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).

[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 [br] 【S7】
选项
答案 D
解析 空前的in和空后的that从句不缺任何成分表明，本空应填动词的现在分词，[B]stressing，[D]claiming和[E]adapting入选。[E]很明显不符合语境，故排除。exaggerate和disregard提示本空应填一个贬义词，故答案为[D]claiming“声称，断言”。此处是说，他们夸大事实地断言，盈利能力是引导技术变革的关键因素.
