問題詳情：

—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：——今天太熱了。為什麼不在河裡游泳呢？——不，我們不能在河裡游泳。我們的老師和父母總是*告我們不要在河裡游泳。這太危險了。

考查動詞不定式的否定形式。*告某人不要做某事warn sb. not to do sth或warn sb. against doing sth，結合選項，可知用warn us not to swim in the river “*告我們不要在河裡游泳”，故選C。
