SAT语法题型的数量一共有三种，包括了对词汇，句子和篇章结构的考察，被归为写作部分中。这三种SAT语法题型的答题方法既有相通之处也有些许的差别。下面大家就和天道小编一起来看看这些答题方法的对比吧，看看对自己有哪些帮助。

　　Improving Sentences Questions

　　These questions test your ability to choose the best variation on a given sentence. In deciding which choice is "best," you should first consider grammar. If an option is ungrammatical, it will never be the correct answer. When you are going through the choices initially, you are on the hunt for any mistakes; this usually narrows your choices significantly and can occasionally lead you to a single correct answer.

　　If choices remain after filtering out the ungrammatical ones, you must next consider the clarity of the sentence. Are all of the pronouns as unambiguous as they can be? Does the sentence flow logically? Are the conjunctions consistent with the intended meaning of the choice? These questions should be running through your mind.

　　If more than one choice remains after applying these techniques, go with the more concise choice. Once ungrammatical choices are eliminated, the correct choice will be the shortest one the vast majority of the time. Keep in mind, however, that the College Board would not consider a choice better simply because it was shorter than another; there is typically an unnecessarily wordy, awkward spot that contributes to the length.

　　Identifying Errors Questions

　　These questions test your ability to recognize usage errors and incorrect grammar. A sentence with four underlined words or phrases will be presented. If one of these four underlined portions contains an error, select it as the answer. If you think that there is more than one error, you have made a mistake. If there is no error, select (E) as the answer.

　　These questions are relatively straightforward and do not require a deep strategy; if you know your grammar (as I hope you do if you have gone through the previous posts), you will do very well. The only strategic thing I do is to mark each question that I think has no error. When I have finished, I return to the marked questions to ensure that there is truly no error. While there is no predetermined number of questions that will have no error, it is good to keep in mind that approximately 20% of the questions will have no error on any given test. But don't let this fact cause you to second-guess answers that you had been confident about.

　　Improving Paragraphs Questions

　　Compared to the rest of the Writing section, these questions have less to do with grammar and more to do with well-organized writing. Diction and clarity also come up.

　　Among other things, you'll be asked to provide better alternatives for sentences and phrases, to fix the syntax of a sentence, and to rearrange sentences within the paragraphs. For the most part, the questions are not as objective or straightforward as the rest of the Writing section, so your best preparation will be to work through the Improving Paragraphs questions from The Blue Book. Once you get a hang of these, however, they can become quite easy.

　　通过以上三种SAT语法题型答题方法的对比，大家可以看到，在备考SAT语法考试的时候，理解并熟练应用相关知识点是最重要的基础工作，对于相应的答题方法则在于大家备考中根据个人的特点结合题目的特点进行应用。
