雅思作文范文 (政府应该怎样促进代替新能源
雅思写作大作文考官范文:政府推动新能源发展
Write about the following topic:
Governments should make more effort to promote alternative sources of energy.
To what extent do you agree or disagree with this opinion?
Model Answer:
It has been known for some time now that a move towards sources of energy which are not carbon-based is urgently required to stop the effects of global warming. In my view, there are too few governments who seem to be promoting the use of other types of energy such as wind, wave, solar and nuclear sources of energy.
Governments at present are too reliant on coil, oil and gas. Although some governments are doing research into the use of alternative energy sources, many are not. Energy from the wind, the sea and the sun does not pollute the environment and is an everlasting source of power. Nuclear power is clean, and although it is not totally unproblematic, it would provide a large amount of energy and dramatically improve the environment. Countries such as France have made good use of nuclear power.
My feeling is that more use could be made of wind power. In some countries,there has been a reluctance to use wind turbines, even in areas which are not densely populated, as some people believe they are eyesores. Personally, I believe they are not only useful, but beautiful as well. Governments should spend more time and effort promoting the benefits of this source of energy and trying to make the public understand the reason for change.
In conclusion, I believe that, if governments forced everyone to have a wind turbine and solar panels on the building they live in, made more use of wave power and built more nuclear power stations, then they would manage to avert the dangers that are seriously threatening the Earth.
思路:1. 核能源的好处多多。第一,它的发电效率更高。举例,一座核电站就可以代替数座普通电站来为整座城市发电,这意味着我们对于煤矿和天然气的开采能够被抑制,很好地避免了资源枯竭。第二,核电站的发电过程是完全无排放,无污染的,这意味着那些烟尘和废气能被避免,也很好地缓解了全球气候变暖。
2. 然而,核能的危险不可忽视。核电站的泄露和爆炸会产生严重的辐射,这会导致疾病和死亡。最典型的的例子就是乌克兰的切尓诺贝利核事故,它导致了上万人的死亡,以及整座城市的废弃。
范文:
Nowadays, there is a popular argument that we should massively use nuclear energy to meet the expanding requirement of power in an age of overpopulation. Personally, I believe this assertion is problematic because it underestimates the uncertain risks resulting from this energy.
Admittedly, one main reason of supporting this new energy is about its high efficiency in making power. According to scientific statistics, a single nuclear plant can generate several times as much power as a thermal power station based on coal or natural gas, which means environmental-destruction activities like mineral digging and fossil fuels exploiting will be prevented. What is more, the level emission of carbon dioxide is much lower than traditional energies during the production. That is to say, by using nuclear technology for power generation, the number of smog and industrial wastes discharged in air and water would be minimized, thus substantially relieving the stress of pollution and global warming.
However, the most worrying aspect of nuclear power is its unsafety. The leaking and explosi
这是雅思的作文“气候变化对事业的影响”,这里给出几篇范文

To begin with, climate change is bad for many businesses. Although it is hard to estimate in exact terms the extent to which various businesses may be influenced, it has been evident that climate-related disasters like droughts and floods and hurricanes, are starting to have an impact on businesses of many kinds. Globally, climate change presents afundamental threat to business prosperity, and it is increasingly recognized as a risk for business owners. For example, they will face rising insurance costs, or the insufficient supply of power and water. So, if they fail toinnovate so as to adapt to the worsening climate change, bad effects would fall on them and leave them out of business.
首先,气候变化对许多企业是件坏事。虽然很难准确估计各种企业可能受到的影响程度,但很明显,干旱、洪水和飓风等与气候有关的灾害开始对各类企业产生影响。在全球范围内,气候变化对企业的繁荣构成了根本性威胁,人们越来越认识到气候变化对企业主来说是一种风险。例如,他们将面临保险成本上升,或电力和水供应不足的问题。因此,如果他们不能创新,以适应日益恶化的气候变化,不良影响将落在他们身上,使他们失去业务。

Although it is not great to acknowledge that bad things can create opportunities, climate change does open up new possibilities for at least two business sectors. One area ripe for growth is renewable energy. In this area, businesses have set ambitious targets for wind, solar and hydro-power, and they may attract huge amount of investment. Meanwhile, eco-friendlyconstruction companies can find new opportunities who help cities prepare for changes in climate as more and more people will live in urban areas and create a pressing demand for a host of infrastructure services, like water and electricity.
