28. Farmers can save a considerable amount of pesticide by _______.
A) resorting to spot-spraying B) consulting infrared scanning experts
C) transforming poisoned rain D) detecting crop problems at an early stage
判断题。问农民通过何种方式可节省杀虫剂。在文章的第二段中谈到帕里远红外线扫描服务公司利用飞机上的远红外线扫描仪夜间在3000英尺的高度探测到庄稼的情况,然后可将这些情况提供给农民,农民可喷洒农药,这样只使用原来农药量的50%-70%就足够了。故答案A的信息与本文相符;而B、C、D均不正确。
29. The application of infrared scanning technology to agriculture met with some
difficulties _______.
A) the lack of official support B) its high cost C) the lack of financial D) its failure to help increase production
词汇理解题。问远红外扫描技术用于农业上时遇到的阻力,原因何在。在本文最后段中指出:1984年,帕里公司被迫关闭的原因一资金缺乏。并呼吁说:But only if Paley finds the financial backing which he failed to obtain 10years ago.其中financial backing的意思与本题C的financial support相同。所以答案C正确。
