PREP48

48. Unlike many United States cities, where a river is no longer the focal point of urban life, the river in San Antonio winds through the middle of the business district, and the River Walk, or Pasco del Rio, is the city's most popular attraction.

A) Unlike many United States cities, where a river is no longer the focal point of urban life, the river in San Antonio

B) Unlike the river in many cities in the United Stated, which is no longer the local point of urban life, in San Antonio the river

C)Today the river in many cities in the United States is no longer the focal point of urban life, unlike San Antonio, where it

D) In few United States cities today, a river is the focal point of urban life, but the river in San Antonio

E) No longer do many cities in United States have a river as the focal point of urban life, but in San Antonio the river

答案是E

No longer...but...不存在对称的问题吗？

B中，which可以指代前面的中心词river啊，in ..in...不是前面的中心词，为什么不对？unlike a, b 的结构比E美观的多

盼

Two fatal errors in B):

1)"local point" distorts the meaning of original sentence

2)"the river in many cities":  single "river" in 'many cities" does not sound logical 

E不存在对称的问题吧...

but做连词跟and差不多用法，and连两个句子的时候我们也不是一定要它非对称不可

B的local应该是typo，我不选B的原因是因为unlike引起的比较不对等

要么是: unlike the river in many cities..., the river in SA....

要么是: unlike in many cities, in SA the river....

请大家拍砖
