精段精析

　　一群茂腾腾的后生。

　　他们的身后是一片高粱地。①他们朴实得就像那片高粱。

　　咝溜溜的南风吹动了高粱叶子，也吹动了他们的衣衫。

　　他们的神情沉稳而安静。紧贴在他们身体一侧的腰鼓，呆呆地，似乎从来不曾响过。但是：

　　看！——

　　一捶起来就发狠了，忘情了，没命了！②百十个斜背响鼓后生，如百十块被强震不断击起的石头，狂舞在你的面前。骤雨一样，是急促的鼓点；旋风一样，是飞扬的流苏；乱蛙一样，是蹦跳的脚步；火花一样，是闪射的瞳仁；斗虎一样，是强健的风姿。黄土高原上，爆出一场多么壮阔、多么豪放、多么火烈的舞蹈哇——安塞腰鼓！

　　这腰鼓，使冰冷的空气立即变得燥热了，使恬静的阳光立即变得飞溅了，使困倦的世界立即变得亢奋了。

　　使人想起：落日照大旗，马鸣风萧萧！

　　使人想起：千里的雷声万里的闪！

　　使人想起：晦暗了又明晰、明晰了又晦暗、尔后最终永远明晰了的大彻大悟！容不得束缚，容不得羁绊，容不得闭塞。是挣脱了、冲破了、撞开了的那么一股劲！好一个安塞腰鼓！

     It's great fun to explore (探索) new places-it feels like an adventure, even when you know

you're not the first to have been there. But make sure not to get lost or waste time going round

in circles.

     Do the map reading if you're being driven somewhere.It'll be easier if you keep turning the

map so it follows the direction you're traveling in Keep looking ahead so that you can give the

driver lots of warning before having to make a turn, or you'll have to move to the back seat.

     Get a group of friends together and go exploring.You'll need a good map, a compass

(指南针), a raincoat,a cell phone to call for help in case you get lost, and a bit of spare cash

for emergencies (应急现金). Tell someone where you're going before you set out and let

them know what time you expect to be back. The test is in not getting lost, not in seeing how

fast you can go, so always stick together, waiting for slower friends to catch up.

     See if your school or a club organizes orienteering activities, in which you need a map and

a compass to find your way. This can be done as a sport, with teams trying to find the way

from A to B (and B to C, etc. ) in the fastest time, or simply as a spare-time activity. Either

way, it's not only good fun, but a great way to keep fit.
