can be done at any age and any level of education.Even college students can benefit from an enlarged vocabulary，which will enhance spoken and written communication as well as providing a deeper grasp of any language.Often people are encouraged to improve their vocabulary by a major test，but improving your vocabulary can be done for fun as well.Reading more，playing word games and puzzles，and looking up words in the dictionary are all good ways to learn new words.‎ One of the best ways to improve your vocabulary is to read more.Reading is directly linked with a larger vocabulary，especially if you seek out books in unfamiliar styles or about unfamiliar topics.Nonfiction in a wide variety of fields can teach you new words and general knowledge，but reading fiction is also highly beneficial.As you read，make a note of unfamiliar words，look them up，and write down the definition.‎ Playing word games is a fun way to learn new words.Games like Scrabble and Boggle will encourage your brain to play with words and letters，as well as learning new ones.If you play with an open dictionary，you can encourage people to try out words they might otherwise be afraid of using.Most word games are interactive，so you enjoy company while you expand your vocabulary.‎ Another way of improving your vocabulary is to do word puzzles.Most newspapers include crosswords，simple cryptology puzzles，and jumbles that get progressively harder throughout the week.Try to commit to completing all of the word puzzles every day，or at least attempt to finish ‎ them.Word puzzles can also be done in groups，especially if you enjoy competition.You can purchase books of word puzzles of varying difficulty for a different challenge.‎ A simple way to improve your vocabulary is to use the dictionary.Create flashcards of unfamiliar words and practice them in the train，on the bus，or when you wake up in the morning.Try to practice words in a variety of environments so that you really learn them，and make sure to use the words in daily sentences as well so that you can grow accustomed to using them correctly.If you hear someone using a word you don’t recognize，ask him or her about it or look it up.‎ ‎1．What does the underlined word “enhance” in Paragraph 1 probably mean?‎ A．Improve.
