该错题常考要点

该错题常考要点 ?<!|  
一、代词 w )f#V s  
代词中主要讲解六个问题 O.? JmE  
(一) 掌握代词的几种格 _BufO7 `.  
  主格、宾格、所有格 )~>YH*g  
  名词前面用代词来修饰,只能用所有格(my books) x}4q {P5$  
.-zom~N-?  
(二) 反身代词 hrk r'3lv  
当主语和宾语表示同一事物时,宾语使用反身代词。 c<~H(k'+c  
  He killed himself. (他自杀了) zLQx%Yg!  
  He killed him. (他杀了他) w0. u\  
WJi]t93  
例:Researchers at the University of Colorado are investigating  UKGPtKE<  
    A                 B    h[ ZN+M  
  a series of indicators that could help jXJyc'm7  
             C      G@0& 8  
  themselves to predict earthquakes. BT$_@%ea&  
    D TeQV?ZQ#}  
分析:D错,应改为them。如果用反身代词themselves,指代对象是从句主语that(即名词indicators),这显然是错误的。从句意来看,help的宾语应该是主句主语researchers,故应用代词宾格而不是反身代词。注意C并没有错,情态动词could 比can语气弱,表示较小的可能性。 :RYTL'hes  
Indicator为征兆,这些征兆帮助他们来预言地震。主语是征兆,后面指研究者,不是同一个事物 }V>T M{  
~DWl s.  
(三) 代词的单复数,代词的性别  ]~-r} `]  
在考试中如果代词打横线,代词错误的概率是非常高的,因此代词打横线,应该先看代词有没有错。 !-bB559Nv  
`cO:<^%  
例:The continental divide refers to an imaginary line in the North American Rockies AA_%<zK  
  that divides the waters flowing into the Atlantic Ocean from it flowing into the \e_O4  
     A   B      C          D ICCc./l|  
  Pacific. zs;JJk^  
?2a$*(  
分析:D错,应改为those。D指代复数名词waters, it是单数,显然是错误的,根据习惯故改为those。注意waters一词并没有错,它指江湖河海中的大片水域,可用复数形式。 u2I Cl  
6@f-Glwg  
Water作为水是不可数名词,waters表示水域,通常使用复数形式,作主语谓语动词用复数。 1M-pr 8:6s  
Work作为工作是不可数名词,work作为作品,可数不可数都可以,例如: G3]4A&h9v~  
  Many of his works= much of his work, work都表示作品 zDp2g)  
^.tg7%dJ  
例:In 1920 the presidential candidate Warren Harding coined }G=M2V<L  
                       A   TC. ,V_  
  the word“normalcy”to express social and [lAp62i5  
             B 0YzpZW"+  
   economic conditions they promised the nation. +p^u^a  
   C       D "b[5]Y{ U  
分析:D错,应改为he。动作promised是由Warren Harding发出来的,故用第三人称单数he来指代。 ;jPXs  
AGno6g  
例:Many critics believe that Amy Lwell' s most important Y7nvHU|+o  
        A     .pq%?&  
  work is not poetry, but his biography, John \ jA~9  
   B        C      !BI;C(,RL  
  Keats, published the year of her death.  yVc(`,tZ(  
      D xPgBV~  
分析:C错,应改为her。his指男性,显然是错误的,应改为her与后面的her同指Amy Lowell. ^.G$Q#y,  
] - .aL  
-N@|QK>  
(四) Who和which的区别 & ~!Wym  
which指代事物或者动物,who指代人  IB<d  
who/whom son往往要改为whose son, whose可以指代事物 fh{`Mz,o  
9kojLqCT  
例:The human body contains more than six hundred muscles who 3F0 N^) @  
              A            B ccnK#fn v  
  account for approximately forty percent of the body weight. l@\FWWQ  
   C                  D R4@ 6G&2d>  
分析:B错,应改为which或that。先行词不是指人,而是指物,关系代词不能用who,故改为which或that。 `kr?j:g  
人体前面加定冠词the, account for 占有多大的比例,解释说明 6Iw\c  
 9 a kH  
(五) that和which的区别 {|\.i  
介词后面使用which, 而不用that, in that除外 KF/-wZ" 1s  
H:G1BZjq  
例:When television was first introduced, the extent to that it 7 ?t6UPf  
              A        B v@Ox:wl>  
  would affect society could not have been foreseen. 3~ \[7I/  
      C              D vI]N^j2%  
分析:B错,应改为which。The extent to which, 介词加which(引导定语从句),影响社会的程度没有被预见 \?N2=jsu$  
4OX^(  
(六) 定语从句的特殊省略 p:%loDk  
Reason后面有定语从句,中间往往省略why, 'RRE|L,  
Time后面有定语从句,中间往往省略when go"Hf_  
   I do remember the time I heard the sweetest voice in the wild world. :Yks|VJ1  
way后面有定语从句,中间省略了in which qw8Rlws%  
%IRi1EmN8  
例:Research on pain has been neglected, although the mainly EP+J N  
              A         B   m`_ONm'T&  
  reason people take medicine is to relieve pain. :@)>r9N  
         C      D Q&V;(L62!  
