David is such a good boy that ___ all the teachers like him A.that B.who C.as D.whom
问题描述：
David is such a good boy that ___ all the teachers like him A.that B.who C.as D.whom
答
选A……
因为such……that……固定句式搭配，引导结果状语从句，之所以不选as，是因为后面从句中like已经有了宾语him，不需要as再去充当宾语，选that是因为that不充当后面从句中的任何成分，只起引导作用。
希望能帮助到你。
答
David is such a good boy that all the teachers like him.不填
such ...that ...
David是如此的出色（好男孩）以至于所有的老师都喜欢他。
答
这道题啥都不填，已经完整了.若为
David is such a good boy ___ all the teachers like 则选择as
答
B
答
选C
因为从后面的all the teachers like him,可以看出,这是个完整的句子,不是定语从句,而是一个原因状语从句,所以选择C,表示原因.
