In order to apply pesticide spraying precisely,we can use infrared scanning to _____ .
A.estimate the damage to the crops
B.draw color-coded map
C.measure the size of the affected area
D.locate the problem area
此题C项干扰系数较大,汉译时,C、D两项意义相近,即确定受虫害影响的范围。根据文章第一段最后一句中的target(此处作动词,意为find the target,or locate,即确定目标方位)一词可知,正确答案为D。而C项的准确意思是测出受到虫害影响的面积的大些 ,而这并不是target一词的意义所在。
