water rationing (n.) 限水
限水的英文可不是limit water唷！必须使用water rationing这个惯用语，ration是「定量配给」的意思，而限水就是指将水库的水做限制、定量供给，因此英文使用water rationing。
e.g. If there is still a lack of rain, third-phase water rationing may be launched soon.
(如果还是没下雨的话，第三阶段限水马上就会实施)
e.g. The Shihmen Reservoir, which supplies water to some parts of New Taipei City saw a record-low water level yesterday.
(供应新北市一些地区水量的石门水库昨天的水位创新低了) 取自Taipei Times
补充：
phase (n.) 阶段 → first-phase = phase one 第一阶段
reservoir (n.) 水库
water level (n.) 水位
drought (n.) 干旱
inundate (v.) (洪水等)泛滥；如洪水般扑来
inundate 现在很常被用来形容某事如洪水般扑来，使人无法招架
inundate sb/sth with sth (主动式用法)
sb be inundated with sth (被动式用法)
e.g. The river inundated the fields with three feet of water. 那条河使田里洪水泛滥到三英尺高
e.g. After the address, the speaker was inundated with questions. 讲者在演说之后收到一连串的问题，无法招架
overwhelm (v.) 淹没；压倒
这个字也很实用，可用在具体或抽象的事物上
e.g. Despair overwhelmed you. 绝望将你淹没了 (这里的淹没是抽象的意涵)
补充：overwhelming (adj.) 压倒性的
tread water 停滞不前
tread是「踩；踏」的意思，tread water是指(游泳)踢水、踏水，它还有另一个引申义是在原地踏水、停滞不前的意思。通常如果是表达「停滞不前」，用进行式居多。
e.g. The sales didn’t increase at all. The company is only treading water.
(销售额完全没增加，公司状态一直停滞不前)

throw/pour cold water on sth 泼冷水
没错！泼冷水直翻就对了，要注意的是，中文是说对某人泼冷水，但英文通常是对某「事物」泼冷水。
e.g. Peter threw cold water on Kelly’s joke. Peter对Kelly的笑话泼冷水

(我在新公司好不自在)
water off a duck’s back (批评)对人没有影响；耳边风

e.g. Our criticism of his new plan is like water off a duck’s back.
