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 (食物链). 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 (联系) disappears.
All life needs sunlight to live on. But only plants can use sunlight directly (直接). Plants are “factories”. They make food from sunlight, water and things in the soil (土壤) and air.
Plants feed all other living things. Animals can only use the sun's energy (能量) 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 (小麦), rice, vegetables, fruits and so on. We also eat meat and drink milk. But humans 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 (疾病).
Each form of life is linked to all others. Breaking the links puts all life in danger.

Topic: How can we help to protect the environment? |
Time: 8:00 am—9:30 am, tomorrow, December 22 |
Place: In the school hall |
Attention: Be on time |
Content: Our planet is in trouble! Almost every day we seem to hear about problems of the environment——pollution, acid rain, climate change, the destruction of rainforests, and more and more animals and plants are disappearing. Nowadays, most of us know that humans have caused a lot of these problems. We are very worried about the future of our earth. We must find ways to solve these problems, or the earth will no longer support human life. Each of us, whatever age we are, can do something to protect the environment. We are all responsible (有责任的) for the environment. What can we do? Come and listen to Mr. Green's lecture tomorrow. The Students' Union |
Our life will be different from nowadays with robots appearing in our homes. So what will the future be like? Here are some students' ideas.
|
I expect to live in a more beautiful and cleaner city. The street will be cleaned by the robots once a day. —Ben |
|
There will be more kinds of food to choose from and the food will be more delicious. The robots can make food for us。 —Karen |
|
We do not have to spend much time on heavy work because robots will take up most of our work, such as washing the clothes. So we will have more vacations. We can take a vacation on the moon. We will not live on the earth but on the moon or other planets. —Mark |
|
I expect that most families will have their own planes made by their robots, and travel will become more convenient. The plane is faster than any other transportation(交通工具). —Sue |
|
I hope robots can make clothes for us. The clothes could change their sizes and colors by themselves. —Sam |