分析:B错,应改为main。mainly为副词,不能个饰后面的名词,故改为形容词main。句子中people take medicine修饰reason,定语从句引导词被省略 _y>~ yZx  
_y3Xb`0a  
例:Commercial expansion from city to suburb has  Z<4AL\l 98  
  affected the way people in the United States----. f9\X>zzB2|  
   (A) living and working \15nS B  
   (B) they live and work V!dtF,tH  
   (C) live and work rt| 7h>RQ  
   (D) to live and to work yA>nli=  
分析:选择C, the way people....影响了人们生活和工作的方式。 4{l,  
f`/x"@~H5  
二、介词 OC:T O|S:4  
介词是考试中出现的比较多的一个部分,而其中考的最多的就是介词的固定搭配问题。由于篇幅问题,我们在这里仅仅举出几个例题,在说明书手册中我们完整的列出了所有的介词搭配,这些列出的搭配在以前的语法题中出现过,只不过有的时候是正确的选项,有的时候重复考。 VQ{fne<  
pBPl6%C.X-  
(一) 介词搭配 2"S}bfrX  
->{KVPHe{  
例:The teeth in the upper jaw function together those 3Le{\}-$.  
    A         B   C      B~du-Z22IZ  
  in the lower jaw to cut, tear, and grind food. Ib0ZjX6  
                D rc>6.sM %  
分析:和…一起,应该为together with,C错 )];K .zP  
[66! bM&  
例:The Allegheny Mountain range is rich of coal. gl_^V&c  
A       B     C  D ,'iE;o{Tu  
分析:B错改为be rich in 8'r[te4,  
TvQo?  
例:The rotation of the Earth on its axis is responsible to the C{XmVc.  
    A         B      C T${Q.zHY[!  
  alternation of periods of light and darkness. BI}Cg{^km  
             D m<g~H4  
分析:C错,应改为responsible for。形容词responsible后接名词作宾语时要加介词for。 c:u5\&~{  
Ji 0 tQV  
E\2%E@0#  
(二) 最重要的两个介词 19KQlMO.G  
1、介词of 多余或者遗漏 BIWWMg  
例:Mosquitoes usually lay eggs, singly or in batches, on top stagnant water. )D82N`c2\i  
          A      B  C     D Ezv Y"T@  
分析:D错,应改为top of stagnant。on top of …是因定表达法,意为“在…上面”。 a+T.^koY  
78H'ax9m  
例:Christopher Plummer is a Canadian actor who has Mzw X>3x  
                 A  B     *``JamnSO  
  starred in stage, television, and film productions on m<qJcZk  
      C  y%b F&  
  both sides the Atlantic Ocean. `P;s 8~  
      D \`\ZTZni  
分析:D错,应改为sides of the。 sides为名词,the Atlantic Ocean也是名词,中间明显少了一个介词。 gy9U2Wgf|  
}:*]aL<7_  
2、介词by Ziu]'#  
一种情况表示被动,be+过去分词+by :+|Z@KB  
另一种表示通过……的方式, by doing  A4<Uu~  
例:The ceremony of marriage in the United States df#$ 9 -  
    A         B       JNUt$h  
   can be performed from a justice of the peace. u4%Pca9(=  
   C     D P&e\)Z|  
分析:D错,应改为performed by。谓语动词是被动式,performed的动作执行者应该由介词by来引导。 ;<2 G  
U,-39mr  
例:Along the east coast ,American Indian women's councils l.bYE/F0&  
   A                      fG(SNNl+D  
   could veto a declaration of war at refusing to Jh[UtYb 5  
     B    C       D -kwXvYu\  
   supply moccasins and field rations. oVe|M ss6  
分析:D错,应改为by refusing。通过拒绝提供鞋子和粮食,表示通过某种方式做某事要用介词by,故将at refusing 改为by refusing。 K_ ~"}  
=k0_eX0  
例:Algebra is the branch of mathematics concerned with >R! jB]5  
        A                o,8TDg  
  operations on sets of numbers or other elements G&V/Gj8  
        B          C   "z=SO1  
  that are often represented at symbols. Om@C X<(9C  
              D C-MjJ6D<  
分析:D错,应改为by。动作的发出者应该用介词by来引导。 :Ab%g-  
三、谓语动词 wN-d'-z/rd  
(一) 谓语动词的主谓一致 GV69eG3bX#  
①、主谓分割原则 =i*;VFc  
例1:To the citizens of the United States, the bald eagle,  %)I{%~u0  
     A     C$D -Pt"+  
   America's national bird, symbolize strength and freedom. tL) t"  i  
        B      C      D j<@lX^  
分析:C错,应改为symbolizes。主语谓语用逗号分割开,主语the bald eagle为单数,谓语动词也应该用单数形式。 =~H<Z LE+  
4$S;(  
②、与后者一致原则 'JfdV%M  
not…but, 强调but后面的名词, 78# v  
not only…but also ;n=.>s*XL'  
` a/%W4  
]d0tE?9  
③、与前者一致原则 a\E:sPM'>  
名词+with/together with/as well as/including+复数名词,谓语用is, _EMwm&!  
中心词在前面,谓语动词应该与前面的名词保持一致 .=;3d~.]  
