3、尽量避免重复使用单词或者词组。特别是近距离集中在某一两句话里使用。

例如：The author argues that to understand one’s own culture, one must know about at least one another culture which is distinctly different from one’s own culture. While as I am concerned, I can’t agree with the author’s assertion.

　　这一个开头，总共两行字，却连续出现了4个One，3个culture。如果你把这段话大声朗读一下，就会觉得别扭、好笑了。连续使用相同的单词或者词组（包括短句），体现的是作者词汇量匮乏，写作风格较差，遣词造句能力不强。给读者的感觉就是昏昏欲睡。

　　很容易的我们就可以改正：The author argues that the knowledge of another distinctly different culture helps us to truly understand our own. However, I disagree with this assertion.

　　这句话把原来的三句分句合成了并无冗长感觉的一句。精简的同时，也恰当地避免了重复多次使用culture，one的问题。用了"this assertion"，也避免了在近距离使用两个"author"。

4、避免使用从句套从句的超长句子。

　　学术性的文章，应当避免追求华丽词藻和句型。作为非母语者，我们在语感上面已经处于劣势。为了避免缺乏语感而造成的很多语法上面、句子结构上面的小失误，我们更应该尽量避免使用长句。看了很多作者的文章，长句造成的后果通常有：单复数混淆，it、that指代不清，从句两头时态不符，连接介词错误，等等。

例如：Things happened in the past, known as history, is great treasure for us huan beings, through and only through studying the past can we gain valuable experience which serves as a means of guiding our development of the society.

　　例子中作者用了3处逗号，而事实上面，从句间关系并非密不可分。我们可以很轻松的分成三句话，作者写得安心，读者读得舒心，做到真正的言必达意。

History consists of the things happened in the past and it is a great treasure to human beings. Through and only through studying the past thoroughly can we gain valuable experience from history. The historical experience serves as a means of guidance for the new development in the society.

5、避免陈词滥调等废话

例如：For getting a satisfying score, students have to prepare for and review their texts frequently, remember all the knowledge they have learned deep in mind, enlarge their learning if it is possible and so on, especially when examinations are coming. All these efforts, no matter what their aims are, will surely lead to a corresponding paying back.

　　段中的这一句"no matter what their aims are"，在整个上下文表达上面没有任何实质性的意　义，完完全全是句废话。
