Question

If Helen             her credit card, she could have bought the dress.

A．brought

B．should bring

C．had brought

D．were to bring

Answer 1

C

解析試題分析：句意:如果海倫帶著她的信用卡，她就能買(mǎi)那件衣服了。這里是虛擬語(yǔ)氣，根據(jù)could have bought可以判斷是對(duì)過(guò)去的虛擬，從句對(duì)過(guò)去的虛擬應(yīng)該用had done，故選C。
考點(diǎn)：考查虛擬語(yǔ)氣的用法。
點(diǎn)評(píng)：本題難度適中。虛擬語(yǔ)氣是近幾年高考的熱點(diǎn)，虛擬語(yǔ)氣的情況復(fù)雜，形式多樣，需要考生牢記它們的不同的用法，再根據(jù)不同的語(yǔ)境分析句子應(yīng)該用哪種情況的虛擬。
即學(xué)即練：I was not in Beijing last June, otherwise I _________ my son’s graduation ceremony. A.would not miss      B.didn’t miss
C.would not have missed        D.had not missed
解析：C。句意：otherwise引導(dǎo)含蓄條件句，根據(jù)背景句是與過(guò)去事實(shí)相反，故用“情態(tài)動(dòng)詞+完成時(shí)”。
