[解析]
(1)C.细节理解题.根据文章第一段第二句The finding suggests a revision of history﹣ the everyday lives of prehistoric women were filled with hard labor,rather than just sitting at home doing lighter tasks while the men struggled and fought for life(研究发现史前妇女的日常生活充满了艰辛劳作,而不是男性为生活而辛苦劳作时,她们坐在家里做清闲的工作).得知研究发现史前女性所从事的体力劳动和男性一样艰苦.故选C.
(2)A.推理判断题.根据第三段第一句Previous studies only compared female bones to contemporary male bones,the researchers said﹣and that's a problem,得知问题是:"此前的研究只是将女性骨骼和现代男性骨骼对比",这种方法很可能低估了女性的工作强度,可以推断出缺乏比较.故选A.
(3)C.词义猜测题.根据第三段第一句后半句because the response of male bones to stress and change is much bigger than that of women.得知男性骨骼相对于女性骨骼来说对压力作出的反应更明显,前后在对比the response of bones to stress.故选C.
(4)D.推理判断题.根据最后一段最后一句话Prehistoric women,the researchers found,had arm strength 11﹣16 percent stronger than those of modern rowers,and 30 percent stronger than those of non﹣athletes(史前妇女的胳膊强度比现代人的胳膊强度强壮11﹣16%,比现代非运动员强壮30%).得知研究发现史前女性比现代女性更强壮.故选D.
