与将来实事相反的虚拟

— Helen, are you going to the airport to pick up Jack the day after tomorrow?

— ________ tomorrow night., I would go.

A. Were he to come back B. If he was about to come back

C. Had he come back D. If he would come back

这里的BD不选，但是这两个句子不是符合：if+主语+动词一般过去式（be动词用were）的形式吗？

前文告诉我们Jack后天回来。

现在假设Jack明天回来，就是与将来事实相反的假设。if从句通常用以下三种形式之一：

If he were to come back tomorrow,...

If he came back tomorrow,...

If he should come back tomorrow,...

所以A无疑是正确（最佳）答案：if 省略，were 倒装。

B 项的错误在于be about to do结构是不允许和时间状语连用的。

C 项的错误在于这是表示和过去事实相反的虚拟语气形式。

D 项其实并没有错，would按照表示意愿的情态动词来理解，也是讲得通的。但A项无疑是最佳答案，应该首选A。

本题，曹老师解答得非常清晰、明确，已经很到位了。

然而，Expert 还要“画蛇添足”。而且，字体大小不一，文字4种颜色，花花绿绿的样子，解答亦无章法，表述不清。反正一般人看不懂。例如：

1. were提前句首倒装虚拟语气用法

2. 对将来动作虚拟和假设

— Helen, are you going to the airport to pick up Jack the day after tomorrow?

海伦，你后天打算去机场接杰克吗？

— Were he to come back tomorrow night., I would go.

=If he were to come back tomorrow night, I would go to pick him up.

如果他明天晚上回来，我会去接他。

(省略连词if，were提前句首倒装虚拟语气用法）

对将来动作虚拟和假设，从句谓语动词形式可以是“were to+动词原形”和“一般过去式did”“should +do动词原形”主句谓语为：would do

A. Were he to come back B. If he was about to come back

C. Had he come back D. If he would come back