例:The athlete, together with his coach and /1Q(b  
     A      B  C     M .JoHH  
  several relatives, are traveling to the Olympic Games. E}p&2P+MR  
         D _Khc3Jo  
分析:D错,与谓语动词与the athlete 保持一致,改为is 4?7W+/~<&  
ps%q9}J  
④、就近原则 <| +Ex  
or, either…or, neither…nor, n3Z 5t  
单数名词+or+复数名词+are V'T ,4  
如果把句子变为一般疑问句,也就是把be动词提到前面,那么变为is (>GK \=:<  
所以注意一点: 如果是陈述句,靠后面近,用复数 7Ka l"Ew  
        如果是疑问句,靠前面近,用单数 !~&R"2/  
5>j)kx=J9  
例:The structure or behavior of many protozoans are [[Fx[  
        A      B        tj4VWJK  
  amazingly complex for single-celled animals. CS-uNG6  
    C              D ;YX4:OBqr  
分析:A错,应改为and。从谓语动词是复数形式判断,主语应该为复数,or连接两个名词时动词和后面的名词保持一致,behavior是用单数形式,因此只有改为并列连词and才能使主谓在数上保持一致。 I'iGt~4$  
;z:UN}  
⑤定语从句主语就近原则  &8_gRP  
There are five apples that are red. b7tOo7aH)  
apples是复数,因此从句谓语动词是复数。 U1RpLkibQ  
>W`4aA  
例:A rocket burns propellant rapidly and most rockets `~;rblo;  
      A            C@W"yYt  
  carry a supply that last just a few seconds. &2zq%((r  
   B   C    D e\JojaV  
分析:D错,应改为lasts。从句的逻辑主语a supply为单数,其谓语动词应为单数形式。 }S$@ Ez6  
x{c/$+Z[  
⑥the +形容词主谓一致 Z%Zd2 v  
The rich are not always happier than the poor. nMvKTH  
The rich 表示一类人,应该用复数 5~WGZc  
q]N:T pm9  
⑦、倒装句的主谓一致 [$"n^5_~  
改错题倒装句的主谓一致一般考两种情况: R&';Oro  
a. there be 句型 ez!C?  
there be+名词+名词,那么最近的名词决定其形式 09kt[  
b. between/ among 放在句首+be+名词,名词其实是主语,所以be和名词保持一致 snnbb0J  
L^4-5`gj  
例:There are no known society in which left-handed people predominate. /'DsB%7g  
   A     B      C    D    ['*8IWg  
分析:there be 句型由最近的名词决定其形式,society当然用单数,A错,there are 改为there is (S`2[.j  
`o?Ph&p}  
vp cr PVA^  
例:Between the foothills of the Andes and the Pacific S^<g_ q  
             A     B    \Z/)Y;|mi0  
  Ocean are a dry coastal strip averaging about 30 @L:>! <  
     C         {$^DMANDx  
  miles in width. 0 Ir<y  
     D  x5WW--YR+  
分析:倒装句,are改为is +@K09ge  
IMl!,(6;  
例:Among the favorite attractions at the National Air and u@% r  
   A    B       C         Tl|:9_:t  
  Space Museum in Washington D.C. are the film -+em!g'  
                    D 4r0b)Y & I  
  presented on the five-story-tall screen. i^!ez5z  
分析:D错,应改为films , 主语实际上是名词,应该与谓语动词保持一致。 Q;J`Q wkH  
eBO@7F$  
⑧、百分比结构的主谓一致 "AhTH.ZP  
fifty percent of + 名词 ~|AwN [  
one percent of + 名词 a9?y`{%L  
谓语动词的形式和百分比多少没有关系,主要取决于后面的名词,比如: I;?X f  
  one percent of my students + are VCcr3Dx()F  
  fifty percent of my time is spent on working. `[YngYw  
vHE^"l5v  
这里要强调两个结构 oo$MWN8a>r  
half of =fifty percent ?P7] u>H  
most of + 可数名词 + are |J~eLh[d  
most of + 不可数名词+ is :ECi+DxBK  
@v*/R%rv t  
例:Nearly half of the ancient meteor craters has been GBC*>Y  
   A       B         C   i o3yLIy,  
  found in central and eastern Canada. .\qj;20W  
           D 2w$t wW-  
分析:C错,应改为have been。介词of的宾语为复数名词短语,作主语的中心词half当然表复数,相应的谓语动词应为复数形式。 nB ".'=  
Sm2>'C  
例:Approximately fifty percent of the package utilized $Vv}XMxw  
                 A   B  Z2bcCIq4  
  in the United States are for foods and beverages. ^5 t  
              C     D 1 Ee>S\9t  
分析:A错,应改为packages。从谓语动词用复数形式判断出主语是复数名词。注意food用复数表示不同种类的食品,beverage用复数表示不同种类的饮料,故(C)、(D)均没有错。 D["MUB4l  
vG2b:[W  
(二) 谓语动词的时态 qYp$fmj  
①、主要考察时间状语 s2v(=  
WnAd5#G  
例 The metal aluminum has been first isolated early in the nineteenth century. m$$?icA  
   A        B  C     D fH8!YQG8$  
Cv=GZGn-  
分析:Metal, aluminum同位语,in the nineteenth century为明显表示过去时间的状语, 因此应该用过去时态,把has been改为was ]wuy_+$  
.]}N55M  
 \`xkp[C  
②、For和since的区别 P l{QOR  
区别一:For 后面使用时间段,since 后面使用时间点 1:= `Y@.S  
区别二:Since 只能用在现在完成时态,For 最主要用在现在完成时和一般过去时 X^@[G8v%  
  I has been a teacher for three years. }1%r%TikY  
  I has been a teacher since 1996. S9Yt1qb  
  I was a teacher for three years. 这种表达可以,for three years表示一段时间,was 表示过去做了三年,现在不是老师了 $~'T f>e  
O(OmGu4%  
例: Since 1921 the budget of the United States became uiBTnG"  
   A      B              Eo{EKI1  
  the primary responsibility of the president. X$wehMBX  
     C    D ;>2#@QP  
分析:A错,应改 In. since一般要求主句用完成时态,而句中谓语动词为过去式,其时间状语应与之呼应,故改Since为In。 g<[rH%\6fg  
<uF [,  
例:Adella Prentiss Hrghes served as manager of <4D%v"zRP  
             A  B  C   X_70]^XL  
  the Cleveland Orchestra since fifteen years. ~/`X*n&  
            D Z%v6xP.  
