题目解答
答案
前半句“He must have had an accident”表明对过去事故的推测，后半句需用“would have + 过去分词”表与过去事实相反的假设。“then”明确指向过去，故排除B、C、D。选项A“would have been here”正确表达了“否则他当时就会在这里”的含义。
答案：A. would have been here
解析
本题考查虚拟语气在含蓄条件句中的用法。关键点在于：
- 前半句"He must have had an accident"是对过去的推测，隐含"if he hadn't had an accident"的条件；
- or连接的从句表示与过去事实相反的假设，需用would have + 过去分词结构；
- 时间标志词then进一步确认需用完成时形式。
选项分析
A. would have been here
- 正确。符合虚拟语气中与过去事实相反的假设结构（would have + 过去分词），且与then的时间指向一致。
B. would be here
- 错误。would be表示与现在事实相反，但then指向过去，时态不符。
C. should be here
- 错误。should表示推测或义务，但此处需要虚拟语气，且时态不匹配。
D. had just had
- 错误。过去完成时表示已完成的动作，但此处需表达假设性结果，而非事实。
