单选题 It turns out that men's brains may literally be wired differently than those of women. Researchers say the differences could explain why the sexes seem more suited to certain types of tasks than their counterparts. For example, women seem to be hardwired for multitasking.
Using imaging techniques, researchers at the University of Pennsylvania found men tended to display neural activity in one hemisphere of the brain for certain activities, while in women the activity bounces across hemispheres. "These maps show us a stark difference and complementarity in the architecture of the human brain that helps provide a potential neural basis as to why men excel at certain tasks, and women at others." said Ragini Verma, a PhD in the department of Radiology at the University of Pennsylvania.
Past studies have shown sex differences in the brain, but the neural wiring connecting regions across the whole brain that have been tied to such cognitive skills has never been fully shown in a large population, the researchers said. Researchers found that in the cerebrum, the largest part of the brain, females displayed greater connectivity between the left and right hemispheres. Males, on the other hand, displayed greater connectivity within each hemisphere. By contrast, the opposite prevailed in the cerebellum, the part of the brain that plays a major role in motor control, where males displayed greater inter-hemispheric connectivity and females displayed greater intra-hemispheric connectivity.
These connections likely give men an efficient system for coordinated action, where the cerebellum and cortex participate in bridging between perceptual experiences in the back of the brain, and action, in the front of the brain, according to the authors. The female connections likely facilitate integration of the analytic and sequential processing modes of the left hemisphere with the spatial, intuitive information processing modes of the right side.
The findings meshed with other University of Pennsylvania studies in which females outperformed males on attention, word and face memory, and social cognition tests. Males performed better on spatial processing and sensorimotor speed. Those differences were most pronounced in the 12 to 14 age range. "It's quite striking how complementary the brains of women and men really are," said Dr. Ruben Gur. He further pointed out detailed connectome maps of the brain will not only help us better understand the differences between how men and women think, but it will also give us more insight into the roots of neuropsychiatric disorders, which are often sex related.

单选题 Based on the first 2 paragraphs, which statement is true?

A.Men's brains are the same as women's.
B.The two hemispheres of brain work separately.
C.Women are better at multitasking work than men.
D.Men perform better than their female counterparts in all fields.

【正确答案】 C

【答案解析】[解析] 细节题。由第一段第一句“It turns out that men's brains may literally be wired differently than those of women.”可知：男士与女士的脑子结构并不相同，这与A项的内容不相符。由第二段第二句“These maps show US a stark difference and complementarity in the architecture of the human brain...”可知：人的左、右半脑具有一定的互补性，不是独立分别发挥作用，这与B项内容不相符。由第一段第二句“Researchers say the differences could explain why the sexes seem more suited to certain types of tasks than their counterparts.”可知：男女各有自己擅长的工作，这与D项内容不符。由第一段第三句“...women seem to be hardwired for multitasking.”可知：女性似乎擅长多任务处理，这与C项内容相符。所以本题正确答案是C。

D.Cerebellum and cortex.

单选题 According to the study, which of the following is highly possible?

A.Girls perform better than boys in a word dictation test.
B.Generally speaking, boys are better at geometry than girls.
C.Boys can remember and recognize people better than girls.
D.Generally speaking, boys have longer concentration span than girls.

【正确答案】 B

【答案解析】[解析] 推理题。由第五段第一句“...females outperformed males on attention, word and face memory, and social cognition tests.”可知：女性擅长集中注意力，单词记忆，识别人脸等活动，这与A项、D项和C项内容不符。由第五段第二句“Males performed better on spatial processing and sensorimotor speed.”可知：男性擅长空间构造，所以男孩子相对而言要比女孩子要擅长几何，这与B项内容相符，所以本题正确答案是B。
