距离10月1日的新SAT考试还有5天的时间了，小编为大家整理了错误率较高的SAT文法逻辑结构考点，希望对大家的SAT文法考试有所帮助。

　　新SAT语法考试有两大核心考点：

　　1、语言的规范性(Standard English Conventions);

　　2、观点的表达 (Expression of Ideas)。

　　在新SAT语法考试中，语法规范基本上有20道题目，每篇的考试文章大概有5道题;观点表达考点一般有24道题，每篇的考试文章大概有6道题。

　　在新SAT语法考试中，观点表达的派生考点就是逻辑结构题目，具体分为4大类别：

　　1. 句子保留删除题

　　The writer is considering deleting the underlined sentence. Should the sentence be kept or deleted?

　　2. 细节支持题

　　The writer wants to complete the sentence with a third example of a detail Kingman uses to create his majestic city skylines. Which choice best accomplishes this goal?

　　3. 添加段首句题

　　Which choice most effectively establishes the main topic of the paragraph?

　　4. 图表分析题

　　Which choice completes the sentence with accurate data based on the graph?

　　因为图表分析题的难度比较小，所以在此不做赘述。

　　在做新SAT语法考试的逻辑结构题目的时候，小编提醒各位考生一定要记住一个中心和三个基本点去答题，详细攻略如下：

　　一个中心：一个中心指的是紧扣主题，在选择答案的时候要围绕主题句;

　　第一个基本点：如果题号前后信息中有重复的情况，且题干中句子的中心词不是句子前后的重复信息，就一定要选择删除所给句子，减少干扰信息;相反的是，题干中中心词是题号前后的重复信息，那么一定要保留所给句子，因为加上这个句子会改善句子信息流;

　　第二个基本点：添加段首句题目分两种情况：一种是所家句子是第一段句首，一定要紧扣标题中心词;一种是所加句子是body段的首句，要遵循承上启下的原则;

　　第三个基本点：如果是细节支持题，所选择的细节和例子一定要紧扣主题句的中心词，但是此处的主题句未必就是此段的首句，请结合段落内部的结构和层次进行判断。

　　下面小编为大家带来几个例子，希望大家能深入理解：

　　1、句子保留删除题

　　A study conducted in 2013 by Northwestern University in Chicago showed that inadequate natural light could result in eye strain, headaches, and fatigue, as well as interference with the body's circadian rhythms. 3 Circadian rhythms, which are controlled by the body's biological clocks, influence body temperature, hormone release, cycles of sleep and wakefulness, and other bodily functions.

　　3. At this point, the writer is considering adding the following sentence.Workers in offices with windows sleep an average of 46 minutes more per night than workers in offices without windows.Should the writer make this addition here?

　　A. Yes, because it supplies quantitative data that will be examined in the rest of the paragraph.

　　B. Yes, because it explains the nature of the bodily functions referred to in the next sentence.

　　C. No, because it interrupts the discussion of circadian rhythms.

　　D. No, because it does not take into account whether workers were exposed to sunlight outside the office.

　　解析：根据第一个基本点，题号前后的信息中有重复信息：circadian rhythms，并且所给题干中的句子的中心词不是题号前后的重复信息，那么一定要选择删除所给句子，因为加上这个句子会扰乱句子的信息流(interrupt the discussion of circadian rhythms=blur the paragraph's main focus)。所以，答案选C。

　　2、细节支持题

　　Employees who feel less than 100% and are sleep deprived are also less prone to work at their maximal productivity. One company in California 6 gained a huge boost in its employees' morale when it moved from an artificially lit distribution facility to one with natural illumination.

　　6. Which choice best supports the statement made in the previous sentence?

　　A. NO CHANGE

　　B. saw a 5 percent increase in productivity

　　C. saved a great deal on its operational costs

　　D. invested large amounts of time and capital

　　解析：如果是细节支持题，所选择的细节和例子一定要紧扣主题句的中心词，根据题干中的要求，此处的主题句是题号前面的句子，中心词很明显是productivity, 所以，答案选B

　　3、添加段首句题

　　第一种情况：

　　Shed some light on the workplace Studies have shown that employees are happier, healthier, and more productive when they work in an environment 2 in which temperatures are carefully controlled.

　　2. Which choice provides the most appropriate introduction to the passage?

　　A. NO CHANGE

　　B. that affords them adequate amounts of natural light.

　　C. that is thoroughly sealed to prevent energy loss.

　　D. in which they feel comfortable asking managers for special accommodations.

　　解析：根据第二个基本点的第一种情况：如果所加句子是第一段的首句，一定要紧扣标题的中心词：light, workplace。所以，答案选B。

　　第二种情况：

　　His restaurants were immediately successful, but Harvey was not content to follow conventional business practices. 17 Although women did not traditionally work in restaurants in the nineteenth century, Harvey decided to try employing women as wait staff.

　　17. The writer is considering deleting the previous sentence. Should the writer make this change?

　　A. Yes, because it introduces information that is irrelevant at this point in the passage.

　　B. Yes, because it does not logically follow from the previous paragraph.

　　C. No, because it provides a logical introduction to the paragraph.

　　D. No, because it provides a specific example in support of arguments made elsewhere in the passage.

　　解析：根据第二个基本点的第二种情况：如果所加句子是body段的首句，一定要遵循承上启下的原则。His restaurants were immediately successful是承接上文的部分，Harvey was not content to follow conventional business practices是引出下文的部分，这句中的not conventional与第二句话中的not traditionally形成等价的关系。所以，答案选C。

　　以上就是小编为大家分享的新SAT文法逻辑结构考点详细讲解，希望大家能够根据一个中心和三个基本点来选择正确的答案，希望对大家的考试有所帮助。
