##### 考题讲解

A选项：“很少宽于40 feet并且深于12 feet（seldom more than 40 feet wide and 12 feet deep）”和“流经363英里（running 363 miles across the rugged wilderness of upstate New York）”两者均在描述某条河流，所以两者应该平行，本选项中两者一个是词组，另一个是完整句，在语法上不平行。

B选项：Correct. 本选项在语法和逻辑上均是正确的。but身后是一个现在分词短语，做主句的伴随状语

C选项：“很少宽于40 feet并且深于12 feet（seldom more than 40 feet wide and 12 feet deep）”和“流经363英里（running 363 miles across the rugged wilderness of upstate New York）”两者应该是转折关系，因为宽度和深度较差的河流应该无法流的很远，本选项中两者为并列关系，不正确；but身后应该是完整句，不能是一个名词。

D选项：
“很少宽于40 feet并且深于12 feet（seldom more than 40 feet wide and 12 feet deep）”和“流经363英里（running 363 miles across the rugged wilderness of upstate New York）”两者的关系错误同(C)；which connected是定语从句，就近修饰New York，这使得connect的主语为New York，但connect的逻辑主语应该为the Erie Canal。

E选项：
