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
【S1】
选项
答案N
解析 本句可简化为The promise seems difficult to 47 。分析句子结构可知，to【S1】______在句中作状语，to为不定式小品词，故本空应填原形动词，[C]attempt，[G]lead，[H]average，[I]fit和[N]fulfill入选。根据空前的promise可确定，本空所填词应与promise形成语义场共现，只有[N]fulfill“履行，实现”合适。此处是说，针对全球粮食短缺问题，寻找长期的技术解决方案，这一承诺似乎很难实现。
