答案
A |
解析
试题分析:考查状语从句的省略句:当主从句的主语一致的情况,可以省略从句的主语和be动词,when offered="when" one is offered。句意:当被提供帮助的时候,人们应该说“Thank you”或“It’s very kind of you.”选A。 点评:如果主句的主语和从句的主语一致,且状语从句的谓语动词中有 be 动词,从句的主语连同be 可一起省略,该类状语从句多为时间、地点、条件、方式或让步等,连词为when, while, though, if, unless, although, as if 等,后面通常接分词、不定式、形容词、名词等。 |
