想问大家一个英语语法的问题,关于定于从句的
You should only ask practical,answerable questions based on actual problems that you face.
上面这个句子的based的用法师定于后置是吗,后面的that是定于从句是吧.这个句子是不是也可以
You should only ask practical,answerable questions which are based on actual problems that you face.那么我们平时写email或是口语应该怎么表述类似的句子呢,就是到底应该如何用比较好
