以下这些是准备SAT时在做题中总结的一些题目，一共67道，来自OG，Princeton Review，Kaplan等书籍。由于字数问题，我实在没时间将所有选项写上，只能放上正确的答案。后面附上点评，算是我自己的理解。有的点评估计没什么道理，自己可以理解，但是不“正规系统“。所以实在不行也可以把正确答案当作结论记住即可。说实在话，SAT语法部分的单句替换的题型有限，大家要多注意总结。时间一长就会发现出来出去无非是那十多种。一下我选的这些题比较容易出点错。太简单的我就没有列了。为了节约时间，对无关意思的名次如人明，组织名，地名在句中采取了首字母大写。由于记录时间离现在比较远，而且当时字写得比较草，加上打字中可能出现的错误，题目也许出现问题，但应该不会妨碍阅读，请见谅。欢迎来挑错。
错误基本已修正，感谢leowtyx同学在申请百忙中的建议和修改！

1.The choreographer Katherine Dunham having trained as an anthropologist,she studied dance in Jamaica,Haiti,and Senegal.
Katherine Dunham,who was also a trained antropologist,studied
点评：K是一个编舞家，同时又学过人类学。所以用…also…结构。同时K作为主语，通常放在句首，后接一个句，再接谓语。在描述某人时正确语序经常如此。
2. Weight training was begun by the girl to enhance her strength and flexibility.
The girl had begun the exercise of weight training to enhance
点评：搭配不当。因该是”begin exercise” 放入句中，用过去完成时。同时注意主语最好放在句首，一般勿倒装。
3．One of the most common types of mistakes that inexperienced drivers make is failing to signal for a lane change;another one that occurs about as frequently is exceeding posted speed limits.
点评：Right! 首先，检查主谓一致性，无误。由于前面是一个句子，后面也是一个句子，为避免Run-on，应用分好隔开（两句无因果关系）。同时注意”another”和”another one”用法。
4. Although talent may be a crucial element on the road to fame,it is difficult to succeed without a highly developed work ethic.
without a highly developed work ethic,succeeding is difficult.
点评：目前不知道为何这样改，大家研究一下。但又数个同类型题都如此，经验就是形如“Although…另一个东西也必要”后一定要按意思届一个“without”而不用“It is…”
5.(常考题：转折) Some taxpayers knowingly violate IRS regulations when filing their tax returnes,in other respects they are law-abiding citizens,however.
Some taxpayers who are otherwise obedient citizens knowingly violate IRS regulations in their tax returns.
点评：首先注意意思，应为：尽管一批人在其它方面守法，但在某一方面却知法犯法。最好将主句放在最前，用顺叙。这个极重要，因为可以看出在许多题中顺叙比倒装好。
6. Although my alarm clock did not go off,causing me to arrive no more than ten minutes late.
it did not cause me to arrive more
点评：对于这种“Although…”的形式，几乎所有正确答案都将逗号后的句子的主语放在前面，组成一个顺叙句。
7. Eating foods rich in carbohydrates before a race is common among marathon runners,all of them need reliable energy sources for peak performance
of whom need
点评：注意主语
8．Los Angeles’s freeways,usually busier and more crowded than those of other cities,are clogged almost twenty four hours a day,contributing to the city’s pollution problem.
Right!
点评：首先，无论指代，主谓还是时态，本句没有问题，且又是顺叙，直接用“Los Angeles’s freeways”而不用“the freeways of Los Angeles”，所以是正确的。
9.（常考题：修辞对象）Set in the sixteenth century,modern audiences enjoyed the contemporary opera Galileo Galilei written by Philip Glass.
century,Philip Glass’s contemporary opera Galileo Galilei has enjoyed great success with modern audiences.
点评：注意形容的对象和形容的部分要相邻为好，同时注意顺叙，用“Philip Glass’s contemporary opera”而不是“the contemporary opera Galileo Galilei written by Philip Glass.”
10. Whenever television is denounced by viewers for its violence, they call on the department of standard and practice to take action.
Whenever viewers denounce television for its violence,they call
点评：这样改使句子十分完整，谁“denounce”？是“viewers”，且viewers call…for practice. 同时还是要强调顺叙，不要用被动态。主语为“viewers”而不是“television”
11. Toward the end of the 1990s,it became clear that Internet-based companies were overvalued in the stock market,since such is the case,their stock prices have dropped considerably in recent years.
and consequently their stock prices have dropped considerabley in recent years
点评：这一类语句表因果。很多错误选项都在后面届一个句子并以“because of that”，“as a result”，“for this reason”。其实都不对。直接用“consequently”顺接表结果。像“as result”一般中间应用分号隔开。
12. （常考题：转折） Abraham Lincoln is frequently lauded as a successful politician,and his early political career was dominated by a string of lost elections.
