3. A。从题干意思看，句子明显用虚拟语气。If可引导虚拟的条件从句，指与事

实相反或不可能实现的假设。对过去的情景表达虚拟时，条件句谓语用had +

过去分词，主句用would/ could/ should have done的形式。

2. B。此题考查情态动词表示虚拟意义的用法。I don’t think…是否定前移。意为：

我认为没有你我们本不能做成这件事的。此题关键是要根据句意知道是虚拟语

气，其基本形式是情态动词(过去式)+ have done，所以其他选项皆可排除。

1. B。考查虚拟语气中情态动词的选择。should have done是虚拟用法，表示对过

去情况的后悔或责备，D项语气太重，不符合语境。
