internet. There will be no more books because we will be able to get all texts from computers. People will use the Internet to play games, see films and buy food. Also,we can use the Internet to make telephone calls.

Some people are glad about these new ways of shopping and communication (交際). Others do not think that computers will replace our old ways.

Let’s look at books, for example. Some people think that one day we will not read books made of paper. Instead, we will buy and read books using computers. We’ll read texts on small pocket computers. The computers will keep many different books in them at the same time. We won’t need to turn to lots of pages and we will save lots of paper. We will use more and more computerized (計算機(jī)化的) books

Is Internet shopping such a pleasure(愉快的事) as going to the shop? Many people say it is not. It is a pleasure to go into shops and look at things you want to buy. It is also unlikely (不大可能) that many people will want to read large texts on our computers, because paper books may be more friendly. Maybe computers won’t change these two habits .

All living things on the earth need other living things to live. Nothing lives alone. Most animals must live in a group, and even a plant grows close together with others of the same kind. Sometimes one living thing kills another, one eats and the other is eaten. Each kind of life eats another kind of life in order to live, and together they form a food chain(食物鏈).Some food chains are simple, while others are not. But all food chains begin with the sun, and all food chains become broken up if one of the links disappears.

All life needs sunlight to live on. But only plants can use sunlight directly. Plants are“factories”.They make food from sunlight, water and things in the soil and air.

    Plants feed all other living things. Animals can only use the sun’s energy after it has been changed into food by plants. Some animals feed directly on plants, others eat smaller animals. Meat-eating animals are only eating plants indirectly.

    What about human beings? We are members of many food chains. We eat wheat, rice, vegetables, fruits and so on. We also eat meat and drink milk. But men often break up the food chains. They kill wild animals. They also make rivers, lakes and seas dirty. When these rivers, lakes and seas are polluted, the fish in them cannot be eaten. If men eat the fish, they will get strange diseases.

    Each form of life is linked to all others. Breaking the links puts all life in danger.
