阅读表达。

阅读下面的短文,并根据短文后的要求答题(请注意问题后的词数的要求).

     Animals are natural resources that people have wasted all through our history.

     Animals have been killed for their fur and feathers, for food, for sport, simply because they are in the way.(天生就该如此) 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 State alone are considered to be in danger.

     Why should people care? Because we need animals. And because once they are gone, __________________

_____________________________________________. 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 (老鹰), the farmers' stores of corn

and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep

down their numbers, the rats and mice multiplied (繁殖) 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 to protect animals in danger.

     Quite a few counties 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 of this passage?(please answer within 5 words.)

________________________________________________________________________

2.Which sentence in the passage can be replaced by the following one?

   The number of rats and mice increased very fast because there were not enough hawks to kill them.

3. Please fill in the blank in the third paragraph with proper words or phrases to complete the sentence.

    (please answer within 10 words)

4. What is the animals' future in your opinion? And why?(please answer within 30 words.)
