Question

am not, aren't, isn't, can't, don't doesn't

这些词分别在上面情况下使用，麻烦懂的说明下。
he likes coffee，but i don‘t
she likes tea,but he doesn't
he is eating some bread,but she isn't
she can type very well,but he can't
they are working hard,but we aren't
he is reading a magazine,but i am not
为什么这样用，请说详细点说，还搞不懂怎么用

Answer 1

he likes coffee，but i don‘t 【like coffee】
（ 这里主语为 I，对动词like 表示否定，借助于don't）
she likes tea,but he doesn't【like tea】
（这里主语为he, 对动词like 表示否定，借助于doesn't)
he is eating some bread,but she isn't【eating any bread】
( be动词is，否定直接加not，为isn't ）
she can type very well,but he can't【type very well】
（can 否定形式，直接加not，为can't）
they are working hard,but we aren't【 working hard】
（be 动词are, 否定直接加not，为aren't)
he is reading a magazine,but i am not 【 reading a magazime】
( be动词am, 否定直接加not，为 am not )

追问

最后条be动词不is吗？

追答

I am 搭配在一起的

追问

那第一条不也是I吗？为什么不和am一起而是直接don’t

追答

有be动词的情况下，直接加not 表示否定，对动词表示否定借助于don't, doesn't.

可以采纳，再提吗？谢谢

你是想知道当I'm...,_____?反意疑问句的附加提问如何选吧？应选aren't .
如：I'm late again,aren't I?
