给英语降温议论文
俗话说“学好数理化,走遍天下都不怕”,而现在,英语已是当代人不可或缺的技能,我们重视英语当然毋庸置疑,但似乎这份热情过于高涨。水能载舟,亦能覆舟。对于这过分的热情,不禁问到:难道不该给英语降降温吗?
对于个人,英语作为高考的重要科目,所占的分值不容小觑,在高考这道坎前,英语的重要性不言而喻。如此一来,便有了千军万马过独木桥之势,不为其他,为了高考,为了分数。当然,也许还为以后的工作。如今的我们,便如那乌鸦一般,明知道自己不是雄鹰,却硬要像雄鹰般俯冲取食,最终只会得不偿失。我们今日一味地追求分数,一味地想要提高成绩,一味地做着今日播种、明日收割的美梦,但到头来,却因为自己急于求成、急功近利而收效甚微。对于这种情况,我们要大喊“停下!”我们花费了时间,却未取得预期的效果,着实让人感到失落。而上海外国语大学有研究表明,在所有学英语或其他外语的人中,真正能学会一门外语并能用外语流利表达、无障碍“跨文化交流”的,最多不超过5%。倘若我们坦然地看待分数,从容地对待考试,把用在英语的大量时间抽出一小部分用在自己感兴趣的学科上,反能有更大的收获,还能取得事半功倍的效果,何乐而不为呢?而最近北京市的高考体制改革实施的20xx年给英语降分,这一举动不也正表明了我们开始给英语降温了吗?
对于国家,早在鸦片战争时,中国在坚船利炮面前,发现西方先进的科学技术,提出要“师夷长技以制夷“,英语是必需的”敲门砖”。而在如今的一股股英语热浪下,许多国人热火朝天学英语而冷落了母语,开始趋之若鹜地报考托福雅思,报名的队伍蜿蜒数十米,而母语的等级考试却鲜有出现,许多的学生这不正是“邯郸学步”真实写照吗?尼采曾经指出:“母语是真正的教育由之开始的最重要、最直接的`对象。”正如其所说,我们万万不要捡了芝麻而丢了西瓜。英语兴,多少出于现实需要,弱者向强者学习,必然要屈尊纡贵,而当风水轮流转,失去的自信加来了,重新审视英语,是必然的事,当然也是一件好事。中国要走向世界,融入国际大家庭,而英语作为最重要的世界性语言,固然需要学习,要有专门人才做翻译、交流工作,但是未必需要全民学习,花大量的时间学习。耕别人的“田”不仅浪费时间,也荒废了自己的“自留地”,让汉语立于“危机”境地。我们应该在融入到全球化的同时,不是盲目地学习英语,而是取精去劣地学习,这样才会真正吸收这种文化。
给英语降温,我们应积极地参与,冷静地面对这种形势;给英语降温,我们更要取精去劣地学,跨过英语这座大山;给英语降温,我们定会成为雄鹰,收获更大的成功!
篇2:怎样给城市“降温”
怎样给城市“降温”
“城市热岛”效应给居民的正常生活造成很大影响,特别是夏季高温时节,“热岛效应”会加剧升温作用,导致人们烦躁、中暑、精神紊乱,甚至会诱发心血管病等一系列疾病,严重影响人们的身心健康。
有没有办法来治理“城市热岛”现象,让城市“降温”呢?
