The British are not so familiar with different cultures and other ways of doing things,______ is often the case in other countries.
A.as B.what C.that D.which
为什么不能选D?

这是定语从句,从句在主句后,这种时候有两种可能,as和which.其它不可引导.但它们两个有所区别.即 as+be+n/p,p 也就说as后能接系动词,然后再接表语.但which不能接系动词,但which后能接否定句,而as不能,只要记住这两点...which不能接系动词?但是课本上有这样的例句哦He married her, which was natural.which后可接系动词但表语通常中形容词。as后接第动词再接the case 或过去分词,这都是固定表达方式。
