英语科技论文常用句型结构
1. Introduction(引言):引言中作者通常提出问题并说明论文的研究目的。
1）研究目的
（1）论文导向使用paper, thesis或dissertation这样的特征名词，直接提及研究论文本身，而且此类句子通常采用一般现在时态。常用的句型有：
The purpose of this paper is…/The aim of this report is…/The objective of the paper is to obtain quantitative about the particles size distribution/to model the dynamic behavior in the super-or near-critical CO2 extraction.
（2）研究导向study, research, investigation或experiment等特征名词被用来强调研究活动本身。这类句子是表达已经过去的事情，所以使用一般过去时态。
The purpose of the experiment reported here was…/The aim of this study was…/The objective of this research was to determine the preferred viewing distance for work at a visual display unit./to examine the apparent osmotic behavior of some contemporary commercial reverse osmosis membranes.
或用被动结构：In the research described here, /In this study, /In the present investigation, /In this research, /In the experiments
reported here, vertical nutrient mixing in late summer in a test area 20 kilometers off the coast was examined.
描述研究目的时，最简单的句型是用this paper, this study, this project, this research等词做主语，后面用实意动词作谓语，如investigate, discuss, examine, test等，宾语为研究内容。即This paper/This study/This project/The present study/This research/Our project/This survey/This thesis concerns/tests/investigates/reports/discusses/describes/explains/calcul ates/examines/analyses/proposes/demonstrates/evaluates/measures….
2）研究价值
Although much research has been devoted to A, /While much work has been done on A, /Although many studies have been published concerning A, / While many researchers have investigated A, /Although much literature is available on A, little research has been done on B. / little attention has been paid to B. /little information is available on B. / little work has been published on B. /few researchers have studied B. / few studies have investigated B.
在这一步骤中，作者通过指明过去相关研究中尚未处理或解决的问题或所派生出的新问题，常用句型的时态是一般现在时和现在完成时。
2. Body （正文）
1）theory base理论分析的常用句型
在正文部分的假设、理论分析、数理模型的建立以及计算过程中，常常要推导并描述公式，作者应了解和掌握描述公式的基本句型。科技论文理论分析部分中资料大部分表达数字与逻辑关系，句型使用一般现在时态。
Substituting M in/into N, we obtain/have/get ….
Substituting M/Substitution of M in/into N gives/yields/ produces/ results in….
Let us now consider the case: the dynamic link parameters are unknown.
If m=1.2, then we have the following equations:….
Given that m =1.2, we obtain….
The equation for Aˊcan be written(expressed)as….
The relationship between m and n is as follows:….
A is inversely proportional to B, as shown below.
If the same material is used, the above equation reduces to….
We will now reduce Eq. (3) to a simpler form:….
The mass velocity G is defined as.…
We will now integrate Equation (2) in order to derive the solution.
2) diagram图表文字说明中的常用句型
在文字说明中，如果提及图表，表格用“Table+序号”表示，如“Table 1 shows…”。其他各种类型的图都可以用“Figure+序号”表示，如“From Figure 2 we learn…”。“Figure”这个词可以简缩为“Fig.”，
但必须做到前后统一，如用缩写，便都用缩写。动词要用一般现在时态。常用动词有show, provide, give, present, summarize, illustrate, reveal, display, indicate, suggest 等。例如：
·Table 1 shows the majority of the participants have previous knowledge of the elements of a safe well.
·Table 2 provides details of the test results.
·Figure 4.2 gives the results of the experiment.
·Both of these questions receive very high ratings (see Table1).
·The results show that 92% used information on water testing in local news outlets (Figure2).
动词的语态可以灵活使用，这样能使句型多样化，上述句型也可变为被动语态。
· As shown in Table 3, …
· As can be seen from the data in Table 1, …
· As described on page 24, …
3）result介绍研究成果的常用句型
（1）根据本人的研究结果做出推论。
These results suggest that untrained octopuses can learn a task more quickly by observing the behavior of another octopus than by reward-and-punishment methods.
（2）作者解释研究结果或说明产生研究结果的原因。
These findings are understandable because the initial
annealing temperature dictates the state of conformational structures.
（3）作者对此次研究结果与其他研究者曾发生的结果作比较。These results agree with Gerner’s analysis, in that Q max varies inversely with length and to the third power of the pipe width.
The recognition rate of our system is significantly higher than that reported for Token’s system.
（4）作者指出自己的理论模型是否与实验数据符合。
The measured temperatures along the heat pipe are all highly consistent with the predictions of the theoretical model.
The experimental measurements are very close to the predicted values.
·There is a high level of agreement between the theoretical predictions and the experimental data.
