众所周知，SAT考试的题目是会不断重复的：只要你题刷得足够多，到了考场上遇到的总有原题，运气好的时候一半以上都是原题，运气差的时候也有个15%左右。这也就是为什么官方总是严防死守，每次都把自己考试的真题看得严严实实，一般人很难拿到——这是最初的问题。
众所周知，中国人最擅长自己创造问题。很多教SAT的老师或者机构弄不到SAT的真题，但是有智商的考生和家长都知道真题重要，那怎么办的呢？于是他们就开始自己编题，硬说是真题；或者从网上下载练习题，伪造成真题的样子；甚至把往年的真题改一两个字，说是今年的真题。这就成了第二个问题。
众所周知，中国人坑自己人是没有下限的。平时给自己的学生练自己编的假题，做网上下载的练习题，这样的机构只要能生存下来，我们就觉得合理；毕竟出国留学的消费者里，也混进了不少的傻子。但是从今年开始，有一批人开始拿着自己编的真题或者用往年的真题，在SAT考前一天开卖，硬说是“明天考试的题”。好家伙，把白糖当白粉卖，抓不住毒枭无情，抓住了治安拘留是吧？
语法
借助本次SAT语法考试，我们讲一下SAT语法真题重复的基本套路。最常见的第一种就是考点，题型的完全重复。这种考题有经验的老师是可以考前直接预测到的，毕竟大家考前会错的难题也就那么几个，造型奇特的题目也就那么几个，根据官方的出题尿性，出得“好”的题是不会只用一次的，比如这次考试里的：
Drought avoidance mechanisms—morphological adaptations that plants undergo when exposed to drought conditions—take a variety of forms. The soybean plant elongates its primary root to increase water ______ in the rosemary plant, drought triggers a decrease in the plant’s stalk length that limits water lost.
Which choice completes the text so that it conforms to the conventions of Standard English?
A) uptake, for instance, while
B) uptake; for instance,
C) uptake. For instance, while
D) uptake, for instance,
此题和我们考前预测文本里面的这个题目：
大家注意看选项，可以说是一模一样。
当然答案也是出奇的一致。在考前预测文本里的这个题，我们选择D。类似的，真题中的这个题，我们选择A）uptake, for instance, while相信考前看过我们难题汇总的同学应该对这个题记忆犹新，这里就不多赘述了。
另外一种就是文本内容完全重复，让人觉得似曾相识，但是第二次考的时候，考点已经完全变了，让人防不胜防，这种题目专克“背题党”。
本次考试的这个题：
Nineteenth-century Modernista architects championed nature in their designs; granted, the wavy stone fagade and ornate floral tilework of Casa Batlló, a Modernista private home designed by Antoni Gaudi, couldn't exactly grow in a forest. _______ one sees natural influences in Gaudi's penchant for curves (rather than right angles) and plant-and animal-inspired flourishes.
Which choice completes the text with the most logical transition?
A) Similarly,
B) In other words,
C) Furthermore,
D) Still,
相信大家考前刷过题的宝子们对这个题绝对不陌生，这熟悉的championed nature，这熟悉的couldn’t exactly grow in a forest——毕竟这是是我们重点讲到的题目。但这次选项里面没有我们熟悉的of course，因为这次空出在的后边，逻辑应该是让步，所以应该选D。
当然，每次考试都会有一些新考点，本次考试也不例外，只不过这次的新考点实在是过于简单，以至于看起来像个“假题”，新考点be like：
In 1909, children in the US were introduced to Billy Possum, a stuffed toy opossum named after the newly elected president, Wiliam Taft. _________ by the entrepreneur Susie Wright Allgood, Bily Possum was promoted as a replacement for the popular teddy bear, which was named for the previous president, Theodore Roosevelt.
Which choice completes the text so that it conforms to the conventions of StandardEnglish?
A) Invented
B) Invent
C) lnvents
D) ls invented
我和我的小伙伴都看笑了，选A就不提了，主要是这么傻的题在考场上真不敢选啊。
考完学霸说难，难不一定难，但一定很怪
本次语法考试总的来说考点重复率依旧无限接近100%。新考点并无挑战，相信只要考前认真刷过题，理解了母题精髓的朋友会觉得毫不费力。

整体基调：全题库题量正常，不再是1000题，而是正常的500-600题。M1部分重复率还不错。但M2整体旧题重复率不足10%，CB题库扩容已成常态，纯靠刷题背题的路基本走不通。
看看100%纯种重复：
A student is writing a research paper on the history of irrigation in the southwestern United States, situating the development of the Salt Spring Valley Reservoir (a man-made body of water created in Calaveras County, California, in 1882) in a larger historical context. The student claims that some modern-day irrigation methods used in southwestern states, such as California, Arizona, and New Mexico, have a lineage that long predates the completion of the Salt Spring Valley Reservoir.
Which quotation from a historian best supports the student's claim?
A) “In the decades following the Second World War, irrigation of arid areas for agriculture increased to such a degree that it now accounts for roughly 70% of the world’s water usage.”
B) “The importance of the development of irrigation infrastructure in the American Southwest today cannot be overstated, since it is the most common means of conveying water for food production.”
C) “The irrigation system developed by the Hohokam people in what is now central Arizona in the 7th century CE was simple but made use of hydraulic engineering design principles that are still utilized by today's engineers.”
D) “Sprinkler irrigation systems, which were developed in the late 20th century, are a convenient technique of irrigating that makes use of machinery in order to spray water in all directions. Many areas of the Southwestern United States are currently irrigated by this method.”

