对于备考雅思考试的考生而言，除了剑桥雅思真题系列之外，剑桥雅思官方指南也是很不错的复习资料，充分利用后，考生一定会收获颇丰。今天，前程百利小编想和考生们一起来深入剖析探索雅思大作文之长寿的优劣势，对此观点，考生们有什么看法呢?
今天主要带来的作文是剑桥雅思官方指南Test 2 task2的雅思作文题目，即One of the consequences of improved medical care is that people are living longer and life expectancy is increasing. Do you think the advantages of this development outweigh the disadvantages?
看完此题后，考生们脑海里会有什么想法呢?你认为到底这个想象优势大于劣势，还是劣势大于优势呢?
通过分析，我们得知本题属于社会类，题目类型为讨论类，核心内容讲的是医疗条件的改善使得人们越来越长寿，考官们要进行优劣势分析。考生在进行优劣势分析时，可以在首段交代背景，然后再分段分别讨论优缺点，最后在文章结尾段总结观点并明确给出自己的观点。
在了解了大概的情况以及明确了写作思路之后，我们来逐段进行分析。
第一段：
Over the past 50 years, people have become used to the idea that they will probably live longer than their grandparents did. However, a longer life is only desirable if you can look after yourself and be independent, otherwise there can be disadvantages for everyone.
第一段的第一句话主要交代背景，指出一个社会现象，即人们普遍认为现代人要比以前的人更长寿。第二句话用一个however表示转折，指出长寿可以是好事，但是要在某种前提下才会成立，比如在你能够很好的照顾自己并独立的前提下才会使令人渴望的。同时为下文做铺垫。
become used to意为“习惯于...;适应于...”。
第二段指出人长寿的缺点。
If you walk into a hospital in my country, you are likely to see a lot more elderly people than you did in the past. In fact, this is causing significant problems as there is a shortage of beds. Medical treatment is keeping the elderly alive, but at what cost to others?
人长寿的话就会使老年人不断增加，老龄化现象越来越严重。
本段先用if一词引导假设论证，指出医院中老年人逐渐增多，医疗压力变大，甚至不堪重负，也举例来说明，比如床位空缺，不能提供给更多的人。之后用反问句but at what cost to others来暗示老龄化也会给其他方面造成一定的影响。
medical treatment 医疗
be likely to 有可能..
第三段延续第二段的观点，指出长寿的另一个缺点。
On top of this, one of the biggest medical problems these days is dementia. Even if old people are still fit, they may not be able to look after themselves. They may have to live with their children or be cared for in a home, which can be expensive. Elderly people do not like to be a burden, but their children can feel obliged to care for them.
首句用了短语on top of this来自然地过渡到本段的论述当中，指出医疗难以解决的问题--老年痴呆。本段用例子来证明即使老年人身体健康，如果患有老年痴呆症的话也不能很好照顾自己，这就需要和孩子住在一起或者去养老院接受治疗，但花费将是很昂贵的。虽然老年人不想成为负担， 但是他们的孩子有义务抚养他们。
On top of this 另外;熟练掌握;在...之上;紧接着
dementia n. [内科] 痴呆
obliged adj. 必须的;感激的;有责任的
第四段主要阐述的是长寿的好处。
Obviously, not all old people become ill. Those who remain healthy can enjoy a happy old age as long as they have saved enough money. People are more active in their sixties and seventies than they used to be and this can only be a good thing. They have time to enjoy their retirement and do a range of activities that they could not do when they were at work. They can also help look after their grandchildren, which is a great benefit for working parents.
本段通过一个词Obviously来表明让步，即不是所有老年人都有健康问题，只要有足够的积蓄，老年人还是可以保持健康并享受生活。接下来用举例证明，在他们退休后，他们会很享受退休以后的生活、做一些在工作中无法做到的是事情或是活动。他们也有精力帮忙照顾子孙，这就大大减轻了父母的负担。
第五段总结。
To sum up, I believe that we should aim to keep people as healthy as possible so that they can enjoy their old age without having to rely on others. A longer life expectancy is obviously advantageous, but no one wants to live to be 100 if they only cause problems for their family and society.
本段首先用I believe that we should aim to…表明老年人只有保持健康，才能不依赖别人从而更好地享受晚年生活。然后针对题目中的核心内容，指出长寿不给家人和社会带来问题的话，是好事，反之，没人会想活到100岁。
aim to vt. 计划，打算;目标在于...
life expectancy 预期寿命，平均寿命
在分析文章之后，我们可以看出吗文章在论述的时候运用的论证方法主要有假设论证、举例论证、让步论证等来进行阐述，使得文章的论据更加丰富，有理有据。
下面给出相应范文，可供参考学习。
