加油 (jiā yóu): oil, refuel, make an all-out effort

I have an exam tomorrow; I need to work hard to review.

When my friend faced difficulties, I cheered him on.

Let's all cheer for the athletes together!

Come on! You can definitely succeed.

The car is almost out of gas; we need to go to the gas station to refuel.

Good luck on the exam! I believe you can do well.

During the competition, the spectators cheered loudly for the athletes.

Let's all make an extra effort together and try to finish the task ahead of time.
