What would have happened _________, as far as the river bank? A Bob had walked farther B if Bob should walk farther C had Bob walked farther D if Bob walked farther 此题的答案为什么选C, 请详细分析一下，谢谢。

Answer 1

正确答案是C
其实原句也可以这样说：What
would
have
happened
if
Bob
had
walked
father,as
far
as
the
river
bank?
翻译：如果Bob走的再远点又会是什么情况呢?比方说走到河岸旁边?
这个是
虚拟语气
,因为BOB本来就没有走到河岸那去,于是说话的人就假设这样了,因为在虚拟语气中,可以把IF去掉,但是这样要把其中的
助动词
have
/had提前,于是就出现了像你问题中的这种现象了。
