嗨，大家好！
我们知道，change的意思有“改变，变化”。rest的意思有“休息，放松”。“as…as…”的意思是“和……一样……”。
那大家猜猜看，习语a change is as good as a rest是什么意思呢？
a change is as good as a rest的意思是“you can get as much good from changing the work you do as from having a rest”，即“改换工作益如休养，换个环境等于休息”。
这句习语源于维多利亚时代。1825年，在《Christian Gleaner and Domestic Magazine》中，有这样一段话：
It goes as, “Change of work is as good as play.” It may have originated in response to, “All the work and no play makes Jack a dull boy”.
上面这段话表明了，change of work is as good as play可以看作是“all the work and no play makes Jack a dull boy”的对照组。change of work is as good as play就是习语的a change is as good as a rest前身。
“all the work and no play makes Jack a dull boy”的意思是“工作不玩耍，聪明孩子也变傻”。
而在1857年的一首诗中，a change is as good as a rest这句习语首次出现在文本中：
Ye children of Fashion and Wealth,
With countless indulgences blest,
Remember that indolence preyeth on health
A change is as good as a rest.
例句：
As the saying goes, a change is as good as a rest.
就像一句古话说的，改换工作益如休养。
Mary drifts from one job to another. A change is as good as a rest.
玛丽无目的地更换工作。改换工作益如休养。
以上就是今天所学内容，你学会了吗？
