【正确答案】 B

【答案解析】此题属于词语搭配题。as far as...be concerned表示“就…而言”，例如：As far as I am concerned，I cannot object to your decision．此题属固定搭配，故选项[B]concerned正确。选项[A]talked(谈论)，不符合题意;选项[C]mentioned(提到)，例如：He casually mentioned that he was leaving his job．选项[D]involved表示“涉及，卷入，牵涉”，常与in/with搭配，例如：(1)The four men were all involved in organizing and carrying out the murders．(2)Winning the game involves both skill and fortune．(想赢这场比赛，既要技巧也要运气。)
