I have learned to use "expect" for only good things. But is "expect" used to both good and bad things?
Yes, the word "expect" can be used in both good and bad situations. When used in a positive context, it usually means that you are looking forward to something happening. Ex: I'm expecting to go to college next fall. Ex: We are expecting a baby. When used in a negative context, "expect" often refers to something you didn't see or anticipate happening. Ex: They didn't expect that the earthquake would damage their home. Ex: He didn't expect to lose his job.
