问题 选择题

Tourists were told _____their sunglass to protect their eyes from the strong sunlight

A.to not take off

B.not to take off

C.not taking off

D.not take off

答案

答案:B

题目分析:考查不定式的否定式和被动语态。固定搭配tell sb to do sth告诉某人做某事;否定式是tell sb not to do sth告诉某人不要做某事;本句是其被动语态的形式:be told not to do sth被告知不要做某事;句意:游客们被告知为了保护眼睛不受伤害,不能摘下墨镜。故B正确。

点评:不定式的否定式就是在不定式符号前面直接加not。所有的非谓语动词的否定式都是在前面直接加not,这一点要牢记。
