Ask why most people are right-handed, and the answer might fall along the same lines as why fish school(鱼成群地游). Two neuroscientists suggest that social pressures drive individuals to coordinate their behaviors so that everyone in the group gets an evolutionary edge.
Approximately 85 percent of people prefer their right hand, which is controlled by the left hemisphere of the brain. One theorized benefit of locating a particular function in one hemisphere is that it frees the other to deal with different tasks. But that idea does not explain why population-wide trends for handedness exist in the first place.
Moreover, evidence gleaned in recent years has overturned the long-held belief that human handedness is a unique by-product of brain specialization attributable to language. A suite of studies has revealed brain lateralization in species from fish to primates(灵长类). Last August, for instance, scientists discovered that in the wild, chimpanzees show hand preferences.
The presence of lateralization throughout the animal kingdom suggests some benefit from it, contend neuroscientists Giorgio Vallortigara and Lesley Rogers. Also, last August, in the journal Behavioral and Brain Sciences, the two presented evidence to support their idea that social constraints force individuals toward asymmetry in the same direction. They noted, for example, that baby chickens attack more readily when a threat appears on their left.
11.Fish school suggests that______.(B)
A. it was a necessary evolutionary process
B. it has something to do with human right-handedness
C. they need to coordinate with other fish
D. their brain function is unique
解析：细节题。文章第一段介绍左右手习惯并非人类所独有，动物也呈现类似的特点，如鱼成群的游动。这是因为社会压力迫使个体调整自己的行为，这也形成了它们的进化优势。鱼成群的游动并非必要的进化过程，而是形成了进化优势，所以不能选择A。选项C和D在原文中没有提到。B项has／have something to do with意为“和…有关”。故选B。
12.Locating a particular function in one hemisphere______.(A)
A. does not explain why handedness is such an overwhelming trend
B. does not explain why 85% people are right-handed

D. enables people to think with the other hemisphere
解析：推理判断题。根据第二段第三句话“But that idea does not explain why population—widetrends for handedness exist in the first place．”可知，大脑两半球功能分配的理论并不能解释为什么大多数人有左右手习惯。前面提到85％的人习惯使用右手，它由人的大脑左半球控制，这样做是为了让另一个半球来处理不同的任务。所以B和D选项错。故选A。
13.Due to______, human handedness is not an exclusive phenomenon in animal world.(A)

Cheap long distance, the ability to spoof caller ID(来电显示)and the credit crisis are being used to facilitate a scam called vishing.
