单选题 A ______ division of labor has contributed most to the increase of production, promoted general welfare, and raised the standard of living in industrial countries.
  • A. complicated
  • B. complex
  • C. sophisticated
  • D. regular
【正确答案】 B
【答案解析】complex“复杂的”,指由许多不同部分组成起来的整体,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”等。A complex division of labor译为“复杂的专业化分工”,B项符合题意。A项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)”。C项sophisticated“老练的,世故的”;D项regular“正式的”。
