Animals have been killed for their fur and feathers, for food， for sport， and simply because they were in the way。

Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds
in the United States alone are considered in danger。

Why should people care？ Because we need animals。

And because once they are gone, there will never be any more。

Animals are more than beautiful or interesting or a source of food. Every animal has its place in the balance of nature。

Destroying one kind of animal can create many problems.
For example, when farmers killed large numbers of hawks(鹰)， the farmers’ stores of corn and grain were destroyed by mice。

Why? Because hawks eat mice。

With no hawks to keep down their numbers, the mice multiplied quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem。

And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws。

These laws forbid the killing of any animal or plant on the danger list。

Slowly, the number of some animals in danger is growing.
1. What is the best title for the passage?
A. Save the animals
B. Useful animals
C. Laws for animals
D. Animals in danger
2。

Animals are important to us mainly because _______.
A. they give us a source of food
B。

they are beautiful and lovely
C. they keep the balance of nature
D。

they give us a lot of pleasure
3。

Which of the following is NOT true?
A。

People care much about animals because they need them.
B. People must not kill any animal or plant.
C。

Killing all mice may cause some new problems。

D。

Once a certain kind of animal is gone forever， there will never be any more. 4。

We can infer from the passage that _______。

A。

people have known the importance of animal protection for a long time
B. animals play an important role in people’s life
C. the number of hawks is on the decrease
D。

many countries passed laws forbidding the killing of any animal
18、 Many animal and plant species have become extinct and many more are in critical danger。

Dodos
The flightless dodo was native to the Island of Mauritius in the Indian Ocean. It lived off fruit fallen from the islands trees and lived unthreatened until humans arrived in 1505。

The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the island by humans such as pigs, monkeys and rats. The population of dodos rapidly decreased and the last one was killed in 1681。

Rhinos
The rhino horn is a highly priced item for Asian medicine。

This has led to the animal being hunted in its natural habitat。

Their number has rapidly decreased in the last 50 years， and the animals remain under constant threat from poachers(偷猎者)。

The giant panda
The future of the World Wildlife Fund's symbol is far from certain. As few as 1,000 remain in the wild。

The Chinese government has set up 33 panda reserves to protect these beautiful animals and made hunting them punishable with 20 years in prison.
Whales
The International Whaling Commission is fighting to ensure the survival of the whale species。

Despite the fact that one-third the world's oceans have been declared whale sanctuaries(保护区）, 7 out of 13 whale species remain endangered.
Tigers
The last 100 years has seen a 95％ reduction in the number of remaining tigers to between 5,000 and 7,000 and the Bali, Javan， and Caspian tigers are already extinct. The South China tiger is close to disappearing， with only 20 to 30 still alive. Like the rhino horn, tigers' bones and organs are sought after for traditional Chinese medicines。

These items are traded illegally along with tiger skins。

答案:1—4 ACBB
解析：1。

标题归纳题.文章提到动物面临的生存现状、保护动物的必要性以及目前一些国家对
濒危动物采取的保护性措施等方面都体现了保护动物的主题，故文章标题应是"保护动物”.
2。

细节理解题。

根据第四段中”Animals are more than.。

. in the balance of nature。

"
可以看出，每一种动物的存在都是有道理的，都是为了维持自然界的平衡.
3。

细节理解题。

根据第三段中的”Because we need animals。

”可确定A项正确。

根据第四
段中的"Every animal has its place in the balance of nature。

"可确定C项正确；根据第
一段中的"Thousands of kinds of animals have disappeared from the earth forever."可
确定D项正确。

B项说法过于绝对，由文章最后一段中"These laws forbid the killing of any animal or plant on the danger list."可知人们可以捕杀动物，但要有一定的限度.
4.推理判断题。

根据第一段和第四段的描述可以看出，此前人们对于动物的保护并不关注，当
然也并未意识到动物保护的重要性，故A项错误。

通过对文章第四段的理解可以得知动物在人
们的生活中起着重要作用,故B项正确. 文中提到鹰的数量由于人类的捕杀而减少，但并非现在
的情况，故可排除C项。

D项中提到许多国家制定了法律来禁止对一切动物的捕杀，忽略了文中
on the danger list这个说法，故该项是不对的。

18答案及解析：
答案：1—3 DCD
解析:1.细节理解题。

根据文章第二段的”The population of dodos rapidly decreased and the last one was killed in 1681."一句可判断渡渡鸟是灭绝的动物之一，再根据最后一段中的"。

.。

the Bali， Javan, and Caspian tigers are already extinct。

"一句可得出答案。

2。

细节理解题.文章的第三段和最后一段提到"犀牛角和老虎的骨头及器官"有很高的药用价值。

3.细节理解题。

从第四段中的”The future of the World Wildlife Fund’s symbol is far from certain.”—句可得出”世界自然基金会"的标志是"大熊猫”，而不是"鲸"。
