     Listening is an important part of communication, and it is different from hearing. Being a good and

patient listener helps you not only solve many problems at work or home, but also see the world through

the eyes of others.  1  Though listening to other people may seem simple, doing it well takes efforts and

lots of practice.    

     Place yourself in the other person's shoes. You must look at the problems from the other person's

viewpoint and actively try to see his or her point of view.   2  Don't tell him that if you would have been in

his or her shoes, you would have seen your way through the problem much faster.

Give all of your attention. Turn off cell phones. It may be the easier to arrange to talk somewhere nothing will disturb you.    3  

       4   Nodding your head means you hear what the speaker is saying, and will encourage him to

continue. Body language that is similar to the speaker will allow the speaker to relax and open up more.

Do not interrupt (打断) with what you feel or think about the topic being discussed.   75   Active listening

requires the listener to put aside his or her own opinions for a while, and let another person talk the

situation out and find his or her own way.

A. In addition, you learn a lot from listening.

B. Repeat some of the words said by the speaker.

C. Wait until another person asks for your opinion.

D. Follow and encourage the speaker with body language.

E. When you look at the person you are listening to, look into his eyes.

F. It is not a good idea to consider yourself to be smarter than the speaker.

G. Quiet your mind and open yourself to whatever the person might have to say.
