们对我国石油工人冲天劲感到惊奇。

A deep-rooted tree is leafy;an ambitious man is vigorous.

根深叶才茂,志壮劲高。

With his brains and energy, he’s got it made.

智慧和劲，这件事十拿九稳。

As soon as he arrived at the workshop, the technician attacked the difficulties at once.

技术员一到间就立即劲十地着手解决困难。

I was just getting up steam to get to the summit of mountain.

我正劲爬上山顶。
