“5.4.3.2.1!起飞!我们一行10人,8人是机器人。光速前进。所以,我们很快飞到了木星和火星之间的小行星带。据说太阳系的99%的小行星聚集在那儿。以前曾经有一架宇宙飞船坠毁在那儿,幸好是自动驾驶的飞船。才没有人伤亡,所以我启动了万能保护罩。
30分钟后,我们飞到了可能撞击地球的B(96小行星。它的`直径超过15公里,属于危险星球。如果它和地球相撞的话,等于1000000000颗核弹在爆炸,足以世界夷为平地。
“打开反向引力系统,我们要着陆了。”副机长说,A.B.C.D.E,你们驾驶AC钻地机,钻进小行星的中心,投放10枚核弹。马上和飞船会合。能做到吗?”
“能!”机器人们说。
飞船顺利地着陆了。
飞船刚着陆,钻地机马上开出飞船,向小行星的核心钻去。放了核弹。马上冲出来,与飞船会合。以音速15倍飞离小行星,“轰”的一声。小行星被炸得粉身粹骨。
“太好了,我们的任务完成了!”大家欢呼起来。
将来,我一定要当一名宇航员。保护地球不受陨星的攻击。
环境卫生是我们赖以生存的源泉,一但我们对它造成伤害,我们就无法生存。所以它就如我们的生命一样珍贵,因此只有保护环境才能保护我们自己。一天,我在校园走了一圈,发现校园里的垃圾还真不少,塑料袋,碎纸,雪糕纸……这引起我们反思——
我们天天都是生活在大自然中。生活在这美好的一切当中。地球妈妈慷慨的为我们提供各种无限而又有限的资源,让我们“丰衣足食”,而人类不但不知足,反而还破坏地球母亲。随着时代的变化,人们的要求也越来越高,他们把一棵棵大树砍下做成木船、一次性筷子等一切对人类有利的东西,而这些在人类的眼里总是一闪而过,对于大自然是多么大的破坏。
特别是5.12四川大地震,无论是我们国家,还是对我们人民造成多么大的伤害。多少人无家可归,多少孩子失去亲人。这难道不是我们人类自己酿造的苦果吗?人们还没有意识到自己所播种的灾难时,大自然已愤然回击。海洋与大气向人类发出了警告。全球不论哪一个海域,不管它与工农业活动区有多么遥远,从北极冰岛到南极大陆,到处都不同程度的监测到有害物质,唉!我以前喜欢的海洋到哪里去了?绿如蓝,成记忆了吗?
虽然,现在人们处处在宣传环保,呼吁绿色,但这样仍然没有阻止破坏者的脚步,一棵棵大树仍在倒下,沙漠的面积仍在扩大。
就是现在架起捕鸟网;饭店还在用一次性的筷子;人们还在抽地下水,除了各大超市外还有很多小商贩在用一次性塑料带,这些会造成多少白色垃圾。
现在已经是21世纪我们要保护我们赖以生存的地球,不要用一次性筷子和一次性塑料袋。少做一次私家车减少空气污染。我呼吁:保护我们的家园;保护环境人人有责;保护环境从我做起,从现在做起!
Giant Panda is our national treasure, the state can be said for the protection of giant pandas put a lot of human and material resources giant now has been the world's people the protection and care, which is a good thing, of course, the Tibetan antelope as the country's animal protection , The National People have been recognized, however, this tiger? The poor will be extinct Siberian tiger who is going to have a genuine concern and care a little bit?
According to statistics, the Siberian tiger left at present, less than 20, still such a small number of these survive, has had imagined. Two years ago, in the mountains of Huanren, Liaoning found to be a man to die under the presentation of the Siberian tiger, from this we can see that the above countries and the people of the importance we attach to it, this first Manchurian tiger is actually how the dead do not Conclusion, and the other is only from the northeast where hu came to the place where the wonder and the third is the matter did not rise to the national media in particular. This really puzzled the other person you! Is it really the other tiger who fear love is not worth it, it really fate of the Siberian tiger so?
Towering mountains should not unique to human beings, should not have dense forest unique to human beings, rivers clear this should not be unique to human beings, the Siberian tiger survival of this nature should not be unique to human beings. Siberian tiger to the left of a piece of heaven and earth to survive it, the High IQ is the human species, there are still ways to leave that piece of local survival, and the tiger have to leave that piece of the local dead; you save tigers, is the human population control, engage in Family planning, and the Siberian tiger is scarce Rending it! Now we can hear the cries of tigers in the future even the Siberian tiger can be heard the cries.
