【分析解答题】根据以下材料,回答42-46题
It' s one of our common beliefs that mice are afraid of cats. Scientists have long known that even if a mouse has never seen a cat before, it is still able to detect chemical signals released from it and
 run away in fear. This has always been thought to be something that is hard-wired into a mouse' s brain.
But recently Wendy Ingrain, a graduate student at the University of California, Berkeley, has chal-lenged this common sense. She has found a way to "cure" mice of their inborn fear of cats by infec-ting them with a parasite, reported the science journal Nature.
The parasite, called Toxoplasma gondii, might sound unfamiliar to you, but the shocking fact is that up to one-third of people around the world are infected by it. This parasite can cause different diseases among humans, especially pregnant women--it is linked to blindness and the death of un-born babies.
However, the parasite' s effects on mice are unique. Ingrain and her team measured how mice reacted to a cat' s urine (尿) before and after it was infected by the parasite. They noted that norma
l mice stayed far away from the urine while mice that were infected with the parasite walked freely a-round the test area.
But that' s not all. The parasite was found to be more powerful than originally thought—even after researchers cured the mice of the infection, they no longer reacted with fear to a cat' s smell,which could indicate that the infection has caused a permanent change in mice' s brains.
Why does a parasite change a mouse' s brain instead of making it sick like it does to humans?
The answer lies in evolution. Toxoplasma gondii can only reproduce inside a cat. So the parasite had to develop a way of tricking the mice into getting eaten more easily--thus helping itself go inside a cat--by taking away mice' s sense of alarm.

网考网试题解析:

42参考解析:C[解析]主旨大意题。该篇文章主要讲述了通过实验证明寄生虫对老鼠不再害怕猫而产生的积极影响。A、B、D三项都不符合文章主旨,C项意为“一则关于寄生虫对老鼠产生影响的新故事”,符合文章主旨。所以C项正确。 43参考解析:A[解析】词义猜测题。根据划线词所在句中的“into a mouse’s brain(进入老鼠的大脑)”可知,四个选项中只有root与之搭配合理。A项意为“深深地植入”;B项意为“快速改变”;C项意为“紧密连接”;D项意为“深深地掩埋”。所以A项正确。 44参考解析:B[解析]细节理解题。根据文章第三段最后一句可知.携带寄生虫的老鼠在测试区附近随意行走,而未携带寄生虫的老鼠则远离测试区。所以B项正确。 45参考解析:D[解析]细节理解题。A项(这种寄生虫会使人患奇怪的、致命的疾病),文中第二段最后一句提到,这种寄生虫会使人得不同的疾病,尤其会造成未}H世的婴儿失明或胎死腹中,但并没有说导致奇怪的病,所以A项表述错误。B项(因为存在一些传染,传染性疾病不能完全被治愈),此表述文中并没有提及。C项(被这种寄生虫感染的人的脑结构将会永久性坏死),文中第四段最后有提到,这种感染可能对老鼠的大脑造成永久性的改变,所以此表述错误:D项(这种寄生虫对人类有害,但是对老鼠却无害),根据文章第五段第一句可知,寄生虫能改变老鼠的大脑结构而会致使人类生病,所以此表述正确。 46参考解析:A [解析】观点态度题。A项意为“积极的”;B项意为“主观的”;C项意为“消极的”;D项意为“客观的”。根据文章第四段中的“The parasite was found to be more powerful than originally thought”可知,作者对此实验的态度是积极的。所以A项正确。 查看试题解析出处>>