其他的最多算个眼熟，实质区别堪比整容：
Asia's Gobi Desert and California's Central Valley are the main sources of dust in western North America's Sierra Nevada mountains. To investigate their relative contributions, Sarah Aciego et al collected and recorded the isotopic signatures of dust collected at a low-elevation site (the San Joaquin Experimental Range) and two higher elevation sites (Providence and Soaproot) in the Sierra Nevada, as well as the isotopic signatures of Gobi and Central Valley dust. Aciego et al. concluded that while the contribution of Central Valley dust, which has a lower ratio of strontium-87 to strontium-86 (87Sr/86Sr) than Asian dust does, remained mostly unchanged at the lowest-elevation site for the duration of the study, the contribution of Central Valley dust increased at the higher elevations.
Which choice best reflects the researchers’ conclusions?
A) Over the course of the study, the 87Sr/86Sr ratio of dust collected at the San Joaquin Experimental Range was relatively constant, whereas the 87Sr/86Sr ratios of dust collected at Providence and Soaproot decreased.
B) As the study went on, the 87Sr/86Sr ratios of dust collected at Providence and Soaproot grew closer to the 87Sr/86Sr ratio of dust from Asia, whereas the 87Sr/86Sr ratio of dust collected at the San Joaquin Experimental Range grew closer to the 87Sr/86Sr ratio of dust collected in from the Central Valley.
C) Throughout the study, the 87Sr/86Sr ratio of dust collected at the San Joaquin Experimental Range was consistently higher than the 87Sr/86Sr ratios of dust collected at Providence and Soaproot.
D) By the end of the study, the 87Sr/86Sr ratios of dust collected at Providence and the San Joaquin Experimental Range had become very similar, whereas the 87Sr/86Sr ratio of dust collected at Soaproot.

或者这样的：
Text 1
...of Nemesis and The End of Eternity, is highly regarded despite his mediocre writing style. His prose is workmanlike; his characters are flat and discuss ideas rather than emotions. That his work is enjoyable despite this is a testament to his prodigious imagination—even if people read his books only for the ideas, they will have plenty to consider.
Text 2
Asimov is critiqued for his style, but it is wrong to fault a writer for failing to do what he never intended to do. For example, although most of his novel Foundation consists of people discussing science and politics and we find out little about his characters' lives, Asimov wanted to convey the vast sweep of human history over centuries, and one of his points is that at such a timescale, individuals don't matter. Thus his lack of characterization is central to Asimov's thematic aims.
Based on the texts, how would the author of Text 2 most likely respond to the evaluation of Asimov's writing style in the underlined claim in Text 1?
A. By arguing that Asimov's writing style should be judged against the styles of historians rather than those of fiction writers
B. By pointing out that the flatness of Asimov's characters is a feature of Nemesis and The End of Eternity but not of Foundation
C. By agreeing that Asimov's prose is flawed but disagreeing about the quality of his characters
D. By asserting that Asimov's minimal characterization is likely a conscious choice that helps him convey an important idea

但是面目全非
难题部分基本全是新题，且维持高难度。M1首次出现卡人题，开局就不能松懈。高难度题型集中在长链条推理、文本证据题，古典/戏剧文本回归成为主要难点。M2后半段信息密度大、耗时长，时间压力非常突出。
Silica cements associated with casts of soft-bodied marine organisms from the Ediacaran period (circa 538-635 million years ago) are plausibly attributable to one of two phenomena: rapid postmortem preservation of the organisms via precipitation of cements from silica-rich oceans or cement precipitation via high-pressure reactions long after the organisms were preserved by some other means. Recognizing that such reactions generally result in cements with germanium/silicon (Ge/Si) ratios lower than those of silica grains recovered from the same portion of sandstone, Lidya Tarhan et al. investigated silica cements and grains associated with Ediacaran soft-bodied casts at a site in South Australia.
Based on the information in the text and the graph, Tarhan et al. could most reasonably draw which conclusion?
A) The distribution of Ge/Si ratios indicates that a portion of the cements could have precipitated via high-pressure reactions, which suggests that organisms at the site were less likely to have been preserved via rapid precipitation from a silica-rich ocean than Tarhan et al. hypothesized.
B) The total number of cement samples is much lower than the total number of grains precipitated via high-pressure reactions, which suggests that rapid precipitation from silica-rich oceans could account for the preservation of the site's organisms.
C) The range of Ge/Si ratios is larger for the cements than for the grains, which suggests that the cements are likely the result of high-pressure reactions that occurred long after the organisms were preserved by some other means than precipitation from a silica-rich ocean.
D) The distribution of Ge/Si ratios of the cements and grains is largely inconsistent with the cements having precipitated via high-pressure reactions, which implicitly lends support to the idea that the organisms at the site were quickly preserved by cement precipitation from a silica-rich ocean.
