CR第1部分

【OG20-P574-651題】Farmer: Worldwide, just three grain crops-rice, wheat, and corn-account for most human caloric intake. To maintain this level of caloric intake and also keep pace with global population growth, yields per acre from each of these crops will have to increase at least 1.5 percent every year, given that the supply of cultivated land is diminishing. Therefore, the government should increase funding for research into new ways to improve yields

Which of the following is an assumption on which the farmers argument depends?

A. It is solely the governments responsibility to ensure that the amount of rice wheat, and corn produced worldwide keeps pace with global population growth

B. Increasing government funding for research into new ways to improve the yields per acre of rice, wheat, and corn crops would help to increase total worldwide annual production of food from these crops

C. Increasing the yields per acre of rice, wheat, and corn is more important than increasing the yields per acre of other crops

D. Current levels of funding for research into ways of improving grain crop yields per acre have enabled grain crop yields per acre to increase by more than 1.5 percent per year worldwide

E. In coming decades, rice, wheat, and corn will become a minor part of human caloric intake, unless there is government-funded research to increase their yields per acre

答案：

農(nóng)民：在

世界范圍內(nèi)，只有三種糧食作物-水稻、小麥和玉米-占人類卡路里攝入量的絕大部分。為了保持這一熱量攝入水平，也為了跟上全球人口的增長，鑒于耕地的供應正在減少，這些作物每英畝的產(chǎn)量每年至少要增加1.5%。因此，政府應該增加資金，研究提高產(chǎn)量的新方法。目標管理，假設型增強題。

A.探討責任問題，無關(guān)

B.增大資金頭伏確實會幫助提供產(chǎn)量，正確

C.與其他作物的比較，無關(guān)比較

D.現(xiàn)在的資金投入水平已經(jīng)增加了產(chǎn)量，與繼續(xù)增大投入能否進一步增大產(chǎn)量無關(guān)

E.如果不投資，未來這三種作物不再是卡路里攝入的主力，不是就不是，可以換別的成為主力，只要能實現(xiàn)目標就行。
