So/such・・・that..句型如此. .以至于句型so +adj /adv+that
①当出现不可数名词或名词复数时,与such….that
连用

②当出现可数名词单数时,so 与形容词不分,such 与a/an 不分
such a clever boy so clever a boy
③ 当名词前有many much few little 修饰时,用so ….that
感叹句的用法与此句型类似,what 相当于such how 相当于so 即若感叹句中出现不可数名词或名词复数时,感叹句要用what 来引导若感叹句中出现
可数名词单数时:what a clever boy he is!How clever a boy he is!
so that 可引导目的状语从句,也可以引导结果状语从句。
He worried so that he couldn ' aleep.他急得睡不着。
