Boys and girls,
What would you do if you were given much pocket money?How to use it is a big problem.Here is some advice.
First you can put it in a bank.This way,you can form the good habit of saving money,which will be helpful in your future life.Or you can buy some books with it to get your knowledge; it’s good for your study.You can also spend some of your pocket money on your favorite CDs,a football or basketball,stamps and so on; they can help you develop your interests.But please spend it playing computer games.
I think pocket money is quite useful if you make good use of it.
That’s all,thank you.再來點
