有个人听说了公孙龙,便前来求见,要求公孙龙收他做弟子。公孙龙见那人相貌平平,粗布衣帽,便问:“我不结交没有本领的人,不知你有什么本领。”
那人说:“大的本事我没有,只是我有一副好嗓门,我能喊出很大的声音,使离得很远的人也能听到。一般没有人能像我一样。”
公孙龙回头问他的弟子们:“你们中间有没有喊声很大的人?”
弟子们争相回答说:“我们都能喊大声。”说着还用眼斜瞟着那个前来求见的人,显出一种不屑的眼神。
那人说:“我喊出的大声,非常人可比。”
公孙龙很有兴趣地说:“那你们比试比试。”
于是弟子们推选了他们之中声音最大的一个做代表,与那人一起走到五百步开外的一座小丘背后,向公孙龙这边喊话。结果,除了那个人的声音外并不见弟子的半点声响。于是公孙龙把那人收留下来。可是,弟子们依然不免暗暗发笑,喊声大又算什么本领,喊声大派得上什么用场呢?老师是斯文人,难道要找个一天到晚替自己吵架、吼叫的人么?弟子们都不以为然。
过了不久,公孙龙到燕国去见燕王,他带着弟子们上路了。走了一段,不料碰到一条很宽的大河。可是河的这一边见不到船,远远望那河对岸,却停着一只小船,艄公蹲在船尾正无事可干。
公孙龙马上吩咐那个刚收留的大嗓门弟子去喊船。那弟子双手合成喇叭状,放开嗓子大喊一声:“喂……要船啦……”喊声亮如洪钟,直达对岸,那对岸船上的艄公站起身来,喊声的余音还在河两岸回响,以致慢慢传到很远很远的地方。
对岸那只船很快摇了过来,公孙龙一行人上了船,原先那些不以为然的弟子深深佩服老师及那位新来的朋友。
看起来,只要是本领,它总有用处,我们不应该排斥或看不起小本领,在关键时刻,小本领也能派上大用场。
在新课开始,黄老师用两张照片引发登山的话题,适时引入五岳的高度让学生比较,进而让学生产生学习新知识的需要。
心理学研究表明,当学习材料与学生的生活经验相联系时,学生对学习最感兴趣,会觉得内容亲切,易于接受与理解。当学生认出“登山”照片上的是华山时,一下子拉进了师生之间的距离;大昂学生猜出老师登上的是华山时,“华山论剑”的`第二张照片引来了学生会心一笑。出示这两张照片,既是对学生聪明才智的肯定,更是新课程理念下师生关系的具体呈现。
设计更为巧妙之处是,三轮游戏的设计,黄老师通过改变教学行为,让学生体验到数学学习原本并不是让人生畏、令人生厌的,而是其乐融融、美妙至极的一件乐事。那一次次欢呼雀跃的喊声,那一次次高谈阔论的言谈……都证明了孩子们学得很快乐。游戏、竞赛极大地调动起学生学习的积极性。更为厉害的是,黄老师,在本节课并没有停留在追求数学课表面的“热热闹闹”,为“游戏”而“游戏”上,而是追求“数学知识”与“游戏竞赛”的完美结合——有“游戏”扣人心弦的形式,更有“比较数大小发放”的“内化”。如,本节课非常注重让学生在比赛过程当中“有感而发”——每场比赛完,让学生记下比赛“结果”,进行“数学”的思考,组织学生交流“比较数大小”的方法和体会。学生的“感受”恰恰是“比较数的大小方法”的“内化”。数学源于生活,又高于生活,游戏是为了更高效地、生动活泼地让学生“掌握”和“内化”数学知识。这些都需要教师的智慧来激活学生灵动的思考。本节课当中,黄老师是教学活动的组织者,认知冲突的“制造者”,课堂气氛的“调节者”,学生思维的“启发者”。
Take your time
For thousands of years, animals have trodden a slow path, their spirits together with the body. But our human being's transportation is too fast. The body moves but the soul is left behind. We try to free ourselves in convenience, but we only imprison the soul. Since we invented how to count hours, we do everything to short the time, short the deadline. But the time saved can't be shorten. Nowadays, we spend lots of time staying in front of a TV just changing the channels, while we have no time to talk with a good friend or play with our family. We have plenty of time to search old news on the internet, while we hardly think about our life. In the end, the only thing apparent is our loneliness.
Take your time, please. Try to follow the natural steps and have your own clock. Try to share your time with everybody you love, share your mind, your happiness and sadness. Try to read the world we live in, do not only catch a quick glimpse at the society.Someday, when we know how to spend every second in our life, we can then live our own life.
孙悟空把水帘洞的三分之一给了唐三藏,十八分之五给了自己,九分之二给了八戒,剩下的十八分之三给了沙和尚。
猪八戒听了很不服气,觉得大师兄分得不公平,气冲冲地向师傅告状:“师傅,凭什么猴哥自己得到的地方最大,我的比沙师弟还小,这不明摆着欺负人吗?我们小一点也就算了,分给您的居然是最小的,太不像话了!您得好好教训教训他。”
孙悟空听了猪八戒的话,气急败坏:“八戒,你不要口喷人,我给的`师傅的最大!”
“你骗三岁小孩啊,师傅的才三分之一,而你的却有十八分之五。无论是分母还是分子,你的数字都比师傅大!”八戒很不服气地说。
听了八戒的话,唐三藏和沙和尚都哈哈大笑起来。唐三藏敲了敲猪八戒的头说:“八戒呀,分数大小比较,可不能光看数字的大小,你好好想想,把我们四个人的分数排排队,到底谁的大?”这下可把八戒难住了,他抓耳挠腮,急得团团转转,一时半会答不上来。
沙和尚站了出来:“二师兄,还是我来吧。比较分数大小,不能独立地看分子或者分母,比较分数的大小应该先通分,化成同分母分数,在分母相同的情况下,再根据分子大小来判断这些分数的大小。你根据分数的基本性质,把这些分数的分母都化成18,你会发现三分之一就是十八分之六,九分之二是十八分之四,这下你知道谁的房间大了吧!”
猪八戒不好意思地点点头地说:“我明白了,原来师傅住的最大,大师兄第二,我第三,沙师弟最小啊!”
孙悟空走到猪八戒面前,拍拍他的肩膀说:“以后遇到问题,可不要不动脑筋轻易下结论,学学人家沙师弟,少吃一些少睡一点,多腾出时间来来学习学习!”
Time flies like an arrow before we realize it .It is known that nothing is more precious than time. The good old proverb "time is money" reminds us that time is valuable. When time goes by, it will never return. However, it is a pity that some people don't make full use of their time .They spend a lot of time in sleeping, chatting playing computer games or other unmeaning matters. . They don't realize that wasting time is actually equal to killing themselves. They always regret not having made great achievements. One of the reasons may be they do not make good use of time. Therefore, in order to be successful, they should first get into the habit of being on time. It’s a sign of cherishing time. Don't put off what can be done today until tomorrow. Being lazy will eventually lead to failure. Don't wait, because you don't know how long it will take when you put off your plan.
The more we are aware of the significance of this famous saying, the more benefits we will get in study or job.
