高分语法讲解2

考点四 名词(词组)作定语 f3 v F"O  
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 $''UlWK  
这样的词语有:word order(词序), taxi driver(出租车司机)等 :BD>yOlG  
例题: ,rai%T/rL  
(1) ~j"3}wXc5  
Situated in the heart of a grain-farming and livestock-raising region, Abilene, Kansas, g YUTt  
 A                       B MMd.0JuaO  
is a prosperous trading and distribute center.  n}OU Y  
   C         D 'yr{^Pek  
答案: D |'$ l7  
应改为: distribution/ distributing. +GeWg` \=  
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 Mq'IkSt'  
(2) 9go))&`PJL  
Acrylic paint enables artists to experiment with many colors effects. O|e}   
   A  B      C         D ``4?a7!!  
答案: D QNpu TZn#Q  
应改为: color WFDCPQ@  
解释: 此处名词color作effects的定语无需用复数, 意为色彩效果 9!#EwPD$#  
EEwWucQ  
n NQ-"t  
第二章 形容词 Mk5RHDh  
F#|Z# Mu  
形容词即strong, attractive等描述性的词汇,在句中主要作定语修饰名词,同时还可作表语、宾语补足语等成分 no&-YktP}  
MI*Sq\-i  
第一节 形容词修饰名词 0T9. M(  
LGVlc@0'  
形容词最主要的功能就是修饰名词,如:modern art, electric current, great responsibility;这一考点在TOEFL改错题占有相当的比例,几乎每套题都包含一道以上的题目考形容词修饰名词,主要形式是将本应该使用形容词的位置误用为名词、副词等 0Oap39  
例题: ^l(^z fsZ  
(1) t$I |E  
The human body relies on certainty nutrients for its survival. "~\*If  
       A  B   C          D Mudrg[@ `  
答案:C a+ GJVJ  
应改为:certain. GFL-.? 0  
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 J-XTN"O  
(2) ch })ivFP[  
Textile art is known for both its tactile and vision qualities. "b%FmM  
  A       B         C   D s MZ[d\  
答案:C dG0VBE  
应改为:visual. |GuEGmR  
解释:vision是名词, 不能修饰名词qualities, 要用它的形容词 9@y3IiZ"}  
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: 9o_- =>(  
The man was awake. hW' HT  
There was an awake man. (此句错误, awake不能做定语) c0[k T  
这类形容词包括: alone, afraid, alike, alert, aware, alive, ashamed, content, unable ~gddcTp  
例题:  `{}@@]  
(1)  Zi4d]  
Many television newscasters make the public an eyewitness to the news by means 8&.-]{Z  
     A                 B        C XA3s],Rk  
of on-the-spot, alive reports. o , LK[Q  
       D j)L1H* S%  
答案: D w+_Wc~f  
应改为:live (adj. 现场的, 实况转播的) Tl3"PIb  
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) D9o*8h2$  
(2) aQ|hi F}  
Alike ethnographers, ethnohistorians make systematic observations, but they also dtTlIhh1V  
 A              B               C woau'7}XOu  
gather data from documentary and oral sources. !<r8~A3!(  
                 D tcOnM w  
答案: A 5;Ia$lm=y  
应改为:like !n zGH*td  
解释:alike不能做定语, 只能做表语; alike/like 是TOEFL改错中常考的考点 >EIrw$V$  
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. 4B$bj `h  
如:a room bare of furniture, the form dependent of the contents等, &+- e  
注意3:形容词修饰名词的语序也是TOEFL考点之一。 当多个形容词(甚至包括指示代词, 冠词和所有格)并列放置于名词之前时, 它们之间就存在着谁排在前面, 谁排在后面的问题, ]^ 'ZiyJX  
一般来说:这个排序的规则是: Vp7b4n<  
冠词(a, an, the)/所有格(my, your等)/指示代词(this, that等) + 数量形容词 + 描述性形容词 + 名词 |yv]Y/ =  
如: two young American students 7K:FeW'N  
    my three red pencils } 07r  
第二节 比较级 8ds}+TtbY  
英文中形容词在进行比较时需变为比较级,主要有两种形式: SQ<f  
在词尾加-er (单音节形容词),如:fast-faster, large-larger, busy-busier, big-bigger等; e& Rb  
或在词前加more (多音节形容词),如:more useful, more complex等 UABbcNW  
少数词比较级形式特殊,如:good(well)-better, bad(ill)-worse, many(much)-more, little-less, far-farther(更远的)/further(更进一步的),  MYx88y  
v, 0<9!'v  
f4 O]`U  
考点一 含有标志词than ]_ #SAhOR)  
1.最常见的比较级句式是由连词than引导比较的对象, iNLDl~uU  
如:It takes less time to go there by air than by train. rKIRNc#d  
  She possesses more books than I do. XtzOFx /  
  He is more intelligent than I expected. 9b%j.Q-W  
than可视为比较级的标志词,在填空题中, FfSI n3  
空后含有than的, 通常空格处需要填比较级, zq=&4afOE  
空格前含有比较级的,通常空格处需要填than引导的从句。 {*fUJmao"  
例题: 5Pqt_ZWy  
(1) xT=ySa$|>  
Maine has ---- weather than most of the other states in the continental United States. K0 QH?F  
(A) coolest %I}'Vb{C  
(B) the coolest Q@Dkl F  
(C) cooler #G~wE*VR$  
(D) the cooler Gym#b{#":  
答案:A -;ER`Jqs,  
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 Yx 3|G  
(2)  ]CIe~q  
Pennsylvania has the most institutions of higher learning than any other state has. ?sE@]]z  
           A   B              C     D J@gm@ jLc  
答案:A ->3uOF!q  
应改为:more KG-y)qXu  
解释:标志词than表明此句应用比较级,而不是最高级 R` 44'y|  
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: W[fT R?n  
情况1: 用指示代词that, those来代替省略的部分, T;J7+0  
如:The population of China is much larger than that of Great Britain. nfa_8  
