School shootings across the country continue to discuss the story of the student who is outcast by fellow peers and decides to lash out. These reports may leave some wondering if ostracism is a legitimate cause for violence. Kip Williams believes it is. Williams, a professor of psychology at Purdue University, recently came to campus to speak about the effects of being ostracized. These effects can be distressing, but they often go unnoticed, he said. "I would have rather been beaten or bullied than be ignored," Williams said, reflecting on what some of the participants in his experiments felt after they were left out of a game of toss. "Even two minutes of invisibility is painful," he said.
Ostracism, the act of ignoring or excluding, is a phenomenon not only found in the adult world, according to Williams. Children play simple games which leave peers out without being taught to do so. Even animals use forms of ostracism, Williams said. Lions, wolves

[单项选择]Passage Four I came across an old country guidebook the other day. It listed all the tradesmen in each village, and it was impressive to see the past variety of services which were available on one’s own doorstep in the late Victorian countryside. Nowadays a traveler in rural England might conclude that the only village tradesmen still flourishing were either selling frozen food to the villagers or selling antiques to visitors. Nevertheless, this would really be a false impression. On the surface, there has been a decline of village commerce, but its power is still remarkable. Our local grocer’s shop, for example, is actually expanding in spite of the competition from supermarkets in the nearest town. Women sensibly prefer to go there and exchange the local news while doing their shopping, instead of queuing up at a supermarket. And the grocer knows well that personal service has a considerable cash value. His prices may be a bit higher than those in the town
A. Prices there are much higher
B. Customers often have to queue up.
C. Customers can order by telephone.
D. Their personal services are satisfactory.
