B．why computer criminals are often able to escape punishment
C．how computer criminals manage to get good recommendation from their former employees
D．why computer crimes can"t be eliminated
参考答案
正确答案：B
解析：主旨题。英文的特点就是开门见山。此文亦是如此。文章第一段将主旨说得很明白：商业、政府和金融机构的运作越来越多地受到计算机的控制，需要的信息只能储存在计算机的记忆库里。所以任何聪明的人都可以按照自己的需求修改这些信息，为自己带来极大的好处。最糟糕的是：许多人被查了出来，但却丝毫不受处罚就一走了之。本段第三句话引出了全文旨在说明的问题。
