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. [br] What is the main idea of the passage?
选项 A、Problems caused by genetically modified food.
B、If the genetically modified food can feed the world.
C、If the developing countries welcome genetically modified food.
D、The largest producer of the genetically modified food in the world.
答案 B
解析 主旨大意题。文章叙述了人们利用转基因食物的现状和问题，以及转基因食物是否能真正解决世界人口的饥饿问题，故选B)。A)只是文章内容的一个方面，在第三段有所论及，但并不是文章的主旨，故排除；C)也只是论及转基因食物与发展中国家时谈到的一个方面，故排除；文章并未提及最大的转基因食品生产国，故排除D)。
