【英语】 My uncle has a son【变成否定句】像这样have或者has的怎样变?

My uncle doesn't have a son .
是这样吗？不太明白你想怎么变。。。

为你解答。
My uncle has a son. （变成否定句）
My uncle doesn't have a son.
我的叔叔没有儿子。
解释：如果是have，就在之前加上助动词don't变否定。如果是第三人称单数形式has，就要加上助动词doesn't，然后has改成原形have，就可以了。

My uncle doesn't have a son.

My uncle doesn't have a son.
或者My uncle hasn't a son.
第一种更常用。

如果主语是第三人称单数,在主语后加上doesn't,谓语动词变为原型
如果不是第三人称单数,在主语后加don't,后面一样
这题是My uncle doesn't have a son
