爱华网1.While playing inthe park one morning，a loud argument was gotten into by several of thechildren over theuse of swings.
(A)a loud argument was gotten into by several of thechildren
(B)a loud argumentbetween several of the children was gotten into
(C)and a loudargument gotten into by several of the children
(D)several of the children getting into a loudargument
(E)several of thechildren got into a loud argument
答案：E
类型：逻辑主语。
解析：句子是doing形式的状语+主句的结构。在语法中，前置doing做非谓语时，doing动作的逻辑主语必须是句子主语，play这个动作的发出者应该是人，所以句子主语只能是人。由此排除ABC三个选项。D选项中，gettinginto不能做谓语动词，属于句子成分缺失。
2. Vitamin D，which the body needs in order to absorbcalcium，is produced when skin is exposed to ultraviolet rays.
(A) calcium，is produced
(B)calcium，and is produced
(C)calcium，producing it
(D) calcium and produces
(E)calcium and produces it
答案：A
类型：句子结构。
解析：句子的主语是维他命D，which引导定语从句做主语的同位语，那么之后必然有句子的谓语动词。因此A选项是正确的。B中and使用错误，and并列成分并不是两个动词。C选项导致主句无谓语动词。DE选项and并列的是定语从句的谓语动词，那么主语维他命D就没有谓语动词了，因此也是错误的。
3. Designing a computer monitor requires not only anunderstanding of electromagnetism，chemistry，and the psychology of human vision.
(A) not only anunderstanding of
(B)both an understanding of
(C)an understanding of not only
(D) an understanding ofboth
(E)an understanding of
答案：E
类型：平行结构
解析：题目中平行的结构是electromagnetism，chemistry和the psychology of humanvision。AC选项可以直接排除，因为onlyonly和and不能连用。题目是三个名词的并列，因此both…and…这个短语也使用不恰当。BD也可以排除。
4. Edgar Allan Poe’s poem “TheRaven,” partlyinspired by a talking raven in the novel Barnaby Rudge by CharlesDickens.
(A)Edgar Allan Poe’s poem“The Raven,”
(B)Edgar AllanPoe，whose poem“The Raven” was
(C)A poem by EdgarAllan Poe， “TheRaven”，whichwas
(D)“TheRaven”by Edgar AllanPoe’s poem，being a poem
(E)“TheRaven”，a poemby by Edgar AllanPoe，was
答案：E
类型：被动语态
解析：注意看到句中inspiredby，这明显是被动语态的表达形式，那么inspired前面缺少一个be动词，因此AD可以直接排除。B选项，whose引导定语从句，导致主语EAP这个人没有谓语动词，因此B错。C选项which引导定语从句，但是主语依然没有谓语动词，因此C选项也错。E选项中，主语是“The Raven” ，两个逗号之间是插入语，wasinspired做谓语动词。E正确。
5. Unlike coniferous trees，whose leaves are usuallyneedlelike，the leavesof deciduous trees are typically broad andflat.
(A)the leaves of deciduous trees are typically broad andflat
(B)it is typical forthe leaves of deciduous trees to be broad and flat
(C)broad and flatleaves are typical of deciduous trees
(D)deciduous trees have leaves that are typically broad andflat
(E)on deciduoustrees，the leaves aretypically broad and flat
答案：D
类型：比较内容平行
解析：unlike后面是coniferoustrees，那么句子主语必须也是tree才能保持平行，符合这一要求的只有D选项。
6. Even choosing the least expensiverate，the package was soheavy that it cost Jose nearly a hundred dollars to mail it to hiscousin in Madrid.
(A) Even choosing
(B)Even though choosing
(C)Even though he chose
(D) Although he hadchose
(E)Although choosing
答案：C
类型：逻辑主语。
解析：choosing的逻辑主语是句子的主语，其动作发出者应该是人，但是句子的主语是thepackage，因此必须要再choose前加上动作发出者，ABE可以直接排除。D选项中，chose使用错误，因为choose的过去分词应该是chosen，综上只能选C。
7. An early American film star，Pearl White starred in several serials whoseepisodes had suspenseful endings that enticed audiences toreturn for the next installment.
(A)serials whose episodes had suspenseful endings
(B)serials，theirepisodes had suspenseful endings
(C)serials，whichhad episodes ending suspenseful
(D)serials of whose episodes the suspensefulendings
(E)serials，each ofthese episodes had a suspenseful ending
答案：A
类型：定语从句
解析：serials之后的内容是来修饰serials的。A选项whose引导定语从句，划线部分之后的that指代的是endings。B选项是典型的run-on句子，两个完整的句子之间没有连词，也不构成主从复合句，B错。C选项错在endingsuspenseful，end在这里是动词，那么suspenseful应该使用副词形式。D选项是定语从句使用错误，whose引导的定语从句不用再加of了。E也是run-on句子。
8. Although we typically associate deserts withhot，drywether，deserts can alsobe cold，most of Antarctica is a desert despite the continent'sfrigid temperatures.
(A)cold，most ofAntarctica is
(B)cold；most ofAntarctica is
(C)cold，infact，most of Antarcticais
(D)cold；whereasmost of Antarctica is
(E)cold，such asmost of Antarctica being
答案：B
类型：句子结构
解析：原句是典型的run-on，两个完整句子之间没有连词，也不构成主从复合句。C与A选项错误类型一样，都是run-on。D选项首先用了分号，分号之后应该是完整的句子，whereas是连词，所以后面部分不是完整句子。E中being不简洁。
9. One reason fish spoilsfaster than meat is due to the fact that the muscle fibersof fish are specialized to function best in cold environments.
(A)meat is due to the fact that
(B)meat is becauseof the fact that
(C)meat，which is because
(D) meat is that
(E)meat，since
答案：D
类型：固定搭配
解析：is due to和is becauseof是SAT语法中不正规的表达。AB直接排除。C选项which引导定语从句，主句没有谓语动词，C错。E选项中since引导状语从句，主语依然不完整。综上，选D。
10. The Canada lynx has oversized，webbed paws thatact as snowshoes，allowing them to hunt rabbits even when thesnow is deep.
(A)allowing them to hunt rabbits even
(B)allowing it tohunt rabbits even
(C)even allowingthem to hunt rabbits
(D)which allow them to hunt rabbits even
(E)this allows it tohunt rabbits even
答案：B
类型：代词
解析：allow的宾语应该是The Canada lynx（三人称单数），所以them直接排除，ACD错误。E选项用this单独使用做主语是错误的。只能选B。
11. The article praised IsakDinesen not so much for her genius as a storyteller but becauseshe was remarkably defiant of society’s expectations of womenduring the early twentieth century.
(A)but because she was remarkably defiant
(B)but because ofher remarkable defiance
(C)but for being remarkably defiant
(D) as for her remarkabledefiance
(E)as it did herremarkable defiance
答案：D
类型：比较和平行结构
解析：首先，句中有一个not somuch…as…的固定搭配表示比较，由此可以直接排除ABC。比较中又有一个平行结构：not for…，butfor…。因此答案选D。
12. While candidates for political office thinkcarefully(A) about the way they dress for publicappearances，butthey(B) generally donot want to appear(C) to care too much(D) aboutclothes. No error(E)
答案：B
类型：句子结构
解析：while和but在句中都做连词，这样导致句子没有主句了。
修改建议：把but删掉。
13. The professor urged(A) her students tofollow(B) their own career interests，to serve their communities，and believing(C) in the power oftheir(D) own ideas. No error(E)
答案：C
类型：平行结构

