单选题 An iron and steel works, with several satellite factories, ______ in that city now.
  • A) is built
  • B) is being built
  • C) were built
  • D) are being built


【正确答案】 B
【答案解析】[答案精解] 句意：那座城市正在修建一座钢铁厂和几家卫星厂。该题考查的是主谓一致。主语是an iron and steel works，后面的with several satellite factories只是补充成分，所以谓语用单数。
