Question

—How dangerous it was!
—Yes，but for the passer­by’s quick action，the girl ________.

A．was drowned

B．could have been drowned

C．had drowned

D．should be drowned

Answer 1

B

解析由but for后面的內(nèi)容可知，“要不是那個(gè)路人的動(dòng)作迅速，小女孩可能已經(jīng)溺水身亡了”說(shuō)明此處是對(duì)過(guò)去事情的虛擬，而且表示“可能”的意思，所以用could have done，根據(jù)句意應(yīng)該用被動(dòng)語(yǔ)態(tài)，所以B項(xiàng)正確。
