(4) ________ in the queue for half an hour，the old man suddenly

realized he had left the cheque in the car．

A．Waiting B．To wait

C．Having waited D．To have waited

解析：根据the old man与wait之 间的关系，应该选择v.ing形式，再根据句意得知是在主句谓语动词"realize"前就等(wait)了半个小时了，有明显的先 后关系，故要用v.ing的完成式。 答案：C

辑上的主谓关系，称之为独立主格结构。它在句中也作状语。

It being a holiday，all the shops were shut．

Class being over，children could play football．

3．有少数现在分词并不表示主语的动作，即不存在其逻辑

主语必须和句子主语一致的问题，只是表示说话人的态度。常

这样用的有：generally／frankly／properly．．．speaking

一般／坦白／恰当......说来

judging from／by...从......判断

considering...考虑到...... supposing...假设(使)......

"独立主格结构前加上with，就构成了复合结构。
