prep语法(18)

考点: 句子结构（Grammatical Construction） 简洁有效（Rhetorical Construction）

1) 修饰语要尽可能贴近其修饰对象

(A) for centuries修饰语位置不合理,置于has been之间,句子变得不通顺; to become使得句子的逻辑

意思不合理,这里没有目的的意思,应该是表达一个客观事实.

(B) 时态不对,for centuries表示持续的时间,应该用完成时的进行时态; and so becoming没有与之平

行的结构,并列逻辑意思也不对,这里没有因果关系.

(C) 正确, that限定性定语从句修饰fungus; for centuries紧靠修饰对象weaving its way through the

roots of trees符合习惯用法; 用称述语气表达客观事实,符合逻辑意思

(D) for centuries位置不好; 句子结构为Beneath… a fungus that…整个句子没有谓语成分

(E) 整个句子没有谓语成分; to become不符合句子逻辑意思

句子结构: Beneath…, a fungus that… has become…

76. (28643-!-item-!-188;#058&003706)

By recording the noise of crinkled wrappers as they were slowly stretched out in an otherwise silent second long. (A) digitizing and analyzing the sound emissions on computers, a team of scientists found the noise

not

(B) digitizing and analyzing the sound emissions on computers, a team of scientists found that the noise was not (C) digitizing and analyzing the sound emissions on computers, a team of scientists found the noise not to be (D) the sound emissions were digitized and analyzed on computers, a team of scientists found that the noise was not (E) the sound emissions were digitized and analyzed on computers, a team of scientists found the noise not to be

考点: 逻辑表达（Logical Predication） 平行对称（Parallelism）

1) 正式书面语中，动词型宾语从句中的that一般不能省略

2) not…but…连接的对象要平行

3) 一般来说在report, predicate, predict, shown等动词后面之跟简单的名词短语, 若其后面跟的是动

名词或名词所有格+动名词短语(sb’s doing),或名词短语之后用一复杂的现在分词来修饰时,都会造成 句子结构的复杂,笨拙. 经常用that引导宾语从句来对该类句子进行改写

(A) not continuous but consisted结构不平行,continuous是形容词,consisted是动词; 应该用found

that从句来表现found的完整内容

(B) 正确, By recording…, and then digitizing and analyzing结构平行; 使用found that从句更能够清

楚完整的表达found的内容

(C) not to be continuous but consisted结构不平行; 应该用found that从句来表现found的完整内容

(D) By recording… and then the sound emissions were digitized…结构不平行；the sound emissions

作为by recording…的逻辑主语，错误。

(E) not…but..连接对象不平行；the sound emmissions作为by recording…的逻辑主语，错误。

句子结构: By recording…, and then digitizing and analyzing…, a team… found that the noise was
