问题 Owing to its delicate design and advanced technology, Swiss Re Tower in London uses less energy than those traditional office buildings by______.
Green architectures can reduce expenditure on the maintenance by______.
选项
答案cutting long-term energy costs
解析 由题干中的green, reduce将答案定位到原文第四段第一句：Going green saves money by reducing long-term energy costs；...[精析] 题目问的是绿色建筑怎样降低了成本。题干中的reduce expenditure是对saves money的同义转述，by在句中作原因状语，后应接动词的现在分词形式，即cutting long-term energy costs。
