养育下一代
如果家长是瞄准了将孩子培养成一个天才的话,他们往往会失败得一塌糊涂.根据一些前沿教育心理学专家表示,这些是那些富有野心的家长犯的严重错误之一.一般来说,孩子会只单单意识到家长的期待,并且会失败.家长不切实际的期望会给孩子造成巨大的不利影响.然而,如果家长对于孩子的作为的期待并不那么不切实际,而只是在一个理性的范围内有所抱负的话,孩子就很可能会在他所作的事情里变得很成功,尤其是家长很支持他们的孩子.
Michael Li 就非常的幸运.他异常热爱音乐,他母亲几乎不懂音乐,他父亲在一个大型管弦乐团里吹小号,家长为了支持他,带他去音乐会,给他安排私人钢琴、小提琴课程.尽管如此,如果Michael不愿意,他父亲绝不会强求Michael参加音乐竞赛.反观Michael的朋友Winston Chen就不那么走运了,尽管双亲都是成功的音乐家,他们给Winston设定的目标似乎太高了.
他们要求他们的孩子要跟他们一样的出色,于是乎他们给Winston安排进每一个举办的钢琴比赛,当他没有得奖的时候,家长就非常的不高兴.Winston的父亲跟他说：“当我在你这个年龄的时候,我会赢得每一场我参加的比赛.”Winston总是害怕会让家长失望,于是现在他就总是沉静不语、郁郁不欢.

　　When I was a naughty boy,may be because of the influence of the film."Xiao Bing Zhang Ga",my dream was to be a soldier just like Zhang Ga.I thought if I was a soldier,I should be able to swim,dive and climb trees as he did.It seemed to be very wonderful.So I began to learn swimming,diving and climbing trees.I practiced every day and finally I could do them well.But when I entered junior high school and had the military training.I suddenly found that being a soldier was very difficult and I wasn＇t strong enough to bear it .I had to give my dream up.
　　But I wasn＇t discouraged,and I had new aim,which was to be a postman,or rather to be a newspaper boy.As a newspaper boy.I could speed along streets on a bike and throw newspapers onto every porch.That＇s also very cool.So I started learning to ride a bicycle.After the everyday practice,I could go very fast by bicycle.But to my disappointment,the job which I wanted only existed in western counties not in China,because there was no porch in China.And Chinese postmen had to stuff very thick newspapers into very small mailboxes from very narrow entrances.The job was far from what I had expected.So once again my dream fell through.
　　Perhaps you have had the same experience as I and most of your dreams haven＇t come true yet.But I think it doesn＇t matter,because if you have a dream,you＇ll make many efforts to realize it.This course is really important.If I hadn＇t dreamt of being a soldier or a newspaper boy.I wouldn＇t have learned to swim,to dive,to climb trees or to ride a bicycle.Even if our dream can＇t come true,you＇ll learn much from the efforts you have made.So what I want to tell us is that dream helps us to grow up and teaches us how to control our lives .It is dream that gives us power and makes our lives colorful.（英语作文）
