高分语法讲解2

考点四 名词(词组)作定语 oCK n  
名词修饰名词作定语的现象在英语中也屡见不鲜, 此时前面的名词相当于形容词的作用, 只是依英语习惯决定究竟用名词还是形容词作定语, TOEFL有少量题涉及这一问题 iP?lP= M  
这样的词语有:word order(词序), taxi driver(出租车司机)等 n,p \~Tu,  
例题: :x!'Eer n  
(1) <fDbz1Q;l  
Situated in the heart of a grain-farming and livestock-raising region, Abilene, Kansas, c}2"X,  
 A                       B &qm:36Y7Xg  
is a prosperous trading and distribute center. raZ0B,;eFu  
   C         D }5u;'>$  
答案: D hNF,sA  
应改为: distribution/ distributing. v2 >Dn =V  
解释: 动词distribute不能修饰名词center,可改用名词或分词, 但此题中名词distribution作定语更符合英文习惯 ?1H>k<Jp  
(2) 0fa8.g#I$  
Acrylic paint enables artists to experiment with many colors effects. M:%Ll3  
   A  B      C         D rTeADu_vf  
答案: D (U*Zz+ R   
应改为: color 8qs8QK  
解释: 此处名词color作effects的定语无需用复数, 意为色彩效果 p49T3V  
I! ~3xZ   
DE$T1pFV  
第二章 形容词 [Ib17#74  
nY?X@avo>  
形容词即strong, attractive等描述性的词汇,在句中主要作定语修饰名词,同时还可作表语、宾语补足语等成分 !jN$U%/,%.  
P1 "g62R  
第一节 形容词修饰名词 /O$)m[  
fXAD~7T*s  
形容词最主要的功能就是修饰名词,如:modern art, electric current, great responsibility;这一考点在TOEFL改错题占有相当的比例,几乎每套题都包含一道以上的题目考形容词修饰名词,主要形式是将本应该使用形容词的位置误用为名词、副词等 @Hst-H.l<l  
例题: z9^_5la#  
(1) ~#iAW@  
The human body relies on certainty nutrients for its survival. +9_E+H'?!  
       A  B   C          D fU4{4M+9"  
答案:C liVDBbS_A?  
应改为:certain. q<A,S8'm  
解释:certainty是名词, 意为确定性, 不能修饰名词, 改为形容词certain, 表示某些 GoG_4:^#h  
(2) ^4>Icz^ F  
Textile art is known for both its tactile and vision qualities. V;]U]   
  A       B         C   D 6bt{j   
答案:C %gXNWxv  
应改为:visual. IV$2`)[A&X  
解释:vision是名词, 不能修饰名词qualities, 要用它的形容词 iTeFy -Ct  
注意1:大多数形容词既可以做定语也可以做表语, 有少数形容词一般情况下只能做表语, 比较下面两句话: bl;v^ HR0)  
The man was awake. O}"fhMk  
There was an awake man. (此句错误, awake不能做定语) `jCq`-.  
这类形容词包括: alone, afraid, alike, alert, aware, alive, ashamed, content, unable s&qr2'F+z  
例题: v:@ud,d<  
(1) M.}QXta  
Many television newscasters make the public an eyewitness to the news by means =_H)5I_\  
     A                 B        C Jl,\^)DSw  
of on-the-spot, alive reports. iMOf];O)  
       D \)9R1zp/x  
答案: D z50f$ !?  
