All I have to do is learn English,看了有些答案说是All I have to do is to leatn English,只是省略
了to.我想问一下这句话都做什么成分呢?I 是主语,have to do是谓语前面的all和后面的is to learn English是做什么呢?

all 是主句的主语；is 是主句的谓语；learn English 是省 to 不定式,在定语中作表语.
I 是定语从句的主语；have to do 是定语从句的谓语；关系代词 that 作定从的宾语,但被省略了.
主句：All is to learn English.
从句：（that ) I have to do
动词不定式在作表语时,可以省略不定式符号 to.all 作先词指物时,关系词只能用 that ；关系代词在定语从句中宾语时,可以省略.
句意：我必须做的事情就是学英语.

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.为什么不是all i have to do is l all i have to do is learn english是否错了? 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. 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 “All I have to do is learning English. All I have to do is learn English."all"可以换成"what"吗?换过有区别吗? 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 to do sth
