year after year 与year by year都作有区别吗

Question

如题所述

Answer 1

两者均可表示“年年”，但含义和用法均有区别：
year by year 通常用作状语，且含有逐渐(gradually)转变的意思；
year after year 可用作状语，有时也可用作主语或宾语，它通常暗示时间之长久(for many many years)。
比较：
He sent money year after year to help the poor. 他年年送钱帮助穷人。
Prices tend to rise year by year. 物价总是一年一年地往上涨。

他们的基本含义相同，但使用场合不同。year after year 含有“年年重复，毫无变化”之意。而year by year含有“年年发生变化”之意。
例句：

Year after year I have a birthday present from my parents. 我年年都从父母那里得到一份生日礼物。
Year by year we grow a little older. 我们会逐年变老一些。

They liked the cool wet weather there and their number increase year by year. 它们喜欢那儿凉爽而潮湿的气候，因此它们的数目逐年增加。

上面的解释也适用于day after day 和day by day:

Day after day the mouse came back. 老鼠天天都回来。

Day by day the situation is improving. 情况每天都在改善着。

year by year 强调每年都有变化 ,渐变性
而year after year 只强调动作的重复 ,重复性
如：My parents become older and older year by year so I go to visit them year after year .我的父母年年都在变老,所以我每年都要去看他们
