No sweat 沒問題
No sweat 是一個非常口語化的表達，意思是指什麼事情很容易，舉手之勞，沒問題。
Sweat allows the human body to regulate its temperature. Men sweat more than women and humans sweat more than most other animals. Dogs have relatively few sweat glands and moderate their temperature by panting.出汗是人體調節體溫的正常反映。男人比女人更容易出汗，而人類比大多數動物都更容易出汗。狗的汗腺較少，它們是通過舌頭喘氣來調節體溫。
"Can you take the rubbish out for me?" "Sure, no sweat!"
"We only have tea to drink, is that OK?" "Yeah, no sweat."
另一個短語 to sweat blood 和 no sweat 的意思正好相反，指為了辦成什麼事情而做出了很大的努力，花了很多心血。
We sweated blood to get the project done on time.
