请问英语高手：What can I do?和 How can I do?哪句是正确的,要从句子结构上来分析
看上去都对,那么究竟哪个是对的

第一个是对的,
第二个应该是how can I do it?理由：do是及物动词,其后必须有宾语,无论是陈述句还是疑问句.
但是第一个中,do的宾语是what（什么）,所以第一个对
再问：高手我还想问一个：I do not know how to do it. “how to do it”这个句子，主谓宾在哪里？【谢谢高手了！！！！！】
再答：主语是how谓语是不定式to do。宾语是it其实 “how to do it是konw的宾语从句。

请问英语高手：What can I do?和 How can I do?哪句是正确的,要从句子结构上来分析 what can i do 和how can i do “how to do it和“what to do",请高手为我从句子结构上分析, What can I do better 和How can I do better? how can i do 和what can I do哪个表述更地道? ( ) can i do?填what 还是how what can I do how to do,what to do,what i can do的用法请问What can i do heh,I do myself是什么意思, Can you do what I can do? do you think what i can do? 和what do you think i can do ?谁能帮 I‘m not happy.How can I do?还是What can I do?
