在Essay写作中，应该尽可能选择短小有力的action verb，才能写出生动有力的文章。比如说，如果想要表达“让某事变得更快”，你第一想法可能是“make it faster”，但是如果我们用动词accelerate来替代的话，会使整个表达更加生动。下面我们再来看两个例子：
His criminal record made him unable to be admitted to the university.
His criminal record disqualified him from being admitted to the university.
我们可以用disqualify来代替make sb unable to。
Ecological imbalances is the biggest threat to the survival of wild animals and plants.
Ecological imbalances threaten the survival of wild animals and plants,even human beings.
用Threaten代替is a threat to，不仅表达更加生动，整体行文也更简洁有力。

同义词/近义词的使用比如：I first heard this tale shortly after the Cultural Revolution(1966-1976).Later someone told me that the story appeared in a travel magazine.
指代词的使用就更常见了。比如：Perhaps is will suffice to mention the nuclear bomb.Imagine the effect on a reasonably advanced technological society,one that still does not possess the bomb,of making it aware of the possibility,of supplying sufficient details to enable the thing to be constructed.
比如：She had straight A’s and scholarship offers from some of the most prestigious universities in the country.
