毕业论文论文用语

毕业论文论文用语

一、时态

时态是个比较复杂的问题虽然有一般的规则但往往在实际文章中很难把握总体的

规则已在前边讲过需要重申的是在同一段落中要避免时态跳跃详见学术论文的写作最常见的描述一般现象的时态是一般现在时有时也用一般过去时或一般将来时

需要注意的语法

In recent years作时间状语时通常要用完成时

In recent years,Plesch and coworkers have concluded that many so-called cationic polymerizations do not proceed through intermediates of an ionic nature.

二、数词

数也有其复杂化特别是在学术论文里有是很难顾及数上的逻辑但一般不将逻辑上

的问题视为语法错误只须注意在一个句子中的数和谓语动词的统一即可

以下是需要注意的语法

不规则变化的单复数

单数复数

criterion criteria依据

phenomenon phenomena现象

medium media介质

radius radii半径

index indices指数

appendix appendices附录

stimulus stimuli刺激

basis bases基础

2

synthesis syntheses合成

matrix matrices基体

Novel biomaterials with improved,specific biological action are being developed using polymers that are responsive to environmental stimuli.

一些数有特殊性的名词

data,kinetics通常作复数名词

research,work：不可数名词

The data in Table1are obtained from the reactions at different temperatures.

The kinetics of polymerization within each droplet are the same as those for the corresponding bulk polymerization.

Much research has been done to redirect the tropism of retroviruses by engineering the envelope glycoprotein.

Most research on poly(ortho esters)has focused on the synthesis of polymers.

一些结构的数<；主谓的统一>

*The number of复数名词：整个做主语时谓语应为单数；但此句的动词have是从句的谓语而从句是形容mechanisms.
