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 three 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 down 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 stopped 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/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。
There's a post box every 500 metres. 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。
every fourth year =every four years
every other day 每隔一天, 你要硬逼多一种,也可以是every two days或是every second day,但这不常用.
给你一个例句,加深印象:
He comes here every two days (every second day). 他每两天(每隔一天)来这儿一次。
every fourth year
每隔三年
every four years
每四年
每隔一天
every second day
every other day
every fourth year:每四年,
every four years : 每隔三年
每隔一天: every two days
every four years和every fourth year 是一样的。
每隔一天:every two days ,every other day.
