year after year

year after year 年年，每年

【例句】 

◆We used to go to the beach for a holiday year after year. 过去我们每年都去海滩度假。   

◆Year after year, however, we are increasing the number of practice tests．然而，年复一年，我们一直在增加测验的数量。（江苏高考）

【辨析】year after year和year by year

year by year意为”一年一年地，每年”， 常表示逐年变化：因此，准确地说，year after year表示”年年（重复）”的意思，而year by year表示”逐年（变化）”的意思。如：My son grows taller year by year．我儿子长得一年比一年高了。 Year after year my son visits his grandparents in summer holidays．我儿子年年暑假去看望他的祖父母。
