Istudiedinthesameschoolashedid.和Istudiedinthesameschoolthathestudiedin.是否都对明明是同一所学校,为何第一句要用as是因为所接的从句是省略句的缘故吗,第一句的先行词也是学校吗

Question

I studied in the same school _as_ he did.和I studied in the same school that he studied in.是否都对
明明是同一所学校,为何第一句要用as 是因为所接的从句是省略句的缘故吗,第一句的先行词也是学校吗

Answer 1

你好.这两句都是对的.
第一句是方法状语从句.as的定义是：像 -- - -,如同 - - -- ,因此,he后面的其它成分可以省略,只需要加一个did..这一句没有先行词,只有连接词.如果你能看懂：He usually gets up earlier than I do 中的do," I studied in the same school _as_ he did."中的did就不难理解了.
而第二句是定语从句,所以that的后面必须写上完整的句子.
