all i have to do is learn english是否错了?
这是在恒星英语那看的李阳疯狂英语IS后面不是不能跟动词原形么?

下列句型中,be动词后的to可以省略,改接原型动词做表语.
All I have to do is (to ) take a good rest.(你所要做的是好好休息）
All I can do is (to)wait.(我所能做的就是等待）
What you should do is simply (to) apologize to him.
(你应做的事就是向他道歉）
All I did yesterday was (to) eat and sleep.(我昨天做的事就是吃和睡）这些句子前都含有do的某一形式,所以可以省略后面to do中的to.
All i have to do is learn english也是一样

all i have to do is learn english是否错了? All I have to do is learn English,看了有些答案说是All I have to do i All I have to do is learn English.这句里learn是动词,前面干吗用is all i have to do is learn english.为什么不是all i have to do is l All I have to do is learn English. 中的learn是不定式吗? All I have to do is learn English.中的learn用法对吗 All I have to do is learn English.这句话语法对吗? All I have to do is learn English 是对的吗请问这个句子中all I have to do is learn english.is跟learn不是都是动词吗?为什么 All I have to do is learn English."all"可以换成"what"吗?换过有区别吗? What I have to do is learn English What I have to do is learn English.
