　　阅读

　　SAT/ACT/SSAT阅读教研组长 田野老师

　　3月机考SAT阅读部分整体难度中等，和Bluebook的题目很接近，建议考前把真题完全吃透。

　　而且词汇一直是阅读部分的考察重点，为了更好地应对考试，建议词汇量积累10000-12000。同时，注重机考Bluebook和真题机经词汇的积累。

　　对于SAT考生来说，阅读部分相对而言信息量很大，选项也比较长，对于时间的把控至关重要，建议考前坚持模考，把握做题速度。

　　此外，考试的题目和Bluebook中题目的考点完全相同，所以把握不同考题的考点至关重要。能够熟练掌握不同题型的重点和解题方法，可以有效提升分数。

　　本次SAT阅读部分题目回忆如下(内容根据参加考试的教师和学生回忆进行整理，仅供参考，具体考试内容可能和本版本有细微差异)：

　　Details 细节题

　　1.In Oodham, an Indigenous language from the Southwest region of what is now the United States, gogs means "a dog", whereas gogogs is used to refer to several dogs. This phenomenon, in which an element of a root word is repeated, sometimes with modification, within another word that is related to the root word, is called reduplication. In this case, the element "go" in gogs gets repeated in gogogs. There are many examples of this type of reduplication in O'odham.

　　The text makes which point about the O'odham word gogogs?

　　A) It contains a repetition of the element "go" in gogs.

　　B) It doesn't have a clear equivalent in English.

　　C) It is the only word in O'odham that uses reduplication.

　　D) It is identical in meaning to several other words in O'odham.

　　参考答案 A

　　2.Researchers César A. Hidalgo, Elisa Castañer, and Andres Sevtsuk created a computer model to predict the mix of gyms, beauty salons, and other businesses found in a given neighborhood. How we define a neighborhood and its boundaries is subjective, so the team used a clustering algorithm to locate dense groupings of amenities that represent human- identified neighborhoods like Boston's Central Square. The predictive model, which incorporates this algorithm, is sure to be invaluable in determining the optimal mix of a city's amenities.

　　According to the text, why did the team employ a clustering algorithm?

　　A. The algorithm provided insight into how customers are made aware of new gyms and beauty salons.

　　B. The algorithm gave them an objective way to identify neighborhoods.

　　C. The algorithm could be used to evaluate the reasons for a business's closing.

　　D. The algorithm could predict which types of businesses would be successful in a given neighborhood.

　　参考答案 B

　　Command of evidence: textual 文本证据题

　　Some fuel additives contain cerium oxide nanoparticles (Ce02-NPs), which can leach into waterways and soils via wastewater. In a 2015 study, Maël Garaud and colleagues found that CeO2-NPs can accumulate in the bodies of zebra mussels (Dreissena polymorpha). While bioaccumulation of manufactured nanoparticles may be inherently worrisome, it has been hypothesized that CeO2-NP bioaccumulation in invertebrate like D. polymorpha could serve a valuable proxy role, observing the need for manufacturers to conduct costly and intrusive sampling of vertebrate species- such as rainbow trout (Oncorhynchus mykiss), commonly used in regulatory compliance testing for manipulative bioaccumulation, as environmental protection laws currently require.

　　Which finding, if true, would most directly weaken the hypothesis presented in the text?

　　A. When D.polymorpha and O. mykiss are exposed to similar levels of Ce0z-NPs, concentrations of CeO2-NPs in animals of both species show little variation from individual to individual.

　　B. The rate of CeO2-NP uptake in D. polymorpha differs from the rate of CeO2-NP uptake in O. mykiss in a way that is not yet well understood by researchers.

　　C. D. polymorphahas been shown to accumulate several other types of manufactured nanoparticles in addition to CeO2-NPs, whereas O. mykiss has been shown to accumulate only Ce02-NPs.

　　D. Compared with O. mykiss, D. polymorpha can accumulate detectable CeO2-NP concentrations with significantly fewer negative effects.

　　参考答案 B

　　Inferences 推断题

　　In the early 19th, ships in the British Royal Navy were ranked based on military strength. The system considered the number of a ship's cannons and decks. “First rate” was the highest ranking, and “sixth-rate” was the lowest ranking, followed by unranked ships. This ranking determined the size of a ship’s crew: first-rate ships had between 850 and 875 crewmen, while lower- ranked ships had fewer. Two of the ships in the British Royal Navy from this period were the Dreadnought (98 cannons and three decks) and the Royal George (120 cannons and three decks). Of these two, only the Royal George was ranked a first-rate ship. It can therefore be concluded that __________________

　　Which choice most logically competes the text?

　　A) the Dreadnought had between 850 and 875 crewmen.

　　B) all ships with at least 98 cannons were ranked as first-rate ships.

　　C) the Royal George needed a crew larger than 875 people in order to operate efficiently.

　　D) not all ships with three decks were ranked as first-rate ships.

　　参考答案 D

　　文法

　　优秀教师 刘佳烁老师

　　3月SAT文法部分可谓是非常友好。自去年开始，SAT文法部分的考试无一例外包含了我们平时所学的全部知识点(如主谓一致、逻辑主语、标点符号、划分句子结构等)。

　　阅读和文法之间的题量分布完全符合官方给出的这个标准：

　　但每位同学的题目分配细节会有不同，比如有加拿大地区的考生反馈“语法我的sentence boundaries, 好像只有3道题，感觉transition题比较多，并且transition有一道很难。”

　　平时准备充分以及基础比较扎实的同学普遍反馈说Module one比较容易，即使Module two进入到了hard模式也会比较有信心的去应对，更有同学会选择先完成文法的部分。整场考试完毕后，同学们也都会认为文法部分最有把握，全部的知识点均在课堂上被覆盖。

　　备考建议：第一步，系统地学习每一块语法module;第二部，进行大量的专项练习;第三步，利用套题进行反复训练、模拟以及反思。

　　从本次考试内容上来看，知识点考察灵活度增加的部分为：一元二次函数的多种形式和应用、一元二次函数解的数量、圆的方程和分析应用、三角函数的公式转换、统计度量、不等式的范围计算、以及相似图形的对应比例关系等，这些也都是着重考察的部分，且灵活度有明显的提升。

　　尤其是module2中有几道题干篇幅较长的题目，要求考生准确的定位数据信息，并且完成快速运算。所以考生需要注意在平时学习或做题过程中多加训练自己应用题数据获取和数据构建关系的能力。

　　从整体来看，考察的内容和难度都在考纲的要求范围之内，也算是中规中矩，只是灵活度有所增加。建议同学们多进行计时刷题训练，整理错题和分析，多多复盘举一反三，考前建立良好的考试心态，考试的过程中一如往常的稳定发挥，仔细审题避免马虎，计算灵活多加检查，数学部分会给予你很好的分数回馈。

　　以上就是3月北美地区机考SAT的考情回顾啦，希望参加本次考试的同学们都能够取得理想的成绩!
