1.
使用同义词。
降低重复率的一个显而易见的方法是将其中的单词替换为具有相同或相似含义的不同单词。
但是，必须注意不要在同一个句子中替换太多单词或使用太不常用的单词，否则会降低文本的可读性。
同时还应该确保这些替换不会改变文本的含义。适度使用这种技巧，每句中最多替换一两个单词。
改写前：The survey was administered between June and July of 2021.
改写后：The questionnaire was distributed between June and July of 2021.
2.
使用多种过渡词。
这是第一个技巧的变体，但重要到足以单独来说一说。过渡词用于将句子连接在一起，帮助读者理清文稿的逻辑，包括moreover, furthermore, however, after, additionally, next, finally等等这些词。虽然并非所有的过渡词都可以互换，但在方法部分交替地使用它们不仅可以降低重复率，还可以使文稿更易于阅读。
改写前：First, we collected the samples. After that, we weighed them. We also measured their diameters. Finally, we disposed of them in accordance with the laboratory’s safety guidelines.
改写后：To begin, we collected the samples. Then, we weighed them and measured their diameters before we disposed of them in accordance with the laboratory’s safety guidelines.
3.
切换语态。
英语中有两种语法语态：主动语态和被动语态。在主动语态中，句子的主语正在做某事，而在被动语态中，有某事正被施加在句子的主语上。
为了减少重复，可以将句子从主动语态改写成被动语态，反之亦然。
改写前：Then,qPCR was performed on the samples.
改写后：Then, we performed qPCR on the samples.
