改为否定句

Mike said nothing at the meeting.

I have nothing important to tell you.

Something 改为Nothing即为否定句

Mike didn't say anything at the meeting.
I haven't anything important to tell you.
前一句，否定动词过去式，用didn't something 改为 anything
have的否定形式是haven't.

Mike said nothing at the meeting
I have something important to tell you
否定句用nothing表示什么也没有

Mike didn't say anything at the meeting.
I haven't anything important to tell you.

Mike said nothing at the meeting.
I have nothing to tell you.
something的反义词就是nothing

1. Mike didn't say anything at the meeting.

在这里not...anything就等于nothing

所以Mike said nothing at the meeting.也可以的.

2. 同理
I have nothing important to tell u.
I haven't anything important to tell u.
