问题     For many people, genetically modified foods raise all kinds of questions. Particularly in countries with long agrarian(耕地的)traditions—the idea seems against nature.
    In fact, genetically modified foods are already very much a part of our lives. A third of the corn and more than half the soybeans and cotton grown in the US last year were the products of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the US this year. The genetic genie is out of the bottle.
    Yet there are clearly some very real issues that need to be resolved. Like any new product entering the food chain, genetically modified foods must be subjected to strict testing. In wealthy countries, the debate about biotech is tempered(缓和)by the fact that we have a rich array of foods to choose from— and a supply that far exceeds our needs. In developing countries desperate to feed fast growing and underfed populations, the issue is simpler and much more urgent: Do the benefits of biotech outweigh the risk?
    Yet for all that promise, biotech is far from being the whole answer. In developing countries, lost crops are only one cause of hunger. Poverty plays the largest role. Today more than 1 billion people around the globe live on less than $ 1 a day. Making genetically modified crops available will not reduce hunger if farmers cannot afford to buy the food those farmers produce.
    Nor can biotech overcome the challenge of distributing food in developing countries. Taken as a whole, the world produces enough food to feed everyone—but much of it is simply in the wrong place. Especially in countries with underdeveloped transportation, geography restricts food available as dramatically as genetics promises to improve.
    More and more biotech research is being carried out in developing countries. But to increase the impact of genetic research on food production of those countries, there is a need for better cooperation between government agencies and private biotech firms to find and deliver biotech solutions for farmers in developing countries.
It is implied in the last sentence in Paragraph 2 that______.
选项 A、biotech in the US is still in its experimental stage
B、biotech has been applied to agriculture in the US on a large scale
C、the genetic monster has escaped from the tube in the laboratory
D、the bottle is too small to hold the genetic genie
答案B
解析 事实细节题。文章第二段提到，美国去年所生产的谷物、大豆和棉花中的很大一部分都是生物科技产品，而美国今年将种植更多的转基因农作物。这些事实说明，生物技术在农业中已被广泛使用，它像逃出瓶子的神怪一样已经来到了这个世界，故B)正确。A)与这段所述内容矛盾；本段最后一句话是一个暗喻，说明生物科技已经用于实际生活中，而不是真的有这样一个怪物，所以排除C)和D)。
