B. satisfied, satisfied
C. satisfying, satisfied
D. satisfying, satisfying
答案：
A. satisfied, satisfying
(答案→)B. satisfied, satisfied
C. satisfying, satisfied
D. satisfying, satisfying
解析：考查形容词用法。Be satisfied with…对…满意；形容词satisfied修饰名词微笑，通常过去分词转换的形容词修饰人，现在分词转换的形容词修饰事物。但smile是与人有关的，使用和look一样也用satisfied修饰，故B正确。
