高分语法讲解2

考点四 名词(词组)作定语 %D3Asw/5a  
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 fR]KXfZ  
这样的词语有:word order(词序), taxi driver(出租车司机)等 sGx3O i   
例题: >qZl s'  
(1) 06z+xxCo  
Situated in the heart of a grain-farming and livestock-raising region, Abilene, Kansas, 4UHviuOo8  
 A                       B z9E*1B+  
is a prosperous trading and distribute center. <m~{60{  
   C         D u82(`+B  
答案: D Q CO,f  
应改为: distribution/ distributing. w?P ex]i{  
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 mbns%%GJU  
(2) 4v` G/w  
Acrylic paint enables artists to experiment with many colors effects. <H$!OPV  
   A  B      C         D W#2} EX  
答案: D aYM~Ub:x{  
应改为: color 7CH.BY  
解释: 此处名词color作effects的定语无需用复数, 意为色彩效果 Bru];%Qg%  
b,X+*hRt  
7A h   
第二章 形容词 xQl}~G]!  
8tVSa i8[  
形容词即strong, attractive等描述性的词汇,在句中主要作定语修饰名词,同时还可作表语、宾语补足语等成分 iH~A7e62OZ  
}I1j#d0.  
第一节 形容词修饰名词 =R"LB}>h}  
tEt46]{  
形容词最主要的功能就是修饰名词,如:modern art, electric current, great responsibility;这一考点在TOEFL改错题占有相当的比例,几乎每套题都包含一道以上的题目考形容词修饰名词,主要形式是将本应该使用形容词的位置误用为名词、副词等 P-<1vfThH  
例题: Ow(aRWUZD_  
(1) C_JO:$\rE  
The human body relies on certainty nutrients for its survival. vK`HgRQ(C  
       A  B   C          D gAVD-]`  
答案:C O<#8R\v  
应改为:certain. I 1rB,%p  
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 0+u >"7T  
(2) R+_!FnOJ  
Textile art is known for both its tactile and vision qualities. e7bMK<:r  
  A       B         C   D ' oH3|  
答案:C A}}dc:$C  
应改为:visual. / DP0K @%  
解释:vision是名词, 不能修饰名词qualities, 要用它的形容词 gf?N(,  
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: EJRkFn8XG'  
The man was awake. oz]&=>$1I  
There was an awake man. (此句错误, awake不能做定语) tCm]1ZgRW  
这类形容词包括: alone, afraid, alike, alert, aware, alive, ashamed, content, unable 9|[uie  
例题: _!!Fg%a5"R  
(1) e6bh,BwgQq  
Many television newscasters make the public an eyewitness to the news by means \WbQS#Z9  
     A                 B        C Fn iht<  
of on-the-spot, alive reports. m OE!`fd  
       D sOiM/} O]  
答案: D +95v=[t#Ut  
应改为:live (adj. 现场的, 实况转播的) 5pC}ZgEa<  
解释:alive不能做定语, 只能做表语,所以应该改为live reports (现场报道) 1e7I2g  
(2) BFg&@7.X  
Alike ethnographers, ethnohistorians make systematic observations, but they also #HW< @E  
 A              B               C L &hw- .Q  
gather data from documentary and oral sources. s$? LMfT  
                 D hvQXYo>TZx  
答案: A ip l,{  
应改为:like yTh%[k  
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 "a}fwg9Y  
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. )7[#Ti  
如:a room bare of furniture, the form dependent of the contents等, erbk (  
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, p!=O>b_f  
一般来说:这个排序的规则是: D4{KU%Xp&  
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 +4 Pes  
如: two young American students #^Pab^Y3r-  
    my three red pencils iU37LODa2T  
第二节 比较级 deV nAu =  
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: l'aCpzf  
在词尾加-er (单音节形容词),如:fast-faster, large-larger, busy-busier, big-bigger等; 4#7*B yvf  
或在词前加more (多音节形容词),如:more useful, more complex等 "}`)s_rt  
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), EwU)(UK  
;b~\ [  
'6WS<@%}  
考点一 含有标志词than no L9@It0  
1.最常见的比较级句式是由连词than引导比较的对象, {>9ED.t  
如:It takes less time to go there by air than by train. #0Y_!'j  
  She possesses more books than I do. kltW  
  He is more intelligent than I expected. ' h< (  
than可视为比较级的标志词,在填空题中, V+y"L>K  
空后含有than的, 通常空格处需要填比较级, ^V#,iO9.-  
空格前含有比较级的,通常空格处需要填than引导的从句。 /e?0Iv" 8>  
例题:  ~IjID  
(1) )7NI5x^$  
Maine has ---- weather than most of the other states in the continental United States. F.5fasdX'  
(A) coolest FE&:?  
(B) the coolest wW1\{<hgr  
(C) cooler <Nqbp  
(D) the cooler Y$\|rD^f  
答案:A X(MS!RV  
解释:标志词than意味着应用比较级,A, B可先排除;D多the; 只有A正确 ],S {?!'1  
(2)  =g M@[2  
Pennsylvania has the most institutions of higher learning than any other state has. ?z&%VU"  
           A   B              C     D _W_< bI34  
答案:A Cp" 7R &s  
应改为:more OM&GypP6&  
解释:标志词than表明此句应用比较级,而不是最高级 Y.]$T8  
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: 9g5h~ Ma  
