问题    In 2008, Mark Lynas, an environmental activist, was unsparing in his criticism of genetically-modified (GM) food companies, calling their claims that GM crops could feed the world "outlandish" and dismissing arguments that they could better cope with the impact of climate change "a new line in emotional blackmail" .
   In his speech at the Oxford conference on January 3rd, Mr. Lynas was no less uncompromising. "We will have to feed 9.5 billion hopefully less poor people by 2050 on about the same land area as we use today, using limited fertilizer, water and pesticides. The only way of squaring this circle will be through GM."
   Tom Macmillan of the Soil Association, which promotes the practice of organic farming, dismissed Mr. Lynas’s views and said that GM crops require extra herbicides and dearer seeds while producing more resistant weeds and pests.
   Mr. Lynas’s speech spotlights a growing tension within the environmental movement over how far to embrace technologies that have environmental benefits, when they work, but which raise fears of environmental disaster if they don’t. Mr. Lynas makes the point that greens are happy to accept scientific findings when it comes to climate change, but dismiss them as biased when they attribute benefits to GM.
   Mr. Lynas’s speech also added intriguing twists to an old debate. As he pointed out, regulatory delays introduced as a result of anti-GM movements are getting longer. Many GM crops have been waiting a decade or more for approval. And this has a cost. Mr. Lynas quotes figures from Crop Life, a Brussels based agricultural-technology association, which show that it now costs $139 million to move from discovering a new crop trait to full commercialization. That means only big companies can afford to do it, says Mr. Lynas.
   Once, criticism of GM crops advanced on all fronts: these things were unnatural, an abuse of science; they would be bad for human health and so forth. The scientific fears have so far proved groundless. The main burden of complaint now seems to be that GM technology is a product of large companies which are unresponsive to public concerns. There is obviously much to be said for and against that charge. But for the moment it is worth noting two things. First, how much narrower the complaint is than the anti-GM criticism of only a few years ago. And second, as Mr. Lynas himself points out, how much critics of the technology have themselves contributed to the dominance of large firms, by raising the cost of developing GM crops so high.
   
Environmentalists hold that GM technologies_____.
选项 A、are trustworthy when they work
B、are posing a threat to environment
C、have misled scientific research
D、can bring benefits to environment
答案B
解析 态度题。第四段第二句指出，环保人士赞同“转基因技术导致气候变化”这一科学发现，却认为“转基因技术为环境带来利益”的科学发现不够客观。climate change是指不好的改变。可见环保人士认为转基因技术对环境构成了威胁。故正确答案为B项。