尽管承认不好的事情可以创造机会并不好,但气候变化确实为至少两个商业领域开辟了新的可能性。可再生能源是一个适宜增长的领域。在这一领域,企业为风能、太阳能和水力发电设定了雄心勃勃的目标,可能会吸引大量投资。与此同时,随着越来越多的人生活在城市地区,对水电等一系列基础设施服务的需求日益迫切,环保建筑公司可以找到新的机会,帮助城市做好应对气候变化的准备。
解析
(1) 本段讨论气候变化可能给企业创造的新机会,本段用列举法。
(2) Acknowledge 承认
(3) Open up 催生;开放
(4) Be ripe for... 适宜做......
(5) Eco-friendly 环保的
(6) A pressing demand for... 对......的迫切需求

04
In conclusion, climate change will continue to be a long-term risk to many businesses. However, those forward-thinking few can take immediate action and turn this vicious trend into new opportunities.
总之,气候变化仍将是许多企业的长期风险。然而,那些具有前瞻性思维的少数企业能够立即采取行动,将这种恶性趋势转化为新的机遇。

跪求0708四川 What can I do for our environment? Everyone can do something for our environment. For me, I should try to save electricity in my daily life. For example, if I am the last person leave the classroom in the evening, I will always remember to turn off the lights. In order to protect our forests, I will use paper wisely. I should try to use both sides of paper whenever it is possible. I will not use things like paper cups and disposable chopsticks because they are made of wood. I believe that doing all these *** all things will improve our environment and help make our world a better place to live in. 08陕西Notice Our monitor suggests that we have “Friday News Hour”. But some clas *** ates do not agree. We will have a class meeting in English tomorrow afternoon to discuss this suggestion. Please prepare your talk and take an active part. May 6th, 2008 Dear fellow students, Our monitor suggests that we have “Friday New Hour”. I think that it is a good idea. Everyone knows that we are busy all day. Seldom do we know what is happening both at home and abroad, let alone what we can do for our country. By reading newspapers we can get more information about the world outside. So I think “Friday New Hour” can broaden our mind and enrich our school life. What's more, it will help us improve our reading skills. As for my suggestion, I think it's better to have it ice a week. And we should make a choice about what we'll read. I am sure everyone will benefit a lot from this activity. 08福建Dear sir, I'm Li Hua from Fujian. When I was reading the advertisement , the aim of this activity impressed me greatly, I think it instructive to learn to live together by living together. It is a good opportunity for the only child like me to learn to share and work together. Therefore I remend myself to you without hesitation. As a boy of 17, I am outgoing, good at English and have experience of working well with children aged from 7 to 12, I think it is a kind or win-win activity. For one thing, I can help take care the children. For another thing, I can improve my English, make more friends, and enrich my life during the summer vacation. I am looking forward to your early reply. Sincerely yours, Li Hua 08安徽Dear David, I'm glad that you've noticed our efforts directed towards environmental protection. Thank you for your concern. As too much use of plastic bags has caused serious white pollution, our govenment encourages us to use environment-friendly shopping bags. These bags are made of a variety of material that can be easily treated when they bee rubbish. Besides, they can be reused. More and more people in China have realized the advantages of such bags and started using them. I believe that the wide use of these shopping bags can greatly improve our environment. This is one of the many steps we are to make our country an even cleaner place. Yours, Li Hua 08湖南Sample 1: Thomas Edison Born in American, Thomas Edison was a great scientist and inventor. He once thought to be a boy who was not worth educating. In fact, he was a man full of imagination. I admire Edison a lot because of his great contribution to the world. He had more than 1000 inventions. In his little time, he was always eager to know how things worked, which helped him to earn the nickname “the Wizard of Meio Park”. He was also so diligent that he worked day and night. And this explained why he had so many inventions. What impresses me most is his famous saying, “genius is one percent inspiration and niy-nine percent perspiration”. Probably I cannot be an Edison myself, but I can be a hardworking learner. From him, I realize the secret to success is not when and where you were born, but what you are doing and how you do it in your life. Sample 2: Helen Keller Every time I read “…if I had the power of sight for three days, I cannot help being moved by its author Helen Keller, an ordinary but great American woman. I admire Helen because she is optimistic about life. She became deaf and blind when she was 19 months old. Since then she lived in a world of darkness and silence, and munication seemed only a dream for her. But she never gave up and struggled to lead an active life. Under the guidance of her teacher, Ms. Sulliven, Helen learned to read and write, and became a famous writer. For a disabled person like her, this was really a wonder. Helen has set an excellent example to all of us. Her story tells us that we should value what we have and try our best to overe any difficulty in life.

