He has two sons,both of whom work as chemists.这里的as做什么成分?

问题描述:

He has two sons,both of whom work as chemists.
这里的as做什么成分?

只不过是个介词,不单独做句子成分。

as本身有 作为 的意思
work as以。。。为职业

as 在此作方式状语。both of 之后whom引出从句修饰SONS, as在从句中充当方式状语。

as本身有 作为 的意思
例 As a teacher,he teaches every students well.
另外 work as 有 职业是 的意思

work as以.为职业
