are there any short-cut in improving listening comprehension

are there any short-cut in improving listening comprehension?
I have been persisting in listening to BBC for a year,
but I still find it unsurmmontable to cross the barrier.
I only can understand 65 percent of what they are talking.
this problem has harried me for a long time for I have
met the bottleneck.so could you offer some short=cut in
improving listening comprehension?period.

Hi silkrug,My name is dick and I majored in English.I`ll give some suggestions on improving your listening comprehension.First,when you are listening to some paragraphs.please,Make sure that you had enough vocabulary,and make sure that your pronunciations are correct.BBC is not good for you unless you have been learning English for a long time.Learning a Languge needs your patience,diligence,but surely,it needs some methods which fits you well.That is,Find your own way to the destination.Practsing!Before you are listening to BBC,First make sure that the article you are listening to ,can be easily read.Pay special attention to your pronunciations.Imitating the foreigners`pronunciation.Read firstly,then listening.
Your friend,dick
e.g.
If your loved one claims to “only have eyes for you” this Valentine’s Day,it might be truer than you think.Research shows that people in a committed relationship who have been thinking about their partner actually avert their eyes from attractive members of the opposite sex without even being aware they are doing it.
Psychologist Jon Maner of Florida State University and his colleagues flashed pictures of faces on a computer screen for half a second,following it immediately with a square or circle,which participants had to identify by pushing the correct button.Earlier research using this method has found that it takes longer for viewers to shift their attention away from attrac­tive faces of the opposite sex.

Maner,however,took subjects who were married or living together monoga­mously and asked half of them to write about feelings of love for their partner and the other half to write about a happy experience.Those who wrote about love actually turned their attention away from attractive members of the opposite sex even more quickly than they looked away from average-looking people.Subjects who wrote about being happy,however,remained as distracted by a pretty face as ever.
This unconscious attentional bias probably evolved to help men and women stay in monogamous relation­ships,which in humans tend to have a reproductive advantage,Maner explains:“This whole research area is guided largely by an evolutionary perspective.These biases have been built into our psychology to enhance people’s reproductive success.”
