Question

what is your name 主语是what？

Answer 1

根据动词或者动词短语来判断.
像What is your name中,what是表语.
What do you like best?这里what是宾语,因为答句I like English中English做like的宾语,而English是用来回答what的,所以what在这里是宾语.
what are you talking about,这里面what也是宾语,因为他是回答短语动词talk about的宾语的,比如答句：we are talking about the new teacher.
What has made you so angry这里面what是主语,因为它对应答句The dog has made me so angry中的主语the dog的

Answer 2

不是。把这个句子改成陈述句，即Your name is what?便可看到what是表语。本人去年高考131，请放心采纳。
