英语分数的表示法： 用“基数词＋序数词”表示，分子用基数词，分母用序数词。分子除用 one 外，也可用 a ；如果分子大于 1 ，分母要用复数形式。Two thirds of the students have passed the exam.  三分之二的学生考试及格了。

注意： 1 ／ 2 不能说 a （ one ） second ，而要说 a （ one ） half 。 1 ／ 4 和 3 ／ 4 可以说 a （ one ） fourth 和 three fourths ，但常用 a quarter 和three quarters 表示。 若它们在句子中作主语，则谓语动词是用单数还是复数取决于名词，即与分数所修饰的名词保持一致。 About two thirds of the students attend the meeting ．大约 2 ／ 3 的学生都参加了会议。

6. Hang on a minute!

通常用来表示让某人等一下。e.g. Hang on! I’ll be back in a minute.

朗读时，将每三位数看做一个单位，依次为billion ， million ， thousand 。每个单位按照百、十、个位向下读，其中百位到十位之间要加入 and 。e.g. 729 ： seven hundred and twenty nine.

6,500,431,729 ： six billion five hundred

million four hundred and thirty one

thousand seven hundred and twenty nine.

在英语中，对于万以上的数字，我们改如何表达呢？这就要记住英语数字读法特点。以下面一个数字为例：

6 ， 500 ， 431 ， 729

hundredthousandmillionbillion

注意每三个数为一个单位，按照百、十、个向下读。
