He tried to learn English well ,______ did his classmates.
A. as B.which C. that D . and
答案是A 。 as在这儿引导的是什么句子？as在这儿应该是“就像”的意思。但是在引导倒装句是“虽然
’，在这儿说不通啊。请帮忙讲解一下。急用。谢谢。

该句as 引导的不是让步状语从句，所以在这里无“虽然”的意思。as的倒装句表示让步的具体语序为：形容词/副词/分词/名词短语+as+主语+谓语动词，如：　
Young as he is, he is knowledgeable.

这里as引导的倒装句的意思确实是“就像，正如，和一样”的意思。例：
His eyesight failed, his wife and son died, as did his contemporaries.
他的视力衰退了，妻子和儿子去世了，和他同时代的人也都逝去。

He believed, as did his family, that you were telling the truth.
他和他全家人一样，相信你说的是实话。
