　　3. The robots used in nuclear pants handle the radioactive materials, preventing human personnel from being exposed to radiation. (p3)

　　翻译：核电站里使用机器人处理辐射材料，避免人员接触放射性物质。

　　分析：主语：The robots;谓语：handle;宾语：the radioactive materials;used in nuclear pants handle the radioactive materials是过去分词短语做定语;preventing human personnel from being exposed to radiation是现在分词短语做伴随状语。being exposed to动名词被动语态;prevent sb from doing 阻止某人做某事。

　　4. Robots differ form automatic machines in that after completion of one specific task, they can be reprogrammed by a computer to do another one. (p4)

　　翻译：机器人与自动化装置的区别在于它们完成一项特定任务后可以由计算机重新编程去执行另一项任务。

　　分析：该句重要考点：in that,相当于because, 所引导从句表原因。如：

　　Men are different from other animals in that the former can create and use tools while the latter cannot.
