春雨贵如油的英语是Spring rain is as expensive as oil。
雨是一种自然现象，是从云中降落的水滴。陆地和海洋表面的水蒸发变成水蒸气，水蒸气上升到一定高度之后遇冷液化成小水滴。这些小水滴组成了云，它们在云里互相碰撞，合并成大水滴。当它大到空气托不住的时候，就从云中落了下来，形成了雨。
雨的成因多种多样，它的表现形态也各具特色，有毛毛细雨，有连绵不断的阴雨，还有倾盆而下的暴雨。
雨水是人类生活中最重要的淡水资源，植物也要靠雨露的滋润而茁壮成长。但暴雨造成的洪水也会给人类带来巨大的灾难。
随着人类工业化发展，工业废气大量排放到大气中，形成酸雨，对生态环境造成重大不利影响，导致建筑腐蚀。
英文版：
Rain is a natural phenomenon, a drop of water falling from a cloud. The water on the surface of land and sea evaporates into water vapor, which rises to a certain height and then liquefies into small water droplets when it is cold.
These small water droplets form a cloud. They collide with each other in the cloud and merge into large water droplets. When it is too big to hold the air, it falls from the clouds and forms rain.
The causes of rain are various, and its forms of expression are also distinctive. There are drizzle, continuous rain and torrential rain.
Rainwater is the most important fresh water resource in human life, and plants thrive on the moisture of rain and dew. But the flood caused by rainstorm will also bring great disaster to human beings.
With the development of human industrialization, a large amount of industrial waste gas is discharged into the atmosphere, forming acid rain, which has a significant adverse impact on the ecological environment, leading to building corrosion.
