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”。