分析:D错,应改为for。since引导时间状语时,主句谓语动词为一般完成时;主句谓语动词为一般过去时要用介词for;而且一段时间用for, 而不是since。 vg5NY =O  
"]]q} O?  
2X @G"  
52. In general, prawns lived in shallow coastal waters or in streams.  \mXqak,y  
   A       B        C     D / = ^L iP  
自然现象和客观事实用一般现在时态,live 9 p> /?H|  
s[-]cHQ  
(三) 谓语的语态 E8tD)=1  
语态主要表示是主动语态还是被动语态。 /{G/|a  
有四组动词是改错题中常考的: d1NE%hg3  
①、prove VBx,iuaw  
My advice proved to be wrong. 我的建议被证明是错的 Y(GW0\<  
尽管是被证明,但习惯上用主动; #S i|!  
Bz]J=g7  
例:A majority of the reports received from people claiming Ve14rn  
                      A   ^W['A]l  
  to have seen the legendary Loch Ness Monster have proven to be .S|-4}G(6  
    B                  C p}8ratmN  
  mistakes, misconceptions, or they were being tricked. v>^jy8$  
                  D |!5@xs*T  
分析:D错,应改为tricks。并列连词 or在此连接名词,如果把D理解为并列句,不仅时态不对,语义也有问题,故将整个句子改为名词。have proven to be是正确的。 v@,XinB[  
n1)'cS5}  
dP3VJ3+ %  
②、Locate,Situate S&|VkZR)  
这两个词可以用作主动,表示把…放置在…地方;确定…的位置 Vw?P.4  
  Bats locate obstacles.蝙蝠确定障碍物的位置 'WzUu MCx  
这两个词也可以用作被动 $9m5bQcV  
  My school was located near the river. \I xzdFF#  
区分locate的主动和被动比较难,但是有一个技巧存在:locate如果用作主动,后面必须跟宾语 w#d} TY  
例:The center of gravity of the human body ---- behind the hip joint. 2?H@$-x>  
   (A)locates />!!ch  
   (B)locating )x9]xqoR  
   (C)to locate Vd[  2u  
   (D)is located \y,; Cfl<  
分析:空格处显然缺谓语动词,故首先排除不能作谓语的B和C。动词locate后面没有宾语,所以用作被动,表示“位于”,所以D为正确选项。 |N6mTB2  
EUXV/QV{  
③、表示需要概念的动词 Z c<]^QR  
need, want, require等 ?P YNE  
yx 7loy$[  
My watch needed repairing XNK 43fkB.  
My watch needed to be repaired. PgqECd)f  
(S3jZ  
④、表示人的情感的动词 &(WE]ziuO  
move, annoy, surprise, please等 4=UI3 2v3  
0ZFB4GL  
He is so moving.  他令人感到感动。 Vz k cZK  
He is greatly moved. 他感到非常感动。 NywB 3  
2;O  c^  
主动和被动技巧总结: Za34/ro/T  
如果句子中有一个“过去分词+by”, 如果断定它是谓语的话,前面必然有be动词 '>"`)-  
yi&?d&rK  
例:The Tennessee Valley Authority has chartered by the 5 7'q;I  
                 A      %{=4Fa(Jux  
  United States Congress in 1933 to construct dams, EmYO5Whi

  power structures, and flood-control works along rK*hTjVn  
                    C X"laZd947>  
  the Tennessee River and its tributary streams. xAFek;GY?  
                D 32TP Mk  
分析:A错,应改为has been chartered。由信号词by可知前面的谓语动词为被动语态形式。 BW+qp3k\  
aS3P(s L  
四、非谓语动词 6R0D3kW  
L;L2j&i%v)  
(一) 分词 2#,8evH  
现在分词和过去分词的区别 M|$H+e } :  
①、用于句首作状语,现在分词表示主动,过去分词表示被动 ;:-}z.7Y  
W,0KBkkp  
例:Won its war for independence in 1783, the United States then Xcs8zT  
   A oiIt3<BX  
  struggled to establish its own economic and financial system. |p'_k(z}  
     B      C            D ke{DFq h  
分析:分词作状语,主要看是主动还是被动,美国赢得应该是主动,所以A错,改won为winning }M;sz  
pT|./ Fe  
②、用于名词后面作后置定语,现在分词表示主动,过去分词表示被动 2 rbX8Y  
例:In the nineteenth century the Mohave Indians lived in WBIQ%XB'  
      A               B   V3aY]#Su  
  the Northern Hemisphere grew their crops on river bottom lands. (!^N~ =e;  
               C         D F#zQQ)(Pf  
分析:B错,生活在什么地方的人,人生活是主动,因此改为living Lh8# I&x  
UMnR=~.  
%D%e:se  
一些动词后面必须用doing +_vm\]4  
对于加doing的词来说,考试中一般出现一个,下面这些词都是要加doing的,请考生牢记。 gDUoc*+h  
 mind, finish, enjoy, celebrate, ]~4}(\u  
 advocate, suggest $~;6hnr m  
 delay, quit ?STI8AdO  
 forgive(原谅),tolerate, >d1aE)?  
 avoid, escape(逃避) /9t*CEu\  
 spend+名词+doing; [qc6Q:  
 have trouble/difficult/a problem/ +doing Lx4H/[$6D  
+4p2KYO  
例:Long before the dawn of recorded history, humans celebrated to harvest their \, X?K  
   A     B    C              D $n_sGr  
  crops. Z=1,<ydKV  
分析:D错,应改为harvesting。及物动词celebrate直接带名词、名词短语或动名词短语作宾语,故将to harvest改为harvesting。 :Kt mSY

  the habits that might shorten the lives. 2* cKFv{  
         C     D I "+|cFq.  
