在PART3中，好坏类类的题目出现的频率非常高，这一类题目很多学生是有话可说的，但是问题在于好处或者坏处只能想到一点，所以答案内容往往比较单一，让人苦恼，下面我们就来跟着新东方在线闫春伟老师来学习好坏类考题的答题技巧。
首先我们来看一下国家类问题的提问方式：
1.Whataretheadvantagesoflivinginthecity
2.Whatarethedisadvantagesofkeepingapet
3.Whataretheadvantagesanddisadvantagesofspendingtimeinaforeigncountry？
同学们应该看出来了，问题问的全都是“advantage”或者“disadvantage”。有的题目单方面问好处或者坏处，有的题目把好处和坏处合在一起问。
下面我们再来看一位中国考生的答案：
Inthecityyoucanliveabetterlifebecausetherearealotofgreatplacestoenjoyyourlife.
相信同学们都能看出来这个答案不是太好，比较短，太宽泛了，那么我们到底应该怎么回答呢？请看下边这个样本：
Well,Isupposetherearequiteafewclearbenefits.
First,anobviousadvantageisthatyoucanenjoyamorecolorfullife.
Forexample,thesubwaywillbringyoualotofconvenienceandtheshoppingmallscanaddfuntoyourlife.
Second,thecitycanalsoprovideyouwithbettereducationalresources.Youknow,theschoolsareequippedwithmodernfacilitiesandqualifiedteachers,whichenablesyoutogetabettereducation.
同学们应该看出来了，我除了从“生活”角度进行了分析，还从“教育资源”角度进行了分析。其实这就是我要教给各位同学的“对应式思考”。对于PART3的问题，如果我们只有一个中心点，那么可以从这个中心点的对应面出发，寻找第二个中心点，来扩充语言。例如：生活VS学习，物质VS精神，个人VS社会等等。
下面我再给同学们举两个具体的例子，供同学们参考：
