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

答案
| B |
解析
试题分析：考查虚拟语气：句意：我知道这样的事情发生是很正常的，但是如果我们更小心点本来是可以避免的。根据从句if we’d been more careful.可知是和过去相反的虚拟语气，主句用could have done，need have done本来需要做…而没有做，will have done是将来完成时，had done是过去完成时，选B。 |
