问题     Genetically modified(GM)foodstuffs are here to stay. That’s not to say that food produced by【C1】______agriculture will disappear,【C2】______simply that food buying patterns will polarize. It may even be that GM food will become the food of【C3】______because consumers come to appreciate the health benefits of reduced【C4】______use.
    The reason GM food will not go away is that we need a three-fold increase in food production by the year 2050 to keep【C5】______with the world’s【C6】______population growth to ten or eleven billion. It’s not【C7】______a question of more mouths to feed either.【C8】______is often forgotten is that all these extra people will take up space, reducing the overall land【C9】______for agriculture.
    It may well be that in the long term it is the developing world【C10】______benefits most from GM foods. It’s true that for the next ten years or so GM crops may be【C11】______expensive. But the lesson of personal computers is applicable here—once the technology has been developed for money-spinning crops,【C12】______maize, soy beans and cotton, it will become【C13】______for all. This doesn’t mean, unfortunately, that families will【C14】______, but severity and duration will be helped by an【C15】______ability to produce and distribute food.
    【C16】______we move into this new era of agriculture we’re embarking on a journey the world has seen any number of times with experiments before. We have been【C17】______species of wheat for several thousand years. Genetic engineers like me are not doing anything as【C18】______as making a cabbage into a cauliflower—【C19】______has been done by plant breeders in the past. We’re simply tapping into the whole gene pool,【C20】______concentrating on one species at a time."
【C6】
选项 A、coming
B、expected
C、predicted
D、thought-provoking
答案C
解析 predicted的意思是“预料的，预计的”。不能选expected，expected含有“期待的，盼望的”的意思，人们并不盼望到2050年有ten or eleven billion那么多的人口。
