iridescent中文歌词 1 A hundred years ago this week, a giganticexplosion ripped (撕裂) open the day y above a forest in western Siberia, leaving ascientific riddle that endures to this day.
2 A dazzling light pierced the heavens,followed by a shock wave as strong as 1,000 atomic bombs. The explosionflattened 80 million trees across an area of 2,000 square kilometers. Thefireball was so great that, a day later, Londoners could read their newspapersunder the night sky. What caud the so-called Tunguska Event, named after thenearby Podkamennaya Tunguska river, still remains a mystery.
3 Experts suspect it was a rock that, aftertraveling in space for millions of years, was destined to crash to Earth atexactly 7: on June 30, 1908. This possibility worries scientists.“Imagine an unspotted asteroid (小行星) hitting a significant chunk(块) of land ... a
nd imagine if that area, unlike Tunguska, werepopulated,” the British science journal Nature mented recently.

4 But no fragments of the “rock” have everbeen found. Finding such evidence would be important, for it would increa ourknowledge about the risk pod by dangerous Near Earth Objects (NEOs), sayItalian rearchers Luca Gasperini, Enrico Bonatti and Giuppe Longo. When thenext Tunguska NEO approaches, scientists will have to decide whether to try todeflect (使偏转) it or blowit up in space.
5 However, veral rival theories for theTunguska Event exist. Wolfgang Kundt, a professor at Germany's Bonn University,believes the Tunguska Event was caud by a massive escape of 10 million tonsof methane(甲烷)-rich gasfrom deep within earth's crust. Some people hold that the explosion was caudby an alien spaceship crash, or a black hole in the univer.

Twenty-five years ago a young British mancalled Mark Ellingham decided that he wanted a change of scenery. So he went toAustralia, stopping off in many countries beween. He also decided to writeabout the experience and produced a guide for other travelers making similarjourneys.
In 1970, British airports were ud by 32million people. In xx, the figure was 216 million. In 2030, aording togovernment forecasts, it will be around 500 million. It’s a growth driven bythe emergence of low cost airlines, offering aess to all parts of the worldfor less than ?100.
This has made a huge contribution to globalwarming. One return flight from Britain to the US produces the same carbondioxide (二氧化碳)as a year’smotoring (驾车). A returnflight to Australia equals the emissions (排放)of three average cars for a year. And the pollution is relead at aheight where its effect on climate change is more than double that on theground.
Mark Ellingham built his business onhelping people travel. Now he wants to help people stop – at least by air.
四级英语文章 He is calling for a ?100 green tax on allflights to Europe and Africa, and ?250 on flights to the rest of the world. Healso wants investment to create a low-carbon economy, as well as a halt to airportexpansion.
Mark Ellingham’s mitment is importantbecau his readers aren’t just the sort of young and adventurous people whowould happily jump on a plane to spend a weekend exploring a foreign culture.They are also the sort of people who say they care about the environment. It'sa debate that splits people down the middle.
The tourist industry has responded byoffering offtting (补偿) schemes. A small increa in the price of a ticket is ud toplant trees.
But critics say that it is not enough tojust be carbon neutral. We should be actively cutting back on puttinggreenhou gas into the atmosphere. And for the average person, making aplane journey will be his or her largest contribution to global warming. It maybe good to repair the damage we do. But surely it is better not to do the damagein the first place.
