  材料:新OG TEST 3
 
  部分:SECTION 2
 
  题号:7
 
  Artificial light sources are also costly aside from lowering worker productivity. They typically constitute anywhere from 25 to 50 percent of a building’s energy use.
 
  When a plant in Seattle, Washington, was redesigned for more natural light, the company was able to enjoy annual electricity cost reductions of $500,000
 
  In context, which choice best combines the underlined sentences?
 
  A) Aside from lowering worker productivity, artificial light sources are also costly, typically
 
  constituting anywhere from 25 to 50 percent of a building’s energy use.
 
  B) The cost of artificial light sources, aside from lowering worker productivity, typically
 
  constitutes anywhere from 25 to 50 percent of a building’s energy use.
 
  C) Typically constituting 25 to 50 percent of a building’s energy use, artificial light sources
 
  lower worker productivity and are costly.
 
  D) Artificial lights, which lower worker productivity and are costly, typically constitute anywhere from 25 to 50 percent of a building’s energy use.
 
  答案: A
 
  答案解析:本题依然是一道句法题。根据前后文不难看出,原句想表达的是人工光源的缺点,除了会降低员工生产力之外还很贵。
 
  A选项中使用了分词短语做状语的结构,有效合并了两个句子,使原句结构最简洁;
 
  B选项中主语被偷换为the cost of artificial light sources,改变了句意;
 
  C选项中的表达是英文中不常用的表达方式,用and连接lower worker productivity 和costly没有直接用介词短语Aside from lowering worker productivity简洁;
 
  D选项中是一个复合句,根据简洁原则,不是最优选项。
