问题     The promise of finding long-term technological solutions to the problem of world food shortages seems difficult to【S1】______. Many innovations (改革, 创新) that were once heavily supported have since fallen by the wayside. The proposals themselves were technically【S2】______. but they proved to be economically unavailable and culturally unacceptable to their consumers.
    One characteristic【S3】______to unsuccessful food innovations has been that, even with extensive support, they often have not been technologically adapted or culturally acceptable to the people for whom they had been developed. A successful new technology, therefore, must【S4】______the entire social-cultural system in which it is to find a place.
    The adoption of new food technologies depends on more than these technical and cultural【S5】______. economic factors and governmental policies also strongly influence the ultimate success of any innovation. Economists in the Anglo-American tradition have taken the【S6】______in investigating the economics of technological innovation. (Although they exaggerate in【S7】______that profitability is the key factor guiding technical change — they completely disregard the substantial【S8】______of culture — they are correct in【S9】______the importance of profits). Most technological innovations in agriculture can be【S10】______used only by large landowners and are only adopted if these profit-oriented business people believe that the innovation will increase their incomes.
[A] fully [F] considerations [K] common
[B] stressing [G] lead [L] largely
[C] attempt [H] average [M] visible
[D] claiming [I] fit [N] fulfill
[E] adapting [J] feasible [O] effects
【S9】
选项
答案B
解析 空前的in和空后的名词短语表明，本空应填动词的现在分词，[B]stressing和[E]adapting入选。结合语境，前面提到经济学家的观点：盈利能力是引导技术变革的关键因素，他们夸大了利益的影响，也是因为他们认为利益很重要。再结合本段第一句提到经济因素也会影响任何创新最后的成功可推断出，他们强调经济利益的重要性是正确的，故答案为[B]stressing“强调”。
