对不起大家，前一段时间经历了元旦春节忙季都乱七八糟事，没能按时上来汇报进度。复习在缓慢的进行着目前把OG12、OG13结合千行又进行分类总结了一遍，目的是总结常见考点的出题规律。把总结的一些东西放上来和大家分享一下 ，认识还比较浅显，请大牛多指教。 首先是主动和被动的问题。 主动与被动 GMAT 的句子中能采用主动的就不用被动，尤其是从句，避免wordy和歧义。 1.The Glass House Mountains in Queensland, Australia, were sighted in 1770 by the English navigator Captain James Cook, who so named them supposedly because their sheer wet rocks glistened like glass. 选项中“they were named supposedly because。。。”是没有必要的
2. A surge in new home sales and a drop in weekly unemployment claims suggest that the economy might not be as weak as some analysts previously thought. that引导的从句是表明其实economy没有之前想得那么weak。“might not be as weak as some analysts previously thought ”结构清晰，选项中“might not be as weak as have been thought by…”wordy 但在一些特殊情况下，被动是第一选择--------强调事情本身，无关发出者。 The Olympic Games helped to keep peace among the pugnacious states of the Greek world，for a sacred truce was proclaimed during the month of festival. 这个句子表达的是一个因果关系，Olympic Games keep peace的原因是a sacred truce was proclaimed 原文没有体现是谁发出这个动作，也不是Olympic Games发出，所以选项中 “they proclaimed…”的主动形式都是不正确的，they无所指，是凭空出现的。作者: shuhe 时间: 2013-3-5 21:02
But作为连词，和“and“的规则一样，前后结构要平行
1. Sunspots, vortices of gas associated with strongelectromagnetic activity, are visible as dark spots on the surface of theSun but have neverbeen sighted on the Sun's poles or equator.
句子原意是sunspots在哪里能看见，但是在哪里看不见，两者是平行关系“are visible as…”和“have never been sighted…”平行
100.Like the planets, the stars are in motion, someof them at tremendous speeds, but they are so far away fromearth that their apparent positions in the sky do not change enough for theirmovement to be observed during a single human lifetime.
116. Mauritiuswas a British colony for almost 200 years, but expect in the domains ofadministration and teaching, the English language was never really spoken onthe island. 这题同样也是， Britishcolony和neverreally spoken表达的是转折的意思，一定要有but
38.Bengal-born writer, philosopher, and educator Rabindranath Tagore had thegreatest admiration for Mohandas K. Gandhi as a person and as a politician, butTagore was also skeptical of Gandhi's form of nationalism and his conservativeopinions about India's cultural traditions.
admiration for和skeptical of两种相反的情绪，用but
even though和although 19. TheIroquois were primarily planters, although they supplemented theircultivation of maize, squash, and beans with fishing and hunting
未划线部分关键词是“primarily”，说明后面的内容是“尽管 although”尽管supplement …withfishing and hunting，但主要还是planters，强调的是前者，所以不能用but。
31. Eventhough many of her colleagues were convinced that genes were relativelysimple and static, Brabara McClintock adhered to her own more complicated ideasabout how genes might operate, and in 1983,at the age of 81, was awarded aNobel Prize for her discovery that the genes in corn are capable of moving fromone chromosomal site to another.
“complicated”和“simple”相反，推测划线的内容一定是even though或although， Even though+完整句子，although可加短语。
98. Eventhough Clovis points, spear points with longitudinal grooves chipped onto theirfaces, have been found all over North America, they are named for the NewMexico site where they were first discovered in 1932.
Eventhough前后转折的内容是 “have been foundall over…”和 “hey are named forthe New Mexico site where they were first discovered in 1932.”。 其他错误选项转折的内容都有错误。
48.Though called a sea, the landlocked Caspian is actually the largest lake onEarth, covering more than four times the surface area of its closest rival insize, North America's Lake Superior.
Thoughcalled a sea成分是open modifier修饰landlockedCaspian
132.Although heirloom tomatoes, grown from seeds saved during the previous year,appear less appetizing than most of their round and red supermarket cousins—theyare often green and striped, or have plenty of bumps and bruises—heirlooms aremore flavorful and thus in increasing demand.
(A) Althoughappearing less appetizing than most of their round and red supermarket cousins,heirloom tomatoes, grown from seeds saved during the previous year 从原句来看，想表达的是尽管 “heirloom tomatoes appearsg less appetizingthan常见品种”，但是他们“oftengreen and striped, or have plenty of bumps and bruises—heirlooms are moreflavorful and thus in increasing demand.” 作者: shuhe 时间: 2013-3-5 21:48
总结一下OG当中that从句的用法 首先，一大类是that引导的从句对抽象名词的解释 例如hope，expectation，confidence，evidence，hypothesis等，这些抽象名词都不会单独出现，后面一定会跟随that引导的从句阐述内容。所以上述词+of的形式基本都是错误的。
1. Although a surge in retail sales has raised hopes that a recovery is finallyunder way,many economists say that without a large amount of spending the recovery mightnot last.