应改为:live (adj. 现场的, 实况转播的) WjMP]ND#c  
解释:alive不能做定语, 只能做表语,所以应该改为live reports (现场报道) U*em)/9  
(2) -<B{?D  
Alike ethnographers, ethnohistorians make systematic observations, but they also  <(-4?"1  
 A              B               C X+XbIb UuL  
gather data from documentary and oral sources. ecy41y'~:  
                 D &:)e   
答案: A k~b8=$  
应改为:like g edk  
解释:alike不能做定语, 只能做表语; alike/like 是TOEFL改错中常考的考点 ZI#Xh5  
注意2:形容词词组修饰名词时要发生后置现象, 避免产生头重脚轻的感觉. XG}pp`{o  
如:a room bare of furniture, the form dependent of the contents等, 7 }sj&  
注意3:形容词修饰名词的语序也是TOEFL考点之一。 当多个形容词(甚至包括指示代词, 冠词和所有格)并列放置于名词之前时, 它们之间就存在着谁排在前面, 谁排在后面的问题, )hai?v~g   
一般来说:这个排序的规则是:  %;9+`U  
冠词(a, an, the)/所有格(my, your等)/指示代词(this, that等) + 数量形容词 + 描述性形容词 + 名词  XS/5y(W  
如: two young American students C\dlQQ  
    my three red pencils >#\&%0OZw  
第二节 比较级 JP<Z3 A2q  
英文中形容词在进行比较时需变为比较级,主要有两种形式: < =,KP)   
在词尾加-er (单音节形容词),如:fast-faster, large-larger, busy-busier, big-bigger等; 1"CbuV 6  
或在词前加more (多音节形容词),如:more useful, more complex等 ~X -.@k'  
少数词比较级形式特殊,如:good(well)-better, bad(ill)-worse, many(much)-more, little-less, far-farther(更远的)/further(更进一步的), (_lc< Bj  
oFRb+H(E  
O}3M+  
考点一 含有标志词than OAQ'/{~7  
1.最常见的比较级句式是由连词than引导比较的对象, XJ;JDch  
如:It takes less time to go there by air than by train. q qYH}%0dz  
  She possesses more books than I do. o*u A+7n  
  He is more intelligent than I expected. =>CrZ23B "  
than可视为比较级的标志词,在填空题中, ~U~4QQV  
空后含有than的, 通常空格处需要填比较级, xf@D<}~1  
空格前含有比较级的,通常空格处需要填than引导的从句。 rLcQG  
例题: <ZNa`  
(1) &7X0 ;<  
Maine has ---- weather than most of the other states in the continental United States. C6 eon4Ut  
(A) coolest !m1pL0  
(B) the coolest w`VmN}pR  
(C) cooler |[TH ~ o  
(D) the cooler 2Xgw7` !L  
答案:A 0nz k?iP  
解释:标志词than意味着应用比较级,A, B可先排除;D多the; 只有A正确 I=^%l7  
(2) 4f"a/(>*  
Pennsylvania has the most institutions of higher learning than any other state has. b,G+=&6u  
           A   B              C     D b \?#O}  
答案:A Y^S0K'N  
应改为:more R< xxwjt  
解释:标志词than表明此句应用比较级,而不是最高级 $zz=>BOk  
2.为避免重复,than之后的从句中有些成分可以省略,只把相比的部分突出出来: sa+:c{  
情况1: 用指示代词that, those来代替省略的部分, Z#;ieI\  
如:The population of China is much larger than that of Great Britain. mXF pGo5 s  
   (that 指代the population) zAB-kE\ )  
  His designs won more acclaim than those of his fellow colleagues. ;Xgy2'3  
   (those 指代 designs) kZGhE2np  
情况2: 在省略的过程中,若than之后从句的谓语部分相同, 比较的是主语部分, 那么谓语部分通常用助动词do来代替, 并且习惯上将从句主语和助动词倒装 (do + 主语) x)vYc36H  
如:The actors usually capture greater attention than do the playwrights who may YQX>)'  
    probably contribute more to the success of a play. p|Rxy"}  
例题: dt3Vy*zL  
Mammals have a larger, more well-developed brain ---- other animals. J(/ eR,ak  
(A) than do >cM U<'&  
(B) that are having _W#27I  
(C) which have  |Be.r{l  
(D) that do 9fl !CG  
答案:A YN>#zr+ ~  
解释:空格前出现了形容词比较级,空格后是比较对象,应由than连接,选项中只有A符合条件,其中由助动词do引起了一个小倒装 /e{Oqhf[n  
"l +Jx|h\  
考点二 (not) so /as…as 'T|.<u@~  
比较级特殊句式(not)so/as…as 表示“如同……一样、不如……”等意思,其结构和than句式相仿,但as…as之间的形容词必须用原形,而且as…as必须搭配使用, J;_JH lK  
如:It is as good as it looks. 9 '5,V{pj  
  The boss is not so bad-tempered as you have described. Tu/JhP/g,`  
填空题中常给出句子的一部分(第一个as),要求填出相搭配的部分(第二个as),一定要形成对这种搭配句式的敏感。 053W2Si   
例题: V">Uh@[J_  
(1) +Qc^A  
The best way to control rats is by seeing that they have as ----. {8B\-LUR  
(A) possibly little nourishment =$`DBLX   
(B) nourishment possibly little ] &G5/ ]f  
(C) little as possible nourishment BxZop.zwE(  
(D) little nourishment as possible ?4lAL  
答案:D G0]n4"~+?  
