INTRODUCTION
Welcome to VOCABULARY IN CONTEXT!
A well-developed vocabulary pays off in many important
ways. Better-than-average “word power” makes it easier to
understand everything you read and hear—from textbook
assignments to TV news reports or instructions on how to repair
a bicycle. And word power obviously increases your effectiveness
as a communicator. Think about it:
As far as other people are
concerned, your ideas are only as convincing as the words you
use to express them.
In other words, the vocabulary you use when
you speak or write always significantly adds to or detracts from
what you have to say.
VOCABULARY IN CONTEXT was written especially for
you
.
The program was designed to enrich your personal “word bank”
with many hundreds of high-frequency and challenging words.
There are six thematic books in the series—
Everyday Living
,
Workplace and Careers
,
Science and Technology
,
Media
and Marketplace
,
History and Geography
, and
Music, Art,
and Literature
. Each worktext presents topic-related readings
with key terms in context. Follow-up exercises provide a wide
variety of practice activities to help you unlock the meanings of
unfamiliar words. These strategies include the study of
synonyms and antonyms; grammatical word forms; word
roots, prefixes, and suffixes; connotations; and the efficient
use of a dictionary and thesaurus. Thinking skills, such as
drawing conclusions and completing analogies, are included
as reinforcement.
A word of advice: Don’t stop “thinking about words” when
you finish this program. A first-class vocabulary must be
constantly renewed! In order to earn a reputation as a first-
rate communicator, you must incorporate the new words you
learn into your everyday speech and writing.
