Question

【题目】—If we don’t protect the environment, plants and animals will die out on Earth one day.

—So everyone should try his best to do something for the environment.

A.appearB.disappearC.happen

Answer 1

【答案】B

【解析】

句意：——如果我们不保护环境，地球上的动植物总有一天会灭绝。——所以每个人都应该尽自己最大的努力为环境做点什么。

考查动词。A. appear出现；B. disappear消失；C. happen发生；根据原句是灭绝，也就是消失不见了，所以用disappear消失，故选B。
