填空题常考结构 .j-IX1Sa
L =8rH5
一、主句单一原则 -e8}Pm
"
任何一个句子中只可能有一个主句。 PK"c4>q
做题时考生需要首先判断原题中已经给出的句子结构,如果已经有一个主句,那么就绝对不能够再出现另一个主句,除非中间有连接词进行联系。 3JVK

(A) They occur where they are l~M_S<4n
(B) Occuring where f{FDuIln
(C) Where they occur zF`c8Tsx])
(D) Where do they occur %wSj%>&-R
分析:空格后面是一个主句,(A)为带有从句的主句,空格后又是主句,有两个主句一定错。 K=,F#kn
C为地点状语从句,正确(劳动歌曲发生的地方)。 w.0qp)}

例2: --Indiana, is in a rich farming and dairy area, it is primarily a diversified industrial center ?! `=X>5
(A) Fort Wayne )'4k|@8|
(B) Although Fort Wayne uxzze~_+C
(C) For wayne is in 19j+lCSvH
(D) Fort Wayne, in YWxc-fPZ
分析:空格后有两个谓语动词但中间没有连接词,由此可知,最后一句话是一个主句,空格处应该有从句引导词,四个选项中只有(B)中although能引导从句,故选(B)。 G^`1]?

二、谓语动词专一原则 pb=cBZ$
任何一个句子只可能存在一个谓语动词。 7K5P8N
,
句子中不可能没有谓语动词,也不能多于一个谓语动词(除非中间存在连接词)。 r9ww.PpNk#

<i@
(A) covers w18y}mS"H
(B) covers it Z>^pCc\lH
(C) which covers ti<;7Yb
(D) which it covers U8G%YGMG.4
分析:空格后的deals with 是谓语动词,A, B是谓语形式, 和deals with 之间没有连接词,可先排除; D 中的it多余,因为在定语从句中which已经作了主语;C构成正确的定语从句 ]TyisaT

例2:In copper engravings and etchings, -----caused dH^ <t,v

(A) the impression is xSBc-u#< G
(B) if the impression is dF~8XYo
(C) impressions HX
6Ma{vBk
(D) the impression +r<0zh,n.
分析:题目中的is是谓语,A,B中是谓语重复。C为复数名词,与后面的谓语动词is的数不一致,故也排除。因此选择D,caused.... 修饰impression p+Y>F\r&w
三、平行结构 j8sH#b7Z
技巧:如果填空题中空格的后面有and, 或者and后面有空格,那么这道题目一定是考察平行结构。 P(K>=O
填空题中平行结构出现的形式是: hsw9(D>jp
A and B, gc?#pP
A , B, and C kn/Ao}J74z
d%0~c'
D8a
例1:The technique of recording, classifying, and-- lbuA

(A) an enterprise's transactions summary V3ndV-uQE
(B) the summarizing of an enterprise's =2

