▲《薄冰高级英语语法》第7. 74节认为：过去进行时有时可表示过去未实现的愿望或打算，此时的助动词 was / were 须重读。如：

I was coming. 我本要来的。

I was reading a paper yesterday. 我昨天本要读论文的。 (was须重读，否则会误会为真事)

Oh dear! I was writing him a letter this morning and forgot all at it. 哎呀! 我本打算今天上午给他写信来着，后来就全给忘了。

I was seeing him tomorrow. 我本来计划明天见他。

▲下面一题中的 was coming 也属于以上用法（表示过去未实现的愿望或打算）：

I ______ to visit you later that day, but I had to phone and cancel. (2013江西卷)

A. come B. came C. am coming D. was coming

句意为：那天我本来打算晚点去拜访你的，但我又不得不打电话取消了。

类似例句：

I was coming to your house last night but it rained. 我本来打算昨晚到你家来的，但下雨了。
