关于 he's not 和he isn't

Question

我在学习新概念英语.请问.在句子 He's not reading his newspaper at night中.He's not 是否可以改成 He isn't.即He isn't reading his newspaper at night.如果不能为什么.

Answer 1

两者可以互换的啊!He's not是缩写，He isn't 是He's not 的原形．两个句子的意思也是一样的啊，只是用不同的形式表达．

Answer 2

当然可以
这里的He's = He is
isn't = is not

Answer 3

可以改。
