今天，小编来分享一下论文润色，SCI论文的主题句（Topic Sentences）怎么写：
主题句通常是段落开头的一句话，是整个段落的小主题或者中心思想，写SCI论文的时候，用好主题句可以让我们的写作有章可循，大大提高读者的阅读效率。
主题句构成 = 你的主题 + 一个要点（Topic sentence = topic +central point）
所以，一个好的主题句应该保持简短、精确且详尽。
主题句通常出现在段落的开头。
在下面的《Anatomy of Criticism》的例子中:
The tragic hero is typically on top of the wheel of fortune, half-way between human society on the ground and the something greater in the sky（主题句）. Prometheus, Adam, and Christ hang between heaven and earth, between a world of paradisal freedom and a world of bondage. Tragic heroes are so much the highest points in their human landscape that they seem the inevitable conductors of the power about them, great trees more likely to be struck by lightning than a clump of grass. Conductors may of course be instruments as well as victims of the divine lightning: Milton’s Samson destroys the Philistine temple with himself, and Hamlet nearly exterminates the Danish court in his own fall.
这个段落的结构简单而有力：第一句主题句提出一个抽象的观点，段落的其余部分使用具体的例子作为证据来阐述这个观点。
不一定，主题句放在哪里，这可能需要根据具体需要和个人习惯。
例如:
We found in comedy that the term bomolochos or buffoon need not be restricted to farce, but could be extended to cover comic characters who are primarily entertainers, with the function of increasing or focusing the comic mood. The corresponding contrasting type is the suppliant, the character, often female, who presents a picture of unmitigated helplessness and destitution（主题句）. Such a figure is pathetic, and pathos, though it seems a gentler and more relaxed mood than tragedy, is even more terrifying. Its basis is the exclusion of an individual from the group; hence it attacks the deepest fear in ourselves that we possess—a fear much deeper than the relatively cosy and sociable bogey of hell. In the suppliant pity and terror are brought to the highest possible pitch of intensity, and the awful consequences of rejecting the suppliant for all concerned is a central theme of Greek tragedy.
这个段落的第一句话用于过渡的：它为主题句做准备。
第二句才是这个段落的主题句。过渡句通常是在上一个段落和当前段落之间的桥梁。
写主题句没有固定的模式
相反，你应该努力改变主题句的形式
相同的套路怎么能让你的文章惊艳审稿人呢
不一定，但是大多数的段落都是包含主题句的
小编建议：
主题句相当于论文的大纲。写作每个段落时，可以先写主题句，然后根据主题句，去丰富论文内容！
论文写作是个不断研究、修改、思考、实践的过程，而主题句更是这种循环的结晶。
主题句和SCI论文紧密的联系在一起，可以帮助加强论文的连贯性。
主题句应该是推进论文向前发展的。
如果SCI论文的introduction中包含了一个主题句，那么主题句中最好加入keyword关键词。
如果一个主题句重述一个主题，那么它是多余的，你最好重写这个主题句。
如果多个主题句重述一个主题，即使这些主题句使用不同的词语，那么它也是重复的。
以上就是小编今天关于主题句的分享啦，建议收藏，对大家的SCI论文写作很有帮助！现在是时候把你刚刚学到的东西实践起来了!
