假如你是李華．校英文報Growing pains欄目專門解答中學(xué)生的煩惱問題．現(xiàn)欄目收到一封來信．請根據(jù)這封信的內(nèi)容寫一封回信．
Dear Editor，
I am really angry with my parents recently．Next Sunday is my birthday．My parents promised to buy a cell phone for me as my birthday present this year．But now when I ask about the birthday present they say they have changed their ideas，because they worry about my study if I get a new cell phone since the final exam is coming soon．They say a cell phone may take up too much of my time．I believe I am old enough to control myself，but they don't believe me．What's more，they broke their promise!

Dear Li Yan，
It's normal to have these feelings．

As a saying says，to be appreciated as a parents is quite unusual．It is quit sure that parents are willing to do their best to give us as possible as they can．We should understand the good intentions of parents．They must have been for your own good．As a high school student，our studies are important and very heavy．There are many advantages of mobile phone，checking dictionaries，listening to music，checking information and so on．But there is also a lot of harm，such as improper use，indeed affect the study and life．We should try our best to study and make great progress．
