  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2

  3. 用法

  (1) 表原因用because最简洁, because和why等因果词,在一句内不重复。

  例句1: The reason why he left college was that his health became impaired.

  例句2: He left college because his health became impaired.

  解析:例句1和2表示内容一致,但例句1中有reason, why语义重复,而例句2的because表示最简洁。

  例句3: The only reason why she did not divorce him after his affair was because of their daughter.

  例句4: She did not divorce him after his affair only because of their daughter.

  解析:例句1和2表示内容一致,但例句1中有reason, why和because of语义重复,而例句2的because of表示最简洁。

  (2) 插入语中who be, which be不选。

  例句1: His brother, who had been a member of the same firm for three years, quit last year.

  例句2: His brother, a member of the same firm for three years, quit last year.

  解析:例句1和2表示内容一致,但例句1中有用了who had been从句的形式,而例句2用了a member of短语的形式,故例句2更简洁。

  (3) 含有being, having不选。

  例句1: Being a Sunday, I didn’t get up until 10am.

  例句2: I didn’t get up until 10am because it was Sunday.

  解析:例句1和2表示内容一致,都表示由于周天10点才起床,但例句1没有明确因果关系,例句2用because明确因果关系,故例句2更优先。

  例句3: Our work having been done, we left school early.

  例句4: We left school early because our work had been done.

  解析:例句1和2表示内容一致,都表示我们早离校是因为我们已经完成了任务,但例句1没有明确因果关系,例句2用because明确因果关系,故例句2更优先。
