托福填空題?嫉慕Y(jié)構(gòu)

發(fā)布時間:2010-10-26 文字大小:  打。打印此文

一、主句單一原則
任何一個句子中只可能有一個主句。
做題時考生需要首先判斷原題中已經(jīng)給出的句子結(jié)構(gòu),如果已經(jīng)有一個主句,那么就絕對不能夠再出現(xiàn)另一個主句,除非中間有連接詞進(jìn)行聯(lián)系。

例1:--, work songs often exhibit the song culture of a people in a fundamental form.
   (A) They occur where they are
   (B) Occuring where
   (C) Where they occur
   (D) Where do they occur
分析:空格后面是一個主句,(A)為帶有從句的主句,空格后又是主句,有兩個主句一定錯。
C為地點(diǎn)狀語從句,正確(勞動歌曲發(fā)生的地方)。

例2: --Indiana, is in a rich farming and dairy area, it is primarily a diversified industrial center
   (A) Fort Wayne
   (B) Although Fort Wayne
   (C) For wayne is in
   (D) Fort Wayne, in
分析:空格后有兩個謂語動詞但中間沒有連接詞,由此可知,最后一句話是一個主句,空格處應(yīng)該有從句引導(dǎo)詞,四個選項中只有(B)中although能引導(dǎo)從句,故選(B)。


二、謂語動詞專一原則
任何一個句子只可能存在一個謂語動詞。
句子中不可能沒有謂語動詞,也不能多于一個謂語動詞(除非中間存在連接詞)。

例1:William Walker's mural, “Wall of Respect,”
   -----an outdoor wall in Chicago, deals with
   social issues.
    (A) covers
    (B) covers it
    (C) which covers
    (D) which it covers
分析:空格后的deals with 是謂語動詞,A, B是謂語形式, 和deals with 之間沒有連接詞,可先排除; D 中的it多余,因?yàn)樵诙ㄕZ從句中which已經(jīng)作了主語;C構(gòu)成正確的定語從句


例2:In copper engravings and etchings, -----caused
   by the edges of the plate is clearly visible on
   the paper.
   (A) the impression is
   (B) if the impression is
   (C) impressions
   (D) the impression
分析:題目中的is是謂語,A,B中是謂語重復(fù)。C為復(fù)數(shù)名詞,與后面的謂語動詞is的數(shù)不一致,故也排除。因此選擇D,caused.... 修飾impression
三、平行結(jié)構(gòu)
技巧:如果填空題中空格的后面有and, 或者and后面有空格,那么這道題目一定是考察平行結(jié)構(gòu)。
填空題中平行結(jié)構(gòu)出現(xiàn)的形式是:
A and B,
A , B, and C

例1:The technique of recording, classifying, and--
   is known as accounting.
   (A) an enterprise's transactions summary
   (B) the summarizing of an enterprise's
     transactions
   (C) transactions of an enterprise are
     summarized
   (D) summarizing the transactions of an
     enterprise
分析:空格的后面是and, 一般考平行結(jié)構(gòu),空格處缺與前面recording、classifying并列的動名詞。
   四個選項中只有(D)符合條件,故選(D)。

例2:Louis T. Wright, a surgeon, developed
   ingenious orthopedic braces, --, and
   supervised the first use of Aureomycin on
   human patients.
    (A) treating skull fractures that he pioneered in
    (B) pioneered in treating skull fractures
    (C) which pioneered in treating skull fractures
    (D) he was a pioneer in the treatment of skull
     fractures
分析:空格后面是and, 空格處缺少和developed、supervised平行的謂語動詞,因此選擇(B)。

四、賓語從句結(jié)構(gòu)
賓語從句的引導(dǎo)詞在前面的主從復(fù)合句中已經(jīng)提到。
這里指出的是填空題中關(guān)于賓語從句考的最多的兩個結(jié)構(gòu):
     state(陳述,表明)+that
     indicate(指明,表明)+that

例1:The quantum theory states --, such as light,
   is given off and absorbed in tiny definite
   units called quanta or photons.
    (A) energy that
    (B) that it is energy
    (C) it is energy
    (D) that energy
分析:空格前的謂語動詞states一般接關(guān)系連詞that引導(dǎo)的賓語從句,故首先排除C。空格后已有謂語動詞,空格不應(yīng)再出現(xiàn)謂語動詞,因此D正確。


