前言
看一家饭店会不会倒闭，最快的一个方法就是看它还有没有新花样：这里的新花样可以指新菜，新装修，新服务员，新厨师，甚至一把新椅子。当一个饭店铁定走在关店的路上时，老板的第一个选择就是大脑关停，活一天是一天。
往往这个时候，曾经越辉煌，在关店的时候看起来就越落寞。
我们作为15年的SAT老教师，也是曾经见证过10月考场人山人海的年代的。那个时候无论是香港，澳门，还是新加坡，甚至越南，泰国都遍布着中国准留子们，甚至有一些颇为自豪的高中生，穿着自己学校红白相间的校服穿梭在考场里，默默炫耀自己“中国第一高”的地位。
曾经的香港亚博“万人坑”
而今天再看，10月的SAT似乎已经成为了历史。从曾经那个留子们专属的“高考月”，变成了一年中并无特殊含义，甚至少人参加的考试。
正如我们开头举例的那样，10月SAT考试也因为走在明显的下坡路上，M1题目变得重复率高，没惊喜，到处都是换皮怪。往年重复重灾区的语法部分更是夸张，甚至出现了收录到OG官方指南的题目和文本。以往引以为傲的AB套出题这次也变得乏善可陈，经过题库查重之后发现，所谓的AB套有大量题目重复。
但同时M2又非常离谱的难做。词汇题到达了GRE级别：convoluted/ derivative/ inadvertent/ arbitrary/ divulged/ exonerated/ encroached on /abstained from/incipient/ profuse/ attenuated/ ambivalent。
阅读只要到了第6开始就已经难得做不下去。又重复又难，又快乐又痛苦，CB真的是人性拿捏者。
语法
首先我们看一个题：
While researching a topic, a student has taken the following notes:
·The Mohs scale of mineral hardness is a ten-point scale that orders minerals by hardness based on their ability to scratch other minerals.
·Minerals with larger numbers are harder than minerals with smaller numbers and can leave visible scratches on them.
·Minerals with smaller numbers are softer than minerals with larger numbers and cannot leave visible scratches on them.
·The mineral gypsum has a Mohs scale number of 2.
·The mineral apatite has a Mohs scale number of 5.
·The mineral quartz has a Mohs scale number of 7.
The student wants to compare the hardness of gypsum and quartz. Which choice most effectively uses relevant information from the notes to accomplish this goal?
A）The Mohs scale of mineral hardness can be used to order apatite, gypsum, and quartz by their ability to scratch other minerals.
B）A mineral with a Mohs number of 5, like apatite, is harder than one with a Mohs number of 2, like gypsum.
C）Quartz can leave visible scratches on gypsum, which means that quartz is harder than gypsum.
D）Quartz can leave visible scratches on apatite, which is why quartz has a higher number than apatite on the Mohs scale of mineral hardness.
这不是2023年，也不是2024年，也不是OG，这就是今年10月SAT考试的真题，Section 1, module 1的实考真题。
我真的请问了，我们可爱的minerals到底还要在SAT考试出现多少次？我们可爱的Quartz, apatite到底还要出现多少次？出题人是多么喜爱自己小学阶段的自然科学课？他们的课堂里面一定摆满了minerals吧（确信脸）。
如果备考的同学们你没有刷到这骨灰级经典题，可以考虑换个备考方式了。
稍微有点新意的是这个题：
Nanoengineers have developed synthesized cadmium sulfide nanoparticles that are used to provide a heat-resistant pigment for paints. As nanotechnology evolves, paint production ______ to evolve as well.
A） had likely continued
B） will likely continue
C） had likely been continuing
D） would likely have continued
选B。在国际卷直球考时态的题不多，直接选将来时的更是只有两个，这是其中一个。
最后就是考前反复强调预测会考的考点：
During a recent investigation, archaeologists ______ an explanation for the consistent and seemingly deliberate placement of petrogylphs (rock carvings) near water analyzed several sites on Carribbean islands. They discovered that many of the pools near petroglyphs had consistent water levels year-round, creating perfect reflecting surfaces for the carved symbols on the rocks.
A） sought
B） had sought
C） seeking
D） were seeking
选C，果然考了。而且也是老得不能再老了。
语法部分整体上呈现一种只要你刷题了，刷对题目区间了，应该是完美全中状态。
阅读
10月场次整体呈现“难中有旧”的特点，M1旧题重复率明显偏高，尤其是阅读部分的篇章和部分词汇题，不少考生反映遇到了此前亚太或北美场次出现过的原文或相似素材。
推测主要原因有二：一是10月报考人数相对暑期有所回落，题库需求量降低；二是今年下半年考试场次安排较为密集（8月、9月、10月连续出分），CB短期内难以持续输出大量全新题目，因此在难度普通的部分适度复用旧题成为“保稳”策略。
像这道有机碳和水银关系题，题库至少出了8遍。是的你没看错8遍。然后这次是原题重复，一个字没改，可以背答案那种。
Many studies have found a positive association between levels of dissolved organic carbon and mercury in bodies of fresh water undisturbed by human activity. But Mark E. Brigham and colleagues did not find this correlation in an examination of freshwater bodies disturbed by urban development, leading some scientists to hypothesize that the association could be particular to undisturbed waters. However, Tomáš Navrátil and colleagues carried out a study on freshwater bodies disturbed by coal emissions that showed similar results to the studies on undisturbed waters, suggesting that _______
Which choice most logically completes the text?
A） Brigham and colleagues' study used different methods to measure the concentration of mercury in fresh water than Navrátil and colleagues' study did.