分析:D错,应改为their. 定冠词在句中不如代词所有格明确,如果lives后面有定语就可以用the。注意(A)并没有错,help后面可以接不带to的不定式。  I$sm5oL

五、句子的结构 rlq8J/0/+  
句子的结构主要考查四个出题方向。 .gB*Y!c7  
fg2}~ 02n  
(一) 主语的重复 >}iYZ[ V  
名词+代词+谓语,这个代词永远是重复的主语,永远是错的 j<[<qU:  
例:Woodrow Wilson he was an idealist who refused to make any PF~&!~S>W  
          A      B      f`Nu]#i  
  compromises concerning the establishment of the +J2=\YO  
          C          D @S{,g;8  
  League of Nations. e>[QF+e)y  
分析:代词he不是同位语,主语重复;如果是下面这样的主语,那么便是主语同位语 +Fk.B@KT,  
A prolific writer, Woodrow Wilson BkcOsJIz  
plca`  
WVV qH_  
例:Two unique features of the Arctic they are a}yJ$6xi  
        A        B  _+GCd8d  
  lack of precipitation and permanently frozen ground. .gB#g{5+J  
    C         D q o'1Pknz  
分析:选项B中的they和前面的主语two unique features重复 B|8(}Ciqx  
{2,V3*NF  
(二)谓语的重复 +f+\uObi:  
完整的句子后面又多了一个谓语,往往改为定语从句 '+$2<Ys  
W>Zce="_gN  
例:A paragraph is a portion of a text consists of  VB Ce=<  
    A            B    SQ@@79A  
  one or more sentences related to the same idea. RAe:$Iv$!v  
         C   D "B.l j)  
分析:B错,应改为consisting of或which consists of。句中有两个无法连接的谓语动词,而且前一个谓语动词下面没有划线,故改consists为非谓语动词形式或在它前面加which使之成为从句谓语动词。 CEwG#fZ  
IE3GM^7\  
(三)谓语的缺少 c1c0b|B!U  
例:Most mammals to maintain a relatively constant body oYu5]ry  
          A     B    Qq5)|m  
  temperature, regardless of what the air temperature might be. Zf|f $1-  
         C               D )=~1m85+5B  
分析:A错,应改为maintain。句中缺谓语动词,故去掉不定式符号to 使maintain变成谓语动词。 0%vXPlfnY  
&DgIykqN  
(四)主句的重复 Q+S>nL!*#1  
主句的重复总是考even, instead, during, despite等引导的句子, 但是实际上它们无法把两个句子连接起来,因为它们都是副词或者介词,连接两个句子应该用连接词连接 4rv3D@E  
% `\8z  
R/U"]Rc  
例:Salmon spend most of their adult lives in salt water, despite OE W IP  
      A         B        C   9_oIAn :<  
  they return to their freshwater birthplaces to spawn and die. .F &\xa{  
     D [p|-G*=00  
分析:C错,应改为though。despite是介词,后面一般接名词作宾语,而在句中它后面却跟着一个完整的句子,所以改为连词though。 vV,H@WK  
5Y JLR;  
例:Solar eclipses occur during the Moon's shadow 2 ES .)pQ  
        A   B       >cQ*qXI0  
  sweeps across the face of the Earth. ZI-)'  
      C    D 9-I;'  
分析:B错,应改为when或as。介词不能引导条件状语从句,根据题意改为从属连词when或as。 !Tr +:SM  
ZoF\1C ^  
例:Even many early leaders of the United States have provided JEGcZeq)  
   A                     B  B/&axm%0  
  names for towns, only George Washington 52,pCyU  
      C /!uxP~2U  
  is remembered in the name of a state. 2>_6b>9]  
          D UXnd~DA  
分析:A错,应改为Even though。even为副词,不能引导从句,根据题意,改为引导让步状语从句的Even though。 fOF02WP^  
六、比较级和最高级 H@.j@l  
比较级和最高级的出题非常有规则,一共有5个出题方向,并且每次考试必然考两个 QB7E:g&7  
`[2nxP>w`  
(一)    比较级或最高级形式上的重复 j"7 z  
例:The most easiest process for mining gold is panning, which Nj@k|_1  
      A               [j`It4^nC  
  involves using a circular dish with a small pocket at the bottom. H*?U@>UU  
     B       C           D &NL=Bd  
分析:A错,应改为easiest。easiest本身已是最高级,不必再用most,这是最高级形式上的重复 r*OSEzGUz  
o5-oQ_ j  
(二)比较级和最高级之间的混用 ~6Vs>E4G  
例:The greenest and plentifulest leaves are the leaves of grasses. k:nr!Y<  
     A      B     C  D K, WNM S  
分析:B错,应改为most plentiful。 plentiful是多音节形容词,须在前面加most构成最高级。 FAzshR  
G29 PdmY$<  
例:The more fearsome of all the animals in the Western Hemisphere pej/9{*xg(  
     A       B     C   D ?kI-o0@O.  
  is the grizzly bear. By]XD~gcP  
分析:A错,应该用最高级most,含有介词of, among, in 表示的范围状语使用最高级。 [-x~Q[  
)!SVV~y  
y{0`+/\`  
(三)比较词than的前面一定要有比较级 ;XMbjWc  
改错题中,通常会看见than前面有一个原级 mqrP0/sN  
I3uaEv7OZc  
例:Film directors can take far great liberties in dealing with d+[yW7%J  
   A           B  Py^F},?J  
  concepts of time and space than stage directors can. iW(HOsA  
   C                 D B; r U  
分析:B错,应改为greater。根据后面有than一词可以判定前面的形容词用比较级形式,注意far, much 修饰比较级。 idMb}fw>  
@NWjYHM[`  
(四)在as…as以及否定not so…as, not as…as的中间使用形容词原级 4_Tx FulX.  