例2:Studies of the gravity field of the Earth
   indicate--yield when unusual weight is
   placed on them.
   (A) although its crust and mantle
   (B) its crust and mantle to
   (C) that its crust and mantle
   (D) for its crust and mantle to
分析:空格處顯然缺謂語動詞indicate的賓語。(A)和(D)不能作賓語,可首先排除。(B)使句子結(jié)構(gòu)混亂、語義不清,因此選擇(D),構(gòu)成賓語從句。
五、介詞+ which結(jié)構(gòu)
許多同學(xué)在選擇which還是介詞+which上總是不太明白,這里有一個技巧可以告訴大家。
“which”后面一定加一個缺主語或者賓語的句子,
因?yàn)椤皐hich”在這個句子中作了賓語或者主語成分。

“介詞+ which”后面則跟一個完整的句子,
因?yàn)椤苯樵~+which”整個結(jié)構(gòu)在定語從句中作狀語。

例1:In the United States, a primary election is
   a method ---- voters select the nominees
   for public office.
    (A) that
    (B)by which
    (C)is that
    (D)by those
分析:空格前后都是句子,因此缺從句引導(dǎo)詞或連接詞,首先排除C和D。
   A能夠引導(dǎo)從句,但是根據(jù)題意,修飾method是不通的。
   B是介詞+which, 引導(dǎo)定語從句,(大選是一種方法,根據(jù)這個方法,選民怎么….);正確

例2: Croquet is a popular lawn game ------ players
   hit wooden balls through wire arches called
   wickers.
   (A) when
   (B) which
   (C) is when
   (D) in which
分析:空格前后都是完整的句子,空格處缺定語從句引導(dǎo)詞,由此首先排除(A)和(C)。但是到底是選擇B還是D,則看從句,從句是完整的句子,那么一定選擇D, 關(guān)系代詞which 前應(yīng)該有介詞。

六、in that結(jié)構(gòu)
在表示“原因”概念的引導(dǎo)詞中,
  because of +名詞,
  consequently是副詞
  而“in that”是原因狀語的引導(dǎo)詞。

例1:Mercury differs from other industrial metals
   ---- it is a liquid.
   (A) whereas
   (B) in that
   (C) because of
   (D) consequently
分析:空格前后都是完整的句子,空格處顯然缺從句引導(dǎo)詞。C、D不能引導(dǎo)從句,可以首先排除。
根據(jù)題意,兩個句子之間是因果關(guān)系而不是對比關(guān)系,故選(B)。in that為復(fù)合連詞,用來引導(dǎo)原因狀語從句。

例2:Hovercraft, or air-cushion vehicles, are unusual
   -- travel over land and water on a layer of air.
   (A)they
   (B)in they
   (C)that they
   (D)in that they
分析:空格處缺從句引導(dǎo)詞和從句主語。A和B缺從句引導(dǎo)詞,首先被排除。C一般作賓語從句或定語從句,而句中需要的是狀語從句,故也排除。D中in that為連詞,引導(dǎo)表原因的狀語從句,符合題意(氣墊船之所以不同,是因?yàn)椤,故選D。


這里我們再重申一下,如果選項中出現(xiàn)“介詞+which”或者“in that”,那么首先考慮這個選項,如果后面使用的是完整的句子結(jié)構(gòu),那么這個選項就一定是答案。這種題目平時出現(xiàn)的不多,但是要考的話一定就是重點(diǎn)。

例3:Emily Dickinson's garden was a place ------
   great inspiration for her poems.
   (A) that she drew
   (B) by drawing her
   (C) from which she drew
   (D) drawn from which
分析:首先看選項C, “介詞+which”, 而后面是she drew great inspiration for her poems.是一個完整句子,那么選項C就是答案。
七、what結(jié)構(gòu)
what結(jié)構(gòu)在95.8以后的新題中考的非常多,記住一點(diǎn):
  what=the thing that

例1:The chief foods eaten in any country depend
   largely on ----- best in its climate and soil.
   (A) it grows
   (B) what grows
   (C) does it grow
   (D) what does it grow
分析:空格前有depend on這個短語,四個選項都是句子,故可判斷出空格處為賓語從句。A和C沒有從句引導(dǎo)詞,故排除,(D)的語序有問題,從句不能用特殊疑問句的倒裝形式,故(B)正確。

例2:During the eighteenth century, Little Turtle
   was chief of the Miami tribe whose territory
   became----is now Indiana and Ohio.
   (A) there
   (B) where
   (C) that
   (D) what
分析:空格處缺的詞既要引導(dǎo)從句又要作從句主語。四個選項中只有D符合條件。


