范文一Directions:Write a composition entitled Cars and Air Pollution. You should write at least 120 words according to the outline given below in Chinese.1.汽车越来越多，造成了城市的空气污染；2.如何解决这一问题；3.做出总结。
【步骤构思】步骤1：审题：这是一篇以汽车和空气污染为主题的解释说明文。
步骤2：引入话题：越来越多的汽车造成城市空气污染；展开话题：从两方面说明解决这一问题的办法；话题结论：大家共同努力，消除汽车造成的空气污染。
【作文背诵范文】Cars and Air PollutionToo many cars have created a lot of serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. All the time，they are releasing huge amounts of waste gases into the atmosphere. These gases are very harmful, causing diseases and even death.太多的汽车已经给我们的世界制造了许多严重的问题。
除了堵车、事故和快速的燃料消耗之外，汽车对大城市的空气污染有很大一部分责任。
一直以来，汽车向大气中释放大量的废气。
这些气体非常有害，会导致疾病甚至死亡。
So serious is the problem that we must find some solutions to it. One possible solution is to design and develop clean cars and clean fuels. In Shanghai, some of the public buses begin to run on natural gas， which does not give off as much carbon dioxide as petrol. But it may take decades for the new models of clean cars to complete1y replace the traditionalones. Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and environment enough, most people will not buy private cars. And the total number of cars in big cities will reduce greatly.问题如此严峻，我们必须找到一些解决方法。

下面是文都四级小编为大家整理的说明文写作方法与万能模板，希望对大家有帮助。
什么是说明文？说明文是以说明为主要表达方式用来说明事物，阐明事理的一种文体。
它通过揭示概念来说明事物的特征、本质及其规律性，给人准确的科学知识或正确思想。
一般可分为实体事物说明和抽象事物说明两大类，词典、教材、论文、实验报告、产品说明书、广告、解说词及科学小品等都属于说明文。
说明文的写法有哪些？按写作方法,英语说明文主要分为六种类型：1.例证法这是用具体例子来说明人或事物的特征、本质及其规律的方法,所用例子必须有代表性、典型性,能体现人或事物的本质特征。
这是用特殊来说明一般的方法。
通常在主题句后,用For example 或For instance 等短语引导出具体的例子。
例如:Our life today depends very much on energy. For example, machines have made our life easier than it used to be. The machines use energy, and energy is needed for heating, lighting, communications, carrying goods-everything.Factories use a great deal of energy to make the things that we use and buy and sell.这段主要是讲能源问题。
第一句为主题句,概括地说出"我们目前的生活很大程度上依赖能源"。
接着用举例的方法从三方面说明能源的作用。
2.定义法下定义就是给说明对象一个明确概念。
这是科学而严密的说明方法。

英语四级作文写作思路及练习：说明文说明文是用言简意赅的语言来介绍客观事物，讲清事理，并给人增加知识的一种文体。
说明文解说事物的特点、发展变化规律，分析前因后果，目的在于使读者“明白事理”，获得必要的信息，对事物有个较完整明晰的了解和认识。
说明文不同于记叙文和议论文，它重在给人介绍，让人明白，因而，轻“情义”重事实。
说明文与议论文关系密切，有人将其统称为议论文。
但在写作的目的和方法上两者仍有区别。
说明文主要是通过事实客观地解释或说明事物本身;而议论文则以事实、数据等为证据，表明主观见解，使读者信服或赞同某一观点。
历年四级考试中的“How I Overcome Difficulties in Learning English”、“My Ideal Job”以及图表作文的第一段都属于说明文的范畴，如，2002年6月的根据坐标图写题为“Students Use of Computers”的作文。
说明文必须按一定的顺序进行说明：时间顺序、空间顺序、逻辑顺序或认识顺序，选择具体的特点和细节来说明。
所以，说明文的思路要围绕说明顺序、事物的特点和细节展开。
例如：范文点评A Famous ClockWhen you visit London, one of the first things you will see is Big Ben, the famous clock which can be heard all over the world on the B.B.C. If the Houses of Parliament had not been burned down in 1834, the great clock would never have been erected. Big Ben takes its name from Sir Benjamin Hall who was responsible for the making of the clock when the new Houses of Parliament were being built. It is not only of immense size, but is extremely accurate as well. Officials from Greenwich Observatory have the clock checked twice a day. On the B.B.C. you can hear the clock when it is actually striking because microphones are connected to the clock tower. Big Ben has rarely gone wrong. Once, however, it failed to give the correct time.A painter who had been working on the tower hung a pot of paint on one of the hands and slowed it down!【点评】这是《新概念英语》中的一篇经典说明文，介绍了世界著名的“大本钟”。
