辨析：principal & principle，提高新加坡AEIS考试录取率

　　想要攻克AEIS考试，就得先过了词汇这一关。AEIS阅读和AEIS写作对AEIS词汇量要求极高：阅读中的词汇往往不太友好;作文中用好词才能有高分。但AEIS英语考试本身就是片词海，即使对于Native Speaker来说，背AEIS单词也不是件易事。下面新加坡AEIS考试培训中心为大家带来AEIS词汇辨析：principal & principle。

　　The words principle and principal are pronounced in the same way but they do not have the same meaning.

　　另一方面，Principal常被用作形容词，表示“主要的或最重要的”，比如：

　　one of the country’s principal cities

　　Principal同样可以用作名词，用来指组织或者团体中最高等或者最重要的人，比如“副校长”。Principal同样也可以用来指“一定量用来投资或借贷的钱(这部分钱需要支付利息)“，比如“贷款的本金”