八、同位語結(jié)構(gòu)
同位語考試形式一:名詞作主語,主語同位語
    ___, __ _, ___ (注意是兩個逗號)
例1:The tongue , -----, is an important aid in chewing
   and swallowing .
   (A) is the chief organ of taste
   (B) tasting the organ chiefly
   (C) the chief organ of taste
   (D) the organ chiefly tastes
分析:空格處顯然缺定語或同位語。句中已有謂語動詞is, 故先排除A和D。(B)不合題意,故也可排除。(C)是名詞短語,適合作主語的同位語,使句子完整,句意正確,故選(C)。


同位語考試形式二:名詞作主語,后面的名詞是主語同位語,解釋說明后面的名詞
    ___, ___ (注意是一個逗號)
例2:A prolific writer of prose and verse, ----of
   Native Americans in her novel, Century of
   Dishonor.
   (A) Helen Hunt Jackson took up the cause
   (B) the cause taken up by Helen Hunt Jackson
   (C) was Helen Hunt Jackson's cause
   (D) the cause that Helen Hunt Jackson took up.
分析:空格前為名詞短語,空格后為介詞短語,空格處明顯缺主語和謂語動詞。根據(jù)空格前名詞短語的意思判斷,主語應(yīng)該是人名而不是指物的名詞,故選(A)。

例3:Often very annoying weeds ,-----and act as
   hosts to many insect pests.
   (A) that crowd out less hardy plants than
     goldenrods
   (B) crowding out less hardy plants by goldenrods
   (C) the goldenrod's crowding out of less hardy
     plants
   (D) goldenrods crowd out less hardy plants
分析:空格后面是and, 句中缺少與and并列的謂語動詞。A只有從句沒有主句; B,C分別是分詞和名詞短語, 無法與動詞act并列; D 包含主語的同位語goldenrods和謂語動詞crowd。


同位語考試形式三:主謂賓后面出現(xiàn)一個名詞,那么名詞可以作賓語或者表語的同位語
例4:An Olympic marathon is 26 miles and 385
   yards, approximately ---- from Marathon to
   Athens.
   (A) the distance is
   (B) that the distance is
   (C) is that the distance
   (D) the distance
分析:逗號前為完整的句子,后面如果再接句子一定要有連接詞或者從句引導(dǎo)詞。A、B、C均為主謂結(jié)構(gòu),但都沒有從句引導(dǎo)詞,故排除。D是名詞短語作表語同位語,故選(D)。

九、比較結(jié)構(gòu)
比較結(jié)構(gòu)中要注意兩點(diǎn):1、倒裝性;2、對稱性
例1:Western Nebraska generally receives less
   snow than --eastern Nebraska.
    (A) does
    (B) in
    (C) it does in
    (D) in it does
分析:than引導(dǎo)比較狀語從句,空格后面是個專有名詞,肯定是比較從句的主語,空格處明顯缺從句的謂語動詞,只有(A)符合條件,故選(A)。注意than eastern Nebraska does 是正確的語序,但是原文中使用了倒裝;在比較結(jié)構(gòu)的后面部分中,如果比較從句的主語長,謂語動詞短,動詞可放到主語前面進(jìn)行到裝。

例2: Hot objects emit----- do cold objects.
    (A) rays more than infrared
    (B) rays are more infrared than
    (C) more than infrared rays
    (D) more infrared rays than
分析:emit為及物動詞,空格處缺賓語和引導(dǎo)比較從句的than, 只有(D)符合條件。注意空格后為倒裝形式,do代替emit以避免重復(fù)。此題為?嫉木渥咏Y(jié)構(gòu)。


比較結(jié)構(gòu)中還需要注意相互比較的必須屬于同一種事物
例3:The activities of the international marketing
   researcher are frequently much broader than ----.
   (A) the domestic marketer has
   (B) the domestic marketer does
   (C) those of the domestic marketer
   (D) that which has the domestic marketer
分析:本題還是考查比較句,由于謂語動詞是系動詞are, 故先排除與其不對應(yīng)的以has和does結(jié)尾的(A)和(B)。選項D則語義不清,也可排除。C中those代替前面提到的activities以避免重復(fù),those一定要具備,因?yàn)橹挥羞@樣才能滿足比較的都是activities,謂語動詞are因與主句謂語動詞相同而被省略,因此C為正確答案。

