定语从句介词提前和不提前怎么分呀
This is the question about which weve had so much discussion.
Have you met the person that he was speaking about.
这两句都是定语从句.从句中一个是discussion about,一个是speaking about.为什么前一句把about 放到了关系代词which前,而后一句不动?如果改成This is the question which weve had so much discussion about.
Please wait for me!wait作谓语，而please和 for me做什么语呢？

答案

如果是 固定的动词词组 则词组中的介词不能提前 要是不是固定的词组 则介词可以提前!
1、第一句中用的引导词是which 在英语定语从句中 就有 介词+which 这样一种语法 可是没有 介词+that 这一用法的 要想把介词提前 只能用which的
2、This is the question which weve had so much discussion about.正常时这样的句子 但是在英语中只要不是固定不可拆的动词词组中的介词 都是默认拿到前面去的!
3、Please wait for me!wait 这是一个祈使句 其中wait for 是谓语 me 是宾语 Please 是祈使句的语气词 !
希望可以帮到你喔!
