比如说：
1 He has lunch here
-------Does he have lunch here
你需要用助动词 do / does 参与.do/ does是一般现在时的助动词.
但在英式英语中,在表示“有,拥有”的时候,do/ does可以不用.
--------He has a new bike.- - - - - Has he a new bike?
2 在have / has got 中,have / has已经是助动词了,do / does / did就不可以出现：
They have got a new car.
-------Have they got a new car 虚拟语气的助动词如SHOULD，WOULD，是情态动词吗？你好。是的。请参考------牛津高级英汉字典（第七版）page 1850
