I know it’s normal for such a thing to happen, but we _____ it if we’d been more careful.
A．need have avoidedB．could have avoided
C．will have avoidedD．had avoided
B

試題分析：考查虛擬語(yǔ)氣：句意：我知道這樣的事情發(fā)生是很正常的，但是如果我們更小心點(diǎn)本來(lái)是可以避免的。根據(jù)從句if we’d been more careful.可知是和過(guò)去相反的虛擬語(yǔ)氣，主句用could have done，need have done本來(lái)需要做…而沒(méi)有做，will have done是將來(lái)完成時(shí)，had done是過(guò)去完成時(shí)，選B。
