高分语法讲解2

考点四 名词(词组)作定语 KG=57=[  
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 5{xK&[wR*  
这样的词语有:word order(词序), taxi driver(出租车司机)等 msVi3`q~  
例题: O)!S[5YI  
(1) >} E  
Situated in the heart of a grain-farming and livestock-raising region, Abilene, Kansas, K|Xr~\=  
 A                       B I}+9@d  
is a prosperous trading and distribute center. I8/tD|3  
   C         D $-p9cyk  
答案: D aH_0EBRc  
应改为: distribution/ distributing. v~A*?WU;n  
解释: 动词distribute不能修饰名词center,可改用名词或分词, 但此题中名词distribution作定语更符合英文习惯 R2A#2{+H  
(2) N/zP!%L  
Acrylic paint enables artists to experiment with many colors effects. ]*hH.ZBY"^  
   A  B      C         D e^}@X[*'#  
答案: D '5(T0Ws/w  
应改为: color CK#i 6!~r  
解释: 此处名词color作effects的定语无需用复数, 意为色彩效果 p^1~o/  
&O5O@3:7]  
2w Ja:=$  
第二章 形容词 p<<dj%  
Sf*gAwnW  
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 I+,CiJ|4  
=!G{+& j  
第一节 形容词修饰名词 =Qf{  
+KaVvf  
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 eM@xs<BR  
例题: LLKYcy  
(1) .%!^L#g  
The human body relies on certainty nutrients for its survival. Q/q>mN"#1  
       A  B   C          D wD:2sri  
答案:C p1\mjM  
应改为:certain. ^X?uAX-RP|  
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 X:lStO#5  
(2) yzMGZi`ut  
Textile art is known for both its tactile and vision qualities. =\ k:]  
  A       B         C   D a`[9<AM1#  
答案:C DN iH" 0%  
应改为:visual. p I~;3T:!  
解释:vision是名词, 不能修饰名词qualities, 要用它的形容词 e0#t  
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: f7|Tp m  
The man was awake. B* Ey&DAV  
There was an awake man. (此句错误, awake不能做定语) @qYT/V*/  
这类形容词包括: alone, afraid, alike, alert, aware, alive, ashamed, content, unable t-5 Y,}j  
例题: .wmqaLd%  
(1) =6+99<G|%M  
Many television newscasters make the public an eyewitness to the news by means Ni%@bU $  
     A                 B        C +KD7Di91<K  
of on-the-spot, alive reports. " Zx<hL*  
       D :5.F  
答案: D 2Y<]X7Ch:  
应改为:live (adj. 现场的, 实况转播的) fUGappb  
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) QxN1N^a0  
(2) ^8A [ ^cgq  
Alike ethnographers, ethnohistorians make systematic observations, but they also 7(oA(l1V  
 A              B               C kN78j  
gather data from documentary and oral sources. {~u Ti>U  
                 D +iF t)  
答案: A ,lStT+A  
应改为:like RGs7Hc  
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 7Xu#|k  
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. -B9e&J {K  
如:a room bare of furniture, the form dependent of the contents等, >Q!}tbg~9  
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, \/?J)k3H.  
一般来说:这个排序的规则是: 1kw*Q:   
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 6_])(F3+w.  
如: two young American students xO Aq!,|V  
    my three red pencils ux)*B}/xh  
第二节 比较级 U1X"UN)  
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: 4xr^4\ lk  
在词尾加-er (单音节形容词),如:fast-faster, large-larger, busy-busier, big-bigger等; c9fz x  
或在词前加more (多音节形容词),如:more useful, more complex等 `=P_ed%&'  
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), 9\<q =p~  
[M,4qe8,}  
DAP/  
考点一 含有标志词than =g! Pw]  
1.最常见的比较级句式是由连词than引导比较的对象, G^#>HE|  
如:It takes less time to go there by air than by train. "q+Z*   
  She possesses more books than I do. `Ucj_6&Tqs  
  He is more intelligent than I expected. uJ -$i   
than可视为比较级的标志词,在填空题中, h!%y,4IBR  
空后含有than的, 通常空格处需要填比较级, Z>bNU  
空格前含有比较级的,通常空格处需要填than引导的从句。 \ *[Ht!y  
例题: ~M{/cv  
(1) &RARK8 ^  
Maine has ---- weather than most of the other states in the continental United States. Q|h$D~  
(A) coolest bUm %#a  
(B) the coolest v0oVbHO5<  
(C) cooler 6,q_ M(;c  
(D) the cooler .,xyE--;d  
答案:A )5~T%_  
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 #<b\BqYG  
(2) SDO:Gma  
Pennsylvania has the most institutions of higher learning than any other state has. 6[k<&;  
           A   B              C     D %K|f,w=m  
答案:A n4S `k%CI  
应改为:more SR?mSpq5  
解释:标志词than表明此句应用比较级,而不是最高级 GkI'.  
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: C{85#`z`  
情况1: 用指示代词that, those来代替省略的部分, zY:3*DiM  
如:The population of China is much larger than that of Great Britain. 6_KvS  
   (that 指代the population) k-=lt \?  
  His designs won more acclaim than those of his fellow colleagues. y*+8Z&i.:  
   (those 指代 designs) V sl,u  
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) s=(q#Z  
如:The actors usually capture greater attention than do the playwrights who may HP]5"ziA  
    probably contribute more to the success of a play. -_t4A *  
例题: Jk>vn+q8P^  
Mammals have a larger, more well-developed brain ---- other animals. yPtE5"(o  
(A) than do 56<UxIa~  
(B) that are having M{G}-QK_.  
(C) which have 2sIt~ Gn  
(D) that do bl a`B=r  
答案:A r+C4<-dT  
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 7ihcjyXB  
xtP:Q9!N  
考点二 (not) so /as…as Vq]ixag2^  
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, 6?[P^{GpH  
如:It is as good as it looks. Z[*unIk  
  The boss is not so bad-tempered as you have described. o FP8s[B  
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。 2YZ>nqy  
例题: )S+fc=  
(1) N`efLOMl]  
The best way to control rats is by seeing that they have as ----. $L0sBW&  
(A) possibly little nourishment ?HPAX  
(B) nourishment possibly little [nig^8  
(C) little as possible nourishment `OMX 9i  
(D) little nourishment as possible T>% 5<P  
答案:D LJ <pE;`d  
解释:空格处需要动词have的宾语,同时包含as…as句式,A、B都缺少与as搭配的结构,C语序有误,均可排除。D中as…as possible, 为固定用法, 意为“尽可能”. 0ex.~S_Oj4  
(2) %f &Y=  
There is evidence that prehistoric humans used fire ---- 400,000 B.C. xSD*e 0  
(A) so early ~) _N h  
(B) the earliest L q>lj`>  
(C) as early as n?cC]k;P~  
(D) so early that eg/itty  
答案:C v}u]tl$,  
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 rwXpB<@l@  
/5Qh*.(S  
考点三 the same…as ZT!8h$SE:  
此句式也常用来表示“和……一样”,the same和as既可连用,也可分开使用, -(?/95 Y  
如:She looks just the same as before. %Ve@DF8G  
  I got the same feeling as you did. `.pEI q^  
改错题中常将此句式误用为the same…like /than, 要练就一双火眼金睛将其识别出来 #d$z W4ur2  
例题: ^L $`)Ja  
(1) <}[ !k<  
Meadowlarks are about the same size than robins, but they have heavier bodies, QD!NV*  
         A       B          C Rs"=o>Qu  
shorter tails, and longer bills. + GQ{{B  
            D id9QfJ9t  
答案:B u]NsCHKlT  
应改为:as. W8^A{l4  
解释:the same as是固定搭配, 表示“与...一样” 8[J%TWq%9  
(2) *Lrrl