解释:空格处需要动词have的宾语,同时包含as…as句式,A、B都缺少与as搭配的结构,C语序有误,均可排除。D中as…as possible, 为固定用法, 意为“尽可能”. BgpJ;D+N4  
(2) U.^)|IHW  
There is evidence that prehistoric humans used fire ---- 400,000 B.C. >$Fc=~;Ba  
(A) so early U<6k!Y9ny  
(B) the earliest 'g=yJ  
(C) as early as 'Yd%Tb|*  
(D) so early that M3t_!HP}!  
答案:C ToMX7xz6  
解释:依句意空格处需要“早在”这一意思的正确表达,只有C符合题意,用的是比较级特殊句式as...as =V,'f  
_ma4  
考点三 the same…as #63/;o:l$  
此句式也常用来表示“和……一样”,the same和as既可连用,也可分开使用, l.34 h  
如:She looks just the same as before. VmUM _Q~  
  I got the same feeling as you did. n]$vCP  
改错题中常将此句式误用为the same…like /than, 要练就一双火眼金睛将其识别出来 |@@mq!>-  
例题: tm|lqa  
(1) R/Y/#X^b  
Meadowlarks are about the same size than robins, but they have heavier bodies, hx2C<;s4  
         A       B          C `?D_=Gw  
shorter tails, and longer bills. -DuiK:mp  
            D bNaUzM!,H  
答案:B qIqk@u  
应改为:as. O)5PUyC:H  
解释:the same as是固定搭配, 表示“与...一样” 2s4= %l  
(2) a:| 4q  
Due to sophisticated transportation networks, people can now buy the same types of 7 IHD?pnZ  
  A                 B    ( Lu.^  
perishable goods in Toronto like in New York City. dI 5sqM:  
   C          D hZ'oCRM  
答案:D 28)TXR r-  
应改为:as #VOjnc/rW  
解释:与the same相搭配的只有as, like不行 _eQ P0N  
tT8jC:oVa  
考点四 the more…,the more… cV{ZD q  
此句式常表示“越……越……”,more在此处泛指比较级,此句式的特点是前后两句以逗号隔开,句子结构平行,而且谓语动词一致时,为避免重复常进行省略, pNqf2CnnT  
如:The more she slept, the less comfortable she felt. ommKf[h%i  
  The greater the size, the easier it is for you to spot. 5i/E=D  
填空题中常需填入两个分句之一,因此看到the more结构,要注意选与其结构相近的另一半the more句式 HEuM"2{DMM  
例题: {\aSEE /'  
(1) jSFN/C.9h  
The greater the population there is in a locality, ----for water, transportation, and disposal of refuse. #c^Q<&B  
(A) the greater the need there is zkp Apj].  
(B) greater need Ke ?uE  
(C) is there great need bS<@Rd{g  
(D) the great need }K>H S\e  
答案:A H<;Fb;b  
解释:这是典型的 “the more…, 5|R2cc|"9  
y@M}T{,/  
2\w=U,;(  
the more…” 句式, 意为 “越…, 越…” 其逗号前后两部分结构要平行, 而且后一句可以不倒装, A 完全符合要求. C D 都缺少此固定句式所要求的第二个比较级; B 少定冠词the. 此句亦可改写为: If there is greater population in a locality, there will be greater need for water, transportation, and disposal of refuse. 7rSUSra  
(2) VM]IL%AN  
The less the surface of the ground yields to the weight of the body of a runner, ---- to the body. s3-ktZ@  
(A) the stress it is greater >'6GcnEb4.  
(B) greater is the stress %;Z bQ9  
(C) greater stress is #eC;3Kq#-  
(D) the greater the stress  M_1Tx  
答案:D Uk:.2%S2  
解释:此句涉及比较级的特殊句式the more..., the more..., 此句式要求前后结构平行,当谓语一致时,后面的可省略,符合要求的只有D _g 4 /%  
eFSC^  
考点五 no longer /not…any longer *yaX:,'\$  
no longer /not…any longer和no more/not…any more都表示“不再……”, VxN64;|=  
如:He no longer smokes. / He doesn't smoke any longer. 0sd-s~;  
注意no longer /not…any longer不要混用,no more /not…any more同理,这一句式在改错题中出现。 h)_Gxe "x  
例题: Y_@"v# ,  
(1) =u8D!AxT  
  Although it is any longer the big business that it was in the forties, radio 5Vi]~dZu7  
          A           B      n`)7Y`hBhP

    C                           D X B*}P  
答案:A 4C1FPrh  
应改为:no longer. 0i\',h}9  
解释:根据句意此处应为否定“不再是 ...”,英文中有两种方式表达此意, no longer / not...any longer, 此句只能采用前者, 若用后者语序应为: it is not the big business that it was in the forties any longer
