It was not“the comet of the century”experts predicted it might be Nevertheless,Kohoutek
has provided a bonanza of scientific information.It was first spotted 370 million miles from Earth,by an astronomer who was searching the sky for asteroids,and after whom the comet was named Scientists who tracked Kohoutek the ten months before it passed the Earth predicted the comet would be a brilliant spectacle But Kohoutek fell short of these predictions,disappointing millions of amateursky watchers,when it proved too pale to be seen with the unaided eye Researchers were delighted nonetheless with the new information they were able to glean from their investigation of the comet.Perhaps the most significant discovery was the identification of two important chemical compounds methyl cyanide and hydrogen cyanide--never before seen in comets,but found in the far reaches of interstellar space This discovery revealed new clues about the origin of comets.Most astronomers a gree that comets are primordial remnants from the formation of the solar system,but whether they were born between Jupiter and Neptune or much farther out toward interstellar space has been the subject of much debate If compounds no more complex than ammonia and methane,key components of Jupiter,were seen in comets,it would suggest that comets form within the planetary orbits. But more complex compounds,such as the methyl cyanide found in Kohoutek,point to formation far beyond the planets;there the deep freeze of space that kept them unchanged
Why was Kohoutek referred to as“the comet of the century”?________
选项
A、It was thought to be extremely old
B、It passes the Earth once a century.
C、Scientists predicted it would be very bright.
D、Scientists have been tracking it for a century.
答案
C
解析
依据是文章第四行“Scientists who tracked Kohoutek the ten months before it passed the Earth predicted the comet would be a brilliant spectacle”由于科学家预测这颗彗星可能会比较亮,因而引起了许多业余天文爱好者的极大兴趣,这显然是该彗星被誉为“the comet of the century”的原因,因此正确答案是C。
