标点符号

空格问题：中文几乎从不需要使用空格，但英文中标点符号和下一个单词之间需要有一个空格，看似很简单的规则，但很多人的英文文章因为没有空格，写出来让人看着觉得憋得慌。

逗号问题：两个独立的句子之间不能用逗号，要么用句号，要么用分号。有些人写东西很随意，逗号一路打到底，不知道段落到底是什么结构。

书名号问题：英文中没有书名号！不要笑，就是有人会在 Word 中给一本书或论文打上书名号。如何在正文中提一本书或论文呢？正确的方式是用斜体或者引号。如果文中要提到数十篇文献，那么我建议还是用参考文献的方式吧，比如 Xie (2009)。

跑题提一下 LaTeX 引号问题：我注意到不是所有 LaTeX 用户都知道引号的正确写法（这让我有点吃惊），它不是""，而是 ''，否则，编译出来的文档两个引号的方向是一样的。LyX 用户敬请忽略本段，直接打引号的话它会自动生成正确的引号代码。

few 和 little

它们本身表示否定意思：几乎没有。而不是有一些 / 一点。如果要表达后者的意思，那么加上 a。阅读的时候尤其注意。
