基数词数词分为基数词和序数词。表数量的词为基数词,表顺序的词为序数词。(1)基数词的表示法①十位数和个位数之间加连字符“-”。百位数和十位数(若无十位则和个位)之间用and相连。threehundredandthirty-six336②四位数及以上数字的读法:从右向左数,每三位数用逗号隔开,第一个逗号读thousand,第二个逗号读million,第三个逗号读billion。274,350,296,501读作:twohundredandseventy-fourbillionthreehundredandfiftymilliontwohundredandninety-sixthousandfivehundredandone③英语中“万”这个数量是用“十千”来表示的,而“十万”在英语中则用“百千”来表示。tenthousand一万onehundredthousand十万(2)基数词的用法①用于名词之后表示顺序编号。Please

序数词(1)序数词的表示法①第一至第十九,除第一(first)、第二(second)、第三(third)外,其余均在基数词的后面加-th构成,但fifth,eighth,ninth,twelfth的拼法与基数词有区别。②以ty结尾的整十数,将ty变为tie,然后再加-th。twenty二十→twentieth第二十③hundred,thousand,million的序数词均是在其后加-th。④几十几及以上的序数词,其中十位数、百位数和千位数等用基数词,只有个位数才用序数词。口诀记忆基数词变序数词基变序,有规律,词尾加上-th(fourth,sixth)。一、二、三,特殊记,结尾字母t,d,d(first,second,third)。八去t,九去e(eighth,ninth),ve要用f替(fifth,twelfth)。ty将y改成i,th前面有个e。若是碰到几十几,只变个位就可以。(2)序数词的用法序数词前加the,表示“第几……”;当不定冠词a/an用于序数词前时,表示在原来的基础上“再一”,意为“再一,又一”。the

分数、百分数和倍数表达法(1)分数分数由分子和分母组成。分子用基数词表示,分母用序数词表示。分子是1时,分母(序数词)用单数形式;分子大于1时,分母用复数形式,即序数词加-s。当分数前面还有整数时,要用连词and连接。

口诀记忆英语分数巧记英语分数不费事,“母序子基四个字分子若是大于1,分母还须加-s。(2)百分数百分数中的百分号“%”读作percent,无复数形式。forty-fivepercent45%

fivepercent5%含分数或百分数的短语作主语时,句子中的谓语动词的单复数形式取决于短语中的名词。Aboutonefifthofairconsistsofoxygen.氧气约占空气的五分之一。SeventypercentofthestudentsarefromChina.70%的学生来自中国。(3)倍数英语中常用twice表示“两倍”,两倍以上用“基数词＋times”表示,倍数常用于比较级前。Thisroomistwicelargerthanthatone.这个房间是那个房间的两倍大。考点4

不确定数字的表达(1)hundred,thousand,million等数词前面有基数词或某些表示数量的形容词时,不加-s。two

thousand

teachers
