需要提醒的是,anything, something等后面的形容词从句通常都用that引导,但偶尔也可用which替代that.
如：We have proved that anything which exists is real./ If you have something to say which is on the subject, wait till you have a chance and say it to the whole class. 所以选D是对的.请问一下“偶尔”的情况是什么？在什么情况下which可以代替that？如果两个都出现，还是选that吗？上面一句是我在翻语法书的时候，上面这么解释的。这么着吧，有that优先选that,没that,只能选which.谢谢解答。