修改建议：把believing改为to believe。

17. When the finalists in(A) the essay contestreceive their(B) scholarships at(C) the awardsceremony，the first-placewinner was also given(D) a computer. Noerror(E)
答案：D
类型：时态

修改建议：把was also改为will alsobe。
18. Both Serena，who hasjust been(A) elected president of the union，and(B)Martin，its treasurer，attends(C) the weeklymeetings(D) of the labor council. No error(E)
答案：C
类型：主谓一致
解析：句子的主语是both...and...，因此谓语动词不能用三人称单数。
修改建议：把attends改为attend。

答案：A
类型：句子结构

修改建议：把that删掉。

Questions 30-35 refer to the following passage.
(1)When Pluto was first detected in 1930，it was welcomed as a newly discovered planet.(2)Their reaction was understandable. (3)Pluto was initiallythought to be about the size of Earth and therefore of properplanetary dimensions. (4)But by the late 1970s，closer observation had established thatPluto was in fact less than half the size of Mercury.(5)Dismayed，someastronomers now began to question whether so small an objectdeserved to be ranked among the planets.
(6)Pluto differs from the other planets also in that it is composedlargely of ice——more like a cometthan a typical planet. (7)In the 1990s it was discovered that Plutowas just the largest of hundreds of comet-like bodies occupying aregion known as the Kuiper Belt. (8)Pluto，the doubters argued，should therefore be classed with these icy objectsrather than with the planets.
(9)Rushing to Pluto’sdefense，many astronomersrejected these arguments，pointing out that the established planets differ amongthemselves in both composition and size.(10)Mars，forinstance，is composed ofmetal and rock，whileNeptune is mostly gas. (11)Why，then，could aplanet not just as well be composed of ice？ (12)And as for sizedifference，Jupiter is1300 times larger than Earth，but no one would suggest that the two bodies thereforecannot both be planets.
(13)Clearly they need to resolve the issue ofPluto’s classification. (14)In 2006 theInternational Astronomical Union defined a planet as a body thatdirectly orbits the Sun，is large enough to be rounded by its owngravity，and has clearedits neighboring region of other orbiting bodies. (15)Pluto wasjudged to satisfy the first two criteria but not thethird，because of all theKuiper Belt objects populating its neighborhood.
30. In context，which of the following is the best version of theunderlined portion of sentence 1（reproduced below）？
When Pluto was first detected in1930，itwas welcomed as a newly discovered planet.
(A) (as it is now)
(B)it was a newlydiscovered planet and welcomed as such
(C)being a newlydiscovered planet，it waswelcomed
(D)the newly discovered planet was also welcomed byastronomers
(E)astronomerswelcomed it as a newly discovered planet
答案：E
解析：Sentence 2的their指“一群人”，故Sentence1要出现“一群人”，只有E选项是astronomers正确。ABC直接排除; D被动句，不简洁，且意思有所改变。
31. In context，which of the following revisions of the underlined portionof sentence 4(reproduced below)would add the most relevantinformation？
But by the late1970s，closer observation had established that Pluto was in factless than half the size of Mercury.
(A)Mercury，theplanet closest to the Sun
(B)Mercury，thesmallest of the traditional planets
(C)Mercury，whichwas named for a Roman messenger god
(D)Mercury，whichwas discovered in ancient times
(E)Mercury，whoseatmosphere is too thin to support human life
答案：B
解析：Sentence 5：一些天文学家质疑Pluto太小，认为它不能算作行星。Sentence 4：Pluto比Mercury的一半还小，此处添加的内容必须要凸显Pluto太小，与其他的planets的大小相差过大，从而与Sentence 5相联系，与整段逻辑一致。B：Mercury是traditional planets中最小的，也就是说，Pluto与traditionalplanets的大小相差过大，符合题目要求。其他选项属于无关选项。
32. Which of the followingsentences，if inserted immediately before sentence 6，would providethe most effective transition between the first and secondparagraphs ？
