掌握SAT语法考试的知识点对于大家更快更好的解答SAT语法考试题目有非常大的影响，下面为大家整理了英文版的SAT语法考试的常见知识点，非常详细，供大家在备考的时候，进行适当的参考和借鉴之用。

1.Sentence structure problem

1) Independent clauses (clauses that can be sentences themselves)

Can be joined with comma + conjunction, or semicolon

Comma splice problem: independent clauses joined with ONLY a comma are wrong

Run-on sentence problem: independent clauses joined with nothing, wrong

2) Subordinate/dependent clauses (clauses that needs to latch onto an independent clause, e.g. “Sam is very dirty and needs a bath” – independence clause = Sam is very dirty, dependent clause = needs a bath, conjunction = and)

- often at the beginning/end of a sentence

- test for independent clauses: remove dependent clause, still makes sense

- Sentence fragment problem: several dependent clauses w/ no independent clause

2.Verb problem

1) all verbs should have the same form (to eat/to run, became/attended)

- Nouns describing a group of people (audience, family, USA) are singular

- Either, neither, none, each, anyone, no one, everyone are all singular

- Subjects joined by and are plural (X and Y are)

- Nouns joined by or can be either singular or plural, depending on the last noun given (Jane or John is, Jane or the girls are)

2) proper tense

- Verb tense does not change within a sentence (“In colonial times…did not…knew)

3.Noun problem

1) Subject-verb agreement

4.Pronoun problem (pronoun = word used to rep. a noun, e.g. ‘he’, ‘she’, ‘it’)

1) Agreement

- Everyone must hand in their homework is wrong, since ‘everyone’ is singular

2) Ambiguity

- It should be very clear which noun the pronoun is replacing – “Mary agreed with Martha that her porch” is incorrect since it is not clear whether her is Mary or Martha

3) Usage of right case (subjective/objective)

- Subjective pronoun does something, objective pronoun has things done to it

- I did it – ‘I’ is subjective (doing something), it happened to me – “me” is objective

- Subject pronouns: I/we, you/you, he/they, she/they, it/they, who/who

- Object pronouns: me/us, you/you, him/them, her/them, it/them, whom/whom

- The book belongs to ME, Claire is more creative than I (am).

5.Preposition problem (about, above, across, around, along – used to add info to a sentence)

1) Using different prepositions can change the meaning of a sentence
