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. 
【小題1】How does every living thing on the earth live?
A. Each plant can live alone.
B. Each animal can live alone.
C. Every living thing on the earth cannot live without others.

科目:初中英語 來源:2014屆江蘇漣水縣南集中學八年級下學期期末考試英語卷(解析版) 題型:閱讀理解

Animals, including insects, don’t have a ‘language’ like ours. They do not ‘talk’ to each other in words and sentences. But if we watch them, we can see that they do have their ways of communicating (交流) with each other.

Can you see the rabbit’s tail? When rabbits see this white tail moving up and down, they run away. They know that they are in danger. The rabbit has told them something without making a sound. It has given them a signal.

Many other animals use this kind of ‘language’. When a cobra(眼鏡蛇)is angry, it raises its head and makes itself look powerful(有力的). This warns other animals. When a bee(蜜蜂)has found food, it goes back to its home. It cannot ‘tell’ the other bees where the food is by speaking to them, but it does a little dance. This tells the bees where the food is.

Some animals ‘say’ things by making sounds. A dog barks, for example, when a stranger comes near. A cat purrs when it is pleased. Some birds make several different sounds, each with its own meaning. Sometimes we human beings speak in the same way. We make sounds like “Oh” or “Ah” when we are frightened or pleased or when we drop something on our toes.

1.Which one is TRUE according to the passage?

A.Animals have languages like human beings.

B.Bees communicate with each other by dancing.

C.Animals can use words.                                                 D.Animals are brave.

2.A rabbit uses its tail to ___________.

A.warn other rabbits when they are in danger   B.tell other rabbits where food is

C.make itself look powerful                 D.help it to run fast

3.When a cobra is angry, it __________.

A.makes a loud noise                      B.raises its head

C.moves up and down                     D.does a little dance

4.Several different sounds can be made by a __________.

A.rabbit            B.bee              C.bird              D.fish

5.From the passage, we know that ________ use words and sentences to express ideas and thoughts.

A.all living things      B.all animals         C.some birds        D.human beings