例4:The annual worth of Utah's manufacturing
   is greater than --.
   (A) that of its mining and farming combined
   (B) mining and farming combination
   (C) that mining and farming combined
   (D) of its combination mining and farming
分析:本題為比較句,一般來說,比較的雙方應(yīng)屬于同一類事物。句中主語顯然是比較的一方,而空格處應(yīng)是與之相對應(yīng)的另一方。(B)、(C)、(D)均無法與the annual worth相對應(yīng),故可以排除。(A)中代詞that代替 the annual worth, 是英語中常見的避免重復(fù)的用法,故選(A)。

十、定語從句省略結(jié)構(gòu)
關(guān)系代詞在定語從句中做賓語時可以省略
例1:Most crocodiles will eat anything----capture
   and overpower.
   (A) can  
   (B) they can
   (C) which can
   (D) and
分析:空格前是個完整句子,空格后是兩個并列的及物動詞,后面卻沒有賓語,由此可推斷出空格處缺能作從句賓語的從句引導(dǎo)詞和從句主語。(A)、(D)沒有從句引導(dǎo)詞,可首先排除。(C)有從句引導(dǎo)詞,也可作從句的賓語,卻沒有從句主語。正確答案(B)看似沒有從句引導(dǎo)詞,實(shí)際上是省略了引導(dǎo)詞that,故選(B)。that they can capture, that引導(dǎo)定語從句在句子中做capture的賓語。

例2:A majority of people in the United States can
   get all the calcium their bodies----from the
   food they eat.
    (A) require
    (B) requires
    (C) requiring
    (D)to require
分析:此題顯然缺從句謂語動詞,故首先排除(C)和(D)。(B)為第三人稱單數(shù)形式,與主語bodies相矛盾,故也可排除,因此選擇A。
   their bodies require from the food they eat是定語從句修飾calcium, 省略了that; 實(shí)際上they eat也是定語從句省略了that修飾the food


“介詞+名詞”在定語從句中做表語時,關(guān)系代詞和be動詞可以同時省略,剩下的形容詞短語做名詞的后置定語。
例3:To produce one pound of honey , a colony of
    A
   bees must fly a distance equals to twice around
   B          C      D
   the world.
分析:句子中實(shí)際上是省略了that is, a distance that is equal to, 因此equals to 應(yīng)該改為equal to

例4: A neutron star forms when a star much more massive
          A  B      C
    than the Sun dies and exploded.
              D
分析:句中省略了which is, a star which is much more

十一、狀語從句省略結(jié)構(gòu)
Metals expand when they are heated.
Metals expand 是主句;when they are heated 是狀語從句。但是這個狀語從句中可以省略掉they are, 句子變成:Metals expand when heated. 但是并不是所有的狀語從句都可以這么省略。這種省略從句主語的方式理論上需要滿足以下兩個條件:

    第一、從句主語和主句主語必須保持一致;
    第二、從句的謂語必須是be動詞,主語和be動詞同進(jìn)同出,
       比如上面的they和are要么同時省略,要么同時保留。

例1:Although----rigid, bones exhibit a degree of
   elasticity that enables the skeleton to withstand
   considerable impact.
   (A) apparently
   (B) are apparently
   (C) apparently their
   (D) are they apparently
分析:連詞although通常引導(dǎo)主謂完整的狀語從句,當(dāng)從句主語與主句主語相同、從句謂語又為系表結(jié)構(gòu)時,則可省略主語和連系動詞,故正確答案為(A)。Although apparently rigid = Although bones are apparently rigid, 注意bones和are必須同時省略。


因此,我們從上面的例題中來分析一下填空題中狀語從句省略以后的形式:
  though, although, even thought, while, If, when等為引導(dǎo)狀語從句的詞;
  這些詞后面一定+形容詞(分詞),主句(注意逗號的后面是主句,前面是從句)

例2:All marble is composed of crystals of the
   minerals calcite or dolomite, ----, are perfectly
   white.
   (A) when, pure which
   (B) when, which pure
   (C) which, pure when
   (D) which, when pure
分析:空格前是個完整的句子,空格后是系表結(jié)構(gòu),空格處顯然缺非限定性定語從句的引導(dǎo)詞兼作從句主語。(A)、(B)不引導(dǎo)非限定性定語從句,可首先排除。(C)中的pure和when位置錯了,故選(D)。注意when pure是插入語,同時也是省略用法when they are pure;which are perfectly white, 狀語從句省略結(jié)構(gòu),

例3:--relatively costly, the diesel engine
   is highly efficient and needs servicing
   infrequently
   (A) Even
   (B) It is
   (C) Even though
   (D) There is
分析:B和D填入后,都是構(gòu)成兩個主句,不對;Even though則引導(dǎo)狀語從句,even though it is, 這里it is 已經(jīng)省略。