transactions =ID
2
(C) transactions of an enterprise are T
=2=k&|
summarized {H{X[p8
(D) summarizing the transactions of an }`NU@O#
enterprise SM^-Z|d?
分析:空格的后面是and, 一般考平行结构,空格处缺与前面recording、classifying并列的动名词。 3S&U!
四个选项中只有(D)符合条件,故选(D)。 CV{r5Sye
h/,${,}J
例2:Louis T. Wright, a surgeon, developed `w.AQ?p@
ingenious orthopedic braces, --, and A Z{^o4<q
supervised the first use of Aureomycin on I=!rbF;Z
human patients. mP(kcMT"
(A) treating skull fractures that he pioneered in /QEiMrz@6
(B) pioneered in treating skull fractures oQL59XOT4
(C) which pioneered in treating skull fractures {vE(l'
(D) he was a pioneer in the treatment of skull ehA;i.n
fractures wlPx,UqZ
分析:空格后面是and, 空格处缺少和developed、supervised平行的谓语动词,因此选择(B)。 A?*o0I
s-ZI
^I2\
四、宾语从句结构 NOS>8sy
宾语从句的引导词在前面的主从复合句中已经提到。 ]0r|_)s
这里指出的是填空题中关于宾语从句考的最多的两个结构: p)~lL
state(陈述,表明)+that 1+7GUSIb
indicate(指明,表明)+that u(!&:A9JFd
]LZ`LL'#Y_
例1:The quantum theory states --, such as light, v~/~@jv
is given off and absorbed in tiny definite dr<<! q /
units called quanta or photons. O6]. *25
(A) energy that <A.W 8b7D
(B) that it is energy UgN28YrW
(C) it is energy 1J?dK|% b
(D) that energy _Zc%z@}
分析:空格前的谓语动词states一般接关系连词that引导的宾语从句,故首先排除C。空格后已有谓语动词,空格不应再出现谓语动词,因此D正确。 pZZf[p^s|
; <Km3
|([R'Orm
例2:Studies of the gravity field of the Earth }!TL2e
r_
indicate--yield when unusual weight is *XWq?hi
placed on them. H7[6yh
(A) although its crust and mantle KL'z
XkS
(B) its crust and mantle to nmjm<Bu
(C) that its crust and mantle drq hQ
(D) for its crust and mantle to Yct5V,X^
分析:空格处显然缺谓语动词indicate的宾语。(A)和(D)不能作宾语,可首先排除。(B)使句子结构混乱、语义不清,因此选择(D),构成宾语从句。 =xianQ<lK
五、介词+ which结构 3I 0eW%,
许多同学在选择which还是介词+which上总是不太明白,这里有一个技巧可以告诉大家。 k8]O65t|
“which”后面一定加一个缺主语或者宾语的句子, ~svO*o Wa
因为“which”在这个句子中作了宾语或者主语成分。 m?[5J)eR
"gW7<ilw
“介词+ which”后面则跟一个完整的句子, XUV!C7
因为”介词+which”整个结构在定语从句中作状语。 Cz^Q5F`
:1)DqoAJ
例1:In the United States, a primary election is 9TxyZL
a method ---- voters select the nominees /\Q*MLwD
for public office. ~2_lp^Y
(A) that AKu_~bTk
(B)by which l|/:Ot
(C)is that %"A_!<n@*`
(D)by those
y~<@x.
分析:空格前后都是句子,因此缺从句引导词或连接词,首先排除C和D。 gd^Js1Z
A能够引导从句,但是根据题意,修饰method是不通的。 84&XW
B是介词+which, 引导定语从句,(大选是一种方法,根据这个方法,选民怎么….);正确 >E"9*:.^a
v
vE\
例2: Croquet is a popular lawn game ------ players 1x >iz

