What is your name?和What name is yours?是一样的意思吗?第二句的语法对吗?

What is your name?你叫什么名字?也可以说May I know your name?
What name is yours?问名字的时候what 不做定语,要做了就逻辑表达不清楚,所以错误!
What is your job?你做什么工作?也可以说What do you do?或What are you?
What job is yours?错误同上!
Is this your bandbag?正确
Is this bandbag yours?正确.因为this 和your都能放在handbag前做它的定语,并且逻辑表达清楚.
Whose short is that?正确
Whose is that short?正确.原因同上.
Whose is your short?错误.翻译：谁的是你的短裤?逻辑表达不清楚.
Whose short is yours?翻译：谁的短裤是你的?逻辑表达不清楚.
Is this short Tim’s?正确
Is this Tim short?错误.正确应该：Is this Tim's short?
Do you speak English?正确.因为do,did,does帮有实际意义的动词,即实意动词提问,此处speak为实意动词.
Are you speak English?错误.因为am is are帮名词或形容词提问,比如：Are you a teacher?(a teacher是名词)Are you tall?（tall是形容词）
或者就像刚那位朋友说的Are you speaking English?此时are对实意动词的ing 提问,表示正在做什么吗.
