Here's a sentence:
Oh no!The stupid computer has crashed again!
I think crash is used when a plane wreches or something failure,broken maybe better.But our teacher said I was wrong.Am I really wrong?
crash (n) A serious computer failure. A computer crash means that the computer itself stops working or that a program aborts unexpectedly. A crash signifies either a hardware malfunction or a very serious software bug.
If your computer crashes, it is not your fault. If the program is good and your hardware is functioning properly, there is nothing you can do to make your system crash.
crash(v) To fail or break. Other terms for crash include hang and bomb.
wreck, "not wrech"; when a plane crashes, not "when a plane wreches".
