Do(还是用are) you doing your homework now?如果换成Do(还是用are) you do your homework？

Do(还是用are) you doing your homework now?如果换成Do(还是用are) you do your homework？ -What are you doing?-Doing my homework.还是-Do my homework. 经常在美剧中把What are you doing听成what do you doing.请问是因为口语中省略be动词are所以听起来像,还是真的可以用what do you doing这种错误语法? what do you think you are doing what do you t-----you are doing 到底是do youknow what are you doing还是do you know what you are doing谁能解释清这语法呀 what are you { }tomorrow?括号里应填doing还是will do还是going to do 或go to do what are you doing to do there? what (is are )you (do doing ) now we are also do还是doing. what can you do直接回答?使用Doing还是用Do?what are we going to do?Eat some fish.为什么这个例子是这样回答的 你做这个干什么?用英语怎么说?what are you doing that for 还是what do you doing that for你做这个干什么?用英语怎么说是what are you doing that for还是what do you doing that for how are you doing 还是how you doing? when are you doing sth?正确还是when are you do sth?正确?中文意思是“你什么时候做sth?” thanks for you do 还是doing would you mind not doing还是do? could you please doing 还是do ------you ------your homework now?do/ doing,are/doing ,were/ doing,does /do 选b为什么?
