解题思路：名词作定语一般用单数，但也有例外．
1)用复数作定语．
如：sports meeting运动会
students reading-room学生阅览室
talks table谈判桌
the foreign languages department外语系
2)man，woman，gentleman等作定语时，其单复数以所修饰的名词的单复数而定．
如：men workers，women teachers，gentlemen officials
3)有些原以s结尾的名词，作定语时，s保留．
如：goods train(货车) arms produce武器生产
customs papers海关文件 clothes brush衣刷
4)数词+量词用连字符结合成一个词作定语时，这个量词一般保留单数形式．
如：two-dozen eggs两打鸡蛋/(二十四个鸡蛋)
a ten-mile walk十里路
two-hundred trees两百棵树
a five-year plan一个五年计划
