Companies had won patents for isolated DNA for decadesby 2005 some 20% of human genes were parented. But in March 2010 a judge ruled that genes were unpatentable. Executives were violently agitated. The Biotechnology Industry Organisation (BIO), a trade group, assured members that this was just a “preliminary step” in a longer battle.On July 29th they were relieved, at least temporarily. A federal appeals court overturned the prior decision, ruling that Myriad Genetics could indeed hold patents to two genes that help forecast a woman39。 gene patents suppress innovation rather than reward it。 monopolies restrict access to genetic tests such as Myriad39。s decision, big questions remain unanswered. For example, it is unclear whether the sequencing of a whole genome violates the patents of individual genes within it. The case may yet reach the Supreme Court.As the industry advances, however, other suits may have an even greater impact. Companies are unlikely to file many more patents for human DNA moleculesmost are already patented or in the public domain .firms are now studying how genes interact, looking for correlations that might be used to determine the causes of disease or predict a drug’s efficacy, panies are eager to win patents for “connecting the dots,” explains Hans Sauer, a lawyer for the BIO.Their success may be determined by a suit related to this issue, brought by the Mayo Clinic, which the Supreme Court will hear in its next term. The BIO recently held a convention which included sessions to coach lawyers on the shifting landscape for patents. Each meeting was packed.31. It can be learned from Paragraph 1 that the biotech panies would like .[A] their executives to be active[B] judges to rule out gene patenting[C] genes to be patentable[D] the BIO to issue a warning who are against gene patents believe that .[A] genetic tests are not reliable[B] only manmade products are patentable[C] patents on genes depend much on innovation[D] courts should restrict access to gene tic tests33. According to Hans Sauer, panies are eager to win patents for .[A] establishing disease correlations[B] discovering gene interactions[C] drawing pictures of genes[D] identifying human DNA34. By saying “each meeting was packed”(Line4,) the author means that .[A] the supreme court was authoritative[B] the BIO was a powerful organization[C] gene patenting was a great concern[D] lawyers were keen to attend conventions35. Generally speaking, the author’s attitude toward gene patenting is .[A] critical[B] supportive[C] scornful[D] objective參考答案31~35 CBBCDThe great recession may be over, but this era of high joblessness is probably beginning. Before it ends, it will likely change the life course and character of a generation of young adults. And ultimately, it is likely to reshape our politics, our culture, and the character of our society for years.No one tries harder than the jobless to find silver linings in this national economic disaster. Many said that unemployment, while extremely painful, had improved them in some ways。 they were more aware of the struggles of others. In limited respects, perhaps the recession will leave society better off. At the very last, it has awoken us from our national fever dream of easy riches and bigger houses, and put a necessary end to an ear of reckless personal spending.But for the most part, these benefits seem thin, uncertain, and far off. In The Moral Consequences of Economic Growth, the economic historian Benjamin Friedman argues that both inside and outside the ., lengthy periods of economic stagnation or decline have almost always left society more meanspirited and less inclusive, and have usually stopped or reversed the advance of rights and freedoms. Antiimmigrant sentiment typically increases, as does conflict between races and classes.In e inequality usually falls during a recession, but it has not shrunk in this one. Indeed, this period of economic weakness may reinforce class divides, and decrease opportunities to cross themespecially for young people. The research of Till Von Wachter, the economist at Columbia University suggests that not all people graduating into a recession see their life chances dimmed。 it is the masses beneath them that are left behind.In the Internet age, it is particularly easy to see the resentment that has always been hidden within American society. More difficult, in the moment, is discerning precisely how these lean times are affecting society’s character. In many respects, the . was more socially tolerant enter
