读写任务

阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

Nowadays, the pressures on schools and teachers are often passed on to students and parents. Students are tested more and assigned more homework. In the past 25 years, homework assignments have risen by 51% according to a 2008 study at the University of Michigan. That is an average of 12 extra hours of homework per week!

Excessive homework often leaves no time for students to have fun or do something for themselves. Many parents spend at least three hours every night going through their children's work.

However, the governments' efforts to cut the homework burden of primary and middle school students have drawn mixed reactions.  Ironically, though teachers have been widely criticized for piling on homework, it is parents who sometimes ask for more work for their children! When teachers don't give homework, some parents will go to the school and complain. They want teachers to assign homework every day as a means of making sure teachers do their job and the children have work to do.
