求一篇获取信息的途径的英语作文

Life on earth depends on waterand there is no substitute for it. The current assumption is that our basic needs for water-whether for drinking agriculture industry or the raising of fish--will always have to be met. Given that premise there are two basic routes we can go. more equitable access to water or more drastic engineering solutions.Looking at the engineering solution first a lot of my research concentrates on what happens to wetlands when you build dams in river basins particularly in Africa. The ecology of such areas is almost entirely driven by the seasonal change of the river--the pulse of the water. And the fact is that if you build a dam you generally wreck the downstream ecology. In the past such problems have been hidden by a lack of information. But in the next century governments will have no excuse for their blissful ignorance.The engineers ability to control water flows has created new kinds of unpredictability too. "Dams in Africa have meant fewer fish less grazing and less floodplain agriculture--none of which were anticipated. And their average economic life is assumed to be thirty years. Dams don"t exist for ever but what will replace them is not clear.The key issue in any discussion of water is money. To talk about a water crisis hides intractable problems such as poverty.Consider the problems of water supply in Mexico City or Delhi. If you" re rich you drink mineral water and may even have a swimming-pool--yet millions in such cities can"t get safe drinking water. People talk about the coming water crisis. I believe we have one now. It is a water crisis for the poor. 地球上的生命依赖于水,而且水是无法替代的。 目前人们的假设是,不管是饮用水还是农业、工业、渔业用水,我们对水的基本需要能够得到满足。在这一前提下,我们有两条基本道路可走:更合理地利用水资源或建立更多大型的水利工程。先来看看水利工程问题。我的大量研究的焦点在于如果你在河谷(尤其是非洲河谷)建立大坝,这会对湿地产生什么影响。该地区的生态几乎完全受控于河流的季节性变化——河水的涨落。事实上,如果你在上游建了水坝,通常会破坏下游的生态环境。过去,这类问题由于信息匮乏而鲜为人知。但在下个世纪,政府就不能为自己的盲目乐观找借口了。 工程师控制水流的能力产生了新的不可预知的结果。在非洲建水坝意味着渔业减产,草场减产,洪水泛滥区农业产量下降,所有这些都是事先未预料到的。而我们假定水坝的平均经济效益的寿命为30年,但水坝不会永远存在,我们还不知什么可以替代它。有关水的讨论的关键在于钱。谈论水危机掩饰了诸如贫穷这样棘手的问题。考虑一下墨西哥城或德里的水供应问题。如果你富有,你可以喝矿泉水,甚至于可以拥有一个游泳池——而这些城市数以百万计的居民却喝不上安全的饮用水。人们讨论着即将到来的水危机。我想我们现在已经有水危机了,这是一场穷人的水危机。

曲院风荷 及 三潭影月 英文介绍小作文

Three Pools Mirroring the Moon--三潭映月The largest of the three artificial islands on West Lake, the isle covers an area of 7000 square meters. The island with its inside lake is crisscrossed with many zigzagging bridges; a causeway that spans from west to east; the heavenly lights and clouds reflections in the glass-like water can been seen together with flowers in blossom. Trees stand here and there, birds and fish enjoy themselves in different spaces. Pavilions vanish into nothingness at a distance; bridges allow tourists to view the scenery from different angles with the wonderful result of a different scene for each step. Breeze-ruffled Lotus at Quyuan Garden 曲院风荷Breeze – ruffled Lotus at Quyuan Garden which features in lotus ranks the 2nd of Top Ten View just after Spring Dawn at Su Causeway. In Southern Song Dynasty, Quyuan Courtyard was an official vinery which located on the bank of the West Lake beside the Hongcun Bridge on the Linyin Road where many lotus were planted. In summer breezes, the air was scented with delicate fragrance of lotus intermingled with the tasteful bouquet of wine. However, the courtyard was very much neglected and the nearby lake silted up. It became a small garden with a small pavilion, a veranda and a few lotus flowers planted in the water in front.

Saving Water 为题的英语作文,300单词以上。

The world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earth"s surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.

