题目内容
He ___________busy yesterday, or he __________you with your experiment.
| A．was; had helped | B．was; would have helped |
| C．had been; would have helped | D．were; would have helped |
B
解析试题分析：考查时态和虚拟语气：句意：昨天他很忙，否则，他就可以帮助你做实验了。第一空是过去的事实，用一般过去式，这里or相当于if he hadn’t been busy这样的虚拟语气条件句，所以后面的主句用would have helped。选B。
