Felicia Brittman通过编辑200多篇中国理工科研究生撰写的英文论文，观察和总结了一些最常见的语法错误和表达习惯问题。她在文章中对这些问题举例说明，并给出了示范文本和修改建议。
本系列基于Felicia Brittman的文章 The Most Common Habits from more than 200 English Papers written by Graduate Chinese Engineering Students （www.SciEI.com），将这些易错点一一道来，帮助JDIS用户避免这些问题，提高英语论文的写作水平。
第三节 引子与中心思想的位置
位置问题
PART
01
在句子的开头先陈述目的、地点或者原因，后说中心思想。
中国作者通常会将目的、地点、原因、例子和条件放在句首，做为引出主题的引子。但是在英语写作中，这会降低中心思想的重要性，让读者认为作者闪烁其词。应该将中心思想放在句子的开头，然后说明地点、原因等。
