在我们中国上下五千年,其中也不乏盛世,人民生活幸福指数可能高于现在,但是对于那时环境污染的记载却几乎没有。而在近一个世纪里,尤其是最近的几十年中,环境被严重破坏,到了触目惊心的地步,人类的生存条件日渐降低,许多的生物已经绝种,大量的物种濒临灭绝,为何?
“水可载舟、亦可覆舟”这是我国博大精深文化中的一句。我认为非常有道理。最近的一个世纪,科技的兴盛,创造了无数的前所未有,但同时也带来了前所未有的大破坏。科学技术的运用发明了更多的产品,也使人类的***更加膨胀,带来了战争,于是大量开发矿产,破坏地形地貌,破坏了生物链,最终也破坏了人类的生存条件。
在我国五六十年代,庄稼所用的肥料都是有机肥,用家畜的粪便或用河道里的於泥,腐烂的草,土地的特性得到保持,但在使用化肥农药后,产生了一系列的恶性循环,土地日益酸碱化,农作物也受此影响,而这种现象要大自然用几百年的时间才能减弱。另外,河道中的淤泥日益增多,破坏了生态环境,加上工业污水使鱼儿无法生存,前些年,太湖大面积的发生蓝藻,使无锡市民得不到饮用水,也是这方面的因素。
而工业的发展更加剧了破坏环境的进度,石油和煤炭的大量开采,大量的排放和尾气产生了地球温室效应,使得全球气候产生了变化,引发了许多的自然灾害,如此长久下去,人类迟早会毁灭在自己的手中。
幸好人们发现了这种变化,许多国家在发展工业的进程中也加强了保护环境的意识。德国是一个人造森林最多的国家,在破坏的同时绿化相同的面积,从而保持了总的\'生态环境。在我国,这种做法也在逐渐推广,运用科技力量,在发展中注重环保,但是只起到一部分的作用,同样,在太湖蓝藻事件中,许多的方法只起到了表面的作用,最后,放养了大量的鲢鱼去食用蓝藻,用生态平衡法则来解决根本问题。
近几年来,在我们农村,环保意识史无前例的加强了,建立了许多生态保护区,更多品种的生物回来了,在我家后面的河面上,多了一些不认识的水鸟,爷爷说四五十年没见到了,这让人感到欣慰。
所以,我们这一代人身上的使命更神圣了,责任更大了,我们要加强环保意识,提倡“低碳”生活,处处进行“节约”生活,从细节着手,保护好我们的家园,保护好大自然,保护好我们赖以生存的地球。
最主要的是里面还配有各式各样的餐厅,运动员们想吃什么只要轻轻一点按钮,可口的饭菜立刻就会呈现在眼前。让来自全世界各地的运动员都能吃好,睡好。在比赛中多得金牌。 假如我是科技奥运设计师,我会设计一种利用卫星导航系统和二氧化碳飞翔的汽车,这辆车每天都载着所有的运动员,在空中有序的飞翔,使运动员们每天都能快速及时地进入各个比赛场地专心致志地参加比赛。 假如我是科技奥运设计师,我会设计一种巨大的吸尘器,一有污染,吸尘器上的报警按钮就会接受到信号,工作人员在第一时间赶到,让北京的天空永远变得湛蓝,纯净。 假如我是科技奥运设计师,我会设计许多个像福娃一样可爱的小机器人,因为那时侯将有许许多多外国友人来北京。
黑皮肤的非洲人,蓝眼睛的欧洲人,金头发的美洲人……我要让这些机器人,带着五湖四海的游客,去了解一个有着悠久历史,灿烂文化,礼仪之邦,热情好客的文明古国。 假如我是科技奥运设计师,我会设计一种多功能太阳帽,这种太阳帽的形状与一般太阳帽相同,只是除了帽檐以外,其它地方都是双层。在两层中间有一张由纳米电脑控制的`过滤网,可以把阳光照射下来的热量转为冷气,从第二层的小洞向下排,让在炎热夏季来北京观看比赛的全世界观众戴上它都十分舒服。 假如我是科技奥运设计师,我会设计一种检测的新型仪器。
这种仪器外形十分新颖别致,椭圆形的外壳下面是一个微型电脑屏幕,外壳四周分布着十分精致的小按钮。当运动员比赛完后进行尿液检测时只要轻轻按一下调节心情钮,根据屏幕上变幻不同的颜色,可以准确无误的查出是否服用,让奥运会在公平,公正中进行。 啊!要是我的梦想能够实现,那该多好。
Every four years, people will look forward to the biggest sport game, the Olympic Games. This year, The Rio Olympics is coming soon, as the media much pay attention to report the progress, more problems of this big project have been revealed.
每四年,人们会期待最大的体育比赛,奥林匹克运动会。里约热内卢奥运会快到了,今年媒体非常关注并且报告了进展,然而更多项目的问题被揭露出来。
The biggest problem is the unfinished buildings. It is known to all that a city will be given the right to hold the Olympic Games at least 8 years ahead, so that the government will have enough time to prepare. But the day is so closed and some sports courts are still being built, how could this happen in such big event.
最大的问题是还没完成的建筑。众所周知,一个能够得到举办奥运会权力的城市会提前至少8年揭晓,这样,政府才会有足够的时间准备。但如今日子很临近,一些体育场地还在建,这种事在这样的事件怎么可以发生在这样重大的比赛前。
The second problem is the health. Rio is not the developed city, its health care must can’t compare with the developed contries. As its hot weather and other reason, some diseases are easily to spread. It has been reported that some athletes have dropped out of this coming event, for there exists a kind of virus which will make people sick badly.
第二个问题是健康。里约不是发达的城市,其卫生保健必定不能与发达国家进行比较。由于炎热的天气和其他原因,一些疾病很容易传播。据报道,一些运动员退出即将到来的比赛,因为这里有一种病毒会使人们病得很严重。
As the opening ceremony is so closed, the world is watching at Rio. Maybe it will surprise us.
开幕式是如此的接近,世界都在关注里约奥运会。也许它会给我们带来惊喜。
Given is a simple but thought-provoking remark: "it is unbelievable for people to believe what they should not believe: Internet rumors." Obviously, this saying can be naturally associated with the seriousness of rumors: if we intend to have a positive Internet environment, it is advisable to eliminate/refuse rumors.
In contemporary society, it has become a trend for individuals to surf the Internet for the information they need. Meanwhile, an increasing number of people find it rather difficult to distinguish the true news from rumors. Searching the Internet, we can notice a great many examples like this: false news, ads and pictures.Then, it is these rumors that lead the public to be cheated, confused and even panic. As a matter of fact, experts in large numbers have come to realize the importance of Internet honesty.
As a regular Internet surfer, I am convinced that it is of great necessity for government to punish rumor makers. Accordingly, we should educate, advocate and encourage our friends, classmates and acquaintances to refuse making and spreading rumors. Sparing no efforts to do so, we will witness a hopeful and promising future of Internet life.
Perhaps there is something you don't know how to doTTn the past, you might turn to a friend or a relative, attend a night class or go to the local library to find the answer. But at present a lot of websites are springing np to offer free practical advice on these subjects aod actually anything else you can imagine.
Why is online learning so popular among people? The answer is obvious: online learning is nuich more convenient. In the past, you perhaps had to spend pienp of lime learning m a night class or going to the library to look for relevant materials. However, now when you run into a problem, yotijust need to click the mouse, then a lot of related websites will appear in front of you*
However, not all the materials on the Internet are correct; sometimes they are false. Thus, if you want to lcam something from the Internet, you should make sure what you will leam is completely correct.
