假定你是某中学学生李华。最近，你班同学正在参加一个讨论会。本次讨论的话题是：父母的收入有没有必要让孩子知道？请根据下表所列情况给某报社写一封信，客观地介绍一下讨论的情况。

　　Dear editor，I'm writing to tell you about the discussion we recently had about whether we should know our parents' income.We do have different opinions on this matter. About 70% of the students think we should know our parents' income for the following reasons. First， it will help us understand how hard our parents have to work after we know their income， no matter how much they earn. Second， we will study harder and will not waste money any more. Furthermore， we may also learn to share our parents' trouble.However， about 30% of my classmates hold the opinion that it is unnecessary to let the children know how much their parents earn. Their reasons are as follows. For one thing， if they know their parents have enough money to support the family， they will not study hard. For another， if they do know， they will not worry about the future， especially when they know their parents have a relatively high income， the children will easily form a wasteful habit.YoursLi Hua
