高分语法讲解2

考点四 名词(词组)作定语 SHdL /1~t  
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 %l9$a`&  
这样的词语有:word order(词序), taxi driver(出租车司机)等 2P~)I)3V  
例题: O+ .*lo  
(1) H30OUrD  
Situated in the heart of a grain-farming and livestock-raising region, Abilene, Kansas, [ x>  
 A                       B 6* r cR]  
is a prosperous trading and distribute center. -Wo15O"  
   C         D *{/@uO  
答案: D ]A:( L9  
应改为: distribution/ distributing. rFd@mO  
解释: 动词distribute不能修饰名词center,可改用名词或分词, 但此题中名词distribution作定语更符合英文习惯 K; kM_%9u  
(2) Rl@$xP  
Acrylic paint enables artists to experiment with many colors effects. lmFA&s"m  
   A  B      C         D wly>H]i'  
答案: D QUP|FIpZ  
应改为: color ;L6Xs_L~  
解释: 此处名词color作effects的定语无需用复数, 意为色彩效果 .hz2&9Ow  
QrS$P09=\  
YOw?'+8  
第二章 形容词 k,_i#9 X  
HF4Lqh'oco  
形容词即strong, attractive等描述性的词汇,在句中主要作定语修饰名词,同时还可作表语、宾语补足语等成分 jH0Bo;  
@36S}5Oa  
第一节 形容词修饰名词 /2w@ K_Px6  
w6U @tW  
形容词最主要的功能就是修饰名词,如:modern art, electric current, great responsibility;这一考点在TOEFL改错题占有相当的比例,几乎每套题都包含一道以上的题目考形容词修饰名词,主要形式是将本应该使用形容词的位置误用为名词、副词等 B)a@fmp"a  
例题: _;G=G5r  
(1) 5; f\0<-  
The human body relies on certainty nutrients for its survival. -3k;u  
       A  B   C          D *gSO&O=  
答案:C okDJ(AIV+  
应改为:certain. 41 'EA \V  
解释:certainty是名词, 意为确定性, 不能修饰名词, 改为形容词certain, 表示某些 5&(3A|P2  
(2) AfE%a-;:  
Textile art is known for both its tactile and vision qualities. B(Y.`L? %E  
  A       B         C   D ^srs$ w]  
答案:C '>]&rb09|  
应改为:visual. }} #be  
解释:vision是名词, 不能修饰名词qualities, 要用它的形容词 ;+9(;  
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: 3{q[q# "  
The man was awake. _#(s2.h~J  
There was an awake man. (此句错误, awake不能做定语) a 8-;   
这类形容词包括: alone, afraid, alike, alert, aware, alive, ashamed, content, unable 9<Ag1 l  
例题: Nx B+?  
(1) /=ACdJ  
Many television newscasters make the public an eyewitness to the news by means 9 P~d:'Ib  
     A                 B        C D+hB[*7Fs  
of on-the-spot, alive reports. khS/'b  
       D LV\ieM  
答案: D A?' H[2]w"  
应改为:live (adj. 现场的, 实况转播的) @Q3, bj  
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) } bCK  
(2) .xo_}Vw  
Alike ethnographers, ethnohistorians make systematic observations, but they also !c."   