Civil and Environmental Engineering 专业在美国就业有哪些出路

"土木工程,就是Civil Engineering,在美国的学科设置里可以细分为不少专业,其实Civil算是对这些专业的一个统称,里面会包括Structural, Transportation, Earthquake Resistance, Environmental, Water Resources, Geo-engineering, Management, 中国学生比较常申请的专业就这些,毕竟也是和国内的本科学科设置有对应的,下面就这些专业说一下在东海岸的就业形势。Structural Engineering的就业总得来说还可以。一般Master毕业后找到EIT (Engineer in Training)的概率还是挺大的,之后的趋势就是可以进一些Engineering Consultant, Engineering Designing性质的公司,做的工作无非是CAD加各种受力分析软件的熟练操作。但是结构在东海岸的薪水确实不高,一般的公司在学生转正之后的pay大概能给到3000-5000每月,这个还是Master能拿到的,还不是本科生。Transportation Engineering, 国内是一直流传着金桥银路铜房子的说法(现在可能成了金隧银桥),但是在美国,毕竟基础设施比较发达,也许这方面有饱和的迹象。但是Highway Engineering和Pavement Design方面也还不错,可能跟美国的高速公路比较发达有关吧。Earthquake Resistance, 抗震专业,学这个的Master建议做好读PhD的准备。Master 的就业不太理想,可以参考结构的就业。Environmental Engineering 和Water Resources Engineering, 这两个专业涵盖的面,和涉及到的行业非常广泛。一般来讲,工作内容涉及到Water Treatment,Drainage Design,Water Supply System, Irrigation等等。这个专业的Master毕业后建议多尝试一些行业,从这个角度讲,机会还是挺多的。尤其是当前美国页岩气的开采如此盛行,hydrofracking 和后期的重金属污水的处理,给Environmental的学生带来了不少机会。Geo-engineering,其实理论上讲,这个专业是地理或者地信大类下面的,就是凡是学生在Civil系的选课表里看到的“Geo”打头的课程,一般都是他们需要学习的(比如Geomorphology, Geomechanics, Geophysics等)。Geo-engineering其实是和Geo-science相对应的,非常类似于国内的工程地质,岩土工程。在东海岸的就业并不太乐观,但是这个专业在中西部的形势确实还不错,因为身边确实有这个专业然后跑到中部就业的同学,而且目前看虽然工作环境不是特别好,但日子还是有滋有味。Management, 工程管理。很多时候这个专业是开在学校的商学院下面(School of Management), 所以至于这个专业的就业,如果对工程方面的Technical Skill有非常强的emphasis的话,在土木行业里找工作还是有希望的。如果偏管理的话,就可以参考管理类专业的就业了。最后提一下在美国的新能源专业,有些时候也会划到Civil系下面,这个专业目前来看在大多数学校体系还不够成熟,所以Master就业之后的去向也略显迷茫。不过太阳能和风能在美国的现状还是不错的,虽然美帝的光伏产业一直不给力,但由于政府的补贴和广大消费者的环保意识,其实这个专业的就业形势还比较理想,中西部,尤其是加州,要好于东部。 "

司马光砸缸的故事用英语写下来,词数在120-15

Sima Guang TankSima Guang is a famous politician and writer in the Northern Song Dynasty. When he was young, one day he went to hide and seek with his buddies in the garden. One of the children covered their eyes with their hands, and other small partners quickly hid themselves. Some were hidden in the trees, some were hidden in the rockery, and some hid in the flowers. When everyone is hidden, the blindfolded partner begins to look for everyone.The blindfolded child carefully touched left and touched right. Everyone held their breath and was afraid to be discovered. Suddenly he "popped" and then he heard someone shouting, "Help!" The buddies all ran out to see what was happening. It turned out that there was a large water tank filled with water on the rockery. The little partner who climbed onto the rockery accidentally slipped into the water tank.The water tank is very large. Sima Guang and his companions cannot reach the water tank mouth at all. They can hear the help of life but cannot pull out the little partner who fell into the tank. Other small partners were scared away. Some ran while shouting for adults, while others ran while crying. Sima Guang was not terrified. He rushed out of wisdom and picked up a stone around the rockery and slid it toward the water tank. Because of his small strength, Sima Guang even squatted a few times. He only heard a click and the water tank was opened to a big hole. The water flowed out through the hole and the water flowed out. The younger partner was saved.The children, Sima Guang was very valuable when he encountered urgent matters and was able to calm down and find a solution to the problem. Sometimes we are not unable to solve the problem, but because of horror I do not know how to do it, so it is very important to keep calm in my mind.

