下面為大家整理的是關于SAT寫作滿分需要避免的一些錯誤句式和相應的可以應用的正確句式對比。句式的掌握是大家備考SAT寫作考試中最重要的基礎部分，避免這些錯誤的句式才能對SAT寫作有更多更加靈活的應用。

　　1. 有問題的SAT寫作句式列舉

　　考生在寫SAT寫作的時候，最容易在句式上出現三個問題：一是使用破碎句，二是使用接連句，三是句子連接不正確。

　　1). 破碎句

　　所謂破碎句，就是句子不完整，通常是沒有謂語(或者說謂語是動詞的非謂語形式，如分詞)，或者是從句單獨成句。

　　破碎句：She singing alone. (無謂語，singing是現在分詞)

　　正確句：She is singing alone.

　　破碎句：He did not come. Because he was sick. (從句單獨成句)

　　正確句：He did not come because he was sick.

　　2).接連句

　　所謂接連據，就是兩個句子直接連在一起，既未使用連詞，也未使用正確的標點符號。

　　接連句: Professionals such as lawyers or accountants usually work longer hours than factory workers they have greater freedom in planning their time.

　　正確句一: Professionals such as lawyers or accountants usually work longer hours than factory workers. However, they have greater freedom in planning their time.

　　正確句二: Professionals such as lawyers or accountants usually work longer hours than factory workers; however, they have greater freedom in planning their time.

　　3).句子連接不正確

　　所謂句子連接不正確，就是兩個獨立的句子之間以逗號連接，這是不合英語語法的。正確的做法是以連詞、分號、冒號、句號等連接兩個句子。

　　不正確句: Breaking chalk into two pieces is a physical change, there is no change in the composition of the chalk.

　　正確句： Breaking chalk into two pieces is a physical change, so there is no change in the composition of the chalk.

　　2 高分表達

　　除了在句式上長短句相結合準確表達外，建議SAT考生要使用一些特殊的句式，以使句型多樣化。句型多樣化也是作文得到高分的條件之一。除了我們之前經常提到的高分句式，如倒裝句、強調句、狀語前置、插入語等，另外一個句式的多樣變化，即主語多樣化。下面將列舉幾個句子概括介紹前面四種句型，而重點分析主語多樣化。

　　正常句： Luck only works in extreme cases.

　　倒裝句： Only in extreme cases does luck work.(否定詞位于句首的倒裝。)

　　正常句： The internet provides people access to the latest information.

　　強調句： It is the internet that provides people access to the latest information. (強調the internet)

　　正常句： The environment has been deteriorating severely along with the development of industry.

　　狀語前置句： Along with the accelerating development of industry, the environment has been deteriorating severely.

　　正常句： However, new zoos try to duplicate animals’ natural habitats as much as possible and give animals a comfortable amount of space.

　　插入語： New zoos, however, try to duplicate animals’ natural habitats as much as possible and give animals a comfortable amount of space. (連詞however做插入語)

　　從上面的分析和對比中我們就可以看到，拿到SAT寫作滿分成績需要大家多方面的準備，只有在掌握了最基本的句式，避免基本錯誤的基礎上才能掌握更多的高分表達方式也才能在考試中有更多的發揮空間。
