初中英語(yǔ)聽(tīng)力技巧之?dāng)?shù)字

字號(hào):


    今天小編為大家精心整理了一篇有關(guān)初中英語(yǔ)聽(tīng)力技巧之?dāng)?shù)字的相關(guān)內(nèi)容,以供大家閱讀
    ▌基數(shù)詞的讀法
    202讀作:twohundred(and)two
    234讀作:twohundred(and)thirtyfour
    1,234讀作:onethousand,twohundred(and)thirtyfour
    但是在讀法上須注意以下幾點(diǎn):
    在英式英語(yǔ)中,一個(gè)數(shù)的最后兩位(十位和個(gè)位)得用"and'',但美式英語(yǔ)中則不用。如:
    3,077U.S:threethousand,seventy-seven.
    不定冠詞"a"只在數(shù)的開(kāi)頭才和hundred,thousand等連用。試比較:
    146讀作:ahundred(and)forty-six
    2,146讀作:twothousand,onehundred(and)forty-six
    1,000這個(gè)整數(shù)我們說(shuō)athousand,在and前我們也說(shuō)athousand,但是在一個(gè)有百位數(shù)的數(shù)目前就得說(shuō)onethousand試比較:
    1,031讀作:athousand,(and)thirty-one
    1,150讀作:onethousand,onehundred(and)fifty
    hundred,thousand和million這幾個(gè)詞的單數(shù)可以和"a"者"one"連用,但是不能單獨(dú)使用。在非正式文體中"a"比較常見(jiàn);當(dāng)我們說(shuō)話(huà)比較準(zhǔn)確的時(shí)候就用"one"試比較:
    IWanttoliveforahundredyears.Thejourneytookexactlyonehundreddays.
    我們常常說(shuō)elevenhundred(1,100),twelvehundred(1,200)等,而不說(shuō)onethousandonehundred.從1,100到1,900之間的整數(shù),這種說(shuō)法最常見(jiàn)。
    11,234讀作:eleventhousandtwohundred(and),thirty-four
    155,721讀作:onehundred(and)fifly-fivethousandsevenhundred(and)twenty-one
    6,155,702讀作:sixmilliononehundred(and)fifly-fivethousandsevenhundredandtwo
    26,000,008讀作:twenty-sixmillionandeight
    326,414,718讀作:threehundred(and)twenty-sixmillion,fourhundred(and)fourteenthousand,sevenhundred(and)eighteen
    4,302,000,000讀作:fourbillionthreehundred(and)twomillion
    由以上一組數(shù)字可以看出,多位數(shù)由右向左每3位有一逗號(hào),這個(gè)逗號(hào)的作用非同小可,在記憶數(shù)字時(shí),它可以幫我們很大的忙!
    逆向第一個(gè)逗號(hào)讀thousand;向左再推三位,第二個(gè)逗號(hào)讀million;第三個(gè)逗號(hào)讀billion;第四個(gè)逗號(hào)就是trillion。這幾個(gè)逗號(hào)的作用在于,當(dāng)我們聽(tīng)到若干thousand時(shí),立即寫(xiě)下這個(gè)數(shù),并在其后打一個(gè)逗號(hào),并留出3位;當(dāng)聽(tīng)到若干million,則寫(xiě)下數(shù)字,并在其后打一逗號(hào),留出6位;聽(tīng)到若干billion,方法同上,在后面留出9位,后面的million、thousand依此法類(lèi)推,讓所有數(shù)字各就其位。
    例如,當(dāng)你聽(tīng)到"twentythousandandfour"寫(xiě)出20,"andfour"意為后一組僅有個(gè)位,即:004,那么,這個(gè)數(shù)字完整地寫(xiě)下來(lái)就是20,004;若聽(tīng)到"sixmilliontwentythousandfourhundredandtwenty-three,"則第一步先寫(xiě):6,020,再將最后一組423寫(xiě)在第一個(gè)逗號(hào)后面。完整的翠字為6,020,423。由此可見(jiàn)這個(gè)三位一逗號(hào)的作用有多大。只要我們?cè)谄綍r(shí)的訓(xùn)練中加強(qiáng)對(duì)三位數(shù)讀寫(xiě)的訓(xùn)練,就能區(qū)分"ty"與"teen'',并能借助這個(gè)不可缺少的"逗號(hào)",無(wú)論數(shù)字多么大,也不會(huì)對(duì)我們?cè)斐烧系K。
    ▌序數(shù)詞的讀法
    lst讀作:(the)first2nd讀作:(the)second3nd讀作:(the)third4th讀作:(the)fourth20th讀作:(the)twentieth21st讀作:(the)twenty-first22nd讀作:(the)twenty-second23rd讀作:(the)twenty-third其它以此類(lèi)推。
    ▌小數(shù)含小數(shù)點(diǎn)的數(shù)字,小數(shù)點(diǎn)"."讀"point",小數(shù)點(diǎn)后的數(shù)若是兩位以上,則分別讀出。
    0.5讀作:zeropointfive0.25讀作:zeroppointtwofive0.125讀作;zeropointonetwofive93,64m讀作:ninety-threepointsixfourmeters2'15.11''讀作:twominutesfifteenpointoneoneseconds
    ▌年代及日期的讀法數(shù)字表示的年份通常分成兩半來(lái)說(shuō):
    2000B.C.讀作:twothousandBC1558讀作:fifteenfifty-eight1603讀作:sixteen(hundredand)three/sixteenohthree921讀作:ninetwenty-one
    日期的表達(dá)英式和美式有所不同,請(qǐng)注意區(qū)別:英式先寫(xiě)日子,美式先寫(xiě)月份
    英:1999年4月6日=6thAprill999美:1999年4月6日=April6,1999在讀法上,英國(guó)人有兩種表達(dá)方式:
    Aprilthesixth,nineteenninety-nineThesixthofApril,nineteenninety-nine
    美國(guó)人則一般這樣表示:
    Aprilsixth,nineteenninety-nine(省略"the")
    ▌鐘點(diǎn)的讀法鐘點(diǎn)的讀法分英式和美式兩種,我們應(yīng)對(duì)此加以注意。英:
    7:00seveno'clocka.m./p.m.8:15aquarterpasteight/eightfifteen9:30halfpastnine/ninethirty9:45aquartertoten/nineforty-five10:03three(minutes)pastten/tenohthree美用法基本相似,只是英國(guó)用past之處,美國(guó)通常用after;英國(guó)用to之處,美國(guó)常用of。
    5:15aquarterafterfive/fivefifteen9:30ninethirty/halfpastnine9:45aquarteroften/nineforty-five9:55fiveoften/ninefifty-five
    今天的內(nèi)容就介紹到這里了。
