as soon as后面的时态

英语中的时态一般分为两种：现在时态，过去时态。
在时间状语从句中，主句用一般将来时，从句用一般现在时。
as
soon
as
一……就……，引导的就是时间状语从句；
I
am
going
to
watch
TV
as
soon
as
I
finish
my
homework.
在此句中，I
am
going
to
watch
TV
就是一般将来时，I
finish
my
homework这的finish是一般现在时。用finished
肯定不对。英语中的时态讲究主从句时态一致，除非从句所陈述的为客观事实或真理。如：
The
teacher
said
the
sun
is
bigger
than
the
earth.
He
is
going
as
soon
as
he
has
had
dinner.
在此句中，he
has
had
dinner为现在完成时，同样属于现在时态。
祝你进步！

应该选c
因为前面说的是could（can的过去时），而as
soon
as后面接的时态应该与主语时态一致，所以应该选择过去时finished
提醒lz一下，做选择题最忌讳的就是使用口头语，因为选择一定是非常正规的书面语，所以一切正确选项都是建立在合理的语法基础上的

as
soon
as
规范的是接完成时，但因为finish
是瞬间动词，不能用作完成时，即不能说你一直在finish。
补充：第一句不要用finished，前后时态需一致。
