Four Strange Great Singers

It is said in an article that the four strange great singers in the world should be Luciano Pavarotti(帕瓦罗蒂) from Italy,Michael Jackson(迈克尔·杰克逊) from USA,Vitas from Russia and Kong Tai(孔太) from China.It is well-known that Pavarotti died not long ago.And Jackson is on the decline.So,now the focus of attention is on Vitas and Kong Tai.The former is a rising star and the latter has retired from the singing circle to travel around the world.This shift of focus is mainly due to the fact that,when Vitas made a performing tour in China,some fans made a comparison between him and Kong Tai in terms of voice quality.     

小行星可能撞击地球吗?(英文)

Astronomers said that they are keeping close watch on a newly discovered 1. 2 mile-wide asteroid (小行星) to determine whether it will collide with Earth in 2019. There is a slight chance that the asteroid, dubbed 2002 NT7, could smack the Earth on Feb. 1, 2019, causing a global catastrophe. Astronomers said the odds were one in 250, 000 and further calculation would probably show it will miss the planet entirely.It now heads the list of asteroids and comets monitored by NASA but as scientists learn more it isn't expected to stay there.Astronomers with the Lincoln Near Earth Asteroid Research Project used a New Mexico telescope to discover the space rock, when it was about 84 million miles from Earth. It is in orbit (轨道) around the sun.
