抓住下面的四个关键点，写作也许不是那么困难的事情。
第一，使用不同的词汇
a.使用同义词
比如以下的一些写作高频词汇的同义词，你一定要掌握，出现的尤为频繁。
important→essential, crucial, vital, significant,
think→claim, believe, consider, deem, figure out
nowadays→currently, at present, now, recently, in recent years, these days
b.改变词性
这是一种稍微难一些的方法，要求你的语法基础非常好，你才能灵活自如的运用。
n. → v.
Eg：When we look at a comparison between A and B…
When we compare A and B…
Adj. → n.
There are a variety of solutions to the problem.
There are various solutions to the problem.
c. 使用不同的承接词。
承接词在文章当中的使用相当频繁，不仅是段落和段落的连接，还包括句子和句子的连接。背住一些常用的承接词比你的改写将会有极大的作用。
because of → due to, owing to, because, as, since, for
but → however, nevertheless, nonetheless, whereas
so → therefore, hence, thus, consequently
d.形容词的逆向表达。
在某些形容词上进行修改，会达到非比寻常的效果。
Eg: not as easy as…→more difficult than…
Not uncommon→common
The cheapest → the least expensive
第二，使用不同的句型
a. 改变词序。
这是非常简单的一种方法，完全不用动脑筋就可以进行改写。常常将句子中的状语(包括状语从句)换位置。
Eg: For many years, people have believed ….
→People believed… for many years.
After this programs has been solved, work on … can continue.
b. 主动语态和被动语态的互相替换
Eg: Trained scientists performed this research.
→This research was performed by trained scientists.<...