wickers. O
%1/r*
(A) when 8TZENRzx-|
(B) which nwM)K
(C) is when Qu~*46?0
(D) in which GH
N3PEJ>
分析:空格前后都是完整的句子,空格处缺定语从句引导词,由此首先排除(A)和(C)。但是到底是选择B还是D,则看从句,从句是完整的句子,那么一定选择D, 关系代词which 前应该有介词。 ;6DnId2Zh
[>w%CY<Fd
六、in that结构 r[HT9
在表示“原因”概念的引导词中, uMFV%+I
because of +名词, {K7YTLWY
consequently是副词 V,LVB_6
而“in that”是原因状语的引导词。 3q &k
d5U; $q{o
例1:Mercury differs from other industrial metals wRVD_?
---- it is a liquid.
^Omfe
(A) whereas +{rJ[J/g
(B) in that O{n<WQd{CY
(C) because of eoJ]4-WFq
(D) consequently If.n(t[M9
分析:空格前后都是完整的句子,空格处显然缺从句引导词。C、D不能引导从句,可以首先排除。 xv0M
根据题意,两个句子之间是因果关系而不是对比关系,故选(B)。in that为复合连词,用来引导原因状语从句。 6An{3"
V.,bwPb{9
例2:Hovercraft, or air-cushion vehicles, are unusual wD=am
-- travel over land and water on a layer of air. ){tPP$-i=
(A)they
!0dX@V'r
(B)in they @+dHF0aXd
(C)that they pF='jj51
(D)in that they rv?!y8\
分析:空格处缺从句引导词和从句主语。A和B缺从句引导词,首先被排除。C一般作宾语从句或定语从句,而句中需要的是状语从句,故也排除。D中in that为连词,引导表原因的状语从句,符合题意(气垫船之所以不同,是因为……),故选D。 (9z|a,
0P9Wy!f7
*8206[y
这里我们再重申一下,如果选项中出现“介词+which”或者“in that”,那么首先考虑这个选项,如果后面使用的是完整的句子结构,那么这个选项就一定是答案。这种题目平时出现的不多,但是要考的话一定就是重点。 1NGyaI
#PH#2/[
例3:Emily Dickinson's garden was a place ------ NUu;tjt:
great inspiration for her poems. :A*0 ]X;
(A) that she drew ,cS0
(B) by drawing her O#PwRud$
(C) from which she drew R2Yl)2
D
(D) drawn from which "
GLYyC
分析:首先看选项C, “介词+which”, 而后面是she drew great inspiration for her poems.是一个完整句子,那么选项C就是答案。 LJ
l1v
七、what结构 Z~RdFC
what结构在95.8以后的新题中考的非常多,记住一点: e/P4mc)
what=the thing that )rbc;{.
CLktNR(45
例1:The chief foods eaten in any country depend i^/DiWdyf
largely on ----- best in its climate and soil. V7n >,k5
(A) it grows <>&89E%j'
(B) what grows 1)gv%_
(C) does it grow tgfM:kzw
(D) what does it grow HIrE
v
分析:空格前有depend on这个短语,四个选项都是句子,故可判断出空格处为宾语从句。A和C没有从句引导词,故排除,(D)的语序有问题,从句不能用特殊疑问句的倒装形式,故(B)正确。 X,&xhSzg?
{NY]L==H
例2:During the eighteenth century, Little Turtle "&Ff[O*
was chief of the Miami tribe whose territory w@2~`<Hk'"
became----is now Indiana and Ohio. S8vx[ <
(A) there ,?fN#gc :
(B) where FQQ@kP$
.
(C) that +RdI;QmM
(D) what GtG&yeB
分析:空格处缺的词既要引导从句又要作从句主语。四个选项中只有D符合条件。 z6Fun
N]V/83_
B6(h7~0(<
八、同位语结构 G~O" / WM
同位语考试形式一:名词作主语,主语同位语 M,ppCHy/$
___, __ _, ___ (注意是两个逗号) [Yn;
G7cK
例1:The tongue , -----, is an important aid in chewing u1wg
C#

