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 4tGP- L

第一节 可数名词 ;)c 4  
P}2waJe  
考点一 单复数 q@+#CUa&n  
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。 n[f<]4<  
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。 f7du 1k3  
例如:various colors(various是各种各样的,后面当然要用复数形式) ,Oj 53w=  
wI{ED  
下面我们会讲一下复数形式。 \v,m r|  
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: &pk&8_=f  
1.结尾是s, o, x, ch, sh 的词, 加-es, 如:buses, tomatoes, faxes, matches, brushes }i\U,mH0_&  
2.结尾是“辅音字母+y”的词, 去掉y加-ies, 如: factory-factories %uUQBZ4  
3.结尾是f, fe的词, 去掉f, fe加-ves, 如: half-halves, knife-knives '*d);{D8  
4.结尾是o, f 的词也有一些加-s, 如: photos, beliefs, chiefs $Y3mO ~

   A         B           C       D wVMR&R<t  
答案:A ),%(A~\  
应改为:Flowers $ KAOJc4<  
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 b$,~S\\c

答案:A <,\Op=$l3I  
应改为:Doctors !$1'q~sO  
解释:表泛指时,可数名词用冠词加单数或直接用复数,因谓语动词是复数,故名词也用复数 ]Lz:oV^%  
考点二 复数形式特例 hALg5.E{T  
) Z^b)KAk  
这部分主要考察学生对特殊复数形式的记忆,作为考题并不过多的出现,但是在题干中的出现率却非常高,因此熟悉下列一些词的复数形式有助于理解题意 'G>gNq  
1.单复数词形相同 Z H1UAf  
如: people, fish, Chinese(某国人), aircraft, means, series, species,sheep, deer, aircraft等 f*tKj.P  
("!P_Q#  
2.外来词保留了原来的复数形式, 这一点需要重点掌握, 如: L';b908r2  
basis-bases                   analysis-analyses             crisis-crises t7; ^rk*  
medium(媒体)-media       datum(数据)-data             curriculum(课程)-curricula !YZ$WiPl  
larva(幼虫)-larvae             criterion(标准)-criteria       phenomenon(现象)-phenomena EH2 a  
QswbIP/>:'  
3.通常只以复数形式出现的词语, 如: >r8$vQGj  
clothes       trousers       compasses(圆规)       scales(天平)       savings(储蓄), "u=U@1 ^  
statistics(统计数据),             headquarters(总部), -z6{!  
4.复数形式有特殊意义的词语, 如: }]K^b1Fs5  
goods(货物), manners(礼貌), troops(军队), authorities(当局) +61h!/<W  
5U[ bn=n  
5 不规则的名词复数 DM[gjfMXu

tooth - teeth             foot       - feet A!bH0=<I  
pGHn   
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 QgB%\mO=

feet. aH(B}wh{  
 D P{tH4V23T  
答案:D 2 5m6/Y  
应改为:foot B$)&;Q  
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 B33H,e)  
词汇:sanderling: 三趾滨鹬 @5Zg![G

第二节 限定词 q\q8xF~[p  
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: {L9WeosQ  
1.之后肯定接单数: 1Ka,u20  
a /an, every, one, another, each, either, this, that, such a, many a, etc. :^H#i:4  
例句: Each of them has two books. fBZAO  
You can read either book. (两本书你可以随便读一本) Qe,aIh  
NKJ+DD:'  
2.之后肯定接复数: Wd78 bu|  
these, those, many, such, other, y?4% eD  
大于one的数词(ten, hundred, thousand, million…), 8n`O{8:fi  
a few /few /fewer /fewest, a (great /good / large /small) number of, several fO'"UI  
one of, all (of), some /any (of), most (of), a lot of, lots of, the rest of, plenty of o1B8_$aYgc  
vD@ =V#T  
3.之后既可接单数又可接复数: the, no, his, her, their, my, etc t=B>t S.hO  
注意:这几类词大多不能同时使用 QW[ gDc

考点一 否定限定词no 7%g8&d  
dd&n>A3O=  
(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: 'Bc{N^  
No flowers in the garden. 花园里没有花. I(2qXOG  
No one is here. LFHzd@Y7"  
r iuG,$EX  
(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: %n7Y5|Uh  
no直接修饰名词, 不能与其他限定词同时出现; y8k*{1MuO  
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 %hnv go:^g

(C) not yv&VK ht  
(D) nor N%:)MT,&g  
nS`DI92I  
答案: C s'Op|`&X  
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 7 g2@RKo

        D ag~4m5n*~  
&1k2J   
答案: A t(,_  
应改为: No vxmz3ht,Q  
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 Xgs 31#K  
,*Vt53@E  
考点二 their等物主代词 F N)vFQ#J  
9iWs'M  
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 /6$8djw  
=@UgCu>=  
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 V6.w=6:`X  
例如:Manufacutrers of consumer goods often change the styles of their products. G{8>  
这里用their 而不用 the |KM<\v(A{

the lives. iHp@R-g  
 D 0A7 qO1%xw  
T==(Pw7R7  
答案: D KG5h$eM'  
应改为: their BV9%|  
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 b)5z'zQu

    D ~sI$xX!  
*TjolE~o  
答案: B 0S{dnp  
应改为: its fC A/   
解释: has是动词, 不能修饰名词, 且与从句的谓语冲突, 依句意改为物主代词its作molecules的限定语 gD[ Fkq$]  
_>G=v!  
考点三 只接复数名词的限定词 !_EaF`oh(

答案: D Y$%/H"1bk  
应改为: responses ZQT14.$L  
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 g)*[W>M

考点一 不定冠词a / an m~%\f8w-x  
g{@q  
不定冠词a和an后面当然接单数,a和an 的主要区别是:   5;+OpB  
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 G#ov2  
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 (W3~r  
 ?[Od.  
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). O/^7TBTn<r

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 |'!9mvt=

抽象名词如: =v6qr~

Z3N^)j8  
考点一 与可数名词的显著区别 Lem:zXj  
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, W q"^{  
如:a sheet of steel(一片钢),             a piece of furniture(一件家具), VL8yL`~zc.  
    two pieces of work(两份工作)       an item of news(一条新闻) sG:tyv ln  
2. 不可数名词不能直接出现在不定冠词a, an之后 ;{Tf:j'g  
不能够说:an advice(一个建议) ,而应该说 a piece of advice L%31>)8  
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, H57wzG{xG  
而可数名词一般直接用原形表示种类 {LqahO*

应改为:much evidence 6/l{e)rX2o  
解释:many是复数名词的限定词,而evidence是不可数名词,应用much作限定词 %G/j+Pf  
另外一些词(词组)如such, some /any (of), most (of), a lot of, lots of, the rest of, plenty of等既可接可数名词又可接不可数名词。 al{}p  
例如: ` ;v>fTcy
