引导定语从句as与which, that的用法区别
①such…as(引导定语从句),such…that(引导结果状语从句)
“so/such…that….”引导的是结果状语从句,从句的成分是完整的,也就是说that只起连接作用。
“such… as…”引导的是定语从句,从句的成分是不完整的,也就是说as代替先行词在从句中充当成分。比如下列三句表达的是一个意思:This is such a heavy stone as no one can lift. (定语从句)
This is so heavy a stone that no one can lift it. (结果状语从句)
This is such a heavy stone that no one can lift it. (结果状语从句)
②the same…as和the same ...that 的区别
the same…as表示“与……一样(但不是同一个)”,而the same…that表示“同一个,就是那一个”的意思。
The coat you wear now is the same as I bought yesterday.你现在穿的外套跟我昨天买的一个样。
③as和which指代主句的内容时所引导的定语从句的区别
如果有“正如,象”的含义,并可以放在主句前,也可以放在后面,甚至可以插在主句中间,那么用as;而which引导的从句要放在主句后,并无“正如”的意思。
They won the game, which we hadn’t expected.
他们赢得了比赛,这是我们没有料到的。
