He likes playing football.如何给划线部分提问,

一、所谓给划线部分提问,就是提问后的句子还得用划线的词语回答.提问时要注意以下几点：

　　1、用相应的疑问词取代划线部分,并把疑问词放在句首.也就是说,对人提问,用 who 取代；对事物提问,用 what 取代；对时间提问,用 when 取代；对地点提问,用where 取代；对原因提问,用 why 取代；对方式、程度、状态或特征等提问,用how 取代.
　　2、如果划线部分是主语,提出问题的疑问句应该用正常语序.如果划线部分是其他成分,提出问题的疑问句应该用部分倒装语序,即把主语放在系动词后或把主语放在助动词和动词之间.
　　3、如果划线部分包括不定式或者动名词,用 to do 取代划线的不定式或用 doing 取代划线的动名词.

二、下面就 He likes playing football 进行具体分解.（对括号中的词提问）

(He) likes playing football —— he 指人,用 who 取代 ,提问部分是主语,用正常语序
——Who likes playing football?
He likes playing (football) —— football指物,用 what 取代,提问部分不是主语,用部分到装语序
——What does he like playing?
He likes (playing football). —— playing football 指事情,用 what 取代；换线部分有动名词 playing,用doing取代；提问部分是likes 的宾语,用部分到装语序
—— What does he like doing?

三、更多的例句

He likes playing football (after class) —— 对时间状语提问
——When does he like playing football?
He likes playing football (on the playground) ——对地点状语提问
——Where does he like playing football?
He likes playing football (very much) ——对程度状语提问
——How does he like playing football?

哪个是被画线了， 如果是playing football, 那么就直接问What does he like? 如果是He, 那就直接问 Who does like playing football?

What does he like?
