    《人類未解之謎》讀后感

    時間:2016-07-22來源:小學初中作文網點擊:作文字數:1200字

      快到國慶長假了,媽媽給我買了本《人類未解之謎》。我高興地接過這本書,仔細打量這本封面以綠色為主底色的書。封面上幾幅遠古時代的小插畫為點綴,給這本書增添幾分神秘感,而白色鑲銀邊的“人類未解之謎”幾個醒目的字則告訴我是本科普書。我簡直愛不釋手,立刻就開始看了起來。這本書分為五個章節,分別是:科學與自然,歷史懸案,古跡與寶藏,奇異的現象,動物植物。自然科學,宇宙奧秘,讓我覺得地球真小,小到只是宇宙中的一顆塵埃;古跡寶藏和動物又讓我覺得地球真大,大到我們周圍的動植物都是那么的陌生,更有很多奇異現象無法解釋。

      我幻想著如果宇宙只有幾億光年大小,年紀大約只有五億年,還不到像地球上的我們小學生年紀,這樣,科學家就可以很快了解宇宙的奧秘;我也想像著喜馬拉雅的“雪人”和罕見的“蜥蜴人”也是人類進化的分支,并且是我們人類的好朋友;我還想象著很多奇怪的有毒植物,如今已經是我們人類攻克各類頑疾的良藥;我不知道什么時候已經是一名科學家了,正在破解人類未解之迷……….爸爸問我,看了《人類未解之謎》之后又有什么感想呀?我說,我想當一名科學家,我就知道一切秘密了。爸爸又說,那你就要好好學習了,這樣才有可能當上科學家。但是現在不當科學家也有更重要的事情要做呢,什么事情呢?我問。爸爸說,現在環保更重要,我們平時做的點點滴滴的小事,都可以對環保做出貢獻。

      我想,的確是這樣的,現在到處都是污染,很難看到爸爸說過的河水清澈見底,在河邊洗腳,小魚都來咬腳丫。我甚至都不愿意靠近水塘,因為水已經發黑發臭,成了蚊蟲和病菌的樂園。想到這里,我不禁害怕起來了;這樣下去,還沒等我長大,我們的居住環境就不適合我們人類生存了,還談什么做科學家呀。是該采取點非“科學”的方法來幫助改善環境了。我要向家人親戚和所有同學要求;不要亂丟垃圾,垃圾要分類(尤其是電池要單獨處理,據說一粒紐扣電池就能污染一個人一生的用水);用水要節約,洗衣的水可以有來沖洗馬桶,淘米洗菜的水可以用來澆花等等;要物盡其用,如廢舊牙刷可以用來做小刷子用,用舊的毛巾當擦地布等。還有很多不需什么‘‘科學’’就可以做好的事情,如;多種一棵樹,不浪費一張紙;多走路,少打(開)車,等等,希望同學們要多想想多做做。至于汽車尾氣的排放,工廠污染的處理等,這些都要交給科學家們去處理,我們大家要各司其責,共同愛護我們的家園------地球。有誰不喜歡綠樹成蔭,鳥語花香,山清水秀,藍天白云,空氣清新,滿眼皆綠的環境呢?

      我把我的想法和爸爸說了,爸爸說我的想法很好。同學們,你們覺得怎么樣呢?肯定是贊同的吧。那就讓我們共同保護我們的家園,破譯宇宙的奧秘吧!
