考博语法攻略大全

改错题常考要点 _Dym{!t  
一、代词 fQL"O}Z  
代词中主要讲解六个问题 @) s,{F  
(一) 掌握代词的几种格 2kdC]|H2?  
  主格、宾格、所有格 PH?#)l D  
  名词前面用代词来修饰,只能用所有格(my books) B*4}GPQ  
_@ *+~9%8p  
(二) 反身代词 u}!@ ,/)  
当主语和宾语表示同一事物时,宾语使用反身代词。 S/Fkw4%  
  He killed himself. (他自杀了) 8<.C3m 6h  
  He killed him. (他杀了他) e&>;*$)  
.pfP7 weQ  
例:Researchers at the University of Colorado are investigating  R  zf  
    A                 B    F%i^XA]a*  
  a series of indicators that could help A|L8P  
             C      HPb]Zj  
  themselves to predict earthquakes. Hir Fl  
    D  EI_  
分析:D错,应改为them。如果用反身代词themselves,指代对象是从句主语that(即名词indicators),这显然是错误的。从句意来看,help的宾语应该是主句主语researchers,故应用代词宾格而不是反身代词。注意C并没有错,情态动词could 比can语气弱,表示较小的可能性。 TjQvAkT  
Indicator为征兆,这些征兆帮助他们来预言地震。主语是征兆,后面指研究者,不是同一个事物 io#&o;M<  
Si_%Rr&jW  
(三) 代词的单复数,代词的性别 ~zSCg|"r  
在考试中如果代词打横线,代词错误的概率是非常高的,因此代词打横线,应该先看代词有没有错。 %^1cyk  
v^zu:Z*  
例:The continental divide refers to an imaginary line in the North American Rockies &v"3*.org@  
  that divides the waters flowing into the Atlantic Ocean from it flowing into the PH> b-n  
     A   B      C          D Qu} W/j|3  
  Pacific. 2gzou|Y  
]d a^xWK  
分析:D错,应改为those。D指代复数名词waters, it是单数,显然是错误的,根据习惯故改为those。注意waters一词并没有错,它指江湖河海中的大片水域,可用复数形式。 *^RmjW1I  
LJOr!rWi  
Water作为水是不可数名词,waters表示水域,通常使用复数形式,作主语谓语动词用复数。 "Kc>dJ@W  
Work作为工作是不可数名词,work作为作品,可数不可数都可以,例如: wKi^C 8Z2  
  Many of his works= much of his work, work都表示作品 I!>\#K  
Ux #x#N  
例:In 1920 the presidential candidate Warren Harding coined HAv{R!*  
                       A   ] )F7)  
  the word“normalcy”to express social and NvHJ3>"%  
             B !2z?YZhu  
   economic conditions they promised the nation. ZR$'u%+g'  
   C       D ?W0)nQU  
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。 rHf&:~   
<c%W")0  
例:Many critics believe that Amy Lwell' s most important /;tPNp{!dw  
        A     zfc3)7  
  work is not poetry, but his biography, John k51Eyy50(  
   B        C      ,(.MmP`  
  Keats, published the year of her death.  ?x+Z)`w_  
      D *dvDap|8W  
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. v3GwD0 0  
/sr2mt-Q  
eL4NB$Fb  
(四) Who和which的区别 t=*@yQ nB  
which指代事物或者动物,who指代人 TLd`1Ac  
who/whom son往往要改为whose son, whose可以指代事物 ?-tVSRKQ  
Cn>ADWpT&  
例:The human body contains more than six hundred muscles who ]c&<zeX,  
              A            B [HN|\afz  
  account for approximately forty percent of the body weight. 8)kLV_+%  
   C                  D 4Q IE8f Y  
分析:B错,应改为which或that。先行词不是指人,而是指物,关系代词不能用who,故改为which或that。 _:+ KMR  
人体前面加定冠词the, account for 占有多大的比例,解释说明 DAwqo.m  
sHcTd>xS  
(五) that和which的区别 ~>0qZ{3J_  
介词后面使用which, 而不用that, in that除外 bsd99-_(4  
kNT}dv]<  
例:When television was first introduced, the extent to that it ~+<olss_  
              A        B n!6Z]\8~$  
  would affect society could not have been foreseen. '+ xu#R  
      C              D 8vuCc=  
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 }|B=h  
En&5)c+js4  
(六) 定语从句的特殊省略 BYY RoE[P  
Reason后面有定语从句,中间往往省略why, p'sc0@}_O  
Time后面有定语从句,中间往往省略when v+e|o:o#  
   I do remember the time I heard the sweetest voice in the wild world. Bm\qxQ  
way后面有定语从句,中间省略了in which \v6 M:KR5/  
]I/Vbs  
例:Research on pain has been neglected, although the mainly mR8W]'gl.L  
              A         B   BZb]SoAL  
  reason people take medicine is to relieve pain. !GW ,\y  
         C      D Z+pom7A"E  
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 CC;! <km  
YpUp@/"  
例:Commercial expansion from city to suburb has  $|$e%   
  affected the way people in the United States----. r}u%#G+K,  
   (A) living and working M HL("v(@B  
   (B) they live and work iq hOi|!  