(A) is the chief organ of taste #i@ACAgn;6
(B) tasting the organ chiefly +tPx0>p;
(C) the chief organ of taste dG"K/|
(D) the organ chiefly tastes 9=H}yiJz
分析:空格处显然缺定语或同位语。句中已有谓语动词is, 故先排除A和D。(B)不合题意,故也可排除。(C)是名词短语,适合作主语的同位语,使句子完整,句意正确,故选(C)。 'n>EEQyp'
S_ZLTcq<1
T4Xtuu1
同位语考试形式二:名词作主语,后面的名词是主语同位语,解释说明后面的名词 =rtS#u
Y
___, ___ (注意是一个逗号) / *AJ+K._
例2:A prolific writer of prose and verse, ----of &zO3qt6

(A) Helen Hunt Jackson took up the cause \nrgAC-b
(B) the cause taken up by Helen Hunt Jackson f2`P8$U)R
(C) was Helen Hunt Jackson's cause R|nEd/'<
(D) the cause that Helen Hunt Jackson took up. vYYS.ve
分析:空格前为名词短语,空格后为介词短语,空格处明显缺主语和谓语动词。根据空格前名词短语的意思判断,主语应该是人名而不是指物的名词,故选(A)。

例3:Often very annoying weeds ,-----and act as R5m`;hF
hosts to many insect pests. aJEbAs}
(A) that crowd out less hardy plants than 5{

(B) crowding out less hardy plants by goldenrods _!
CK
(C) the goldenrod's crowding out of less hardy }pbBo2
plants muL>g_H
(D) goldenrods crowd out less hardy plants b`(yu.{Jn
分析:空格后面是and, 句中缺少与and并列的谓语动词。A只有从句没有主句; B,C分别是分词和名词短语, 无法与动词act并列; D 包含主语的同位语goldenrods和谓语动词crowd。 `Ev A\f
Cf.pTYSl
83{x"G3>
同位语考试形式三:主谓宾后面出现一个名词,那么名词可以作宾语或者表语的同位语 dE 3i=
例4:An Olympic marathon is 26 miles and 385 +A]&AkTw
yards, approximately ---- from Marathon to d9`3EP)n