在生境不变,成种率极低的情况下,这些生物在几百万年时间内没有发生什么变化。于是相应的就形成了一些延续了上千万年的古老的生物,同时代的其他生物早已绝灭,只有它们独自保留下来,生活在一个极狭小的区域,被称为“活化石”。
1938年在非洲东南部海中,首次发现残存的总鳍鱼类矛尾鱼,是世界闻名的1种活化石。我国现在的裸子植物银杏、水松和哺乳动物大熊猫等,均被世界公认为珍贵的活化石。
另一些在地史时期,曾广泛分布而长期生存至今的动物,如腕足类的海豆牙等,也是“活化石”,但它们不是孑遗生物。
总之,孑遗生物一定是“活化石”,但“活化石”不一定都是孑遗生物。
化石是埋藏在地层里的古代生物的遗物。最常见的化石是由牙齿和骨骼形成的。古代动物死后,尸体的内脏、肌肉等柔软的组织很快便会腐烂,牙齿和骨骼因为有机质较少,无机质较多,却能保存较长的时间。如果尸体恰好被泥沙掩埋,与空气隔绝,腐烂的过程便会放慢。泥沙空隙中有缓慢流动的地下水。水流一方面溶解岩石和泥沙内的矿物质,另一方面将水中过剩的矿物质沉淀下来或成为晶体,随着水流会逐渐渗进埋在泥沙中的骨内,填补牙齿和骨骼有机质腐烂后留下的空间。如果条件合适,由外界渗进骨内的矿物质在牙齿和骨骼腐烂解体之前能有效地替代骨骼原有的有机质,牙齿和骨骼便完好地保存成为化石。由于化石中的大量矿物质是极为细致地慢慢替代其中的有机质,所以能完整地保存牙齿和骨骼原来的形态,连电子显微镜才能看清的组织形态都能原样保存。天长日久,骨骼的重量不断增加,由原来的牙齿和骨头变成了还保存牙齿和骨头原有的外形和内部结构的石头,这个过程被称作“石化过程”。
除了牙齿和骨骼外,有的动物的粪便也能成化石。例如,有的肉食动物吃肉时是连着碎骨一起吞下的,粪便里有许多没有被消化掉的碎骨,碎骨不容易腐烂,所以也能成为化石。脚印也能成为化石。人或动物踩在泥沙上,造成脚印。泥沙干后,脚印又被另外的物质填满。两种物质都被后来渗进去的矿物质石化后保存下来,但是两种物质的性质不同,软硬不同,容易风化或破坏的程度也不同。一种物质被风化或破坏后,另一种物质便表现为脚印化石。
化石形成的条件
形成条件:
虽然一个生物是否能形成化石取决于许多因素,但是有三个因素是基本的:
(1)有机物必须拥有坚硬部分,如壳、骨、牙或木质组织。然而,在非常有利的条件下,即使是非常脆弱的生物,如昆虫或水母也能够变成化石。
(2)生物在死后必须立即避免被毁灭。如果一个生物的身体部分地被压碎、腐烂或严重风化,这就可能改变或取消该种生物变成化石的可能性。
(3)生物必须被某种能阻碍分解的物质迅速地埋藏起来。而这种掩埋物质的类型通常取决于生物生存的环境。海生动物的遗体通常都能变成化石,这是因为海生动物死亡后沉在海底,被软泥覆盖。软泥在后来的地质时代中则变成页岩或石灰岩。较细粒的沉积物不易损坏生物的遗体。在德国的侏罗纪的某些细粒沉积岩中,很好地保存了诸如鸟、昆虫、水母这样一些脆弱的生物的化石。
初三那一年
还是走吧,甩一甩头,在那夜凉如水的路口。那唱歌的少年已不在风中,
你还在怀念,那一片白衣飘飘的年代。
校园里的木棉花开了,带着新生的喜悦和耀眼的春的气息。让冬天掩埋得
太久,该是花开的时节了。辉在我身边若有所失地说。我莫名地对春天产生了
一种敬畏之情,四季中总有如此明媚的季节,可是我们的生命呢?能有几个这
样的春天?春天过后,我们将面临一次艰难的选择。黑色七月,我们的未来,
你究竟是怎样的呢?明年的今天,我们又将在哪里?木棉花在微风中轻轻的叹
息着
我们冲进教室的时候,上课铃刚响完。数学老师站在讲台前:快点,都什
么时候了,还有心情玩?我和辉尴尬的摸摸后脑勺,老师望着我们,无可奈何
的笑了。我坐在座位上望着黑板,却发现老师的嘴边都干的起了泡,可她还在
