1.        Inflation has made many Americans reevaluate their assumptions about the future; they still expect to live better than their parents have, but not so well as they once thought they could.

(A) they still expect to live better than their parents have

(B) they still expect to live better than their parents did

(C) they still expect to live better than their parents had

(D) still expecting to live better than their parents had（B）

(E) still expecting to live better than did their parents

B是最优答案，没问题。但总感觉did既可以指expected也可以指lived，望高手指点！

觉得应该是expected吧，因为是从那开始省略的