   (C) live and work C K_(b"  
   (D) to live and to work 5 cK@WE:  
分析:选择C, the way people....影响了人们生活和工作的方式。 'SLE;_TD  
Aa?I8sbc  
二、介词 )'Wb&A'  
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。 ;Qi }{;+  
PN$ .X"D8  
(一) 介词搭配 BpO9As 1um  
#JA}3]  
例:The teeth in the upper jaw function together those o2-@o= F  
    A         B   C      b'ml=a#i 0  
  in the lower jaw to cut, tear, and grind food. {dPgf  
                D oUx[+Gnv  
分析:和…一起,应该为together with,C错 %Y4e9T".  
U},=LsDsW4  
例:The Allegheny Mountain range is rich of coal. ZX b}91rzt  
A       B     C  D :9l51oE7  
分析:B错改为be rich in ,`td@Y  
v_PdOp[ k  
例:The rotation of the Earth on its axis is responsible to the BzpP7ZWV  
    A         B      C Qq0l* )mX  
  alternation of periods of light and darkness. *i$ePVU  
             D yy2Ie  
分析:C错,应改为responsible for。形容词responsible后接名词作宾语时要加介词for。 {bF1\S]2  
}xn_6  
ned2lC&'d>  
(二) 最重要的两个介词 NWmtwS+@  
1、介词of 多余或者遗漏 Aj"7q  
例:Mosquitoes usually lay eggs, singly or in batches, on top stagnant water. ,<ya@Fi{  
          A      B  C     D Zu<]bv  
分析:D错,应改为top of stagnant。on top of …是因定表达法,意为“在…上面”。 ,[48Mspp  
),@f6](  
例:Christopher Plummer is a Canadian actor who has ['X[qn  
                 A  B     sDiHXDI_m  
  starred in stage, television, and film productions on h:qHR] 8dZ  
      C Ruh)^g  
  both sides the Atlantic Ocean. p5 ]_}I`+2  
      D oJ;rc{n-  
分析:D错,应改为sides of the。 sides为名词,the Atlantic Ocean也是名词,中间明显少了一个介词。 )3?rXsSR  
B0mLI%B  
2、介词by PjqeE,5  
一种情况表示被动,be+过去分词+by ?{J!#`tfV  
另一种表示通过……的方式, by doing }VRv sZ  
例:The ceremony of marriage in the United States lxb8xY  
    A         B       H30OUrD  
   can be performed from a justice of the peace. z%"Ai)W/{  
   C     D LPE)  
分析:D错,应改为performed by。谓语动词是被动式,performed的动作执行者应该由介词by来引导。 delf ]  
f{Qp  
例:Along the east coast ,American Indian women's councils K}x/ BhE+  
   A                      tE hr  
   could veto a declaration of war at refusing to `bP?o  
     B    C       D xks?y.wA  
   supply moccasins and field rations. Lx+`<<_dJ  
分析:D错,应改为by refusing。通过拒绝提供鞋子和粮食,表示通过某种方式做某事要用介词by,故将at refusing 改为by refusing。 IcoowZZ   
>!BFt$sd  
例:Algebra is the branch of mathematics concerned with |>utWT]S  
        A                >[3X]n,0  
  operations on sets of numbers or other elements dtW0\^ .L  
        B          C   ' iQ9hQjD  
  that are often represented at symbols. yq*JdTF  
              D " 3y}F  
分析:D错,应改为by。动作的发出者应该用介词by来引导。 `jW 4H$D  
三、谓语动词 76MsrOv55  
(一) 谓语动词的主谓一致 .uDM_ 34  
①、主谓分割原则 1P5LH 5  
例1:To the citizens of the United States, the bald eagle, =R9*;6?N  
     A     SfDQ;1?  
