第一章 名词 y6\ [1nZ

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 H f!9`R[  
iXt4|0  
;b{pzIe=F  
(2) Doctor are discovering that there is a strong psychological component to chronic i0i.sizu  
   A               B   C          D *pDXcURw  
pain. )i},@T8[  
答案:A ;bUJ+6f:  
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$}'t  
3.通常只以复数形式出现的词语, 如: ~(Ih~/5\^  
clothes       trousers       compasses(圆规)       scales(天平)       savings(储蓄), PV5TG39qQ  
statistics(统计数据),             headquarters(总部), * K0j5dx  
4.复数形式有特殊意义的词语, 如: #QJ4o_  
goods(货物), manners(礼貌), troops(军队), authorities(当局) R#[QoyJ  
e/m'a|%:  
5 不规则的名词复数 N3S,33 8s  
child - children             mouse - mice                   louse - lice - eSPoZ  
tooth - teeth             foot       - feet m!FM+kge  
IPr*pQ{;c  
6.注意:有一些结尾是-s的词, 但是要当作单数看待, 如: physics, politics, mathematics是表示学科的不可数名词 Z L6~Eut  
p``;!3~ ~  
例题: :$X4#k<  
a[d{>Fb.  
(1) With the incorporation of jazz history into current academic curricula, leading Gdc ~Lh  
       A            B           C !h`cXY~ w  
jazz musicians are now founding on the faculties of several universities. w<I5@)i|  
            D D>"{H7m Y  
~#N.!e4  
(2) W?4&lC^G  
Like some other running birds, the sanderling lacks a back toe and has a three-toed a?xq*|?  
  A      B           C           T9XW%/n  
feet. f)ucC$1=  
 D Y9I #Q  
答案:D b;~EJ  
应改为:foot 2y .-4?e  
解释:feet是foot的复数形式, 不定冠词a 之后应接可数名词的单数, 故将feet 改为单数 j 44bF/  
词汇:sanderling: 三趾滨鹬 >X\s[d&(  
xTksF?u)  
第二节 限定词 8wH41v67F  
名词究竟要用单数还是复数, 与名词之前的限定词有很大关系, 限定词通常分如下几类: \ 3js}  
1.之后肯定接单数: %RT6~0z  
a /an, every, one, another, each, either, this, that, such a, many a, etc. B3g82dm  
例句: Each of them has two books. :vgh KI  
You can read either book. (两本书你可以随便读一本) R1b )   
'@}?NV0  
2.之后肯定接复数: +y{93nl  
these, those, many, such, other, &:e}4/G  
大于one的数词(ten, hundred, thousand, million…), ]cGz~TN~  
a few /few /fewer /fewest, a (great /good / large /small) number of, several ym,Ot1  
one of, all (of), some /any (of), most (of), a lot of, lots of, the rest of, plenty of n[cyK$"  
 _. 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 $=QGua V  
KiRt '  
SUnmp  
Ca k/#1  
考点一 否定限定词no /x8C70W^  
M]/wei"X  
(1) no既可用于可数名词复数前又可用于单数前, 表示否定意义. 例如: ??e#E [bI  
No flowers in the garden. 花园里没有花. ]JCB^)tM  
No one is here. 5P t}  
:7PSZc:xE  
(2) no与否定副词not的区别是改错题的常见考点。 二者的区别在于: a ~iEps  
no直接修饰名词, 不能与其他限定词同时出现; t=pkYq5t8  
not一般出现在be动词或助动词之后, a, an, any等限定词之前, 它是否定式的组成要素, 而不是名词的限定词 d(B;vL@R2V  
~JmxW;|_x)  
例题: O@(.ei*HJ!  
(1) &=yqWW?  
The mechanism by which brain cells store memories is ---- clearly understood. d8q$&(]<  
(A) none HgBEV  
(B) no uY%3X/^j  
(C) not  E_I6  
(D) nor ~x^+OXf!^g  
E|A_|FS&%  
答案: C #FDu 4xi  
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

Frances Perkins became secretary of labor. F^v{Jqc  
        D ;8x^9Q  
 D) eKq!_  
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 f6uIF  
iQR}) =Q  
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 , &f20o  
vK>^#b3  
例题: Mj;'vm7#'

the lives. @g2L=XF  
 D TBp5xz`  
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  
hfc!M2 /w  
(2) >#|Q,hVU5  
A liquid is similar to a gas because has molecules are not fixed to each other in any /;ITnG

specific way. nuA!Jln_  
    D ,i.P= o  
C#0Wo  
答案: B sVnu Sm  
应改为: its g?M69~G$:x  
解释: has是动词, 不能修饰名词, 且与从句的谓语冲突, 依句意改为物主代词its作molecules的限定语 +rX,Sl`/  
%;J`dM  
考点三 只接复数名词的限定词 wQ.zj`?$(  
xI8*sTx 6  
a (large /small /great /considerable /remarkable) number of, a variety of, a set of, a few, 等表示数的固定词组之后总是接复数名词 *?'T8yf^

relating those objects. h]$zub  
 D p(>'4#|qy  
{BU,kjv1g  
答案: B z{x -Vfd  
应改为: is a set us+adS.l&  
解释: a set of是固定词组, 表示一套、一组, 后面接可数名词的复数, 与题中objects吻合 Y$^QH.h  
\266N;JrN  
(2) /-lmfpT  
At birth, an infant exhibits a remarkable number of motor response. ,s K-gw  
A       B     C           D c,^-nH'X>  
CqV \:50g  
答案: D R,lr&;a8  
应改为: responses %94"e7Hy  
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  
The number of boys in Class Five is 25. (五班男孩的数目是25, 后面谓语动词用单数) RP$A"<goP  
A small number of families are able to afford an apartment. (少数家庭能够买得起一套住房, ) "+AD+D  
!Fi)-o  
第三节 冠词作限定词 s0SB!-Vjm  
>e%Po,Fg$  
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

答案: B有错 &nq[Vy0kO4

考点二 定冠词the rUlXx5f  
定冠词限定名词时主要表示特指,针对TOEFL应注意以下几点: tFG&~tNc  
(1) the和可数名词单数连用,表示一类人或物,如: ,}J(&  
the fern(蕨类), the wallflower y3d`$'7H>

第四节 不可数名词 |W*#N8I P  
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-|

English(英语),    music(音乐),            management(管理), 1 R,SA:L$  
enthusiasm(热情)    work(工作),            happiness(高兴) x7GYWK 9  
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

物质名词如: _1G;!eO

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?-

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。 gB>AYL%o=
