THE CAGE-BIRD AND THE BAT
A Singing—bird was confined in a cage which hung outside a window,and had a way of singing at night when all other birds were asleep.One night a Bat came and clung to the bars of the cage,and asked the Bird why she was silent by day and sang only at night.“I have a very good reason for doing SO,”said the Bird:“it was once when I was singing in the daytime that a fowler was attracted by my voice,and set his nets for me and caught me.Since then I have never sung except by night.”But the Bat replied,“It is no use your doing that now when you are a prisoner:if only you had done SO before you were caught,you might still have been free.”
Precautions are useless arter the event.
三天过去了,也没有使蚊子减少。 面对成群的蚊子,大家感到束手无策。野牛提议说:“我去请居住在石洞里的蝙蝠吧,也许它们能够消灭夜间飞舞的蚊子。” 孔雀听了说:“请那些黑不溜秋、模样古怪的.蝙蝠来灭蚊,它们能行吗?” 羚羊听了说:“蝙蝠眼睛高度近视,夜间难道能看见蚊子吗?” 野牛说:“你俩别先下结论,我去把蝙蝠请来试试不就知道啦!” 狮子大王说:“野牛,你快去请吧!” 野牛把蝙蝠家族请来了。它们成群地从山洞里飞出来,选择在蚊子出来活动的傍晚和清晨进行捕。在昏暗的低空里,蝙蝠们依靠发出的声音,用超声波定位认准目标,飞上飞下,时隐时现,追捕蚊子准确无误。
三天后,森林里的蚊子果然少了很多。狮子大王高兴地对蝙蝠家族说:“你们灭蚊有功,‘灭蚊冠军’的称号非你们莫属!” 孔雀和羚羊知道蝙蝠获奖,自觉羞愧。 寓意:对待任何事物都需要去了解情况。而不是武断地下结论。

今天,在老师的带领下我们学习了《蝙蝠和雷达》这篇课文。
这篇课文的主要内容是讲科学家从蝙蝠身上得到启示,经过多次试验研究,由此发明了雷达。你也许会问吧:蝙蝠和雷达可以说是“八竽子打不着”,它们怎么会有牵连呢?好了,我来告诉你吧,你在电视里或许看到过一些蝙蝠在夜晚飞出洞穴去寻找食物吧,可你见过它们碰到障碍物上吗?
没有吧,你知道这是怎么回事吗?原来,蝙蝠有一套可以在夜间安全飞行的“秘密武器”使它不会与障碍物相撞。科学家经过试验得知了这个答案,而且发现,蝙蝠夜间飞行并不是靠眼睛,而是靠它们的嘴巴和耳朵配合指挥路的。因为蝙蝠的嘴巴可以发出一种人类听不到的声音,叫超声波。这种超声波像波浪一样推到前方,超声波遇到障碍物又传回蝙蝠的耳朵里,蝙蝠便得知前方有障碍物,并绕道而行。所以蝙蝠能安全地在夜空飞行。 三眼看世界
从这篇课文中我明白了,大自然的'力量真伟大,它就像人类的好老师一样,无时无刻不在给我们启示。
蝙蝠喜欢群居,白天躲在阴暗的石洞里休息,夜晚才出来寻找食物。森林里的很多动物很少看见它们。
夏天来了,成群的蚊子夜间在林间飞来飞去,嗡嗡作响,干扰了动物们的日常生活。狮子大王下令:“如果谁在三天之内能使蚊子明显减少,将获得‘灭蚊冠军’的称号。”
燕子家族最先响应。它们全巢出动,在树木丛里搜寻捕,在空中飞追扑捉,使出全部本领。三天后,夜间蚊子还是很多。
蜻蜓也带领家族成员飞来了。它们眼观八方,左抓右捕,全力以赴捕捉蚊子。三天过去了,也没有使蚊子减少。
面对成群的蚊子,大家感到束手无策。野牛提议说:“我去请居住在石洞里的蝙蝠吧,也许它们能够消灭夜间飞舞的蚊子。”
孔雀听了说:“请那些黑不溜秋、模样古怪的蝙蝠来灭蚊,它们能行吗?”
羚羊听了说:“蝙蝠眼睛高度近视,夜间难道能看见蚊子吗?”
野牛说:“你俩别先下结论,我去把蝙蝠请来试试不就知道啦!”
狮子大王说:“野牛,你快去请吧!”
野牛把蝙蝠家族请来了。它们成群地从山洞里飞出来,选择在蚊子出来活动的傍晚和清晨进行捕。在昏暗的低空里,蝙蝠们依靠发出的声音,用超声波定位认准目标,飞上飞下,时隐时现,追捕蚊子准确无误。三天后,森林里的蚊子果然少了很多。狮子大王高兴地对蝙蝠家族说:“你们灭蚊有功,‘灭蚊冠军’的称号非你们莫属!”
孔雀和羚羊知道蝙蝠获奖,自觉羞愧。
故事寓意:对待任何事物都需要去了解情况。而不是武断地下结论。
