Ⅲ 课文精讲
第一部分： Paras.1-3
Robots， becoming increasinglyprevalent in factories and industrial plants throughout the developed world， are programmed and engineered to perform industrial tasks without human intervention.
Para.1
1.第一句中“ becoming increasingly prevalent in factories and industrial plants throughout the developed world” 是现在分词短语作伴随状语，插在主语和谓语中间（也可放在句首）。
2.Most of today‘s robots are employed in the automotive industry， where they are programmed to take over such jobs as welding and spray painting automobile and truck bodies.
take over： 接管
lorry： 卡车
where 引导非限制性定语从句，对主句起补充说明作用。翻译时，按照原文语序即可。“目前大多数机器人用于汽车工业，它们按编程去承担轿车和卡车车身的焊接和喷漆这样的工作。”
3.They also load and unload hot， heavy metal forms used in machines casting automobile and truck frames.
此句中， “casting automobile and truck frames” 是现在分词词组作定语修饰machines， 意思是：“铸造轿车和卡车框架的机械”；而 “used in machines casting automobile and truck frames” 又是 “ metal forms” 的定语，因此本句的意思是：“机器人还可用来装卸铸造轿车和卡车框架的机械上使用的炽热、笨重的金属铸模（构件）。”
