Reading comprehension.

     Teachers say buying homework answers online is not many in schools, but an interview with school

students shows only 10% are willing to finish their holiday homework by themselves. Their main complaint

is that the homework is too much for them to finish.

     "As far as I know, many of my students have to go to all kinds of training classes during the holiday.

These take away much of their time for doing homework."

     But as for the parents who are sending their children to these training classes they also say they've got

no choice. Here's a view from a student's father.

     "All the other kids in the neighborhood are learning extra things. You know parents sometimes compare

their kids. I'm afraid my kid will be less successful than the others in the future."

     In order to do with this situation of students copying each other's homework, some schools have even

dropped the idea of holiday homework. Instead, they organize some interesting outdoor activities.

     Educational experts say students love to learn through games or activities that they can be a part of.

They suggest schools drop the current (目前的) homework format (设计), and turn to homework that

encourages kids to get involved (参与). This way, they would no longer want to copy from each other or

buy answers through the Internet.