   America's national bird, symbolize strength and freedom. &z ksRX  
        B      C      D dQ6GhS ~  
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。 &7][@v  
j`9Nwa  
②、与后者一致原则 .eTk=i[N-  
not…but, 强调but后面的名词, !aeNq82  
not only…but also +S0u=u65  
)Pa*+ew7  
H5p5S\g-)  
③、与前者一致原则 Bm<^rhJ9  
名词+with/together with/as well as/including+复数名词,谓语用is, J0qXtr%h\  
中心词在前面,谓语动词应该与前面的名词保持一致 5G oK"F0i  
例:The athlete, together with his coach and #S *pD?VZ  
     A      B  C     x\]z j!  
  several relatives, are traveling to the Olympic Games. `:3&@.{T(  
         D qOgtGN}k  
分析:D错,与谓语动词与the athlete 保持一致,改为is 4@/z  
N6 BNzN}-P  
④、就近原则 ,5kvn   
or, either…or, neither…nor, oB}K[3uB:t  
单数名词+or+复数名词+are ^\{J5  
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 /Mx.:.A&$  
所以注意一点: 如果是陈述句,靠后面近,用复数 #!1IP~  
        如果是疑问句,靠前面近,用单数 uDI}R]8~  
59~FpjJ  
例:The structure or behavior of many protozoans are <L2GUX36#  
        A      B        {YBl:r Mz  
  amazingly complex for single-celled animals. k!9=  
    C              D O&52o]k5l  
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。 MyqiBGTb  
p&QmIX]BZ  
⑤定语从句主语就近原则 C|9[Al  
There are five apples that are red. ' #KA+?@  
apples是复数,因此从句谓语动词是复数。 gINwvzW{  
Dl&PL  
例:A rocket burns propellant rapidly and most rockets f~U #z7  
      A            YK7\D:  
  carry a supply that last just a few seconds. V*>73I  
   B   C    D 89db5Dx  
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。 8V,"Id][  
T0s35z9  
⑥the +形容词主谓一致 Oe/73| >U  
The rich are not always happier than the poor. k"5` :qL  
The rich 表示一类人,应该用复数 I7A7X*  
ypgliq(  
⑦、倒装句的主谓一致 )CFk`57U  
改错题倒装句的主谓一致一般考两种情况: J1nXAh)J  
a. there be 句型 %Fs*#S  
there be+名词+名词,那么最近的名词决定其形式 i[o&z$JO  
b. between/ among 放在句首+be+名词,名词其实是主语,所以be和名词保持一致 r^fxyN2V  
/L)?> tg  
例:There are no known society in which left-handed people predominate. )o86lH"z  
   A     B      C    D    -hQ96S8  
分析:there be 句型由最近的名词决定其形式,society当然用单数,A错,there are 改为there is 5<!o{)I  
|GJBwrL^0  
+[>y O _}  
例:Between the foothills of the Andes and the Pacific A J<iM)l|  
             A     B    Gs^(YGtU  
  Ocean are a dry coastal strip averaging about 30 Bjurmo  
     C          =|^X$H  
  miles in width. BT&rp%NO6l  
     D  <+ -V5O^  
分析:倒装句,are改为is ~l;yr @  
( K^YD K  
例:Among the favorite attractions at the National Air and V;M3z9xd  
   A    B       C         7~nIaT  
  Space Museum in Washington D.C. are the film VC/R)%@%  
                    D }".\ 4B$n  
  presented on the five-story-tall screen. ?y+\v'3v  
分析:D错,应改为films , 主语实际上是名词,应该与谓语动词保持一致。 P}ehNt*($  
3N(8| wh  
⑧、百分比结构的主谓一致 SS >:Sw  
fifty percent of + 名词 i n[n A a  
one percent of + 名词 [d!Af4  
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: FCsyKdM  
  one percent of my students + are v1`bDS?*Q  
  fifty percent of my time is spent on working. O JZ!|J8?  
e_fg s>o`(  
这里要强调两个结构 7H8GkuO  
half of =fifty percent ucIVVT(u  
most of + 可数名词 + are 8cYuzt]..  
most of + 不可数名词+ is $bF`PGR_  
>=Rd3dgDG  
例:Nearly half of the ancient meteor craters has been }w|=c >'_}  
   A       B         C   |q1b8A\  
  found in central and eastern Canada. KD[)O7hYC  
           D %8bFQNd  
分析:C错,应改为have been。介词of的宾语为复数名词短语,作主语的中心词half当然表复数,相应的谓语动词应为复数形式。 >tE,8  
JCCx 5  
例:Approximately fifty percent of the package utilized z9OMC$,V  
                 A   B  $S"zxEJJ Y  
  in the United States are for foods and beverages. tA;ZW2$#  
              C     D .{-iq(3  
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。 ( S C7m /  
r`mzsO-'  
(二) 谓语动词的时态 A61-AwvF8-  
①、主要考察时间状语 0*]<RM  
<+mO$0h"r  
例 The metal aluminum has been first isolated early in the nineteenth century. %oSfL;W7  
   A        B  C     D //4p1^%  
B4M'Er{v  
分析:Metal, aluminum同位语,in the nineteenth century为明显表示过去时间的状语, 因此应该用过去时态,把has been改为was Cbf,X[u  
s>"WQ|;6  
st1M.}  
②、For和since的区别 :`!mCW`Q-  
区别一:For 后面使用时间段,since 后面使用时间点 J[_?>YJ  
区别二:Since 只能用在现在完成时态,For 最主要用在现在完成时和一般过去时 vp9E}ga  
  I has been a teacher for three years. *< SU_dAh  
  I has been a teacher since 1996. 3`C3+  
  I was a teacher for three years. 这种表达可以,for three years表示一段时间,was 表示过去做了三年,现在不是老师了 y|2g"J  
aV0;WH_3  
例: Since 1921 the budget of the United States became H603L|4  
   A      B              ," HpV  
  the primary responsibility of the president. ROI$;B(  
     C    D @tU>~y{E  
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。 GQc%OQc\  
^LAS9K1.  
