such...as是一个引导定语从句的固定句型。 as之前的名词充当的是先行词,as在从句中代替名词的含义,又在从句中充当某个成分,也就是说,在such...as句型中,从句总是缺少某个成分。 例如:Such selfish people as you described are not welcome. 在此句中,定语从句缺少宾语。 Such advice as he has given proved almost worthless. 在此句中,定语从句缺少宾语。 Such film as was shown yesterday is not suitable.在此句中,定语从句缺少主语。 通过以上分析,such...as引导的定语从句总是缺少某个成分,这是因为as代替先行词且在从句中担任了这个成分。 such...that的功能。such...that是一个引导结果状语的固定句型,它表示“如此……以致”,在从句中that不担任成分,也就是说,从句中的成分是齐全的,可以省略句中的连词that,也可以将such及其后的名词短语提前,句子构成部分倒装。 例如: It was such a boring speech(that) I fell asleep.(这演讲枯燥无味,听得我都睡着了。)在此句中,状语从句主系表成分齐全。 He is such a dishonest boy (that ) nobody believes him.(他是不诚实的孩子,以致没人信任他。)在此句中,状语从句主谓宾齐全。 The knot was fastened in such a way that it was impossible to undo.(这个结系得那么紧,根本解不开。)在此句中,状语从句主谓宾齐全。 |