 A              B               C }M?|,N6  
gather data from documentary and oral sources. _y"a2M  
                 D ]p\u$VY9  
答案: A ysl8LK   
应改为:like MyqiBGTb  
解释:alike不能做定语, 只能做表语; alike/like 是TOEFL改错中常考的考点 mDlCt_h  
注意2:形容词词组修饰名词时要发生后置现象, 避免产生头重脚轻的感觉. 9D%qXU  
如:a room bare of furniture, the form dependent of the contents等, 7\f{'KL  
注意3:形容词修饰名词的语序也是TOEFL考点之一。 当多个形容词(甚至包括指示代词, 冠词和所有格)并列放置于名词之前时, 它们之间就存在着谁排在前面, 谁排在后面的问题, |FjBKj  
一般来说:这个排序的规则是: ,5 =kDw2  
冠词(a, an, the)/所有格(my, your等)/指示代词(this, that等) + 数量形容词 + 描述性形容词 + 名词 % kJh6J  
如: two young American students i'Wcf1I-=  
    my three red pencils LH,]vuXh  
第二节 比较级 p8$\uo9YQ  
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: iF8@9m  
在词尾加-er (单音节形容词),如:fast-faster, large-larger, busy-busier, big-bigger等; f!mE1,eBEe  
或在词前加more (多音节形容词),如:more useful, more complex等 XNKtL]U}$  
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), HE@-uh  
avmcGyL  
/i> ?i@O-  
考点一 含有标志词than :a=ro2NH  
1.最常见的比较级句式是由连词than引导比较的对象, ;,mBT[_ZO  
如:It takes less time to go there by air than by train. 4P`PmQ=GQh  
  She possesses more books than I do. <=$rU232}  
  He is more intelligent than I expected. =.VepX|?D  
than可视为比较级的标志词,在填空题中, 3L?WTS6(u  
空后含有than的, 通常空格处需要填比较级, CQj/e+eE4  
空格前含有比较级的,通常空格处需要填than引导的从句。 F19;RaP+  
例题: l}dj{ s  
(1) RA#\x.  
Maine has ---- weather than most of the other states in the continental United States. -6AOK<kfI  
(A) coolest & 8ccrw  
(B) the coolest +dDJes!]  
(C) cooler H<v c\r  
(D) the cooler ]lymY _ >  
答案:A }P05eI  
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/u'bDq  
(2) 5}<.1ab3V  
Pennsylvania has the most institutions of higher learning than any other state has. nrxjN(9V%+  
           A   B              C     D N;e;4,_ n  
答案:A s 4MNVT  
应改为:more hdo+Qezu:  
解释:标志词than表明此句应用比较级,而不是最高级 \a{Aa  
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: i)A`Vpn  
情况1: 用指示代词that, those来代替省略的部分, HY*l4QK  
如:The population of China is much larger than that of Great Britain. ~5-~q0Ge  
   (that 指代the population) $xKg }cO  
  His designs won more acclaim than those of his fellow colleagues. trID#DT~  
   (those 指代 designs) P58\+9d_  
情况2: 在省略的过程中,若than之后从句的谓语部分相同, 比较的是主语部分, 那么谓语部分通常用助动词do来代替, 并且习惯上将从句主语和助动词倒装 (do + 主语) =g{_^^n  
如:The actors usually capture greater attention than do the playwrights who may S/#) :,YS  
    probably contribute more to the success of a play. f]@[4<Ny  
例题: ?K= gg<  
Mammals have a larger, more well-developed brain ---- other animals. `D&#U'wB   
(A) than do z6GL,wo#  
(B) that are having 5#9`ROT9  
(C) which have &4ug3  
(D) that do ?M*C*/R  
答案:A z/ c'Z#w%  
解释:空格前出现了形容词比较级,空格后是比较对象,应由than连接,选项中只有A符合条件,其中由助动词do引起了一个小倒装 {,nd_3"Vq  
g7E`;&f  
考点二 (not) so /as…as mvW^P`nB  
比较级特殊句式(not)so/as…as 表示“如同……一样、不如……”等意思,其结构和than句式相仿,但as…as之间的形容词必须用原形,而且as…as必须搭配使用, +oxqS&$L  
如:It is as good as it looks. HQ-N!pf9  
  The boss is not so bad-tempered as you have described. ]ly)z[is"]  
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。 %j 9vX$Hj  
例题: QrrZF.  
