Thanks to all TA's suggestions, though I could not fully understand the comments yet. Are you suggesting that I can go to the east asian library to listen to CDs? I tried to listen to the CD in other computers in computer labs, however I felt that's not sufficient. I feel a pressing need of owing an Ipod and listen to Japanese wherever I am. Well, after all, this was the way I learned English, I found it extremely useful. By subjecting myself to the environment, not only my listening ability will be significantly improved, also speaking.
I finally got myself to purchase 12 packs of notecards and put vocabs we learned in catagories, such as objects, verbs, places, identity/nationality and so on. They helped a lot. (Though the cards are expensive!!!!!)
Hope that some people can show up on Tuesday night for our practice session.
