比较so和 such
其规律由so与such的不同词性决定.such 是形容词,修饰名词或名词词组,so是副词,只能修饰形容词或副
词.so 还可与表示数量的形容词many,few,much,little连用,形成固定搭配.
so + adj.such + a(n) + n.
so + adj.+ a(n) + n.such + n.(pl.)
so + adj.+ n.(pl.) such +n.(pl.)
so + adj.+ n.[不可数] such +n.[不可数]
so foolish such a fool
so nice a flower such a nice flower
so many/ few flowers such nice flowers
so much/little money.such rapid progress
so many people such a lot of people
so many 已成固定搭配,a lot of 虽相当于 many,但 a lot of 为名词性的,只能用such搭配.
so…that与such…that之间的转换既为 so与such之间的转换.
