    A study of 3,884 students from primary schools to colleges found that examinations made 83.1 percent of primary students anxious, and more than 40 percent of high school children were out of sorts （身体不适）because of stress and anxiety.

Moreover, 75 percent of the high school respondents admitted that they had problems talking to their parents and more than 55 percent of them found it hard to associate with other people, according to the study.

It is not difficult to conclude that our children are not happy.

Today's kids are coming home from school weighed down with backpacks full of books and worksheets. They are spending hours at desk at night, seldom going outside to play and getting to bed late.

How can this be a good thing?

Homework is eating away children's time to play freely with neighborhood kids - and more importantly, their time to sleep.

Homework can enrich the education process. But like all things, too much of it may dampen （减 少）a student's enthusiasm for learning. To raise cheerful, contented and well-mannered children, parents need to put in a lot of time and effort. Their eyes should go beyond their children's preparations for tests. Children need a break too. So let them be in control of parts of the day.
