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.?

Blogs (博客) are the place where young people go to reveal(釋放) their souls（靈魂）. Many people enjoy the freedom in blogging. Some, however, find that putting one’s life online can have a price. Some students in America got suspensions (暫停) because on their blogs they posted threatening words to their teachers.

Recent surveys found that nearly one fifth of teens who have access to the Web have their own blogs. And 38% of teens say they read other people’s blogs. By comparison, about a tenth of adults have their own blogs and a quarter say they read other people’s online journals.

With the development of the Internet, more and more people will be engaged in blogging.

In another survey, 79% of teens agreed that people at their age aren’t careful enough when giving out information about themselves online. Besides, careless blogging can also affect blog viewers. When you are angry or frustrated, your blog is the first place you turn to. The words you post then may not be rational which you may regret(后悔) later. To reduce the negative effect, change the permission setting and make such posts “private” so that only you can read them.

As long as you are careful with what you post, blogging is a great means of staying in touch with friends and displaying one’s creative works.
