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
| B |
| 试题分析：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。 |
