1.All I want to do is to stay with you和All I want to do is stay with you哪个是正确的?为什么?

1、is to stay with you 正确 因为is 之后要跟动名词结构或者动词不定式结构（to do）
2、staying with /to stay with开头的两个句子是对的,理由同上~
To stay with you is all that i want.就等于 all i want to do is to stay with you
3、不对,to do 动词不定式结构,be to doing是错的,在这里to 之后不能加名词/动名词
All i want to do is staying with you 正确.
有不懂的再问~''is 之后要跟动名词结构或者动词不定式结构'' 是be动词还是只有isbe动词;另外all i want to do is stay with you.还有主谓宾 语法结构方面的问题：出现两个谓语动词。至于有网友提到的语感、歌词可行，你可以去问问中国教学的英语语法可不可行… 在外国可能是可以的