  A                 B    #Q7:Mu+  
perishable goods in Toronto like in New York City. 3G4WKg.^  
   C          D K>.}>)0  
答案:D agwbjkU/  
应改为:as cwvJH&%0  
解释:与the same相搭配的只有as, like不行 IQ\!wWKmY  
."dT6uE  
考点四 the more…,the more… S>x@9$( ym  
此句式常表示“越……越……”,more在此处泛指比较级,此句式的特点是前后两句以逗号隔开,句子结构平行,而且谓语动词一致时,为避免重复常进行省略, Bv~^keuj3t  
如:The more she slept, the less comfortable she felt. ru`7iqcz  
  The greater the size, the easier it is for you to spot. ( ww4(  
填空题中常需填入两个分句之一,因此看到the more结构,要注意选与其结构相近的另一半the more句式 -'miM ~kG[  
例题: gnN> Rl 5_  
(1) c$[2tZ  
The greater the population there is in a locality, ----for water, transportation, and disposal of refuse. I52nQCXi  
(A) the greater the need there is ?& :N|cltD  
(B) greater need *<cRQfA1  
(C) is there great need Cw:|(`9  
(D) the great need :K~@JlJd  
答案:A yj_/:eX  
解释:这是典型的 “the more…, Na oOgZ?  
qdk!.A{   
a+z >pV|  
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. hO> q|+mC  
(2) (BH<\&yHE  
The less the surface of the ground yields to the weight of the body of a runner, ---- to the body. Oq<3&*  
(A) the stress it is greater .=}\yYGe   
(B) greater is the stress Jityb}Z"  
(C) greater stress is W="pu5q $5  
(D) the greater the stress _^{RtP#=  
答案:D %Jl6e}!  
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 qYe`</  
i88 5T '  
考点五 no longer /not…any longer ? -&k?I  
no longer /not…any longer和no more/not…any more都表示“不再……”, Fi+ DG?zu  
如:He no longer smokes. / He doesn't smoke any longer. h;E.y   
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。 ok,O/|E}?  
例题: ]c_lNHssmq  
(1)  3k6Dbz

    C                           D , =*^XlO=c  
答案:A _,F\%}  
应改为:no longer. x=K'Jj  
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
