　　CCDD 　　分析：　　木星1994年7月遭到彗星的撞击而发生爆炸，这被地球上的科学家观察到了。如果地球被彗星撞到会发生什么呢？文章预测了2094年彗星的碎片撞击地球的南半球带来的后果。1.根据第三段“CitiesontheAfricancoastaretotallydestroyed”和第四段“temperaturesaroundtheworldfalltoalmostzero...Warsbreakoutascountriesfightforfood.”可知，A、B、D正确，人类不会灭绝，故选C。2.根据最后一段“Coulditreallyhappen?InfactithasalreadyhappenedmorethanonceinthehistoryoftheEarth.Then65millionyearsagotheysuddenlydisappeared.ManyscientistsbelievethattheEarthwashitbyaspacefragment.Thedinosaurscouldn’tsurviveinthecoldclimatethatfollowedandtheybecameextinct.”可知，作者提到恐龙是为了预言地球未来的命运。故选C。3.根据最后一段“Thedinosaurscouldn’tsurviveinthecoldclimatethatfollowedandtheybecameextinct.Willwemeetthesameend?”可知，作者用恐龙灭绝的历史来警告未来可能发生的灾难。故选D。4.文章讲述的是未来可能发生的灾难，根据第一段“theexplosionswerewatchedbyscientists...”可知，文章与科学有关，作者提出了几个疑问，说明是未被证明的预言、推测，不属于论文的范畴。A恐怖故事；B新闻报道；C研究论文；D科普读物。故选D。　　考点：　　科普类短文阅读
