SAT备考知识点推荐： SAT文法知识点第21期

一、简洁

1.含义：

语法规则表达准确，并且句子结构表达简洁。

2.类型：

(1)简洁题 - 有效的书写规则1

3. 用法

(1) 主动 > 被动(主动优先于被动，“>”表示优先于，下同)

例句1: I shall always remember my first visit to Boston.

例句2: My first visit to Boston will always be remembered by me.

解析：例句1是主动语态而例句2是被动语态，主动语态通常比被动语态更直接(direct)，更有力(powerful)，故例句1更优先。

(2)直接动词 > there be 结构

例句1: There were a great number of dead leaves lying on the ground.

例句2：Dead leaves covered the ground.

解析：例句1和例句2表达意思相同，但例句2表达更直接(direct)，更为简洁，故例句2更优先。

(3)V. > Be

例句1: It was not long before he was very sorry that he had said what he had.

例句2: He soon repented his words.

解析：例句1和2表述内容一致，但例句2的repent比例句1的was更简洁。