(A) the distance is %E4$ZPSW
(B) that the distance is Ymwx(Pm
(C) is that the distance bs<WH`P
(D) the distance
7yMieUF
分析:逗号前为完整的句子,后面如果再接句子一定要有连接词或者从句引导词。A、B、C均为主谓结构,但都没有从句引导词,故排除。D是名词短语作表语同位语,故选(D)。 o|rGy5
XV74Fl
九、比较结构 1?/5A|?V4+
比较结构中要注意两点:1、倒装性;2、对称性 kGB#2J
例1:Western Nebraska generally receives less b5iIV1g
snow than --eastern Nebraska. ^BF@j4*~
(A) does LV}UBao5n
(B) in LU-#=1Q
(C) it does in u\Nw:Uu i
(D) in it does pl
jV|.?
分析:than引导比较状语从句,空格后面是个专有名词,肯定是比较从句的主语,空格处明显缺从句的谓语动词,只有(A)符合条件,故选(A)。注意than eastern Nebraska does 是正确的语序,但是原文中使用了倒装;在比较结构的后面部分中,如果比较从句的主语长,谓语动词短,动词可放到主语前面进行到装。 *eJhd w*
zxk??0]/
例2: Hot objects emit----- do cold objects. ]>VJ--fH
(A) rays more than infrared USnD7I/b
(B) rays are more infrared than /tI d#/Y
(C) more than infrared rays 7| h3.
(D) more infrared rays than tF#b&za
分析:emit为及物动词,空格处缺宾语和引导比较从句的than, 只有(D)符合条件。注意空格后为倒装形式,do代替emit以避免重复。此题为常考的句子结构。 6T{o3wc;
buq *abON
~xlMHf
比较结构中还需要注意相互比较的必须属于同一种事物 6k@% +<1
例3:The activities of the international marketing 9sfB+]}h
researcher are frequently much broader than ----. [B2>*UPl
(A) the domestic marketer has )|{1&F1
(B) the domestic marketer does *0Wi^f
(C) those of the domestic marketer 0%A(dJA6
(D) that which has the domestic marketer H3/Y
分析:本题还是考查比较句,由于谓语动词是系动词are, 故先排除与其不对应的以has和does结尾的(A)和(B)。选项D则语义不清,也可排除。C中those代替前面提到的activities以避免重复,those一定要具备,因为只有这样才能满足比较的都是activities,谓语动词are因与主句谓语动词相同而被省略,因此C为正确答案。 Y1U"HqNl*
1,%#O;ya
例4:The annual worth of Utah's manufacturing aowPji$H
is greater than --. Pt PGi^
(A) that of its mining and farming combined H/^TXqQ8
(B) mining and farming combination zP{<0o
(C) that mining and farming combined Fl#VKU3h
(D) of its combination mining and farming !5E%W[
分析:本题为比较句,一般来说,比较的双方应属于同一类事物。句中主语显然是比较的一方,而空格处应是与之相对应的另一方。(B)、(C)、(D)均无法与the annual worth相对应,故可以排除。(A)中代词that代替 the annual worth, 是英语中常见的避免重复的用法,故选(A)。 lk
Sz7dr@
#T$'.M
十、定语从句省略结构 -NflaV~
关系代词在定语从句中做宾语时可以省略 >F\rBc&
例1:Most crocodiles will eat anything----capture ok\/5oz
and overpower. '^-4{Y^2E
(A) can bWC~Hv
(B) they can k`2B9,z
(C) which can |S>J<]H
p
(D) and ^7s6J{<
分析:空格前是个完整句子,空格后是两个并列的及物动词,后面却没有宾语,由此可推断出空格处缺能作从句宾语的从句引导词和从句主语。(A)、(D)没有从句引导词,可首先排除。(C)有从句引导词,也可作从句的宾语,却没有从句主语。正确答案(B)看似没有从句引导词,实际上是省略了引导词that,故选(B)。that they can capture, that引导定语从句在句子中做capture的宾语。 BJO~$/R?v
Z:B Y*#B
例2:A majority of people in the United States can =:n[{/O=
get all the calcium their bodies----from the "13
:VTs[5
food they eat. YnO1Lf@
(A) require Ti@P4:q
(B) requires 9tc@
(C) requiring sNk>0 X[
(D)to require HDW\S#
分析:此题显然缺从句谓语动词,故首先排除(C)和(D)。(B)为第三人称单数形式,与主语bodies相矛盾,故也可排除,因此选择A。 Y%?!AmER
their bodies require from the food they eat是定语从句修饰calcium, 省略了that; 实际上they eat也是定语从句省略了that修饰the food qLW-3W;WUH
T`'3Cp$q
,f/IG.
“介词+名词”在定语从句中做表语时,关系代词和be动词可以同时省略,剩下的形容词短语做名词的后置定语。 >g
i{x|/
例3:To produce one pound of honey , a colony of i2ml[;*,N
A A^Hp #b@
bees must fly a distance equals to twice around %wjU^Urya
B C D A$"$`)P!
the world. *}iT6OJ
分析:句子中实际上是省略了that is, a distance that is equal to, 因此equals to 应该改为equal to |C2.Zay
,tR'0&=
例4: A neutron star forms when a star much more massive X"khuyT_
A B C k}0
than the Sun dies and exploded. l-h7ks
Rs
D ,cO)Sxj
分析:句中省略了which is, a star which is much more rgZrE;*;
?L#SnnE
十一、状语从句省略结构 XOU-8;d
Metals expand when they are heated. \7tvNa,C
Metals expand 是主句;when they are heated 是状语从句。但是这个状语从句中可以省略掉they are, 句子变成:Metals expand when heated. 但是并不是所有的状语从句都可以这么省略。这种省略从句主语的方式理论上需要满足以下两个条件: K~ /V
+U/ "F|M
第一、从句主语和主句主语必须保持一致; 5~R{,]52
第二、从句的谓语必须是be动词,主语和be动词同进同出, n_Hnk4
比如上面的they和are要么同时省略,要么同时保留。 .W+4sax:
Umwg
iw
例1:Although----rigid, bones exhibit a degree of oD}FJvV
elasticity that enables the skeleton to withstand jeBj
considerable impact. r`g;k&"a
(A) apparently `M<G8ob
(B) are apparently *U^I`j[u
(C) apparently their .&Gtw
_
(D) are they apparently :3*oAh8|
分析:连词although通常引导主谓完整的状语从句,当从句主语与主句主语相同、从句谓语又为系表结构时,则可省略主语和连系动词,故正确答案为(A)。Although apparently rigid = Although bones are apparently rigid, 注意bones和are必须同时省略。 NGQIoKC
g(r'Y#U
u]-El}*[
因此,我们从上面的例题中来分析一下填空题中状语从句省略以后的形式: 4_:e+ ql
though, although, even thought, while, If, when等为引导状语从句的词; ~4` ec
这些词后面一定+形容词(分词),主句(注意逗号的后面是主句,前面是从句) ;S27m]Q?

