She was always , even when things were at their worst.

A. attractive

B. optimistic

C. pessimistic

D. frightened

答案：

A. attractive

(答案→)B. optimistic

C. pessimistic

D. frightened

解析：句意:她总是很乐观，即使当事情非常糟糕的时候。attractive 吸引人的； optimistic 乐观的；pessimistic悲观的；frightened 害怕的。根据even（即使），表示让步关系，又worst.最糟糕的，可知她在糟糕的时候表现的不差，叫乐观。故选 B。
