问题描述：
Where is he?—He ______ to the teacher’s office.And he ______ there for two hours
填 has been to 还是 has gone to 为什么
答
第一个has gone to （已经去了）
第二个has been to
答
第一个是has gone to因为他去了还未回。第二空是has been to是表示持续
答
have gone to ,have be
第一空 have gone to 失去了某地人未回,have gone to 是去过某地人已回
第2空have been in sp. for +一段时间,又因为是there,省略in
答
Where is he? —He ___has gone to ___ to the teacher’s office. And he ___has been to ___ there for two hours
has gone to 是去了还没回来。。。has been to 是去了已经回来了或表一个状态
