分数及百分数的用法
1. 分数词的用法
英语分数词由基数词和序数词组成。分子用基数词，分母用序数词，若分子大于“1”，则分母要用复数。如：
Three quarters of the students have passed the exam. 四分之三的学生考试及格了。
The WTO cannot live up to its name if it does not include a country that is home to one –fifth of mankind. 如果世贸组织不能容纳占世界人口五分之一的国家，那它就算不上世界贸易组织了。
2. 百分数的用法
百分数由“基数词+percent”构成。如：
With production up by 60 percent, the company has had another excellent year. 因为产量提高了60%，所以公司那年又取得了很好的效益。
About 60 percent of the workers in this company are young people. 这个公司约60%的工人是年轻人。
