托福作文也需要不断的练习与积累，为了帮助考生们更加有效的备考托福，出国留学网托福考试栏目为大家提供“2016托福写作技巧：扩充主干句”，希望考生们能有所收获。
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
没话说了，可以换一句话再说，让你的文章在多一些字，或者文邹邹地说，是让读者更充分的理解你的观点。
实际就是重复重复再重复!下面的句子实际上就三个字 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
更多短语：
in more difficult language, in simpler words, put it more simply