as sweeter as, 这是不对的,应改为as sweet as :DXk Ab2  
};o6|e:2E  
(五)the 和比较级最高级的关系 7L|w~l7R~  
①、比较级前面可以出现the, 修饰后面的名词 Qw!cd-zc  
the taller boy bg[k8*.:F  
&PI}o  
②、副词的最高级加不加the均可以 odMjxWY  
例:Although flies live longest in cool temperatures, it breed 6a[D]46y,2  
          A            B Q^$IlzG7i  
  prolifically when temperatures are warm, food is GM U.Kt  
  abundant, and humidity is moderate. =24)`Lyb  
    C          D <"{Lv)4  
分析:副词的最高级加不加the均可, 所以A正确,从从句的主语可以看出,B应该改为they )tl=tH/$  
Z#BwJHh  
③、形容词的最高级作定语前面必须使用the, 如果不作定语的话,加不加the均可以 0 60<wjX6  
例:Of all the Native Americans in the United States, 7Te`#"  
  A  B         C     "(PJh\S>S  
  the Navajos form largest group. \Si@t{`O  
         D 8+{WH/}y8  
分析:D错,应改为form the largest。形容词最高级前面要加定冠词。 ;X<#y2`  
w~y+Pv@   
陷阱1, earliest, 有两种可能, x.qn$?3V]  
一种可能是early的最高级,最早的语言,the earliest language XL c&7  
    另一种可能作名词,表示早期,必须和时间的名词连用,earliest time, earliest ages, 表示很早的年代,很早的时代,也就是说,如果以后碰上earliest后面加上times, ages, 前面不用加the +Gqh  
e;~[PYeu  
例:The belief in fairies have existed from earliest times, and the literature of many e.hHpjWi?Z  
            A      B         C "(5A 5>  
  countries includes tales of fairies and their relationship to humans. 9_V'P]@  
            D htk5\^(X  
分析:A错,应改为has existed。主语是单数名词the belief,而不是复数名词fairies,故谓语动词是单数形式。earliest times表示表示很早的时代是正确的。 ]^$&Ejpe#  
<use+C2  
陷阱2,如果最高级前面有所有格的话,不用加the 8.HqQ:?&2t  
例如:my best friends G 5w:  
"]>JtK  
例:Salt Lake City, Utah's capital and largest city, is industrial B;9X{"  
            A    B     C *2N$l>ql:k  
  and banking center. Ug*:o d  
        D u:tLO3VfJ  
分析:C错,应改为is an industrial center。center为可数名词,它的修饰词前面应有不定冠词。 \_ }Y4  
Utah's largest city, 题目中其实是省略了Utah's。 ba& \~_4  
fQRGz\r*k  
5 BR 9f3}  
例:Faults in the Earth's crust are most evidently in sedimentary )pLde_ k  
                 A         :\9E%/aAD  
  formations, where they interrupt previously continuous layers. DcaVT]"  
    B   C     D U1G"T(;s:  
分析:A错,are的表语必须用evident, 为什么不加the, 因为作表语,而不是定语 :pj#t$:!  
7y.$'<  
七、平行结构 +F$c_ \>  
改错题考的最多的一个方向便是平行结构 +#7 e?B  
 +LeZjA[  
]+\;pb}bq  
(一) 对等连接词 :S'P lH  
一共有三类连接平行结构的词 IoWh&(+KdH  
单一式: and, or ,but kaf4GME]  
相关式: both…and, not … but, Y ]&D;w  
     either …or, neither…nor {^zieP!  
     the same…as;as…as, not so…as, not as…as W m\HZ9PN  
     such …as, so …that.. too…to, from…to, from…until, $}RBK'cr}  
没有so...as... XM o#LS  
between…and, XA75tU[#  
     not only…but also(also可以省略),Not only +主谓,also 5<h7+ %?t9  
     not only…but also(also可以省略)+as well, ``KimeA~  
>KX Sb@  
短语式: as well as cnJ(Fv_F$  
     rather than (而不是) s<,[xkMB  
     other than (除…之外) O2./?Ye  
     instead of (代替) A (z lX_  
3 >;zk#b2  
考试的方式往往是搭配中有一个单词是对的,另一个单词却不对 d Bn/_  
例:John lived in New York since 1960 to 1975,  ~k>H4hV3  
       A     B   9>,$q"M}?  
  but he is now living in Detroit. {jB& e,  
       C   D &,E^ y,r  
分析:B错,应改为from。“从某年到某年”要用“from…to…”这个表达法,不能用since …to…。 5n,?&+*L  
=(\ /+ 0-[  
例:Even as he wrote copiously on so diverse topics ?Pg{nlJvq  
       A         B Z,~Bz@5`"  
  as education ,politics ,and religion ,Lewis Mumford BPRhGG|9j  
  remained active in city and regional planning. nO-1^HUl  
          C    D  4#D=+70'  
分析:B错, 改为such diverse topics as, 出现as, 往往要注意前面一半 [!Uzw 2  
(二)平行的内容 v&}+ps_W  
第一、引导词性的平行,词性的平行本质上是语法作用的平行 7nr+X Os  
例:Photoperiodism is the functional or behavioral response of d@-s_gw  
             A         B   ~J #^L *  
  an organism to changes in duration of daily, seasonally, f0 iYP   
         C            D ~+ _|J"\  
  or yearly periods of light and darkness. ;yd[QT<I<  
分析:D错,应改为seasonal。在daily, seasonally和yearly三个并列的词中,daily和yearly是形容词,seasonally是副词,故改为形容词seasonal,共同修饰名词periods,三个形容词的平行,词性平行 QN!.~>  
2@!Ou$W  
h$\+r<  
第二、名词单复数的平行 .4I "[$?Q  
但是如果既有可数名词,又有不可数名词,可以不平行 8Ter]0M&  
R^t )~\d  
例:The main advertising media include direct mail, @C \>P49  
  A     B          C   fg[]>:ZT.  
