雅思climate change 对于事业的影响

今晚雅思作文考试准备：

一、小作文（ 流程图、柱状图、表格、饼图、地图、混合图、线图 ）

备考建议： 反复看范文，多练习 。看到题目，先想怎么 归纳信息 ，段落层次的归纳和句子层次的归纳（可以写出来）；然后去看范文，和自己之前写的做对比，看看欠缺在哪里（比如没有意识到可以将六种能源归成化石能源和可再生能源两大类）；把范文多看几遍以后，尝试去默写！但是不要去背范文，背下来就失去效果了。  多看几遍，尝试记住范文是怎么归纳信息的，然后自己 默写 ，写好之后再去和范文对比，看看哪些表达方式忘掉了，哪些信息归纳方式忘掉了，把它们记下来。

二、大作文

备考建议：一篇雅思考官9分范文至少读2-4遍。

第一遍： 1）读懂内容意思；2）勾画出：生词，好词，重点词汇，同义词替换；3）勾画出好句；4）了解文章的：结构，总论点。

第二三四遍： 1）细致分析主体段的论证过程，包括：分论点是什么，论据是什么，使用了什么样的论证方法。2）拆分论证逻辑。3）读的过程中留意承接上文部分以及首尾呼应等写作手法。

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。

Dear Judy,Your mother are very worried about you now.I must give you some advice,or you wilI bee worse.First,I think you don't need to care about your weight so much.There are a lot of fat people in the world,but they can still bee great people. Second,being thinner is really a stupid thing for a young girl.It will waste you a lot of time.As the saying goes,＂time is money＂.If the time goes,it will never e back.Stop losing your weight and try doing some other important things,such as reading books,talking with your friends and so on. Finally,the most important thing is that you should think about your mother.As we all know the maternal love is a greatest power of world. Mother gived you too much and she loved you too much,so don't make your mother feel worried. I am looking forward to hearing from you.yours Editor

08四川 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. Sample 3: William Shakespeare Do you know Hamlet? Have you read the Merchant of Venice? ...

20x×年的一天，我漫步在公路旁。只见，公路两旁载满了挺拔的大树，公路上行驶的汽车都是用混合燃料发动的，不像以前那种汽油型的汽车开起来既要燃油，又污染空气。工厂和居民的用电也是用风能、太阳能、开发垃圾回收来发电。全都是一个崭新的能源利用法展现在我们的眼前。“能源”一个醒目的词语，“跳动”在我们的眼帘。你会想到什么呢？你可能会说“能源”这个词说熟悉，我不知道怎么说好。说不熟悉吧，我们生活中处处都有能源。那就让我们来聊一聊能源这个话题吧！

地球是在一次宇宙爆炸中炸出来的，它一炸出来就内涵丰富的能源。化工燃料、太阳能、核能、水能、石油、生物燃料等等……说了这么多，那到底什么是能源呢？能源就是能产生能量的物质。能源种类有很多：有一次能源、有二次能源、有可再生能源、还有非再生能源。一次能源是直接来自自然界未经加工转换的能源，此类能源有：化石燃料、太阳能、核能、生物燃料、水能等等……二次能源是由一次能源直接或间接转化而来的能源，此类能源有：电能、煤气、汽油、沼气、氢能等等……可再生能源是不随其本身的转化或被人类利用而减少的能源，此类能源有：太阳能、风能、地热能等等……非再生能源是随其本身的转化或被人类利用减少的能源，此类能源有：化石燃料、核燃料等等……打个比方吧，我们以前生活常见的传统能源它们有：原煤、天然气、汽油、煤油、热力、电力、石油气、柴油等等……还有许许多多的工程都用到了能源比如：三峡大坝和葛洲坝用水能、火箭发射升空用氢燃料、秦山核电站用原子能发电。大量的能源使用使我们成为了“石油”能源的“俘虏”，而我们现在在节约能源的基础上，开发了新的能源。摆脱了石油能源的依赖性，首先一利用风能和太阳能发电取消电网送电。再利用混合燃料发动汽车、利用氢能源的开发、利用生物来直接将太阳转化为氢、利用海浪发电、开发垃圾燃气来开发能源市场，使我们能更有效的开创能源的利用和起到环保的作用有利于生态环境。人类早就千方百计地从太阳能、水能、风能、生物能中寻找新的替代能源。这些能源都很重要，但专家们认为，它们都有自身的局限性。太阳能的能流密度太低，随昼夜、晴雨、季节的变化很大，难以成为大规模的工业能源，只能满足家庭以及一些特殊需要；水能增长的速度跟不上能耗增长速度，并对生态、生物链产生难以估量的影响；风能、地热能、潮汐能的资源和利用也各有局限，在未来的能源开发中作用不大；生物能倒是一种可以大规模使用的再生能源，但再生速度也难以赶不能源消耗增长的需要。

