寻找新的家园

寒假，我去了位于南半球的大堡礁，这里是世界上最大、最长的珊瑚礁群。坐在半潜水艇里，我看到了五彩缤纷、千姿百态的珊瑚，成群结队、大小不一的鱼儿欢快地在珊瑚群里穿梭，简直就是透明清澈的海中野生王国，真是太美了！||| 我突然想起了妈妈为什么会带我来看大堡礁，不禁有些伤感。据海洋学家预测，因全球气候变暖，二氧化碳排放造成的升温让珊瑚惨遭漂白甚至溶解，大堡礁的美丽珊瑚礁景色将于2050年永远消失，取而代之的只是大片水草。如果美丽的大自然奇迹真的会消失，那我们唯一的家园——地球，会如何呢？难道地球上的煤、天然气等资源也真的会被人类使用一空吗？难道地球终究会有一天不再适合人类居住吗？在蔚蓝的太平洋上，无数的疑问在我脑海里闪过，一个梦想越来越清晰地展现在我心中——寻找新的家园。||| 从小，我就非常崇拜杨利伟、翟志刚等宇航员，看着他们坐上“神舟”飞船，飞向无边无际的太空，我就梦想有一天，和他们一样，也能去太空看看。我不止一次地构想着一个画面：30年后的某一天，我登上光速的宇宙飞船，前往外太空，寻找适合人类居住的星球。经过努力，我找到并成功登上了那个星球，和同伴们一起制造出空气和大气层，和外星人交朋友，商量地球人的搬迁。之后，我回到地球，自豪地对全世界人民说：“我找到了新的家园。”||| 梦想很远，实现梦想的路却很近。我要锻炼好身体，才能经得住宇航员的魔鬼训练，才能在太空失重的环境中行走。尤其要保护好视力，太空可不欢迎近视眼。我要认真学习，学好每一门功课，抓紧一切课余时间更多地了解太空知识。我要把英语学得象母语一样流利，以便将来和太空工作站的外国人交流沟通。我要更多地培养自己的幽默感，未来见了外星人，跟他们谈天说笑。||| 我相信，只要我脚踏实地地走好梦想之路上的每一步，梦想就一定能成真。太空，等着我！新的家园，等着我！|||
