写essay令人最头疼的问题之一就是: turnutin重 复率过高，正常来说，如果essay正文的turnitin重复率低于10%，就很安全了，如果高于10%，建议还是paraphrase- -下比较保险。
怎么paraphrase?亲测如下放法很有效，不妨一试:
1.词性转换，例如:动词换成名词或动名词，
improve make improvement
2.表达方式同义转换，例如: The study by xxx findsthat……as a significant finding by xxx，…
3.主动换被动or被动换主动，例如: xxx finishs thetask…the task is accomplished by…
4.长句拆分成短句，例如: xxx leads t… as aconsequence，
5.短句合并成长句，例如: to overcome the difficulty,he needs to…it is necessary for him to xxx so as toget over the difficulty.
Paraphrasing主要就是这些方法，有新的再补充。
