Xiao Pan, what's wrong? You look a little anxious.

Teacher, my USB drive isn't responding. The computer can't detect it.

Don't worry. Let's check it step by step. Did you plug it in properly?

I plugged it in, but there was no sound and nothing appeared on the screen.

Okay, try another port. Sometimes a port doesn't work properly.

I tried it, and now it works!

Very good. When you run into a problem, don't panic. Check things slowly first.

I understand. I was too anxious just now and didn't think it through carefully.

Right. You need to stay calm at work so you can make fewer mistakes.
