英語運用問題...關於vocab.

I would suggest to read a novel or book of your interest, so you can learn the grammar and vocabulary simultaneously. If you just keep memorizing the sentence and vocabulary that you copied down without understanding its terminology, it's not going to work. Just learn one or two sentences a day can help you tremendously. Remember that learning English is not an overnight miracle, it takes time. So don't rush or force yourself to fill in too much information, or else it will kill your interest.
