3)Model Three: (08年1月)：What Electives to Choose? Most universities provide for their students various electives ranging from classical music to modern economics. This practice, a good way to expand students’ horizons and allow them easy access to new fields, enjoys great popularity among students.
There is no doubt that different electives appeal to different groups of students. It all depends. Some of them choose to sit in a classical literature class or an oil painting
class out of interest. These courses are believed to help to fulfill their heart’s desire and contribute greatly to their well-rounded development.

4)Model Four (07年6月)：Welcome to Our Club

It has become a custom for millions of Chinese people to sit through the variety show following the traditional family reunion feast. They simply cannot step into the new year without the gala, which seems as indispensable to the New Year’s Eve celebration as firecrackers.
With the passage of years, however, a growing number
of people begin to view the gala as “chicken rib”骨架, unappealing and worthless, when people can feast themselves on other evening entertainment. Some even throwing away the show, which fails to give its increasingly demanding and diverse不同的audience a convincing excuse to be rooted in the sofa and stay glued 似胶水粘住to the TV. To my eye, the existence of the gala is still justifiable. For one thing, with the variety show characteristics of Chinese tradition aired 播送both home and abroad, it provides the Chinese people, especially those overseas, with a good opportunity to establish their cultural identity on this unique evening. For instance, the gala, a rare occasion of gathering of those performers, is undoubtedly a treat for those in the remote or poverty-stricken areas.
6)Model Six (06年6月)：On Students Selecting Lectures In recent years, students in some college are entitled to the choice of their lectures for certain courses. This practice has enjoyed great popularity since it was introduced.
When selecting teachers, most students will take the following factors into account. In the first place, lectures with impressive academic background and rich working experience are preferable because exposure to inspiring
lectures is a most rewarding experience. In the second place, teachers with a convincing and vivid teaching style are more likely to meet students’ taste. In one sense, it is not what is given in a lesson but how a lecture is delivered that really appeals to students.
Students’ free choice of lectures will bring with its both benefits and problems. On the one hand, this makes it possible that students have easy access to good teachers who may open a new horizon for them. On the other hand, good as the practice may be, chances are that some students will misuse the opportunity and select undemanding lecturers while some distinguished but strict teachers may be unwelcome. It will result in a waste of the teaching resources.
Unquestionably, this issue deserves further attention from both colleges and students. What they should do is to minimize the potential negative effects.
