在今天，气象的“脸”已经变得越来越科学了，可是老人们仍津津乐道于一些有关天气气象的通俗的民间智慧，中国人如此，西方人也如此。 Did you know? ◎Sound travels farther before a storm ◎Ropes tighten before a rain. ◎Rainbows are always opposite the sun. ◎City temperatures are almost always 5 - 10 degrees warmer than the surrounding suburbs. ◎Clouds cover two-thirds of the earth. ◎Raindrops fall at speeds between 7 and 18 miles per hour. For centuries, sailor and farmers relied on folklore(民间智慧) to predict(预测) the weather. As modern forecasting techniques became more accurate, most of these old tales were dismissed(不用了). But some have valid(有效的) scientific explanations. Mackerel sky, not three days dry. 天色泛鱼鳞，必无三日晴 注释：Mackerel sky refers to clouds that look like fish scales(鱼鳞). These cirrocumulus clouds(卷积云) are high, rippled(起涟漪的) ice crystals(结晶) that show up in advance of a storm system and may predict rain. When dew is on the grass, rain will never come to pass. 草上露珠闪，告别下雨天 注释：The formation of dew(露珠) requires nighttime cooling(降温). This usually occurs best on cloudless, still(无风的) nights, so the chance of rain is unlikely. Red sky at night, sailor’s delight. Red sky in the morning, sailor’s warning. 晚上天色红，水手乐呵呵；早晨天色红，水手急煞煞。 注释：A red sky is the result of light passing through contaminants(污染物) held close to the earth by high air pressure(气压). These particles scatter away some of the shorter wavelengths(波长) of light (violets and blues), leaving only the longer wavelengths (the oranges and reds). A red sky is a reliable indicator (可靠的预示) of a high-pressure(高气压) system, which generally brings fair weather. A red sky in the morning is the result of sunlight reflecting through clouds moving in from the west, which could bring bad weather. Fish bite best before a rain. 大鱼吃小鱼，天空要下鱼 注释：The drop in barometric pressure(气压) before a storm sets into motion a chain of events(引起连锁反应): Bubbles formed by decaying products(腐烂物) on the lake bottom start to expand, making some of the matter buoyant(有浮力的) enough to rise. As minnows (淡水小鱼) start to feed on the rising matter, larger fish begin feeding on the minnows.实践证明经常访问无忧英语教育网 www.51education.net ,能迅速提高你的英语学习能力!积沙成塔,不断提高! 本站所提供的所有信息仅供学校课堂教学及英语学习者学习研究之用，其著作权归原作者及媒体所有。 |
