3（）
A.exotic
B.temporary
C.dim
D.few
参考答案：C
解析：
题句…and last but not least the ability to expect the best even if the chances are______前后是转折让步关系，据此可以推断，空白处要填人的词需含有否定含义。[C]dim意为“暗淡的，模糊的”，常用来修饰chances一词(复数形式意思是可能性)，表示可能性很小，如：His chances of survival are dim.“他生还的可能性不大。”[A]exotic意为“外来的，异国的”；[B]temporary“暂时的，临时的”；这两项用在句中明显不合逻辑，[D]few“少”，谈到机会时我们用多或少来形容，而该句中的chances不是指机会，所以也是错的。
