找出英语句子中的错误并改正
1 i was soory to hear you have a cold last night (was to have have)
2 her math is much bad than mine ( her bad)
3 his grandpa is over seventy ,but he is still at good health ( but at health)
括号里的是 有下划线的 选项
句型转换 ‘’ you can do better ’,her mother said to her.
her mother sai ----- ------ ------ ------ ------ -------
需要简要说明理由 ,

1.have --had 过去时
2.bad- worse 比较级
3. at- inin good health是固定搭配
He mother said that she could do better. 直接引语便间接引语, 人称、时态要变
