卡通人物的世界与地球出现了裂痕，木叶村、鸣人、木卡西，还有神奇的宝贝—皮卡丘，娃娃种子，杰尼龟和小红龙等都来到了地球，此时的地球环境非常的差，大家都被地球的景色惊呆了。于是，大伙决定清理一下地球环境。

大家先是清理大海，这个时候的大海让大伙吃了一惊，海面上到处是漂浮着石油，海底里沉着大量的垃圾，整个海完全被深度污染了。鸣人原本想用自己创造的绝招—爆旋圆，可是威力不够，他最终与父亲联合使出了终极绝技—太极爆旋圆，一下子就把大海里所有垃圾和海水都卷到了太空。杰尼龟在无意间拥有了穿越地球和神奇宝贝的能力，它叫来了一大群水系的神奇宝贝，它当然也成为了这些神奇宝贝的司令。这些队伍里有海刺龙、宝石海星、海星星、吴波和玛丽萝莉这五员大将。随着杰尼龟的一声令下，所有的水系神奇宝贝一起使用水枪，用了整整三天三夜，才把大海重新注满了水。

大家再来清理陆地，陆地上有许多坚硬的像小山丘一样大的垃圾堆，木卡西使出千鸟和雷切，将垃圾堆切成了一小块一小块的，皮卡丘使用妙蛙的种子，将自己送上了天空，使出了自己最拿手的好戏，打雷加上十万伏的龙卷风，将所有的垃圾聚集在一起，再由其他的宝贝全部清理掉。

最后，大家来改变天空。这一次，杰尼龟叫来了一大群的吞噬兽，小红龙用喷射火焰让热气球飞起来，送吞噬兽上天，这些吞噬兽不停地吸入有毒的空气。另外，妙蛙的种子放出了花之舞，空气里又弥漫着花的香味。经过十天十夜的不停的工作，地球又恢复到原来的样子。

我想对全球人说一句话：“要保护好环境，因为我们只有一个地球。”

太阳召集太阳系里的星球开了一次紧急会议，主题是拯救地球。太阳看大家都到齐了，就清了清嗓子说：“星球们，我们的好姐妹地球已经危在旦夕了，医生说她血液里都是毒素，身体里的营养物质也快耗尽了，在这样下去，地球没几十年了。”月球说：“近几年，人类大量开采石油、矿石、木材等材料，又不保护环境，地球姐姐不生病才怪。”土星说：“在这样下去不是办法，我们一起拯救地球吧！”“好！”星球们纷纷答应。

星球们回去后，都听说了人类在寻找第二家园，于是纷纷约好，绝不当人类的第二家园，也纷纷扔掉了可能被人类利用的条件。比如：月球扔掉了氧气，土星扔掉了适宜的温度，水星扔掉了……终于，人类意识到了地球是人类唯一的家园，开展了保护地球行动。

300年后，太阳又召开一次会议，地球也参加了，她看起来美丽极了，碧绿的皮肤，干净的血液，更重要的是她变得健康了，月球说：“姐姐，看到你现在这么健康，我真为你高兴。”水星说：“姐姐，看到你现在那么漂亮，我都有点嫉妒了。”地球说：“谢谢你们大家为我牺牲了这么多，我现在健康了，还是要感谢你们大家，谢谢你们了。”太阳说：“星球们，经过这次行动，人类已经认识到地球的重要性，我宣布，此次拯救地球行动圆满成功。”

朋友们，地球母亲的病虽然好了，但还需要继续疗养，现在，让我们一起努力，把地球装扮成宇宙中最美丽的星球。

全球气温的升高导致大陆冰川、山岳冰川逐渐融化，海水总量增多。同时，海水温度也在升高，海水因膨胀而导致海平面上升。气温上升1摄氏度，海平面要升高10厘米，而全球3/4的大城市和占40%的人口都集中在离海岸不过60公里以内的地区。

让我一起来保护地球，让地球母亲恢复自己原来的容貌。只要我们多骑自行车、多种树、少用化学品……就可为地球母亲做出巨大的贡献。保护地球从我做起，从身边做起!

