在sci论文的写作中,对于时态、语态的运用上十分重要。如果使用不当,很可能会曲解文章所要发表的意思,从而影响文章的整体阅读和理解。因此这里关于怎么用sci论文时态语态(附实例)这一问题,给大家详细介绍一下。
这里总结了SCI论文的时态、主动语态和被动语态,并结合具体的例句进行说明,如下:
1、时态:sci论文中最常用的时态有两种,分别是现在时和过去时。
当阐述一个现象或概念时,使用现在时态,例句:Turtles are bigger than beetles.
当描述你或别人所做的事情时,使用过去时态,例句:Darwin observed the difference in adaptability between turtles and beetles.
注意,我们也可以在一个句子中混合使用不同的时态,例句:Darwin observed that beetles are more adaptable than turtles.
2、被动语态和主动语态
1)被动语态的使用
阐述一个普遍真理,例句:Rules are made to be broken. [任何人,无论何时]
想要强调被行动的人或事,例句:Insulin was first discovered in 1921 by researchers at the University of Toronto. It is still the only treatment available for diabetes.
被动语态强调的是你的实验,而不是你自己。
2)可以使用被动,也可以使用主动
如More than 50 LRRK2 mutations are known now. All of the mutations (mostly, missense mutations) were found in heterozygote, segregated with the disease and were not detected in a control sample. In addition, LRRK2 mutations were not detected in other neurological disorders. Autosomal dominant PD was demonstrated to result not only from the most common G2019S mutation, but also from at least five other mutations.
该部分产生的问题是,读者无法从句子本身知道谁对每个发现负责。是同一个人还是不同的人?他们的专业是什么?他们使用了什么技术手段来实现他们的成果?所有这些都还很模糊。
3、使用主动语态的基本技巧
在你的文献综述中,你可以对不同来源的结果进行归类,同时使句子传达有用信息:
. . . while a large body of literature has explored large-scale geographical patterns, and several recent papers have studied disease dynamics in a metapopulation framework, few empirical studies have focused on the patterns and mechanisms behind disease clusters at small spatial scales (“disease foci”), especially in wild host–pathogen systems. (Introduction, Ecology)