文章开篇指明该钟位于英国伦敦，且全世界的人们通过BBC就能够听到钟声。
接下来讲述了“大本钟”的由来，培训搜px.wangxiao.so培训网提示您:特点——不仅外型巨大，而且走时准确，在结尾处讲了“大本钟”的一个幽默的小插曲——油漆工把油漆桶挂在指针上，把钟弄慢了。
细读这篇文章，我们不难发现，区区159个单词就把“大本钟”的光辉形象牢牢地刻在读者的脑海里，中小学辅导网wangxiao.so提示您:为什么?本文基于事实，分析了主题的来龙去脉，语言简洁又不失生动贴切，作者态度客观又充满幽默，使读者既“明白了事理”，又对事物有较完整明晰的了解认识，此乃说明文之真谛也。
以“Goals”为题打开一篇说明文的思路。
参考思路1)目标的分类：(可根据时间顺序，空间顺序、逻辑顺序或认识顺序，任选一个进行分类和排列)2)各个类别的特点和细节：3)组织成文：范文点评GoalsEveryone has goals. Many people do not reach their goals for lack of planning. These three sets of goals should be developed: lifetime, intermediate and short term.Lifetime goals should be written out. These goals should be clear and reasonable. For instance, the goal to win a research prize is clear and measurable. Other lifetime goals might include publishing a certain number of influential books or articles, earning a departmental chairmanship at a major university, successfully competing for a grant from the National Science Foundation or securing a consultantship with a big corporation.Intermediate goals relate to outcomes during the next few years. For the beginning doctoral student, intermediate goals may include completion of course work and preparation of a doctoral research proposal. Like lifetime goals, these are measurable and clearly stated.Short-term goals involve outcomes expected during the next 12 months. These goals are more performance oriented, and they help with achievement of intermediate goals. Examples of short-term goals are earning an A in a course, learning how to program a computer or performing an experiment.说明文的说明方法对这些方法我们要了解并且掌握：1. 定义法(definition)定义法是用下定义的方式去揭示事物本质特征或概念内涵。
它能使读者迅速抓住本质属性和基本特点。
此法的句型：①… is a/the … of … which/that …②… relate to/involve/refer to …【例】(1)Language is a system of arbitrary vocal symbols which is used for human communication. 语言是人类用来交际的任意性的语音符号体系。
(2)Intermediate goals relate to outcomes during the next few years.(3)Short-term goals involve outcomes expected during the next 12 months.2. 举例法(illustration)举例法就是举出实际事例来说明事物的方法，是最常见，往往也是最有效的阐释模式。
专家提醒举例时应挑选具体、典型且有能力表达清楚的例子，并注意按照一定的顺序编排。
请看上述范文第二段：“For instance”引出“lifetime goals”的实例，如，赢得研究奖金、出版有影响书或文章、获得大学的系主任职位、获得国家自然科学基金及大公司稳定的顾问职位。
3. 分类法(classification)分类法就是把说明的对象，按一定的标准划分成不同类别分别加以说明的方法。
如：上述范文介绍人生的三种目标，并按照时间的长短对终生目标、长期目标和短期目标做了分类说明。
4. 比较法(comparison)比较法是用一个事物和与其有联系的其他事物加以对比的说明方法。
目的是为了帮助读者准确地区分事物，通过对比达到对该事物的深刻认识。
如：上述范文对三种人生目标在时间上和实际操作上进行了比较，并阐明了彼此的联系。
(1)Lifetime goals should be written out.(2)Like lifetime goals, these are measurable and clearly stated.(3)These goals are more performance oriented, and they help with achievement of intermediate goals.5. 数字法(statistics)数字法是运用数据来表明事物的本质和特点，准确合理的数据使文章精确可信。
【例】(1)Nearly half of all Americans over age 20 wear a bridge or denture，and more than 20 percent have complete upper and lower denture. By age 50, one out of every two persons has gum disease.(2)And it seems sensible to wait. One quarter of all marriages between people under twenty-one end in divorce. In Britain in 1972, there were 124,248 divorces.说明文的说明方法除上面介绍的常见的几种以外，还有诸如分项法、列举法、比喻法及引用法等，只有综合运用多种说明方法，才能多角度、多层次地全面、清晰、准确地展示客观事物的本来面貌。
