17.C尽管美国各州在面积和人口方面有明显的差异，但是它们有许多共同之处。

［考点］固定用法

【精析】Cdespite为介词，表示尽管，后面接名词或名词短语，符合此处的句子结构。although和though为连词，其后一般要跟句子，不符合题意。have…incommon为固定搭配，意为有……共同之处。故选项C为正确答案

42.Sheisalwayswellaheadoftherestoftheclass,whichmakesherparentsveryhappy

43.大多数环境污染问题的存在是因为过去没有采取适当的预防措施

44.B［考点］事实细节题

【精析】B根据第二段第一句Yourtrees'troublemaybeyouyourself.可知，你可能会给树木带来麻烦，也就是说有些树木的麻烦是人类造成的。其余三项均与文章大意不符

45.D［考点］推理判断题

【精析】D根据第四段Themicegivennightmilk,whichcontained10timestheamountofmelatonin…可知，晚上收集的牛奶中褪黑激素含量是白天收集的牛奶的10倍，并没有说在老鼠身上用褪黑激素试验过10次，所以A项错误。根据第二段…moremelatonin,whichhasbeenproventohelppeoplefeelsleepyandreduceanxiety.可知，褪黑激素在晚上收集的牛奶中含量更高，且会让人昏昏欲睡，而不是精力更加充沛，所以B、C两项错误。根据第六段…takingmelatonindrugshasbeensuggested…可知，服用含褪黑激素的药可以帮助睡眠，由此可推知，褪黑激素被用在了安眠药中，所以D项正确。故选D
