From the desk of Mile Mosby
The final thing is a complaint I got when I was in the Zurich branch on 3rd of this month. I know it was important because the woman actually complained to me directly on the day it happened. I was in the office and she found out somehow where I was and insisted on speaking to me personally. Apparently she’d come into the Feldstrasse office to talk to Bertha Nelson--she was our Marketing Consultant there—but was treated very impolitely. So the woman, Tina Williams, found me, told me whet had happened and asked me to deal with it. Nelson had insulted her and virtually told her to take her business elsewhere.
I dealt with it because I was on the spot. I told Nelson to come and see me at 2:30 in the manager’s office. I was still waiting at 3:00. She eventually turned up and offered no apology. She seemed quite proud of being impolite to the customer and me and then fell over. I could smell alcohol and she happily t

[单项选择]The heart bypass (心脏搭桥术)has become part of our cultural life. It has come to seem like a ceremony of passage for the successful male, a red symbol of courage in midlife. Six hundred thousand bypass operations are performed a year in the United States. After a bypass, most heart patients experience significant relief from the peculiar discomfort in the chest caused by insufficient blood to the heart muscle. In some cases the surgery can dramatically extend life. American heart patients, who now number about 12 million, are enthusiastic about the surgery. Bypass is one of the most common major operations in America.
In private, however, many of my fellow workers in medicine suspect that bypass has become too popular. A recent Harvard study showed that as many as two-thirds of patients referred for bypass don’t need it or could have it postponed. In Canada and Britain, where physicians perform bypass surgery much less frequently than they do in America,heart patients fare just as wel

[单项选择]Text 4
“The Heart of the Matter,” the just-released report by the American Academy of Arts and Sciences (AAAS), deserves praise for affirming the importance of the humanities and social sciences to the prosperity and security of liberal democracy in America. Regrettably, however, the report’s failure to address the true nature of the crisis facing liberal education may cause more harm than good.
In 2010, leading congressional Democrats and Republicans sent letters to the AAAS asking that it identify actions that could be taken by "federal, state and local governments, universities, foundations, educators, individual benefactors and others" to "maintain national excellence in humanities and social scientific scholarship and education."In response, the American Academy formed the Commission on the Humanities and Social Sciences. Among the commission’s 51 members are top-tier-university presidents, scholars, lawyers, judges, and business executives, as well as prominent figures from d