(A)Pluto’s anomaloussize was not the only source of doubt.
(B)This was not thefirst time that a planet’s status hasbeen called into question.
(C)Such scientificdisputes can become surprisingly heated.
(D)The question of who deserves credit for a scientificdiscovery is sometimes difficult to settle.
(E)Many were shockedat the suggestion that Pluto was not really a planet.
答案：A
解析：第一段的Sentence 5提出Pluto受到质疑的一个原因：too small;第二段的Sentence6提出第二个原因：composed ofice。A：size不是唯一质疑，符合上下句;B、C与下文无关;D选项与上下文均无关。此处已经提到了质疑的两方面，E选项中“Pluto有可能不是行星，这个说法让很多人震惊了”，与上下文的内容不符。
33. In context，which of the following is the best revision of theunderlined portion of sentence 7(reproduced below)？
In the 1990s it was discovered that Pluto was justthe largest of hundreds of comet-like bodies occupying a regionknown as the Kuiper Belt.
(A)In the 1990s，however，
(B)In the1990s，bycomparison
(C)Infact，in the1990s
(D) Similarly，in the1990s
(E)Consequently，in the 1990s
答案：C
解析：Sentence 6提出第二个质疑：composed of ice，Sentence 7 Pluto是许许多多的comet-like bodies中最大的，Sentence 7 更进一步说明Pluto与其他bodies相似，从而不能算作planets。AB的转折关系错误;E的因果关系错误，原文没有“因此”这层意思，Sentence 7是事实，不是结论。C的“In fact”符合题目要求。D的similarly：同样地，Sentence 7与Sentence 6没有进行比较。
34. In context，which of the following is the best version of theunderlined portion of sentence 13(reproduced below)?
Clearly they need to resolve the issue ofPluto’sclassification.
(A) (as it is now)
(B)the public needs
(C)something was needed
(D) further observationswere needed
(E)a precisedefinition of planet hood was needed
答案：E
解析：A选项中的的they无指代对象，且need时态错误;B的needs时态错误;C的something表意不清;D、E相比，Sentence14提到了IAU对planet下的定义，所以从上下句看，E选项更符合要求。
35. Which of the following sentences, if placed immediatelyafter sentence 15, would best conclude the passage?
(A)Pluto’s discover,Clyde Tombaugh, had died in 1997 and so did not live to see hisbeloved planet demoted.
(B)Ceres and Pallashad undergone a similar demotion in the nineteenth century whenthey were reclassified as asteroids rather than planets.
(C)Ultimately, then,Pluto was demoted from planetary status not because of its smallsize but because of the clause company it keeps.
(D)This was perhaps the most momentous decision that theInternational Astronomical Union had made in its 87-yearhistory.
(E)Nonetheless,supporters of Pluto point out that it has more moons than Mars,Earth, Venus, or Mercury.
答案：C
解析：总结句的作用有三个：一是重复前句，二是总结本段，三是总结全文。本段提出了definition，Sentence 15提到Pluto不满足第三个条件，C提到demoted(降级)与之呼应，且C的后半句与前文呼应。其他选项都无关。
section 10
1.In1997，theThrustSSC，a British-madecar powered by two jet engines, have become the firstland-traveling vehicle to break the sound barrier.
(A) have become
(B)were to become
(C)becoming
(D) become
(E)became
答案：E
类型：主谓一致
解析：句子的主语是theThrustSSC（三人称单数），因此谓语动词不能用havebecome。ABD都可以直接排除，C选项不能做谓语动词，因此也是错误的。became是become的过去式，可以做谓语。
2. Some of the novels forwhich Laura Esquivel has received the greatest critical acclaimand are examples of the literary style known as magicalrealism.
(A) acclaim and are
(B)acclaim are
(C)acclaim,
(D) acclaim, they are
(E)acclaim, which are
答案：B
类型：句子结构。
解析：句子的主语是some of thenovels，for which…引导一个定语从句，所以后面应该出现句子的谓语动词。andare中的and不能并列has和are，因为has是从句动词。are是主句的动词，A错。B正确，从句结束之后出现主句谓语动词are。C选项缺乏谓语动词。D选项中，someof novels不能做they的同位语（代词不能有同位语），D也错。E选项，两个从句，主句没有谓语动词，E错。
3. Mother’s Day iscelebrated in a number of nations, but the date on which theyfall differs from one nation to another.
(A) on which they falldiffers
(B)on which it falls differs
(C)which it falls on differing
(D)on which they fall is different
(E)which they fallon being different
答案：B
类型：代词
解析：发出fall这个动词的主语应该是Mother’sDay，不能用they来指代，因此可以排除ADE选项。C选项中differing不能做主句的谓语动词，因此C错误。
