I always have to look up countless words in a dictionary when I study. I would like to ask you a few questions:
1. For those who haven't been to any English-speaking countries but are good at English, can you tell me
a) how do you build up your vocabulary?
b) how long does it take when you first find there is only few word you don't understand in a text?
c) how much time do you spend on building up your vocabulary each day?
