先看這2個詞組的解釋：
year after year
年年；每年
every year for many years
year by year
一年一年地；每年；年復一年
as the years pass; each year
它們的解說不同，說明它們看起來都有：“逐年，一年一年地”含義，但是，使用場合完全不同，year after year表示的是年年重複，毫無變化；year by year表示的是雖年年發生，但是年年都有變化發生。另外，year換成 day時，含義和區別是相類似的。看看例句，來琢磨它們的使用場合吧：
You keep on amazing me, year after year, the same old ways.