例:Adella Prentiss Hrghes served as manager of Yh!\:9@(  
             A  B  C   &b#NF1Q.  
  the Cleveland Orchestra since fifteen years. {UjIxV(J  
            D Q0oDl8~  
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。 'XjHB!!hU  
I[ YfF  
8B(Q7Qj  
52. In general, prawns lived in shallow coastal waters or in streams.  >5YYij5Aj  
   A       B        C     D (>/Dw|,m  
自然现象和客观事实用一般现在时态,live ~o\]K  
-Z#]_C{Y-)  
(三) 谓语的语态 ;R-Q,aCM}  
语态主要表示是主动语态还是被动语态。 X$Qi[=L  
有四组动词是改错题中常考的: iS^^Z ZyR  
①、prove 6(Rq R  
My advice proved to be wrong. 我的建议被证明是错的 ` G/QJH{I  
尽管是被证明,但习惯上用主动; % w/1Uo24  
|kRx[UL  
例:A majority of the reports received from people claiming Sv[_BP\^h  
                      A   Op)R3qt{  
  to have seen the legendary Loch Ness Monster have proven to be 5L'@WB|{4u  
    B                  C SX94,5 _Q  
  mistakes, misconceptions, or they were being tricked. J*kzJ{vwy*  
                  D oZ>]8vw  
分析:D错,应改为tricks。并列连词 or在此连接名词,如果把D理解为并列句,不仅时态不对,语义也有问题,故将整个句子改为名词。have proven to be是正确的。 CX(yrP6;  
x[<#mt  
>WG91b<Xq  
②、Locate,Situate GAe_Z( T  
这两个词可以用作主动,表示把…放置在…地方;确定…的位置 "VhrsVT  
  Bats locate obstacles.蝙蝠确定障碍物的位置 [}Yci:P_ +  
这两个词也可以用作被动 Q14;G<l-  
  My school was located near the river. ;C@^wI  
区分locate的主动和被动比较难,但是有一个技巧存在:locate如果用作主动,后面必须跟宾语 Ptxc9~k  
例:The center of gravity of the human body ---- behind the hip joint. g{.@|;d <p  
   (A)locates 8c' -eT"  
   (B)locating :'Kx?Es   
   (C)to locate m,"tdVo.  
   (D)is located ;-wPXXR  
分析:空格处显然缺谓语动词,故首先排除不能作谓语的B和C。动词locate后面没有宾语,所以用作被动,表示“位于”,所以D为正确选项。 Tp.iRFFkP  
(B4 A$t  
③、表示需要概念的动词 'wHkE/ 83  
need, want, require等 k:yu2dQh  
z:? <aT  
My watch needed repairing nqW:P$  
My watch needed to be repaired. Ol^EQLO  
QE6-(/  
④、表示人的情感的动词 ?a_q!,8:  
move, annoy, surprise, please等 LU=)\U@Q  
#GJh:#tt^  
He is so moving.  他令人感到感动。 %HS!^j3C%  
He is greatly moved. 他感到非常感动。 VZ!$'??  
_ o3}Ly}  
主动和被动技巧总结: kV<)>Gs  
如果句子中有一个“过去分词+by”, 如果断定它是谓语的话,前面必然有be动词 |}Lgo"cTC  
c W%O-  
例:The Tennessee Valley Authority has chartered by the w#b2iE+Bw  
                 A      nJ@hzK.  
  United States Congress in 1933 to construct dams, | Ylk`<  
                 B w\4m -Z{  
  power structures, and flood-control works along xo+z[OIlF  
                    C &d;$k  
  the Tennessee River and its tributary streams. a"4 6_>  
                D Puh&F< B  
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。 K@hUif|([  
,:{+ H  
四、非谓语动词 xnO lV  
&o.SmkJI  
(一) 分词 m8' 1@1d|  
现在分词和过去分词的区别 ARo5 Ss{  
①、用于句首作状语,现在分词表示主动,过去分词表示被动 ]^<~[QK_C  
t T:yvU@a  
例:Won its war for independence in 1783, the United States then A@r,A?(  
   A Tkf !Y?  
