They will telephone the police and complain about it the noise .A.if; stops | B.unless; stops | C.if not; stops | D.unless; doesn’t stop |

答案
B |
解析
试题分析:根据题干,本句的意思是“如果噪音不停止,他们就打电话报警抱怨。”如果用if的话,应该用if the noise doesn’t stop,故AC排除;unless是“除非”的意思,等于if……not,其后面的句子不能再用否定形式。所以本题选B。 点评:要完成本题需要对unless的用法熟练掌握,unless等于if……not;条件状语从句的用法是:如果主句用将来时,则从句应该用一般现在时。 |
