這裡說的加油是指給某人精神上的鼓勵，如果想知道給汽車加油的英文，請參考相關詞。
I am rooting for you. = I am pulling for you. = 加油! 我支持你! 可用在任何需要加油的情況，例如:
I am rooting for you to get that promotion. = 我為你加油，希望你升官!
Go Michael! = 加油，Michael！
You can do it! = 加油！你能做到的！
lift his spirits = cheer him up = 給他加油打氣，讓他心情變好或豁然開朗
cheer for/on 跟 root for 都指替某人或某隊伍加油，通常會用歡呼的聲音來加油。也可以指替某團體或隊伍加油打氣的意思，通常是在公眾場合做這件事情，例如在球場上球迷為自己喜歡的隊伍加油，如:
The players and the coach are cheering on the batter, supporting the batter vocally.
We are cheering for you = 我們為你歡呼，幫你加油!
對一個人說「加油!」的最好的翻譯之一就是 Keep it up. 或 Keep up the good work. 或 Hang in there.。都有勉勵人的意思，但得依照各種情況翻譯，例如孩子在寫功課，父親可以鼓勵他說 Hang in there. You are almost done.，但有時候卻不會這麼說，例如有人跟你說「我今晚會公開演出」，你不能說 Keep it up.，而會說 Good luck. 或 Break a leg.，所以得依情況翻譯。
Good luck 雖表面上的意思為 "祝你幸運"，實際上也就表示我為你加油。
Hang in there = 撐著點，用在對方已經在做某件事情，並持續當中
當孩子考試成績很好，你可以說 keep it up 或 keep up the good work 表示對孩子的鼓勵跟打氣。
Cheer up! 是安慰難過的人所用的英文
鼓勵人做某事 = Go for it!
pep talk 指打氣的話。
「加油打氣」也可用白話翻譯，例如鼓勵人別放棄就可說 Don't give up.
Don't worry = No sweat = 別擔心，加油!
I have faith in you = 我對你有信心，加油!
I am on your side = I am with you = 我支持你或我挺你
I have your back = 我支持你或願意在別人面前捍衛你
Keep your chin up = 別灰心或別氣餒，加油!
Go get them = Go get 'em = 鼓勵對方的話，有加油的感覺
