2010年新目标中考英语词类复习
复习难点:十大词类的句法功能
复习重点:十大词类的常考点
复习方式:熟记各词类的总结、教师提出重难点、强化细节知识的考查、近年在词类方面的命题去向、强化训练
I.词法
英语中的词可以根据词义、语法功能和形式特征分为十大类,即名词(noun)、代词(pronoun)、形容词(adjective)、副词(adverb)、动词(verb)、数词(numeral)、冠词(article)、介词(preposition)、连词
(conjunctions)和感叹词(interjection)。
一、名词(n.) 表示人、事物或抽象概念的名称的词
(一)名词的分类
名词分为普通名词和专有名词,其中普通名词包括可数名词和不可数名词,可数名词可用作单数,也可用作复数。
可数名词包括个体名词(表示一类人或物的个体。如:boy,desk,cat,window)和集体名词(由若干
个体组成的集合体。如:family,class,police)。
不可数名词包括物质名词(表示无法分为个体的实物。如:water,paper,silk,money)和抽象名词(表示性质、行为、状态、感情或其它抽象概念。如:work,happiness,music,difficulty,housework)
专有名词表示个人、地方、机构、组织等。如:Tom,the Great Wall,the Spring Festival,France,the United States)
(二)名词的数(考点)
1.可数名词有单数和复数两种形式,其复数形式的构成主要有以下几种:
(1)一般情况下,在词尾加s。
eg.book——books,dog——dogs,pen——pens,boy——boys
以轻辅音结尾的名词后的s的读音为[s),以浊辅音和元音结尾名词后的s读音为〔z〕。
(2)以s,x,ch,sh结尾的词名词变复数时,要在词尾加es。
eg.beach——beaches,brush——brushes,bus——buses,box—boxes(es读音为〔iz〕
(3)以“辅音字母+y”结尾的名词,先变y为i,再加es。
eg.city——cities,family——families,documentary——documentaries,country——countries,
strawberry——strawberries(ies读音为[iz])
(注:以“元音字母+y”结尾的词,直接在词尾加-s。eg.boys,holidays,days)
(4)以元音字母。结尾的名词,变复数时情况如下:
①加es.tomato—tomatoes,potato—potatoes hero----heroes
②结尾是两个元音字母的加s,eg.Zoo—zoos,radio——radios
③某些外来词变复数时词尾加s,eg. piano—pianos
④一些名词的缩写形式变复数时,词尾加s,
eg.photo(photograph)——photos,kilo(kilogram)kilos
⑤zero变复数时,既可加s,也可加 es.zeros/zeroes
(5)以f或fe结尾的名词变复数时,先把f或fe变为v,再加es。
eg.wife——wives,leaf leaves,half——halves,knife—knives,thief--thieves(res读音为[vz]
(注意:roof的复数为roofs; scarf的复数为scarfs/scarves)
(6)有些名词由单数变复数时,不是在词尾加s或es,而是变换其中的字母,
eg.man——men,woman——women,policeman——policemen,Englishman——Englishmen,
Frenchman——Frenchmen, foot——feet, tooth——teeth, child——children,mouse—mice
(7)还有一些名词的单数和复数形式相同。
eg.Chinese,Japanese,sheep,deer,fish
(8)另一些名词本身即是复数形式,不可用作单数。
eg,people,police,trousers,pants,clothes,scissors
另外,①当一个名词作定语说明另一个名词时,这个名词一般用单数。
eg.an apple tree,five apple trees,a girl friend,two girl friends,a twin sister
但是,当man和woman作定语修饰复数名词时,就要用其复数形式。
eg.two men teachers,three women doctors
②可用“量词+of+名词复数”这一结构表示可数名词的数量。
eg.a room Of students,two boxes Of pencils
2.不可数名词一般没有复数形式,它的“量”的表示方式如下。(考点)
(1)表不定数量时,一般用much,(a)little,a lot of/lots of,some,any等词修饰。
eg,much money,a little bread
(2)表确定数量时,一般用“数词+量词+of+不可数名词。如:two/three/…+量词复数十of+不可数名词。
eg.a bag Of rice,two glasses Of milk,four bottles Of water
3.有些名词既可作可数名词也可作不可数名词,但词义有所不同。
eg: fruit水果——fruits表示不同种类的水果;food食物——foods各种食品;fish鱼——fishes鱼的种类;drink饮料、酒——a drink一杯/一份饮料、一杯酒; cloth布——,a cloth桌布、抹布; sand沙——sands沙滩; tea茶——a tea一杯茶;chicken鸡肉——a chicken小鸡;orange橘汁——an orange橘子; glass玻璃——a glass玻璃杯,glasses眼镜; paper纸——a paper试卷、论文;wood木头——a wood小森林;room空间、余地——a room房间
(三)名词的所有格(表示人或物的所属关系) (难点)
(1)有生命的名词所有格以及表示时间、距离、城镇、国家等的名词所有格。
①不是以s结尾的名词变成所有格时,在词尾加’s。
eg.Mike’s watch;Women’s Day
②以s结尾的名词变成所有格时,只加’。
eg.teachers’ office,students’ rooms
③两个或两个以上名词并列,表示共同所有,只需在最后一个名词后加’s。
eg.Tom and Mike’s room汤姆和迈克的房间(表示汤姆和迈克共有一间房)
④两个或两个以上名词并列,表示分别所有,需在几个名词后都加’s。
eg. Mary’s and Jenny’s bikes玛丽和詹妮的自行车(表示玛丽和詹妮各自的自行车)
(2)无生命的事物的名词所有格常用of结构
eg.a map Of China,the beginning Of this game,the door Of the room
(3)特殊形式
①可用’s和of短语表示的名词所有格
eg.the boy’s name=the name Of the boy(男孩的名字)
the dog’s legs=the legs of the dog(狗的腿)
China’s population=the population Of China(中国的人口)

