Question

【题目】— ________ is very important for us ________.

— You are right.

A.This; keep healthB.It; to keep healthyC.That; stay healthD.It; keeping healthy

Answer 1

【答案】B

【解析】

句意：——保持健康对我们很重要。——你说得对。

考查it的固定句型和动词短语。句型“It is+形容词+for sb. to do sth.”：做某事对于某人来说是什么样子的，句中的不定式是真正的主语，it为形式主语。短语keep/stay healthy：保持身体健康。故选B。
