57--61 CBDCA

　　57.主旨题.第一段提及“Supporters of the biotech industry have accused an American scientist of misconduct...genetically modified (GM) bacterium could cause serious damage if released”，即一位美国科学家认为GM细菌一旦释放即可能造成严重损害，而支持GM(pro- GM)的则认为对方发言“exaggerated and irresponsible”。第四段直接指出“The controversy began...”，由此可以推断本文主要讲述双方针对GM细菌是否会造成严重损害，各执一词。

　　58.细节推断题。根据文章第四段末“Ingham says that when she put it in soil with wheat plants，all of the plants died within a week.”以及第五段后半部分“She added that...canceled its approval for field tests...once she had told them about her research in 1999.”可推断是 Ingham自己做试验来印证她的观点。 59.细节判断题。根据第七段“The EPA has not commented on the dispute.But…Janet Anderson，director of the EPA...says‘there is no record of a review and/or clearance to field test’.”由此可以看出EPA没有field test的记录，也没有审核，消除field test的记录，意思是与该争论划清界限，表示并没有授权进行GM field test，也没有参与。

　　60.推断题。根据第十段…I think her concerns should be taken seriously.She shouldn't be harassed in this way，’says Ann Clarke...‘It's an attempt to silence the opposition.’”，Ann Clarke认为Ingham的担忧应该被慎重对待，反对她的人不应该通过起诉来骚扰她，反对者这么做是想让她对此事保持沉默。由此推断，Ann Clarke认为Ingham的观点应该被重视 (先甭管对否)，通过试验或其他方式来论证，而不是通过法律强制手段让她对此事保持沉默。

　　61.细节判断题。由第59题的详细解释可以看出EPA并不支持Ingham的观点，这一点显而易见。至于Ingham对GM细菌研究有多大贡献，Ingham的学校对此事持什么态度都没、有提及，由此排除B、C、D三项。
