世界知名、顶尖跨国公司的首席执行官(CEO)约有四分之一为印度裔籍人士担任。英语是西方世界的通用语言，我们处于相对劣势。究其原因，其中之一可以说是我们的英语单词词汇量掌握不够。从小学到大学的英语教育普遍关注语法，极少关注词汇量拓展。众多英语培训机构注重考什么，怎么考，极少提供英语单词的系统拓展和培训。同学往往只能死记硬背单词书，学习效率一般相当低下。

这里给出几个“词以根记”提升英语单词学习效率的例子，更多例证参见公司网页和教材。
aggregate, congregate, segregate, egregious, gregarious 等单词同含有英文词根greg- (群、集、批等含义)，结合前缀ad-, con-, se-, ex-, 后缀 -ate, -ious, -arious等，同学很快就能理解、掌握它们的词意，并记忆牢固。
