动物灭绝英语作文【一】
在两亿年前，曾经有着一群霸主驰骋在地球上，它们形态各异，习性也各不相同，它们就是人类以前，地球的主人——恐龙。但不知为什么，恐龙这一词竟奇迹般得从历史的篇章里消失了。对此，人们众说纷云，陨石撞击，食物中毒……这一个又一个猜测充满了根据，却始终徘徊在“恐龙灭绝”这一框框里。虽然人们都在猜测着恐龙是如何灭绝的，但我却固执地认为恐龙并没有灭绝，只是进化成了我们身边的生物。 或许有人会说这是无稽之谈，恐龙早就灭绝了。但我们谁又真正看到过恐龙灭绝呢？所以我们不能否定恐龙进化后的存在。也许它和猿人一样虽然原样不在了，但它们却在进化中进化出了新的.种类。就像三角龙与犀牛一样，三角龙也许在时代的变迁与生活的需要中逐渐将头上两根如利剑般锋利的尖角退化了，容貌与体形也改变了，就成了如今的犀牛。
在自身或外界因素的影响下，一切生物都有变异的可能，包括恐龙和人。谁能肯定以前的梁龙不是现今的大象或长颈鹿？以前的鱼龙不是现今的海豚……大千世界，无奇不有，世界是奇妙的，生物本身更是奥妙无穷，我们不能轻易否定一个理论，也不能随意信服某一事物。
恐龙灭绝猜测众多，无可否认，恐龙时代肯定发生过自然灾害，但并不表明恐龙就此绝种。就算是自然力量让恐龙灭绝了，但为什么比恐龙微小、脆弱的生命都存活了下来呢？智慧？还是“武装”？
与其说恐龙灭绝是因为陨石撞击等，我宁愿固执地认为恐龙并没有绝种，只是进化成了另一种类。恐龙永远是个永恒的话题，在没有任何记录的情况下，就要靠人类自己去想象，去开拓。终有一天，恐龙之谜会被揭开，被公众于世，也许那时，人类已进化成了另一种新的种类！

大家好！我是一个快乐的洪水，在以前的生活中我无处不在，可到了3002年，我们洪水却变得寸步难行！
在3002年，人类发明了许多治我们洪水的工具，比如——自动防护器、变形口袋，但最让我头痛的就是变形口袋了。
“哗，哗哗！”正当我和流沙哥哥玩的正欢的\'时候，突然，一陈“葱葱”的声音响起，刚才还是一片光秃秃的沙地，转眼间变成了一片茂密的树林。它们如同一大群英勇的战士站在我和流沙哥哥的面前，“这可怎么办？洪水妹妹，你看！头上的口袋……袋正在……在冒出一棵棵粗壮的树，我们快点逃吧！”说完，流沙哥哥拉起我就要跑，可是眼前又冒出一堵厚实大墙，原本我以为很容易突破，谁知，不管我们俩怎么使劲冲，但它依旧稳如泰山，就在这危急时刻，我想出了一个“狠心计”，于是，我跟流沙哥哥咬了咬耳呆，便行动起来。
“哗！哗啦！”我们一起往那堵墙上“跳”去，忽然，出现了一个人影：“哈哈，瞧你们这疲倦的样子，要不如——装进我的口袋里吧！”你们的“鲤鱼跳龙门”不管用了！“怎么办？我着急地想，一看，“呀！流沙哥哥怎么被那……那堵墙吸收了！”我被吓得眼珠子都快掉下来了，“接招！坏蛋！”刚才的大口袋竟变成了一个大水罐！一股强烈的引力把我吸进去。接着，又有一群我的姐妹们也被吸了进去，她们遍体鳞伤、惨不忍睹。“咚！”一阵响声传出来，那个人按下了“转害为宝”的按扭，一阵刺痛之后，我便失去了一切知觉……
就这样，人类又以同样的方法把别的洪水也给转害为宝，就这样，我们洪水家族就从此灭绝了。