例2:All marble is composed of crystals of the iw;Alav"x
minerals calcite or dolomite, ----, are perfectly kRa$jD^?

(A) when, pure which ct/THq
(B) when, which pure "MP{z~Mmj
(C) which, pure when =|zLr"
(D) which, when pure vKLG9ovlY
分析:空格前是个完整的句子,空格后是系表结构,空格处显然缺非限定性定语从句的引导词兼作从句主语。(A)、(B)不引导非限定性定语从句,可首先排除。(C)中的pure和when位置错了,故选(D)。注意when pure是插入语,同时也是省略用法when they are pure;which are perfectly white, 状语从句省略结构, \/%Q P
E8
Ds5&5&af
例3:--relatively costly, the diesel engine F+^[8zK^
is highly efficient and needs servicing '~=xP

(A) Even [beuDZA
(B) It is mM~Q!`Nf.
(C) Even though IN*Z__l8j`
(D) There is &G,v*5N8$K
分析:B和D填入后,都是构成两个主句,不对;Even though则引导状语从句,even though it is, 这里it is 已经省略。 KiHAm|,
`u)V9{
十二、动词ing+名词的复数作主语结构 KA[Su0
这是一个比较难的结构,因为许多同学经常混淆动名词和现在分词。 ]qQB+]WN
现在分词相当于形容词,和后面的名词是修饰与被修饰的关系; 9{&x-ugM
动名词是相当于具有动词特征的名词,和后面的名词是动宾关系。 TQfY%GKg(
@}}1xP4Sr
那么如何在句子中判断动名词和现在分词呢?我们来看两个例子: R|yTUGY
Doing exercises is a good habit. 做练习是一个好习惯。 c9K\K~bk
The starring troops have to surrender. 'a9.JS[pj
第一个句子强调的是做,而不是练习,不能说练习是一个好习惯,只能说做练习是一个好习惯,因此do是中心词,它和后面的名词是动宾关系,那么这个do就是动名词; S+ x[1#r
第二个句子说挨饿的军队必须投降,是军队投降,而不是挨饿要投降,因此中心词是troop,starring是来修饰troop的,因此starring是现在分词。 ";%1sK
{GY$J<5=
在“动词ing+名词的复数”作主语结构的句子中,谓语动词是系动词is +<#-52br\
/;J;,G`?
例1:--by transferring the blame to others is often #]a0 51Y
called scapegoating. .4-S|]/d,
(A) Eliminate problems @ZWKs
(B) The eliminated problems(被消除的问题) =!2
(C) Eliminating problems _TiF}b!hi
(D) Problems are eliminated VzNH%
分析:空格处缺主语。(A)不能作主语,(B)的名词为复数,与后面谓语动词相矛盾,(D)使句子出现两个谓语,故排除。(C)构成动名词短语,可作句中主语,故选(C)。这个题目的意思是通过把责任转嫁给别人,这种消除问题的方式,通常叫做替罪羊。 qz):YHxT]n
/_HL&|N_5
例2:--wooden buildings helps to protect them f+RDvgkKU
from damage due to weather. nfU}ECun4
(A) Painting q9>w3
<
(B) Painted }r[BME
(C) The paint e!yt<[ph
(D) By painting IbC)F> Dq
分析:从谓语动词helps可判断出主语不可能为buildings, 因为主谓语在数上不一致,故空格处缺构成单数的词。四个选项中只有动名词painting符合这一条件,故选(A)。(B)构成复数名词短语,(C)无法与后面的名词连接,(D)构成介词短语,不能作主语,三个选项都可排除。 g>{=R|uO5
painted wooden buildings 被油漆的房子,中心词是buildings, 后面help不能用单数 ME"/%59r
painting wooden buildings油漆房子这件事情,中心词是painting sP#5l @
a'r\e2/e?H
例3:Scientists think -- helps some tree to 1>LquZ+Kj
conserve water in the winter. %\u>%s<9
(A) when losing leaves ]](hwj
(B) leaves are lost )ALcmC?!#
(C) that losing leaves 5Dd;?T>
(D) the leaves losing a7ty&[\
分析:这道题目大家都能够选择C, 但是我们必须彻底理解C为什么正确,think that后面是宾语从句。losing是及物动词,丢弃叶子帮助树来保持水分,要注意不是树叶来帮助保持水分,而是丢弃树叶这个动作来保持水分。丢弃叶子是树主动丢弃,因此losing是动名词。

十三、make结构 GOjri
make结构即为:make +sth.(宾语) +possible+(宾语补足语) d4U_Wu&
共有三种形式: ZzY6M"eUXD
make it possible+to do "lm3o(Dk
make it possible+that引导的从句 Y\\&~g42R2
make possible sth (这个sth一定很长,它后面有一个后置定语) )DW;Gc
kK(,FB
做题技巧: !

如果possible后面有to do 或者that引导的定语从句, 中间一定有it QCMF_;aNI
如果possible后面有名词,中间一定没有it 6 [IiJhVL

分析:此题考动词make的一种用法,visible后面有名词,因此中间不能有it,选择C;可以看到空格后that引导的是定语从句,visible是宾语补足语,宾语补足语的存在是因为宾语太长了,details是宾语。 *ZRQ4i[+

例2:Using many symbols makes--to put a large %*,'&S

(A) possible IP-mo!Y.
(B) it possible V\A?1
(C) it is possible hTF]-&
hZ
(D) that possible \JX8`]|&
分析:从四个选项可以判断出本题考make的一种惯用法。首先排除明显的错误选项:C为句子,却没有与主句相连的连词,D中that后面应有主语并构成结构完整的从句。 由于后面是动词不定式,因此possible前面一定有it, it作形式宾语,故B正确。 h[Hw9$31

十四、the more …the more…结构 1 #_R`(C{
这个结构的意思是“越….越…”,结构一共有三条规则: #P1k5!u
1. the more后面的名词必须使用冠词或者所有格, 新题专门考这条规则 SH"O<cDp
2. the more 后面的谓语如果是be动词的话,可以省略,例如上面的例题 kZeb^Q+,
3. 第二个the more 后面可以使用倒装,而第一个后面却不行 ' y1=Z
the more, the more其实是原因状语从句,前面是原因,后面是结果,倒装句中必须是主句倒装,从句绝对不能够倒装。 )g)X~]*

(A) of 2\_}81hM
(B) the Y2}\~I0
(C) is the ,_HVPE
(D) is of the |GLa`2q|
分析:本题显然考查”the more … the more…”结构,the more后面的名词必须使用冠词或者所有格,因此只能选择B oQAD

