We sometimes call the lion “the king of the jungle (丛林)” because it is stronger and more dangerous than other animals. It can run faster than many animals and it can hunt (捕猎) the best. It is the highest animal in the   21  food chain (食物链).[
In the sea, the shark is one of the animals at the  22  of the food chain. It can swim faster than most other sea animals, and it can use its big teeth to eat them.
What is at the top of the world’s food chain?  23  are! We are not the biggest or fastest, but we are the   24  We could not run faster than cheetahs (猎豹),  so we  25  cars and now we can move the fastest. We could not  26  better than lions, so we invented guns (枪). Now we can hunt the best.
People’s inventions are clever, but they can be dangerous, too. For example, people invented  27 , and now they make the air and rivers dirty. This can make   28  changes. Dirty rivers kill fish.  Then bears cannot eat the fish and the bears die. If we kill one part of the food chain,   29  also die. Remember that we are a part of the food chain, so we are in danger too! If we protect animals, we are protecting   30 ! We should and we could do something for the world!

Every year landslides cause 25 to 50 deaths and $2 billion in damage in the United States. And in December, a single event killed more than 2000 people in the Philippines. Sending workers to stabilize mountainsides using steel bars can help a lot, but it introduces new difficulties because of dust and loosen heavy, dangerous debris from the work. “It’s a quite dangerous job,” says Giorgio Pezzuto of D’ Appolonia, working with eight other companies. Now there may be an answer: a three-ton robot called Roboclimber.
“The idea is to operate a machine far away that can do the stabilizing job without a human being near,”says Pezzuto, manager for the project, which is supported by a European organization. Engineers say that the machine will be faster and cheaper than manual labor. The robot, a large radio-controlled four-legged spider, has cost at least $2 million so far. It should be able to climb mountainsides, drill holes and insert steel bars there. Testing should begin in May.

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 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. 

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.

2.Which living things can use the sun’s energy directly?

A. Animals       B. Plants         C. All living things

3.Who often break up the food chains?

A. Human beings

B. Animals

C. Plant and animals

4. Which of the following do you think is the best title of this passage?

A. Animals         B. Plants       C. Food Chains    

5.Where can you probably find this passage?

A. In a news report.

B. In your textbook.

C. In a business magazine.
