I found NHK started broadcasting their radio program on business English, "ビジネス英会話", online from this month. I went to a book store and bought a textbook for the program without any delay. It's really super!
Until now, I've taken TOEIC two times. In either times, the score of listening is terribly lesser than reading. I must enhance my ability of listening, but to put it into practice is difficult, so expect the program helps me to do so.