  struggled to establish its own economic and financial system. 7m:,-xp  
     B      C            D ],|B4\b;  
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 A\Gw+l<h,  
lla96\R  
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 nc)`ISI  
例:In the nineteenth century the Mohave Indians lived in 7O#>N}|  
      A               B   ":ycyN@g  
  the Northern Hemisphere grew their crops on river bottom lands. Viw3 /K  
               C         D *Q?HaG|S  
分析:B错,生活在什么地方的人,人生活是主动,因此改为living CS49M  
\\JXY*DA:+  
F ReK  
一些动词后面必须用doing 9`AQsZ2  
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。 Pl4d(2 7  
 mind, finish, enjoy, celebrate, ; ] !  
 advocate, suggest 2Z~o frj  
 delay, quit q`hg@uwA{`  
 forgive(原谅),tolerate, {YFru6$  
 avoid, escape(逃避) 4.TG&IQ nN  
 spend+名词+doing; DNPK1e3a{  
 have trouble/difficult/a problem/ +doing K9R[ oB]b  
3-'|hb  
例:Long before the dawn of recorded history, humans celebrated to harvest their `0D+ x  
   A     B    C              D 6c:$[owC  
  crops. 0U'r ia:$  
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。 R[QE:#hT

五、句子的结构 =0t<:-?.-  
句子的结构主要考查四个出题方向。 t1`.M$  
~Z` Cu~7  
(一) 主语的重复 *Z8qd{.$q  
名词+代词+谓语,这个代词永远是重复的主语,永远是错的 P9 w);jp;  
例:Woodrow Wilson he was an idealist who refused to make any YMn*i<m  
          A      B      KPjC<9sby  
  compromises concerning the establishment of the +R8G*2  
          C          D prEI9/d"  
  League of Nations. BaVooN~C  
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 H-,p.$3}  
A prolific writer, Woodrow Wilson T@jv0/(+  
FLo`EE":O(  
Q h{P>}  
例:Two unique features of the Arctic they are !]3kFWs  
        A        B  K&VMhMVb  
  lack of precipitation and permanently frozen ground. x1h&`QUP  
    C         D |It&1fz}  
分析:选项B中的they和前面的主语two unique features重复 3bRW]mP8  
#-i#mbZ e  
(二)谓语的重复 | |L^yI~_d  
完整的句子后面又多了一个谓语,往往改为定语从句 nAC>']K4$  
388vdF  
例:A paragraph is a portion of a text consists of  6zi 5#23  
    A            B    d}y ")q|F  
  one or more sentences related to the same idea. G8zbb  
         C   D aL*}@|JL"  
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。 R$p(5>#\5  
6RG63+G  
(三)谓语的缺少 VsJKxa4  
例:Most mammals to maintain a relatively constant body  |e<$  
          A     B    Gr>CdB>~+  
  temperature, regardless of what the air temperature might be. xYZ,.  
         C               D dBwoAq`'  
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。 q65]bs4M  
-&Q+x,.%  
(四)主句的重复 G3 |x%/Fbp  
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 +$Y*1{hyOo  
8A5/jqnqt  
@lq)L  
例:Salmon spend most of their adult lives in salt water, despite cU-A1W  
      A         B        C   Y9gw ('\w  
  they return to their freshwater birthplaces to spawn and die. fs:yx'mxV  
     D hs5>Gx  
分析:C错,应改为though。despite是介词,后面一般接名词作宾语,而在句中它后面却跟着一个完整的句子,所以改为连词though。 [2YPV\=  
PxQQfI>  
例:Solar eclipses occur during the Moon's shadow '9=b@SaAj  
        A   B       a]P w:lT  
  sweeps across the face of the Earth. * nFzfV  
      C    D BU4IN$d0Po  
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。 e&2,cQRFV  
E .28G2&  
例:Even many early leaders of the United States have provided ]jY^*o[  
   A                     B  o2=):2x r{  
  names for towns, only George Washington gS'7:UH,  
      C IC5QH<.$C  
  is remembered in the name of a state. .d r Y  
          D 4I$Y"|_e  
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。 .ARM~{q6)@  
六、比较级和最高级 j dLu\=@z  
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 u z7|!G!43  
oe.Jm#?2.  
(一)    比较级或最高级形式上的重复 :IBP "  
例:The most easiest process for mining gold is panning, which 2J{vfF  
      A               s+v9H10R  
  involves using a circular dish with a small pocket at the bottom. e"wz b< b  
     B       C           D \Cu=Le^  
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 1;1;-4k7I  
['Lo8 [  
(二)比较级和最高级之间的混用 b@&uwSv  
例:The greenest and plentifulest leaves are the leaves of grasses. }~|`h1JF  
     A      B     C  D ,*U-o}{8C?  
