恐龙为什么灭绝翻译成英语写一篇作文

it is believed that the extinction of dinosaur is associated with an asteroid impact .
A large asteroid enters the atmosphere at extremely high speed, glowing red hot as the friction of the air turns it into a fiery cannon ball. Its impact with the ground results in a massive explosion, vaporizing the space object and launching perhaps over a trillion tons of gas, ash and rock dust into the atmosphere.
If the asteroid is big enough— about three kilometers (two miles) in diameter— the energy released by the impact would hurl enough debris into space to envelop the Earth in a rain of fire.

The ejected debris would re-enter the atmosphere like billions of meteorites, raining burning balls of fire back to Earth in a giant display of planetary fireworks. The brilliant glow from these billions of fireballs would ignite forest fires across the globe, generating vast, thick clouds of smoke and soot.
These clouds may have initially been thick enough to shut down photosynthesis for a year, and perhaps they blocked the sun long enough (several years) to cause major global cooling.The prolonged period of darkness that shrouded the planet caused the plants to die, breaking the food chain and starving the animals. Many of them, including the dinosaurs, died out.

我爱，因为有你在，我念，因为彼此在等待，经年，红尘渡口，那份相约不会改变，山无棱，天地合，才敢与君绝。

采摘文字的灵性，编织最美的风情，我在尘音中起舞，君若有灵犀，可否琴瑟相和。

最美的年华，你静谧的眼眸不曾有丝毫淡漠，其实不管山山水水，你始终都在，在我转身随处可寻的地方，微笑的看着我。

昨夕，写惯了凄美的故事，那些无奈在挥笔间似乎已远离，今夕，时光浅短，只想用心来告诉你，承载你的爱，空气也如此缠绵，爱，没有过多的言语，一份厮守，一份坚定，足以！
