问题 A______division of labor has contributed most to the increase of production, promoted general welfare, and raised the standard of living in industrial countries.

选项 A、complicated
B、complex
C、sophisticated
D、regular

答案B

解析 complex“复杂的",指由许多不同部分组织起来的整体,需有较多知识才能认识掌握,如:complex process“复杂的工艺”,complex mind“复杂的头脑”,complex divi—sion of labour“复杂的劳动分工”等。complicated是complex的同义词,有难懂、解决起来费事的含义,如:complicated problem(idea,thought,case,mechanism)“复杂的问题(思想、想法、案件、机器结构)”。sophisticated“老练的,世故的”;regu—lar“正式的”。
