题目解答
答案
本题考察对过去情况的虚拟语气。前半句“must have had an accident”表对过去事件的推测，后半句需用“would have + 过去分词”表与过去事实相反的假设。A项“would have been here”正确，表示“否则他当时就会在这里”。B项“would be”不符过去时间；C项“should be”无虚拟含义；D项“had just had”未体现假设关系。综合分析，A项最贴合题意。
答案：A. would have been here
解析
本题考查虚拟语气在表示与过去事实相反的假设中的用法。关键点在于：
- 前半句“must have had an accident”是对过去事件的推测，后半句需通过虚拟语气表达与该推测相反的结果；
- “or”在此处连接的是一个含蓄的条件句，相当于“if he hadn’t had an accident”；
- 虚拟语气的结构需与过去时间一致，正确形式为“would have + 过去分词”。
选项分析
A. would have been here
- 符合虚拟语气结构：“would have + 过去分词”表示与过去事实相反的假设。
- 逻辑：如果他没有出事故（与“must have had an accident”构成反义），那么“would have been here”表示“本应该出现在这里”。
B. would be here
- 错误原因：使用“would be”表示现在或将来的虚拟，但题目中“then”明确指向过去时间，需用完成时态。
C. should be here
- 错误原因：虽然“should”有推测含义，但“should be”是现在时态，无法体现与过去事实相反的虚拟关系。
D. had just had
- 错误原因：仅用过去完成时描述事实，未体现假设关系，且“had just had”与前文“must have had”重复。