十五、表示结果的伴随状语结构 (Rj'd>%c
主谓宾完整的句子后面,如果出现两个词,thereby或者thus, 那么这两个词后面必须使用现在分词,表示“从而怎么样”的意思,这便是表示结果的伴随状语结构。但是必须注意并不是thus后面就是加doing,必须是前面一个完整的句子才对。 P

C a*/%EP3
renditions of romantic love songs in a large hall. @M=xdZNyJ
D R<]f[
分析:Possible后面有名词,那么it应该去掉,thus后面表示结果的伴随状语从句,表示从而使得歌曲演唱成为可能。 .d/e?H:

(A) however tg5G`P5PJ
(B) thus s&.VU|=VQ@
(C) and *UxN~?N|
(D) moreover ,.6)y1!
分析:逗号前面是个完整的句子,逗号后面是现在分词短语作状语表示结果。四个选项中只有thus一词可直接放在现在分词前面,故选B。thus 副词,修饰分词winning, 伴随状语 <gfkbDP2

分析:thereby和to有意思重复,所以不能够选择(A), 后面应该跟现在分词,答案为B xZ84q'i"

十六、形容词最高级省略结构 6v1F.u

最高级后面的名词与范围名词重复,可以省略,句子变为The crane is the tallest of the wading birds. (,P6cWt}"

例1:The crane is--of the wading birds. X<p'&
(A) the tallest 1^v?
Ly8
(B) the tallest that is 9jkaEn>m^
(C) which is the tallest :@oy5zib
(D) which the tallest is + $Yld{i
分析:空格前是主语和谓语,空格后是of引导的介词短语,空格处明显缺作表语的名词或名词短语。四个选项中只有(A)使句子结构完整,语义清楚,故选(A)。 A(2!.Y

例2:. Cows are said to be the least intelligently of 5`tMHgQO

十七、规则动词过去分词作定语结构 Tm) (?y
这里的规则动词指的是过去式和过去分词一样,导致考生看不出句子结构,比如: a}
p}G\b|
program, programmed, programmed
S9 VD/
因此判断这个词是过去式还是过去分词就显得比较重要: ^hy Y,X
第一步:从逻辑上判断这个动作是主动还是被动 K3I|d;Y~X!
第二步:如果是被动的话,做谓语前面一定有系动词be l =`?Im

(A) That the Lbwc2Q,.-
(B) In the <RaUs2Q3.
(C) Around the E(p*B8d
(D) The yd+.hg&J
分析:空格后是结构完整的句子,空格处显然缺定冠词the 修饰主语,故选D。A中that引导主语从句,使整个句子变成从句而无主句,B、C构成介词短语,使句子缺主语,故排除。句子中的built是过去分词。 Bkaupvv9S

(C) made E/5/5'gBJO
(D) are made )Bo]+\2
分析:空格前为名词作主语,空格后是介词by引导的动作执行者,called是过去分词作定语,所以句子缺谓语,故选D。A、B、C均为非谓语动词,故排除。 @;1Ym\zc

例3:Automatons programmed to perform a given H7Y :l0b

(A) without Mq,2S
(B) lack JK=0juv<E
(C) minus o>Faq+@
(D) not having "x~su?KiA
分析:programmed在句中是过去分词作名词后置修饰语,空格处缺谓语动词。四个选择答案中只有(B)是可作谓语的动词,故选(B)。 P g.j]
B, programmed是一个定语,而不是谓语 FzM<0FJRX
机器人被编制程序,所以是过去分词,而不是谓语动词 :SJxG&Pm=~

十八、逻辑主语结构 BH3%dh:9
在一个完整的句子前面出现现在分词、过去分词、或者介词短语,那么这个句子的主语是前面这三种结构逻辑上的主语。 i8Xz'Sw07
6*r#m%|
例1:Having been served lunch, --. fMluVND

(D) a discussion of the problem was make by Wz&[cj

(B) The Dutch settled Brooklyn %n)H(QPW
(C) Brooklyn was settled by the Dutch kK%@cIXS3
(D) Settled by the Dutch, Brooklyn WWgJ !Uz
分析:空格后面是谓语和状语,空格处缺主语。Brooklyn表示人或者Dutch表示地方做主语,但是从as a city可知,主语不是人名,而是地名,由此首先排除A。B、C均是句子,不合要求。D符合句法和题意。 %}[/lIxaE

