D  

Japanese students work very hard but many are unhappy.They feel heavy pressures from their parents to do well in school.Most students are always being told by their parents to study harder so that they can have a wonderful life.Though this may be good ideas for those very bright students,it can have very bad results for many students who are not quick enough at learning.

Unfortunately,a number of students killed themselves.Others are after comfort in using drugs.Some do bad things with trouble-makers and turn to crime.Many of them have tried very hard at school but have failed in the exams and have disappointed their parents.Such students feel that they are less important and leave school before they have finished their study.

It is surprising that though most Japanese parents are worried about their children, they do not help them in any way.Many parents feel that they are not able to help their children and that it is the teachers' work to help their children.To make matters worse, a lot of parents send their children to special school called juku-cram schools.These schools are open during the evening and on weekends, and their only purpose is to prepare students to pass exams, they do not try to educate students in any real sense of the real world. It thus comes as a shock to realize that almost three quarters of the junior or high school population attend these cram schools.    

Ordinary Japanese schools usually have rules about everything from fhe students' hair to their clothes and things in their school bag.Child psychologists now think that such strict rules often lead to a feeling of being unsafe and being unable to fit into society.They regard the rules as being harmful to the development of each student.They believe that no sense of moral values is developed and that students are given neither guidance nor training in becoming good citizens.