十二、動詞ing+名詞的復(fù)數(shù)作主語結(jié)構(gòu)
這是一個比較難的結(jié)構(gòu),因?yàn)樵S多同學(xué)經(jīng);煜齽用~和現(xiàn)在分詞。
  現(xiàn)在分詞相當(dāng)于形容詞,和后面的名詞是修飾與被修飾的關(guān)系;
  動名詞是相當(dāng)于具有動詞特征的名詞,和后面的名詞是動賓關(guān)系。

那么如何在句子中判斷動名詞和現(xiàn)在分詞呢?我們來看兩個例子:
  Doing exercises is a good habit. 做練習(xí)是一個好習(xí)慣。
  The starring troops have to surrender.
  第一個句子強(qiáng)調(diào)的是做,而不是練習(xí),不能說練習(xí)是一個好習(xí)慣,只能說做練習(xí)是一個好習(xí)慣,因此do是中心詞,它和后面的名詞是動賓關(guān)系,那么這個do就是動名詞;
  第二個句子說挨餓的軍隊必須投降,是軍隊投降,而不是挨餓要投降,因此中心詞是troop,starring是來修飾troop的,因此starring是現(xiàn)在分詞。

在“動詞ing+名詞的復(fù)數(shù)”作主語結(jié)構(gòu)的句子中,謂語動詞是系動詞is

例1:--by transferring the blame to others is often
   called scapegoating.
   (A) Eliminate problems
   (B) The eliminated problems(被消除的問題)
   (C) Eliminating problems
   (D) Problems are eliminated
分析:空格處缺主語。(A)不能作主語,(B)的名詞為復(fù)數(shù),與后面謂語動詞相矛盾,(D)使句子出現(xiàn)兩個謂語,故排除。(C)構(gòu)成動名詞短語,可作句中主語,故選(C)。這個題目的意思是通過把責(zé)任轉(zhuǎn)嫁給別人,這種消除問題的方式,通常叫做替罪羊。

例2:--wooden buildings helps to protect them
   from damage due to weather.
    (A) Painting
    (B) Painted
    (C) The paint
    (D) By painting
分析:從謂語動詞helps可判斷出主語不可能為buildings, 因?yàn)橹髦^語在數(shù)上不一致,故空格處缺構(gòu)成單數(shù)的詞。四個選項中只有動名詞painting符合這一條件,故選(A)。(B)構(gòu)成復(fù)數(shù)名詞短語,(C)無法與后面的名詞連接,(D)構(gòu)成介詞短語,不能作主語,三個選項都可排除。
painted wooden buildings 被油漆的房子,中心詞是buildings, 后面help不能用單數(shù)
painting wooden buildings油漆房子這件事情,中心詞是painting

例3:Scientists think -- helps some tree to
   conserve water in the winter.
   (A) when losing leaves
   (B) leaves are lost
   (C) that losing leaves
   (D) the leaves losing
分析:這道題目大家都能夠選擇C, 但是我們必須徹底理解C為什么正確,think that后面是賓語從句。losing是及物動詞,丟棄葉子幫助樹來保持水分,要注意不是樹葉來幫助保持水分,而是丟棄樹葉這個動作來保持水分。丟棄葉子是樹主動丟棄,因此losing是動名詞。

十三、make結(jié)構(gòu)
make結(jié)構(gòu)即為:make +sth.(賓語) +possible+(賓語補(bǔ)足語)
共有三種形式:
   make it possible+to do
   make it possible+that引導(dǎo)的從句
   make possible sth (這個sth一定很長,它后面有一個后置定語)

做題技巧:
   如果possible后面有to do 或者that引導(dǎo)的定語從句, 中間一定有it
   如果possible后面有名詞,中間一定沒有it

例1:X-rays are able to pass through objects and
   thus make--details that are otherwise
   impossible to observe .
   (A) it visible
   (B) visibly
   (C) visible
   (D) they are visible
分析:此題考動詞make的一種用法,visible后面有名詞,因此中間不能有it,選擇C;可以看到空格后that引導(dǎo)的是定語從句,visible是賓語補(bǔ)足語,賓語補(bǔ)足語的存在是因?yàn)橘e語太長了,details是賓語。


