OG10语法268题及GWD22语法总结日记(二)(2)
1. 作“当……的时候“,引导时间状语从句。留意与when、 while的用法区分。（同上）
2. as=since, 作“既然“、“由于“解,引导缘由状语从句,常用来表示已为人们所知或显而易见的缘由或理由。如:
As / Since you”re not feeling well, you may stay at home.
3. as=in the way that, 作“像“、“根据……的方式“解,引导方式状语从句。如:
He speaks English as Americans do.
4. 用于as...as...或not so/ as...as...中,前一个as是副词,后一个as是连词,引导比拟状语从句。如:
I don”t speak English so/ as well as he does.
5. 作“虽然“、“尽管“解,引导让步状语从句。常用倒装语序,即adj. /adv. / n.+ as +主语+谓语+主句。如:
Child as he is, he knows a lot. (child前不用冠词)
二、 as作关系代词,引导定语从句,作“正如“、“这一点“解。如:
He is very careful, as his work shows.
另外,领先行词被the same, such等词修饰时,常用as来引导定语从句。如:


Such a clever boy as he can learn anything quickly.
三、 as作介词的用法:
as引导的介词短语大多用作状语,as译为“作为“;少数状况可引起宾语补足语。如:
As a League member, I”ll take the lead in everything. (状语)
She works as a doctor. (状语)
They have me as one of their own children.(引起宾语补足语)
When后边接名词
