     A popular student in her small high school, Katie started college expecting to do well in her courses and be

best friends with her roommates. But things didn't turn out that way. Psych 101, the course she thought would

be a first-semester favorite, turned out to be a struggle. And her roommates were as different from Katie as the

student restaurant' s mystery meat was from her mom' s roasted pork.

     Living away from home tends to be the toughest adjustment for first-year students. You may feel homesick

in your first weeks or months. It can help to call, write, or email your parents and friends making them know

how you're doing. You can also talk with your roommates. As first-year students themselves, they're probably

experiencing many of the same fears and worries that you're dealing with.

     But what if you don't get along well with your roommates?

     In some cases, it can be a good thing if you and your roommates aren't much alike. Different views on things

may be helpful, so respect your differences no matter what they are.

     If you and your roommates don't get along well, it can help to find someone who you feel does understand

you, which should be easy on a campus with so many people. Many schools have student organization nights

where all of the campus clubs gather and promote their organizations, so you can meet people with the same

interests there as you. You'll also meet tons of people in class or in your dorm building.

     As homesickness, painful throats, sprained (扭伤的) ankles and wisdom teeth that act up are common

among college students, you should check out your student guidebook or your school's website to find out

information about the university health center.

     If you think you cannot deal with your problems, make a stop at the school counseling (咨询) center. First-

year troubles are something the counselors know well. You can get help there.
