主动的词汇 大部分的外语学生都熟悉被动词汇的这个概念， 这就是词汇你听到或者看到时就知道是什么意思。可是那些词汇不一定是学得会自己想得出来。 会自己用的词汇是主动词汇。学习者被动的词汇比主动的比较多，原因是脑子的存储方法。此外学习者能用词汇的语义环境来推断意思。虽然如此我自己经历了一个很奇怪的情况， 这就是主动可是不被动的词汇。当我说中文时，我时不时竟然用词汇我以为我不知道，更不用说会用了。我意识到自己已经用了那个词汇之前， 如果有人问我知不知道，我就一定会回答不可能。我很想知道有没有其他人已经经历过这个情况。 Most foreign language learners are familiar with the concept of passive vocabulary. This is vocabulary that you understand when you hear or read it, but you can't necessary think of yourself. Vocabulary you can use yourself is called active vocabulary. A learner's passive vocabulary is larger than their active vocabulary. However I have experienced the strange phenomenon of active but non-passive vocabulary. When I am speaking, every so often I will use lexical items that I wasn't aware that I knew, let alone could use. Before using the word, if someone had asked me if I knew that piece of vocabulary, I would have said no. I'd be very interested to know if anyone else has experienced this phenomenon.
