解答
He helped his mother do housework.
解析：help sb.do 是省to不定式,help后面的动词要跟原型,所以,过去时改为helped sb.do,不可以是help sb.did.
推荐
he often help his mother do the housework.哪里错了
He never help his mother do the housework.(改为反意疑问句)
Does Jim help his mother do housework(该陈述句） Jim( )his mother( )housework
he usually---(help)his mother do some housework on sundays.
( )------_____does he help his mother _____housework?------Twice a week
