英文学术论文写作技巧(写作常用句型)
英文学术论文写作技巧（常用句型）用英语写学术论文的目的主要有两个，一是参加国际学术会议，在会议上宣讲，促进学术交流；二是在国际学术刊物上发表，使国外同行了解自己的研究成果，同样也是出于学术交流的目的。
不同的学科或领域、不同的刊物对论文的格式有不同的要求，但各个领域的研究论文在文体和语言特点上都有许多共性。
了解了这些语言共性，便会起到触类旁通的作用。
对我国青年学者或学生来说，用英语写作的难点不是没有写作材料，不是不熟悉专业词汇，也不是没有打下良好的英语基础。
用英语写论文难，是因为不太了解学术英语的语言特点。
关于学术英语写作的语言技巧，我们已在第一部分作了较详细的介绍。
此部分讨论学术论文写作的方法，包括学术论文写作中常用的句型结构，我们都在此作较详细介绍，以便读者模仿练习，将写作工作化难为易。
一般来说，一篇完整规范的学术论文由以下各部分构成：Title(标题)Abstract(摘要)Keywords(关键词)Table of contents(目录)Nomenclature(术语表)Introduction(引言)Method(方法)Results(结果)Discussion(讨论)Conclusion(结论)Acknowledgement(致谢)Reference(参考文献)Appendix(附录)其中Title，Abstract，Introduction，Method，Result，Discussion，Conclusion，Reference等八项内容是必不可少的(其他内容根据具体需要而定)。
在这八项内容中，读者最多的是Title，Abstract和Introduction部分，读者会根据这些内容来决定是否阅读全文。
也就是说，一篇研究论文赢得读者的多少，在很大程度上取决于Title，Abstract和Introduction写得好坏。
因此这三项内容将各分章详细加以讲述。
学术论文的正文一般包括Method，Result，Discussion三个部分。

A xx is a latecomer in the part representation arena.10. At the time of this writing, there is still no standard way of xx11.
