do和does,have和has的用法

do和does,have和has的用法
我知道does是第三人称单数,但是我才学根本不知道单数是怎样表示,我先说说我的想法、用does的时候是不是用在he,she,it,或者一个人的名字,还有的是：My mother's什么什么的时候也要用does,在句子中一个人and另一个人的时候是复数,就必须用do了?一般疑问句的时候格式是什么?还有have和has怎么用,在一般疑问句的时候是只用动词原型吗?be动词的一般疑问句格式还有do/does/have/has一般疑问句和否定句,肯定句的格式请列出来,并且列一个句子我才看的懂.列句子的时候请列初一内容之内的单词.不然看不懂呢

一般疑问句是疑问句的一种.它是指用yes或no来回答的句子.其结构是：
系动词be/助动词/情态动词＋主语＋其他成分?
如:
Is this your pen?
Yes it is./No it isn't.
注意：
1．将陈述句变为一般疑问句时,如句中有be 动词（am is are …）时,可直接将它们提至主语前.如主语为第一人称,应将其改为第二人称.如：
I'm in Class 2Grade 1． →
Are you in Class 2Grade
We're watching TV． →
Are you watching TV?
2．陈述句中有情态动词（can may must …）时,也可直接将它们提至主语前,即可成为一般疑问句.如：
He can swim now． →
Can he swim now?
The children may come with us． → May the children come with us?
3．陈述句中只有一个实义动词作谓语且其时态为一般现在时,变为一般疑问句时要在句首加do或does 主语后的实义动词用原形.如：
I like these animals． →
Do you like these animals?
She wants to go to the movies． → Does she want to go to the movies?
4．一般疑问句一般读升调(↑)
5．一般疑问句有时不用yes或 no 回答.
一、一般疑问句
一般疑问句也可称为 “yes ／ no questions”,因这种问句通常用yes ／ no来回答,相当于汉语中的“……吗?”其语序是：系动词be ／ 助动词／ 情态动词＋主语＋其他成分?如：

Yes I am． ／ No I'm not．
Is her sister doing her homework now?
Yes she is． ／ No she isn't．
Does he work in a bank?
Yes he does． ／ No he doesn't．

Can you speak French?
Yes I can． ／ No I can't．
May I go home now?
Yes you may． ／ No you mustn't．
