大虾们，我想知道have had has 怎么区分啊，哪种句型用哪个？多谢

Question

我词汇量还可以，就是这块语法不懂。

Answer 1

have ，3单形式has，过去式过去分词had
have：1.实意动词，有，拥有=have got
I have (have got) a happy family.
He has (has got) a good friend.
She has (has got) an expensive watch.
2.have a ... 从事。。。活动
have a swim=swim, have a bath=bath, have a talk=talk
3.做助动词，辅助构成完成时态，
现在完成时态：have/has +动词过去分词
I have had breakfast.我已经吃过早饭了。have是助动词，had breakfast，had是have实意动词的过去分词形式，这里表示吃早饭
过去完成时态： had+动词过去分词
He had finished his homework when his father came back home yesterday.
昨天他爸爸回到家时他已经写完作业了。

仔细看看例句，希望能帮到你啊！

Answer 2

have实意动词意思是有，做有时还可用于疑问词表示有无东西或做了某事，has是他的单三形式had是它的过去式它们通常用于完成时。have has用于现在完成时，had通常用于过去完成时完成时的构成是have has加过去分词。
