然而，这种情况随着电气设备的发展发生了改变。电气设备由启动系统、点火系统、信号系统、照明系统、仪表及报警系统、辅助电器系统和汽车控制系统组成。在这篇文章中我们非常简洁的描述了汽车电器设备，你应该学习更多的电器设备的知识。ReadingandWriting04NotesNotes1.electricaladj.有关电的VS.electronicadj.电子的electrical描述“与电有关的，电气科学的”所指范围更大；electronic描述“电子的，电路元件”其含义范围更小，针对性更强。2.Isuggestthat...我建议...Iadmitthat...我承认...文中出现的这两个句子都是典型的宾语从句；宾语从句是名词性从句的一种。在主从复合句中充当宾语，位于及物动词介词或复合谓语之后的从句称为宾语从句。NotesNotes3.dependon取决于，依赖于；在上世纪50年代以前，汽车工业的发展，极大依赖于机械科技技术的发展。随着电子技术的发展，电气设备在汽车科技中不断被运用，逐渐地，机械科技技术对汽车工业发展的制约越来越小。Notes05Word
