高分语法讲解2

考点四 名词(词组)作定语 ]N#%exBVo  
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 {zmh0c; |  
这样的词语有:word order(词序), taxi driver(出租车司机)等 3{/Y&/\"'^  
例题: qTV;L-  
(1) kaUEv\T   
Situated in the heart of a grain-farming and livestock-raising region, Abilene, Kansas, *? <ygzX  
 A                       B x<lY&KQ0  
is a prosperous trading and distribute center. -&UP[Mq  
   C         D R32A2Ml  
答案: D -w3KBlo  
应改为: distribution/ distributing. Zk .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 3;t{V$  
(2) w15Qqh lK  
Acrylic paint enables artists to experiment with many colors effects. $sa5aUg }  
   A  B      C         D 3Gyw^_{J  
答案: D  A&8{0  
应改为: color R8(Bt73  
解释: 此处名词color作effects的定语无需用复数, 意为色彩效果 `COnb@uD  
6upCL:A~r  
FQp@/H^  
第二章 形容词 $6Az\Iu *  
"u=U@1 ^  
形容词即strong, attractive等描述性的词汇,在句中主要作定语修饰名词,同时还可作表语、宾语补足语等成分 Mb +  
tY>_ +)oi  
第一节 形容词修饰名词 -Rcl(Q}LZ  
;"T,3JQPn6  
形容词最主要的功能就是修饰名词,如:modern art, electric current, great responsibility;这一考点在TOEFL改错题占有相当的比例,几乎每套题都包含一道以上的题目考形容词修饰名词,主要形式是将本应该使用形容词的位置误用为名词、副词等 T:?01 ?m  
例题: G1z0q3< B  
(1) _ W +  
The human body relies on certainty nutrients for its survival. {EL J!o[  
       A  B   C          D g71|t7Q  
答案:C [/'=M h  
应改为:certain. *v6 j7<H  
解释:certainty是名词, 意为确定性, 不能修饰名词, 改为形容词certain, 表示某些 z pV+W-j]  
(2) xmp^`^v*  
Textile art is known for both its tactile and vision qualities. eJ2$DgB}t  
  A       B         C   D SGK=WLGM8  
答案:C -!JnyD   
应改为:visual. c*:H6(u  
解释:vision是名词, 不能修饰名词qualities, 要用它的形容词 ]%I}hj J  
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: =(%+S<}  
The man was awake. KH_~DZU*5  
There was an awake man. (此句错误, awake不能做定语) \ &#pJB BG  
这类形容词包括: alone, afraid, alike, alert, aware, alive, ashamed, content, unable pjaDtNb  
例题: qQ=\R1l  
(1) QT[yw6Z  
Many television newscasters make the public an eyewitness to the news by means ,- FC  
     A                 B        C 6 OLp x)fG  
of on-the-spot, alive reports. EKTn$k=  
       D yL.Z{wd  
答案: D c(5r  
应改为:live (adj. 现场的, 实况转播的) i{.%4tA4  
解释:alive不能做定语, 只能做表语,所以应该改为live reports (现场报道) ~wl 4  
(2) %M KZ':m  
Alike ethnographers, ethnohistorians make systematic observations, but they also Kp.d#W_TX  
 A              B               C 1GA$nFBVC  
gather data from documentary and oral sources. kEr; p{5  
                 D SuuLB6{u3  
答案: A ` 0}z ;&:  
应改为:like ICxj$b  
解释:alike不能做定语, 只能做表语; alike/like 是TOEFL改错中常考的考点 r'5~4'o$  
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. /rQ[Ik$|  
如:a room bare of furniture, the form dependent of the contents等, -YD+x PD  
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, $~s|%>@  
一般来说:这个排序的规则是: |2'u@<(Z/  
冠词(a, an, the)/所有格(my, your等)/指示代词(this, that等) + 数量形容词 + 描述性形容词 + 名词 'Bc{N^  
如: two young American students g(`m#&P>G  
    my three red pencils qY^@^)b[  
第二节 比较级 Utv#E.VI  
英文中形容词在进行比较时需变为比较级,主要有两种形式: ecg>_%.>  
在词尾加-er (单音节形容词),如:fast-faster, large-larger, busy-busier, big-bigger等; S( nZ]QEG  
或在词前加more (多音节形容词),如:more useful, more complex等 BXx0Z %e.3  
少数词比较级形式特殊,如:good(well)-better, bad(ill)-worse, many(much)-more, little-less, far-farther(更远的)/further(更进一步的), 9+!1jTGSkf  
45+w)Vf!  
U|2*.''+Q  
考点一 含有标志词than I]dt1iXu_{  
1.最常见的比较级句式是由连词than引导比较的对象, G,]%dZH e  
如:It takes less time to go there by air than by train. Rfuq(DwD6  
  She possesses more books than I do. )4@La&  
  He is more intelligent than I expected. iJH;OV;P  
than可视为比较级的标志词,在填空题中, vsDR@Y}k  
空后含有than的, 通常空格处需要填比较级, <XAW-m9SC  
空格前含有比较级的,通常空格处需要填than引导的从句。 bm Hl\?  
例题: RXZ}aX[h  
(1) \8 ~`NF  
Maine has ---- weather than most of the other states in the continental United States. T+9#&  
(A) coolest [LcHO] _^M  
(B) the coolest L4wKG&  
(C) cooler qwz_.=5E6  
(D) the cooler -N4km5  
答案:A K$K 6,54y  
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 e jID5NqG  
(2) a*fUMhIi  
Pennsylvania has the most institutions of higher learning than any other state has. B"9/+Yj  
           A   B              C     D bOKgR{i  
答案:A :^Ouv1!e1  
应改为:more e?"XM Y  
解释:标志词than表明此句应用比较级,而不是最高级 G"~%[ k  
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: R"0fZENTG  
情况1: 用指示代词that, those来代替省略的部分, Oy,`tG0  
如:The population of China is much larger than that of Great Britain. 'aFjyY?%  
   (that 指代the population) @\_l%/z{  
  His designs won more acclaim than those of his fellow colleagues. 2d`:lk%\  
   (those 指代 designs) pjh o#yP  
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) W%)uKQha  
如:The actors usually capture greater attention than do the playwrights who may 8LH"j(H  
    probably contribute more to the success of a play. iHp@R-g  
例题: svBT~P0x  
Mammals have a larger, more well-developed brain ---- other animals. T==(Pw7R7  
(A) than do @n- [bN  
(B) that are having =h#3D?b0n  
(C) which have lQnl6j  
(D) that do -@wnQ?  
答案:A iyRB}[y  
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 oZY2K3J)  
^YpA@`n  
考点二 (not) so /as…as cP4K9:k  
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, -]uN16\ F  
如:It is as good as it looks. z&"-%l.b@}  
  The boss is not so bad-tempered as you have described. 7d7"^M  
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。 N<xf=a+j  
例题: 6+:Tv2  
(1) :OF:(,J  
The best way to control rats is by seeing that they have as ----. ; U)a)l'y  
(A) possibly little nourishment 3E!#?N|v  
(B) nourishment possibly little j:yQP# U  
(C) little as possible nourishment ; FO1b*  
(D) little nourishment as possible ,C#Mf@b  
答案:D {|}tp<:2  
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”. }HM8VAH  
(2) MI |51&m

