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,只要记住这两点就可以了.只要遇到从句在后就可以这样判断,一定正确.如
Tom came late again,as is often the case.
Tom came late again,which didn't surprise all of us.

which 不能做定语从句的主语啊，as可以

other ways of doing things做事的方法，用as引导

当从句放在主句之前的时候，只能用as来作关系代词来引导定语从句，放在后面的时候，与which的用法可以互换，但两个同时在这里摆出来，既要引导定语从句，又要带有“如、像其他国家的情形一样”的话，那么as应该是最佳选项。
