He ___________busy yesterday, or he __________you with your experiment.
A．was; had helpedB．was; would have helped
C．had been; would have helpedD．were; would have helped
B

試題分析：考查時(shí)態(tài)和虛擬語氣：句意：昨天他很忙，否則，他就可以幫助你做實(shí)驗(yàn)了。第一空是過去的事實(shí)，用一般過去式，這里or相當(dāng)于if he hadn’t been busy這樣的虛擬語氣條件句，所以后面的主句用would have helped。選B。
