      闹钟与角 作文800字

      时间:2017-07-23 17:03 文章来源:网络整理 点击次数:

        我的床头有一只精美绝伦的小闹钟,是一只可爱的鹦鹉,眼睛随着秒针骨碌骨碌地转,显得是非俏皮。我之所以如此钟爱于它,不仅是因为他每天按时叫我起床,而且它还教会我许多数学知识。

        一天,我午睡刚醒,妈妈轻轻地打开门,向我走来。她注视着闹钟几秒钟,似乎想到了什么。然后,她指着我心爱的闹钟,突然发难:“你知道时针每分钟走几度吗?”“闹钟与角有什么破关系?鬼才知道!”我觉得妈妈问得莫名其妙,支吾着,又不甘心认输,便开始叽里咕噜地埋怨妈妈:“太难了,没学过,闹钟与角两个毫不相干的概念能撞出什么火花?妈妈你一定搞错了!”妈妈的神情有点不屑,转身离开了。她的举动让我多少还是有一点难过。

        我凝视着鹦鹉闹钟,开始苦思冥想,闹钟和角到底有什么关系呢?一分钟、两分钟,我毫无头绪,五分钟、十分钟过去了,我的迷惑有增无减。我绞尽脑汁,左思右想,仍然没有发现其中隐藏的秘密。过了 很久,我觉得答案似乎就在眼皮底下,可我怎么也找不到,我几乎彻底绝望了,不过心里一直在安慰自己:“数学界里许多难点我都能解决,这微不足道的角,偏偏让我大伤脑筋。”转念又想:“不可以遇到困难就那么容易放弃,再想想看,说不定下一秒就豁然开朗了。”我一边想一边给自己打气: “你一定可以的,加油!用你那双火眼金睛去发现其中的奥妙,用你的大脑去努力思考,其实答案很简单,只要你有一双慧眼,善于发现它。”

        “ 啊,我终于发现了!”我欣喜若狂,大声宣布:“时针转一圈是12小时,一圈不就是360度,360度除以12小时等于每小时30度,1小时等于60分钟,时针每分钟转0.5度!”我激动得不知如何是好,心里却想:“很久没有遇到这样的挑战了!差点儿把我弄糊涂了,这么简单的问题居然把我这个数学天才难倒了。”

        妈妈望着我得意忘形的样子笑而不语。我高兴得在床上乱蹦乱跳。过了一会,我好像又变了个人,立马开始了埋怨模式,因为妈妈又问我:“那分针每分钟走多少度呢?”这一次没能难倒我,我用刚才的方法顺利解决了。妈妈不由自主冲我竖起大拇指,而我则佩服妈妈能把我们学过的知识放在生活中去,用这样的方式来考验我,让我领略到数学无穷的魅力。

        此后,我也找到许多生活中的数学,比如:买东西,数硬币……我终究还解决了两道难题,妈妈也甘拜下风,表扬我能够学以致用。我一见妈妈认输,便在她面前手舞足蹈,在床上跳来跳去,高兴得合不拢嘴。

        数学,就像一座高峰,直插云霄。刚刚开始攀登时,感觉很轻松,但我们爬得越高,山峰就变得越陡峭,让人感到恐惧。只有真正喜欢数学的人才会有勇气继续攀登下去,才能领略到数学王国无限的风光。我们一定要好好学习,用心去发现生活中的数学奥秘,将来造福社会。
