Question

I was __him last Wednesday but he didn't come A.

I was __him last Wednesday but he didn't come
A.about to see
B.to see
C.about to have seen
D.to have seen
答案是D，，为什么不选C

Answer 1

be about to do 将要……马上……，一般用于即将到来，还未发生的事情。如：The train is about to start.火车马上就要开了。
be to表按计划或安排要做的事。
根据句意，是我本来计划要在上周三见他，但他没来。事情已发生，不属于未发生的将来，所以不用be about to.而且这个句子明显有计划好，但是出乎意料的意思。

Answer 2

你好，Be about to do 是固定搭配，故不选C

Answer 3

be about to 是固定搭配

Answer 4

was to do sth，was和to之间不加任何adj
