一、举实例
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.

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，让你的托福写作文章在多一些字，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.
