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 FqxOHovE

考点一 单复数 + 4g%?5'  
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。 bM0[V5:jB  
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。 {dx /p-Tv  
例如:various colors(various是各种各样的,后面当然要用复数形式) \ e8*vos  
M|#5gKXd  
下面我们会讲一下复数形式。 E D^rWE_  
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: F2`htM@,  
1.结尾是s, o, x, ch, sh 的词, 加-es, 如:buses, tomatoes, faxes, matches, brushes e_k _ ty`  
2.结尾是“辅音字母+y”的词, 去掉y加-ies, 如: factory-factories L sDzV)  
3.结尾是f, fe的词, 去掉f, fe加-ves, 如: half-halves, knife-knives $`5lvy^  
4.结尾是o, f 的词也有一些加-s, 如: photos, beliefs, chiefs n~ >h4=h

   A         B           C       D mOgOHb2  
答案:A >6[ X }  
应改为:Flowers ( OyY_`  
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 i$JG^6,O

答案:A ikY]8BCc  
应改为:Doctors Z6R: rq  
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 '9 *|N=  
考点二 复数形式特例 5]H))}9>d  
s("Cn/ZkS  
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 :otY;n-  
1.单复数词形相同 V5u}C-o  
如: people, fish, Chinese(某国人), aircraft, means, series, species,sheep, deer, aircraft等 \,l.p_<  
s!@=rq  
2.外来词保留了原来的复数形式, 这一点需要重点掌握, 如: sb}K% -  
basis-bases                   analysis-analyses             crisis-crises *>aZc::  
medium(媒体)-media       datum(数据)-data             curriculum(课程)-curricula 0q[p{_t`  
larva(幼虫)-larvae             criterion(标准)-criteria       phenomenon(现象)-phenomena 29a_ZU7e6  
~U"by_  
3.通常只以复数形式出现的词语, 如: ASKAgU"h  
clothes       trousers       compasses(圆规)       scales(天平)       savings(储蓄), I|KY+k> /  
statistics(统计数据),             headquarters(总部), YY#s=  
4.复数形式有特殊意义的词语, 如: 5\akI\  
goods(货物), manners(礼貌), troops(军队), authorities(当局) 5)d,G 9  
5JBB+g  
5 不规则的名词复数 "UQr:/

tooth - teeth             foot       - feet c*x J=Gz6d

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 35Ai;mU'

答案:D S5uJX#*;  
应改为:foot PT3>E5`Nu  
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 /8f>':zUb  
词汇:sanderling: 三趾滨鹬 *:a'GC%/

第二节 限定词 $aB / +,  
名词究竟要用单数还是复数, 与名词之前的限定词有很大关系, 限定词通常分如下几类: ?q\FLb%"7  
1.之后肯定接单数: 4HM;K_G%{  
a /an, every, one, another, each, either, this, that, such a, many a, etc. eymi2-a<  
例句: Each of them has two books. {}V$`L8

2.之后肯定接复数: xpF](>LC(

考点一 否定限定词no _g[-=y{Bb  
5y]io Jc9-  
(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: ^=^$tF  
No flowers in the garden. 花园里没有花. JBz}|M D  
No one is here. n@hl2M6.x9  
[& ^RP,N~  
(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: Oa! m  
no直接修饰名词, 不能与其他限定词同时出现; /t*YDWLg  
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 [F+,YV%t

答案: C UX2lPgKdLz  
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 E =AVrv5T

        D | kXm}K  
Y/fJQ6DY  
答案: A Mzkkc QLK  
应改为: No Qhn;`9+L  
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 |quij0_'e  
0fArF*  
考点二 their等物主代词  )h_8vO2  
`s"d]/85VW  
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 XRtD< jlA"  
j}f[W [2  
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 2eb1 lJdS  
例如:Manufacutrers of consumer goods often change the styles of their products. 7K;!iX<d  
这里用their 而不用 the :Ht; 0|[H

 D Bc5+ss  
.; Q:p*  
答案: D 646JDX[o  
应改为: their EGVM)ur  
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 |nUl\WRd\

    D zp}eLm:=d  
tq1CwzRX  
答案: B ^h' Sla  
应改为: its <ABX0U[*  
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 $sHP\{

Vtc36-\1*  
答案: D "k*PA\U  
应改为: responses AjcX  N  
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 @SZM82qU2z  
?0? R  
注意 “the number of” 和 “a number of”的区别 p&+;w

第三节 冠词作限定词 yjfat&$

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。 L}@c6fHG  
U2uF&6v  
考点一 不定冠词a / an .>Ljnk  
H*#s }9=kZ  
不定冠词a和an后面当然接单数,a和an 的主要区别是: ?5_7;Ha  
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 _g1b{$  
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 UnI 48Y  
0-~\ W(  
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). x|yEt O&

JAX*hGhkh  
考点一 与可数名词的显著区别 R5 9S@MsuD  
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, By9*1H2R  
如:a sheet of steel(一片钢),             a piece of furniture(一件家具), 1PP $XJtyD

2. 不可数名词不能直接出现在不定冠词a, an之后 0 SNIYkGE  
不能够说:an advice(一个建议) ,而应该说 a piece of advice q11>f   
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, 3 "Q=Vl"  
而可数名词一般直接用原形表示种类 naw0$kXTA

(D) drops their <]T`3W9  
答案: (B) 9!Ar`Io2@