例2:Using many symbols makes--to put a large
   amount of information on a single map.
   (A) possible
   (B) it possible
   (C) it is possible
   (D) that possible
分析:從四個選項可以判斷出本題考make的一種慣用法。首先排除明顯的錯誤選項:C為句子,卻沒有與主句相連的連詞,D中that后面應(yīng)有主語并構(gòu)成結(jié)構(gòu)完整的從句。 由于后面是動詞不定式,因此possible前面一定有it, it作形式賓語,故B正確。


十四、the more …the more…結(jié)構(gòu)
這個結(jié)構(gòu)的意思是“越….越…”,結(jié)構(gòu)一共有三條規(guī)則:
  1. the more后面的名詞必須使用冠詞或者所有格, 新題專門考這條規(guī)則
  2. the more 后面的謂語如果是be動詞的話,可以省略,例如上面的例題
  3. 第二個the more 后面可以使用倒裝,而第一個后面卻不行
the more, the more其實(shí)是原因狀語從句,前面是原因,后面是結(jié)果,倒裝句中必須是主句倒裝,從句絕對不能夠倒裝。

例1:The stronger--magnet, the greater the
   number of lines of magnetic force.
   (A) of
   (B) the
   (C) is the
   (D) is of the
分析:本題顯然考查”the more … the more…”結(jié)構(gòu),the more后面的名詞必須使用冠詞或者所有格,因此只能選擇B

例2:The less the surface of the ground yields to the
   weight of the body of a runner, --to the body. 
   (A) the stress it is greater
   (B) greater is the stress
   (C) greater stress is
   (D) the greater the stress
分析:正確答案為D。此題考the more … the more句型,只有D符合這一句型的要求,故選D。

十五、表示結(jié)果的伴隨狀語結(jié)構(gòu)
主謂賓完整的句子后面,如果出現(xiàn)兩個詞,thereby或者thus, 那么這兩個詞后面必須使用現(xiàn)在分詞,表示“從而怎么樣”的意思,這便是表示結(jié)果的伴隨狀語結(jié)構(gòu)。但是必須注意并不是thus后面就是加doing,必須是前面一個完整的句子才對。


例1:A microphone enables a soft tone to beamplified ,
             A     B
   thus making it possible the gentle
       C           
   renditions of romantic love songs in a large hall.
         D
分析:Possible后面有名詞,那么it應(yīng)該去掉,thus后面表示結(jié)果的伴隨狀語從句,表示從而使得歌曲演唱成為可能。


例2:The Smithsonian Institution preserves more
   than sixty-five million items of scientific,
   historical, or artistic interest, --winning the
   popular title, “attic of the nation.”
    (A) however
    (B) thus
    (C) and
    (D) moreover
分析:逗號前面是個完整的句子,逗號后面是現(xiàn)在分詞短語作狀語表示結(jié)果。四個選項中只有thus一詞可直接放在現(xiàn)在分詞前面,故選B。thus 副詞,修飾分詞winning, 伴隨狀語

例3: Snow aids farmers by keeping heat in the
   lower ground levels, thereby--from freezing.
    (A) to save the seeds
    (B) saving the seeds
    (C)which saves the seeds
    (D) the seeds saved
分析:thereby和to有意思重復(fù),所以不能夠選擇(A), 后面應(yīng)該跟現(xiàn)在分詞,答案為B


十六、形容詞最高級省略結(jié)構(gòu)
The crane is the tallest bird of the wading birds.
最高級后面的名詞與范圍名詞重復(fù),可以省略,句子變?yōu)門he crane is the tallest of the wading birds.

例1:The crane is--of the wading birds.
   (A) the tallest
   (B) the tallest that is
   (C) which is the tallest
   (D) which the tallest is
分析:空格前是主語和謂語,空格后是of引導(dǎo)的介詞短語,空格處明顯缺作表語的名詞或名詞短語。四個選項中只有(A)使句子結(jié)構(gòu)完整,語義清楚,故選(A)。


例2:. Cows are said to be the least intelligently of
       A  B       C
   domestic animals.
    D
分析:改為形容詞,intelligent,intelligently為副詞,不能作表語。

十七、規(guī)則動詞過去分詞作定語結(jié)構(gòu)
這里的規(guī)則動詞指的是過去式和過去分詞一樣,導(dǎo)致考生看不出句子結(jié)構(gòu),比如:
  program, programmed, programmed
因此判斷這個詞是過去式還是過去分詞就顯得比較重要:
  第一步:從邏輯上判斷這個動作是主動還是被動
  第二步:如果是被動的話,做謂語前面一定有系動詞be


