it was touch-and-go there for a while中there的词性与意思

问题描述

it was touch-and-go there for a while 中 there 的词性与意思？为什么要加一个 there 在这里？

老师答疑

刘老师：

touch-and-go = dangerous
It was touch-and-go there for a while.
“那只是暂时的危险”。
It 在本句中指“情况”。there 意为“那儿”，副词，地点状语，不译出也行。

类似there，here 这样的表达很多，在英语中司空见惯。
It is hot here.

It was very danerous there.