128.Australian embryologists have found evidence to suggest thatthe elephant is descended from an aquatic animal and that its trunk originally evolved as akind of snorkel. Evidence tosuggest that…and that… suggest引导的两个内容分别用that
97.

3. Althoughvarious eighteenth- and nineteenth-century American poets had professed an interest inNative American poetry and had pretended to imitate Native Americanforms in their own works, it was not until almost 1900 that scholars andcritics seriously beganstudying traditional Native American poetry in native languages. 在began studying之前就已经professed and pretended

Accordingto some analysts, the gain in the stock market reflect growing confidence thatthe economy will avoid the recession that many had fearedearlier in the year and instead come in for a"soft landing", followed by a gradual increase in business activity.
再来看这道题，B选项除了and之后缺少主语之外，语法上是没有错误的，但是除了句意强调“primarily”，还有were planters和supplemented是没有必要放在一条时间线上的，因为were表示的是状态，而不是一个动作，supplement发生在什么时候都不影响他们是planters。所以不一定两个动词出现，就一定要区分先后，还有若出现“after”等明确的表先后的词，可都用一般过去时。 19. TheIroquois were primarily planters, although they supplemented theircultivation of maize, squash, and beans with fishing and hunting
【B 】 and had supplemented作者: shuhe 时间: 2013-3-5 22:59 夹心修饰 1. Althoughvarious eighteenth- and nineteenth-century American poets had professed aninterest in Native American poetry and had pretended to imitate Native Americanforms in their own works, it was not until almost 1900 that scholars andcritics seriously began studying traditional Native American poetry innative languages. A ，until almost 1900，scholars andcritics did not begin… 夹心修饰，不是指放在两个分句中间，而是指可修饰前面，也可修饰后面，造成理解的歧义。 A选项中的untilalmost 1900就是夹心修饰，可前可后，不明确。 修饰成分的位置 5. Diabetes,together with its serious complications, ranks as the nation’s third leadingcause of death, surpassed onlyby heart disease and cancer. Only修饰byheart disease and cancer，而不是修饰surpassed，所以不能放在surpassed前面，不符合逻辑意思。 7.

因为是risinginventories所以对应的是correspondingincreases in sales，而不是correspondingly increased sales 18. Plantsare more efficient than fungi at acquiring carbon, in the form of carbon dioxide, andconverting it to energy-rich sugars.
in the formof carbon dioxide修饰carbon，所以前面只能是carbon 40. Dr. Tonegawawon the Nobel Prize for discovering how the body can constantly change itsgenes to fashion a seeminglyunlimited number of antibodies, each targeted specifically at an invadingmicrobe or foreign substance.

Doing的集中常见用法
第一类是出现在句首，表明主语（动作的发出者）做了什么，就是open modifier
15.Warning that computers in the United States are not secure, the National Academy of Sciences has urged the nation to revamp computer security procedures, institute new emergency response teams, and create a special nongovernment organization to take charge of computer security planning.

79. Defense attorneys have occasionally argued that their client's misconduct stemmed from a reaction to something ingested, but if criminal or delinquent behavior is attributed to an allergy to some food, the perpetrators are in effect told that they are not responsible for their action.
原句“in attributing criminal…”在but 引导的句子中，显然是open modifier “the perpetrators”不和逻辑
第二类，表前面句子产生的结果
21.Retail sales rose 0.8 of 1 percent in August, intensifying expectations that personal spending in the July-September quarter would more than double the 1.4 percent growth rate in personal spending for the previous quarter.
37.Emily Dickinson's letters to Susan Huntington Dickinson, which were written over a period beginning a few years before Susan's marriage to Emily's brother and ending shortly before Emily's death in 1886,outnumber her letters to anyone else.
原句“were written over…”是主句，“outnumberingher letters to anyone else”表结果，是不正确的，两者没有automatic and essentially unavoidable consequence
47.Five fledgling sea eagles left their nests in western Scotland this summer, bringing to 34 the number of wild birds successfully raised since transplants from Norway began in 1975.
“Five fledgling sea eagles left…”导致了number的上升
59.The Olympic Games helped to keep peace among the pugnacious states of the Greek world，for a sacred truce was proclaimed during the month of festival.
选项B“proclaiming a sacred…”不符合逻辑意思，因为主句是说奥利匹克helped to keep peace，后面的内容显然是解释怎么help，是因果关系，用doing是本末倒置。
65.In a plan to stop the erosion of East Coast beaches, the Army Crops of Engineers proposed building parallel to shore a breakwater of rocks that would rise six feet above the waterline and act as a buffer, absorbing the energy of crashing waves and protecting the beaches.
“absorbing …and protecting…”是前面“would rise six feet above the waterline and act as a buffer ”产生的结果，也可以理解为对buffer作用的补充。
78.Fossils of the arm of a sloth, found in Puerto Rico in 1991, have been dated at 34 million years old, making the sloth the earliest known mammal on the Greater Antilles Islands.
“making”表示前面的事实带来的结果，其他选项中“made”不符合逻辑，fossiles不能made sloth known

