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 Paseo del Rio, is the city's most popular attraction.

(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 the United States have a river as the focal point of urban life, but in San Antonio the river

答案:E...句子中的强烈语气必须保持是对的...但是B哪里错了么?是which指代的不对么?请NN指教

B选项，which前面有三个名词，river，cities，US， 哪一个都可以和  is no longer the focal point of urban life 搭配。

        所以不能从意思上 宽容WHICH的跳跃指代问题，   而且后面 应该接 RIVER IN SAN ANTONIO 才够对称
