W: Excuse me, Professor. I have a question. I’m worried about my English skills. I get good marks on tests, but I don’t feel that I’ve learnt a lot.
M: Well, it’s a good concern. But don’t worry.(22)Many advanced English learners have a large "passive vocabulary," but they worry about their "active vocabulary."(23)They can understand many difficult English words when reading or listening, but they don’t use most of them when speaking or writing in English. They feel this is a problem. They would like to use all the difficult words that they know.
W: You mean I use too few words?
M: That’s not what I’m saying at all. Actually, I’m saying the opposite thing.
W: I’m afraid I can’t follow you.
M: In your native language, there are also thousands of words that you understand but you don’t use.(24)So your active vocabulary in your native language is much smaller than your passive vocabulary. And I guess that you are not worried about that.
W: No, I’m not. But I would like to use the new words that I learn in my English classes. How else am I going to remember them?
M: Well, that’s a very good question.
W: I was hoping that you had an answer to this question.
M: (25)You don’t need to worry about using "too few" English words. As your needs for different things grow, you will be able to use your new words more and more. I think you’d be surprised by how much you know.
W: OK, I hope so.