听了我对这能源新旧对比的介绍，你是不是对能源更加了解，更加有兴趣去开发，那让我们更多的有志之士来合理地去开发能源，使我们子孙后代受益无穷

随着科学技术的发展，关于开发利用月球上的氦-3的种种设想一定会越来越丰富多彩，越来越详尽具体，越来越接近最终的实践，绝对不会是纸上谈兵或空中楼阁。而且，在月球上建立能源基地不仅仅是开发利用氦-3，月球上的太阳能也有很广阔的开发利用前景。

月球上的太阳能是极为丰富的，因为没有大气层的影响，太阳辐射可以长躯直入，每年到达月球范围的太阳光辐射能量高达12万亿千瓦，相当于目前地球上一年消耗的各种能源所产生的总能量的2.5万倍。采用目前非常成熟的光电转换技术，在月球上进行太阳能发电是比较容易的，而且不必担心土地的占用，在月球上可以无限制地铺设太阳能电池板。

许多专家对在月球上利用太阳能发电都有十分浓厚的兴趣。专家们测算，如果用光电转化率为20%的太阳能发电装置，每平方米太阳电池每小时可发电2.7千瓦时，若采用1000平方米的电池，则每小时可产生2700千瓦时的电能。这些电能同样可以通过激光或微波输送到中继卫星，再传送到地球电力接收站，直至送到全球各地用户。

考虑到月球上白天和黑夜都相当于14个地球日，太阳能发电厂可优先建造在太阳光照时间较长的两极地区。随着月球基地建设的发展，还可以通盘考太阳能发电厂的布局，有的建造在月球的正面，有的建造在月球的背面，形成全球性的并联式太阳能发电厂，太阳能发电厂与核电厂还可以实行联网。这样不仅可以平稳充足地供应月球基地用电，也可以平稳充足地向地球送电。

在可以想象的未来，由氦-3采掘加工厂、核发电厂和太阳能发电厂组成的月球能源基地，不仅可以为月球的长夜带来光明，为月球的开发利用带来强大的动力，也可以为地球的能源接替做出无可估量的贡献，为人类飞向火星等其他星球加油增力。

试看将来的月球，绝不仅仅是供人类欣赏的“冰轮”，而是一个可以推动整个宇宙开发利用的强有力的巨轮！

太阳能

太阳能一般指太阳光的辐射能量。太阳能的主要利用形式有太阳能的光热转换、光电转换以及光化学转换三种主要方式

广义上的太阳能是地球上许多能量的来源，如风能，化学能，水的势能等由太阳能导致或转化成的能量形式。

利用太阳能的方法主要有：太阳电能池，通过光电转换把太阳光中包含的能量转化为电能；太阳能热水器，利用太阳光的热量加热水，并利用热水发电等。

太阳能可分为2种：

1.太阳能光伏 光伏板组件是一种暴露在阳光下便会产生直流电的发电装置，由几乎全部以半导体物料(例如硅)制成的薄身固体光伏电池组成。由于没有活动的部分，故可以长时间操作而不会导致任何损耗。简单的光伏电池可为手表及计算机提供能源，较复杂的光伏系统可为房屋照明，并为电网供电。 光伏板组件可以制成不同形状，而组件又可连接，以产生更多电力。近年，天台及建筑物表面均会使用光伏板组件，甚至被用作窗户、天窗或遮蔽装置的一部分，这些光伏设施通常被称为附设于建筑物的光伏系统。

2.太阳热能 现代的太阳热能科技将阳光聚合，并运用其能量产生热水、蒸气和电力。除了运用适当的科技来收集太阳能外，建筑物亦可利用太阳的光和热能，方法是在设计时加入合适的装备，例如巨型的向南窗户或使用能吸收及慢慢释放太阳热力的建筑材料。

