Dear Editor (编辑),

     After I finish my homework, I often go online and chat with my friends and play Internet games. But

my parents hate to see me playing games on the computer. Maybe they have heard too much news about

how QQ and Internet games harm (伤害) children. Once I went to a net bar (网吧) to play games after

school. But after that I told my parents that I was playing basketball at school. I said so because I didn't

want to make them unhappy. I feel bad about it. However, I need to rest for a while by playing computer

games after studying for a long time. I really want my parents to understand that. Do foreign parents do

the same to their children? Please help me.

                                                                                                                                      Yours,  

                                                                                                                                       Li Ping  

Dear Li Ping,

     I think it's not strange for parents to keep their children away from anything bad. Foreign parents will

do the same as your parents! They may not let their children watch TV for a long time, or like your

parents, they don't want their children to play computer games.

     Talk to your parents and be honest (诚实) to them, I think. Tell them what you are doing and why

you are doing so to make them understand you. It's never good to do things behind your parents' backs.

They aren't fools as you think sometimes! Our parents seem to know what is the best for us. Remember:

to be honest is the best way. 

     Good luck!

                                                                                                                                        Yours,  

                                                                                                                                         Zhang Yu
