—I’ll return the book to Mary but I can’t find her anywhere.—She the teachers’ office. Yo

问题补充：

—I’ll return the book to Mary, but I can’t find her anywhere.

—She the teachers’ office. You can find her there.

A．have gone to B．has gone to C．has been to

答案：

解析：句意:-我会把书还给Mary，但是我到处都找不到她。-她去了老师的办公室。你可以去那里找她。have gone to 去了某地，还没有回来；have been to 去过某地，已经回来了。根据句意可知，Mary现在还没有回来。而且she 是第三人称单数形式，应该用has。故选B。