B） disturbances linked to urban development affect significantly more bodies of fresh water than disturbances linked to coal pollution do.
C） the effects of urban development on the association between levels of dissolved organic carbon and mercury should not be taken as indicative of the effects of every type of human disturbance.
D） levels of dissolved organic carbon and mercury are both much higher in bodies of fresh water disturbed by urban development than they are in bodies of fresh water disturbed by coal emissions.
像这道“4720”题，上过课的各位应该知道了，4720是著名的trap题—看似文章很长，其实X用没有，答案直接看图就可以比出来。总结过规律的，做题节省5分钟。
While US public charities, like Habitat for Humanity International, must file Form 990 yearly with the IRS, private foundations, such as the David and Lucile Packard Foundation, must file a different form, 990-PF. In addition, foundations that engage in certain prohibited activities must also file Form 4720 and pay a penalty tax on the money involved. Private foundations are prohibited from holding excess interests in a business enterprise, "self-dealing" (conducting activities that benefit foundation insiders), making taxable expenditures such as grants to noncharitable entities, and failing to cross a required threshold in making charitable distributions from income. Out of the organizations that filed Form 990-PF in the years 2003–2005, ______
Which choice most effectively uses data from the graph to complete the assertion?
A） those that filed Form 4720 because they engaged in self-dealing paid an increasing percentage of the total penalty each year from 2003 to 2005.
B） those that filed Form 4720 because they had excess holdings in a business enterprise paid, on average, a larger penalty than those that filed Form 4720 because they made taxable expenditures.
C） those that filed Form 4720 in 2003 because they failed to meet the minimum charitable distribution requirement collectively paid a larger percentage of the total penalty assessed that year than those that filed Form 4720 in 2005 for the same reason.
D）those that filed Form 4720 in 2005 because they engaged in self-dealing collectively paid a larger percentage of the total penalty assessed that year than those that filed Form 990 but also filed Form 4720 for the same reason.
还有这一道关于跨国交通VS国内交通的图表题，这不是9月份刚刚考过？？？那刚考9月再考10月不是发达了？？
A study of commercial airline routes that carried the greatest number of passengers in 2017 and 2018 shows that, in general, domestic routes (routes within a single country) carried many more passengers than international routes. However, a few international routes were so popular that they carried more travelers than some of the most highly traveled domestic routes, as can be seen when comparing the _____
A） distance between Mexico City and Monterrey with the distance between Jakarta and Singapore.
B） number of passengers who traveled between Mumbai and Delhi in 2017 with the number who traveled between Hong Kong and Manila during that same year.
C） number of passengers who traveled between Jakarta and Singapore in 2017 with the number who traveled that same route in 2018.
D） number of passengers who traveled between Jakarta and Singapore in 2018 with the number who traveled between Mexico City and Monterrey during that same year.
难题比例方面，本次考试M2难度题占主导，高难度题分布均匀。阅读部分逻辑补全和双篇关系题仍是最容易拉开差距的板块。
Rare species advantage (RSA) describes the situation in which there are few conspecifics (other members of the same species) in an organism's immediate surroundings, enabling the organism to avoid competition with conspecifics for the same resources; RSA is widely believed to play a crucial role in maintaining ecological stability. Among tree species in the Barro Colorado Island plot (latitude 9.15° N) and other tropical forest sites, there is little correlation between conspecific aggregation and the abundance of a given species in the wider local area, so RSA is expected, but in the Fenglin Nature Reserve (latitude 48.08° N) and other temperate forest sites, the aggregation-abundance correlation for tree species is strongly negative. Mathematical modeling suggests, however, that ecological niche distinction may mitigate the apparent risk to temperate ecological stability engendered by this pattern: _____
Which choice most logically completes the text?
A） even though rare tree species in temperate forests tend to cluster with conspecifics more than rare tree species in tropical forests do, they are sufficiently rare locally that they benefit from RSA more than rare tropical species do.
B） although rare tree species in temperate forests encounter relatively high local competition from conspecifics, they can thrive by exploiting resources that are underexploited by other local species.
C） as a tree species in temperate forests becomes more abundant, individuals of that species are more likely to be found near conspecifics, enabling abundant species to exploit localized resources to a greater extent than rare species can.
D） while an increase in abundance in one tree species often leads to a reduction in abundance of nearby species, temperate tree species tend to play different roles in the same ecosystem, reducing the expected effect of abundance on aggregation.
RSA定义：同种个体少→避免种内竞争→维持生态稳定。
温带森林规律：聚集度和丰度强负相关：物种越常见（丰度高），反而同种聚集越少/物种越稀有反而越扎堆（和热带相反）→ 这意味着温带稀有物种周围全是同种，会面临极强种内竞争，理论上会破坏生态稳定（违背RSA）。
转折后核心：生态位分化（niche distinction，不同物种用不同资源）可以抵消这种风险→ 后面要解释「即使温带稀有物种和同种挤在一起竞争强，靠生态位分化也能活，维持稳定」。
B直接对应：虽然温带稀有树种面临很高的同种局部竞争，但它们可以利用当地其他物种没充分利用的资源（这就是生态位分化的体现），所以可以存活，刚好解释了为什么风险被抵消，完美贴合逻辑。
结论很清晰：押题、猜题、临时抱佛脚的路越来越窄了。以后想在SAT上稳定拿到高分，靠的是长期积累的阅读能力、扎实的语法功底、清晰的逻辑思维，以及稳定的临场心态。这些都不是短期冲刺能补起来的，必须靠日积月累的“绝对实力”。