Although Abraham Lincoln is frequently lauded as a successful politician,
点评：这一类语句表转折，故要有转折词。“however”一般前有分号或后用逗号相联系（句首除外）。“Inasmuch”太繁。故常用Although，用逗号和下半句相连。
13．The romance between Yum-Yum and Nanki-Poo accounts for the lasting appeal of the Mikcado,as do Gilbert and Sulliran’s singable tunes and clever lyrics to…
accounts for the lasting appeal of the Mikado,as do
点评：动词用复数形式。
14．Confession of violent crimes nationwide skyrocketed last year,but in some towns they remained steady or decreased.
but in some towns such confessions
点评：该句错在指代不明。“they”不知是指“confession”而是指“violent crime”。故而后半句需要说明。如果一个句子中谈到了多个名词，一定要注意代词。
15．Televisions themselves have become more affordable,but VCRs,DVD players,and monthly cable bills influence the total monetary price to increase greatly of home entertainment.
greatly increase the total price
点评：整齐简洁明了，同时符合习惯用法。
16．When the students take a trip on the intracoastal-waterway system next month,they will learn facts with which they have heretofore been unacquainted.
Right!
点评：倒装语句，其实在这种状况下无妨，具体为何我。。。不清楚。但也有多个类似题目大家可以在平时发掘，实在不行就死记。且有being在句中的选项经常是错的。
17．Even though California is smaller than Alaska or Texas it has a far larger population.
Texas,California has by far the largest population.
点评：首先防止Run-on。其次注意到Alaska和Texas中间是“or”，所以代词“it”的指代对象需要说明，将它直接换成“California”。
18．In June,Juile was certified in CPR and aquatic rescue,and she has been working as a lifeguard ever since.
Right!
点评：这也是一种题型，死记吧。。。某人在做完某事后一直做某事：Sb has been working as…ever since…
19. One of the most unusual animals in the world,eggs are laid by the platypus,which is also a mammal.
the platypus is a mammal that also lays eggs.
点评：platypus是动物，不是人，不能用Who，同时将被修饰成分和修饰语放在一起。
20．The unique culture of Cork is primarily founded by its great musical and lyrical traditions.
Cork has a unique culture founded primarily on
点评：又体现了最好还是用顺叙这个原则。
21. Having an exceptional beautiful mountain range and heavy winter snowfall,the International Olympic Committee choose Salt Lake city as the site of the 2002 Winter Olympics.
Because it has an exceptionally beautiful mountain range and heavy winter snowfall,Salt Lake city was chosen by the International Olympic Committee
点评：一种常考题型，因果关系的反映。由于Because的后面的it指Salt Lake city,故后半句主语开头必为Salt Lake city。
22．The marathon runner’s early burst of speed had been exciting to some,she was slower after several miles.
had been excitihg to some;however,she was
点评：句子语气其实也是这种题的关键之一。该句表转折，且是向不好方向转折，前面没有Although等。所以在句中用“however+分号”，呵呵，放之于四海皆准的真理。
23．（常考题：对比）The annual income of the average African citizen is 211 dollars,the average American’s income isalmost 27591 dollars.
dollars,yet the average American’s income is
点评：对比题，所以要体现对比的语气。原句run-on了.所以正确答案中间用了yet这个词（和however差不多）。记住此类题，比较常考
24．Although the CWS win more often than the CC,Chicago residnets,who are historically mid(此处不清晰) baseball fans,prefer the CC。
Right！
点评：使用正常的语序
25．Because the lens have UV protection,nearly all UV rays are prevented from reaching the wearer’s eyes.
protection,they prevent nearly all UV rays from reaching the wearer’s eyes.
点评：prevent sth/sb from doing sth. 老句型了。。。同时注意主语为lenses,所以直接用they。一般用主动态多余被动态（“顺”比“逆”好）
26. The hills in SBC,like neighboring SLOC,is the home to some of C’s best vineyards.
the hills of neighboring SLOC,are
点评：hills要和hills对比才对称，be动词用复数。“of neighboring”这个用法可以记一下。
27（常考题：并列）Nurses and anesthesiologists are both essential in the operating room,and the anesthesiologists would keep the patient sedated while the nurses would assist and support the surgeon.
the anesthesiologists to keep the patient sedated and the nurses to assist and support
点评：anesthesiologists和nurses为并列关系，所以用“…to… and…to…”避免run-on。记住这种形式，考得比较多，大家做题时多注意类似题目
28．The sausage served at the end of the meal was more flavorful than any of the other pastas I had tasted;probably because it was roasted in its own juices.
was more flavorful than any of the pastas I had tasted,probably because
点评：pastas不是sausage，故谈到pastas用“any of pastas”不用“any other”。由于后半句谈原因，所以和前面是有联系的，中间用逗号。
29．When a bacterial culture is handled in an environment that is not appropriately sterilized,they can be introducing new organisms,ruining the culture.
