在PART 3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. What are the advantages of living in the city?
　　2. What are the disadvantages of keeping a pet?
　　3. What are the advantages and disadvantages of spending time in a foreign country?
　　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：
　　1. What are the advantages of living in the city?
　　In the city you can live a better life because there are a lot of great places to enjoy your life.

　　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, I suppose there are quite a few clear benefits.
　　First, an obvious advantage is that you can enjoy a more colorful life.
　　For example, the subway will bring you a lot of convenience and the shopping malls can add fun to your life.
　　Second, the city can also provide you with better educational resources. You know, the schools are equipped with modern facilities and qualified teachers, which enables you to get a better education.
　　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PART 3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：
　　What are the disadvantages of keeping a pet?
　　Well, certain drawbacks do exist.
　　First, what bothers people most is that it consumes a lot of time and energy. You know, a pet is a vulnerable creature, so you have to look after them all the time and it can be pretty tiring sometimes.
　　Another big downside is that it will add your financial burden. I mean, a decent pet is usually expensive. Plus, you also need to pay for their food and stuff. As a result, your daily expenses will be increased.
　　What are the advantages and disadvantages of spending time in a foreign country?
　　Well, the upside is that you can broaden your horizon. For example, you can visit different places and feel their authentic local culture. Apart from that, you can also pick up a new language. I mean,, if you are in a different country, you’ll have the perfect atmosphere to practice your listening and speaking.
　　However, the downside is that you may feel lonely. I mean, you don’t know anybody and it’s easy to get homesick. Additionally, it will cost you a lot of money. For example, in England, a can of coke is 2 pounds, which equals about 20 yuan.
