本文将介绍一些常见的SAT语法练习题，并提供一些解题技巧。

一、主谓一致主谓一致是英语语法中的基本原则之一。

在SAT语法部分的练习题中，经常会涉及到主谓一致的考察。

例如，下面这道题目：1. Neither the students nor the teacher ________ able to solve the math problem.A. isB. areC. wereD. was解析：在这道题目中，主语是“neither the students nor the teacher”，由于主语是复数形式，因此动词应该使用复数形式。

二、代词的使用代词在英语语法中起到指代作用，正确的使用代词可以使句子更加简洁明了。

下面是一个关于代词使用的练习题：2. Each of the students in the class has ________ own laptop.A. theyB. theirC. his or herD. its解析：在这道题目中，代词应该与前面的名词“each”保持一致。

三、冠词的使用冠词在英语语法中用于限定名词的范围，正确的使用冠词可以使句子更加准确。

下面是一个关于冠词使用的练习题：3. I saw ________ eagle flying in the sky.A. aB. anC. theD. no article解析：在这道题目中，名词“eagle”以元音音素开头，因此应该使用不定冠词“an”。

正确答案是B选项。

SAT语法改进句子题讲解

SAT语法改进句子题讲解任何考试都是技巧和实力的结合，但SAT相对来说，还是更能考察一个学生的综合实力。

如果说SAT考试还有那么一点点可怜的技巧的话，那么，这个技巧部分最明显的体现就是在语法部分。

这一部分可以说中国学生的强项，也是可以通过技巧迅速提高的一块。

但比较麻烦的是，这一部分的扣分标准相当的严格。

经常能见到有的学生在即将考试的关头找到老张，每每此时，老张都紧皱眉头，但出于革命人道主义精神，老张总是无可奈何的说：帮你把语法那一块整一整吧。

因为老张清楚，这也是唯一一块还可以临时报抱佛脚的部分。

顺便提醒各位同学，SAT真的不是靠技巧三下五除二就可以解决的，要想拿高分，还是应及早未雨绸缪，免得到时候手忙脚乱，揪心纠结的。

语法部分和作文的最后得分合并，就构成了SAT写作部分的最后得分（满分是800分）。

根据2010年1月份的真题扣分标准来看，如果一个考生的作文时9 分的话，如果49道语法题一题不错，则最后得分是800分；如果错了一道语法题，则最后得分是780；如果错两道试题，则最后得分是750；如果错了三道语法题就比较麻烦了，加上倒扣的一分原始分，最后得分是710。

就是说，在接近800分的位置，你每错一题，大概要扣掉30分。

可以这么说，如果你的作文是9分（世界平均分大约是7.5分），而你的语法又错了3题甚至以上，那么这次考试的最后分数想上2300大概就要成问题了。

如此看来，SAT的语法虽然简单，但是由于苛刻的扣分标准，说简单也不是那么简单了。

在SAT的每次真题中，改进句子的试题共25道，占49道文法试题一半以上。

改进句子的考试形式是这样的：在一个句子中，有部分甚至全部都被划线，然后提供ABCDE共5个选项，要求考生从中选出一个最完美的选项。

其中A选项和原句的划线部分一样，如果考生认为原句划线部分表达没有问题就选A，如果认为A 不够完美，就从BCDE中寻找正确答案。

例：Lanura Ingalls Wilder published her first book and she was sixty-five years old then.(A) and she was sixty-five years old then(B) when she was sixty-five years old then(C) at age sixty-five years old(D) upon the reaching of sixty-five years old then(E) at the time whenshe was sixty-five years old上面的例题是个标准的改进句子试题，其中A选项为原句划线部分。

SAT语法句子改进题介绍

SAT语法句子改进题介绍本文为大家整理的是关于SAT改进句子常考语法点的相关分析和介绍，非常实用。

大家在备考自己的SAT语法考试，尤其是最基本的改进句子题型的时候，对于语法点的应用是最基础的也是对成绩影响最大的，来看看详细的内容介绍吧。

SAT语法句子改进题是一种新题型，这种新的题型一般以一个长句作为一个最小单位，句子或句子的部分画线，针对画线部分给出了五个选项，其中选项A是原画线部分，BCDE 对A做了修改，要求考生在五个选项中选出最正确和最简洁的。

句子改进题的特点是：正确性，简洁性，最佳性。

SAT语法句子改进题的常考语法体系：1、主谓一致。

尤其用于倒装时，比如therebe句型或地点状语至于句首，要找到真正的主语；有插入语时，要勇敢的抛弃非中心部分，找到真正的主语;主谓一致还会出现在一些固定用法中，但是一般比较简单，比如neither nor或者not only but also等等。

2、逻辑主语，当分词或者形容词放在句首，一定要考虑它的主语问题。

3、时态的混用，常出的错误是：have+过去式，过去完成时和一般过去式混用，现在完成时和一般过去式的混用。

4、名词和代词，常常名词单复数混淆，男女混淆，主格宾格混淆；也会在their、it 和they之间指代不明；关于指代，跨段之间不能指代，it不能指代整个句子，只能指代一个名词或动作，one和they不能相互指代，one和you也不能相互指代；this不能单独充当主语和宾语。

5、同类比较，只有同类的东西才能用于as well as和than句型。

EG：The population of China is larger than that of America.6、adj和adv的混用：adj修饰名词，adv可以修饰除名词外的大部分词。

