Question

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

Answer 1

B

試題分析：考查不定式的否定式和被動語態(tài)。固定搭配tell sb to do sth告訴某人做某事；否定式是tell sb not to do sth告訴某人不要做某事；本句是其被動語態(tài)的形式：be told not to do sth被告知不要做某事；句意：游客們被告知為了保護眼睛不受傷害，不能摘下墨鏡。故B正確。
點評：不定式的否定式就是在不定式符號前面直接加not。所有的非謂語動詞的否定式都是在前面直接加not，這一點要牢記。