(1) (+]Ig> t  
The best way to control rats is by seeing that they have as ----. f"} 0j|Gg  
(A) possibly little nourishment X:zyzEhS  
(B) nourishment possibly little g:@Cg.q8  
(C) little as possible nourishment .q'FSEkMJ  
(D) little nourishment as possible .PA ?N{z  
答案:D $AL|d[[T[  
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”. N8/Au= De_  
(2) D%5 {A=  
There is evidence that prehistoric humans used fire ---- 400,000 B.C. 5BGv^Qb_2  
(A) so early /M{)k_V  
(B) the earliest &`\kb2uep  
(C) as early as e-T9HM&%P  
(D) so early that r(/P||`l  
答案:C pqNoL* H  
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  # 8-P  
 (t]R#2{  
考点三 the same…as u0$5Fd&X  
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, a7 '\*  
如:She looks just the same as before. k%bTs+] *  
  I got the same feeling as you did. vr]dRStr  
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 EZu  
例题: s $=B~l  
(1) v*T@ <]f3j  
Meadowlarks are about the same size than robins, but they have heavier bodies, h^3Vd K,  
         A       B          C T=)L5Vuq<  
shorter tails, and longer bills. KTS7)2ci  
            D s t3]Yy  
答案:B N'1[t  
应改为:as. Y_ u7 0@`  
解释:the same as是固定搭配, 表示“与...一样” :O2v0Kx  
(2) @%okaj#IO  
Due to sophisticated transportation networks, people can now buy the same types of 8C4@V[sm`  
  A                 B    !-Tmu  
perishable goods in Toronto like in New York City. Z_TbM^N  
   C          D YJ;a{)e  
答案:D Ql!6I(  
应改为:as ,@j& q  
解释:与the same相搭配的只有as, like不行 S&g -  
n ;fTx  
考点四 the more…,the more… &qj&WfrB,  
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, L&F\"q9q71  
如:The more she slept, the less comfortable she felt. `[R:L.H1  
  The greater the size, the easier it is for you to spot. Xv;ZAa  
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 REe%>|   
例题:  7qdl,z  
(1) F_ lj>;}a5  
The greater the population there is in a locality, ----for water, transportation, and disposal of refuse. tw^.(m5d  
(A) the greater the need there is "Kf~`0P  
(B) greater need +/ d8d  
(C) is there great need yvnrZ&x :  
(D) the great need <UHf7:0V  
答案:A $+yQ48Wq  
解释:这是典型的 “the more…, 9n2%7dLQ*  
5Ddyb%  
I.0Usa"z  
the more…” 句式, 意为 “越…, 越…” 其逗号前后两部分结构要平行, 而且后一句可以不倒装, A 完全符合要求. C D 都缺少此固定句式所要求的第二个比较级; B 少定冠词the. 此句亦可改写为: If there is greater population in a locality, there will be greater need for water, transportation, and disposal of refuse. .ceU @^  
(2) LGue=Hkp  
The less the surface of the ground yields to the weight of the body of a runner, ---- to the body. <\Dl#DH  
(A) the stress it is greater 04LVa|Y@U  
(B) greater is the stress IOsDVIXL\  
(C) greater stress is ."g5+xX  
(D) the greater the stress 8&iI+\lCy  
答案:D Yl3PZ*#@ Q  
解释:此句涉及比较级的特殊句式the more..., the more..., 此句式要求前后结构平行,当谓语一致时,后面的可省略,符合要求的只有D mLdyt-1  
1T^L) %&p_  
考点五 no longer /not…any longer G~j<I/)"  
no longer /not…any longer和no more/not…any more都表示“不再……”, lAt1Mq} ?P  
如:He no longer smokes. / He doesn't smoke any longer. !q1^X% a  
注意no longer /not…any longer不要混用,no more /not…any more同理,这一句式在改错题中出现。 *y$ry]   
例题: \X p"I5  
(1) y.NArN|%

    C                           D sm S0Rk  
答案:A jv^ L~<u  
应改为:no longer. )eyxAg  
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
