问几道简单的英文改错题~
1.At the party,all the lemonade was drank by the guests.
2.Sharks can be real frightening.
3.The teacher asked Jane and I to perform in the class play.
4.Don Bradman would be the first cricketer to have had an average of one hundred runs.

有些是关于单复数形式的..
请大家帮忙指出来是哪里错了..

答案

1.drank--drunk（被动语态）
2.real--really(修饰形容词frightening应该用副词)
3.I--me (ask的宾语应该用代词宾格)
4.去掉had(现在时)
5.rung--rang(ring的过去式是rang)
