这几句英文文法对麼?1.Let me know what book you want.2.Which book does he say he wants?3.Which does you say he wants?4.Who do you say is the best student?请帮检查有无错误第四题后面不是应该s+b麼像是4.Who do you say the best student is?

同意“5时时差”的回答 。do you say\\ think\\ believe..可以作为插入语，其后接陈述语序，3句中 you 做主语第二人称，应用do提问

1 ok
2ok
3 not ok
4 ok
3:which do you say he wants?

第三个有明显的错误。you 不是第三人称，不能用does。

1. let me know the book you want
2. which book did he say that he wanted?
3. which book did you say that he wanted?
4. who do you say is the best student?
我觉得应该和do you think一样用法

前两句正确,第三句应是：Which do you say he wants?
是的,第四句应该是.Who do you say the best student is?

1 第三句有问题，除非知道上下文，否则要说：Which book do you say he wants?
2 在Who do you say is the best student 中，who 做主语，所以第四句也是对的。