不停地说着定律、定理。恨不得把她知道的东西都喂进我们的嘴里,脸上是一
种和谁抢时间似的焦灼,老师也是用心良苦啊!我心里酸酸的。
初夏的清晨,走在那每天必经的路上,感觉有一种想飞的冲动和想笑的欲

写一篇雅思作文,有关科技与环保的250字,今晚就要,坐等发展与环保
世界各国中,要想在国际中树立威望,就必须加大力度发展本国的经济。在工业的生产中,人们似乎忽略了环保这个事情,一心只想在经济利益中受益。你别以为你没有吃亏,你在经济中受到一份利益,就会在环保上吃一份亏。日积月累,吃亏的最后还是自己。
新中国成立后,中国工业突飞猛进,经济值年年提高很多,在国际中的地位也慢慢上升,可是环境的破坏程度也越来越大。所以说既要发展迅速,又要环保,就不得不走可持续发展道路。
既然是要走可持续发展道路,就必须按条理进行。不能先开发、后治理,必须以“防”为主,防治结合,综合治理;谁开发、谁保护,谁污染、谁治理。单单靠个人是无法达到预计目的的,也必须依靠群众的力量来保护环境。
让我们共同努力创造我们美好的生活吧!
不知道能否帮助你解决问题
环境类雅思作文有哪些素材我曾经以为“漠然”是由心底迸发的毫不在乎、冰冷无情,我也固执地把它与冷漠画上等号,并且自私地从其中列数出他的种种冷酷与无情,殊知这样看似无情的外表下,竟贮存这那样一棵温暖的心。
诚然,父爱看似漠然却毫不冷漠。
我也确实有个与一般孩子不一般的童年,没有可以骑在父亲脖子上采桑葚的欢笑;也没有与父亲一起河畔垂钓的怡然,在我的的印象中,他留给我的始终是个后背,都说催弦先生的《背影》写得极好,我却从不曾在我父亲的背影中读出些许柔情;也听崔京浩的父亲:“父亲是儿登天梯”,可始终不曾从他那儿寻到过一毕安慰。
随着年龄的增长,父爱的“匮乏”赵来赵令我不满,我努力做好功课,每次考试都考九十多分、一百分,只换他一句:“下次考好才是本事,”,我也曾故意调皮捣蛋,弄得老师带家长,希望引起他的注意,让他多关爱我,怎奈他什么话也不说,是一个劲冲老师点头,我逐渐从自以为以的“大爱无言”的走出来,再被父亲的那近乎“冷漠”的情感冰冻。
那日因为我找学习资料进了父亲的书房,从层层叠叠的书籍下拖出了一个似使用了多年的小木箱,虽显得破旧却纤尘不染,似乎父亲经常擦洗,好奇心作逐的我打开了木箱,那是一逢的奖状、照片、报纸……各类纸张上的主人公只有一个,那便是我,有六岁时他叠的小青蛙,有三年级时得的书法奖状,有十二岁那年儿童节作主持时用过的小领结……有最近“不翼而飞”的床头那张有我发表文章的报纸,有上次其中考试的成绩单,十九年的点点滴滴噢,在小小的木箱中展露无遗,我可以想像出父亲一人在灯下翻看这些奖着时嘴角露出的微笑,想像他是怎样一边满足的哼着小调,一边整理小木箱中东西的模样,我突然理解了父爱的含义。
也许全天下的父亲都是相似的,有着山一般巨大而深沉的爱,而这些爱,往往是隐藏在那些表面的无所事事,漠不关心的假象之下。
父亲的爱,从不挂在嘴上,“至爱无声”,几近漠然却如清清细流滋润我的胸怀;父爱无言,大善无声,虽看似平凡的冷漠更深处却 *** 如火,终生不渝。
我想唤您一声“爸”,不管是否依旧如以前那么淡然、无所谓的表情;我想努力学习,为你争脸,不管你是不是还是那么严厉地指责我的不尽之处,十多年的时间还算太长,我也终于明白,漠然不是冷漠,您的爱是我永久的太阳。
漠然相爱,寂静喜欢。
深度解析:雅思大作文之环境类话题怎么破雅思写作话题十大分类之环境类
摘要: 马上就要过年了,为了让大家在新的一年能学习进步,我为大家带来的雅思写作话题十大分类之环境类以下内容,希望大家在过年休息的时候,能适当的调整学习时间,不但能好好的休息,也不要忘了好好学习,争取在年后能有一个全新的自己。
