Question

小语法问题。you can do want you want. you can do want you want to. you can do what you want to do.

you can do whatever you want.
这四句话怎么都对吗，为什么。
前两句what 错打成want了

Answer 1

口语上, 这四句话怎么都对

写作上, you can do whatever you want.较好.

Answer 2

都对。want 后可接n做宾语，也可接to do sth 作宾语，即 want sth 或 want to do sth，第一个sth做 want‘想’ 的宾语，第二个 sth 做 do‘想要做’中‘做’的宾语
1.you can do what you want。是由what引导的宾语从句，what引导的宾语从句做do的宾语。在从句中，what是名词性，相当于sth.做want的宾语。
2。you can do what you want to do。同样是由what引导的做第一个do的宾从；在宾从中，what又做want to do中do的宾语；
3.you can do whatever you want。whatever是‘任何事’ .在该句中宾从由whatever引导，在从句中做want 的宾语
4.you can do whatever you want to do.whatever是‘任何事’ .在该句中宾从由whatever引导，在从句中又做want to do 中do 的宾语

Answer 3

1.you can do want you want
是不是打字错误了？ 应该是you can do what you want. 如果是这样的，这4句都对

1.you can do what you want.
实际中经常用到，从语法的角度看，省略了 to do 。
2.you can do what you want to.
实际中经常用到，从语法的角度看，省略了 do
3. you can do what you want to do.
语法正确，实际中偶尔用到。
4.you can do whatever you want.

特别常用。语法正确。
