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
am not, aren't, isn't, can't, don't doesn't
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 )
再问: 最后条be动词不is吗?
再答: I am 搭配在一起的
再问: 那第一条不也是I吗?为什么不和am一起而是直接don’t
再答: 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
