.改成否定句或一般疑问句

Their English teacher gives exams every week.改成否定句和一般疑问句.到底用do 还是用dose .并说明为什么？这里do和does区别在哪里呢？我正在学习英语，很多地方不明白，请资深人士帮忙解释一下。谢谢大家了。

Answer 1

你好,应该是：

要用does

因为主语是their English teacher,为第三人称单数
而时态为一般现在时，所以助动词词要用does

否定句

Their English teahcer doesn't give exams every week.

一般疑问句

Does their English teacher give exams every week?

their是第三人称单数？

追答

主语是their English teahcer,他们的英语老师,是三单
不是their

Answer 2

看到gives了没？？ 单数形式~~ 另外 their enghlish teacher也是单数， 否则就是there english teachers了，后面也会变成give而不是gives .
所以要用DOES。
