分析 全文大意:
你曾经想过为什么狗是人类最好的朋友吗?狗和人类之间的紧密关系是什么样子的?日本科学家长泽美穗的一项新研究似乎找到了答案.它与一种叫拥抱化合物的东西有关.这种拥抱化合物还有另外一个更科学的名字--催产素.催产素是血液里含有的一种能促进拥抱的物质.例如当母亲给新生儿哺乳时催产素水平增高.根据长泽美穗的研究发现当我们注视着狗的眼睛时,催产素的水平也会增高.人类和狗一起工作接近3万年的历史.为了更好的理解催产素是怎样在狗与人类之间起作用的,长泽和他的团队做了一个实验.他们检测了狗和人类之间的催产素水平,然后让他们在一个房间里彼此之间进行交流.在房间里人类抚摸狗,与狗交流,注视着狗的眼睛.然后再次检测他们的催产素水平.研究者发现人类和狗在交流之后,催产素水平都更高了.然而,人与狗仅仅注视,没有抚摸或说话时催产素水平最高.人类注视狗的眼睛越长会产生更多的催产素.长泽在人与狼之间做了同样的实验,但没有给出相同的结果.
解答 答案:
52.B 细节理解题 根据第一段A new study by Japanese scientist Miho Nagasawa seem to have found answer(日本科学家长泽美穗的一项新研究似乎找到了答案)可知,and it has to do with something named the cuddle(拥抱)chemical应意为"答案与一种叫拥抱化合物的东西有关"代指前面出现的"answer"一词.故选B.
53.A 细节理解题. 根据第二段中The cuddle chemical has another,more scientific name:oxytocin(拥抱化合物有另外一个更科学的名字--催产素)及第三段中In order to better understand how the cuddle chemical worked between dogs and humans,Nagasawa and his team did an experiment.(为了更好地了解狗与人之间的催产素如何起作用,长泽和他的团队做了一个实验)可知,做实验是为了了解狗与人之间的催产素如何起作用.故选A.
54.A 细节理解题. 根据第四段中However,levels were the highest in the humans and dogs that simply looked into each other's eyes,without much petting or talking.(然而,人与狗仅仅注视,没有抚摸或说话时催产素水平最高)可知,当人与狗注视时催产素水平最高. 故选A
55.D 推理判断题. 根据文章最后一句Nagasawa did the same experiment with humans and wolves(狼),but it did not give the same results.(长泽在人与狼之间做了同样的实验,但没有给出相同的结果)可知,人与狼之间有紧密关系是不可能的,故选D
