     Does this situation seem familiar to you? Your English is progressing well, the grammar is now familiar,

the reading comprehension is no problem, and you are speaking quite fluently. _ 1_  

     First of all, remember that you are not alone. Listening is probably the most difficult job for almost all

learners of English as a foreign language. The most important thing is to listen as often as possible.

     __2_  The Internet is really a useful tool for English students. You can download The RealPlayer from RealMedia.com. The RealPlayer allows you to use the Internet like a radio station.

     Once you have begun to listen on a regular basis, you might still be frustrated (受阻)by limited

understanding. __3__

     Here is some of the advice I give my students:

     ●Accept the fact that you are not going to understand everything. 

     ●Stay relaxed when you do not understand, and try listening to the material for more times.

     ● Do not translate everything into your native language.

     ● ___4__ Don't concentrate on details before you have understood the main ideas.

     ● Listen to something you enjoy.

     I remember the problems I had in understanding spoken German when I first went to Germany. In the

beginning, when I didn't understand a word, I insisted on translating it in my mind. This method usually

resulted in confusion.   _5_   Firstly, translating creates a barrier between the listener and the speaker.

Secondly, most people repeat themselves constantly. By remaining calm, I noticed that even if I didn't pay much attention I could usually understand what the speaker had said.

A. But you can't follow a native English speaker at all!

B. What should you do?

C. But listening is a problem for most of the beginners!

D. However, after several weeks, I got used to the new environment in Germany.

E. So, what you need to do is to find listening resources.

F. Then, after the first six months, I discovered two extremely important facts.

G. Listen for the general idea of the conversation.
