Question

问下面这个句子有没问题!
书上有个例句,我怀疑有点问题,All the tickets had been sold out,we had to wait to for the next week's show.这是独立主格结构,我对第一个had的用法有点质疑,而且书上说这句前半句等于as all the tickets having been sold out

Answer 1

All the tickets had been sold out,we had to wait for the next week's show.这个句子中不包含独立主格结构.
像下面这个句子才包含着一个独立主格结构：
All the tickets having been sold out,we had to wait for the next week's show.
