单选题 I think it's high time we ______ strict measures to stop pollution.
  • A. will take
  • B. take
  • C. took
  • D. have taken
【正确答案】 C
【答案解析】[解析] 虚拟语气 [试题精解] It is high time(that)这个句型的意思是“现在是必须……的时候了(不能再等了)”。此句型中从句的谓语要用动词的过去式，这并不代表一般过去时态，而是对现在时态的虚拟语气。如：It is high time that you made up your mind．(你该下定决心了。)
