if there had not been a hard layer of rock beneath the soil,they would have completed the job in a hours.这句话我有2处不懂.
1.if there had not been这里的had是作“有”的意思吗 had not 是否定形式“没有”的意思?如果这样的那后面为什么要加been呢?直接if there had not a hard layer of rock beneath the soil这样不就可以了吗?
2.they would have completed the job in a hours,这句话我没能理解,应该怎么划分呢?这里的have什么意思呢?是什么用法?

这是虚拟语气的用法,if 引导的句子有真实条件句和非真实条件句,非真实条件句就是虚拟语气!
1 与现在事实相反 if + 主语+过去式,主句中:主语+ would/could/might/should + V (原形)
2 与过去事实相反if + 主语+过去完成时(had +过去分词)
主句中 主语 + would/could/might/should + have + 过去分词
3 与将来事实相反 if +主语+动词过去式 / if +主语+ were to +V(原形) / if +主语+should+V(原形) 主句中 :主语+would/could/might/should + V (原形)
