练习4：虚拟语气强化练习题

Part I. Multiple Choice

A. had taken, might still have been

C. might have taken; had still been

句意：如果他听了医生的建议，他现在可能还活着。

解析：这是错综时间条件句，从句说的是过去听医生的建议，主句说的是现在的情况。因此从句中用过去完成时表示对过去事情的假设，主句中用“情态助动词might+动词原形”的形式表示对现在情况的假设。

A. were; would have let

C. had been; had let

句意：如果你是健康的，昨天我就会让你去旅行了。

解析：这是针对已经发生了的事情的假设，健康状态及旅行说的都是昨天的事，因此从句中用过去完成时表示假设，主句中用would+have done的形式表示假设。

7. I lost your address, otherwise (or) I _________ you long before.

that

that从句中用动词原

to the hospital as soon as possible.

that从句中用

D. should know

解析：这是表达非现实的愿望。Wish后的that从句中，如果是针对现在的时间而言，那么动词用过去时表示非现实的愿望。

that从句中用动词原形表示主观

A. should not succeed

B. would not succeed

Part II. Error Analysis

1. Your director would have been inclined to favor your request if you would have

waited for another occasion when he was less busy with other more important matters.

修改：would have waited →had waited

句意：如果你能等到主管处理不太重要事情的、不太忙的其他时候，他是有可能愿意接受你的请求的。

解析：根据语境及句中时态判断，找主管提出请求这件事已经发生了，针对过去事情的假设，从句中应该使用过去完成时。

expects cast takes the time to

句意：重要的是，每个想要投选票的公民要花点时间公开评估这些问题。

解析：It is important that…句型中，用动词原形表达主观意愿。此处that从句中包含一个定语从句who expects to cast his vote，that从句的主语为every citizen, 谓语动词为take，只在谓语动词上使用主观意愿的虚拟语气，其他动词不涉及。