4. A self-taught artist, the pottery of Lucy M. Lewishas been featured in many museums, including the SmithsonianInstitution and the National Museum of the AmericanIndian.
(A)A self-taught artist, the pottery of Lucy M. Lewis has beenfeatured
(B)A self-taughtartist, they featured the pottery of Lucy M. Lewis
(C)A self-taughtartist, Lucy M. Lewis’ pottery hasbeen featured
(D)The pottery of Lucy M. Lewis, a self-taught artist who hasbeen featured
(E)The pottery ofLucy M. Lewis, a self-taught artist, has been featured
答案：E
类型：同位语
解析：A self-taughtartist在句中充当同位语的角色，同位语必须和它挨着的部分是同一个事物，这里的A self-taughtartist肯定是一个人。因此，我们可以排除ABC选项。D选项没有谓语动词，has是whohas…这个从句的动词。综上选E。
5. The museum acquired a dozenpaintings from two private donors, who were an art historyprofessor at the local university.
(A)who were an art history professor
(B)who was each anart history professor
(C)who were both arthistory professors
(D)both of whom were an art history professor
(E)which were bothart history professors
答案：C
类型：名词单复数
解析：定语从句的先行词是two privatedonors，所以不能用an art historyprofessor来指代。ABD可以直接排除。E选项which使用错误，which不能指人。
6. To attract prey, a fishknown as the red grouper restructures the ocean floor, diggingholes to create the type of environment favored by smaller fishand spiny lobsters.
(A) digging holes tocreate
(B)digging hole creates
(C)digging holes create
(D) it digs holescreating
(E)they dig holes to create
答案：A
类型：非谓语
解析：主句是a fish…the oceanfloor，digging holes做状语，tocreate表目的。原句没有错误。B中creates使用错误，C中create使用错误，digholes与create有目的关系。D和E是run-on句子，都错。
7. Built on the banks of theMississippi River, it is often so humid in the city of Memphisduring the summer that the air feels like steam.
(A)it is often so humid in the city ofMemphis during the summer that the air feels like steam
(B)the city ofMemphis is often so humid during the summer that the air feels likesteam
(C)the city ofMemphis, which is often so humid that the air feels like steamduring the summer
(D)during the summer the city of Memphis is often so humid towhere the air feels like steam
(E)summer in thecity of Memphis is often so humid that the air feels likesteam
答案：B
类型：逻辑主语
解析：built on thebanks…做状语，built逻辑主语必然是句子主语，那么句子主语应该是某种建筑，因此可以直接排除AE。B正确。C只有which引导的从句，没有主句。D中towhere使用错误。
8. Dinosaurs captured thepublic’s attention in the nineteenth century, and the scientistswhich found and will study dinosaur fossils were highlyesteemed.
(A)and the scientists which found and will study
(B)and thescientists who found and studied
(C)the scientistswho found and studied
(D) the scientists findingand studying
(E)also thescientists which found and studied
答案：B
类型：定语从句和句子结构
解析：原句中which使用肯定错误，which不能指人，因此E选项也肯定错。C和D都是run-on句，错。只有B正确。
9. The topography of the OzarkMountains, having been shaped by the dissolution of limestone andother types of soluble rock, feature hundreds of geologicalwonders.
(A) rock, feature
(B)rock, and featured
(C)rock, featuring
(D) rock, features
(E)rock to feature
答案：D
类型：句子结构
解析：句子主语是The topography of theOzark Mountains。having been…是状语成分。主语是三人称单数，所以谓语动词不能用feature。B中andfeatured错误。C中featuring不能做谓语动词。D正确。E中to feature也不能做谓语动词。
10. In the early twentieth century, Modernist novelistssuch as James Joyce and Virginia Woolf experimented with literaryform and narrative technique more than preceding centuriesdid.
(A) more than precedingcenturies did
(B)more than writersof preceding centuries did
(C)more than that inpreceding centuries
(D)to a greater extent than preceding centuries
(E)to an extentgreater than novels of preceding centuries
答案：B
类型：比较
解析：句子是拿Modernist novelists和其他作家比较，than之后的名词必然是与novelists能够对应的，那么符合要求的只有B选项。其他选项比较内容都错误了。

