[문 12 ~ 문 13]
Chances are that you have regular access to a computer. Online dictionaries can do just about anything regular dictionaries do. Using your Web browser, type in “online dictionaries,” and you'll be presented with a wide range of choices. Some of the hardcover dictionaries that you may be familiar with maintain their own online dictionaries, too. Some companies have developed online dictionaries, which are just as good. Once you find one you like using, just add it to your list of “favorites,” and you will have easy access to it. These Web sites offer multiple resources (thesauruses, encyclopedias, and quotation guides, to name a few), and you will need to determine which are ___________ and which require some membership fee.