雅思 考生在备考 雅思写作 的过程中,需要对雅思写作的考题进行话题分类,并针对每类题目准备相应的解题方法和写作思路,积累不同话题的素材和词汇表达,进行限时训练,提高写作速度。
环境类
1. 环境和自然资源的保护
母题:Environmental problems are too big for individual countries and individual people to address. We have reached the stage where the only way to protect the environment is at an international level. To what extent do you agree or disagree with this statement? (040228, 040515, 110507)
解题:采用让步的结构,承认题目观点及其合理性,不可否认,保护环境的确需要国际合作,第一,一些全球性和世界性的环境问题,如全球变暖,臭氧层空洞,石油泄漏和海洋污染等,不仅影响了单个国家,而且对整个地球的环境都造成了影响,因此需要多个国家共同努力来解决第二,在保护环境的过程中,通过联合多个国家来采取行动,我们可以引进其他国家先进的技术和设备,更好的解决一些区域性的环境问题。但是,这并不就是说咱们可以忽略个人和单个国家的作用。国际合作、企业、 *** 、个人,都可以为环境保护做出自己的努力。进一步论证个人观点,拓展段落。
子题:个人不能保护环境,只有 *** 和大公司才能,同意吗?个人能不能保护环境?很多人知道环境保护很重要,但是自己却不采取任何行动,这是为什么?
母题:Fossil fuels, such as coal, oil, natural gas, are used in many countries. But in some countries, the use of alternative sources of energy, including wind and solar power, are encouraged. Is this trend a positive or a negative development? (090530)、
解题:这道题目问的是新型能源或可替代能源alternative energy的优缺点。优点:取之不尽用之不竭inexhaustible,可再生 renewable,更环保environmentally friendly,比较清洁干净clean缺点:核能nuclear power可能会引发安全事故,核废料处理不易,水能hydropower会破坏生态环境upset the ecological balance, 太阳能solar power 蓄能困难,效率低,成本高,风能wind power不稳定,会产生次声波污染infrasonic wave等.

求助!雅思作文批改首先你的词汇和语法都没什么问题
然后就是段落结构了
照你的意思就是totally disagree
我不知道如果以Disagree to a large extent为核心会不会比较好
因为完全否定Work of artist可能会有些吃亏
第二段你分析了艺术作品都是靠科技做出的器材或者材料
感觉上价值不大 因为不如去分析艺术作品的价值更好
第三段分析了马斯洛需求阶层
你的论点还是有些争议性的 比如精神需求为何就一定不如科技所带来的基础物质需求 也有不少人疏于物质而追求精神的 而科技的作用是可以贯穿所有阶层的
第四段讨论科技的作用
easing后需要个连词吧。。或者thanks改为due?
