Open F2F Class notes 3rd September (Eddie)

short circuit = 短路

motherboard = the most important part of an electronic device

to last v = to endure

E.g. My phone’s battery does not last very long.

I took my phone to a repair shop.

If it ain’t broke, don’t fix it. = when something is working fine, don’t try to improve it too much.

ain’t  = isn’t
= aren’t

Don’t look a gift horse in the mouth.

authentic = true, genuine, the real thing, not fake, original

E.g. This restaurant serves authentic Sichuan food.
