37. C细节理解题。根据文章she says. “He’s my hero. He really is my hero.”可知他的妈妈内心是欣慰的故选CNowadays more and more people are talking about genetically modified foods ( GM foods). GM foods develop from genetically modified organisms (有机体), which have had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise where an organism is exposed to chemicals to create a non-specific but stable change. For many people, the high-tech production raises all kinds, of environmental, ethical(伦理的), health and safety problems. Particularly in countries with long farming traditions, the idea seems against nature.
In fact, GM foods are already very much a part of our lives. They were first put on the market in 1996. A third of the corn and more than half the cotton grown in the US last year was the product 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.
However, like any new product entering the food chain, GM foods must be subjected to careful testing. In wealthy countries, the debate about biotech is not so fierce by the fact that they have a large number of foods to choose from, and a supply that goes beyond the needs. In developing countries desperate to feed fast-growing and under fed populations, the matter is simpler and much more urgent: do the benefits of biotech outweigh the risks?
