问题 Text 2 Over the past decade,thousands of patents have been granted for what are called business methods.Amazon.com received one for its"one-click"online payment system.Merrill Lynch got legal protection for an asset allocation strategy.One inventor patented a technique for lifting a box.Now the nation's top patent court appears completely ready to scale back on business-method patents,which have been controversial ever since they were first authorized 10 years ago.In a move that has intellectual-property lawyers abuzz the U.S.court of Appeals for the federal circuit said it would use a particular case to conduct a broad review of business-method patents.In re Bilski,as the case is known,is"a very big deal",says DennisD.Crouch of the University of Missouri School of law.It"has the potential to eliminate an entire class of patents."Curbs on business-method claims would be a dramatic about-face,because it was the federal circuit itself that introduced such patents with its 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 rights to specific types of online transactions.Later,more established companies raced to add such patents to their files,if only as a defensive move against rivals that might beat 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.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 whether it should"reconsider"its state street Bank ruling.The Federal Circuit's action comes in the wake of a series of recent decisions by the supreme Court that has narrowed the scope of protections for patent holders.Last April,for example the justices signaled that too many patents were being upheld for"inventions"that are obvious.The judges on the Federal circuit are"reacting to the anti-patent trend at the Supreme Court",says HaroldC.Wegner,a patent attorney and professor at George Washington University Law School.28.The word"about-face"（Line 1,Para 3）most probably meansA.loss of good willB.increase of hostilityC.change of attitudeD.enhancement of dignity
选项 A.loss of good will
B.increase of hostility
C.change of attitude
D.enhancement of dignity
答案 C
解析 解答本题的关键是依据短语所在句意与前后句意衔接的逻辑关系来推知该短语的意思。三段首句起到了承上启下的作用，二段主要讲对营业方法专利权开始进行限制，三段首句继续讲这一限制带来的影响，三段首句是一个原因状语从句，依据because后的句意“因为联邦巡回法院在1998年推出了这项专利”，而上面讲到现在对该专利又开始进行限制，由此可知，这正是种态度的改变，故C项符合文意为正确答案。而将A，B，D代入原文，均无法与上下文的语境衔接。
