Question

    CHINA has built a biscuit factory to make food for its captive (圈养的) giant pandas, giving them a healthier diet (日常食物) than the usual steamed bread.

The special biscuits, developed by the Chengdu Giant Panda Breeding and Research Centre, are shaped like bamboo so they will not seem unfamiliar to the pandas.

"The cream-colored biscuit, made of bamboo, is rich in vitamins and has 30 per cent more fiber (纤维) than normal bamboo," said Yu Jianqiu, who is in charge of the project.

Steamed bread, which is eaten by most captive giant pandas as well as fresh bamboo, loses much of its goodness when cooked, often causing bad health. What's more, it can only be stored for a short time, making pandas expensive to feed.

Thirty pandas have tried the biscuits since the factory was completed in October.

"They love our new biscuits," Yu said. "In time, all captive pandas will be given the new food."

Around 1,000 giant pandas live in the foggy mountains around the Sichuan basin (盆地) in southwest China, while about 140 live in captivity around the world.

The destruction of forests, a panda's natural home and major food source, is the biggest threat to the animal.

In 1998, China banned the cutting down of trees in panda-inhabited areas to help save an animal seen as a national treasure.

1.Why are captive giant pandas given the special biscuits?

A.Because there is not enough fresh bamboo around.

B.Because they are healthier and easier to store.

C.Because the price of steamed bread is too high.

D.Because pandas like to change their food.

2.How does steamed bread cause panda's bad health?

A.The bad taste makes pandas tired of eating.

B.The bread is not fresh enough to keep pandas healthy.

C.Cooking makes it lose what is important to pandas' health.

D.The steamed bread goes bad easily enough to harm pandas.

3.Which of the following is true according to the passage?

A.There are fewer than 1000 pandas living in the world right now.

B.Most of the pandas in captivity are now living on the newly developed biscuits.

C.The pandas are now in great danger mainly because of trees being cut down in forests.

D.Pandas like to eat food which has enough vitamins and as much fiber as possible.

【解析】

本文是一篇说明文，文章主要讲述中国建立饼干加工厂为熊猫制作一种饼干，这种饼干比之前熊猫吃的馒头和新鲜主子更加健康，更适合熊猫。

1.细节理解题，根据“CHINA has built… a healthier diet than the usual steamed bread.”以及“Steamed bread… making pandas expensive to feed”可知，馒头和新鲜的竹子在烹饪时会失去大部分营养，造成熊猫不健康，储存时间短，价格昂贵，而饼干则会比馒头更加健康，与馒头相反的话，说明也更容易储存。故选B。

2.细节理解题。根据“Steamed bread…often causing bad health.”可知，馒头在烹饪时会失去大部分营养，造成熊猫不健康，所以馒头的烹饪会流失熊猫健康所需的物质。故选C。

3.细节理解题，根据“Around 1,000… around the world.”可知，中国四川有大概1,000只熊猫，在世界其他地方还有140只左右，所以一共有1140只熊猫在世，不会少于1,000只，A错误；根据“Thirty pandas have…given the new food."”可知，已经有三十只熊猫在尝试吃这种饼干，所有的熊猫将会都吃这种饼干，并不是现在已经在吃了，B错误；根据倒数第二段“The destruction of forests…threat to the animal.”可知，森林的毁坏让熊猫的家和食物都受到了严重威胁，C正确；根据第三段“The cream-colored biscuit… than normal bamboo”可知，新饼干比普通竹子含有更多维他命和多30%的纤维，但是没有说纤维越多越好。故选C。
