雅思大作文的开头的目的主要有两个：一是引入话题；二是回答、简要论述问题并为主体段落的展开做铺垫。
以下我结合2020年1月4日中国大陆雅思首考的大作文的话题开头的写作为例做一个说明。这个写作题目如下：
In some countries, the criminal trials are shown on the TV and the general public can watch them. Do the advantages outweigh the disadvantages? (2020/1/4)
从题目中我们可以看出这是一道有关犯罪和媒体混合题材的利弊双边讨论的问题，同时也是一道分别在2016年和2018年考过的旧题。下面是我从国内即时社交媒体三个有关雅思写作的微信公众号找到的三个比较好的开头给大家做一个解析。
第一个是广外的Icy老师在她2020年1月7日她的微信公众号《Icy的框架写作小乐园》的开头。她在开头中这样写到：Some nations allow trials of criminal cases to be televised in order for the public to watch how they are processed. In my opinion, both viewers and these countries could benefit enormously from this practice.
在这里Icy老师首先娴熟地使用了同义词替换和句子结构转换的方法用自己的话对作文的前一部分话题做了一个转述。接下来她又开门见山明确地提出了自己对这个问题的支持性的立场，为下文的展开指明了方向。
第二个开头是一位自称有7年雅思写作教学经验的叫坡姐 Lydia的微信用户开设的微信公众号《雅思写作怎么破》在2020年1月7日发表的同话题开头：
There is no doubt that these days the criminal trials have been accessible to (易接近的，能达到的)the public via mass media, like television. While this may bring about some problems, I still believe that this progressive policy will definitely benefit more not only individuals but also the society.
这个开头里面我觉得第二个句子中的副词"more"放在句子最后读起来更通顺一些。这段开头其他地方没有什么问题。对比Icy老师的范文的开头，这个开头的思路跟Icy老师基本一致，不同之处在于这个开头在第二句主旨句里面做了一个让步，先抑后扬，使得这个句子结构更加精细，语感上也更有张力。
第三个开头是国内雅思写作大咖广外资深的英美文学教授唐伟胜老师在他今年1月5日他发表在自己的微信公众号《唐老雅英语写作工作室》的同话题的开头：Whether criminal trials should be shown on TV or not has always been a controversial（有争议的）issue. After discussing the advantages of this practice and its disadvantages, I come to believe televising criminal trials is a good thing as long as its negative effects are brought well under control.
唐老师在这个经典的开头先是使用一个whether or not引导的主语从句导入话题，之后用了一个用表示时间先后次序的连接代词after引导的复杂的动名词形式做状语和一个以I come to believe为主谓语的复合宾语从句提出了自己对话题的有条件的赞同，即只要严格控制负面影响，电视审判是一件好事。
好，以上就是我对三个同话题的优秀雅思大作文开头的分析供大家参考。
接下来跟大家分享一下我的英文开头并附上括号里面的中文说明：
The portrayals of court proceedings on TV has become a familiar scene in a number of countries nowadays.（注：这句话我对话题做了一个笼统的转述。）Some people believe that televised criminal trial has more benefits than drawbacks due to its educational and deterrent value, however in my view, the cons of airing the criminal trials on TV to the general public outweighs the pros by distorting the truth-seeking process of a criminal trial and impairing the authority of the justice system.（注：这是我的主旨句。在这句话里我回应了问题并提出了自己的观点和核心理由。）
最后如果大家有兴趣可以跟我一起来动笔练习一下另外三个不同话题的开头。开头完成之后可以与我给大家附上的参考答案做一个对比，看看自己的作文开头有哪些方面做得比较到位，哪些方面还可以进一步改进和完善。
1、The best way to improve health is to do regular exercise. To what extent do you agree.
2、Many governments think that economic progress is their most important goal. some people, however, think that other types of progress are equally important for a country. Discuss both views and give your own opinion.

参考答案
（1）The most effective solution to enhance health is regarded as frequent physical exercise. In my opinion, I agree that exercise is the key to good health, however I also believe that balanced diet and healthy lifestyle are also critical.
（2）How their country's progress should be measured is a heated topic among the government and citizens of country. While I advocate that economic growth is essential. I believe that other forms of progress are just as essential.
