Recently, an investigation has caused heated debate among the society. The result of the investigation has showed that about 50% of students in cities have private tutors. Some people think it’s quite necessary to hire a tutor to help the students with their homework, while some people argue that hiring a tutor has more disadvantages than advantages. 

最近，一项调查结果在社会上引起了强烈讨论。调查的结果显示：在城市中有大约一半的学生请家教。一些人认为请家教辅导学生写作业很正常，而另外一些人则认为请家教弊大于利。

Why private tutoring is so popular? Well, many parents, for different kinds of reason, did not have the chance to receive a good education. When their children have problems in their study, they become helpless. Turn to the tutors for help seems to be the only solution. 

为何家教如此流行？很多家长，因为某些原因，没有得到很好的教育。当他们的孩子在学习中遭遇困难时，他们变得手足无措。而请家教就成了唯一的解决方式。

On the surface, hiring a tutor can help students to improve their marks, but in fact, it takes up too much time of the students’ time that they will have no time for rest and entertainment. They spend all their time on study, they don’t have time to do exercise or play outside. What’s more, some teachers are eager to help students to do well on the exams, offering unnecessary tasks for the students, in this case, the students burden will be very heavy to some degree. Thus, I think it’s not necessary to have private tutors. 
表面上看，请家教能帮助学生提高成绩。但实际上，它占用了学生过多的休息于娱乐时间。学生们把所有的时间都花在学习上，都没有剩余的时间去锻炼或者出去玩。更糟糕的是，有些老师忙于帮学生提高成绩，无意中给学生增加了很多压力。因此，我认为请家教弊大于利。
