She then has further babies every three to four years. In most cases a single gorilla is born, but she sometimes gives birth to twins. 3 They need about 30 kilograms of vegetation every day to survive. They also eat insects but rarely drink water because there is enough moisture in the plants.

The habitat of mountain gorillas is getting smaller and smaller. Gorillas are also threatened by poachers, who sell their babies to zoos. It is believed that there are only about 600 mountain gorillas left.

Ⅰ. 【语篇解读】本文是一篇说明文。文章呼吁人们帮助拯救鲨鱼，不要为了吃鱼翅而捕杀鲨鱼。
1. especially 考查副词。修饰形容词popular，用副词形式，故填especially。
2. But 考查连词。句意：但你意识到每次享用一碗鱼翅汤时，你就在杀死一整条鲨鱼吗？该句与上文是转折关系，所以用but；句首单词首字母大写，故填But。
3. the 考查冠词。句意：当人们捕捉鲨鱼时，他们割下它们的鳍，然后把鲨鱼扔回海里。
4. harmful 考查形容词。句意：这种方法不仅残忍，而且对环境有害。be harmful to对……有害。
