My father, together with some of his old friends, （）    there already.

题目解析 题目：My father, together with some of his old friends, （） there already. A.will be B.had been C.has been D.have been 答案:C 解析：这道题考查主谓一致和时态。句子的主语是"My father, together with some of his old friends"，这是一个复合主语，其中"My father"是主语，"together with some of his old friends"是介词短语，不影响主谓一致。主语是第三人称单数，所以谓语动词应使用单数形式。另外，题干中已经提到"already"，暗示了动作已经发生，因此需要使用现在完成时。正确答案是"has been"。