  radio, television, magazines, and newspaper. LHy-y%?i  
                 D   i;+]Y   
分析:D错,应改为newspapers。newspaper为可数名词,在没有任何前置修饰语的情况下一般用复数形式,并且和前面的magazine平行,而mail, radio, television则是不可数名词。 \gtI4zl*J  
J})#43P  
例:The Canadian province of Newfoundland has a rocky coast, a moisture climate, ChVur{jR  
                   A         B funHz nRR  
  and probably the best cod-fishing areas in the world. o XKH,r  
      C          D V s/Z8t  
分析:海岸气候只有一个,但是钓鱼的地方可以有许多个,所以也是不可数名词和名词复数的平行;因此D没有错,A错改为have Mv\odf\]  
8Xo`S<8VS  
第三、时态的平行 :Ng4? +@r  
例:The poet Marianne Moore was initially associated W_]Su  
                A     D4';QCwo  
  with the imagist movement , but later develops kqyV UfX$3  
                   B C3m](%?   
  her own thyme patterns and verse forms. u<}PcI.  
          C    D D7'P^*4_B  
分析:B错,应改为developed。句中前半部分谓语为过去时,与之并列的谓语也应用过去时。 jg,oGtRz  
KN41 kkN  
例:Because the papaya grows readily from seed , ----- SL( WE=H  
  spread from its home in Central America and n aQ0TN,  
  now grows throughout the tropics. J}c `\4gD  
   (A) to be    (B) it   NZj_7j|o9  
   (C) the     (D) its >'qkW$-95  
分析:正确答案为(B)。空格前是原因状语从句,后面紧接着是谓语动词,空格处明显缺主句主语。四个选项中只有B能单独作主语。注意spread是过去式,没有数的变化,因为这一动作明显发生在过去时间。spread 和grows为什么时态可以不平行呢? ch^tq",1>  
原来它在Central America 的家乡传播,现在在整个地方传播,now只修饰后面的grow IV#kF}9 $  
i;'kQ  
例:Ducks have been domesticated for many centuries ---- VaLx-RX  
  commercially for their meat and eggs. uTSTBI4t  
   (A) raised   (B) and are raised Wa/&H$d\u@  
   (C) raised as  (D) are raised %Pz'D6 /  
分析:正确答案为B。空格前是一个完整的句子,根据一个空格处如再出现谓语动词一定要有连词这一原则,B为惟一符合条件的选项。故选(B)。 ]["=K!la:  
vCPiT2G  
第四、排列位置的平行 Hl@)j   
例:---the surface of metal, but also weakens it. 319 &:  
   (A) Not only does rust corrode Rs Y7F;  
   (B) Not only rust corrodes  0cd`. ZF  
   (C) Rust, which not only corrodes 'CTvKW  
   (D) Rust not only corrodes *1Q~/<W  
分析:正确答案为D。从but also放在动词前可知,not only也须置于动词前,故选D。A、B中的Not only位置放错了,C使句子缺主句,故排除。 FIB 9W@oao  
x B%Felz  
对于not only, but also的用法有以下几种: B%|cp+/  
 1、主语+not only +谓语,but also+谓语,正确;例如上面例题中的第四个选项。 @0XqUcV  
 2、Not only +主谓,but also+主谓,正确 =h`yc$ A(2  
 3、Not only +主语+谓语,but also+谓语,错误 "`s r#  
i2PPVT  
八、词序的颠倒 8z?q4  
词序的颠倒一般只考一道,90%的情况集中于下面三个出题方向 ?q&*|-%)_d  
(一) 先说形容词,再说名词 ypoJ4EZ(  
例:The Medal of Honor is the highest award military for courage Sdc yL%6!  
              A    B        ?qn0].  
