正确区分可数名词与不可数名词、正确选择可数名词单复数、名词之前的限定词与名词数(单复数)之间的关系以及名词在句子中承担的成分是TOEFL中常考的内容 6Z$b?A3zM
y6bjJ}
第一节 可数名词 }\U0[x#q
;*_I,|A:Xr
考点一 单复数
wqf& i^_
可数名词与不可数名词的典型区别在于前者有单数和复数两种形式。 FRc |D
TOEFL考试中经常在不可数名词后面加了s,变为复数形式,其实这是再考你辨别可数名词和不可数名词的能力。TOEFL中还经常考可数名词是采用单数还是复数, 这往往要通过句意或者其他的一些指示词来辨别。 aK!xRnY
例如:various colors(various是各种各样的,后面当然要用复数形式) "\}21B~{7'
^971<B(v
下面我们会讲一下复数形式。 UQSX<6"
复数形式简而言之就是在单数词尾加-s,但实际上细分起来还有一些具体的规则: BSjbnnW}"
1.结尾是s, o, x, ch, sh 的词, 加-es, 如:buses, tomatoes, faxes, matches, brushes B{^`8Htrn
2.结尾是“辅音字母+y”的词, 去掉y加-ies, 如: factory-factories RsR] T]4
3.结尾是f, fe的词, 去掉f, fe加-ves, 如: half-halves, knife-knives 0@:Y>qVa
4.结尾是o, f 的词也有一些加-s, 如: photos, beliefs, chiefs v]l&dgoT

(1) Flower have long been cultivated and bred for their beauty and their fragrance. vI4%d,
A B C D 2&suo!ig
答案:A <XU8a:w'T
应改为:Flowers dCW0^k
解释:表泛指时,可数名词可用不定冠词加单数或直接用复数,因谓语是复数,故改为复数 Hf!9`R[

应改为:Doctors de*,MkZN
解释:表泛指时,可数名词用冠词加单数或直接用复数,因谓语动词是复数,故名词也用复数 ?v0A/68s#
考点二 复数形式特例 ';i"?D?NAk
FSI]k:
这部分主要考察学生对特殊复数形式的记忆,作为考题并不过多的出现,但是在题干中的出现率却非常高,因此熟悉下列一些词的复数形式有助于理解题意 a*
pXrp@
1.单复数词形相同 5q0BG!A%T
如: people, fish, Chinese(某国人), aircraft, means, series, species,sheep, deer, aircraft等 olUqBQ&ol
uzat."`d'
2.外来词保留了原来的复数形式, 这一点需要重点掌握, 如: Lf$Q
%eM0
basis-bases analysis-analyses crisis-crises !gD 3CA
medium(媒体)-media datum(数据)-data curriculum(课程)-curricula qk"oFP6
larva(幼虫)-larvae criterion(标准)-criteria phenomenon(现象)-phenomena >w%d'e$
SSSDl$}'t
3.通常只以复数形式出现的词语, 如: ~(Ih~/5\^
clothes trousers compasses(圆规) scales(天平) savings(储蓄), PV5TG39qQ
statistics(统计数据), headquarters(总部), *K0j5dx
4.复数形式有特殊意义的词语, 如: #QJ4o_
goods(货物), manners(礼貌), troops(军队), authorities(当局) R#[QoyJ
e/m'a|%:
5 不规则的名词复数 N3S,33
8s
child - children mouse - mice louse - lice -
eSPoZ
tooth - teeth foot - feet m!FM+kge
IPr*pQ{;c
6.注意:有一些结尾是-s的词, 但是要当作单数看待, 如: physics, politics, mathematics是表示学科的不可数名词 Z

A B C T9XW%/n
feet. f)ucC$1=
D Y9I #Q
答案:D b;~EJ
应改为:foot 2y
.-4?e
解释:feet是foot的复数形式, 不定冠词a 之后应接可数名词的单数, 故将feet 改为单数 j

词汇:sanderling: 三趾滨鹬 >X\s[d&(

第二节 限定词 8wH41v67F
名词究竟要用单数还是复数, 与名词之前的限定词有很大关系, 限定词通常分如下几类: \3js}
1.之后肯定接单数: %RT6~0z
a /an, every, one, another, each, either, this, that, such a, many a, etc. B3g82dm
例句: Each of them has two books. :vgh
KI
You can read either book. (两本书你可以随便读一本) R1b
)
'@}?NV0
2.之后肯定接复数:
+y{93nl
these, those, many, such, other, &:e}4/G
大于one的数词(ten, hundred, thousand, million…), ]cGz~TN~
a few /few /fewer /fewest, a (great /good / large /small) number of, several ym,Ot1
one of, all (of), some /any (of), most (of), a lot of, lots of, the rest of, plenty of n[cyK$"
_.
J[w6
3.之后既可接单数又可接复数: the, no, his, her, their, my, etc
p?`|CE@h7
注意:这几类词大多不能同时使用 $=QGua V

考点一 否定限定词no /x8C70W^
M]/wei"X
(1) no既可用于可数名词复数前又可用于单数前, 表示否定意义. 例如: ??e#E
[bI
No flowers in the garden. 花园里没有花. ]JCB^)tM
No one is here. 5P t}
:7PSZc:xE
(2) no与否定副词not的区别是改错题的常见考点。 二者的区别在于: a ~iEps
no直接修饰名词, 不能与其他限定词同时出现; t=pkYq5t8
not一般出现在be动词或助动词之后, a, an, any等限定词之前, 它是否定式的组成要素, 而不是名词的限定词 d(B;vL@R2V
~JmxW;|_x)
例题: O@(.ei*HJ!

