有读者问： 《英语世界》某期中有一句：
(1)There are 14 eminent scientists on this commission, ten from Italy and one each from the United States of America, Great Britain, Germany, and Belgium.
我对one each不大理解，查词典也未找到相关的例句。
one each的意思是“各有其一”，one each from the United States of America, Great Britain, Germany, and Belgium即意为“美、英、德、比各有其一”。“数词+each”结构在英语中不乏其例，再如：
(2)The plants, one each in Shanghai and Guangzhou, produce 1.3 million tubes a year.
(3)Thirty-nine Japanese companies, four US firms and one each from Germany, Switzerland and France, were given the same permission on Monday by the Japanese Ministry of Finance.
(4)The players have been drawn to play in the tournament by the International Badminton Federation （IBF）from its top men and women rankings. They include eight entries each from China, Denmark and England, four each from Malaysia and South Korea, two from Sweden, one each from Australia, and 18 from the host country.
从语法结构来讲，each在此一般皆被认为是不定代词，作同位语用（也有人认为是副词，作状语用）。上述“数词+each”皆后接一个介词短语。其实亦可独立运用，例如：
(5)They sell oranges, two pence each .
(6)Biscuits! Can we have two each , Mum?