   (that 指代the population) zF?31\GOX  
  His designs won more acclaim than those of his fellow colleagues. qL,ka  
   (those 指代 designs) Yfe'#MKfL  
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) 9p4%8WhJ  
如:The actors usually capture greater attention than do the playwrights who may 4?v$<=#21*  
    probably contribute more to the success of a play. !"`Jqs  
例题: C_-%*]*,j  
Mammals have a larger, more well-developed brain ---- other animals. m^'~&!ba  
(A) than do Ca X^)  
(B) that are having 1z3]PA!R  
(C) which have PP],HB+*[  
(D) that do ^]i" H|(x  
答案:A qg|Ox*_od"  
解释:空格前出现了形容词比较级,空格后是比较对象,应由than连接,选项中只有A符合条件,其中由助动词do引起了一个小倒装 MCM/=M'y  
D/e&7^iK  
考点二 (not) so /as…as KM5jl9Vv  
比较级特殊句式(not)so/as…as 表示“如同……一样、不如……”等意思,其结构和than句式相仿,但as…as之间的形容词必须用原形,而且as…as必须搭配使用, q?(A!1(u  
如:It is as good as it looks. "oHp.$+K  
  The boss is not so bad-tempered as you have described. k]t,q$Vd  
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。 u2 Y N[|V  
例题: P BCb0[\  
(1) ]F !'M  
The best way to control rats is by seeing that they have as ----. JR] )xPI`  
(A) possibly little nourishment @51z-T  
(B) nourishment possibly little K!9y+%01  
(C) little as possible nourishment [?A&x qO3  
(D) little nourishment as possible yq1Gq bh l  
答案:D _cR6ik zW(  
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”. ?Y%}(3y  
(2) LFl2uV"  
There is evidence that prehistoric humans used fire ---- 400,000 B.C. !&qx7eOSpP  
(A) so early 4 tbw*H5!5  
(B) the earliest 52da]BW<  
(C) as early as mp!YNI  
(D) so early that km9Gwg/zT  
答案:C ~azF+}x90N  
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 o^8*aH)I>Y  
th5 X?so  
考点三 the same…as 9 aY'0wa  
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, #E*@/ p/  
如:She looks just the same as before. J>&[J!>r  
  I got the same feeling as you did. &\JK%X.Jlt  
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 mfj4`3:NV  
例题: s.|!Ti!]  
(1) ` 52% XI  
Meadowlarks are about the same size than robins, but they have heavier bodies, ~D<7W4c  
         A       B          C P]|J?$1K  
shorter tails, and longer bills. 1[26w_B3  
            D >L#];|  
答案:B b\k N_  
应改为:as. "2*G$\  
解释:the same as是固定搭配, 表示“与...一样” 3?!G-  
(2) JQ~y- lt  
Due to sophisticated transportation networks, people can now buy the same types of u)<Ysx8G  
  A                 B    xnJjCEZ  
perishable goods in Toronto like in New York City. szf"|k!  
   C          D ?|D$#{^  
答案:D lt@  
应改为:as 5}vRo;-  
解释:与the same相搭配的只有as, like不行 ;k9 ?  
v_y!Oh?EG  
考点四 the more…,the more… ^VSt9 &  
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, #pS]k<o%1  
如:The more she slept, the less comfortable she felt. \(.nPW]9  
  The greater the size, the easier it is for you to spot. 4^ d+l.F  
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 }"F ?H:\  
例题: Qv9*p('~A  
(1) -@EBbM&  
The greater the population there is in a locality, ----for water, transportation, and disposal of refuse. 3MNhH  
(A) the greater the need there is A)b)ff ,  
(B) greater need  ET >S  
(C) is there great need />dB%*  
(D) the great need +-Z"H)  
答案:A Cfv L)f  
解释:这是典型的 “the more…, c!'A)JD@  
fhBO~o+K>  
"D ts*  
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. tnQR<  
(2) /|4Q9=  
The less the surface of the ground yields to the weight of the body of a runner, ---- to the body. R&u)=~O\5  
(A) the stress it is greater N<#S3B?.  
(B) greater is the stress nUI63?  
(C) greater stress is 9%p7B~}E  
(D) the greater the stress .u&&H_ UmE  
答案:D T..N*6<X  
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 fP^W"y  
aGq_hP   
考点五 no longer /not…any longer c]AKeq]  
no longer /not…any longer和no more/not…any more都表示“不再……”, N>&{Wl'y\  
如:He no longer smokes. / He doesn't smoke any longer. "?2  
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。 I3}HNGvU  
例题: J)7,&Gc6  
(1) rE1np^z7  
  Although it is any longer the big business that it was in the forties, radio r+{!@`dYi  
          A           B      &X#x9|=&O  
 continues to be a medium of essential communication, especially at the local level. JEK%y Mj  
    C                           D ,mO(!D  
答案:A Q{H!s_6iyv  
应改为:no longer. hQg,#r(JE4  
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
