Question

A. unlessB. whenC. whileD. though

Answer

B

【解析】

试题分析：考查连词。A. unless除非；B. when如果，当……时候，既然；C. while在……期间；D. though尽管。句意：如果她生活在真相里，我如何向她撒谎？无论是在音乐还是人方面。故选B。

【知识拓展】

while,when,as的用法区别

都译为“当…的时候”,区别为：when后的从句谓语动词既可是延续性动词,也可是短暂性动词,而且还可作并列连词,译为“这时”.但以下句型一定用when,作并列连词：

句型A：be about to do…when…正要做…这时(发生另一事)

句型B：was/were doing…when…正在…这时(发生另一事)

句型C：had done…when…刚要做…这时(发生另一事)

1.We were about to set out when it began to rain.我们刚要出发天突然下雨了.

2.He had hardly sat down when his mobile rang.他刚一坐下手机就响了.

3.I was walking along the bank of the river when I fell into it.我正沿河岸散步突然掉进水里.

while后的从句谓语动词只能是延续性动词,强调主从句的两个动词同时发生；while也可作并列连词,表示两个动作的对比,译为“而”“然而”.as则表示两个变化中的动作的同时性,译为“一边…一边…”.

1.While his mother was cooking in the kitchen,the boy fell asleep in the chair.(在一个延续动作过程中发生另一个动作)

2.He hurried home,looking behind as he went.他匆匆回家,边走边往后看.

考点：考查连词
