It’s nothing to be surprised about

Question

It’s nothing to be surprised about 这个句中的about 起什么作用？是什么意思？去掉可以吗？

Answer 1

本句中的不定式短语可以看作后置定语，about是介词 其逻辑宾语是前面的nothing，所以介词不能省略。改成定从你就明白了，原句=
It’s nothing that we are surprised about.
还原定从即we are surprised about nothing.追问

I appreciate your help

Answer 2

it's nothing to be surprised about的释义,网络释义: 这事不值得大惊小怪;没有什麽值得大惊小怪的;这不值得大惊小怪
[例句]It's nothing to be surprised about. Don't make such a big deal out of it.
这事不值得大惊小怪，不要小题大做。
It's nothing to be suprised about该句中的 it 是形式主语,to be suprised about..才是真正的主语,这是不定式做主语的例子,不能省略.
可以转变为：To be surprised about...is nothing. about不可以去掉追问

本句中的不定式短语可以看作后置定语，about是介词 其逻辑宾语是前面的nothing，所以介词不能省略。改成定从你就明白了，原句=It’s nothing that we are surprised about.还原定从即we are surprised about nothing.
