雅思大作文的主体段一般由两个段落组成。写作时要以开头段的主旨句为基准，并把主旨划分为两个方面分别进行充分展开和论述，从而使读者能够信服作者的立场、观点和态度。
主体段的评判标准通常是中心是否突出、论证是否严密、充分、清晰、连贯和符合逻辑。一个有说服力的主体段需要回应以下几个问题：
一、段落中心是什么？(Main idea?)
二、为什么和怎样？（Why?/How?)
三、有什么样的例证？（Evidence?/Example?)
四、结果/后果怎样？(So what?/If not?/Bigger impact?)
用传统中文的行文方法我们可以把雅思大作文主体段落的撰写概括为以下6个步骤：起、承/因、例、果、转、合。所以建议大家可以用6句话来阐述每个主体段的内容。
以下结合我个人的2020首考雅思大作文主体段的创作来做一个具体的说明。
首先我们来一起回顾一下2020年1月4日中国大陆雅思首考的大作文的问题和我在上一篇文稿中撰写的开头：
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)
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。）
下面就是我依据上面的开头写的两个主体段落和括号里面的段落写作的简要说明：
Admittedly TV trial can serve the purpose of educating the public about legal knowledge and bringing down the crime rate.（起） Through watching live broadcasting of legal cases in front of TV at home people can gain a handy and vivid access of law issues, better informed about the justice system and rule of law. （因1）As a result, they can know how to better protect themselves and their family members in case their own civil right is under threat through legal weapons.（果）In addition, allowing camera into the courtroom and meting out justice to the offenders in real time can help curb crime in the community to some extent by making potential criminals more ashamed of themselves and aware of the possible consequences of breaking the laws, and therefore withdrawing from committing criminal acts, such as burglar, drug-dealing or drunk driving so on and so forth.（因2+果2+例）
点评：我在这个主体一段里我主要以让步的方式论述了电视审判的好处。
On the other hand, filming court trials exerts considerable negative effects on nearly all the stockholders like the lawyers, judges, prosecutors, plaintiffs or defendants in the judicial proceedings and thus undermine the judicial system. （起）To begin with, the presence of a TV camera inside the courtroom may make all parties of the trial become self-conscious and fail to perform their due obligations, particularly the judges who may play for the video camera and concern more with their own external personal image and being a legal celebrity in uniform instead of bringing the guilty ones to justice and clear the name of the innocent people. （因1）Besides, the media who is involved in the live show might sway the public opinion of little expertise in one way or another and so hinder the jury and judges from making the right decision about the innocence of the suspect.（因2） In addition, it may degrade the sanctity and dignity of court trial down be a form of entertainment like a reality TV show or circus show. Accordingly, people may harbor some contempt for the judicial institutions and ignore law and order. （因3）What's more, it may violate the right to privacy of the defendants and may even put the life of witnesses or police informants in danger so they become reluctant in giving witness in court and lead to the interference with the judge and jury's deliver of a impartial verdict in the end.（因4）Last but not least, it may even promote crime occurrence through glorifying the criminal and cause uneasiness of the audience by exposing too many horrible and gruesome details about the criminal acts like murdering, kidnapping or defrauding.（因5）
点评：这里我主要论述的是直播庭审过程的弊端。
接下来继续为大家讲解一下结尾段的写作，敬请各位关注。
