D.Archaeologists.语篇解读:本文是一篇说明文。尽管大多数犯罪现场都含有人的毛发,但是细胞核DNA往往缺失,阻碍了案件的侦破。为此,法医界也在主动开发DNA分析以外的身份识别技术。美国联邦平安试验室近日提出了一种方法,将毛发中的蛋白标记物与DNA分析相结合,可实现更精确的人类身份识别。答案及剖析:1.D主旨大意题。依据全文可知,探讨表明,可以通过对人毛发中的蛋白质的分析来确定一个人的身份。故选D项。2.A细微环节理解题。依据第三段中Afterbonesandteeth,hairisinfactoneofthemostresistantstructuresofthehumanbody.可知,对骨骼和牙齿的分析数据最为牢靠。3.D细微环节理解题。依据第五段中Themethodnotonlyallowsforhumanidentificationbutitcanalsorevealhowoldthesampleisandwhatregionitcomesfrom,sothatwecandistinguishbetweencurrentandancientsamples.可知,这一方法不仅可以显示个人身份,还可以显示标本的来源地。4.D细微环节理解题。依据最终一段中Itwillalsobeofgreatuseinarchaeology.可知,这一发觉在考古学探讨方面价值极高。故选D项。Ⅱ.七选五Lifegettingyoudown?Learntobounceback“Thatwhichdoesnotkillusmakesusstronger.”Nietzschesaid.Thereareanumberofwaysthatcangetusthroughtoughtimes,helpustobouncebackandmakeushappier.1.

4.C“affordtodo”担当得起某事;“argue”争辩;“decidetodosth”确定做某事;“happentodo”碰巧做某事;依据句意可以推断出答案是C。5.D依据此段中的“Sincethen”,上半段是造成作者爱上摔跤的缘由之一。所以,作者每周六早上去看哥哥摔跤,这是最符合逻辑的。6.A上文提到“摔跤基本是男人的运动”,再加上作者去看哥哥摔跤,所以最符合逻辑的是A。7.A阅读下文,可见作者是很喜爱摔跤这项运动的;此句“自此以后,摔