例1:--Wupatki National Monument in Arizona
   features structures built of red sandstone by
   ancestors of the Hopi people.
   (A) That the
   (B) In the
   (C) Around the
   (D) The
分析:空格后是結(jié)構(gòu)完整的句子,空格處顯然缺定冠詞the 修飾主語,故選D。A中that引導(dǎo)主語從句,使整個句子變成從句而無主句,B、C構(gòu)成介詞短語,使句子缺主語,故排除。句子中的built是過去分詞。

例2:Antibodies --by small, round cells called
   lymphocytes and plasma cells.
   (A) to be made
   (B) making
   (C) made
   (D) are made
分析:空格前為名詞作主語,空格后是介詞by引導(dǎo)的動作執(zhí)行者,called是過去分詞作定語,所以句子缺謂語,故選D。A、B、C均為非謂語動詞,故排除。

例3:Automatons programmed to perform a given
   task ------the flexibility and adaptability of
   human beings.
   (A) without
   (B) lack
   (C) minus
   (D) not having
分析:programmed在句中是過去分詞作名詞后置修飾語,空格處缺謂語動詞。四個選擇答案中只有(B)是可作謂語的動詞,故選(B)。
B, programmed是一個定語,而不是謂語
機(jī)器人被編制程序,所以是過去分詞,而不是謂語動詞


十八、邏輯主語結(jié)構(gòu)
在一個完整的句子前面出現(xiàn)現(xiàn)在分詞、過去分詞、或者介詞短語,那么這個句子的主語是前面這三種結(jié)構(gòu)邏輯上的主語。

例1:Having been served lunch, --.
   (A) the problem was discussed by the members
    of the committee
   (B) the committee members discussed the
    problem
   (C) it was discussed by the committee
    members the problem
   (D) a discussion of the problem was make by
    the members of the committee
分析:Having been served lunch指被招待了午飯,那么只可能是委員會的成員被招待,而不可能是問題,所以選擇B

例2:--was not incorporated as a city until
   almost two centuries later, in 1834.
   (A) Settling Brooklyn, the Dutch
   (B) The Dutch settled Brooklyn
   (C) Brooklyn was settled by the Dutch
   (D) Settled by the Dutch, Brooklyn
分析:空格后面是謂語和狀語,空格處缺主語。Brooklyn表示人或者Dutch表示地方做主語,但是從as a city可知,主語不是人名,而是地名,由此首先排除A。B、C均是句子,不合要求。D符合句法和題意。

例3:At thirteen --- at a district school near her
   home, and when she was fifteen , she saw her
   first article in print.
   (A) the first teaching position that Mary Jane
    Hawes had
   (B) the teaching position was Mary Jane
    Hawe's first
   (C) when Mary Jane Hawes had her first
    teaching position
   (D) Mary Jane Hawes had her first teaching
    position
分析:從并列連詞and 可知,第一個逗號前是一個完整的句子,空格處缺主謂結(jié)構(gòu),而且主語是一個人名。四個選項中只有D以人名作主語,故選D。

例4: Even at low levels, --.
   (A) the nervous system has produced
     detrimental effects by lead
   (B) lead's detrimental effects are producing the
    nervous system
   (C) lead produces detrimental effects on the
    nervous system
   (D) the detrimental effects produced by lead on
    the nervous system
分析:空格前為介詞短語狀語,空格處缺一個完整的句子。A、B結(jié)構(gòu)上似乎完整,但意思不清,D不是完整的句子,故選C。

例5:The chorus plays a large part in any oratorio, linking
            A   B     C
   areas were sung by soloists with segments of choral music.
       D
分析:應(yīng)該把D中的were去掉


十九、復(fù)合賓語結(jié)構(gòu)
有些及物動詞+賓語后意思表達(dá)不完整,需要再加形容詞或者名詞來補(bǔ)充說明賓語被叫做不完全及物動詞,該形容詞或者名詞叫做賓語補(bǔ)足語。賓語加補(bǔ)足語叫做復(fù)合賓語。當(dāng)賓語和賓補(bǔ)由主動語態(tài)變?yōu)楸粍诱Z態(tài),分別變?yōu)橹髡Z和主補(bǔ)。
We played soccer.
We called him Bob. Bob在這里作賓語補(bǔ)足語
He was called Bob. Bob在這里作主語補(bǔ)足語

下面列出了一些經(jīng)常要求使用賓補(bǔ)的動詞
make, consider, call, elect, appoint,
例:We appoint him monitor.
  We elected him president.

