It is usedas either a primary or secondary language in many countries.During the 1500s, fewer than 2 million people spoke English. All of

5、 them lived inwhat is now Great Britain. Through the centuries, as the result of various historicalevents, English spread throughout the world. Today, about 400 million people speakEnglish as their native language. Most of them live in Australia, Canada, GreatBritain, Ireland, New Zealand, South Afr

6、ica, and the United States.Another 100 million people living chiefly in Bangladesh, India, Pakistan, and inmany African countries speak English in addition to their own language. Anadditional 200 million people probably know at least some English. (From the 1998World Book Multimedia Encyclopedia)Cha

7、racteristics of EnglishVocabulary. English has a larger vocabulary than any other language. There aremore than 600,000 words in the largest dictionaries of the English language.Some English words have been passed on from generation to generation as farback as scholars can trace. These words, such as

8、 woman, man, sun, hand, love, go,and eat, express basic ideas and feelings. Later, many words were borrowed fromother languages, including Arabic, French, German, Greek, Italian, Latin, Russian,and Spanish. For example, algebra is from Arabic, fashion from French, piano fromItalian, and canyon from

9、Spanish.A number of words, such as doghouse and splashdown, were formed bycombining other words. New words were also created by blending words. Forexample, motor and hotel were blended into motel. Words can be shortened to formnew words, as was done with history to form story. Words called acronyms

10、areformed by using the first letter or letters of several words. The word radar is anacronym for radio detection and ranging.Pronunciation and spelling in English sometimes seem illogical or inconsistent.Many words are spelled similarly though pronounced differently. Examples includecough, though, a

11、nd through. Other words, such as blue, crew, to, too, and shoe, havesimilar pronunciations but are spelled differently. Many of these variations showchanges that occurred during the development of English. The spelling of somewords remained the same through the centuries, though their pronunciation

12、changed.Grammar is the set of principles used to create sentences. These principlesdefine the elements used to assemble sentences and the relationships between theelements. The elements include parts of speech and inflections.Parts of speech are the word categories of the English language. Scholars

13、do notall agree on how to describe the parts of speech. The traditional description listseight classes: nouns, pronouns, verbs, adjectives, adverbs, prepositions, conjunctions,and interjections. The most important relationships of the parts of speech includesubject and verb, verb and predicate, and

14、modifier and the word modified.English has fewer inflections than most other European languages. An English nounhas only two inflections, the plural and the possessive. Inflections are used tochange the tense and number of a verb or the case of a pronoun. Inflections can 页眉内容change adjectives to the

15、 comparative or the superlative for example, big, bigger,biggest.American EnglishAmerican English is a variety of the English language spoken in the United States.Although all Americans do not speak the same way, their speech has enough incommon that American English can be recognized as a variety o

16、f English distinctfrom British English, Australian English, and other national varieties. AmericanEnglish has grown up with the country. It began to diverge from British Englishduring its colonial beginnings and acquired regional differences and ethnic flavorduring the settlement of the continent.To

17、day it influences other languages and other varieties of English because it is themedium by which the attractions of American culture its literature, motion pictures,and television programs are transmitted to the world.Characteristics of American EnglishA. PronunciationIn broad terms, Canadian and A

18、merican speakers tend to sound like one another.They also tend to sound different from a large group of English speakers who soundmore British, such as those in Australia, New Zealand, and South Africa. For example,most Canadians and Americans pronounce an r sound after the vowel in words likebarn,

19、car, and farther, while speakers from the British English group do not. Also,some British English speakers drop h sounds at the beginning of words, so that he andhis are pronounced as if they were spelled ee and is. The English spoken in Australia,New Zealand, and South Africa sounds more like Briti

20、sh English than AmericanEnglish does because these varieties have had less time to diverge from BritishEnglish. The process of separate development began later in these countries than inNorth America.In some cases there are differences between American English and BritishEnglish in the rhythm of wor

21、ds. British speakers seem to leave out a syllable in wordslike secretary, as if it were spelled secretry, while Americans keep all the syllables.The opposite is true of other words, such as specialty, which Americans pronouncewith three syllables (spe-cial-ty) while British speakers pronounce it wit

22、h fivesyllables (spe-ci-al-i-ty). Vowels and consonants may also have differentpronunciations. British speakers pronounce zebra to rhyme with Debra, whileAmerican speakers make zebra rhyme with Libra. Canadian and British speakerspronounce the word schedule as if it began with an sh sound, while Ame

23、ricanspronounce it as if it began with an sk sound.B. WordsThe most frequently used words are shared by speakers of different varieties ofEnglish. These words include the most common nouns, the most common verbs, andmost function words (such as pronouns, articles, and prepositions). The differentvar

24、ieties of English do, however, use different words for many words that are slightlyless common for example, British crisps for American potato chips, Australianbillabong for American pond, and Canadian chesterfield for American sofa. It is evenmore common for the same word to exist with different me

25、anings in different varieties 页眉内容of English. Corn is a general term in Britain, for which Americans use grain, whilecorn in American English is a specific kind of grain. The word pond in British Englishusually refers to an artificial body of water, whereas ponds also occur naturally inNorth America

26、. British English chemist is the same as American English drugstore,and in Canada people go to the druggist. Many of the words most easily recognized asAmerican in origin are associated with aspects of American popular culture, such asgangster or cowboy.C. SpellingAmerican English spelling differs f

27、rom British English spelling largely becauseof one man, American lexicographer Noah Webster. In addition to his well-known AnAmerican Dictionary of the English Language (1828), Webster published TheAmerican Spelling Book (1783, with many subsequent editions), which became oneof the most widely used

28、schoolbooks in American history. Websters books sought tostandardize spelling in the United States by promoting the use of an Americanlanguage that intentionally differed from British English. The development of aspecifically American variety of English mirrored the newcountrys separate politicaldev

29、elopment. Websters most successful changes were spellings with or instead of our(honor, labor for the British honour, labour); with er instead of re (center, theater forthe British centre, theatre); with an s instead of a c (defense, license for the Britishdefence, licence); with a final ck instead

30、of que (check, mask for the British cheque,masque); and without a final k (traffic, public, now also used in British English, forthe older traffick, publick). Later spelling reform created a few other differences, suchas program for British programme. Canadian spelling varies between the British and
