有一读者问这样一句话：
What is certain is that a seventh-century Christian church was burned down in 1807, to be succeeded by the Norman church of Old St.Paul's.
如何分析 to be succeeded?
这里的不定式短语 to be succeeded by the Norman church of Old St.Paul's 相当于 which was to be succeeded by the Norman church of Old St.Paul's，用作非限制性定语，修饰其前的 that 从句。
