2、Genetically Modified FoodEuropean ｕｎｉｏｎenvironmental officials have determined that two kinds of genetically modified corn could harm butterflies, affect food chains ａｎｄ　disturb life in rivers ａｎｄ　streams, ａｎｄ　they have proposed a ban on the sale of the seeds, which are made by Dupont Pioneer, Dow Agrosciences ａｎｄ　Syngenta. The preliminary decisions are circulating within the European Commission, which has the final say. Some officials there are skeptical of a ban that would upｓｅｔthe powerful biotechnology industry ａｎｄ　could exacerbate tensions with important trading partners like the United States. The seeds are not available on the European market fｏｒcultivation.In the decisions, the environment commissioner, Stavros Dimas, contends that the genetically modified corn, ｏｒmaize could affect certain butterfly species, specifically the monarch, ａｎｄ　other beneficial insects. Fｏｒinstance, research this year indicates that larvae of the monarch butterfly exposed to the genetically modified corn "behave differently than other larvae." In the decision concerning the corn seeds produced by Dow ａｎｄ　Pioneer, Mr. Dimas calls "potential damage on the environment irreversible." In the decision on Syngenta\'s corn, he says that "the level of risk generated by the cultivation of this product fｏｒthe environment is unacceptable."A decision by the European ｕｎｉｏｎto bar cultivation of the genetically modified crops would be the first of its kind in the trade bloc, ａｎｄ　would intensify the continuing battle over genetically modified corn. Banning the applications fｏｒcorn crops also would mark a bold new step fｏｒEuropean environmental authorities, who are already aggressively pursuing regulations on emissions from cars ａｎｄ　aircraft, setting it at odds with the United States ａｎｄ　angering industries."These products have been grown in the U. S. ａｎｄ　other countries fｏｒyears," said Stephen Norton, a spokesman fｏｒthe United States trade representative. "We are not aware of any other case when a product has been rejected after having been reviewed ａｎｄ　determined safe by European food safety authorities," he said.Barbara Helfferich, a spokeswoman fｏｒMr. Dimas, declined to comment on the specifics of the procedure because commissioners had not yet made a final decision. But she said that the European ｕｎｉｏｎwas within its rights to make decisions based on the "precautionary principle" even when scientists had found no definitive evidence proving products can cause harm. She said that the decisions by Mr. Dimas could go before the commission within a few weeks, but she said that no date had been set. In the decisions, Mr. Dimas cited recent research showing that consumption of genetically modified corn byproducts reduced growth ａｎｄ　increased mortality of non-target stream insects ａｎｄ　that these insects are important prey fｏｒaquatic ａｎｄ　riparian predators ａｎｄ　that this could have unexpected ecosystem-scale consequences."Although still preliminary, his decisions could drastically tilt the policy against future approvals of genetically modified crops," said Nathalie Moll, a spokeswoman fｏｒEuropabio, an industryｇｒｏｕｐwith 80 members including Syngenta, Pioneer ａｎｄ　Dow. Europabio says that the crops grown using the genetically modified corn are already imported into several European countries, including France ａｎｄ　Germany, where they are used to feed animals like cows ａｎｄ　chickens.Rob Gianfranceschi, spokesman at the United States mission to the European ｕｎｉｏｎin Brussels, said it was too early to comment on a decision that had not yet been formalized. But he made clear that the United States remained frustrated with European policies on genetically modified crops.The word "tilt" (line 1, paragraph 6) most probably means ______.【单选题】

A.incline

B.affect

C.induce

D.evoke

正确答案:A

答案解析:猜词题。根据上下文含义，尽管他的决定还是初步的，但是却会极大地倾向于针对同意未来转基因作物的政策，对比四个选项，只有incline符合此意，故正确答案为A。
