1.he____a mistake and i told him to______exercise again.
2.he_____business in australia and______a lot of money.
3.i know you are___your best but you are not___very much progress
4.after i had______the beds,i went out and____some shopping.
这个我想应该是这样的1.made,did 2.does,made 3.did,made 4.made did
这样对不对呢，大家给我看一下然后给我解释一下谢谢了
參考答案:.he_made(表示过去)___a mistake and i told him to_ do（动词不定式to后面要用动词原形）__exercise again.
2.he_does__business in australia and__makes____a lot of money. And联接的两个时态要一致，这个句子就是一般式
3.i know you are_doing__your best but you are not_making__very much progress 有are做提示，表示正在进行式。
4.after i had__made__the beds,i went out and_did___some shopping.
