1、在中学英语课本中，我们常遇到 every 与数词、other、few 和表示时间、空间或距离的名词搭配，合起来表示“ 每隔”的一些表达。现将这些表达归纳如下，供同学们学习时参考。一、表达方法：1. “every基数词 (大于或等于 2)复数名词” 意思是“每”。例如：The old man went to hospital every five days. 那老汉每五天每隔四天就去看一次病.There are buses to the station every ten minutes.每十分钟每隔九分钟就有公共汽车去火车站.We hand in our homework every thre
2、e days. 我们每三天每隔两天交一次作业。2. “every序数词 (大于或等于 2)单数名词”意思是“每第”。例如：The Olympic Games are held every fourth year. 奥林匹克运动会每四年每隔三年举办一次。He comes to see his uncle every third week.他每三周每隔两周来看望他的叔叔。3. “every other 基数词(大于或等于 2) 复数名词” 意思是“每隔”。例如：I have to work out every other two days. 我每隔两天就要作一次运动。I had to sit do
3、wn and rest every other four minutes. 我每隔 4 分钟就得坐下休息。4. “every other 零基数词(等于 1)单数名词” 意思是“每隔一”。例如：Take this medicine every other day. 这药每两天每隔一天服一次。Please write down these new words on every other line. 请把这些生词隔行写下来。5.“every few 复数名词 ” 意思是“每隔几” 。例如：He came to see me every few days. 他每隔几天来看我一次。He stoppe
4、d and turned around every few meters. 他每走几步就停下来向四周看一看。二、译法：1. 从上面的例句中可以看出，在“every基数词(大于或等于 2)复数名词； every序数词(大于或等于 2)单数名词 ”中，在表示空间一点和时间时，every 既可译成“每”，也可译成“每隔”。译成“每隔”时，汉语和英语不同，要在英语所给数字中减去一，即（ n-1） ，但表示距离时，译成“ 每”或“每隔”，在意义上差别不大，英汉互译在数字上则是一致的。例如：The doctor told him to take the medicine every four hours/
5、every fourth hour.医生让他每四个小时 每隔三小时吃一次药。I write to him every two weeks/every second week. 我每两周每隔一周给他写一封信。Theres a post box every 500 meters. 每每隔 500 米就有一个邮箱.We were asked to plant a tree every twenty meters on both sides of the road.要求我们在马路两旁每隔每 20 米栽一棵树。Change the oil in the car every 5,000 miles. 每行
6、 5000 里给汽车换一次油。2. 当 every 所修饰的数字大到一定程度时，译成“每”或“每隔”，意义上差别不大。例如：The doctor visits his mother every hundred days. 这位医生每/ 每隔一百天去看望他母亲一次。三、转换：He goes to town every two days/every second/other day. 他每两天每隔一天进城一次。Mary goes to see her grandparents every three days/every third day/every other two days.玛丽每三天每隔两天去看望她祖父母一次。四、注意事项：every 和 each 虽为同义词，但在表达“每隔”时，不能用 each 来替代 every补充：每天去是 every day每隔一天是 every two days每隔两天当然是 every three days 或 every third day
