再问大全143，非常感谢

1.        As virtually all the nation’s 50 busiest airports are, New York’s were built for an age of propellers, before jet planes weighing 800,000 pounds needed over two miles of runway.

(A) As virtually all the nation’s 50 busiest airports are

(B) As with virtually all of the nation’s 50 busiest airports

(C) Like virtually all of the nation’s 50 busiest airports

(D) Like the cities where virtually all the nation’s 50 busiest airports are（C）

(E) Like other cities where virtually all the nation’s 50 busiest airports are

此题A 单独看一般时are可以，但跟were built时态不匹配， 这点对么？AS 的比较要求时态一一致么？3X

我觉的动词要并行.  Try this:  

As virtually all the nation’s 50 busiest airports were built for a age of propellers, LACE>New YorkLACE>’s were built for an age of propellers, before jet planes weighing 800,000 pounds needed over two miles of runway.>>

GOT IT
