there's good guys and bad guys and some guys in between.这儿为什么用is呢

问题描述:

there's good guys and bad guys and some guys in between.这儿为什么用is呢
还有we've begged her.这句话怎么理解,是已经beg了还是没有 beg?

1there is通常用来修饰一件事情,即把good guys and bad guys and some guys in between这看成是一件事,因为是一件事,单位还是“一”所以用is
2we've begged her,我们已经恳求她了,'ve begged 是have begged 的缩写,是现在完成时
