Question

【题目】Teachers often tell us_ _______in the river after school.

A. don't swim B. not swim

C. not to swim D. to not swim

Answer 1

【答案】C

【解析】试题分析：句意：老师们经常告诉我们放学后不要去河里游泳。don’t swim不要游泳，是谓语动词形式；not swim是不带to的不定式的否定形式；not to swim是动词不定式的否定形式；to not swim形式错误。这句话的谓语动词是tell，常用于句型tell sb. to do sth.，否定形式在动词不定式前加not。故选C。