首先应该从城市建筑的规划、结构、材料等方面着手,努力消除产生“城市热岛”现象的人为因素。在城市总体规划时,要科学合理地做好布局,给城市留出足够的“通风道”,以便于建筑群的热量快速传递和散发。要打造具有隔热和遮光结构功能的建筑物,可以给建筑物的外表面涂上一层吸热率低的浅色涂料,用来反射和遮蔽太阳光的辐射;也可以在房顶、外墙、道路上种植各种绿化植物,用来遮挡太阳光的辐射。城市道路、立交桥的路面可以使用具有反射阳光特性的.新型材料,来代替传统的沥青和水泥。据测试,有一种新型材料可让路面温度降低15℃;而另一种道路铺设材料既能“吃”水又能“留”水,由它铺成的“透水性道路”在盛夏季节能够把雨水存储在道路下面,使路面温度降低10℃左右。
有人还另辟蹊径地提出了一个城市“降温”方案,即在市中心或大型建筑群区域内构建地下专用管道冷却系统,把该区域内的热量全部带走。具体做法是,先将周边地区建筑物内的热量全部排到这个管道系统中,再利用已引入管道的河水或海水,通过其不断循环将热量带走。据称采用这种做法可使地面温度比其他地区低5~10℃。
此外,大力推进城市绿化工程,消除扬尘的裸地,营造一系列由公园、水景、湿地、公共绿地和林荫隔离带等组成的绿色生态环境,再辅以喷泉、喷雾、细水雾浇灌等人工水蒸发补给系统,就可以进一步提高城市地表的比热容(即每升温1℃所需要的热量);有计划地控制空调等高热量排放设备的使用,加快“燃煤改燃气”、“燃油改电力”等提升耗能效率和减少污染排放措施的步伐。这些都是给城市“降温”行之有效的对策。
篇3:怎么给头部降温方法
保护大脑是现场心肺复苏最重要的环节之一。过去不少患者经过复苏抢救,心脏已经复跳,但是由于大脑缺氧而发生了严重损害,结果不是与世长辞就是处于植物人状态,令人扼腕叹息。因此,现代医学对在复苏中保护大脑越来越重视,传统的心肺复苏已经变成了心肺脑复苏。
大脑是人最重要的脏器之一,它是指挥人类一切活动的总司令。同时,大脑也是最脆弱的器官和最需要氧气的器官。人的脑组织的重量虽然只占身体总重量的2%,但它的耗氧量要占到人体全部耗氧量的20%。婴幼儿和儿童的脑耗氧量更要高达50%!
由于大脑是高度需氧器官,因此对缺氧的耐受性最差。常温情况下,脑细胞在没有氧气供应时超过4分钟就会发生不可逆转的坏死。还有一点必须指出:在患者心脏骤停后,其脑损害的程度与本人体温和环境温度成正比,温度越高,脑细胞代谢越快,坏死越快。反之,温度越低,脑细胞坏死越慢。所以在寒冷发病现场抢救患者,复苏成功率较高。
怎样在复苏时保护患者的大脑呢?要点就是尽快创造一个救命的“严冬”――采用各种措施降低患者头部和全身的温度。冷敷是现场抢救时最常采用的手段。把碎冰块儿装在塑料袋中,扎紧后敷于患者颈部、枕部、头顶及前额,(塑料袋与患者皮肤之间要有薄布相隔,以免长时间冷敷造成冻伤),冰块儿融化后要及时更新。现场无冰块儿时可就地取材,如冰箱中的冷冻食品以及冰棍、雪糕等都可加以利用。
篇4:怎样给DVD光驱降温
一般来说,光驱的速度越高,发热量就越大,特别是在使用DVD观看电影时,长时间使用后其表面会有烫手的感觉,如果光驱的温度过高,会影响光驱的寿命,所以使用过程中应尽量为光驱降温。可以采取下面的几种方法:
(1)打开机箱外盖。打开机箱盖以后,机箱内部空气流动加快,光驱就能够充分和外界接触,不仅可给光驱降温,其他硬件的温度情况也会得到改善,这也是众多DIYer常用的一种降温方法,
(2)使用光驱风扇。如同硬盘风扇一样,目前市面上也有为光驱定制的散热风扇,将风扇安装在光驱上面,接上电源就可以使用,并且会起到很好的降温效果。
(3)长时间读盘以后,可打开光驱,使光驱托盘一直开着,这样光驱内部的机械部件就可以和外界空气接触,使温度平衡。但要注意安全,不要碰到弹出的光驱托盘。
篇5:如何给地球降温阅读答案
(1)气候学家已发出警告:未来1,全球气温将升高1.5℃~6℃,海平面将升高154.5厘米,沙漠将更干燥,气候将更加恶劣,厄尔尼诺现象更为严重,全球变暖将直接或间接影响人们的生活。如何给地球降温?科学家提出了许多奇思妙想。
(2)美国氢弹之父、物理学家爱德华.特勒去死以前曹有过设想:向空中抛洒铝和硫的粉末,给地球降温。按照他的计算,向空中抛洒100万吨铝硫粉末,可以使日照减少1 %,从而起到降温作用。特勒提出的办法是要模仿大规模的火山爆。1991年,波及范围达数百万千米的皮纳图博火山灰使地球气温下降了0.4lC,而且持续时间达好几个星期。特勒设想:可以用飞行于13千米高空的飞机和部署于赤道上的美国海军大炮,向空中抛火山灰。但生物化学家们却给这种主张泼冷水,他们认为,散布于空中的这些硫和铝的微粒,很可能会严重干扰同温层。特勒还与人合作研究过其他使地球降温的方法:在轨道上放置5万面反射镜;发射一颗巨大的卫星,悬于地球与太阳之间,以挡住部分太阳辐射。
(3)除了特勒以外,还有许多科学家也在苦苦思索,希望能找到奇妙的办法给地球降温。美国物理学家洛厄尔.伍德有一个同特勒的设想一样离奇的计划:在地球和太阳之间万有引力互相抵消处(即拉格朗日点),安装一面直径为20xx公里的半透明镜子。他认为,这面巨大的滤光镜不但能减少温室效应,而且能充当地球的空调器:改变滤光镜的倾斜度,以增加或减少透过它的太阳辐射量。但谁来支付超过1000亿美元的巨额费用呢?此外,这面滤光镜不但会破坏同温层,而且还有可能妨碍紫外线的通过(紫外线具有清理太空的功效)。
(4)有科学家从加强地球对太阳辐射的反射率的角度,探索给地球降温:将数以十亿计的白色聚苯乙烯高尔夫球投向海洋;将地球上的所有房屋的房顶都涂成白色。美国的一位科学家提出了一项更具有诗意的方案:将数千平方公里的阴云染白。通过向阴云喷一些微粒,使微小的雨滴数至少增加10%。这样,由于光学作用,层积云就会被照亮变白,就会反射更多的太阳光。
(5)还有人提出用深埋二氧化碳的办法给地球降温。美国和欧盟已拨巨款来研究在海洋和地层中埋藏二氧化碳的办法。从理论上讲,海洋和地层可以贮藏人类在几千年间生产的二氧化碳。研究人员要验证的是,二氧化碳溶解在海水中,是否会干扰海底生物的生存,因为二氧化碳溶解于海水后,会使海水酸化。

篇6:英语议论文
How to deal with the setbacks
