法则四：文章由始至终的使用简单的语句。

在你的写作的时候，尽量的使用简单的词汇并写作易懂的语句。这样做，可以使读者更清楚的明白你的立场和你文章的目的。要记住，SAT写作不是考察你的生词量，而是在考察你是否能将你的想法通过文字的方式传递给读者。

如果想做到这点，那么作者在写作的时候，应该避免使用那些无关紧要的词汇，模糊不清的词汇，和条例不清的语句。让我们来看下面的例子；

例 To facilitate input by the maximum number of potential purchasers, questionnaires were designed and posted well in advance of the launch of the promotional marketing campaign.

Improved: Before we began advertising, we designed and mailed a marketing survey to find out what customers were looking for.

通过比较，我们可以清楚的明白，上面的句子，使用了一些不必要的词汇，而导致句子看上去繁琐难懂。下面的句子，经过编改，变得简单易懂。

法则五：避免使用俚语。

SAT的写作考试，要求的是一篇有专业性的写作，而不是一篇日记或随笔。所以使用俚语不应该在SAT的考试中出现。例如，在高考的时候，考生把“我要去…”写成“俺要去…”加有地方方言的语言方式。

下面让我们通过英文的例子来说明；

例1 Brian’s mother reprimanded him for blowing his physic test.

Improved: Brian’s mother reprimanded him for failing his physic test.

同样的，考生在写作的时候，也应该尽量避免太多学术性强的语言。批卷的老师很有可能并不想你一样是个电脑高手。他或她可能只明白一些初级的电脑词汇，对于那些技术性强的词汇，可以一窍不通。 下面让我们通过英文的例子来说明；

例2 Close-support, transport, and reconnaissance assistance is provided by the S-3X helicopter, which is the most cost effective in a crane configuration.

Improved: The S-3X helicopter provides support, transportation, and reconnaissance. However, the helicopter is most cost effective when it works as a crane.

法则六：合并短句,截断长句

1.合并短句可以让你的文章更连贯，读者阅读的时候思路也会更清晰。让我们通过下面的举例来学习如何合并短句。

例1 The glee club held a fund-raiser, the basketball team also held a fundraiser.

Improved sentences: The glee club and the basketball team held fundraisers (compound subject)

例2 Kareem opened the door, He invited all of us in.

Improved sentences: Kareem opened the door and invited all of us in. (compound verb)

例3 The most valuable player on the basketball team will give the graduation speech. She is the star of this year’s musical.

Improved sentences: The most valuable player on the basketball team, who is also the star of this year’s musical, will give the graduation speech (appositive)

例4 The wide receiver ran down the field. He caught the winning touchdown pass

Improved sentences: Running down the field, the wide receiver caught the winning pass (modifying phrase)

例5 The writer wanted to finish his reading. He did not want to be interrupted with questions

Improved sentences: The writer did not want to be interrupted with questions before he finished his reading. (Complex sentence)