(A) ancestry and using hisfindings

(C)ancestry, he used his findings
(D)ancestry, and he used his findings
(E)ancestry, whose findings were used
答案：D
类型：句子结构。
解析：原句中using没有平行成分，A错。B中，两个并列句，前面用主动，后面用被动，累赘，B错。C是run-on句子，C错。D中and是连词，并列两个完整句子，正确。E改变原句意思，原句中说的是hisfindings，E选项说的是祖先的发现。

(C)world and islocated in eastern China’s Shandongprovince, it crosses
(D)world, it is located in eastern China’s Shandong province, crossing
(E)world; located ineastern China’s Shandongprovince, crossing
答案：A
类型：句子结构
解析：A中，分号的作用类似于句号，分号后面是一个状语+主句的结构，A正确。B和A只有一个标点符号的区别，但是world之后用逗号的话，就是run-on句型了。C也是run-on句子。D仍然是run-on句子。E选项中，分号之后的句子没有主语。
13. Textile production has aserious environmental impact, it consumes a significantamount of all the water used worldwide.
(A) it consumes
(B)its consumption is
(C)this consumes
(D) consuming
(E)it has consumed
答案：D
类型：句子结构
解析：原句是run-on句子，A错。B与A错误类型一致，B错。C有两个错误，一个是this直接用来做主语，第二，C选项也是run-on句型。D中consuming...做状语，D正确。E仍然是run-on句型。

(A) predate that of
(B)predates that of

(D) have predated
(E)predate
答案：B
类型：比较
解析：句子是拿production of cheesesmade from goat’s and sheep’s milk和production of cheese made fromcow’smilk来进行比较，production可以用that指代。另外，production是三人称单数，因此必须用三人称单数谓语动词。因此答案只能选B。
