资源描述
我们生活在数的世界里,每时每刻都与各种数字打交道。从人口数量、价格、速度、高度、产量、时刻、年代、日期到比例、温度、银行账号、电话号码,生活中充满了数字,正因为如此,数字与计算在英语听力教学中占有相当的比重。培养自己的耳朵对英文数字保持敏感是听力训练中一项必不可少的基本功。那么怎样才能快捷有效地掌握这一技能呢?我们应从掌握数字的正确读法开始。能流利地读出各种数字是记忆数字的前提。(1)基数词的读法我们先从基数词人手。首先掌握三位以内数字的读法,因为它是多位数字的基础,一旦熟练掌握,再借助一个逗号,便可轻松应付四位以上任何庞大的数字。我们可以通过例子来说明这一点。3-5位数的读法202读作: two hundred(and)two234读作: two hundred(and)thirty-four1, 234读作:one thousand two hundred(and)thirty four但是在读法上须注意以下几点:a在英式英语中,一个数的最后两位( 十位和个位)得用and,但美式英语中则不用。如:3,077读作:US:three thousand seventy-sevenb不定冠词a只在数的开头才和 hundred,thousand 等连用。试比较:146读作: ahundred(and)forty-six2,146读作:twothousand,one hundred(and)forty sixc.1,000这个整数我们说 athousand,在 and 前我们也说 a thousand,但是在一个有百位数的数目前就得说 one thousand 试比较:1,031读作:a thousand,(and)thirty-one,1,150读作:one thousand, one hundred(and)fiftyd.hundred,thousand 和 million 这几个词的单数可以和:a者one连用,但是不能单独使用。在非正式文体中a比较常见;当我们说话比较准确的时候就用one试比较:I Want to live for a hundred yearsThe journey took exactly one hundred dayse.我们常常说 eleven hundred(1,100),twelve hundred(1,200)等,而不说 one thous and one hundred从1,100 到1,900之间的整数,这种说法最常见。5位以上数字的读法11,234 读作:eleven thousand two hundred(and),thirty-four155,721读作:one hundred(and)fifly-fivethous and seven hundred(and)twenty-one6,155,702读作:six million one hundred(and)fifly-five thous and seven hundred and two26,000 ,008读作:twenty-six million and eight326,414,718读作:three hundred(and)twenty-six mil-lion,four hundred(and)four teen thous and,seven hundred(and)eigh-teen4,302,000,000 读作:four billion three hundred(and)two million由以上一组数字可以看出,多位数由右向左每3位有一逗号,这个逗号的作用非同小可,在记忆数字时,它可以帮我们很大的忙!逆向第一个逗号读 thousand;向左再推三位,第二个逗号读 million;第三个逗号读billion;第四个逗号就是 trillion。这几个逗号的作用在于,当我们听到若干 thousand 时,立即写下这个数,并在其后打一个逗号,并留出3位;当听到若干 million,则写下数字,并在其后打一逗号,留出6位;听到若干 billion,方法同上,在后面留出9位,后面的million、thousand 依此法类推,让所有数字各就其位。例如,当你听到twenty thous and andfour写出20,and four意为后一组仅有个位,即:004,那么,这个数字完整地写下来就是20,004;若听到 six million twenty thousand four hundred and twenty-three, 则第一步先写:6,020,再将最后一组423 写在第一个逗号后面。完整的翠字为6,020,423 。若听到One billion,one hundred and four million,twenty thousand four hundred and twenty-three:主第一步写出1,104 ,第二步接下去写第三组020,第三步二写423,这样得到的完整数字便是 1,104 ,020,423 ,由此:见这个三位一逗号的作用有多大。只要我们在平时的训练中加强对三位数读写的训练,能分辨ty与teen ,并能借助这个不可缺少的 逗号,无论数字多么大,也不会对我们造成障碍。Unit One Numbers 数字听写训练1.Look at the calendar below.Circle the birthdays that you hear.In my family there are seven people.My fathers birthday is on July 29th.My mthes birthday is on November 24th.My older sisters birthday is on May 14th.My older brothers birthday is on June 30th.My younger brothers birthday is on October 24st.My younger sisters is on April 10th,and my birthday is on December lst.2.Listen to the tape and write as much information in the chart as you can.Bart:Listen,Carolyn,I just remembered.I need to got to the bank to cash some travellers cheques.What time to they close?Carolyn:The bank close at three-thirty.Bart:It closes at three-thirty,right.Carolyn:And opens at nine-thirty.Bart:And opens at nine-thirty in he moming,ah thats good.And also-um-I need some stamps,to send some postcards.Um-what time does the post office close?Carolyn:Well,the post office doesnt close until five-thirty,so lyou have plenty of time.Bart:Yeah,thats no problem,right,OK,And-um-another question I had was-what is the best way to travel around London?Carolyn:Oh.buess are by far the best way to travel.Bart:Yeah,and do they run all night and.?Carolyn:Er-yes,as a matter of fact they do,they start at five.Bart:They start at five,yeah.Carolyn:.and run to midnigh.Bart:Yeah.Carolyn:.and then other buses run throughout the night until morning,finishing in the morning.Bart:OK,From special please,you mean?Carolyn:Yes.Bart:Yeah,right,Good,and what about the Underground,is that-er-the same?Carolyn:Undergrounds about th same.Bart:Yeah,starts at five and.Carolyn:Finishes at midnight.Bart:.finishes at midnight,right.Robin:You know,the only times you really need to get right are the pub opening times.arolyn:Pub licensing hours are ridiculous.They open about ten to ten-thirty,close at three,open in the afternoon about five-thirty,and close again at eleven p.m.Bart:Eleven!Carolyn:Yes,eleven!Bart:You mean I cant drink after eleven oclock?Carolyn:No.Bart:Oh,thats amazing!I.I cant believe that!Number threeLook at the pictures.You will hear people talking about when five ofthe situations shown below will take place.Match the conversations with the correct pictures and write down when they will be.Sue:By the way,Aidan,can you tell me when the French history exam is?Aidan:Its next week on Tuesday,a week today but theres a notice up for it if you have a look.Fred:Oh,by the way,what times that meeting on Monday?Julie:Oh,its in the afternoon.Three oclck.Fred:Right.Mechanic:Hello.Mr Cowin:Hello,Im phoning about my car.Mechanic:Er,Whats the name,sir?Mr Cowin:Em.Cowin.Mechanic:Cowin,just a minute.Ah,yes,Er,should be ready late tomorrow.Bob:Whens the talk?Jenny:Its next Wednesday,its been change
