(A) Rivers originally flowed into the St.Lawrence by way of Lake Michigan, but havingbeen
redirected by constructing
(B) Rivers had originally flowed into theSt. Lawrence by way of Lake Michigan, but theyhave been
redirected by constructing

(D) Rivers, originally flowing into theSt. Lawrence by way of Lake Michigan, buthaving been
redirected by the construction of
(E) Rivers, originally flowing into theSt. Lawrence by way of Lake Michigan, havebeen redirected
through the construction of
句子结构：… Rivers,flowing…, have been redirected through… so that …
主语是rivers，由现在分词结构flowing…作定语修饰，谓语是have been redirected。
1) 句子结构，在主从复杂句子中要注意主句和从句的主谓结构是否齐全，常见的错误选项是缺少主
2) 有效用词，by doing与by+noun. 在语法上都正确，但前者强调动作，后者强调结果，在GMAT语
法中，通常是by+noun.是正确表达方式。 关于这点的解释我真的很无奈，昨天刚刚看到“because，by doing用法优先，我还记了下来，背过了，放在这里怎么又成了by+n.是正确的表达了。我这个汗啊！！！
还有，我们不都一直说忠于原文么，原文的逻辑意思不要改变，所以这题我很自然就想啦，原文是个转折意，那么选项也应该是，结果错了！

这个我更无语了，我是上来就把带these的给排了，虽然我觉得they在这里也不是那么好，可是these错的太不能原谅了啊，不能做主语啊！！现在给出的解释又是these指代前面，可是我明明记得以前的题里面，these也都是有指代前面的某个词的，可是不管怎么样它都不能单独做主语啊！！！
