I haven't ,either. 我也没有。

此处里either是副词，专用于否定的简应句中。简应句有肯定简应句和否定简应句之分。

1. 肯定简应句与so、too连用。与so连用时，简应句须采用倒装结构；与too连用时不须倒装。

eg. He is nice,and so is she ;

= He is nice,and she is,too.

He was going home,and so was she .

= He was going home, and she was,too.

He will come,and so will she .

=He will come,and she will,too.

He has gone,and so has she .

=He has gone,and she has ,too.

He came,and so did she.

= He came,and she did,too.

=He has a book,and she does,too.

He is a doctor, and so is his father.

= He is a doctor, and his father, too.

= She can swim, and I can , too.

He failed the exa,. and so did she .

= He failed the exam, and she did,too.

Tracy sings well, and so does her sister.

= Tracy sings well, and her sister does, too.

*. 在对话中，两句指的是同一个人时，不论句子是肯定句或否定句，均用so引导，且句子不倒装。

eg. A: He is stupid .

      B: So he is.

      A: You can't do it .

     B: so I can't.

     A: She is pretty. ---> B: So she is.

     A: you can't swim.----> B: So I can't .

2. 在否定简应句中用neither、nor、either.

neither , either皆为副词，故and不可省略；nor为连词，前面不必放and.。使用neither,nor时必须用倒装句子结构，而使用either时，须于not连用，不须倒装。

eg. He isn't nice,and neither is she .

=He isn't nice,nor is she.

=He isn't nice,and she isn't,either.

He never tells lies, and neither does she .

=He never tells lies, nor does she.

=He never tells lies, and she doesn't ,either.

He won't come,and neither will she.

= He won't come,nor will she.

= He won't come,and she won't ,either.

= John isn't a student, nor am I.

= John isn't a student, and I am not, either.
