数词讲解
数词1 数词的定义和种类表示数目多少或顺序先后的词叫做数词(numeral)。
数词与不定式代词很相似,其用法相当于名词与形容词。
数词有两种。
表示数目多少的数词叫做基数词(cardinal numeral),如one,ten,fifty-two 等。
表示顺序先后的数词叫做序数词(ordinal numeral),如first,tenth,fiftieth等。
2 基数词1)1-12的基数词是:one 1, two 2, three 3, four 4, five 5, six 6, seven 7, eight 8, nine 9, ten 10, eleven 11, twelve 12.13-19,皆由3-9加后缀-teen构成,即:thirteen 13, fourteen 14, fifteen 15, sixteen 16, seventeen 17, eighteen 18, nineteen 19. (注意thirteen,fifteen,eighteen的拼法)20-90等十位数均由2-9加加后缀-ty构成,即:twenty 20, thirty 30, forty 40, fifty 50, sixty 60, seventy 70, eighty 80, ninety 90.21-29由十位数20加个位数1-9构成,中间须有连字符“-”,即:twenty-one 21, twenty-two 22, twenty-three 23, twenty-four 24, twenty-five 25, twenty-six 26, twenty-seven 27, twenty-eight 28, twenty-nine 29.其它的十位数照些类推,如:thirty-one 31, forty- two 42, fifty-three 53, sixty- four 64, seventy-five 75, eighty-six 86,ninety-seven 97.2)百位数由1-9加hundred构成,如包含十位数及个位数,中间用and连接,也可以不用;如只包含个位数,即十位数为零时,则and不可省。
现代汉语数词量词
“两”与“二”的区别
一、个位数在一般量词前用“两”。例 如:~个人、~本书、~倍、~次、~ 顿、~里地
多位数中的个位数用“二”。例如:三 十~、一百零~次、五千八百六十~元
二、传统的度量衡单位—前“两”、“二”都 可以用,,以用“二”为常。重量单位 “两”前只能用“二”。例如:~亩、~ 升、~尺、~丈、
多位数中首位以后的“百”、“千”、 “万”前都用“二”。例如:四亿~千万、 三万~千人、五千~百元
四、序数、小数、分数只能用“二”。例如: 第~、~哥、~月、零点~、三十六点~、
~分之一、三分之~
增加(了); 增加到/为 减少(了); 减少到/为 增加(了) 、增长(了) 、上升(了)、 提高(了)—不包括底数,只指净增数。 增加到/为、增长到/为、上升到/为、提高 到/为—包括底数。 减少(了) 、降低(了) 、下降(了) —指差额。 减少到/为、降低到/为、下降到/为—指余 额。
AA型重叠式还可以做状语。例如:步步紧逼 节节败退 阵阵紧缩 在阳光下点点闪烁 回回去
他家回回扑空
AABB型重叠式也可以充当不同的句法成分。例 如:家家户户吃元宵。(主语)点点滴滴的心得体
会。他口口声声地叫我老师。
(“唐诗三百首、寓言四则、神州七号”的结构?唐诗是定 语还是主语?三百首是补语还是谓语?熟读唐诗三百首 , 唐诗三百首 是定中短语作宾语,还是主谓短语作宾语? 考虑到名词不坐补语,是否可以看作主谓短语作宾语。)
B位数词:表示“十”的倍数的数目。例如: 十、百、千、万、亿、兆。
C系位数词:廿、卅。只用在特定的场合。 例如:卄四史、卄四桥、五卅运动
D数量数词:俩、仨。
2.概数词:两、几、多、数、无数、多少、
数词的用法
数词的用法一、概说数词是指表示数目多少或顺序先后的词。
表示数目多少的数词电基数词,如one, five, ten, thirty, sixty-five等;表示顺序先后的数词叫序数词,如first, sixth, tenth, twenty-first等。
数词与不定代词用法相似,在现代英语中,它与不定代词、冠词、指示代词、形容词性物主代词等被称之为限定词。
数词用法相当于名词和形容词,在句中可用作主语、宾语、表语、定语、同位语等。

先说“几十”,再说“几”,中间加连字号:twenty-one(21),thirty-six(36), forty-five(45), ninety-nine(99)等。
(3)101—999的表示法。
先说“几百”,后接and,再加末尾两位数(或末位数):one hundred and one(101), five hundred and thirty(530), seventy hundred and eighty-nine(789)(4)1000以上的基数词的表示法。