When a bacterial culture is handled in an environment that is not appropriately sterilized,new organisms can be introduced,ruining
点评：对这个题我比较无语。。。。。。
30．The hawks’ nest,wedged into an apartment building’s facade,was a rather unique sight in Chicago;they became such an attraction that several book were written about them and tourists came from all over the country to see them.
the hawks,after several books were written about them,became such an attraction that
由于最后代词是“them”，可见所指为复数名词。而第一句主语为nest, 所以可见第二局主语不是网而是鹰。故正确答案不用代词为主语，而是将“they”指明，换成“hawks”
31．（常考题：并列）The major complaints professors have about teaching is that they have challenging research to complete and must also work hard to hold student interest.
are that they have challenging research to complete and must also work hard to hold student interest
点评：主谓一致性要保持，同时使用并列结构。
32．Having achieved fame, widespread acclaim,as well as continued relevance,DS is considered to be a classic American movie.
Having achieved fame,widespread acclaim,and continued relevance
点评：用动名词“Having”没错。但能用and就不用as well as(这似乎又是一条规律)，and前有无逗号无所谓。
33．For as many as 9 months or more,Thad Carthart lived in Paris.
For more than 9 months
点评：不说了，简洁为上！九个月或九个月以上就是“九个月以上”
34．Many home owners in the northern states use a window sealant,for it will prevent heat loss in the winter.
that will prevent
点评：谈原因，从句有时候更简洁。
35．The runners coming this far,they decided to push through the very strenuous final mile of the marathon.
Having come this far,the runners
点评：记住这个句式，Having done sth,XX…不是说它有知识上的意义（大家肯定早就知道了），只是说它正确的频率相当高。同时原句没有转折语气就不要用转折词。
36. Some of the classes taught in American classrooms are interpretations of lessons used worldwide,particularly those in European history.
classroom,particularly in European history,are interpreations of lessons used worldwide.
点评：注意指代对象
37．Joann,the newest student at Leon Blum high school,has been portrayed as the brightest student and also the most unruly of them.
the brightest and yet the most unruly of students.
点评：记住吧。。。the brightest and yet the most unruly of students，后面还有一道关于老虎的题也差不多。
38．Ann’s parents explained that she was promoted to hear journalist for the reason that her articcles were mindful always for both side of the issue.
because her articles were always mindful of both sides of the issues
点评：表原因最好还是用简洁的表达方法，如“because”，“since”等单个词而不是如“for the reason that”等结构。简洁
39．（常考题：转折）Many wealthy taxpayers pay less than ten percent of their annual incomes to the government,some middle-income taxpayers pay a much larger percentage annually.
Although many wealthy taxpayers pay
点评：转折句，富人少给，较穷人多给，故用“虽然。。。但是。。。”SAT题中很多都谈到这种“不公平”现象。改的时候一般在前就用Although，在后就用yet。（和那个非洲人和美国人收入题类似）
40. OW was almost as brilliant a novelist as he was at writing plays.
almost as brilliant a novelist as he was a playwright
点评：并列结构，故前后都因该用职业（名词）。所以说要考虑对比/类比双方的一致性。
41．Examining the catalogue,the phrase “while supplies last” and “get it while it’s hot” are designed to encourage consumers to order the product immeidately.
one sees that the phrase
点评：注意动作的执行者。Examing后面必须对应一个能去Exam的主语。
42．In professional soccer,players kick the ball sharply and accurately;however in other sports their technique is not quite so effective.
Right!
点评：呵呵，每一行都有每一行的门道。转折关系用转折词。
43．The changing color of autumn leaves has a unique fascination for those people which have an understanding of life-cycles in them..
who see the life cycles in them.
点评： “see”也有“理解”的意思,直接用动词更简洁。同时，修饰“people”用who而不用which。
44．It was primarily when I visited the seashore that I felt nostalgic for my childhood home,growing up on a small island.
as I had grown up on a small island
点评：后面的部分是说明自己童年的情况而不是修饰home的。
45．Before 1988,the CBD included 153 menbers,none of the member were women.
members,none of whom were women.
点评：原句run-on了，所以后面不能是一个完整句子。同时“none of 一群对象”后面谓语用复数。
46．Although talent may be a crucial element on the road to fame,it will be difficult to get very far without a highly developed work ethic.
Right!
点评：正确！这个句子前面出现过，不过考察方向不同。这种句式“Although…is important”，后面常用“it is…to…”不用比较级，除非有对照物。
47．The DOS argued that although the U’s professors have raised students’ interest in continuing in academic study,the failure is in their not preparing the students for the real word outside of textbooks and caculators.
they have failed to prepare
点评： 有Although表转折的句子转折之间后面的一般和前面的句式一样，时态相同（haver raised 与 have failed）
48．MO collected the anecdotes and memories of his family in C, his native country,and these are stories that are toldin his memior.
