stress 同 pressure 有何分別??

stress 同 pressure 作名詞用都解作壓力，但意思是有一點不同的。

pressure (noun = 壓力, verb = 施加壓力)
stress (noun = 壓力，緊張, verb = 強調)
stressed (adjective) 緊張

pressure 是外在的，例如 financial pressure, work pressure, pressure from boss, pressure from peer, etc.

stress 是精神上的，也可說是受到外來壓力的內在反應。

在沒有特別指明是那種壓力的情況 stress 也可指外來壓力。

作為名詞 stress 同 pressure 多數情況下是可以互相替代的。

e.g.
You need to be able to handle pressure in this job.
Not many people enjoy the stresses/pressures of city life.
Stress is often a factor in the development of long-term sickness.
He was pressured into accepting the agreement.
People feel stressed under financial pressure.

「pressure... 我們感覺 唔到」這是 layneegispooop說的，我並沒有如些說。
