1．【答案】C

【解析】otherwise”否则”，连接副词，引导一个与过去事实相反的假设，相当于if I had not been held up by the traffic jam，因此句子谓语需用虚拟过去时。would be是虚拟现在时的结果句。ought tO have been”本来应该”；must have been”一定已经”，纯属推断。

2．【答案】A

【解析】lest引导的从句谓语一般多用虚拟语气should+动词原形，也可单独用动词原形，如：I’ll be kind to her lest she decide to leave me．

3．【答案】A

【解析】本题为虚拟过去时或叫非真实条件句过去时，条件句用过去完成时，作出与过去事实相反的假设，主句谓语用would／could／might have+动词的过去分词。

4．【答案】B

【解析】以only引导的状语放在句首时，句子需用部分倒装句序，即将be动词或助动词放在主语前面。

5．【答案】B

【解析】”她昨天不可能见到你，因为她根本就不在那里”。could not后面跟不定式完成式用于推断过去不可能发生某事。
