1. A decade ago, adapting the infrared scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. (1997. 阅读. Text 4)
【译文】十年前，通过改进用于军事目的红外线扫描技术和人造卫星，物理学家史蒂芬·帕雷提出了一种快速检测农作物温度的方法以判断哪一处的作物正遭受病虫害。
【析句】复合句。主句physicist Stephen Paley came up with a quick way to take...to determine...,主句中有两个递进的目的状语to take...和to determine...,which ones are under stress作determine的宾语从句。adapting the infrared...satellites为现在分词作方式状语从句。

【译文】其目标是使农民准确地喷洒杀虫剂，而不是在包括没有受到虫害作物的整片农田上大量喷洒农药。
【析句】复合句。主句The goal was to let...rather than...,不定式to let作表语，句中包含短语rather than，最后是which引导的非限制性定语从句,而定语从句中又包含了plants的定语从句that don't have pet problems.
