Which vocabulary book is difficult for me to use based on English?

I don't recommend looking for an alphabetical vocabulary book, that is, a vocabulary book arranged like ABCDEFG. That will keep you in A, and it will be annoying to carry it on your back. I suggest you find a suitable classification vocabulary, such as scene classification, synonym classification and so on. This can be found in the bookstore. This vocabulary book is convenient for your brain storm, that is, associative memory, which is faster and more effective than memorizing. There is also a software that can recite words easily. Although it is sorted in alphabetical order, it will help you improve your interest in memorizing words. In fact, memorizing words through word books is very boring. I suggest you read your favorite English story books, magazines or English movies. Memorizing words through context is more effective. That's it ~ Come on ~
