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，一項調查結果在社會上引起了強烈討論。調查的結果顯示：在城市中有大約一半的學生請家教。一些人認為請家教輔導學生寫作業很正常，而另外一些人則認為請家教弊大于利。

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. 

為何家教如此流行？很多家長，因為某些原因，沒有得到很好的教育。當他們的孩子在學習中遭遇困難時，他們變得手足無措。而請家教就成了唯一的解決方式。

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，請家教能幫助學生提高成績。但實際上，它占用了學生過多的休息于娛樂時間。學生們把所有的時間都花在學習上，都沒有剩余的時間去鍛煉或者出去玩。更糟糕的是，有些老師忙于幫學生提高成績，無意中給學生增加了很多壓力。因此，我認為請家教弊大于利。
