這些詞作為疑問詞引導(dǎo)特殊疑問句時(shí)用疑問句語序
你舉的例子：What time do you get up?How many people are there in the classroom?
當(dāng)這些詞,作為連詞引導(dǎo)從句的時(shí)候,后面用陳述句語序.
比如：I want to know what time you got up.
How many people there are is not important.
當(dāng)句子中存在情態(tài)動詞,be動詞或者助動詞時(shí),疑問句可以直接將這些動詞提前.
比如：How long have you been in Shanghai?句中的have 是助動詞,直接提前了.
如果句中只含有實(shí)意動詞時(shí),需要加助動詞did/do,一般過去時(shí)用did,一般現(xiàn)在時(shí)用do或者does
比如：What time do you get up?
What time did you go home?
How often does he watch TV?
這3個(gè)句子分別對應(yīng)了3種助動詞,你參考下.
