In my spoken English class, I asked the students about their impressions of their university life. To my surprise, many of them expressed disappointment. After their highly controlled high school lives, they were having difficulty adjusting to the free time in the university. When I asked them to describe their high school lives, many of them told me they got up at six in the morning and studied until ten at night. Most of this time was spent at school, doing piles of homework to help them prepare for the university entrance exams.
Once they entered the university, in my opinion, the students are not expected to devote all their waiting hours to studying; they should also take an active part in social activities. Therefore, they should learn to divide their time outside of the class between sports and clubs. What's more, they should spend some time watching TV and chatting with their roommates. These activities are useful in helping them prepare for their future. But what struck me most was that many of them did not seem particularly happy about their new found freedom. As they had so many choices, they felt that no matter what they were doing, they should be doing something else. That's why they were not happy.
To those students, my advice is to get used to it and learn to make decisions for yourselves.
