GMAT语法问题求解

(C) should test scores showing their students' mastery of reading skills has
(D) if test scores showing their students' mastery of reading skills having
(E) if test scores show that their students' mastery of reading skills has
by which 中 by怎么理解
为什么用has
正确答案选E
1 从语法角度说，Seldom more than 40 feet wide and 12 feet deep , but it ran 363 miles across the rugged wilderness - - - 里面的but 应该去掉，因为seldom (being) more than 40 feet wide and 12 feet deep 是分词结构部分。分词结构部分属于句子的一部分，是状语成分，不需要连接词参与。总感觉，原句有语法问题。
或者，整个句子可以这样改写：Seldom （being）more than 40 feet wide and 12 feet deep , but running 363 miles across the rugged wilderness of upstate New York, the Eric Chnal connected / connects the Hudson River .......
being 与 running是并列的分词结构部分，用but连接。connected / connects是句子的谓语动词。这样，句子就平衡了。
2 that == the coastal flooding
by是通过的意思,这句理解应该为
individual teachers would be given raises or bonuses by a system 教师将被通过一个系统进行评价和发奖金
by which引导的从句是说明system的
因为是mastery of reading skills ,阅读技巧的熟练程度,是不可数的,所以用has