例1:Poodles were once used as retrievers in duck
   hunting , but the American Kennel Club does not
   consider them --because they are now primarily
   kept as pets.
   (A) where sporting dogs
   (B) sporting dogs
   (C) when sporting dogs
   (D) they are sportingdogs
分析:選擇B, them是賓語,sporting dogs賓補(bǔ)

二十、It結(jié)構(gòu)
一、強(qiáng)調(diào)句型
   It is + 強(qiáng)調(diào)部分+that +其余部分

這個句型需要注意幾點(diǎn):
強(qiáng)調(diào)部分+其余部分是一個完整的句子;
強(qiáng)調(diào)部分可以強(qiáng)調(diào)主語、賓語和狀語,不能強(qiáng)調(diào)謂語和定語;
強(qiáng)調(diào)人使用who或者that, 其他的只能用that (即使是時間和地點(diǎn)),who 和that絕對不能省略
如果原句是過去時態(tài),強(qiáng)調(diào)句型使用it was.,例如:
  原句:  Ann bought these books last year.
    強(qiáng)調(diào)賓語:It was these books that Ann bought last year.
    強(qiáng)調(diào)狀語:It was last year that Ann bought these books.

二、形式主語
It is + 名詞/形容詞+ to do/that 引導(dǎo)的句子
to do/that 引導(dǎo)的句子是真正的主語,it 是形式主語,這是為了避免頭重腳輕。


例1:It is the interaction between people , rather than
    A               B
   the events that occur in their lives , that are
                  C
   the main focus of social psychology.
           D
分析:Rather than …是插入語,主句是強(qiáng)調(diào)句型, it is …that, 主語是interaction, 所以是is

例2: --an increasing international exchange of
   educational films.
   (A) It is 
   (B) There is 
   (C) Though there is
   (D) Although it is
分析:缺少主謂,選擇B, it 用在句子的句首,只可能作強(qiáng)調(diào)句型或者形式主語?崭窈笫且粋名詞短語,只有B與之構(gòu)成完整的句子。A語義不完整,C、D則使整個句子成了讓步從句而缺主句,故都可排除。


二十一、which 引導(dǎo)的定語從句結(jié)構(gòu)
which是關(guān)系代詞,which后面應(yīng)該加缺主語或者賓語的句子,
在這個句子中,which要作成分,作主語或者賓語

in which+完整的句子
which在定語從句中作in的賓語,所以不能作后面句子的主語

名詞+of which+謂語動詞
of which來修飾名詞,名詞在定語從句中作主語,所以后面直接跟謂語動詞

例1:In blank verse--of ten syllables, five of
   which are accented.
   (A) line consists of each
   (B) consists of each line
   (C) each line consists
   (D) it consists of each line
分析:空格前后均為介詞詞組,逗號后為非限定性定語從句,空格處缺主句主謂成分。A單數(shù)名詞line前沒有限定詞,而且語義不清,B沒有主語,D中it 指代不明,所以選C。
   five of which are accented表示其中五個要被重讀,of which修飾five, 十個中的五個

例2:The spiral threads of spider's web have a
   sticky substance on them ------ insects.
   (A) traps  
   (B) trap its 
   (C) which traps
   (D) which it traps
分析:空格前為完整的主謂結(jié)構(gòu),后面是一個名詞,A和B顯然不能與前面的謂語動詞并列,故可以首先排除。D中的代詞it明顯是多余的,故也不對。C為正確選項,其中關(guān)系代詞which指代前面的名詞短語a sticky substance。網(wǎng)上有粘狀的物質(zhì)來誘捕昆蟲。

例3:Traditionally, ethnographers and linguists
  have paid little attention to cultural
   A            
  interpretations given to silence, or to the types of
         B      C
  social contexts in which tends to occur.
           D
分析:D錯,in which后面跟完整句子。In which it, it 指代silence, or to 和第二行的to并列

例4:After the First World War, the author Anais Nin
   became interested in the art movement
   known as Surrealism and in psychoanalysis,
   both --her novels and short stories.
   (A) in which the influence
   (B) of which influenced
   (C) to have influence
   (D) its influence in
分析:第二個逗號前為結(jié)構(gòu)完整的句子,A中有從句引導(dǎo)詞which, 卻沒有謂語動詞,構(gòu)成不了完整的句子。C中最后一個詞為名詞,無法與后面的名詞短語連接,D構(gòu)成名詞短語,不合題意,而且名詞influence一般接介詞on, 故三個選項都可排除。B構(gòu)成一個非限定性定語從句,故選B。
