单选题 In this country it is required that (any one) who (has) recently (come) here (has to pay) taxes.
  • A. any one
  • B. has
  • C. come
  • D. has to pay


【正确答案】 D
【答案解析】[分析] 在“it is+ required，suggested，ordered，proposed，demanded，recommended等+从句”中，从句中要用虚拟语气，构成是(should)do。改“has to pay”为“(should)have to pay”。
