双语新闻：近5千名消防人员试图扑灭加州野火 Nearly 5,000 Firefighters Battling California Wildfire

美国西部加利福尼亚州的消防人员表示，人迹罕至、地势险峻以及极强的火势阻碍消防队员控制大规模野火火势的努力。这场野火正威胁着一个著名的国家公园。

将近5,000名消防队员正与这场称为“环火”的大火拼搏，可是不得依赖飞机来减缓火势的蔓延。

美国林务局星期五表示，熊熊的大火波及800多平方公里的地区，烧毁了大约82,000公顷的土地，其中包括优胜美地国家公园的部分地区。

大约三分之一的火势已经得到控制。当局使用一架类似于美军在阿富汗使用的无人驾驶的军机，来提供有关新的火势的信息，否则他们无法观察全面的火势。

美国林务局说，消防队员预计于9月20号以前能全面控制环火的火势。

Firefighters in ((the western U.S. state of)) California say inaccessible, steep terrain and extreme fire behavior are hampering efforts to contain a massive wildfire that is threatening a famous national park.

Nearly 5,000 firefighters are battling the Rim Fire but have had to rely heavily on aircraft to slow the spread of the fire.

The U.S. Forest Service said Friday the massive blaze has swelled to more that 800 square kilometers and consumed about 82,000 hectares of land, including some of Yosemite National Park.

The fire is about one-third contained. Authorities are using an unmanned military Predator drone, similar to those used in Afghanistan, to provide information on new fires they would otherwise not be able to see.

The U.S. Forest Service says firefighters expect to fully contain the Rim Fire by September 20.