E|A_|FS&%
答案: C #FDu4xi
解释: 此句主谓完整, 据选项可知空白处需填入合适的词使原句变为否定, 只有否定副词not可以和is配合构成否定句, A、B、D 之后都需要名词词组, 不符题意 ?(L?X&)v

答案: A e&7}N Za
应改为: No (C[S?@S
解释: Not是否定副词应置于be动词或助动词之后, 且它与单数名词间需加冠词, 而no是形容词, 可以直接修饰后面的名词 [0

考点二 their等物主代词 rG%_O$_dO
x@\'@>_GM
1.物主代词是常见的名词限定词, 其后既可接可数名词的单复数(his pen, his pens)又可接不可数名词(his time), 但不可与其他的限定词同时出现(部分数词除外),例如:不能说no my car, my no car,但是可以说 My two red cars 6Kc7@oO~
-Z&{$J
2.英语中许多习惯用法在表示特指时都用物主代词而不用the, 为的是更突出所属关系,这在TOEFL中是一个常考的点 aRKG)0=
例如:Manufacutrers of consumer goods often change the styles of their products. ,<WykeC
这里用their 而不用 the ,

4T^WRS
答案: D 3CRBu:)m
应改为: their cO+`8`kv
解释: 定冠词the指代不清, 用物主代词their作名词lives的限定语更符合英语习惯, 还可突出lives 与people之间的所属关系 |hyr(7

解释: has是动词, 不能修饰名词, 且与从句的谓语冲突, 依句意改为物主代词its作molecules的限定语 +rX,Sl`/

答案: D R,lr&;a8

解释: 短语a number of 后面要求接可数名词的复数, number前可加某些形容词如great, considerable, remarkable, small 等表示a lot of 或 a few WYL.J5O
COafVlJ,l
注意 “the number of” 和 “a number of”的区别 J/Li{xp)Lg

第三节 冠词作限定词 s0SB!-Vjm
>e%Po,Fg$
冠词是一个虚词,本身不能够独立使用, 必须和一个名词连用。TOEFL出题主要集中在a和an的区别,那些地方要加the那些地方不加。 Aj_}B.
ux=@"!PJ
考点一 不定冠词a / an :gXj($
hS
Sq=(S
不定冠词a和an后面当然接单数,a和an 的主要区别是:
.1;?#t]ZV
a 用于以辅音开头的名词前(指发音而不是拼写), 如: a tower, a university 0Sk{P>A
an用于以元音开头的名词前(指发音而不是拼写), 如: an orange, an hour _>.%X45xi
23PSv8;EM
不定冠词a / an与可数名词单数连用, 表示泛指 “一个”、 “某一个”, 有时还可代表一类人或事物. 在作表语或同位语的可数名词单数前一般都要加不定冠词(除非名词前已有物主代词作限定语, 如my pen). |Cm}%sgR\0

第四节 不可数名词 |W*#N8IP
LIE5of
英文中常把抽象名词和物质名词视为不可数名词, 而其划分的标准往往与汉语的习惯不同, 因此是学习英文的一个难点, 也是TOEFL中常出现的题型 w~4T.l#1
X6<Ds'I
抽象名词如: YJGP8
(不可触及的东西,表示动作、状态、品质、感情等)如: [[#zB-|
news(新闻), information(信息), population(人口), U0=: `G2l
English(英语), music(音乐), management(管理), 1R,SA:L$
enthusiasm(热情) work(工作), happiness(高兴) x7GYWK

还有表达学科类的名词如: [2{2w68D!
physics物理, politics政治学, mathematics数学, "^Vnnb:Z*o
mechanics力学, statistics(统计学) bioloby(生物学) /%1-tGh
% oJH 6F
物质名词如: _1G;!eO
equipment(装备), chalk(粉笔), glass(玻璃), 4s9qQ8?
grass(草), jewelry(珠宝) wood(木头) a$K6b5`>Rs
+2+|zXmT
"m>BE
考点一 与可数名词的显著区别 Qe =8x7oIP
1. 不可数名词没有复数形式, 其数的表示必须通过 “数词+量词+of+不可数名词” 的结构或一些特定的限定词, ;b}cn!U]
如:a sheet of steel(一片钢), a piece of furniture(一件家具), !i_~<6Wa7
two pieces of work(两份工作) an item of news(一条新闻) Q[c:A@oW
2. 不可数名词不能直接出现在不定冠词a, an之后 <UY9<o
不能够说:an advice(一个建议) ,而应该说 a piece of advice 40a
D\S>
3. 当表示一类事物时, 可数名词可以通过加a, an、加复数、或加定冠词the等方式, tIk$4)ZAl
而可数名词一般直接用原形表示种类 'w0?-