We’ve all hit that bump in the road, the setback, the problem. What sets people apart is how they react to that bump. Are you one to spin out of control, in despair? Or do you grab a hold of that wheel and steer yourself straight? Whether it’s a school assignment, a work project, or a volunteer mission, we all encounter things that slow us down. You just have to keep in mind that a setback is only temporary and greater things lay ahead.
It is easy just to quit, give up and ignore the hard work you have put into something. But at SparkPeople, we believe in the “two steps forward, one step back” philosophy. So what if something bad happens? Keep moving forward, developing what you have. You’ve already built a solid foundation on which you can rely. Hard work can’t be overlooked.
So how can you react when something doesn’t turn out as you’ve expected? First, be objective. Step back and look at the situation. Take responsibility where it is due, but don’t place blame on others. Is your setback really that significant, or will it just require a little extra exertion on your part? Come to terms with it and then start planning your next move. Ask for help. Don’t be afraid or ashamed to do this. Oftentimes, people are more than willing to give you support and advice, maybe even after being in a similar situation. You don’t have to be perfect; after all, nobody else is.
Bounce back. Reevaluate the goals you should have set for yourself at the beginning and retool them as necessary. Goals should be realistic and specific, but that doesn’t mean they can’t be flexible and are allowed for minor impediments. Instead of looking at your project as a disaster or failure, view it with success. Concentrate on how great it will feel after it is finally done, after you have put your all into it. Instead of focusing on a possible unsatisfactory performance one single time, take a moment to sit back and reward yourself for all that you have accomplished.
Above all, don’t live with regrets. Approach life with perseverance and dedication to the things that matter most to you. Success is never easy. It remains up to you whether you will give up, or fight through the tough battles to earn whatever it is you want.
A fragment of a poem by Ralph Waldo Emerson is telling:
“Finish each day And be done with it.
You have done what you could. Some blunders and absurdities have crept in. Forget them as soon as you can.”
Move on with your life. Keep reaching for your goals and you will achieve them. One minor setback is nothing if you really want something and are willing to work for it.
篇7:英语议论文
关于个人责任
We Chinese place a high value on responsibility. It is traditional deal for us Chinese to take care of our parents. We owe them a great deal for the love they give us while we are growing up. It is right, then, when they are getting older with each passing day, we help them and see that they are well cared for. In this way, we give back some of the love and care they have given to us.
