一道高考英语单项Mary went to the box office at lunch time,but all the tickets ______ out.
Mary went to the box office at lunch time,but all the tickets ______ out.
A.would sell
B.had sold
C.have sold
D.was selling
B选项不是had been sold的是因为该词组物作主语时必须这么用,主动表被动意思,若改为had been sold就错误如：
This fabric washes well.这种织物很耐洗 （织物被洗）
还是因为物作主语时必须这么用,主动表被动意思,若改为had been sold也可以,如：
Your hair wants cutting.你的头发需要剪一下.（头发被修剪）
改为 Your hair wants to be cut.也是对的
还是因为两者都可行,had sold 是由于方言的原因俚语化的说法