Told these stories
点评：注意平行结构和动词时态即可。不要被句子中的两个名词性成分（anecdotes and memories of his family in C，his native country）迷惑，其实还是收集和讲述（collected和told）。
49．The PC that was being mediated by the president,but now the countries are adamently refusing to compromise their positions.
The president had mediated the PC,but the countries are now adamently refusing to compromise their positions.
点评：注意时态。过去已经调停了，但国家之间又开始争斗起来了。而且用主动而不用被动。
50．By the time IGFCTYFN,my brother has practiced law for five years.
will have been practicing
点评：By the time后用的是现代时（网打上去了，这里挺重要的。。。），所以用将来完成时。
51．The OT’s increased capacity allows divers to discover new species that congregate and feed close to the bottom of the ocean.
Right!
点评：呵呵，我也不知道该怎么评，对的就是对的么（汗一个。。。。。。）
52．（常考题：虚拟）If the concert had begun later,the conductor might have succeed in giving the difficult last –minute correction for the symphony to the orchestra.
Right!
点评：这种形式的题很多，记住就可以了。“If…had/have done sth,…would/might have done…”
53．The domestic cat of which there are more than 40 breeds,is a member of the feline family.
Cat,of which there are more than 40 breeds
cat,of which there are more than 40 breeds
点评：说明一个事物中间插入修饰时，注意修饰方法（倒装等）如“of which”
54．It is hard for me to imagine that 100 years ago this area was undeveloped swamp land,but it has since become high-rise apartment buildings.
land that has since become high-rise apartment buildings
55．The state of NJ is one of he smallest states in the union,being also the most densely populated.
although one of the smallest states in the union,is
点评：这种题超多，讲如一个地方人口地方小但人口密集看上去是因果实际是转折（小地方确人多）。故用“Although…,is…”同时记住一点：这种题中带“Being”的选项90%以上都是错的。
56． Airline such as R and E are able to find alternative,cheap landing strips and are therefore able to pass saving on to their customers.
Right!
点评：主语为Airline，后面就不要再改换了。直接用动词顺接下去即可。
57．U and T schools offer teenagers the opportunities to start working as electricians,plumbers,auto mechanics,and other jobs immediately after graduation.
and in other jobs
点评：注意work as(某职业人士)和work in XX job (职业名称)的不同搭配。
58．Fear prevents some people from speaking out against wrongdoings;ignorance,others;a lack of morality,only a few.
Right!
点评：这种形式似乎不多见，但其实是对的。并列结构很重要。如果实在不习惯句式那就依靠这个原则判断。
59．SAP often involve a semester spent with a host family which they can experience the local way of life firsthand.
during which they
点评：“they”不知道指谁，故直接换为“students”。“which”指“semester”，故前加“during”。这种指代问题，千万小心。
60．Doctors now realize not only that cholesterol hardens the arteries,but also that it increases the risk of heart attack.
Right!
点评： 平行结构问题。“not only do…but also do…”和“do not only…but also…”相似但其实不同。注意位置。
61．Although we were opposed to the program,we thought that despite its bilateral support,it would accomplish a little.
We opposed the program,despite ites bilateral support,because we thought it would accomplish little.
点评：句子原意为“尽管该计划如何如何好，我们反对它，因为。。。。。。”先弄清句意。表原因还是用更简单的“because”。
62．The tomatoes at this fruit stand are much more plump,fresh and tasty than the fruit stand located in the lobby of the building in which I work.
much more plump,fresh and tasty than those sold at the fruit stand located in the lobby of the building.
点评：这个句子中比较了多个项目。在多个比较中可以用“much more/less adj+adj+adj+...”的形式。同时注意比较的对象（西红柿和西红柿比）。
63．While several baseball teams have tried to supplant the Yankees as the dominant team in baseball,their inability has been unable to win even half as many WS as the Yankees have won in the past one hundred years.
they have been unable
点评：平行结构，时态，句式一致。
65．The U tiger,a relative of the B tiger,has been described as the strongest tiger and also the most peaceful of them.
the strongest and yet the most peaceful of tigers.
点评：和前面一题类似。
66．The price of gold has been influenced by continued inflation and because people have lost faith in the dollar.
loss of faith
点评：平行结构。
67．If we compare the number of alligators with the Gila monsters over time,we see that the alligator is in decline.
A comparison overtime of the numbers of alligators and Gila monsters shows that alligators are
点评：直接用“comparison”更简洁。同时还是要（老问题了）注意比较的对象。数量必须和数量比。