[大学英语作文考试常用句子

五年级丁韬

帕克是地球上最后一个人了，二十年前，地球中人类文明正处于高峰期，他是七百位人去太空搜索信息的其中之一，他们每隔二十五天向地球发送一次信息，了解地球情况。过了十八年，原先的七百人只剩下五人，同时，地球环境也在一步步恶化。

过了十九年，帕克进行最后一次信息通讯，“嗞—”一声声浑浊的声音传入帕克耳中，同时，“流浪者”号的飞船显示屏上显示了其余四人均以死亡（三位因疾病死亡，一位因没有成功通讯而自杀），帕克感到十分奇怪：“地球上为什么没有人与我通讯？到底发生了什么？”于是，他下令投影出地球的现状，“天啊！这……到底发生了什么？”确实，以往的蓝色星球，此时已是死气沉沉，毫无生命迹象……

帕克十分无奈：哎！人类又干了什么？让地球成了这副模样？

他立马启动十台核聚变发动机，全速前往地球一探究竟。

到了地球，只看到了一个视频，人们身上长满鳞片，似乎得了什么怪病。帕克马上意识到了这是环境恶化带来的灾难。帕克叹了一口气，用飞船上仅有的材料搭成了一座房子，他坐进黑暗的房子，与他结识的外星人进行谈话，希望他们可以复制出地球上生物的基因和资料，外星人果然是帕克的朋友，爽快地答应了。

这次谈话过后，帕克就坐在地上，看着这个死气沉沉的地球，他流泪了。

“咚咚咚”。一阵又一阵清晰的敲门声在狭小的房间中荡漾，帕克欣喜若狂，啊！地球最后的希望，你终于来了！帕克连蹦带跳地奔向门口，打开了门，一阵强烈的白光充满他的眼帘，帕克下意识捂住双眼，过了一会儿，白光消失，帕克放下双手，一个外星人站在门口：一个滑溜溜的身子，四根脚趾，六根手指，它将一大叠资料交给了帕克，告诉他地球环境的恶化全是因为人类多次进行核辐射的实验，并警告帕克以后不要让人类进行这类实验，否则它也无法挽救。帕克谢过外星人，立马将基因变成一个个生物。

一缕缕银发在风中飘动，帕克望着生机勃勃的地球。他笑了，一颗颗泪珠犹如一串珍珠掉落在地，这是幸福的泪，地球获得了最后一次的重生！

这天，宇宙中心医院来了一个不速之客——全身布满超级文明人类的地球。只见地球满脸愁容，拄着拐杖，一瘸一拐地进了挂号室。挂号医生天牛星忙上前问寒问暖：“地球老弟，五十万年前，你是那么健壮，现在你所哺育的人类发达了，你应该更健康！可你现在怎么啦？”“哎，一言难尽，”地球苦笑着，“人类是发达了，可我的身体却一天比一天衰弱。要知道发达和衰弱可是截然相反的哟！”

为了更快地弄清自己的病情，地球告别了天牛医生。

他来到眼科…不一会，他便迈着沉重的步子走了出来，痛苦地想着彗星医生的话语：…人类大量开办工厂…废气污染…保护伞被破坏…地球给蒙上一层近几公里的灰纱。难怪地球因此戴上了厚厚的近视眼镜——是有三万六千度。

接着地球来到了皮肤科。主治医生仙女星座为了更好地给地球会诊，还请来了大熊星座两位特级医师。并一道先查了地球以前的《特级生命星证书》：地球，37万岁，诞生在太阳系；鉴于地球身体强壮，全身除海洋蓝色外，大部分绿色，不愧是个生命的摇篮。特予以表彰，并发证书一份。

