Where is Tom? He ____ shopping. (go)

应该是has gone,has gone to go其实也不错,但是太烦琐.
比如,I am going to Shanghai 和I am going to go to Shanghai其实都是对的,但是我们宁愿用第一种用法.上面的道理一样.

has gone

go shopping词组

has gone.

Tom在哪儿？
他去购物了（还没回来）。

go shopping 去购物
have（has) gone shopping 完成时态
因此答案是 has gone 了。

应该是 has gone to go
go shopping 一个延续性动词不可以用作完成时
