The greatest road system built in the Americas prior to the arrival of Christopher Columbus was the Incan highway, which, over 2,500 miles long and extending from northern Ecuador through Peru to southern Chile.
A. Columbus was the Incan highway, which, over 2,500 miles long and extending
B. Columbus was the Incan highway, over 2,500 miles in length, and extended
C. Columbus, the Incan highway, which was over 2,500 miles in length and extended
D. Columbus, the Incan highway, being over 2,500 miles in length, was extended
E. Columbus, the Incan highway was over 2,500 miles long, extending
选择E,B里面, over 2,500 miles in length, 这样的一个插入语之后,就变成The greatest road system built in the Americas prior to the arrival of Christopher Columbus was the Incan highway and extended.. 这里的and没办法平行,因为前半句谓语是was,后半句平行的话谓语也应该是was而且需要省略。
B. Columbus was the Incan highway, over 2,500 miles in length, and extended
extend(v) 對應到的S是 The greatest road system,中間插入句不看就變成:
The greatest road system extended rom northern Ecuador through Peru to southern Chile
這樣會變成系統縱貫from northern to southern 句意就不通啦
E. Columbus, the Incan highway was over 2,500 miles long, extending 還原為原句為: The Incan highway was over 2,500 miles long and extended from N to S 高速公路縱貫from northern to southern 句意就通了~
