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
我试着解释一下 原句的逻辑意思是system is the Incan highway,逻辑意思不对the Incan highway可以是系统,但不能说系统是Incan highway。所以B错。纠正这个错误的一个方法就是把is去掉,用逗号连接,那The greatest road system built in the Americas prior to the arrival of Christopher Columbus 就可以做the Incan highway的同位语。主语是the Incan highway,谓语是was,而 extending作主句的伴随状语,说明2500米长到什么程度,from northern Ecuador through Peru to Southern Chile.
