动作词自己不能直接说 not。它们要请 do 家族来帮忙。
规则：实义动词不单干，do / does / did 来帮忙。例句：I do not like apples. / She does not play football. / They did not run fast.
I like apples.
把这句变成否定句。
She plays football.
把这句变成否定句。
They ran fast.
把这句变成否定句。
We eat lunch.
把这句变成否定句。
He watches TV.
把这句变成否定句。
I ate lunch.
把这句变成否定句。
They played yesterday.
把这句变成否定句。
做完啦！你已经会用 do 家族把动作词变成否定句了。
