本段转折。“将会用一个案例来全面审查商业方法专利”。最后一句“它有可能排除一种专利(即上文的business-method patent)”

　　26. Business-method patents have recently aroused concern because of

　　[A] their limited value to business

　　[B] their connection with asset allocation

　　[C] the possible restriction on their granting

　　[D] the controversy over authorization

　　选[C]，根正苗红的同义替换。possible= potential ， eliminate= restriction

　　[A] 无中生有 [B] 用第一段的一个小例子中的细节捏造选项 [D] controversy 无中生有。

　　27. Which of the following is true of the Bilski case?

　　[A] Its ruling complies with the court decisions

　　[B] It involves a very big business transaction

　　[C] It has been dismissed by the Federal Circuit

　　[D] It may change the legal practices in the U.S。

　　选[D] potential= may ,change 对应着第一段和第二段之间的转折。从本段的review，eliminate也可以看出这是一种转折。

　　全文一直没有讲Bilski case的判决的结果，而 [A] [C]都是在讲其判决结果，所以与原文相反。

　　[B] 是从原文“ a “very big deal””字面意识出发设置的干扰选项。a big deal 其实在英文中的意思是“重要”，而不是“生意(transaction)”

　　本题[D]还有may ,正确答案往往语气委婉，所以更加确定选这个选项。

　　Curbs on business-method claims would be a dramatic about-face, because it was the federal circuit itself that introduced such patents with is 1998 decision in the so-called state Street Bank case, approving a patent on a way of pooling mutual-fund assets. That ruling produced an explosion in business-method patent filings, initially by emerging internet companies trying to stake out exclusive pinhts to specific types of online transactions. Later, move established companies raced to add such patents to their files, if only as a defensive move against rivals that might bent them to the punch. In 2005, IBM noted in a court filing that it had been issued more than 300 business-method patents despite the fact that it questioned the legal basis for granting them. Similarly, some Wall Street investment films armed themselves with patents for financial products, even as they took positions in court cases opposing the practice。

　　28. The word “about-face” (Line 1,Para 3) most probably means

　　[A] loss of good will

　　[B] increase of hostility

　　[C] change of attitude

　　[D] enhancement of disnity

　　本题是词汇题，一定要返回原文通过上下文解题。Because 之前是说对business-method 的约束(curbs)，而because之后说的是“正是联邦审判引入了business-method”，所以二者之间自然表明了是“态度的转变”。所以选[C]

　　The Bilski case involves a claimed patent on a method for hedging risk in the energy market.  The Federal circuit issued an unusual order stating that the case would be heard by all 12 of the court’s judges, rather than a typical panel of three and that one issue it wants to evaluate is weather it should “reconsider” its state street Bank ruling。
