原句变为否定句有两种方法：
1、在 has 前面加否定助词 doesn't （因为是第三人称单数），has 还原为 have；
His brother doesn't have two football.
2、在 has 后面加 not，has not = hasn't，其他不变。
His brother hasn't two football.
两种变法意思完全一样。
His brother has two footballs.
变否定句： His brother doesn't have two football.
His brother doesn't have any football
