“主体”顾名思义，就是文章的最重要部分，它最基本要求是“丰实”，一篇文章的主体的好坏决定你的文章的好坏，因此，写好一篇文章，主体的“丰实”必不可少的。下面就让美国论文辅导老师来简单说下怎么样才能写好一篇文章的主体。
一、举实例
思维短路，举实例!提出一个观点，举实例!提出一个方案，举实例!而且者也是我们揭示一个观点最好的方式，任何情况下，只要我们无法继续文章，不管三七二十一，尽管举例子!
In order to attract more customers, advertisers have adopted every possible stimulative factor in making ads, such as sound, light, colours, cartoon films and human performance. For instance, to advertise a certain food, advertisers will ask an actor or actress to sit at a table and devour the seemingly delicious food while they fime him or her.
更多句型：
To take … as an example, One example is…, Another example is…, for example
二、做比较
方法：写完一个要点，比较与之相似的;又写完一个要点，再比较与之相反的;
世界上没有同样的指纹，没有相同的树叶，文章亦同，只有通过比较，你才会发现二者的相同点(through comparison)和不同点(through contrast)。下面是一些短语：
相似的比较：
in comparison, likewise, similarly, in the same manner
相反的比较：
on the other hand, conversely, whereas, while, instead, nevertheless, in contrast, on the contrary, compared with …, …
三、换言之
相比其他的两个方法，我个人觉得这个方法还是不要经常使用的为好。“换言之”俗称来说就是换句话来说。使用这个方法的原因主要是因为没话说了，需要换句话来说，为你的文章增添一些字数，换言之就是让读者充分理解你的观点，可是实际上就是重复重复再重复。下面就有两个例子：
I love you!
I am enthusiastic about you. That is to say, I love you.
I am wild about you. In other words, I have fallen in love with you.
或者上面我们举过的例子：
I cannot bear it.
可以用短语表达：I cannot put up with it.
因此可以这样说：I cannot bear it. That is to say, I cannot put up with it or I am fed up with it.