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。 g_IcF><F  
Jw@X5-(Cp  
例:The more fearsome of all the animals in the Western Hemisphere -&`_bf%M  
     A       B     C   D i+mU(/l2{  
  is the grizzly bear. y>x"/jzF#  
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。 |f @A-d X  
']eN4H&=?}  
^7/v[J<<  
(三)比较词than的前面一定要有比较级 \Db;7wh  
改错题中,通常会看见than前面有一个原级  mjP  
z^`4n_(Ygu  
例:Film directors can take far great liberties in dealing with Z2m^yRQ(  
   A           B  |(*btdqy3  
  concepts of time and space than stage directors can. (E@;~7L  
   C                 D Bo8f52|  
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。 :*,!gf  
1="]'!2Is  
(四)在as…as以及否定not so…as, not as…as的中间使用形容词原级 VnSO>O  
as sweeter as, 这是不对的,应改为as sweet as hNZ_= <D!  
!PGCoI  
(五)the 和比较级最高级的关系 JUA%l  
①、比较级前面可以出现the, 修饰后面的名词 Cj3Xp~  
the taller boy fJ.=,9:<  
/<LjD  
②、副词的最高级加不加the均可以 cJq {;~   
例:Although flies live longest in cool temperatures, it breed q1 q~%+Jy  
          A            B #S/~1{   
  prolifically when temperatures are warm, food is uGXvP(Pg'  
  abundant, and humidity is moderate.  E JC}"%h  
    C          D DL~! ^fx  
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 W%ix|R^2]  
bt=D<YZk  
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 M^ WoV }'  
例:Of all the Native Americans in the United States, i=b'_SZ '  
  A  B         C     `O3#/1+  
  the Navajos form largest group. 1iR\M4?Frf  
         D !lEV^SQJs  
分析:D错,应改为form the largest。形容词最高级前面要加定冠词。 ZU B]qzmK  
<LBCu;  
陷阱1, earliest, 有两种可能, Bt:M^b^   
一种可能是early的最高级,最早的语言,the earliest language 8sDw:wTC  
    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 P!9-!+F"  
u8A,f}D 3  
例:The belief in fairies have existed from earliest times, and the literature of many O>rz+8T  
            A      B         C NODE`VFu  
  countries includes tales of fairies and their relationship to humans. mrE> o !  
            D ri"=)]  
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。 w{;bvq%lY  
dXt@x8E  
陷阱2,如果最高级前面有所有格的话,不用加the Pvkr$ou  
例如:my best friends +)( "!@  
6 ;\>,  
例:Salt Lake City, Utah's capital and largest city, is industrial % kBrxf  
            A    B     C <3k9 y^0  
  and banking center. ,+n {xI2  
        D ,`ehR6b  
分析:C错,应改为is an industrial center。center为可数名词,它的修饰词前面应有不定冠词。 M|z4Dy  
Utah's largest city, 题目中其实是省略了Utah's。 viS7+E|O  
Q?m= a0g  
F*B^#AZg  
例:Faults in the Earth's crust are most evidently in sedimentary ~|wh/]{b9  
                 A         ",E$}= ,Z  
  formations, where they interrupt previously continuous layers. $kQQdF  
    B   C     D < M3&\  
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 -S $Y0FDV  
eNt1P`2[  
七、平行结构 ? i| LO  
改错题考的最多的一个方向便是平行结构 nfr..4,:  
;&RHc#1F  
M059"X="  
(一) 对等连接词 +u7nx  
一共有三类连接平行结构的词 V@ph.)z  
单一式: and, or ,but AUkePp78  
相关式: both…and, not … but, G-T2b,J [  
     either …or, neither…nor 3)py|W%X $  
     the same…as;as…as, not so…as, not as…as '%A*Z,f

     not only…but also(also可以省略),Not only +主谓,also &uTK@ G+  
     not only…but also(also可以省略)+as well, o>4GtvA*  
<NX6m|DD  
短语式: as well as ZNbb8v  
     rather than (而不是) NA8$G|.?  
