Introduction开头的几句话要使用题目中的关键词, 以便使文章直接进入主题, 把读者引入到你的研究课题中去. 不要写与主题无关的 字句.比如文章的题目是"A New Strategy to Improve the Production Yield of Insulin”", 开头的第一句话中就应 有 Insulin. 接下来就简要介绍 课题的背景知识,也就是描述文献研究. 然后提出现在的问题或缺陷在哪里, 作者是如何进一步去研究的.
Heat-shock proteins (HSP) are induced when a cell undergoes various types of environmental stresses like heat, cold and oxygen deprivation. They are involved in a variety of biological functions, such as protein folding, translocation, and immune presentation. (中间添加具体文献研究结果, 然后转入现在的问题是什么)
However, the exact mechanism of how they exert their biological functions remains unclear. In this study, we carried out kinetic experiments to investigate the conformational changes in the structure of HSP’s substrates.
另一种是直接从描述研究的课题的意义下手, 然后阐述作者是如何去研究的. 比如:
Early diagnosis is critical in cancer treatment and cure. In the case of breast cancer, the survival rate was increased dramatically when therapeutic drugs were administered in the early stages of the cancer. (中间添加具体文献研究结果)
To address the need for early diagnosis of breast cancer patients, we have developed two sensitive and specific immunoassays to qualify protein Y activity and protein Y concentrations in both urine and plasma.
