晕。还要怎么具体。二者意思是一样的。而且给你例句了。有啥不懂的呢?我就告诉你一句:the olympic games is held every four years(=every fouth year).凭你对奥运会的了解。你应该知道怎么翻译了吧。。一样的。every third year.每三年出现一次的,三年一次的every three years每三年every fourth year =every four years every 与基数词、序数词、other 和few 连用,表示时间或空间的间隔,意为“每……;每隔……”。如: He comes here every three days (every third day). 他每三天(每隔两天)来这儿一次。 You'd better plant a tree every five meters(every fifth meter). 你最好每(隔)5米种一棵树。(树的空间忽略不计) Write on every other line. 隔行写。 every other day 每隔一天 every few days 每隔几天(注意“few”前没有“a”)
