Dear Editor,

I’m a middle school student. I’m writing to tell you about children who are left-behind(留守儿童) in towns around the country. Now, our city is b 小题1:   more and more modern. That makes a lot of p 小题2: leave their hometowns to work on building the cities. But when they work in the cities, their children are waiting for them at home. One of the most s 小题3:  problems is the loneliness. These left-behind children feel always l小题4:  and stressed out because they have no parents’ love. At the same time, nobody can teach them the differences b小题5: right and wrong. So , it’s easier for these children to make m小题6:   even break laws. It’s very important for us to pay more a 小题7: to these children if we want to build a harmonious society.

So how do we s 小题8:  this problem? Most of the left-behind children say they miss their parents a lot, e 小题9:  during holidays. Maybe the government can set up special group activities for these children during holidays. Of course, the best thing for these families is to be together. As the song says, “If e 小题10:   gives their love, the world will be better.”

Best wishes to you!

Sincerely,

Mary