仙女星座看了一眼浑身疮疤的地球，难过地叹了口气，带着同情的心情开始工作。等到诊断完，医生们已是满头大汗了，他们又忙个不迭地开了份诊断书：地球主诉，周身疼痛难忍，绿色皮肤开始脱落，黄色皮肤出现并不断蔓延。医生诊断：地球大陆肤色确由绿转为黄绿，黄色地区的沙漠已不断并吞绿洲；海洋由纯蓝变为局部灰蓝，海洋中局部地区已不能适应生物生存所需。病因：人类为获得耕地，乱砍乱伐；人类科学日益发达，随之带来的却是各种污染，如化学污染、核污染等；大批工厂不注意保护水源，向河流、海洋排放大量未经处理的废水、废渣。

地球拿到诊断书后，已是快要哭了。

最后，地球来到内科，他哭丧着脸对内科医生北斗星说：“医生啊！我觉得西经13.5oc、北纬32oc处隐隐作痛，不知是何原因？”北斗星闻说，忙往那里看去，只见那儿烟雾甚是稠密，似乎有一股火药味。医生忙搬来一架宇宙级显微镜，透过烟雾，看明白了一切，告诉地球：“那是人类在自相残杀！炮弹哪，搅得天空更浑浊了。”听了这话，地球的脸更阴沉了。

经过一系列的会诊，地球异常烦恼，近似哀求地请医生治好他的病。可医生们却说：这的病，我们无能为力；人类是宇宙的主宰，你的病最终将由他们自己来治理。

保护环境吧，地球在哀求。

保护和平吧，地球在呼吁。

在人们心中，未来的地球应该是一被高科技覆盖的星球，那时的地球已经进入了信息时代。这是一个多么好的未来啊，但事实却与之正好相反。

一亿年后的地球能源已被人们消耗的所剩无几。地球地核开始衰弱，地球引力越来越小。生活在地球上的人们总觉得轻飘飘的，而且大陆板块也开始四分五裂。据专家推断，地球地核会在五十年后停止运转，随后后各种气体也将飘离地球，地表也会开始碎裂，最后地球将会爆炸，所有生物都会灭绝，人类也不例外。这一消息震惊全人类。一亿多年来，人类在几次物种大灭绝中都存活里下来。难道这次真的没有机会了？

当人们惊恐万分的时候，一位信息时代的领军人物塔图说道：“人类还有希望，只要我们运用科学的力量，让地核重新运转。地球就不会爆炸，人类就不会灭绝。”这一段话点然了全球几十亿人心中的希望之火，大家都决定要让“地球之心”重新“跳动”。

经过了一年的准备，一切工作到位，大家开始了浩大“救心”工程。首先，大家用超强功率的核能钻地机。从地表的各个位置开始向地核进军。地球地核的正常温度应在四千摄氏度左右，但当人们到达地核的时候，地核的温度却已降到了两千度，可见地核的衰弱速度有多快。

来到地核后，人们便马不停蹄的在地和周围建造了一个量子保护罩，这是为了在地核加热过程中，保护地核不受破坏。接着，载着人们来到地核的核能钻地机摇身一变，成了能量运输的中转站。它通过压缩和摩擦将能量的温度和密度提升到极致，然后注入到地核中，使地核的温度上升，从而达到地核升温的目的。当然，有时会有几台机器出现问题，不能正常工作。这时，就到量子重组机出马了。量子重组机可以把有问题的机器量子化，然后传送到地表的重组机里。地表的重组机再把机器重组，让工程师来维修，最后再传送到地核。

在地核，可以说时间不再是金钱，而是可贵的生命，每一个在地核工作的人都非常认真。终于功夫不负有心人，经历了三十六年的不懈努力，地核终于重新运转了。消息公布的这一天，全球上下，人们共庆成功。参与过这项工程的人留下了激动的泪水。这次的成功，会在人类历史上留下重重的一笔。它会让人们永远的记住：地球——人类唯一的家园。

导语：地球妈妈在流泪，我们人类做了太多伤害它的事情，让我们一起来拯救它吧!下面是yuwenmi小编为大家整理的优秀英语作文，欢迎阅读与借鉴，谢谢!

