It sounds like you're starting to share a story about an experience with Jenny visiting your place. To help continue or respond to what you've shared so far, could you provide any more details about what happened when Jenny came over? I'd be happy to discuss it further or offer any advice or reflections if you'd like.

When Jenny came to my place, I_____ breakfast with James.
A have
B had
C have had
D was having

D

解析

当詹妮来我家的时候，我正在和詹姆斯吃早饭。 [考点] 动词时态 【精析】D 本句包含了一个when引导的时间状语从句，从句为一般过去时。主句中的动词have为延续性动词，此处表示过去正在进行的动作，所以主句应用过去进行时，即“was/were+现在分词”的形式。故选D。
