Liberal (自由) education is designed not only to teach and learn knowledge, but also to develop a person’s character. Its aim is to   1  each student to think for himself and make wise decisions. Now liberal education has a great    2 on the world.
Much work has been done to  3  a better way of teaching. In a liberal class, students are  4 to have their own thoughts and own ideas when they have  5  which are often held in the form of group discussion. They are properly guided to   6  the knowledge learned. Punishment no longer exists (存在).  7 and students are just like friends.
The idea is of course a perfect one if it can really be carried out. However, it  8 exists in the imagination and will never be realized. We must admit (承认) that  9  should at least be guided properly. Just close your eyes and think how many students will   10  the duties of a student if they are not pushed.   11 is the use of advice only if it is not supported by a reasonable   12  of  control and punishment?
It is   13  for us to judge the success and failure of the kind of education now, but   14  the bad behavior of children, which is really the   15  of liberal education, we can see that something must be done to help these children.
