—It is so hot today. Why not swim in the river?

—No, we can't swim in the river. Our teachers and parents always warn us ________in the river. It's too dangerous.

A．to not swim            B．swimming              C．not to swim            D．not swimming

【回答】

C

【解析】

句意：——今天太热了。为什么不在河里游泳呢？——不，我们不能在河里游泳。我们的老师和父母总是*告我们不要在河里游泳。这太危险了。

考查动词不定式的否定形式。*告某人不要做某事warn sb. not to do sth或warn sb. against doing sth，结合选项，可知用warn us not to swim in the river “*告我们不要在河里游泳”，故选C。