As loyal Chinese citizens, we must have a strong sense of responsibility to our country. I t is our duty to keep China strong in the eyes of the world. Therefore, we should study and work hard for China’s strongness which also depends on the advanced science and technology. We must be willing to join the Army and defend our country, would we be threatened by an invader(侵入者). In short, to be a responsible citizen ,we must put our country’s welfare above our own needs. Finally, we must remember that we have a responsibility to the world we live in. It is important that we learn to live in peace with the other nations of the world and to protect our environment.If we carry out these responsibilities, we will be respected (受尊敬的)citizens of our country.
篇8:英语议论文
Many people are inclined to do one job in their lives. In their opinions, people who change their jobs frequently are superficial and tactless. They believe that the only way to success is to stick to one job, for constant practice in a professional field helps make an txpert.
But there are still many people who don’t agree. They argue that change means progress. If you are not satisfied with your present job, of course you have the right to replace it with a more challenging and better paid one. Every change is a step to further success. This idea may be. the reason why they change their jobs so often.
For my part, I think it reasonable to change your job if you have a better opportuniry. But once you have found a position where you can fully display your ability, it is advisable to settle down to it and put all your efforts into it. Only in this way, can you get the true joy of achieving your goal.
我对更换职业的看法
许多人喜好终身从事一种工作。他们看来,经常更换职业的人浅薄,不老练。他们认为成功之道是终守一职,因为在自己的业务领域中反复实践有助于成才。
但是,也有许多人不同意以上观点,他们认为变更就是进步。如果你不满意目前的工作,当然你有权力换一个更具挑战性的,待遇更好的工作。每一次更换就会向着更加成功迈进一步。这种观点也许是他们不断更换职业的原因。
就我而言,我认为若有更好的机会,更换一下职业是合情合理的。但是,一日找到一份你能展示你的才干的职业,就该专心致志把它做好。只有如此,你才能真正享受到取得成就的欢乐。

My opinion on copying others' homework
It is konwn to us all that some students copy others' homework,their reasons are as below:first of all,the homework is too much and always difficult;the second,they are not intrested in the lessons;and the third,the aim of finishing their homework is to please the teacher.
In my opinion,copying others' homework is not good,because it's against the rules of the school.We should be honest and work hard to get high scores.If we have difficulties,we can even ask the teacher or our classmates for their help.
篇10:英语议论文
In the picture we can see that a man is fishing attentively by the lake.Behind him there is a scholar who is stealing the fish in the man’s bucket.It is obvious that the drawer of the picture tries to reveal a serious problemin the academic circle of our country — plagiarism. In recent years academiccheats have become rampant. Quite a lot of graduate students and scholars“use” others’ ideas, articles and papers without acknowledging the sourceof information.
They copy them without the fear that they might be caught.For a long time we paid less attention to the problem of plagiarism, butnow we are increasingly aware of its negative effects. Plagiarists’misconduct simply mean “stealing” others’ intellectual and academicaccomplishments, which not only depreciates their own humanity but contaminatesthe climate of the academic circle. Academic falsification is like an epidemicdisease that spreads fast and will destroy the healthy development of academicstudies. What’s worse, these plagiarists have set a very disreputable exampleto the younger generation.
So what attitude should we hold towards it? From my point of view, weshould resolutely battle against this ill phenomenon. Education of moralityshould be strengthened among the scholars and students. Those who steal others’academic achievements should be given severe punishment whenever they arespotted. If necessary, we can resort to the law to protect the interest of theoriginal writer and inventor. We must recognize that fighting againstplagiarism requires our persistent efforts.
翻译
在画中我们可以看到一位男子正在专心地在湖边钓鱼,在他身后有一位学者模样的人正从钓鱼人的鱼桶中偷鱼。显然,作这幅画的人是想揭示我国学术界的一个严重的问题—— 剽窃。近年来学术欺诈盛行,有不少研究生、学者“利用”别人的想法、文章和论文而不注明信息来源。
他们抄袭他人作品,不怕被抓。对剽窃问题很长时间以来我们关注甚少,现在我们越来越多地意识到它的负面影响。剽窃行为其实就是“偷”他人的知识和学术成就。剽窃不仅贬低人格,而且污染学术风气,它会像传染病那样迅速蔓延,破坏学术研究的健康发展。更糟的是,这些剽窃者给年轻的一代树立了坏榜样。
对剽窃我们应该持什么态度呢?我的观点是,我们应该与剽窃现象作坚决的斗争,对学者和学生加强道德教育。对那些对剽他人学术成果的人,一经发现严厉惩罚严惩不贷。如有必要,我们应该采用法律手段,保护作者和发明人的利益。我们必须认识到与剽窃斗争需要作出抗不懈努力。
