助动词该加在什么地方?
——him a few words of Italian?横线处该填Who taught 还是 Who did teach .
——him a few words of Italian?横线处该填Who taught 还是 Who did teach .
who 特殊疑问词在疑问句中做主语,所以不用填did ,该填Who taught,如果who 作宾语就要用助动词,如Who do you want to play with?
但如果是where、when、why、how引导疑问句时一定要有助动词,因为这些都是疑问副词不能做主语,what 做主语时不用助动词,作宾语时要用.例句：
Who broke the window?
Where did Tom go last Sunday(=Did Tom go where last Sunday)?
What happend yesterday?
What do you want to eat（Do you want to eat what）?
不清楚的时候就按括号里的哪样变一下顺序就清楚怎么用了
