翻译一下这篇英语小短文．．～

An Expedition
Half an hour before daybreak three of the boys assembled, as they agreed, near the old bridge. The fourth, a boy by the name of Tolly, had not turned up. His absence did not greatly surprise the others. They knew that his mother did not want him to come on this expedition into the forest.

Charles, who was the oldest and their accepted leader, waded downstream to the place where their boat was tied up in the shelter of some overhanging bushes. Then he rowed the boat back to the shallow water near the bridge, where the boys loaded it with the provisions, blankets and other things which they were taking on their journey.

Dawn was just breaking as they climbed into their boat and pushed off from the bank. A swift current carried them downstream, so there was no need to row. They took it in turns to keep the boat in the centre of the river. Three hours later they entered the forest where they intended to spend the next few days.

一次探险

天刚刚过拂晓3个男孩就集合起来了,就在他们约定的地点,那座老桥附近.第4个名叫Tolly的男孩却没有出现.他的缺席并没有使其他人感到很大的意外.因为他们知道Tolly的妈妈不愿意让Tolly来参加这个森林探险.

Charles是这个小队里年纪最大而且最被认可的小首领.滠水到下游去找他们隐藏在灌木丛中的小船,然后他把小船划到一个离桥很近的浅滩上.男孩们装上了食物,药品,毯子和一些其他东西以后,便开始了他们的旅程.

他们爬上船离开浅滩时刚刚破晓.水流带着他们向下游走,所以他们并不用去划船.男孩门轮流把船保持在小河正中间.3小时后,他们进入了森林,这正是他们打算留下来过几天的己方.

"上岸弄点茶喝吧."Charles建议:"没人会看见我们在这里."

这里本来是禁止烟火的,但是很少有人来到在这里.

Charles把船拴住了,其他的2个男孩正忙着收集木头来点个火.他们回来时,每人手里都抱了一大把树枝.他们发现Charles看起来有点焦虑不安.

"我们没有带火柴来啊"Charles沮丧的说到:"本来是该Tolly带来的."

这可是个坏消息.最近的商店都离他们有几英里路呢.

一次远征
黎明前半个小时，3个男孩子按照约定在旧桥集合 ，第四个 托里没出现。 他缺席没有使其他人惊讶。他们知道他妈妈不想让他去森林远征。

查理，最大的孩子，也是大家认可的队长，涉水到下游的一个灌木丛隐蔽处，他们系船的地方。他把路上要用的备用品，毯子什么的装上船。

黎明刚刚破晓时他们登船离开了岸边。湍急的水流把他们带到下游，根本不用滑水。他们轮流保持船在河道中心。3小时后，他们到达了他们之前打算好玩几天的森林地区。

“我们登岸烧点茶，”查理建议“没人能发现我们。”

这里森林禁止点篝火，但是人们偶然会这么做。

当查理系船时，另外2个孩子聚集篝火用的柴草。当他们回来时，每个都有一大捆小木柴， 他们发现查理很担心。
