我今天考到了一篇新的阅读,构筑verbal基础实在太差。。。
讲的是 spray sea water into the air to cool down temperature
一共有三段,第一段讲 二氧化碳多,引出这个主题喷海水降温。
第二段讲 这个作用原理,什么大水珠小水珠的,蒸发不蒸发的,看!不!懂!
第三段讲 忘了。。。对不起。。。
(谷歌出来的内容,类似于第一段):It should be possible to counteract the global warming associated with a doubling of carbon dioxide levels by enhancing the reflectivity of low-lying clouds above the oceans, according to researchers in the US and UK. John Latham of the National Center for Atmospheric Research in Boulder, US, and colleagues say that this can be done using a worldwide fleet of autonomous ships spraying salt water into the air.
作用原理(我自己谷歌的)
The evaporating water, Ace said, would cool the Earth in multiple ways: First, the sprayed droplets would transform to water vapor, a change that absorbs thermal energy near ground level; then the rising vapor would condense into sunlight-reflecting clouds and cooling rain, releasing much of the stored energy into space in the form of infrared radiation.
