【典型例题】
_____ to do the work, I should do it some other day.
A. If were I
B. I were
C. Were I
D. Was I
答案C. 在虚拟条件状语中如果有were, should, had这三个词,通常将if省略,主语提前, 变成 were, should, had +主语的形式。但要注意,在虚拟条件状语从句中,省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说Were I not to do, 而不能说 Weren't I to do.
e.g. Had you been here just now, you would have met her. 你要是刚才在这儿,就见到她了。
Were I not busy, I would have come. 假如我不忙,我就会来了。
十二、其他句型
1. 虚拟语气用在It is +形容词+that的主语从句中
在某些表示愿望、建议、请求、命令等形容词后的主语从句中,需用虚拟语气。其表达形式为should +动词原形或省略should直接用动词原形。这类形容词有 advisable(合理的),appropriate(适当的),compulsory(必须的),crucial(紧急的),desirable(理想的),essential(必要的),imperative(迫切的),important(重要的),incredible(惊人的),natural(自然的),necessary(必要的),possible(可能的),preferable(更好的), probable(可能的),strange(奇怪的),urgent(紧迫的), vital(极为重要的)。
