科研論文的撰寫是將研究成果進行系統(tǒng)全面總結，并向同行進行展示的重要環(huán)節(jié)。但是在論文寫作，尤其是英文的論文寫作過程中，初學者總會面臨無處下手的局面，這其中既有專業(yè)知識的積累不足或者英文水平不過硬的關系，也有不了解英文論文寫作中常用句型及表達的原因，在本文中，我們就為大家總結了一些經(jīng)典的表達方式和句型，相信通過這篇文章，讀者能了解和掌握英文論文基本的描述方式，為以后論文的寫作起到一定的幫助。

引言

1

引言部分主要是對前人工作的全面總結，進而指出目前研究中存在的問題，最后引出本文的研究內(nèi)容以及解決方法。這方面的內(nèi)容體現(xiàn)了作者在閱讀文獻時的深度、廣度以及發(fā)現(xiàn)問題的能力，能使讀者能了解文章的梗概和研究思路。

研究現(xiàn)狀的敘述

a. Many / Several / A number of / Few researchers have studied / investigated / examined / explored / reported on / discussed / considered + research contents

b. research contents has been studied / investigated / examined / explored / reported on / discussed / considered by many / several / a number of / few researchers

c. The study of research contents has been widely reported / found / published in the literature

d. Many studies / researchers / investigations / experiments on research contents have been performed / done / published

e. Somebody showed / found /reported / noted / suggested / observed / point out that……

f. Somebody investigated / has investigated……

指出存在問題

a. However, research contents have not been considered / taken into account / have been ignored

b. However, few studies have been done on / few studies have been published on / few studies have reported on……

研究內(nèi)容

a. This paper describes / presents / develops / proposes a new model / theory / method for research contents

b. The objective / purpose / aim of this paper / study is to develop a new model / theory / method for research contents

c. In this paper, a general numerical analysis theory is presented, which is capable of solving……

d. research contents is presented in this paper

實驗部分

2

這一部分主要對實驗的過程進行詳細描述和說明，鑒于不同學科在實驗部分的描述不盡相同，下面列舉一些實例以供參考：

a. All chemicals were used as received and without any further purification.

b. ……was added into an organic solution……

c. Subsequently, the organic mixture was heated to……

d. Then the two-phase mixture was transferred into……

正文

3

正文部分主要包含對實驗結果的描述以及解釋，是論文的核心部分，通過對正文中豐富實驗數(shù)據(jù)的分析可以解決作者在引言中提出的問題，從而得到實驗研究所得出的結論。

在對圖表的描述中，一般采用Figure 1 / Table 1 shows / provides / gives + 圖表內(nèi)容描述的形式，或者采用圖表內(nèi)容描述 + (Figure 1 / Table 1)來進行說明。此外，也可以使用被動語態(tài)進行描述，例如As shown in Figure 1，As described on page 1，As can be seen from the data in Figure 1。

對實驗結果的分析常使用The results indicate / prove / show / suggest / reveal / that + 實驗結果的分析進行說明。例如，These results provide substantial evidence for the original assumptions。

對于科學研究來說，總有其局限性和考慮不足的地方，因此在文章中指出本次研究存在的局限性也是十分必要的，例如，可以使用However, the direct proof was not obtained, and the detailed reaction process was not very clear and needed further investigation來向讀者說明本次研究還未解決的問題，除此之外，下面這些句型也是十分常用的：

a. It should be noted that this study has examined only……

b. This analysis has concentrated on……

c. The findings of this study are restricted to……

d. The limitations of this study are clear……
