是的，这里的 from around the country 属于“介词+介词短语”结构，意思是“从全国各地”。如：

She competed against students from around the country. 她和来自全国各地学生竞争。

The craft show attracts exhibitors from around the country. 这次工艺品展览吸引了全国各地的参展商。

类似地也可以说 from around the world（来自世界各地）。如：

The college draws students from around the world. 这所大学吸引了来自世界各地的学生。

Officials from around the country have called to inquire about the program. 全国各地的官员前来咨询这个计划。

The Taj Mahal attracts visitors from around the world. 泰姬陵吸引来自世界各地的游客。

若需加强语气，也可以在 around 前面加上 all。如：

The bombing brought condemnation from all around the world. 此次爆炸事件遭到了全世界的谴责。

The airport bombing brought condemnation from all around the world. 机场爆炸招致全世界的谴责。
