Question

If I        you, I’d keep quiet and listen carefully in class.
A. am                       B. will be                  C. were

Answer 1

C

試題分析： 與現(xiàn)在事實(shí)相反：條件從句用動(dòng)詞過去式，主句用would/could/should/might+動(dòng)詞原形；與過去事實(shí)相反：條件從句用had done，主句用would/could/should/might+have done；與將來事實(shí)相反：條件從句用動(dòng)詞過去式/should+動(dòng)詞原形/were to do，主句用would/could/should/might+動(dòng)詞原形。句意：如果我是你，我上課就會保持安靜，認(rèn)真聽課。故選C。