数词的用法
英语数词用法归纳一、定义与分类数词是指表示数目多少或顺序先后的词。
表示数目多少的数词叫基数词,如one, five, ten, thirty, sixty-five 等;表示顺序先后的数词叫序数词,如first, sixth, tenth, twenty-first 等。
数词用法相当于名词和形容词,在句中可用作主语、宾语、表语、定语、同位语等。
二、基数词1. 英语中没有“万”这个读数单位,要表示汉语中的“万”,英语需借用thousand一词,如“一万”用“十个千”表示(ten thousand),“十万”用“一百个千”表示(one hundred thousand)。
2. 用作基数词单位的hundred, thousand, million, billion 通常不带复数词尾-s,但若用于表示数百、数千、数百万这样的泛指,则用复数。
如:About two thousand people died in the earthquake. 大约有两千人在地震中丧生。
Thousands of people go to the seaside every year. 每年成千上万的人到海滨去。
3. 表示整十的基数词用复数形式可以表示人的大约岁数或年代。
如:`He is in his early twenties. 他才二十出头(from )。
This took place in the 1930s. 这事发生在20世纪30年代。
三、序数词1. 许多序数词是由相应的基数词后加词尾-th构成的,如four / fourth,six / sixth,ten / tenth,sixteen / sixteenth,但是nine变为序数词是ninth,而不是nineth。
2. twentieth, thirtieth, fortieth 等表示整十的序数词,由相应的基数词将词尾y改为ie,再加-th 构成。
3. first, second, third 通常可缩写为1st, 2nd, 3rd。

数词用法
注意事项
• (1)十位数于个位数之间通常用连字符号“-”,一百以 上的数词通常在百位与十位之间加and,没有十位数时百位 数与个位数之间通常也要加and,在美国英语中,and往 往省去。
如: • 68 ─ sixty-eight • 156 ─ one/a hundred (and) fifty-six • 602 ─ six hundred (and) two
数词(Numeral)
• 数词(Numeral),是用来表示事物的数目 大小和顺序先后的词。数词分为两大类, 即基数词和序数词。基数词表示数量,如: one,two,three,four……;序数词表示顺序, 如:first,second,third,fourth……序数词前 一般要加the
语法特征
• 3.百分数是由基数词或小数加百分号组成,百分号(%)读 作percent,如: • 0.6% — zero point six percent • 5% — five percent • 100% — one hundred percent • 12.34% — twelve point three four percent
十二小时计时制
• • 1.十二小时计时制 十二小时计时法通常采用“小时数: 分钟数” 或“小时数. 分钟数”的形式, 如:8:12或8.12。为了避免误解,通常加上in the morning / a.m.(上午)或in the afternoon p.m.(下午)以示区别。a.m.是拉丁语ante meridiem的缩写形式,读作 /'ei'em /,意思是“上午”, p.m.是拉丁语post meridiem的缩写形式,意思是 “下午;晚上”,读作/'pi:'em/。若表示整点钟,可加o'clock,也可不加。 主要看分钟的大小:1、大于30分钟时,需要将小时加1,再用60减去分钟数后用 to连接.小于或等于30分钟时,直接在小时和分钟间加上past就可以了 8.00 a.m./8:00 a.m. 上午八点 读作:eight a.m. 或 eight in the morning. 8.45 a.m./8:45 a.m. 上午八点四十五 读作:eight forty-five a.m. 或 a quarter to nine in the morning. 2.00 p.m./2:00 p.m. 下午两点 读作:two(o'clock) p.m. 或 two (o'clock) in the afternoon. 3.30 p.m./3:30 p.m. 下午三点半 读作:three thirty p/m. 或 half past three in the afternoon 5.15 p.m./5:15 p.m. 下午五点一刻

数词的详细讲解
数词的详细讲解
数词是用来表示数量、顺序、程度等概念的词。
在中文中,数词可以分为整数词、小数词、分数词和序数词等几类。
1. 整数词:用来表示没有小数部分的数,包括零和正整数。
例如:
一、二、三、四、五、六、七、八、九、十、百、千、万等。
2. 小数词:用来表示有小数部分的数,包括小数点和小数部分的数字。
例如:零点五、一点二三、三点五等。
3. 分数词:用来表示分数的数词,包括分子和分母。
例如:二分之
三、四分之五、七分之四等。
4. 序数词:用来表示顺序的数词,通常在整数词前面加上“第”字。
例如:第一、第二、第三、第四等。
数词在中文中的使用有一些特殊规则,例如:
-“两”和“二”在表示数量时有所不同,“两”用于两个事物,而“二”用于数字。
例如:两个苹果(两苹果)、二月份(二月)。
-在表示数量时,通常使用“两”而不是“二”。
例如:两本书、两个人。
-在表示时间时,通常使用“二”而不是“两”。
例如:二月、二点钟。
-“十”是一个特殊的数词,它可以表示数字10,也可以表示“每”或“十倍”。
例如:十个苹果(10个苹果)、十分之一(1/10)。
-在表示数量时,“百”、“千”、“万”等数词后面通常会加上“位”、“个”、“条”等量词。
例如:一百元、一千人、一万本书。
这些是一些基本的数词用法,实际使用中可能会有更多的特殊情况和小技巧。