核能

核能是通过转化其质量从原子核释放的能量，符合阿尔伯特·爱因斯坦的方程E=mc^2，其中E=能量，m=质量，c=光速常量。核能的释放主要有三种形式：

A.核裂变能

所谓核裂变能是通过一些重原子核（如铀-235、铀-238、钚-239等）的裂变释放出的能量

B.核聚变能

由两个或两个以上氢原子核（如氢的同位素—氘和氚）结合成一个较重的原子核，同时发生质量亏损释放出巨大能量的反应叫做核聚变反应，其释放出的能量称为核聚变能。

C.核衰变

核衰变是一种自然的慢得多的裂变形式，因其能量释放缓慢而难以加以利用

核能的利用存在的主要问题：

（1）资源利用率低

（2）反应后产生的核废料成为危害生物圈的潜在因素，其最终处理技术尚未完全解决

（3）反应堆的安全问题尚需不断监控及改进

（4）核不扩散要求的约束，即核电站反应堆中生成的钚-239受控制

（5）核电建设投资费用仍然比常规能源发电高，投资风险较大

海洋能

海洋能指蕴藏于海水中的各种可再生能源，包括潮汐能、波浪能、海流能、海水温差能、海水盐度差能等。这些能源都具有可再生性和不污染环境等优点，是一项亟待开发利用的具有战略意义的新能源。

波浪发电，据科学家推算，地球上波浪蕴藏的电能高达90万亿度。目前，海上导航浮标和灯塔已经用上了波浪发电机发出的电来照明。大型波浪发电机组也已问世。我国在也对波浪发电进行研究和试验，并制成了供航标灯使用的发电装置。

潮汐发电，据世界动力会议估计，到2020年，全世界潮汐发电量将达到1000-3000亿千瓦。世界上最大的潮汐发电站是法国北部英吉利海峡上的朗斯河口电站，发电能力24万千瓦，已经工作了30多年。我国在浙江省建造了江厦潮汐电站，总容量达到3000千瓦。

风能

风能是太阳辐射下流动所形成的。风能与其他能源相比，具有明显的优势，它蕴藏量大，是水能的10倍，分布广泛，永不枯竭，对交通不便、远离主干电网的岛屿及边远地区尤为重要。

风力发电，是当代人利用风能最常见的形式，自19世纪末，丹麦研制成风力发电机以来，人们认识到石油等能源会枯竭，才重视风能的发展。

1977年，联邦德国在著名的风谷--石勒苏益格-荷尔斯泰因州的布隆坡特尔建造了一个世界上最大的发电风车。该风车高150米，每个浆叶长40米，重18吨，用玻璃钢制成。到1994年，全世界的风力发电机装机容量已达到300万千瓦左右，每年发电约50亿千瓦时。

生物质能

生物质能来源于生物质，也是太阳能以化学能形式贮存于生物中的一种能量形式，它直接或间接地来源于植物的光合作用。生物质能是贮存的太阳能，更是一种唯一可再生的碳源，可转化成常规的固态、液态或气态的燃料。地球上的生物质能资源较为丰富，而且是一种无害的能源。地球每年经光合作用产生的物质有1730亿吨，其中蕴含的能量相当于全世界能源消耗总量的10-20倍，但目前的利用率不到3%。

地热能

地球内部热源可来自重力分异、潮汐磨擦、化学反应和放射性元素衰变释放的能量等。放射性热能是地球主要热源。我国地热资源丰富，分布广泛，已有5500处地热点，地热田45个，地热资源总量约320万兆瓦。

氢能

在众多新能源中，氢能以其重量轻、无污染、热值高、应用面广等独特优点脱颖而出，将成为21世纪的理想能源。氢能可以作飞机、汽车的燃料，可以用作推动火箭动力。

海洋渗透能

如果有两种盐溶液，一种溶液中盐的浓度高，一种溶液的浓度低，那么把两种溶液放在一起并用一种渗透膜隔离后，会产生渗透压，水会从浓度低的溶液流向浓度高的溶液。江河里流动的是淡水，而海洋中存在的是咸水，两者也存在一定的浓度差。在江河的入海口，淡水的水压比海水的水压高，如果在入海口放置一个涡轮发电机，淡水和海水之间的渗透压就可以推动涡轮机来发电。

海洋渗透能是一种十分环保的绿色能源，它既不产生垃圾，也没有二氧化碳的排放，更不依赖天气的状况，可以说是取之不尽，用之不竭。而在盐分浓度更大的水域里，渗透发电厂的发电效能会更好，比如地中海、死海、我国盐城市的大盐湖、美国的大盐湖。当然发电厂附近必须有淡水的供给。据挪威能源集团的负责人巴德·米克尔森估计，利用海洋渗透能发电，全球范围内年度发电量可以达到16000亿度。

水是生命之源，节水不容忽视！

虽然自然界里水会循环，但是，人类的用水量远高于可以让人类运用的水，节约用水就成了我们每个人

都应该做的事情。

我觉得，已用过的水和已经遭受污染的水都可以再次利用。例如，洗菜、洗衣服的水可以冲马桶，受过污染的水可以在一切能够利用的情况多多利用，这样不仅减少了水费，更做到了节约用水的目的。而城市污水应多多回用于公用设施和住宅冲洗厕所、浇灌绿地、景观用水, 浇洒道路等, 这样做，污水的循环作用就提高了不少！

