在肯定句中，主语是（I, we, they）时用have，主语是第三人称单数he, she, it 时用has
在疑问句和否定句中无论什么人称作主语，都用have。
Something, everything等做主语时用has。Each of加名词做主语时用has。
复数主语开头加each，如they each仍旧用have.
had 是has和have的过去式。
◆用法：
1、has have had也可以作为一般动词，意为“拥有”“进行”“吃”“使得”“让”等。如果后接不定式，意为“不得不”。例如：
a) He has a good pen. 他有一支好笔。
b) We have supper at 6:00. 我们六点钟吃晚饭。
c) I had my hair cut yesterday. 我昨天理了发。（我让我的头发被剪了，昨天）
d) I have to leave now. 我得走了。“have to do sth必需做某事，不得不”
e) Can I have a toy? 我可以要一个玩具吗？
2、如何变疑问句？一般现在时时,借助助动词do/does.现在完成时时,则直接将have/has提到句首。例如：
He has big eyes. -- Does he have big eyes?
女生古风网名He has finished his homework. -- Has he finished his homework?
3、后接过去分词，构成现在和过去完成、完成进行时。例如：
a) He has gone to Beijing. 他已经到北京去了。
b) I have been a teacher since then. 从那时起我就一直当教师。胃药有哪些
c) They had left when I got there. 我到那里的时候，他们已经走了。