     other than (除…之外) SE!0f&  
     instead of (代替) > 1 &_-  
{d,~=s0T  
考试的方式往往是搭配中有一个单词是对的,另一个单词却不对 uzUZuJ  
例:John lived in New York since 1960 to 1975,  ?wS/KEl=O  
       A     B   |b: 91l  
  but he is now living in Detroit. 8klu*  
       C   D o]*#|4-  
分析:B错,应改为from。“从某年到某年”要用“from…to…”这个表达法,不能用since …to…。 1 9C=' TMS  
RBzBR)@5   
例:Even as he wrote copiously on so diverse topics [6Gb@jG  
       A         B v81H!c.*  
  as education ,politics ,and religion ,Lewis Mumford zcNv T  
  remained active in city and regional planning. >A;9Ee"&  
          C    D  ]1 OZY@  
分析:B错, 改为such diverse topics as, 出现as, 往往要注意前面一半 fgSe]q//  
(二)平行的内容 ]2P*Z6Az  
第一、引导词性的平行,词性的平行本质上是语法作用的平行 .-g++f(_i  
例:Photoperiodism is the functional or behavioral response of \{ui{8+G  
             A         B   U &\8~h  
  an organism to changes in duration of daily, seasonally, %kJ_o*"  
         C            D 4>&%N\$*  
  or yearly periods of light and darkness. _#/zH~V%  
分析:D错,应改为seasonal。在daily, seasonally和yearly三个并列的词中,daily和yearly是形容词,seasonally是副词,故改为形容词seasonal,共同修饰名词periods,三个形容词的平行,词性平行  hVB^:  
vA*Ud;%R  
'bXm,Ed  
第二、名词单复数的平行 A%pBvULH  
但是如果既有可数名词,又有不可数名词,可以不平行 (hn@+hc  
Iu`xe  
例:The main advertising media include direct mail, 02_%a1g  
  A     B          C   Wa {>R2h\  
  radio, television, magazines, and newspaper. &K_"5.7-56  
                 D   2%'iTXF  
分析:D错,应改为newspapers。newspaper为可数名词,在没有任何前置修饰语的情况下一般用复数形式,并且和前面的magazine平行,而mail, radio, television则是不可数名词。 x05yU  
%/o8-N|_[  
例:The Canadian province of Newfoundland has a rocky coast, a moisture climate, w{t2Oo6Q0+  
                   A         B 9oK#n'hjb  
  and probably the best cod-fishing areas in the world. u2SnL$A7  
      C          D ]e'Ol$3U9=  
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 s\6kXR  
~L G).  
第三、时态的平行 pFLR!/J  
例:The poet Marianne Moore was initially associated $W 46!U3  
                A     MjAF&bD^  
  with the imagist movement , but later develops $DmWK_A  
                   B (=d%Bn$6b  
  her own thyme patterns and verse forms.  m/)Wn  
          C    D z:hY{/-  
分析:B错,应改为developed。句中前半部分谓语为过去时,与之并列的谓语也应用过去时。 +1Ha,O k  
2},|RQETy  
例:Because the papaya grows readily from seed , ----- &wbe^Wp  
  spread from its home in Central America and .u3!%{/v(c  
  now grows throughout the tropics. w` (EW>i  
   (A) to be    (B) it   qm-G=EX  
   (C) the     (D) its }JXAG/<  
分析:正确答案为(B)。空格前是原因状语从句,后面紧接着是谓语动词,空格处明显缺主句主语。四个选项中只有B能单独作主语。注意spread是过去式,没有数的变化,因为这一动作明显发生在过去时间。spread 和grows为什么时态可以不平行呢? 8}3dwr;-  
原来它在Central America 的家乡传播,现在在整个地方传播,now只修饰后面的grow sT"U}  
 `)`J  
例:Ducks have been domesticated for many centuries ----  =,q,W$-  
  commercially for their meat and eggs. ozZW7dveU  
   (A) raised   (B) and are raised TFbMrIF  
   (C) raised as  (D) are raised sW[8f Z71  
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)。 Pa%;[hbn  
9NTBdo%u  
第四、排列位置的平行 q -%;~LF  
例:---the surface of metal, but also weakens it. ]iewukB4  
   (A) Not only does rust corrode NIcPjo  
   (B) Not only rust corrodes  hnM?wn  
   (C) Rust, which not only corrodes vA rM.Bu>b  
   (D) Rust not only corrodes 6eSc`t&  
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。 p\]Mf#B  
8RJXY:%  
对于not only, but also的用法有以下几种: 4,CQJ  
 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。 gs)wQgJ[  
 2、Not only +主谓,but also+主谓,正确 [5 Mt,skC:  
 3、Not only +主语+谓语,but also+谓语,错误 ?-CZJr  
^&oa\7<'  
八、词序的颠倒 \M~M  
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 xc[Lb aBG  
(一) 先说形容词,再说名词 RIBj9kd  
例:The Medal of Honor is the highest award military for courage s&MfC\  
              A    B        -oo&8  
  that can be given to any individual in the United States. QAYhAOS|e  
      C       D    qdoJIP{  
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。 +g8wc(<ik  
@vWf-\  
f`w$KVZ1!w  
(二) 副词+形容词+名词 <fq?{z  
例:Certain types of computers work properly only qMT7g LB'1  
          A      B     8s6~l.v  
  in environments with controlled precisely temperatures. 'f0*~Wq|  
    C         D :7&#ej6  
分析:D错,应改为precisely controlled,精确的被控制的温度。controlled为过去分词用作形容词,修饰它的副词应放在其前面,它自己则要紧挨着被修饰的名词。 0{bGVLp  
Qhlgu!  
