| Middle school days are both fun and busy. Students spend their days in class, listening to the interesting and __1__ boring words of the teacher. They spend the short breaks running, playing, and shouting happily __2__ going back to the classroom again. But __3__ should students spend their free time outside school! In western countries, it is ordinary for students to have a part-time job after school and at weekends. Students can make their own money and learn more about the "__4__world". They enjoy the independence (独立) and (of course) money, and parents enjoy the quiet house. __5__, it seems that, in China, parents __6__ so much about their children's studies that they would prefer to see their children __7__ most of their free time studying and preparing for all those exams. It is natural for __8__ to feel that way in China, but I believe the answer lies in balance. Sometimes, western school children work long hours after school to make money, and so they become too tired to listen in class or have no time for homework. But Chinese students spend __9__ much time on their studies that all else become less important until they want that new MP4 player. So, find a good and healthy balance! If you have a part-time job, you'll be __10__, and your parents will also be happy because you're spending the money you make and not theirs!