从以上句型中可以看出学术论文在陈述研究成果时，通常使用一般现在时态。
当评论的内容为对研究结果可能的证明时，句子的主要动词之前通常加上may或can等一般现在时态的情态动词。例如：· The layer structural or some other mixed complex material may be the most suitable refrigerants for the Ericsson magnetic refrigerator.
·The results can be explained by a giant magnetic entropy
change.
·A possible explanation for this is that the hank visual programming language can avoid some of the syntactic problems associated with textual programming languages.
4）discussion讨论部分的常用句型
(1)概述结果
The results indicate/ prove/ show/ reveal that….
·These results provide substantial evidence for the original assumptions.
·These experimental results support the original hypothesis that …
· Our findings are in substantial agreement with those of Davis.
·The present results are consistent with those reported in our earlier work.
·The experimental values are all lower (higher) than the theoretical predictions.
· These results contradict the original hypothesis.
· These results appear to refute the original assumptions.
·Overall, our study revealed a variety of patterns at the community and population levels, none of which seem to indicate obvious decline in southeastern Ohio’s oak-hickory forests.
·The results given in Figure 4 validate (support) the second
hypothesis.
(2)表示研究的局限性
· It should be noted that this study has examined only …
· This analysis has concentrated on …
· The findings of this study are restricted to …
· This study has addressed only the question of …
· The limitations of this study are clear …
· We should like to point out that we have not …
· However, the findings do not imply …
· The result of the study cannot be taken as evidence for …
·Unfortunately, we are unable to determine from this data that…
5）conclusion结论部分的常用句型
· Two factors to influence mold filling have been studied ….
·Through the example of a 60-storey building, it has demonstrated that a simplified approach can be used ….
·Overall, our study has revealed a variety of patterns at the community and population levels.
用主动语态时，常常用this paper, this investigation, this study, this survey, the results, the analysis或we做主语。
This study/This investigation/The result clearly demonstrates that/discovers that/reveals that/has described/has described/has
shown/has proposed/discusses/represents)…
作者有时对自己研究结果采取慎重的态度，不那么肯定地说“结果说明了……“、”证明了……“等，用情态动词是常用的技巧。最常用的情态动词有will, can, may，及其过去式would, could, might等，表示“可能”之意。例如：
·Evaluation of decline symptoms in smaller size classes might provide additional useful information to be used in understanding the oak regeneration problem.
·Changes occurring due to insects and pathogens may be a natural and necessary phenomenon.
·Participation in a science fair beyond the local level and supportive help from parents and other adults may also improve the effectiveness of student science projects.

What is worse is that some of them may even lose interest in study and so drop out of at an early age.

初中英语语法大全：英语五个基本句型1简单句、并列句、复合句 根据语法形式，即句子的结构，英语的句子可分为简单句、并列句和复合句。 1简单句 句型：主语+谓语 只包含一个主谓结构，而句子的各个结构都只由单词或短语表示。简单句有五种基本句型，详见第十七章。 They are playing baseball in the garden. 他们正在公园里打棒球。 Her brother and sister both are teachers. 她的哥哥和姐姐都是老师。 2并列句 句型：简单句+并列连词+简单句 （常见的并列连词有and，but，or） 并列句是由两个或两个以上的简单句连接而成。并列句中的各简单句意义同等重要，相互之间没有从属关系，是平行并列的关系。它们之间用连词连结。 My friend was at home，and we talked for along time. 我的朋友在家，我们谈了好长时间。 Her father is a doctor and her mother is a teacher.
她父亲是个医生，她母亲是个老师。I liked the story very much but Li Ming wasn't interested in it.我非常喜欢这个故事，可是李明却对它不感兴趣。 Hurry up，or you'll be late. 快点，否则你就会迟到的。 3复合句 句型：主句+连词+从句；或连词+从句+主句（包含一个主句、一个或一个以上的从句，或只包含一个从句，但有两个或两个以上的主句的句子叫复合句。） 句子的成分 组成句子的各个部分叫做句子的成分。句子成分包括：主语、谓语、表语、宾语（直接宾语、间接宾语）、宾语补足语、定语和状语。主语和谓语是句子主体部分（在英文中一般的句子必须有主语和谓语）。表语、宾语和宾语补足语是谓语里的组成部分。其他成分如定语和状语是句子的次要部分。下面我们分别讲述一下句子的各个成分： 1主语 主语是谓语讲述的对象，表示所说的“是什么”或“是谁”。一般由名词、代词、不定式或相当于名词的词或短语来充当。它在句首。 We study in No.1 Middle School.（讲述“谁”～） 我们在一中学习。 The classroom is very clean. （讲述“什么”很干净） 这间教室很干净。 Three were absent.（数词作主语）