九、动词(verb.)动词表示主语的动作或状态
(一)动词的种类。
(1)及物动词vt,其后接宾语。
eg.She wears a uniform.
(2)不及物动词vi,不接宾语。
eg :She can dance.
(3)连系动词like-v.接表语。
eg.They are nurses.

(4)助动词aux--V.接动词原形或分词(它无实在意思,只起语法作用)。
eg, DO you like pandas?

(5)情态动词mod-v.接动词原形(它不能单独作谓语,有自己的意思,无人称和数的变化)。
Eg. He must go now.

(6)有些动词既可作及物动词,也可作助动词或不及物动词,be也可作助动词。
eg.I do my homework after class.(Vt.)

(2)表示许:可、允许,意为“可以”。
eg.Can we watch TV now?

cg。it can’t be true.这不可能是真的。

(二)can与be able to的区别
1.两者都可以用来表示能力。

2.can只有现在时(Can)和过去时(could),而be able to可用于多种时态。

eg.We must clean the room.(表示我们认为房间太脏了。)
We have to clean the room.(表示没有人替我们打扫房间等客观原因。)
He must beat home before supper。(他晚饭前一定在家。)
2.人称和时态不同。
must无人称和时态的变化,一律用must十动词原形。have to后接动词原形,有人称、数和时态的变化,一般现在时的第三人称单数要用has to,过去时中要用had to,将来时中要用will have to。另外,have to还可与情态动词和助动词连用。
eg: Tom must practice his guitar every day.
The train has left.We'll have to wait for the next train.
3.否定式及意义不同。
must not=mustn't“决不可/千万不可/务必不要”;don’t/doesn’t/didn’t/won’t+ have to“不必”
eg.We mustn’t tell jokes on him.我们千万不可与他开玩笑。
We don’t have to tell jokes on him.我们不必和他开玩笑。
在对May I…? 作否定回答时用No, you mustn’t/can’t.
eg. May l go to the movies? NO,You mustn't
5.疑问式及回答不同。
Must+主语+动词原形+…? Yes,主语+ must./NO,主语+needn’t.
助动词+主语+have to+动词原形+…?
Yes,主语+助动词./No,主语+助动词+not.
eg.Must l go now? Yes,you must./NO,you needn’t
