单选题 Some companies have introduced flexible working time with less emphasis on pressure ______
A. than more on efficiency B. than efficiency
C. and more on efficiency D. and more than efficiency

【正确答案】 C

【答案解析】[解析] 在本题中，less emphasis on pressure和more emphasis on efficiency是两个并列成分，作with的宾语。只是在后者中省略了emphasis on。选项A、B和D均无法与less emphasis on pressure一起作with的宾语，故均可排除。
