1. Students differ about whether they should have their future mapped out when they were still at the university. Some think that they should have a definite goal and detailed plan, so as to brace themselves for any challenges, whereas some others think they don't have to think much about the future, because future is full of uncertainties.

2. 我们觉得在校时间不多了，以后再也不会有这样的学习机会了，所以都下定决心不再虚度光阴。当然，下一年四五月份的期末考试最为重要。我们谁都不想考全班的倒数第一，那也太丢人了，因此同学们之间的竞争压力特别大。以前每天下午五点以后，图书馆就空无一人了，现在却要等到天快亮时才有空座，小伙子们熬夜熬出了眼袋，他们脸色苍白，睡眼惺忪，却很自豪，好像这些都是表彰他们勤奋好学的奖章。