Adj和adv 两者之间用比较级，三者或三者以上用最高级。

7、句子结构上，“，”不能连接两个句子，“；”等于and，必须连接两个句子；且一个长句中，谓语动词和连接词的数目要平衡。

SAT语法句子改错题解析

SAT语法句子改错题解析SAT语法句子改错题规则有时和我们通常所学的语法书上的知识点有所出入，规则也不尽相同。

再次，SAT语法句子改错题的考察中，不仅仅会考到你是否能判断这个句子正确与否，而且会考到这个句子是否有效和简洁，这就大大提升了题目的难度。

下面小编整理的就是关于SAT语法句子改错题解析的相关内容，大家请看下面5个题：1. A patient accusing a doctor of malpractice will find it difficult to prove damage if there is a lack of some other doctor to testify about proper medical procedures.(A) if there is a lack of some other doctor to testify(B) unless there will be another doctor to testify(C) without another doctor's testimony(D) should there be no testimony from some other doctor(E) lacking another doctor to testify2. Samuel Sewall viewed marriage, as other seventeenth-century colonists, likea property arrangement rather than an emotional bond based on romantic love.(A) Samuel Sewall viewed marriage, as other seventeenth-century colonists, like a property arrangement rather than(B) As did other seventeenth-century colonists, Samuel Sewall viewed marriage to be a propertyarrangement rather than viewing it as(C) Samuel Sewall viewed marriage to be a property arrangement, like other seventeenth-centurycolonists, rather than viewing it as(D) Marriage to Samuel Sewall, like other seventeenth-century colonists, was viewed as a property arrangement rather than(E) Samuel Sewall, like other seventeenth-century colonists, viewed marriage as a property arrangement rather than3. Under the Safe Drinking Water Act, the Environmental Protection Agency is required either to approve individual state plans for controlling the discharge of wastes into underground water or that they enforce their own plan for states without adequate regulations.(A) that they enforce their(B) for enforcing their(C) they should enforce their(D) it should enforce its(E) to enforce its4. Last year, land values in most parts of the pinelands rose almost so fast. and in some parts even faster than what they did outside the pinelands.(A) so fast, and in some parts even faster than what they did(B) so fast, and in some parts even faster than, those(C) as fast, and in some parts even faster than, those(D) as fast as, and in some parts even faster than, those(E) as fast as, and in some parts even faster than what they did5. In the mid-1960's a newly installed radar warning system mistook the rising of the moon as a massive missile attack by the Soviets.(A) rising of the moon as a massive missile attack by the Soviets(B) rising of the moon for a massive Soviet missile attack(C) moon rising to a massive missile attack by the Soviets(D) moon as it was rising for a massive Soviet missile attack(E) rise of the moon as a massive Soviet missile attackAnswer to Question 1Only C, the best choice, manages to convey the meaning of the sentence efficiently and idiomatically. Choices A and D are plagued by awkwardness and wordiness. Choice A also introduces the unidiomatic phrase lack of some other doctor. Choice B incorrectly uses a future-tense verb (will be) in the if clause; the if clause must use the present tense if it is preceded, as here, by a result clause that uses a future-tense verb (e.g., will find). Choice E introduces a dangling modifier: the lacking ... phrase cannot logically modify damage, the nearest noun.Answer to Question 2In E, the best choice, a modifying phrase begun by like immediately follows the name it modifies, Samuel Sewall. E also uses the idiomatic construction viewed marriage as.... Choice A inserts an adverbial modifier, as other... colonists, without the necessary did. It also uses the unidiomatic construction viewed marriage like .... Both B and C use the unidiomatic construction viewed marriage to be ....C incorrectly places the adjective phrase like other... colonists after the word arrangement, which it cannot logically modify.D offers a confusing and awkward passive construction marriage to. Samuel Sewall... was viewed....Answer to Question 3E, the best choice, is the only one that maintains grammatical parallelism by using an infinitive--to enforce—to complete the construction either to approve ... or.... All of the other choices offer syntactic structures that are not parallel to the infinitive phrase to approve. In addition, choices A, B, and C use plural pronouns (they and their) that have no grammatical referents.Answer to Question 4The properly completed sentence here must (1) use the proper form of the comparative conjunction, as fast as; (2) enclose the parenthetical statement and... even faster than in commas; and (3) preserve parallel structure, clarity of reference, and economy by using those to substitute for land values in the completed comparison. D, the best choice, does all these things correctly. A and B use so unidiomatically in place of as. A and E omit the comma needed after than and use the confusing and unparallel what they did instead of those. C omits the second as needed in the comparative conjunction as fast as.Answer to Question 5Choice B is best because it alone correctly handles the idiom to mistake x for y. Though choice D manages the correct preposition, for, the phrase the moon as it was rising for is less efficient and precise than the phrasing of choice B: since rising functions as a verb in D, the phrase for a massive... attack now seems to modify rising rather than mistook. Choice C incorrectly uses mistook... to, and choices A and E incorrectly use mistake ... as. Choice E also employs the nonidiomatic rise of the moon.以上就是小编整理的关于SAT语法句子改错题解析的相关内容，很多情况下SAT语法句子改错题不是让你选择一个完全正确的答案，而是让你选择一个最佳答案。
