下列形容词、副词、代词从肯定句变成否定句时，须作相应的变化:

肯定句否定句We've had some money.We haven't had any money.I was talking to someone.I wasn't talking to anyone.They sometimes visit us.They rarely (never/seldom) visit us.He has arrived already.He hasn't arrived yet.Li is coming too.Li isn't coming either.Both of us are going.Neither of us are going.He likes both of them.He doesn't like either of them.

注意：“so/neither+助动词/情态动词+名词/代词”结构中须用倒装语序，

如：My wife likes classical music very much and so do I. 我的妻子非常喜爱古典乐，我也是。

She doesn't like jazz and neither do I. 她不喜欢爵士乐，我也不喜欢。
