[单项选择]Patents, said Thomas Jefferson, should draw "a line between the things which are worth to the public the embarrassment of an exclusive patent, and those which are not". As the value that society places on intellectual property has increased, that line has become murkier--and the cause of some embarrassment, too. Around the world, patent offices are being inundated with applications. In many cases, this represents the extraordinary inventiveness that is occurring in new fields such as the internet, genomics and nanotechnology. But another, less-acceptable reason for the flood is that patent offices have been too lax in granting patents, encouraging many firms to rush to patent as many, often dubious, ideas as possible in an effort to erect legal obstacles to competitors. The result has been a series of messy and expensive court baffles, and growing doubts about the effectiveness of patent systems as a spur to innovation, just as their importance should be getting bigger.

B. To promote innovation.
C. To reward innovators.
D. To embarrass those applying for a patent.

I jumped at the chance to talk to one of my friends on the phone, but before I got to the phone, I could tell that the boys had begun to quarrel with each other over something. I rushed out to make peace, but before I got there, Charles had begun to fight over this. Even David, the oldest boy, who won’t usually fight with anybody over anything, was involved. First, I made them stop fighting, and then I examined Mark’s eye. I decided that it wasn’t going to develop into a black eye, but I felt that they should suffer at least a little for what they had done.
