【句型透视】as作为连词的意义及用法主要有:
(1)“如同;按照”,引导方式状语从句;
(2)“当……时候;一边……一边……;随着”,引导时间状语从句;
(3)“因为;既然”,引导原因状语从句;
(4)“尽管”,引导让步状语从句(从句使用部分倒装,即将形容词、副词、名词、动词等放于as前面;单数可数名词提前时应省略冠词);
(5)引导比较状语从句,常用于as ... as ... 句型,意为“像……一样……”(第一个as是副词,第二个as是连词)。
When in Rome, do as Romans do.
入乡随俗。
—Coach, can I continue with the training?
—Sorry, you can't as you haven't recovered from the knee injury.

②They sang songs as they were doing farm work.一边……一边……
