If you were a cat, you might be an extremely clever cat that I've never seen before.:)

@ Enyo miowwwwww it's psychology that's all. You've just written a beautiful paragraph to me, almost perfect, better than a lot of English people's. My daddy doesn't think he knows 22,400 (or whatever it was) words, he knows the words he needs to use, and when he doesn't know a word's meaning, he uses the dictionary, if he wants some suggestions/synonyms, he uses a thesaurus. Which means you and my daddy are the same student, just in slightly different places in your respective development. And my daddy thinks you're incredibly clever to be able to speak Mandarin and Cantonese. You know enough English to learn any English that you want, so never put yourself down, the work you must do from here forwards, is much easier than the work you've already done to get here. Your command of tenses and verb conjugations are wonderful, they show me that you really understand the language. I speak Cat, and I type English and Spanish, but it's hard because my paws hit 2 keys at a time. Climbing trees is so much easier, and so much more fun. Miowwwww (and 5 years will pass like 5 minutes, when you get older, time gets faster, when you look back you think "where did the time go?" so knowing that, you will have a native's vocabulary in 5 years, and when you look back you wont feel the effort.)

@Mitten: I really felt frustrated because of the result. As a native speaker knows about 20000-35000, even if I keep learning 10 new words everyday, I can only get 3600 for one year. It will take about 5 years to catch up with native speakers. Not to speak of those I learned and then forgot...But I think you are right. The most important thing is to use those I've known properly. Thanks for encouragement. :)

miowwww hahahaha @Ralph, my Daddy says if you know so many words, why do you only talk utter bollocks all the time? hehehe He didn't include words like, "poo poo" and "wee wee", so gan design a building or something :D

37,800 - read it and weep my friend! (I guess there have to be some benefits to age!)