Let’s Do Something to Save Our Environment

It is recently reported that some rivers and lakes have dried up in South China. A lot of fishes died. The bottoms of the rivers and lakes have become grass land. The water is becoming less and less because of the bad weather.

So everyone should do something to save our environment. First， we should save every drop of water， such as turning off the taps after using it and recycling the water. For example， we can water the plants and clean the rest room with our used water. Second， we should save energy， such as less turning on the lights and turning off the lights when we leave;Do more walking， more bicycling and less driving and so on. Third， we should ask our government to control the pollution from the factories.

Let’s act now from everything to save our environment. Don’t let our tears be the last drop of water in the world!

【参考译文】

让我们做些事情来拯救我们的环境

这是最近报道，一些河流和湖泊已经干涸的中国南方地区。许多鱼死了。河流和湖泊的底部变成了草地。由于天气不好，水变得越来越少了。

所以每个人都应该做些事情来拯救我们的环境。首先，我们应该节约每一滴水，如使用后关闭水龙头和回收水。例如，我们可以用我们用过的水给植物浇水和打扫休息室。第二，我们应该节约能源，比如我们离开时少开灯和关灯;多走路，多骑车，少开车等等。第三，我们应该要求政府控制工厂的污染。

让我们从一切行动来拯救我们的环境。不要让我们的眼泪成为世界上最后一滴水!

Earth day is every year on April 22, is a worldwide environmental movement. The first earth day activities were rising in the 1970 s in the United States campus environmental movement, this activity towards the world from the United States in the 1990 s, became a worldwide festival of environmentalists and environmental protection awareness day, on this day people of different nationality in their different way to promote and practice the concept of environmental protection.

世界地球日即每年的4月22日，是一项世界性的环境保护运动。最早的地球日活动是1970年代于美国校园兴起的环保运动，1990年代这项活动从美国走向世界，成为全世界环保主义者的节日和环境保护宣传日，在这天不同国籍的人们以各自不同的方式宣传和实践环境保护的观念。

最初的地球日选择在春分节气，这一天在全世界的任何一个角落昼夜时长均相等，阳光可以同时照耀在南极点和北极点上，这代表了世界的平等，同时也象征着人类要抛开彼此间的争议和不同，和谐共存。传统上在很多国家都有庆祝春分节气的传统。早期联合国也在每年的春分举行世界地球日的活动。地球日当天表现

“地球日”这天，美国全国大约有1亿人把汽车放在家里不用，以防汽车排放出来的废气和其他有害的排放物散发到空气中去。在中国，当时的李鹏总理在4月21日通过电视发表了环境问题讲话，中央电视台还播放了“只有一个地球”的专题报道。从此，我国每年都进行“地球日”的纪念宣传活动。

2000年2月末，海斯接受中国的邀请，来中国参加了“中国2000年‘地球日’中国行动”启动仪式。

在20世纪90年代末，盖洛•尼尔森和布鲁司•安德森(太阳能建筑师、作家、新罕布什尔州“地球日”组织者)共同为把“地球日”办成一个年度性、高水准的活动，创办了“美国地球日”组织。“地球日”网页于1995年开通。1999年“美国地球日”组织更名为“地球日网络”，成为一个面向全世界、推动每年“地球日”国际活动的组织。2000年的“地球日”，又是由盖洛•尼尔森和丹尼斯•海斯领导，所不同的是，这次他们在1970年“地球日”的基础上，加入了全球性的公众运动，并充分利用了网络这一新兴的信息手段，把各国人民的智慧和热情都聚集在了一起。在盖洛•尼尔森、丹尼斯•海斯和其战友们的努力下，今天的“地球日”已真正成为全地球的节日，提醒着人类保护地球、善待地球。
