Effective listening is more than simply avoiding
the bad habit ofinterrupting others while they
are speaking or finishing their sentences.In some ways, the way we fail to listen is symbolic
of the way we live.We often treat communication
as it were a race.It's almost like our goal is
to have no time__55__between the conclusion of
the sentence of the person we are speaking with
and the beginning of our own.
55.A.limit B.control C.drain D.gap
这是道完形填空题，It's almost like our goal is
to have no time__55__between the conclusion of
the sentence of the person we are speaking with
and the beginning of our own.这句什么意思？为什么填gap?

gap在此有“间隔”的意思。
这句话的意思是：（我们常把交流当成好像是赛跑那样，）我们的目标几乎好像就是：跟我们讲话的那个人的话一有结论，我们就开始我们的表达，而这之间没有时间的间隔。
