SAT语法主张的是句子的简洁性，那么在语法考察中当然也有自己的侧重点，经过我们的总结，将SAT语法的考点大致划分为以下11中类型。今天的SAT语法改错常见错误小讲堂(二)为大家介绍的是主谓一致原则
1. 句子残缺(不完整句子)
2. 不间断句子
3. 主谓一致
4. 名词，代词的格
5. 代词数的一致
6. 动词时态
7. 比较结构(比较级，最高级)
8. 形容词，副词混用
9. 逻辑主语
10. 平行结构
11. 习惯用语(固定搭配)
在SAT语法改错常见错误小讲堂(一)种，我们介绍了SAT语法的考点中的前两点，现在我们来介绍一下语法改错中要注意的主谓一致原则。
三. Subject-Verb Agreement -主谓一致
1. 在一个句子中，主谓之间不管是人称还是数都应该保持一致，比如动词是单数的形式，那么主语对应的就必须是第三人称，比如说是：
I conjure You lurk She undulates
I am conjuring You are lurking He is ogling
I have conjured You have lurked It has levitated
通常情况下，主谓紧挨在一起的话，我们很容易看出主谓是否一致，但是SAT语法改错中的句子常常会用短语或者是插入语将主语和谓语相隔的很远，因此，考生们就很容易忽略这一点。比如下面的几个例子
A cluster of grapes was hanging just out of the fox’s reach.
The elixir in these bottles is brewed from honey and rue.
The dexterity of her long, thin, elegant fingers has improved immeasurably since she began playing the vielle.
The cabin of clay and wattles was built by William Butler Yeats.
2. 插入语的形式有：
As well as , with , along with, together with, in addition to, no less than, rather than, like等。值得注意的是，插入语的位置虽然会出现在主语和谓语之间，但是并不会影响主谓的一致。比如：
The owl together with the pussycat has gone to sea in a beautiful pea-green boat.
The walrus with the carpenter is eating all the oysters.
Dorothy along with the lion, the scarecrow, the woodman, and her little dog Toto is following the yellow brick road.
Berenice as well as Benedick was hidden under the cloak.
The Trojan horse, including the Greek soldiers hidden within it, was hauled through the gates of Troy.
Henbane, rather than hellebore or rue, is the secret ingredient in this potion.
Henbane, in addition to hops, gives the potion a real kick.
I, like the mandrake, am ready to scream.
同样的道理，如果一个句子当中还嵌套了一个从句，也不能影响主句中主谓一致的原则
The troll who lurched along the corridors was looking for the loo.
The phoenix that arose from the ashes has scattered cinders everywhere.
The way you’re wrestling those alligators is causing them some distress.
3. 但是在复合主语(compound subject)中，谓语动词形式就是复数
The walrus and the carpenter were strolling on the strand.
“The King and I,” said Alice, “are on our way to tea.”
4. 但要注意的是，如果这个复合主语表达的是一件事物，那么即使是有好几个名词构成的主语，谓语动词用的还是单数的形式。
The Lion, the Witch, and the Wardrobe, written by C.S. Lewis, is an admirable tale.
The Eagle and Child is a pub in Oxford where Lewis and Tolkien regularly sampled the admirable ale.
Green eggs and ham was our family’s favorite breakfast every St. Patrick’s Day.
The King and I is a musical comedy.
5. 注意一些艺术，文学作品的名称，标题对应的谓语动词的单复数形式，这些标题通常情况下都是采用单数，但是如果标题中有复数形式，谓语动词的对应形式也还是用单数。
The Burghers of Calais is a statue by Rodin.
下面，我们就来看一个例题进行说明
Example:
Proficiency in (A) mathematics and language skills are(B)
tested in (C) third grade and eighth grade as well as (D) in
high school. No error (E)
这个句子中的主语是Proficiency，所以对应的谓语动词的形式应该是is, 不要被skills迷惑了。
这些就是我们今天介绍的语法当中的主谓一致的用法，希望对正在备考SAT的小伙伴们有帮助。
