对于SAT语法来说,想要SAT语法提分,一定要了解sat语法知识点,这对备考是很有帮助的。一起看看新航道SAT小编给大家整理的SAT备考干货：SAT文法知识点（二十一）内容吧。

　　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。

　　B. a glimpse of optimism was offered by Treasure Island and its accompanying
　　C. Treasure Island and its accompanying was offering a glimpse of optimism
　　D. Treasure Island and its accompanying was offered by a glimpse of optimism
　　解析：通过长短选项看出是简洁的考点，根据“主动优先于被动”的原则，排除含有was offered by被动内容的B和D项；又根据句意判断为一般过去时，所以排除含有was offering过去进行时的C项，所以选A。
