couldn't“kodente”
题目矫正：couldnot改为could not
解答过程
could not的意思是不能，could not的缩写的变法是：
将单词之间的空去除
将not的o去掉改成'
即为couldn't，读法也会改变由原本的could not“kode naote”变为couldn't“kodente”。
累死缩写
you are→you're
you will→you'll
she will→she'll
例句
You couldn't to do something你不能去做某事
she couldn't go to school on time她不能准时到学校
