问题 Good lighting in factories leads to greater comfort, higher ______ and productivity.
选项 A、work
B、proficiency
C、craft
D、efficiency
答案D
解析 词义辨析题。work 意为“工作”；proficiency 意为“熟练，精通”，如：acquire proficiency in a foreign language(熟练地掌握一门外语)；craft 意为“工艺，手艺”；efficiency意为“效率，效能”。本句大意为：工厂内好的照明会让人更舒适，更能提高工效和生产力。