  that can be given to any individual in the United States. rv(Qz|K@  
      C       D    mP1EWh|  
分析:B错,军事的荣誉是military award而不是award military,单个形容词修饰名词时一般放在被修饰词的前面。 CC(At.dd  
N8<Wm>GLX~  
s^ t1T&  
(二) 副词+形容词+名词 1gq(s2izy  
例:Certain types of computers work properly only S nMHk3(\  
          A      B     U!GG8;4  
  in environments with controlled precisely temperatures. [V\0P,l  
    C         D ~*Fbs! ;,  
分析:D错,应改为precisely controlled,精确的被控制的温度。controlled为过去分词用作形容词,修饰它的副词应放在其前面,它自己则要紧挨着被修饰的名词。 n4albG4  
3NEbCILF  
BE54^U  
(三)主语系动词, 系动词 + 表语 &^R0kCF`  
gFJ. p  
例:During the 1600's skilled shoemakers scarce were dS7?[[pg9  
          A   B     C   QLq^[ >n  
  in what is now the United States. 7XE |5G  
    D 'USol<  
分析:C错,应改为were scarce。表语应该放在系动词后面。 =WaZy>n}7  
GqFDN],Wp  
所有的系动词分为三大类: 0]tr&BLl*

    seem(好像是) PU0Ha  
    look(看起来好像是) N5>ioJj  
    feel, sound, appear, smell, taste Zt3"4d4  
enough修饰形容词或副词时,一般放在形容词或副词后面。 M2UF3xD   
例: The eruptions of Mt. St. Helens were enough severe  .;ptgX  
    A               B     89*txYmx  
   to cause numerous deaths. idWYpU>gC  
        C   D  SE%B&8ZD  
分析:B错,应改为sever enough。severe是形容词, enough放在severe后面。 inO)Y]|f

九、词性的混用 JI TQ3UL:W  
词汇量的掌握对词性的使用非常重要,但是如果对出题方向有更好的把握,将会弥补词汇量的不足。 `Sh#> Jp

(一)做表语时形容词和副词的混用 2Zf} t  
做表语永远用形容词,绝对不能用副词; ~Z74e>V%  
,(h:0L2v7d  
例:Giant pandas, which inhabit restricted areas of high El3Y1g3+3  
          A        B      5F#Q1gP-  
  mountain bamboo forests, are rarely today and wR)U&da`@  
              C %Vf3r9 z  
  when they are in captivity they breed poorly. TvV_Tz4e  
          D `zD]*i(  
分析:错,应改为are rare。rarely为副词,不能作表语,故改为形容词rare(罕见的,稀少的) 8ZmU(m  
uB;\nj5'D  
 58S>B'  
(二)加宾语时名词和动名词的混用 in>Os@e#  
后面加宾语当然要用动名词 >A'Q9Tia;  
例:Tilling means preparation the soil to plant the seeds H0!W:cIS;l  
         A       B      ,;RAPT4  
  and keeping the soil in the best condition to qnFi./  
          C        o75Hi t  
  help the crop grow until it is ready3 for harvesting. :Z(w,  
            D 9j[lr${A  
分析:A错,应改为preparing。preparation为名词,后面不能接宾语,改为动名词preparing后既能接宾语,又与后面的keeping构成并列关系。 <oF ZFlY@  
E=G"_ ^hCE  
例:Langston Hughes, a prolific writer of the 1920's, l1<]pdLTR  
            A       ;|C[.0;kgv  
   was concerned with the depicting the experience of -w>2!@8  
      B      C 9E@}@ZV(  
   urban Black people in the United States. "pa}']7#  
   D <i<[TPv";  
分析:C错,应改为depicting。 depicting在此为动名词,作介词宾语时不加冠词。注意此处还可以改为the depiction of,但略显累赘,因为后面还有of结构。The +动名词,这个动名词其实就变为了名词。 hxt,%al

####(三)表示时间时,状语从句连接词和近义的介词混用 :6N'%LKK  
表示时间有两种可能, ")gd)_FOS  
一种是状语从句,由when and while引导,后面加句子 .}xF2'~E/  
另一种是由介词引导,如during,后面加名词, PO$ OXw  
考试中往往就利用这个特点,总是给出相反的情况 0=WZ 8|R  
z_gjC%(y  
例:Balloon observations for military intelligence $qvk9 B0E  
       A     B     TB oN8cB}  
  were made while the American Civil War. ?zS t  
   C    D &5x ]9   
分析:D错,应改为during。while是从属连词或并列连词,后面接句子,后面是名词短语时,应改为介词during。 RyAss0Sm^  
J2va Kl  
例:Some of the most celebrated publicity stunts while the #iZ%CY\  
   A      B           C    \[!k`6#t7  
  history of radio were associated with Gracie Allen. w ^rINPAS  
          D )/B' ODa  
分析:C错,应改为in。while为连词,后面要求接从句,而句中显然没有从句,故根据题意改为介词in。 >3{l"SPU

(四)对等连接词和近义的副词混用 _NkVi_UX  
连接平行结构的词叫做对等连接词,但是如果出现else, also, instead等副词把这些结构连接起来行不行呢?当然不行。 SccaX P  
@~Uu]1  
例:Mary McDowell shared Jane Addam's interest in social #RyX}t X,  
                   A     2$Fy?08q  
  work also was a loyal supporter of the League of Nations. a$7}41F[~s  
     B   C    D NI1jJfH|l  
分析:B错,应改为and。also是副词,不能连接并列的谓语动词,故改为并列连词and。 gbl`_t/  
IPIas$  
例:Paper is strong under tension instead crumples 5y1:oiE/  
   A        B   C      |KC!6<}T~9  
  easily under the stress of compression. 9/@7NNKJ  
   D G!^}z (Mgi  
分析:C错,应改为but;题目意思是在拉力的作用下很强,而在压力的作用下容易起皱;instead, 副词不能连接两个动词并列,but 的对等连接词和and, or的用法是一样的 h"/y$

(五)表示人的名词和表示事物的词混用   OH*  
Kb/w+J S  
例:An editor is customarily a brief newspaper or magazine Q)$RE{*-  
    A         B qrK\f  
  article that gives personal comments on current events. v'vYN h  
          C            D :d!qZFln  
分析:A错,应改为editorial。 editor的意思是“编辑”,根据题意改为名词editorial(社论)。 DC5^k[m  
n@`:"j%s_  
 s_p\ bl.  
例:For centuries, music have played acoustical guitars, 9c}mAg4  
         A >,&@j,?']  
  which produce sound from the vibration of the strings. |BC/ERms  
   B      C      D p:/#nmC<  
分析:A错,应改为musicians。music是抽象名词,意为“音乐”,不能表示复数要领显然应改为musicians(音乐家)。 ?4^ 8C4

(六) 只能用副词+数量词+名词;不能用形容词 s[}4Q|s%
