If it's really important to remember the words (like for a test), then I would make flashcards.

Practice, practice, practice. Devote some time each day to reading in English, and your vocabulary will start to expand. Practicing words you already know will help you improve your sentence structure and confidence with the language as well. You don't have to learn everything at once, just make sure you commit the time to learning and practicing. :)

我单词量还可以，至少看懂原版小说和各种英文杂志问题不大，前期发点时间背诵下单词书，有个五六千单词就多用英语，多看英文文章，单词量一下子就上来了。其实如果你不准备考试的话，单词量不是特别重要的事情，最重要的还是灵活应用吧