情况1: 用指示代词that, those来代替省略的部分, #o4tG  
如:The population of China is much larger than that of Great Britain. >>$`]]7  
   (that 指代the population) W Eif&<Y  
  His designs won more acclaim than those of his fellow colleagues. -|uox j>  
   (those 指代 designs) R=LiB+p  
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) jd-]q2fQ|  
如:The actors usually capture greater attention than do the playwrights who may 8mKp PwG0  
    probably contribute more to the success of a play. D4[t^G;J  
例题: }0Ns&6)xG  
Mammals have a larger, more well-developed brain ---- other animals. 0~^RHb.NA8  
(A) than do G#7(6:=;,`  
(B) that are having 7 s5(eQI  
(C) which have q -8G  
(D) that do C\GP}:[T3  
答案:A ([dd)QU  
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 q_h (D/g  
A,cXN1V  
考点二 (not) so /as…as j/d}B_2  
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, HT.*r6Y>g  
如:It is as good as it looks. 7}UG&t{  
  The boss is not so bad-tempered as you have described. 1d<Uwb>  
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。 *b. >  
例题: '6 F-%  
(1) WqCC4R,-  
The best way to control rats is by seeing that they have as ----. 0yI1r7yNB+  
(A) possibly little nourishment tO3R&"{  
(B) nourishment possibly little _NsEeKU  
(C) little as possible nourishment - |g"q|  
(D) little nourishment as possible f|~{j(.v  
答案:D rQVX^  
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”. d}h{#va*  
(2) '|zrzU=  
There is evidence that prehistoric humans used fire ---- 400,000 B.C. *{DTxEy  
(A) so early zl|z4j'Irc  
(B) the earliest TQF+aP8[L  
(C) as early as qJrT  
(D) so early that R}M ;, G  
答案:C E5bVCAz  
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 &3[oM)-V  
AAevN3a#nI  
考点三 the same…as g 4[Vgmh J  
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, <h7cQ  
如:She looks just the same as before. YB5"i9T2  
  I got the same feeling as you did. _s=H|#l  
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 'BjTo*TB]Z  
例题: XVYFyza;  
(1) W&?Qs=@  
Meadowlarks are about the same size than robins, but they have heavier bodies,   EO&Q  
         A       B          C *|fF;-#v  
shorter tails, and longer bills. Rm} ym9  
            D N T`S)P*?  
答案:B hxO}'`:  
应改为:as.  x]+PWk  
解释:the same as是固定搭配, 表示“与...一样” s<9g3Gh  
(2) AI-*5[w#A  
Due to sophisticated transportation networks, people can now buy the same types of ysW})#7X  
  A                 B    %;,fI'M  
perishable goods in Toronto like in New York City. z%82Vt!a5  
   C          D i})s4%a  
答案:D L8VOiK=,  
应改为:as v`HE R6  
解释:与the same相搭配的只有as, like不行 ju"z  
h: ' |)O  
考点四 the more…,the more… g4IF~\QRVi  
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, e8F]m`{_"  
如:The more she slept, the less comfortable she felt. s^wm2/Yw  
  The greater the size, the easier it is for you to spot. 8>&@"j  
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 va6Fp2n<1*  
例题: EuK}L[Kl  
(1) _%w680b'  
The greater the population there is in a locality, ----for water, transportation, and disposal of refuse. i9;  
(A) the greater the need there is x'GB#svi  
(B) greater need T8XrmR&?PX  
(C) is there great need tn]nl!_@  
(D) the great need 7'G;ijx  
答案:A ]juPm8eF  
解释:这是典型的 “the more…, Fc~G*Gz~Z|  
Ar`+x5  
0HzqU31%l@  
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. (8d uV  
(2) k9Pvh,_wp

(B) greater is the stress tW\yt~q,  
(C) greater stress is  YKyno?m  
(D) the greater the stress o`bch? ]  
答案:D d>QFmsh-  
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 ^P) f]GQx  
W__ArV2Z_  
考点五 no longer /not…any longer 0dch OUj  
no longer /not…any longer和no more/not…any more都表示“不再……”, >Bt82ibN  
如:He no longer smokes. / He doesn't smoke any longer.  NkZG   
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。 ]G/m,Zv*:  
例题: a=z] tTs4  
(1) >B BV/C'9  
  Although it is any longer the big business that it was in the forties, radio g`XngRb|j

    C                           D cD !,ZL  
答案:A As:O|!F  
应改为:no longer. w,UE0i9I  
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
