问题补充：
Tigers are strong and dangerous animals. But now they are in danger.
In the past, there were eight kinds of tigers in the world. But during the 20th century, only five were left. The number of Siberian tigers (东北虎) was about 300, but now it is less than 22. They’re in danger of dying out. If the government does nothing, we won’t be able to see them in ten to twenty years.
In order to stop people from hunting and killing wild tigers, and in order to make wild tigers more, the World Wildlife Fund (世界自然基金会) has started a program (项目) recently (最近). China and twelve other countries joined it.
However, it’s not enough. Remember that nature is a food chain (链). If we hurt and kill too many wild deer and pigs, wild tigers will die out because of hunger (饥饿). So the most important thing is to save the animals that tigers eat. In order to protect the wild tigers, we need call on (号召) more people to stop eating, hunting and killing wild animals.

答案：
(答案→)A
解析：老虎是强大而危险的动物，但现在它们正处于危险之中。他们面临灭绝的危险。记住,自然界是食物链。如果我们伤害和杀死太多野生鹿、猪，野生老虎会因为饥饿消亡。所以最重要的是拯救老虎赖以为食的动物。为了保护野生老虎,我们需要停止进食,狩猎和杀害野生动物。
【小题1】细节理解题。 由“In the past, there were eight kinds of tigers in the world. But during the 20th century, only five were left. （在过去,世界上有八种老虎。但是在20世纪,只剩下五种。）”原来有8种，现在只剩5种了，所以有三种灭绝了，故选A。
【小题2】细节理解题。由“The number of Siberian tigers (东北虎) was about 300, but now it is less than 22.（以前西伯利亚虎的数量(东北虎)约为300,但现在还不到22只。）”由此可推算出，有93%的东北虎死去了。故选C。
【小题3】细节理解题。由“Remember that nature is a food chain . If we hurt and kill too many wild deer and pigs, wild tigers will die out because of hunger .(记住,自然界是食物链。如果我们伤害和杀死太多野生鹿、猪，野生老虎会因为饥饿消亡。)”老虎以食物链中的猪和鹿为食，没有足够的猪和鹿，就会危及老虎的生存，故选D。
【小题4】细节理解题。由“the World Wildlife Fund (世界自然基金会) has started a program (项目) recently (最近). China and twelve other countries joined it.”可知，是中国和12个其他国家参与了世界自然基金会组织的某个项目，而不是只有12个国家加入世界自然基金会，故选B。
【小题5】主题归纳题。根据文章的介绍可知，作者主要描述了老虎的处境和人们如何采取措施保护老虎，所以选 A（最佳题目是：为何和如何保护老虎）。