被动一般式 doing being done完成式 having done having been done完成进行式 having been doing 无动名词仍保留有动词的特征,可以和自己的逻辑主语、宾语和状语等构成动名词短语。动名词具有名词的功能,在句中可以充当主语、宾语、表语、定语等成分。ue003二、动名词的时态和语态形式ue0041.动名词 的时态形式ue004①一般式ue004动名词的一般式表示动作或状态与谓语动词的动作同时发生,或者表示一种无时间性限制的经常性、习惯性的动作或状态。ue004He enjoys writing letters in English.ue004他喜欢用英语写信。ue004Many young people like playing football.ue004许多年轻人喜欢踢足球。ue004②完成式ue004动名词的完成式表示动作或状态先于谓语动词的动作或状态,如:ue004They regret having been unab le to help you.ue004他们为没能帮上你的忙而遗憾。ue004After having written the letter,he went to post it.ue004他写完信,就去寄它了。ue004She regretted having missed the film.ue004她后悔没有看到那部电影。ue004③完成进行式ue004动名词的完成进行时表示动作发生于谓语动作之前,并一直持续到谓语动词的动作发生之时,或继续。如:ue004Forgive me for my having been interrupting you so much.ue004原谅我打扰你这么久。2.动名词的被动式ue004当动名词的逻辑主语是动名词动作的承受者时,用被动式。如:ue004He climbed through the window without being seen.ue004他从窗口爬进去,没有被人发现。ue004She needs to work without being disturbed (=without people disturb her).ue004她要在无人干扰的情况下才能工作。ue004动名词的被动语态分成一般式和完成式两种。如:ue004The railway is in the process of being constructed.ue004铁路在兴建中。ue004After having kept a prisoner in the Bastille for many years,Dr Manette had recently been set free.ue004曼奈特医生被关在巴士底监狱许多年后,最近获释。ue004特别提示:-ing形式的主动形式表示被动意义ue004在want,need,deserve,require 等动词后,总是用-ing形式的主动形式表示被动意义,相当于“to be+过去分词”。如:ue004My watch needs repairing (= to be repaired ).ue004我的手表需要修理。ue004[来源:Z§xx§k.Com]The house wants cleaning.这房屋需要打扫。ue004在worth这个形容词后情形也是这样。如:ue004The film is worth seeing.这部影片值得一看。ue004The place is worth visiting.那个地方值得一游。ue004三、动名词的否定式ue004动名词的否定式通常是在动名词前加否定词not。例如:ue004I apologize for my not having kept promise.ue004我没能遵守诺言,十分抱歉。ue004I regret not being able to help you.ue004我很抱歉不能帮助你。ue0041.作主语ue004动名词作主语时,句子有两种形式:ue004(1)动名词直接置于句首主语的位置上。ue004Playing tricks on others is something we should never do.ue004捉弄别人是我们万万不能干的。ue004Learning new words is very important for me.ue004学习新单词对我来说非常重要。ue004Talking is easier than doing。说比做容易。ue004(2)用形式主语it,把真正的主语——动名词结构移置句尾。但这种句子形式有一定的限制,作表语的只能是某些形容词或少数名词,如useful,useless,good,fun,no use,worth等。例如:ue004It is useless trying to argue with Shylock.ue004和夏洛克争辩是没有什么用的。ue004It"s worth making the effort.ue004这事值得去做。ue004Is it any good trying to explain?ue004想再解释一次有好处吗?ue004It is pleasant working with

again.ue004我又开始长胖了。ue004C.在动词forget,remember,regret之后,用动名词与不定式意义不同。动名词表示动作先于谓语发生,不定式表示后于谓语动作,例如:ue004I remember posting the letter.ue004我记得我已把信寄了。ue004I"ll remember to post the

(意思是,意味着)。例如:ue004We must try to get everything done in time.ue004我们必须设法及时把一切搞好。ue004Let"s try doing the working in some other way.ue004我们用别的方法做这工作试试。ue004I didn"t mean to make you angry.ue004我并不想叫你生气。ue004Yo ur plan would mean spending hours.ue004你的计划意味着要花费几个小时。ue004E.go on doing 和go on to doue004go on doing继续做一直在做的事;go on to do接着做另一件事。例如:ue004Please go on doing the same

Why can water be used to put out fire

Often the main way to extinguish a fire is to spray with water. The water has o roles: 1. In contact with the fire it vaporizes and this vapour displaces the oxygen (the volume of water vapour is 1 700 times greater than liquid water); leaving the fire with not enough bustive agent to continue and it dies out. 2. The vaporization of water absorbs the heat; it cools the *** oke air walls objects in the room e that could act as further fuel and thus prevents one of the me that fires grow which is by "jumping" to nearby heat/fuel sources to start new fires which then bine. The extinction is thus a bination of hyxia and cooling. The flame itself is suppressed by hyxia but the cooling is the most important element to master a fire in a closed area. hyxia - condition of severely deficient supply of oxygen I hope this can help your understanding. =) Because water seems to cost nothing and very abundent on earth. 参考: me ^^