你知道吗？地球上有70.9%都是水,可这些水中有97.47%是咸水,咸水大部分是海洋水,不能饮用,因为1KG海洋水中就有39G个盐类物质；而这些水中的2.53%是淡水,而淡水大多是冰川水和深层地下水,这两种水占淡水的99%,可供我们人类使用的水仅占淡水的0.3%,我们的水资源十分少。我国是个缺水的国家，因此，我们更要节约用水，保护水资源。

水资源的利用在生活中是无所不在的，工厂排放出的污水再经过净化后同样可以循环使用，但是，也是要付出代价的，例如净化的成本，而这些又需要消耗资源。

雨水是我们每个人都见过的吧。当然，你有没有想到利用雨水就很难说了。科学家们都认为，雨水其实是一种难得的财富，它也是水资源，而且相当宝贵，但是，从全国范围看，我国的雨水收集与利用率还很低，我们应该用科学发展的思维看待雨水，用科学手段对待雨水，让雨水留下来，被我们科学地、循环地加以利用后，再科学地送它或入地或入河湖而去。这样何尝不是一种充分利用水资源的方法呢？

其实，水的宝贵大多数人都知道，却也选择遗忘。多少人不知道该如何节约用水？多少人浪费水资源？恐怕多得很吧。这就跟宣传有关了，我想，电视方面应该多多播放关于资源利用的问题，政府的宣传也是相当重要的，而新时代的祖国花朵们，更应该在从小就养成节约用水的好习惯，要知道，我们人类，离不开水，整个地球，离不开水！

况且节水有很多好处，不仅有利于缓解水资源的供需矛盾，减轻城市发展对环境的压力，还有利于延续供水和污水处理设施的建设投资，降低供水和污水处理设施的运行成本。从战略角度来看，节水绝对百益而一害！

节约用水靠得不是一个人的努力，是千千万万的人的努力，但不管用什么办法，我们都应该立即行动起来，把理念化为行动，要知道，水在日渐地减少，节水行动刻不容缓！

未来的能源

现在，每个国家都需要能源。瞧，有的国家为能源在争吵，有的国家为能源随时准备战争，想用武力掠夺能源（如伊拉克与科威特的战争，印度尼西亚与马来西亚的海上领土纠纷）。可见，能源是多么重要，因为我们现在用的电大部分就是以煤作为能源开发利用的；在大街上跑的汽车绝大部分是以汽油或柴油为动力的，而汽油和柴油是以地下开采的石油提炼出来的；在家里煮饭大部分用的是煤气与天然气。

据说，石油、煤、天然气的开采和使用都会不同程度地污染环境哟！

那么，如果哪一天地下的石油、煤、天然气都开采完了，怎么办？也许，用不着100年，地球上的地下能源就会枯竭。到那时，因为没有电，电视机开不了、空调无法启动、电脑成废物、甚至到晚上连电灯也无法开亮；因为没有石油和煤的资源，飞机、火车、轮船、汽车通通都开不动了。这样一来，我们就只能坐马车或骑自行车去学校上课啦，而且晚上大街和家里都是一片漆黑，晚上在家做作业就只能烧柴火来照明了。哗！那太可怕啦？！

据说，还有一种能源是用水来发电的，但是开发水电要拦截河流，而且会影响地球上的生态平衡哟！

我不希望看到世界上有争吵与战争，我希望世界上充满欢乐与和平。所以我幻想要是每家每户都有一个“微型能源器”该多好。这个能源器不需要我们去破坏地下资源，可以随时吸收储藏太阳能、风能等所有大自然的自然能源（如果让它放在海边，还可以随时

吸收储藏潮汐产生的动能……），需要用能源时可以随时随地释放出来供大家使用，如果需要用很大的能源动力时（如飞机、火车、轮船）可以用很多很多的“微型能源器”相互组合来提供能源。这样一来，有了这种“微型能源器”，世界上每个国家之间也许不会再争吵、不会再发动战争了；而且肯定不会造成环境污染，也不会破坏生态平衡；同时，可以美化我们的城市，因为我们可以不需要大街上那些难看的电线杆、电线塔及缠绕在上面象蜘蛛网一样的电缆线；还有，这种“微型能源器”，不需要进行高压变电，可以彻底消除因电磁波产生辐射给人类造成的健康损害。

也许在不久的将来，“微型能源器”便会出现，带给人类和平、健康和快乐！
