My dad Singapore for a meeting. He there twice.
A. has gone to, has been to
B. has been to, has gone to
C. has gone to, has been
D. has been to, has gone

A. has gone to, has been to B. has been to, has gone to(答案→)C. has gone to, has been D. has been to, has gone解析：句意：我的爸爸去新加坡开会了。他已经去过那儿两次了。结合语境可知前文强调的是现在已经完成的动作，故用瞬间动词。下文描述的是到现在已经完成的过去某种状态，there在本句中是地点副词，前面不要介词，故选C。