十九、复合宾语结构 pykRi#[UrX
有些及物动词+宾语后意思表达不完整,需要再加形容词或者名词来补充说明宾语被叫做不完全及物动词,该形容词或者名词叫做宾语补足语。宾语加补足语叫做复合宾语。当宾语和宾补由主动语态变为被动语态,分别变为主语和主补。 Z&5cJk

二十、It结构 ]-g4Ct_V
一、强调句型 Df0m
It is + 强调部分+that +其余部分 PZhpp"
fe7DS)U
这个句型需要注意几点: Uc5BNk7<=
强调部分+其余部分是一个完整的句子; $GX9-^og=T
强调部分可以强调主语、宾语和状语,不能强调谓语和定语; 2IFEl-IB[
强调人使用who或者that, 其他的只能用that (即使是时间和地点),who 和that绝对不能省略 RhI>Ak;-
如果原句是过去时态,强调句型使用it was.,例如: C%;J9(r
原句: Ann bought these books last year. Fes/8*-
强调宾语:It was these books that Ann bought last year. A IsXu"
强调状语:It was last year that Ann bought these books. |v= */e
!T1)tGrH
二、形式主语 ~19&s~
It is + 名词/形容词+ to do/that 引导的句子 @ \JoICz
to do/that 引导的句子是真正的主语,it 是形式主语,这是为了避免头重脚轻。 6"_ytqw7

例1:It is the interaction between people , rather than o7t#yw3
A B j$}W%ibj
the events that occur in their lives , that are c~{)vL0K
C .eG_>2'1
the main focus of social psychology. ^fT?(y_=e
D 'A#F< x
分析:Rather than …是插入语,主句是强调句型, it is …that, 主语是interaction, 所以是is
F!~o J
W5zlU2
例2: --an increasing international exchange of ^HI}bS1+|
educational films. i")ucrf
(A) It is $+p4X# _
(B) There is SZm&2~|J
(C) Though there is O`Ge|4
(D) Although it is U+'h~P'4
分析:缺少主谓,选择B, it 用在句子的句首,只可能作强调句型或者形式主语。空格后是一个名词短语,只有B与之构成完整的句子。A语义不完整,C、D则使整个句子成了让步从句而缺主句,故都可排除。 ~t.M!vk

~91) DNaE
二十一、which 引导的定语从句结构 $(ei<cAV
which是关系代词,which后面应该加缺主语或者宾语的句子, P xiJ R[a
在这个句子中,which要作成分,作主语或者宾语 e BxOa
"I)`gy&
in which+完整的句子 =r1@?x
which在定语从句中作in的宾语,所以不能作后面句子的主语 CiTjRJ-ZW)
]Z#=w
名词+of which+谓语动词 9#ZR0t.cY
of which来修饰名词,名词在定语从句中作主语,所以后面直接跟谓语动词 PcQqdU^!
L>1i~c&V
例1:In blank verse--of ten syllables, five of ?Z[`sm
which are accented. ew{(@p+$
(A) line consists of each j1U,X
(B) consists of each line Qfd4")zhG
(C) each line consists uf<nVdC.
(D) it consists of each line y?*4SLy
分析:空格前后均为介词词组,逗号后为非限定性定语从句,空格处缺主句主谓成分。A单数名词line前没有限定词,而且语义不清,B没有主语,D中it 指代不明,所以选C。 }[m,HA<j
five of which are accented表示其中五个要被重读,of which修饰five, 十个中的五个 U5x&?n<
zs@xw@
例2:The spiral threads of spider's web have a "g>, X[g
sticky substance on them ------ insects. RNB ha&
(A) traps Uc<j{U
,
(B) trap its POtwT">z
(C) which traps 8C(@a[
V
(D) which it traps n~|sMpd,M1
分析:空格前为完整的主谓结构,后面是一个名词,A和B显然不能与前面的谓语动词并列,故可以首先排除。D中的代词it明显是多余的,故也不对。C为正确选项,其中关系代词which指代前面的名词短语a sticky substance。网上有粘状的物质来诱捕昆虫。 U#=5HzE

(A) in which the influence ?\7$63gBH
(B) of which influenced )J<VDO:_YA
(C) to have influence
lI"~
*"c`
(D) its influence in ?wpS
分析:第二个逗号前为结构完整的句子,A中有从句引导词which, 却没有谓语动词,构成不了完整的句子。C中最后一个词为名词,无法与后面的名词短语连接,D构成名词短语,不合题意,而且名词influence一般接介词on, 故三个选项都可排除。B构成一个非限定性定语从句,故选B。
