in my opinion, vocabulary is not so important,if you know about two to three thousand words except some professional words ,you can commuciate with foreigners freely , the key point is your pronunciation , if you have a good pronunciation your cability of listening will be better either. so that's why we usually learn pronunciation for students on foreign language suject in compus.
I like English,but I feel it's not easy to learn English well. My English reading and writing is not so good not so bad.What makes me sad is my English spoken and listening. The poorest one is listening. I kept listening MP3 to improve my listening for a short time. I found I made a little progress. hehe...
Improving english isn't so easy. You must set down learning plan ,develop interests,have enough self- confidence , persistence,patience,determination and then carry out these plays to demands .Step by step ,so after two or three years ,you could take much progress in oral ,writ ing and reading english.
I am so eager to learn english.But as my patience,persistence,determination and studying way is not so good. Then i have a little further at improving oral english
