✔ 最佳答案
use index card. Write down the word of the index card and defnition of the back. Index card is very small and can be carried in the purse. You can use traveling time (such as riding on a bus or MTR) to memorize the words and learn new vocab this way.
Also, you may also want to try to study words that have opposite meanings. For example, easy is the opposite of difficult. Then at once you can memorize 2 words of opposite meaning at the same time.
