The Impact of Air Pollution
The cartoon vividly reveals the phenomenon of air pollution or the decline of air quality. In the cartoon we can see the air pollution is so serious that the earth can't bear it.
What exactly contribute to this phenomenon? Possible reasons can be listed as follows: firstly, vehicle exhaust gases could be one of the most leading causes. With the improvement of economy and people's living standard, urban inhabitants in mounting numbers own their private cars. More automobiles will inevitably generate more exhaust gases. Additionally, household appliances widely used in cities also release a great amount of carbon dioxide gases, which further intensifies air pollution. Last but not least, many factories around the cities emit large quantities of untreated poisonous gases, which should also be responsible for the decline of air quality.
Definitely, air pollution will exert a detrimental impact on many aspects of people's life. For example, many diseases such as cough, skin problem and lung cancer are caused by it. Perhaps it is high time that we should adopt some measures to solve the problem of air pollution.
英语漫画作文写作指导
第一、读图审题
四级漫画作文中的漫画通常反映一个社会现象或生活哲理，要求考生根据自己对漫画的理解来写作。因此，要写好四级漫画作文，审题格外重要。考生在下笔之前要仔细看漫画，弄清漫画的寓意，这是文章切题的保证。此外，在本次四级考试的三道写作题中，Directions部分都给出了写作内容的大致方向，这也为考生把握漫画寓意提供了帮助。下面笔者就来逐一梳理2013年6月四级作文的三幅漫画及其传达的寓意。
第二、谋篇布局
在把握文章的主旨之后，考生就可以构思整篇文章的架构了。四级漫画作文的'写作可以分为下面三个段落。
第一段：开门见山，简要描述一下漫画内容，并指出漫画的寓意。描述漫画内容是为了揭示其中的寓意，是手段而不是目的，所以描述要简洁明快，一般来说一句话足矣。需要提醒考生的是，写作的Directions部分虽然给出了大致的写作主题，但是也要求考生对漫画进行简要描述，因此考生切不可抛开漫画内容直接展开议论。
第二段：表达考生对漫画寓意的看法，这是文章的重心所在。比如，就第一道写作题目而言，考生应在第二段阐述阅读文学作品的重要性;就第二道写作题目而言，考生应在第二段论述为什么凡事必须从小事做起;就第三道写作题目而言，考生应在第二段论述掌握基本技能的重要性。
第三段：指出漫画的寓意对大学生的教育意义，或者提出解决问题的建议。考生需要注意的是，结尾段一般并不需要实质性的分析，其主要作用是总结和升华，使文章结构完整。所以结尾段的写作要简明扼要，点到即止。
第三、论证方法
漫画作文的第二段要表达考生对漫画寓意的看法，这是文章的核心段落，也是作文字数达到要求的关键。因此，考生在这一段要浓墨重彩，写深、写透。在写这一段时，考生要尽量摆事实、讲道理，避免空泛的议论。针对这一核心段落，笔者在此推荐以下三种展开议论的常用方法，希望对考生有所启发。
1.条分缕析
在写作第二段时，考生可以从2～3个方面对观点展开论述，这种写法可使文章显得层次清楚、条理清晰。例如，本次四级作文第一道题目的第二段需要阐述阅读文学作品的重要性，考生就可以从以下两个方面展开：第一，相对于电子媒体，文学阅读更能培养人的想象力;第二，阅读文学作品能够帮助我们更好地了解社会。请参考下面的范文。
There wasa time when children could relish (欣赏/ 也可以使用appreciate 替换) literature. But childrentoday can enjoy the sounds and action on a TV or computer screen. “So why bother reading?” some ask. The reasonis obvious： It enriches our imagination. When we read apiece of literature， we are living the life of RobinHood or starting an adventure with Tom Sawyer. In addition， literature is the mirror of society，whether it be poetry， drama or fiction. We know thesociety better through literature.
2.举例论证
如果漫画所传达的是抽象的人生哲理，那么考生在论述时最好能举出具体的事例，尽量避免空洞的说教。比如，就本次四级作文第二道题目而言，考生可以在第二段中举出一些成功人士如何从小事做起的例子。笔者下面提供的范文中用到的是哈兰·桑德斯上校从一个小吃店做起，最后缔造出遍布全球的肯德基快餐帝国的例子，用以证明只有从小事做起，才能成就大事。请看下面的范文。
Everything is smallbefore it is big. A good example is KFC. In 1930 Colonel Harland Sanders beganserving food to his service station customers in Corbin， a city in Kentucky. He fried chicken in his own kitchen andperfected his secret recipe there. From the small roadside eatery， he went on to build an empire of fast food.
3.类比论证
如果漫画中的寓意不容易通过具体的事例来证明，那么考生还可以使用类比论证的方法，即通过打比方来论证一个抽象的道理。比如，对于本次四级作文的第三道题目，考生可以在第二段中用学习打篮球的过程来打比方。学习打篮球时，只有先学会了投球、运球、传球这些基本技能，才能进一步学习高难度的技能。以此类推，无论做任何事情，只有掌握了基本的技能，才可能取得更大的成功。此外，考生还可以举出统计数字，用具体的研究结果来证明论点。请看下面的范文。
Simple as they mayseem， basic skills serve as the first link in the chain of success. Thisis analogous to learning to play basketball. If shooting， dribbling and passing are not mastered，learning advanced skills will become difficult， if notimpossible. A growing body of research has also documented that such basicskills as reading， writing and computing are highlycorrelated with success later in life. A 2012 study surveyed 300 CEOs ofFortune 500 companies and found that 87% attributed part of their success tothe basic skills they learned in primary school.
