雅思大作文开头怎么写？
虽说“好的开始是成功的一半”在雅思写作上并不适用，但是熟练掌握开头段的写作方法无疑可以节省考场时间，提高主体段写作效率。
今天，小编搬运并汇总整理前考官Simon对雅思大作文开头段写作方式的建议，并结合个人学习体会，和大家说说大作文开头段该怎么写。
基本原则：
开头段的内容，来自原题和自己的观点。审好题并确定自己观点后，可以着手写开头段。
1.两句话。一句介绍话题，一句给出概括观点及原因或预告全文内容。
2.要提到问题中的所有内容。
3.如果题目要求给出你的观点，在开头段就写出来。
语言简洁准确即可，把更多时间和精力用于主体段。
题型分类：针对不同的题型和问题，开头段的具体写作方式有所区别。下面结合例题和例文来具体说明。
一、Report类
Report类题目的开头段相对简单，只需要改写题目介绍背景+概述全文内容。
例1：The number of plants and animals is declining. Describe some reasons for this problem and suggest some solutions.
开头段：It is undeniable that wildlife habitats are being destroyed and whole species of plants and animals are disappearing. There are several causes of this alarming trend, but measures could certainly be taken to tackle the problem.
解析：第一句改写题目，用whole species of plants and animals对应/替换plants and animals，用are disappearing 对应is declining，提到了题中所有内容并用“栖息地被破坏”进行了背景拓展。第二句直接回应题目要求，有原因，有办法。
例2：In the developed world, average life expectancy is increasing. What problems will this cause for individuals and society? Suggest some measures that could be taken to reduce the impact of ageing populations.
开头段：It is true that people inindustrialised nations can expect to live longer than ever before. Although there will undoubtedly be some negative consequences of this trend, societies can take steps to mitigate these potential problems.
解析：第一句改写题目，用It is句型引出事实，用industrialised nations对应in teh developed world，用expect to live longer thant before对应average life expectancy is increasing，回应题中所有内容。第二句用Although使句子更紧凑，回应了任务要求，negative consequences对应problems，measures对应steps，mitigate these potential problems对应reduce the impact of .
二、DG类
DG类的题目，在个人观点上有两种可能：一是A和B都有道理/都重要/对实现某一目标都有作用，二是A或B更有道理/更重要/更好。相应的开头段写法如下：
1.人们对某事的看法不同+我觉得都需要。
例1：Some people think that museums should be enjoyable places to entertain people, while others believe that the purpose of museums is to educate.Discuss both views and give your own opinion.
开头段：People have different views about the role and function of museums. In my opinion, museums can and should be both entertaining and educational.
解析：第一句用套句开头，但对原题内容进行了改写和概括，本文用the role and function替换了原文的the purpose。第二句概括给出自己的观点，两者可以共存.
例2：Some people think that strict punishments for driving offences are the key to reducing traffic accidents. Others, however, believe that other measures would be more effective in improving road safety. Discuss both these views and give your own opinion.
开头段：People have differing views with regard to the question of how to make our roads safer. In my view, both punishments and a range of other measures can be used together to promote better driving habits.
组长解析：第一句用套句开头，并对有争议的问题进行了概括，用how to make our roads safer替换原文的reducing traffic accidents和improving road safety。第二句概括给出自己的观点，两种观点都能发挥作用。
2.改写题目(事实背景)+虽然A有道理，但我更倾向B。
例1：Successful sports professionals can earn a great deal more money than people in other important professions. Some people think this is fully justified, while others think it is unfair.Discuss both these views and give your own opinion.
开头段：It is true that sports stars often earn huge salaries. While there are some good reasons why this is the case, I personally believe that it is wrong for these people to be paid more than other professionals.
解析：第一句用It is句型改写题目，用often earn huge salaries对应原文earn a great deal more money。第二句用While句型，表达对一方的认同和自己的倾向，用other professionals 对应原文people in other imortant proffesions.
例2：Some people believe that studying at university or college is the best route to a successful career, while others believe that it is better to get a job straight after school.Discuss both views and give your opinion.
开头段：When they finish school, teenagers face the dilemma of whether to get a job or continue their education. While there are some benefits to getting a job straight after school, I would argue that it is better to go to college or university.
解析：第一句改写题目，呈现一个事实背景，用finish school对应after school，用whether to把两方观点串起来，用continue their education对应studying at university or college 。第二句给出自己观点。
三、agree/disagree类
这类题目的观点可以分为三类：一是完全同意，二是完全不同意，三是同意一部分。以同一题目为例，不同观点相应开头段写法如下：
例题：It is inevitable that traditional cultures will be lost as technology develops. Technology and traditional cultures are incompatible. To what extent do you agree or disagree with this view?
开头段1-agree：It is true that technology is developing at an incredible rate, and that traditional societies and cultural practices are disappearing as a result. I therefore agree with the view that technology and traditional cultures cannot coexist.
解析：第一句用it is 句型改写背景，用traditional societies and cultural practices替换原文traditional cultures，用 are disappearing对应will be lost，用as a result对应原文的因果关系。第二句给出自己立场，同意题中观点，用cannot coexist对应原文are incompatible.
开头段2-disagree：Some people would argue that technological developments lead to the disappearance of traditional societies and cultural practices. I completely disagree with this view because I see no reason why technology cannot coexist with traditional cultures and even enhance them.
解析：第一句用Some people would argue替换原文It is evitable that，用lead to对应原文因果关系。第二句给出自己立场，完全不同意题中观点，并简单说明原因。
开头段3-partly agree：Some people believe that technological developments lead to the disappearance of traditional cultures.While this may be true in the case of some societies or customs, others seem to be unaffected by technology and the modern world.
解析：第一句用Some people believe that替换原文It is evitable that。第二句用While句型，部分认可题中观点，并提出不都是这样。
四、积极/消极类
例题：Some universities now offer their courses on the Internet so that people can study online. Is this a positive or negative development?
开头段：It is true that online courses are becoming a common feature of university education. Although there are some drawbacks of Internet-based learning, I would argue that there are far more benefits.
解析：第一句用It is true that改写题目，用university education替换some universities, 用online courses替换courses on the Internet，用are becoming替换now。第二句用Although回应题目并给出自己观点，用drawbacks替换negative， 用benefits替换positive。
优缺点类可采取类似的写法。
