have 和has 过去式后能不能加 not,变成hadn‘t?
可以啊,有这样的缩合形式的
have not=haven't
has not= hasn't
had not= hadn't
再问: 那如果说是 他昨天早上没吃早餐,应该用 He hadn't breakfast yestday morning..还是He didn' have breakfast yestday morning.
再答: 应该用后面那种,因为是表示昨天没有吃早饭,应该用过去时,had done句型是过去完成时,表示过去的过去
have not=haven't
has not= hasn't
had not= hadn't
