A bear has attacked and injured a 10-year-old boy who was hiking with his family in a US national park.

日前，在一家美国国家公园内，一个男孩在与家人一起徒步旅行的时候被熊袭击并受了伤。

The female grizzly bear is believed to have been for aging with a cub when it encountered the family.

据悉，该雌性灰熊在遇到这家人时，正在与其幼崽觅食。

The boy ran away from the bear when it charged out of vegetation towards the family but the bear chased and knocked him to the ground.

当时这只熊从树丛里冲出来攻击了这家人，男孩在跑开后还是被熊追上并扑倒在地。

The incident occurred at Yellowstone National Park, which spans the US states of Wyoming, Montana, and Idaho.

事件发生在黄石国家公园，该公园横跨美国怀俄明州、蒙大拿州和爱达荷州。

The boy's parents used pepper spray to fight off the bear, who is thought to have been defending its cub.

该男孩的父母用胡椒喷雾来对抗熊，据说这只熊当时在保护它的幼崽。

The 10-year-old, who was visiting with his family from Washington state, had "an injured wrist, puncture wounds to the back and wounds around the buttocks" as a result of the incident, the US National Park Service said in a statement.

这家美国国家公园管理局在一份声明中表示，这名10岁的孩子来自华盛顿州，当时正与家人一起参观公园，此事件导致他“手腕受伤，背部受伤，臀部周围有伤”。

"This incident could have been more serious. We applaud the family for travelling in a group, carrying bear spray, and knowing how to effectively use it," Yellowstone National Park Deputy Superintendent Pat Kenney said.

黄石国家公园副园长帕特·肯尼表示：“这一事件本来可能会更严重。我们对这个家庭集体参观、携带防熊喷雾并知道如何有效地使用它表示赞赏。”

Park rangers do not intend to search for the bear since this incident was a surprise encounter.

公园管理员表示他们不打算搜寻这只熊，因为这次事件是一次意外的遭遇。
