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Threanten代替is a threat to，不仅表达更加生动，整体行文也更简洁有力。
2.用词简洁
英文写作中用词简洁有很多方式，下面我们举几个例子，为大家拓展一下思路。
（一）He crashed down on a chair which produced a protesting sound.
He crashed down on a protesting chair.
这个句子中将定语从句简化为一个分词短语，来修饰名词成分。
（二）My daughter had to change schools when my work schedule was busy and this made it necessary for me to move houses.
My daughter had to change schools when my busy schedule made it necessary for me to move houses.
用形容词短语代替从句。有时候，单独的形容词就可以表示复杂的意思。
The road was frozen and slippery and one could hardly see clearly,so the road accident was caused.
Icy road and poor visibility led to the accident.
（三）He spends nearly 3 hours on watching sports events.The fact that he was completely absorbed in sport interfered with his studies.
He spends nearly 3 hours on watching sports events.His complete absorption interfered with his studies.
在这里，使用抽象名词，大大简化了句子。让我们再看一个例子：
He is capable,easygoing and works efficiently.He will surely be promoted.
His aptitude,personality and efficiency guarantee his promotion.
3.善用替换词，做到用词多样性
丰富的词汇变换手段包括使用同义词、近义词和指代词。
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.
