      What are the best ways to learn new words? Once you have learned new words, how can you remember

them?

         1   .What is your reason for wanting to improve your vocabulary-for a purpose, like the SAT, or for fun

and general self-improvement?    2    For example, there are books specifically written with methods for

that they are useful and worth remembering, and also when they have been fully explained.    4   Most

word-of-the-day offerings supply the definition as well as an example sentence or two.

     Studies have shown that a new word will stay in your vocabulary if it is regularly reinforced (强化) through

use and reading.    5   It is great to have a quiz book with you when you have to wait in places like a dentist's

office．Keeping a quiz book in the car and on the bedside table is good, too.
