第二篇:初中英语—数词
初中英语—数词
数词分为基数词和序数词两种。表示数目或数量多少的词叫基数词;表示数目顺序的词叫序数词。
一.基数词
1.基数词就注意以下几点:
(1)几十几的基数词的十位数与个位数之间要用连字符“-”连接。如:
eighty-five 85
twenty-six 26
(2)三位数的基数词须在百位和十位(若无十位则和个位)之间用and连接。如:three hundred and sixty-five 365
two hundred and six 206
(3)基数词的复数形式。当基数词hundred, thousand, million, billion等词前有具体数词或several修饰时,必须用单数。如:
several hundred year’s ago几百年前
two thousand students两千个学生
2.基数词的特殊用法:
(1)表示“几十年代”或“几十岁”时,用逢十的基数词的复数形式。如:
in the 1990’s 20世纪90年代
in one’s twenties在某人20多岁时
(2)用在习语中。如:
in twos and threes三三两两地
二.序数词
序数词应注意的几点事项:
1.多位数的基数词变成序数词时,只需将末位基数词变成序数词,前边的基数词不变。如:forty-two 42 forty-second第42
nine-hundred 900 nine-hundredth第900
2.当序数词用阿拉伯数字表示时,必须在数字后加上序数词的最后两个字母。如:21st第21
32nd第32
3.序数词前一般要用定冠词the,如果序数词前用a或an时,则表示“又一;再一”(没有具体范围的限制)。如:
Though he had failed twice, he wanted to try a third time.尽管他已失败了两次,他还想再试一次。
The little monkey had had three apples, and he wanted to eat a fourth one.那只小猴子已经吃了3个苹果,他还想再吃一个。
三.分数和百分数
1.分数
(1)分数的分子用基数词,分母用序数词。如:
one fifth五分之一
one tenth十分之一
(2)当分子大于1时,分母用序数词的复数。如:
two thirds三分之二
five eighths八分之五
(3)当分子是1时,可以用one也可以用a。如:
a second = one second
a third = one third
(4)当分母是2和4时,分别可以用half和quarter代替。如:
a half二分之一
three quarters四分之三
2.百分数
百分数用percent表示。如:
forty percent百分之四十
three percent百分之三
3.分数、百分数与主谓一致
分数、百分数的考查往往和主谓一致相联系。当分数、百分数修饰可数名词的复数时,谓语动词用复数形式;当分数、百分数修饰不可数名词时,谓语动词用单数形式。如:Eighty percent of the students in our school come from Henan.我们学校百分之八十的学生来自河南。
Three fourths of the students in my class are interested in English.我们班四分之三的学生对英语感兴趣。
Two thirds of the water on the earth is sea water.地球上三分之二的水是海水。
四.倍数的表示法
1.表示“几倍大小(长短;数量)”,由“倍数+ the size(length, amount...)”结构组成。如:The earth is forth-nine times the size of the moon.2.表示“……比……大几倍”,由“倍数+形容词(副词)比较级+ than +被比较部分”结构组成。如:
This box is three times bigger than that one.3.表示“……是……倍”,由“倍数+ as +形容词+ as +被比较部分”结构组成。如:Our factory is twice as big as theirs.练习※答案

第四篇:2013年初中英语词性系列 名词
初中英语词性系列之名词
1.名词的可数与不可数。
可数名词指表示的人或事物可以用数来计量,它有单数与复数两种形式。不可数名词指所表示的事物不能用数来计量。物质名词与抽象名词一般无法用数目,来统计,都成为不可数名词。不可数名词前一般不能用冠词a、an来表示数量,没有复数形式。要表示“一个„„”这一概念,就须加a piece of这一类短语。要注意许多名词在汉语里看来是可数名词,在英语里却不可数。如:chalk,paper,bread,rice,grass,news等。
2.名词的复数。
(1)规则变化。
A.一般情况下加-s.B.以s, x, ch, sh, 结尾的加-es.如:bus---buses,box---boxes,watch---watches,brush---brushes.C.以辅音字母加y结尾的改y为i再加-es.如:city---cities,country---countries.D.以f,fe结尾的,去掉f或fe,变成v再加-es.(2)不规则变化A.元音发生变化。
如:man---men,woman---women,foot---feet,tooth---teeth,mouse---mice.B.词尾发生变化。
如:child---children.C.单、复数同形。
如:fish---fish,Japanese---Japanese,Chinese---Chinese,sheep---sheep.3.物质名词(不可数名词)量的表示方法。
(1)用much,a little,a lot of等表示。
(2)用容器表示。
a bowl of rice,a glass of water,a cup of tea,a piece of,orange,two glasses of milk,two pieces of paper.4.名词的所有格。
(1)名词所有格的构成法。
A.单数名词词尾加‘ s,复数名词词尾若没有s,也要加' s.the worker's bike,the Children' s ball.B.表示几个人共有一样东西,只需在最后一个人的名字后加' s若表示各自所有,则需在各个名字后' s.如:
This is Lucy and Licy' s room.These are Kate's and jack' s rooms.C.如果是通过在词尾加-s构成的复数形式的名词,只加'.如:
the students' books,the girls' blouses.(2)名词+of+名词名词是有生命的,我们就用's结构来表示所有关系。如果名词所表示的事物是无生命的,我们就要用名词+of+名词的结构来表示所有关系。如:the legs of the desk,the door of the room.但在表示名词所有格时,' s结构也常可转换成of结构。有些表示时间,距离、国家、城市等无生命的东西的名词,也可以加's来构成所有格。如:
ten minutes' walk,today's newspaper.
