1:What books do you read?2:What class are you in?为什么第一句用do第二个用are?
举例说明

▼优质解答

答案和解析

都是一般疑问句,第一句中有read,对动词提问,要加助动词,就是do了,而第二句没有动词,不用助动词用be动词就行了,be动词就是is.am.are.
要举例对吧：你去哪了?有动词去所以 Where do you go
如果是第三人称,就要用does 如果是过去式就要用did,
例句：你刚才去哪了?Where did you go just now
第三人称：他刚才去哪了?Where does he go just now
就是这样了.