总的来说你的词汇语法都没什么问题 主要是注意逻辑上要严密些 选择更合理的论点
以上就是我的观点 要是觉得有用就采纳吧 呵呵
有几个连接词用得不对吧,拼写也有错误。
“individuals will surely not endeavor to harm the environment. By contrast, he will try every means to protect the environment.”
The behavior of individuals plays a significant role in environment protecting as well.
.......还有你的句子好碎,有的完全可以复合在一起的。
不过语言准确性还算不错,逻辑也算得上清晰。应该是7分左右的文章吧。

Test1给我们提供了一篇3.5分的小作文,为此特发此文,提供一篇质量高一些的文章,希望能给想要拿高分的鸭鸭一些有价值的参考。尤其是在语言多样性和信息连接性方面。
(p.s.为了阅读此文便利,特意将汉语版陈列如下,同时也让鸭鸭们感受汉语和英语之间的转化过程。)
这两个饼状图显示了能源在澳大利亚家用和温室气体排放的信息。
The
two
pie
charts
illustrate
statistical
information
respectively
regarding
how
energy
is
used
in
an
average
Australian
household
and
the
greenhouse
gas
emissions
that
result
from
these
energy
uses.
我们先来谈谈澳大利亚的能源使用情况。heating占据了整体的能源消耗的最大比例,42%。而the
figure
for
water
heating也占据了一个大的比例,仅比heating低那么一点,30%。相比之下,refrigeration,lighting,cooling只占了比较小的一部分比重,分别占据7%,
4%和只有2%。之后,剩下的15%的能源消耗是用在其他家电上的。
First
let
us
talk
about
the
energy
consumption
of
household
facilities
in
Australia.
Heating
possesses
the
largest
proportion
of
total
energy
usage
in
family
unit,
accounting
for
42%,
followed
by
the
figure
for
water
heating
which
also
occupies
a
large
percentage
with
30%.
In
contrast,
the
data
for
refrigeration,lighting,cooling
are
much
less
significant,
7%,
4%
and
only
2%
respectively.
Finally,
the
remaining
15%
of
the
consumption
is
used
on
other
appliances.
再看看以上提到的这些家电的温室气体排放情况,与上图存在很大不同。首先,能耗最大的heating在温室气体排放方面略有逊色,以15%的比重排在第三。而最多的温室气体排放来自于water
heating,32%。
相比之下,refrigeration,lighting,cooling的温室气体排放量几乎都是它们的能源使用量的两倍。其他家电所产生的CO2,占据了剩下的28%。
As
for
the
situation
of
greenhouse
gas
emissions
from
the
appliances
mentioned
above,
it
largely
differs
from
the
last
pie.
First,
heating,
which
consumes
the
greatest
amount
of
energy,
shows
a
smaller
share
in
greenhouse
gas
emission,
listed
in
the
third
place
with
a
proportion
of
15%,
while
the
biggest
share
of
emissions
is
from
water
heating
(32%).
By
comparison,
proportions
of
greenhouse
gas
emissions
in
refrigeration,
lighting
and
cooling
almost
double
their
figures
for
energy
use.
CO2
derived
from
other
appliances
consist
of
the
remaining
28%.
根据这两个饼状图,heating是最为环保的家电,而water
heating不仅能耗大,CO2的排放量也相当大。refrigeration和lighting虽然能耗比较小,但是温室气体的排放量也比较大。
Overall,
it
is
noticeable
that
heating
is
the
most
environmentally
friendly
appliance
while
water
hearing
not
only
consumes
more
energy
sources
but
also
give
out
the
most
carbon
dioxide.
Meanwhile,
although
refrigeration
and
lighting
consume
less,
they
emit
more
as
well.
TIPs:文章的语言的多样性取决于主语的多样性和灵活性,该篇所用主语的形式如下:
1.
Heating——题目中所给的名词
2.
the
data
for
refrigeration,lighting,cooling——“数据”作主语
3.
the
remaining
15%——数字作主语
4.
the
biggest
share/proportions
of
greenhouse
gas
emissions——比重词作主语
5.
CO2——题目中greenhouse
gas的同义改写作主语
6.
they——代词作主语
