Question

We advise parents _____ their children at home alone in order to keep them away from danger.

A.not leave      B.not to leave

C.leave      D.to leave

Answer

B

【解析】

试题分析：句意：为了使孩子远离危险，我们建议父母不要单独把孩子留在家里。advise sb to do sth,建议某人做某事，动词不定式的否定形式就是在to前面加not，故advise sb not to do sth,建议某人不要做某事。结合句意，故选B。

【考点定位】考查动词不定式的否定形式。
