新年第二场考试，是个周四的小考。其实就雅思写作而言，周四的小考和周六的大考并无什么真正的区别。

　　本次考题仍然是近年雅思考试题目的改版，类似的题目在2016年01月30日就出现过，出人意料的是在短短一整年之后这道题又稍微的改头换面再次出现在考场当中。环球教育（原环球教育）杨亮老师为大家解析2017年1月12日雅思高分作文如下。

　　原题如下:

　　Some cities have vehicle-free days when private cars, trucks and motorbikes are banned in city centers. Only public transports like buses, taxis and metros are advised. To what extent do you think the advantages of this outweigh its disadvantages? 20170112

　　城市发展是大作文命题的一个常见范围，其中城市交通是常被涉及的一个小话题。本题需要考生对比私家车定期限行的优缺点。此类的提问方式是较为常见的提问方式的一种。解题框架也比较简单。

　　A growing number of municipal governments begin to formulate regulations to restrain the usage of private vehicles in downtowns in order to ease traffic pressure there. The public, consequently, are concerned about whether some related rules are advantageous or not.

　　开头段用简短的方式介绍背景，之后再引出题目。这种提问方式的点题通常就是简单改写提问句而已。

　　With the number of private cars and urban population both soaring, traffic congestion is one of the most severe problems that urban residents are confronted with in recent years. Driving private cars, admittedly, occupies far more road resources than taking public transports. Restraining private cars and meanwhile promoting public transports are undoubtedly able to reduce traffic congestion. An instance in point is that if 100 people like to travel in the city, what they need is 60 or 80 cars. Instead, 2 or 3 buses can take them wherever they want to go. On top of this, the usage of private cars does contribute substantially to global warming by enhancing carbon emission per person. By contrast, some subway systems and buses are fueled totally by electricity, meaning that taking them is extremely environmentally friendly.

　　主段一，重点阐述限行的好处。从两个方面入手。其一，限行可以使交通畅通。其二可以使人均的碳排放下降。本文采用的是不平均分段的方式，因此这个主段在篇幅上要明显多于下面一个主段。其实，考生也可以将两个优点分别在两个段落中阐明，如此一来全文就是一个五段的文章。

　　Objectors to this issue argue that limiting the use of private cars may cause many city dwellers' giving up their plans of purchasing cars, thus hindering the development of relevant industries. More negative outcomes of this might be an economic downturn and even a higher employment rate. In fact, our governments should never highly value an industry with only focusing on its boosting the economy and creating working opportunities, and on the contrary what it brings to us adversely also deserves attention from both governments and the public.

　　本段为让步段。首先表达了反面观点，即是限行私家车可能带来的消极影响。随后，笔者弱化了这些消极影响。笔者强调政府在考量相关行业发展的同时，不能只强调其优点，也要足够充分地论证其缺点。

　　To sum up, taking public transports is superior to driving private vehicles in places with high density of population.

　　结尾段，极其简短地紧扣主题，再次阐明笔者立场。
