"This technique can be used (17)_____ 75 percent of agricultural land in the United States", says George Oerther of Texas A&M. Ray Jackson, who recently retired from the Department of Agriculture, thinks (18)_____ infrared crop scanning could be adopted by the end of the decade. But (19)_____ Paley finds the financial backing (20)_____ he failed to obtain 10 years ago.


选项 A、transmitted
B、transferred
C、transformed
D、transported

答案C

解析 此题属于语意搭配题。transform表示"改变,使变形",根据句意,红外扫描仪记录下的数据被转换成一幅地图,显示出哪里的庄稼在发烧,故选项transformed正确。选项transmit表示"转播",选项transfer表示"转移,调动,转让",选项transport表示"运输"。