(A) so early ZWC-<QO"<  
(B) the earliest X7I"WC1ncz  
(C) as early as VQm)32'  
(D) so early that *0 ;DCUv  
答案:C $J/Z~ (=JT  
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 dQ=mg#(  
Lx-ofN\  
考点三 the same…as \#(cI  
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, *t;'I -1w^  
如:She looks just the same as before. Gs*FbrY  
  I got the same feeling as you did. H61 ,pr>  
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 UTEUVcJ\  
例题: yZ[H&>  
(1) ta>:iQ a  
Meadowlarks are about the same size than robins, but they have heavier bodies, (+<SR5,/3  
         A       B          C }5H3DavW  
shorter tails, and longer bills. })Og sBk  
            D Y{X79Rd   
答案:B tT}*%A  
应改为:as. N|c;Qzl  
解释:the same as是固定搭配, 表示“与...一样” m~%\f8w-x  
(2) g{@q  
Due to sophisticated transportation networks, people can now buy the same types of I_mnXd;n  
  A                 B    ^Bw2y&nN  
perishable goods in Toronto like in New York City. ,K Ebnk|i  
   C          D B./Lp_QK  
答案:D +K4d(!Sb  
应改为:as  .g.v  
解释:与the same相搭配的只有as, like不行 G>{ Bij44  
ANEW^\  
考点四 the more…,the more… 3]BK*OqJ  
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, gF;i3OJg  
如:The more she slept, the less comfortable she felt. h#9X0u7j  
  The greater the size, the easier it is for you to spot. q/,>UtRr  
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 T]\_[e :'  
例题: ^ZX71-  
(1) ec/1Z8}p  
The greater the population there is in a locality, ----for water, transportation, and disposal of refuse. (]0JI1 d  
(A) the greater the need there is "ewSh<t  
(B) greater need b f.__3{  
(C) is there great need H%`Ja('"p  
(D) the great need V dp wZ  
答案:A Md_S};!QN6  
解释:这是典型的 “the more…, -@{5 u d  
wP.b2X_V  
ca/AScL  
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. xMNUy B{?  
(2) ,h,DB=!K<  
The less the surface of the ground yields to the weight of the body of a runner, ---- to the body. (LzVWz m  
(A) the stress it is greater <eP`Lu"  
(B) greater is the stress sJ[I<  
(C) greater stress is o.IJ4'}aN  
(D) the greater the stress (27bNKr  
答案:D 7}>7@W8  
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 T$[50~  
9<BC6M_/  
考点五 no longer /not…any longer 8."B  
no longer /not…any longer和no more/not…any more都表示“不再……”, /<7'[x<  
如:He no longer smokes. / He doesn't smoke any longer. ]t$wK  
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。 .YYfba#{  
例题: w1tWyKq  
(1) IiW*'0H:/  
  Although it is any longer the big business that it was in the forties, radio vz'/]E  
          A           B      yOHVL~F

    C                           D ejs_ ?   
答案:A #Bu W  
应改为:no longer. )b AOA  
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
