同学你好~
she's是she has的缩写
has和后面的put以及had构成现在完成时，也就是have+过去分词形式。

常见缩写：

1. 表示“是”的缩写
I'm = I am
He's = He is
We're= We are

2. have的缩写
He's got=He has got
I've got= I have got

3. not的缩写
don't = do not
haven't = have not
won't = will not
haven't = have not

4. will的缩写
I will = I'll
I would = I'd

5. There be的缩写
there's = there is
there're = there are

祝同学学习进步~
