冠詞是一種虛詞，沒有詞義，沒有數(shù)和格的變化，不能單獨(dú)使用，只能幫助名詞或起名詞作用的其他詞類說明其意義。冠詞分定冠詞和不定冠詞兩大類。定冠詞特指一特定名詞，不定冠詞泛指一般普通名詞。二.不定冠詞的用法不定冠詞有a和an兩種形式，a用在以輔音開頭的名詞前，an用在以元音開頭的名詞前。它的用法如下：1.表示“一個(gè)”的意思，與數(shù)詞one相同。例如：Romewasnotbuiltinaday.羅馬不是一天建成的；偉業(yè)非一日之功。2.表示一類人或事物。例如：Adogisafaithful（忠誠的）animal.

Evenawomancandoit.3.表示“每一”，相當(dāng)于per，用于某些表示時(shí)間、重量、長度等單位前。例如：Heearnstwothousandyuanamonth.Thetrainisrunningsixtymiles(英里)anhour.4.表示同樣的人或事物，相當(dāng)于thesame。例如：Birdsofafeather（羽毛）

flock(一群）together./Theyarepeopleofakind.一群同樣羽毛的鳥在一起/物以類聚，人以群分。

5.物質(zhì)名詞或抽象名詞前用a或an表示具體意義、制成品或種類。例如：Greenteaisawonderfultea.

Sheisabeauty.（美人）Pleasegivemeacoffee.6.用于人名前，表示說話者對(duì)此人不認(rèn)識(shí)，相當(dāng)于“acertain”，也可指于某名人有類似性質(zhì)的人或事物。例如：AMr.Chencametoseeyouthismorning.

HewishestobecomeaNewton.7.有些世界上獨(dú)一無二的東西，如sun,moon,sky,universe（宇宙）,world（世間，地球）,earth（地球）等，一般前面要用定冠詞，但當(dāng)他們前面有修飾語時(shí)，則要用不定冠詞。例如：Wehopewecanseeafullmoontonight.Hesatinachair,lookingatastarry布滿星星的sky.8.在作單數(shù)可數(shù)名詞定語的形容詞最高級(jí)前，如果不表示“最”，而表“非?！?，則用不定冠詞。例如：

Thatisabestdictionary.

Thisisamosttroublesome（費(fèi)事的）case（情形，情況).9.序數(shù)詞前，一般有定冠詞，但當(dāng)表示“又一個(gè)”時(shí)，則要用不定冠詞。例如：Theyhaveasecondhouse.

WhenIsatdown,afifthmanrose(動(dòng)詞,rise的過去式,“站起來”）tospeak.10.季節(jié)、月份、日期、三餐前有修飾語時(shí)，用不定冠詞。例如：Wehadawonderfullunch.Wehadaverycoldwinterlastyear.11.用在某些固定的短語中例如：onceuponatime（從前)inahurry（匆匆忙忙）

havearesthaveagoodtime

havealookallofasudden（突然地）haveacold/fever（發(fā)熱）/cough/headacheLanguagepoints1.Beijingisahugecitywithalargepopulation.Thatcausesalotofproblems,suchastoomuchtrafficandnoise.

北京是一個(gè)人口眾多的大城市。那會(huì)引起眾多問題，比如交通擁擠，噪音污染等。

(1)

populationn.人口,人數(shù)1)集體名詞,無復(fù)數(shù)形式,在句中作主語時(shí),謂語動(dòng)詞用單數(shù)形式.

目前的人口增長很快。Thepopulationtodayisgrowingveryfast.2)population之前若有分?jǐn)?shù)或百分?jǐn)?shù)修飾時(shí),用于指具體人數(shù)作主語時(shí),謂語動(dòng)詞則用復(fù)數(shù)形式.這兒大約有五分之三的人口是農(nóng)民。

Aboutthreefifthsofthepopulation

herearefarmers.3)表示某一范圍內(nèi)有多少人口時(shí),用hasapopulationof+數(shù)詞.

中國有13億人口。Chinahasapopulationof1.3billion.4)問某地有多少人口時(shí),用

Whatis/wasthepopulationof+地名?

⑴說人、動(dòng)物、樹木等有生命的東西，主要用tall不用high例如atallwoman一個(gè)高個(gè)子?jì)D女

atallhorse一個(gè)高大的馬Languagepoints⑵說一個(gè)不與地面接觸的人和物的高時(shí)，要用

high，而不用tall。

例如

Heishighupinthetree.

他高高地爬在樹上。

Theplaneissohighinthesky.

飛機(jī)在空中這么高。⑶指建筑物、山時(shí)要tall或high都可以，不過

high的程度比tall高。⑷high可作副詞，tall不能。⑸tall的反義詞為short,high的反義詞為low。e.g.Ourfactoryisabig/largeone.

我們的工廠很大。（1）在表示物體重量、人的身高大或長大了時(shí)，只能用big。

e.g.Theboxistoobigtocarry.

這個(gè)盒子太大，拿不了。（2）在表示數(shù)量時(shí)，用large,不用big。

e.g.Alargenumberofpeoplecamefromallpartsofthecountrytoseetheexhibition.

從全國各地來了很多人觀看展覽。big和large都可表示具體事物形體或面積的大小,往往可以互換但big較口語化。e.g.TherehavebeenmanygreatpresidentsinAmericanhistory.美國歷史上有很多偉大的總統(tǒng)。在表示抽象意思時(shí),有也可用big,但great更為正式。e.g.Great/Bigchangeshavetakenplaceinour