' V";"Ei  
(三)主语系动词, 系动词 + 表语 :#8#tLv  
Sc Uh -y_  
例:During the 1600's skilled shoemakers scarce were Bbuy y  
          A   B     C   w'[lIEP 2$  
  in what is now the United States. _^cDB1I ?  
    D &|('z\k  
分析:C错,应改为were scarce。表语应该放在系动词后面。 4qq+7B  
e(7F| G*  
所有的系动词分为三大类: AF5.)Y@.  
第一种:表示保持某种状态, mY9^W 2:  
    is, remain, keep, stay, 3=w$1.B d

enough修饰形容词或副词时,一般放在形容词或副词后面。 1fBj21zG  
例: The eruptions of Mt. St. Helens were enough severe 2QwdDKMS_  
    A               B     ETk4I "  
   to cause numerous deaths. J})G l  
        C   D  QkbXm[K.Z  
分析:B错,应改为sever enough。severe是形容词, enough放在severe后面。 2pR+2p`

九、词性的混用 !1 :%!7  
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。 Rlc$2y@pU

(一)做表语时形容词和副词的混用 5 [{l9  
做表语永远用形容词,绝对不能用副词; O_%X>Q9  
jWHv9XtW  
例:Giant pandas, which inhabit restricted areas of high eUP.:(E  
          A        B      w|$i<OIi)  
  mountain bamboo forests, are rarely today and f' |JLhs  
              C U .?N  
  when they are in captivity they breed poorly. I8*_\Ez  
          D fBtTJ+51}  
分析:错,应改为are rare。rarely为副词,不能作表语,故改为形容词rare(罕见的,稀少的) G 3))3]  
* E$&  
xgsEJE  
(二)加宾语时名词和动名词的混用 %K0 H?^.  
后面加宾语当然要用动名词 FbH 1yz  
例:Tilling means preparation the soil to plant the seeds QD6<sw@]P  
         A       B      p0c*)_a*  
  and keeping the soil in the best condition to R_? Q`+X  
          C        fpd4 v|(  
  help the crop grow until it is ready3 for harvesting. ?T.'  q  
            D jVA|Vi_2  
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。 !vd(WKq  
FU]jI[  
例:Langston Hughes, a prolific writer of the 1920's, e`]x?t<U4/  
            A       [S Jx\Os  
   was concerned with the depicting the experience of 94uAt&&b(  
      B      C Fa ]|Y  
   urban Black people in the United States. yRd[ $p  
   D 4%refqWK  
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。 Q)mYy

(三)表示时间时,状语从句连接词和近义的介词混用 -l(G"]tRB  
表示时间有两种可能, ]LbFh5;s  
一种是状语从句,由when and while引导,后面加句子 5rX_85]  
另一种是由介词引导,如during,后面加名词, kleE\ 8_  
考试中往往就利用这个特点,总是给出相反的情况 n{*A<-v L  
Y|X!da/  
例:Balloon observations for military intelligence >;s!X(6 b  
       A     B     0bz':M#k &  
  were made while the American Civil War. ka c -@  
   C    D RKb{QAK!v  
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。 F2) \%HR  
D~Rv"Hh  
例:Some of the most celebrated publicity stunts while the `ElJL{Rn  
   A      B           C    /ka "YU  
  history of radio were associated with Gracie Allen. 7W.z 8>p  
          D JTcE{i  
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。 ?910ki_

!QsmT3   
(四)对等连接词和近义的副词混用 o>^ @s4t  
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。 !*!i&0QC~R  
@W.0YU0|J  
例:Mary McDowell shared Jane Addam's interest in social &Db'}Y?x]  
                   A     =`+c}i?  
  work also was a loyal supporter of the League of Nations. {fxytiH8  
     B   C    D [P3 Z"&  
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。 {C'9?4&  
91oAg[@4G  
例:Paper is strong under tension instead crumples 7J|e L yj  
   A        B   C      f^[u70c82  
  easily under the stress of compression. 4<A+Tf  
   D &eFv~9  
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 .B_a3K4'{^

(五)表示人的名词和表示事物的词混用 en8l:INX  
^~DClZ  
例:An editor is customarily a brief newspaper or magazine s}Q*zy  
    A         B 8?[#\KgH1  
  article that gives personal comments on current events. Yg! xlrxA  
          C            D v0W/7?D  
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)。 Y/`*t(/5  
WXX08"  
(I ~r~5^  
例:For centuries, music have played acoustical guitars, 7rjS.  
         A (E<QA  
  which produce sound from the vibration of the strings. 822jZ sb  
   B      C      D 4qg] oiT  
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)。 {f[ X)  
nhI1`l&  
(六) 只能用副词+数量词+名词;不能用形容词 t_{rKb,  
nearly two hundred students, 这里nearly修饰的是200; (7?jjH^4
