he is such a funny sort of person ---i don't understand at all

问题描述:

he is such a funny sort of person ---i don't understand at all
a.who b.that c whom d as
这句话的意思?
AS在定语从句的用法?什么情况下用as
为何不能用B,不是有such as 的用法吗

He is such a funny sort of person (as) I don't understand at all.
这是个含有定语从句的主从复合句,当先行词such (a funny sort of) person 被such修饰时,关系代词用as,另外as在定语从句中作宾语.
He is such a funny sort of person (that) I don't understand (him)at all.
这是个含有状语从句的主从复合句,such...that...如此.以至于.把两句话翻译一下可以?还有,什么情况下用as他是这样一个滑稽的,我一点也不懂得的人。他是如此滑稽的一个人,以至于我一点也不懂他。
