听力原文： If you feel overwhelmed by your college experience, you are not alone--many of today' s college students are suffering from a form. of shock. Going to college has always had its ups and downs, but today the "downs" of the college experience are more numerous and difficult. The schools are responding to the problem with increased support service.
Lisa is a good example of a student in shock. She is a lovely, intelligent girl of twenty and is in her third year at a university. Having been a straight A student in high school and a member of the basketball team there, she remembers her high school days with fondness. Lisa was popular then and had a boyfriend for the last two years of school.
Now, only three years later, Lisa is miserable. She has changed her major four times already and is forced to hold two part-time jobs in order to pay her tuition. She can't sleep well or eat properly. She also believes that she has no close friends. Sometimes she bursts into crying for no apparent reason. On more than one occasion, she has considered taking her own life.
What is happening to Lisa happens to millions of college students each year. As a result, roughly one-fourth of the students suffer from depression. Some of them are so depressed that they have to go to the doctor. Meanwhile, suicide rate among college students is higher now than at any other time in history. It is fifty percent higher than among non-students of the same age. It is estimated that each year more than five hundred college students take their own lives.
College health officials believe that these reported problems represent only the tip of the iceberg. They fear that most students, like Lisa, suffer in silence.
