Learning English for my business trip to Korea (看了整篇文章後我發現主題似乎比較偏"學習英文"!)

Next month_l will have to go to Korea. It is just a business trip; however, it is new to my colleague and me. (I think it's better to say: Although it is just a business trip, it is new to my colleague and me.) We will go to Inchon (Or: We will visit Inchon). l am learning English now and get everything ready for this trip. l am also looking for some suggestions from other friendly people. (因為你用了also，如果接著"我也希望.."的句子聽起來並沒有跟前面句子相關。我建議寫"我也正在尋求其他人的建議"，這樣和前面提到的"為出差/旅遊作準備"就比較有連貫性。)

Yesterday_l saw a suggestion: Listening to English music can improve the spoken English. On my way home_l talked to my partner who majors in English about it. She said that it is not suitable for everyone/every person. Therefore she suggested me to download some ??English document?? (English "documentary films" or?) from the Internet, and then listen carefully and repeat after each individual sentence. The more you practice, the better you pronounce.

The English vocabulary and grammar are easy for me to study. Although I passed the CET-6 (College English Test) during my time at university, I have no confidence in my spoken English due to my pronunciation. Maybe I can read the words, but I am not sure that whether my pronunciation is correct.