111. A mutual fund having billions of dollars in assets will typically invest that money in hundreds of companies, rarely holding more than one percent of the shares of any particular corporation
1.The Glass House Mountains in Queensland, Australia, were sighted in 1770 by the English navigator Captain James Cook, who so named them supposedly because their sheer wet rocks glistened like glass.
选项C“naming them supposedly…”是修饰前面整个句子的，不合逻辑，不能明确动作的发出者，也不能体现出是在过去时间点发出的动作。
第三类补充说明/表状态或伴随
19.The Iroquois were primarily planters, although they supplemented their cultivation of maize, squash, and beans with fishing and hunting
124.Found throughout Central and South America, the sloth hangs from trees by its long rubbery limbs, sleeping 15 hours a day and moving so infrequently that two species of algae grow on its coat and between its toes.
Hang sleep 和move三个动词显然不是并列关系，sleeping和moving是表示hang时候的状态。
134.Recently implemented "shift-work equations" based on studies of the human sleep cycle have reduced sickness, sleeping on the job, and fatigue among shift workers while raisingproduction efficiency in various industries.
While引导的状语从句
48. Though called a sea, the landlocked Caspian is actually the largest lake on Earth, covering more than four times the surface area of its closest rival in size, North America's Lake Superior.
87. According to scientists who monitored its path, an expanding cloud of energized particles ejected from the Sun recently triggered a large storm in the magnetic field that surrounds Earth, brightening the Northern Lights and possibly knocking out a communications satellite.
第四类，修饰名词
21.Neuroscientists, having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, are now drawing solid conclusions about how the human brain grows and how babies acquire language.
再看选项D和E“ have amassed”变成了句子的谓语，“are now drawing”变成了“drawing”若理解为伴随，从逻辑意思和时态上都是不正确的因为主句是have引导的完成时。
而且Neuroscientists,现在做的“drawing solid conclusions”和之前的“having amassed a wealth of knowledge”没有automatic and essentially unavoidable consequence，所以也是不正确的。
30.For members of the seventeenth-century Ashanti nation in Africa, animal-hide shields with wooden frames were essential items of military equipment, protectingwarriors against enemy arrows and spears.
Protecting前面的句子是系动词，所以既可以认为是修饰主语也可以认为是修饰宾语，因为两者相等的，这里用Protecting准确的补充说明了animal-hide shields的功用，“to protect”用在逗号后表目的，与前面“A is B”多表达的内容不符。
42.Scientists have recently discovered what could be the largest and oldest living organism on Earth, a giant fungus that is an interwoven filigree of mushrooms and rootlike tentacles spawned by a single fertilized spore some 10,000 years ago and extending for more than 30 acres in the soil of a Michigan forest.
“an interwoven filigree of mushrooms and rootlike tentacles”的核心词是filigree，“spawned… and extending…”都是修饰filigree，doing表示extend持续到现在。
66.The 32 species that make up the dolphin family are closely related to whales and in fact include the animal known as the killer whale, which can grow to be 30 feet long and is famous for its aggressive hunting pods.
B选项“growing as big as”错误的修饰了The 32 species。
95.The peaks of a mountain range, acting like rocks in a streambed, produce ripples in the air flowing over them；the resulting flow pattern, with crests and troughs that remain stationary although the air that forms them is moving rapidly, is known as "standing waves".
“acting like rocks in a streambed”修饰The peaks of a mountain range
103.Yellow jackets number among the 900 or so species of the world's social wasps, wasps that live in a highly cooperative and organized society consisting almost entirely of females--the queen and her sterile female workers.
“consisting almost entirely of females”修饰society。“highly cooperative”，“organized”和“consisting”并列
133.Last week local shrimpers held a news conference to take some credit for the resurgence of the rate Kemp's ridley turtle, saying that their compliance with laws requiring turtle-excluder devices on shrimp nets is protecting adult sea turtles.
表示法律法规的具体内容用doing
7. The intricate structure of the compound insect eye, with its hundreds of miniature eyes called ommatidia, helps explain why scientists have assumed that it evolved independently of the vertebrate eye.
原句中“The intricate structure of the compound insect eye, having hundreds of miniature”产生歧义，不知是structure having 还是 eye having
65. Digging in sediments in northern China, scientists have gathered evidence suggesting that complex life-forms emerged much earlier than previously thought
，这样不好。要积极调整心态。
目前把OG12、OG13结合千行又进行分类总结了一遍，目的是总结常见考点的出题规律。把总结的一些东西放上来和大家分享一下 ，认识还比较浅显，请大牛多指教。
