Time and how we experience it have always puzzled us. Physicists have created fascinating theories, but their time is measured by a pendulum（钟摆）and is not psychological time, which leaps with little regard to the clock or calendar. As someone who understood the difference remarked, “When you sit with a nice girl for two hours it seems like a minute, but when you sit on a hot stove, a minute seems like two hours.”

Psychologists have long noticed that larger units of time, such as months and years, fly on swifter wings as we age. They also note that the more time is structured with schedules and appointments, the more rapidly it seems to pass．For example, a day at the office flies compared with a day at the beach. Since most of us spend fewer days at the beach and more at the office as we age, an increase in structured tune could well be to blame for why time seems to speed up as we grow older．

Expectation and familiarity also make time seem to flow more rapidly. Almost all of us have had the experience of driving somewhere we’ve never been before. Surrounded by unfamiliar scenery, with no real idea of when we’ll arrive, we experience the trip as lasting a long time. But the return trip, although exactly as long, seems to take far less time. The unfamiliarity of the journey has become routine. Thus taking a different route on occasion can often help slow the clock.

    When days become as identical as beads（小珠子）on a string, they mix together, and even months become a single day. To fight this, try to find ways to interrupt the structure of your day—to stop time. Learning something new is one of the ways to slow the passage of time. One of the reasons the days of our youth seems so full and long is that these are the days of learning and discovery. For many of us, learning ends when we leave school, but this doesn’t have to be.

“Before you fall in love, you'd better get a job”
As told by Lee Joon-ho, 20, a senior in law at Seoul National University
Korean TV dramas have shown a lot of rebellious(反叛的) youth, but in fact most students still live a traditional life.
Confucianism has a great influence on us. For instance, Confucius said that we should be dutiful to our parents and value the family. Thus we prefer a school that's close to home so we can go back every day.
Also as a result of Confucianism, teachers enjoy a high status in Korea. The other day, my professor was flying to Vienna on a business trip. Instead of waiting for hours in the queue, he was told to check in first and didn't have any problem with overweight luggage.
When it comes to important decision-making, such as choosing a university, a job, and a wife, we listen to our parents' suggestions. Most parents seem liberal in study decisions, but they take a firmer attitude towards their children's love and marriage choices. Often, a man has to have his own business or a solid career before he's allowed to pursue romance.
Male chauvinism is popular among our parents' generation, since they had to support the whole family through hard work. We need to shoulder the same responsibility, but we've also learned to respect women, as they're doing outstanding work in lots of areas. But to be honest, my friends and I still prefer a traditional woman as a girlfriend and future wife. We want her to be elegant and thoughtful in taking care of a family.
Our sense of tradition is also reflected in our buying habits. In my house, you see only Korean appliances. Although European cell phones are available in ROK, we favor LG and Samsung, which are suited more to our tastes and widely promoted in TV dramas and films.
【小题1】The professor was told to check in first because _________.
