第一句是约定俗成的习语是“你好”的意思其实按语法是错的应该是how do you do it?你怎么做到的?
what do they do?他们在做什么?是可以的
如果这里do做及物动词的话 why does he do?也不符合语法也要加it why does he do it?他们为什么做（某事）?如果是非及物动词就可以了
what 可以作代词特殊疑问句的时候就不要it 而how 和why 是副词不能将it或后面的谓语省略
说的比较清楚了

how do you do?为什么会出现两个do?可以说what do they do?或why does he do? Do you know?What does he do? how does he do what do they do? what do you do 和 how do you do how do you do? how do you do do you know what does he do 和do you know how does he like.这两 “what do you do! What ( ) do you do? what do you do 补全对话 what does he's .do you want yes,.why do you want becaus
