课文原文
Late in the afternoon, the boys put up their tent in the middle of a field. As soon as this was done, they cooked a meal over an open fire. They were all hungry and the food smelt good. After a wonderful meal, they told stories and sang songs by the camp fire. But some time later it began to rain. The boys felt tired so they put out the fire and crept into their tent. Their sleeping-bags were warm and comfortable, so they all slept soundly. In the middle of the night, two boys woke up and began shouting. The tent was full of water! They all leapt out of their sleeping-bags and hurried outside. It was raining heavily and they found that a stream had formed in the field. The stream wound its way across the field and then flowed right under their tent!
傍晚时分，男孩子们在田野中央搭起了帐篷。这件事刚做完，他们就在篝火上做了一顿饭菜。他们都饿了，饭菜闻起来很香。饱餐一顿之后，他们围着营火讲故事、唱歌。但过了一段时间，天开始下雨了。男孩子们感到累了，于是他们扑灭篝火，爬进帐篷。他们的睡袋既暖和又舒适，所以他们都睡得很香。半夜时分，两个男孩醒了，开始大喊大叫。帐篷里全是水！他们都从睡袋里跳了出来，赶紧跑到外面。雨下得很大，他们发现田野里形成了一条小溪。小溪蜿蜒流过田野，然后正好从他们的帐篷下面流过！

四、长难句专项解析
句11: 时态交错的复合句
It was raining heavily and they found that a stream had formed in the field.
层次分析：
第一层 (并列关系):
├─ It was raining heavily
│ └─ 过去进行时：描述当时正在下雨的状态
│
└─ they found that...
└─ 宾语从句：发现的内容
└─ a stream had formed in the field
└─ 过去完成时：在"发现"之前已经形成
语法要点：
- 过去进行时 vs 一般过去时：was raining 表示持续状态，found 表示瞬间动作
- 过去完成时 had formed：表示在 found 之前已经发生并完成的动作
- 时态呼应：主句过去时，从句用相应的过去时态
翻译技巧：“雨下得很大，他们发现田野里已经形成了一条小溪”
句12: 动词短语的连用

结构分解：
主语：The stream
谓语1：wound its way (蜿蜒前行)
└─ 宾语：its way
└─ 状语：across the field (横穿田野)
连词：and then (然后)
谓语2：flowed (流淌)
└─ 状语：right under their tent (正好在他们帐篷下)
语言亮点：
- wound its way：拟人化表达，小溪像人一样”蜿蜒前行”
- right under：right 强调”正好、恰恰”，增加戏剧性
- 两个动词连续使用，形成流畅的画面感
