备考雅思写作考试，考生不仅要有方法技巧，从优秀范文中去吸取精华之处，并为之所用一定会有很大的收获。下面，就和前程百利小编一起来学习雅思社会类大作文之人口增长原因分析，希望考生能够认真参考。
本次所要讲解的是大作文来源于剑桥雅思官方指南中Test 6 Task 2，作文题目为The continued rise in the world’s population is the greatest problem faced by humanity at the present time. What are the causes of this continued rise? Do you agree that it is the greatest problem faced by humanity?
从题目中可以看出，该题题材为社会类，题目类型为讨论类。题中有一个观点，即不断增长的人口数量是人类目前为止面临的最大问题;也有两个问题需要考生去解决，一是考生要分析增长的原因，二是考生是否同意该观点。针对题目中所给观点，考生要进行分析其原因并给出自己的见解。
分析之后，我们可以进行段落布局，文章整体要怎样写才好呢?其实，我们可以这样，既然题目让我们分析人口增长的原因，那么，我们就在主体段进行原因分析，然后给出自己的观点，文章首段与结尾段照常写。至于主体段的原因分为几个段落，考生要恰当布局，不能过多也不能过少。
下面，我们就赶紧来分析一下范文是如何进行写作，又有什么值得借鉴之处吧!
首段：话题讨论，引出下文。
原文：
As members in the metropolis, most of us have had enough of the troubles that caused by the continued rise in the world' population. What factors lead to these phenomena and what impacts it may bring have become a concern to many people. From my point of view, the following reasons should be taken into considerations.
词汇：
metropolis 大都市
参考译文：
作为大都市的成员，我们大都已经受够了世界人口增长带来的是麻烦。很多人会关心，是什么因素导致了这些现象，这又会带来什么影响。在我看来，应该考虑到以下原因。
第二段：介绍人口增长的其中一个原因，即当前稳定的经济环境。
To begin with, the current stable economic circumstance is a great influential factor. Social and economic circumstance has a dramatic effect on people's living condition.
数据论证：
原文：
According to an international survey, more than 50 percent couples in the world are able and willing to raise more children, which will probably lead to a new wave of population explosion.
词汇：
To begin with首先，本来
参考译文：
目前稳定的经济环境是最大的影响因素。社会和经济条件对人们生活水平有惊人的影响。根据一项国际调查，超过百分之五十的夫妻有能力也有意愿去养育更多的孩子，这可能会导致新一轮的人口爆炸。
第三段：介绍人口增长的另外一个原因，即不断提高的国际医疗水平。
原文：
Of equal importance is the rapidly developing national medical care system. Development of modern technology has always been amazing.
举例论证：
Certain diseases such as tuberculosis and dysentery are now easy to remedy with low expense, but in the past they are all probably lethal. It is hard to imagine that an individual who lived in the past might even die of a toothache. Dental technology seems developed little except its exorbitantly charged bill, however, our surprise, the simplest technique contributes to people's longevity most.
词汇：
Of equal importance is 与…同等重要的是
tuberculosis 肺结核
dysentery 痢疾
remedy vt. 补救;治疗;纠正
lethal adj. 致命的，致死的
exorbitantly adv. 过高地;过度地
参考译文：
国际医疗保健系统的迅速大战是同等重要的因素。现代科技的发展总是令人惊讶的，像肺结核和痢疾等某些疾病，现在不用花费很多就能轻松治好，但是在过去，这些可能是致命的。很难想象过去的人会死于牙疼。除了价格，牙科技术似乎提高的很少，然而令我们吃惊的是，这最单穿的技术对人类寿命的贡献最大。
第四段：给出自己的观点，即表示赞同，认为人口问题是人类面临的最大问题。
原文：
Doubtlessly, the population problem can be regarded as one of the most serious issues faced by humanity.
举例论证：
It may bring about many unexpected crises, like the employment problem and the aging problem, which are not only the stumbling blocks for the future development of the society, but also the pressures for resources carrying capacity.
词汇：
bring about 引起
unexpected 意外的，想不到的
stumbling blocks 绊脚石
resources carrying capacity 资源承载力
参考译文：
人口问题可能引起很多意想不到的危机，比如就业问题，老龄化问题，不仅能成为社会发展的绊脚石，也会给资源承载力带来压力。
结尾段：总结全文。
原文：
All in all, although the problem of increasing population may seem difficult to eliminate, there are concrete steps that can be taken to control that worldwide. The negative effects from this problem are too great to ignore.
词汇：
eliminate vt. 消除;排除
concrete adj. 实在的，具体的
参考译文：
人口增长似乎很难消除，仍然需要具体措施来解决，在世界范围内控制。这个问题的负面影响很大，不容忽视。
总结：
本文在论述时恰当应用数据论证以及举例论证等论证方法，并在语言使用方面，词汇更加专业，高级，句式更多样，让文章在表达上更紧密，连贯。
