问题 Plants will emit an increased amount of heat when they are in poor physical condition.
Farmers can save a considerable amount of pesticide by consulting infrared scanning experts.
选项 A、Right
B、Wrong
C、Not mentioned
答案B
解析 本句说“农民可以通过请教红外线扫描专家来节省大量杀虫剂”，而在文章第二段讲到Parley远红外线扫描服务公司使用飞机上的扫描仪在夜里探测庄稼情况，并将情况提供给农民，使农民可以有针对性地喷洒农药，可知这才是农民节省杀虫剂的方法，故选B。
