2.—Excuse me, where is Room 301?

—Just a minute. I’ll get Bob ____ you to your room.

A.to show B.showing

have sb doing sth （e.g. He found it quite natural to have people fussing over him.）和get sb doing sth （e.g. We get the lawn mower working again eventually.）这两个搭配也是存在的，可能与have sb do sth和get sb to do sth意思上有些不同，但这里它们也可以作为答案吗？如何跟学生解释呢？谢谢。

have sb/sth doing sth 表示使某人/某物一直处于做某事的状态

Don't have the machine running.

have sth to do sth 有某事情要做

I have much homework to do.
