题目

why is BBC so difficult to understand?
if you don't have background of what
BBC talks,you must find it very
difficult to understand.
with the greatese effort,I only can understand
50 percent of them,I think I just hit the
bottleneck and can't improve my listening
ability further more.can you tell me how
to overcome this phase?
I don't think my vocabulary is limited,
it's also not the matter of my pronoun-
ciation.I think it's the way of British
thinking and expression which is
different from us.

答案

just like you said:I think it's the way of British
thinking and expression which is
different from us .
