问题 -- Why haven’ t you asked her to come here? -- She ______ an important experiment when I found her and she ______ it.

选项 A、had done, didn’ t finish
B、was doing, hash’ t finished
C、did, wouldn’ t finish
D、would do, hasn’ t finished

答案B

解析本句意为：——你为什么没叫她到这里来啊?——我找到她的时候她正在做一个重要实验，到现在还没做完。后面是用when引导的时间状语，故前面需要用过去进行时态。and后面的句子是表示其对现在的影响，需用现在完成时态。
