有读者问这样一道选择题：
(1)We walked as fast as we could _____.
A. to hope to catch the 9:30 train
B. hoping to catch the 9:30 train
C. to hope catching the 9:30 train
D. hoping catching the 9:30 train
有人说应选A， to hope to...是目的状语，但我认为应选B， 作为伴随状语，望赐教。
我们也会选B，因为在这种情况下，用“作伴随状语的现在分词短语 hoping+不定式”结构较为常见，但其前最好有一逗号。再如：
(2)I sat down, hoping to remain unnoticed.
这种现在分词亦可后接介词 for，如：
(3)He paused, hoping for evidence of interest.
