Developing ideas 课文精读 · 穿越北美之旅
一、课文原文及逐段翻译
第1段（问候与总起）
Hi Amy,
嗨，艾米，
第2段
We made it! My family and I have managed to cross the North American continent, from western to eastern Canada, in two weeks! I can't wait to share the stories with you.
我们成功了！我和家人用了两周时间，从加拿大西海岸到东海岸，成功横穿了北美大陆！我已经迫不及待想和你分享这次旅行的故事了。
第3段
We started from Vancouver, where we picked up our vehicle for the trip—a home on wheels. It took us where we wanted, when we wanted. Dad did the driving but he has a poor sense of direction. We got lost a few times even with the help of GPS, but eventually we managed to cross the Rocky Mountains. I was hoping to see a bear or even an eagle, but all I saw was a small group of deer. The views were fantastic, though. There were forests, mountains with snowy tops and masses of ice. It's like another world.
我们从温哥华出发，在那里拿到了这次旅行的交通工具——一辆房车。它可以随时带我们去任何想去的地方。爸爸负责开车，但他的方向感很差。有好几次即使用了GPS，我们还是迷了路，但最终我们成功穿越了落基山脉。我本希望能看到一只熊甚至一只鹰，结果却只看到了一小群鹿。不过沿途的景色还是美极了。我们看到森林、白雪皑皑的山峰和大片的冰原。仿佛是到了另一个世界。
第4段
We reached Quebec on the eighth day, where most people speak French. Well, actually, they speak Quebecois, which is a type of Canadian French. The funniest thing happened on that day. I'd fallen asleep, when I heard Dad's phone ringing. He was driving, so I answered it. Guess who it was? Mum! It was then that I realised her seat was empty! How did that happen? Well, while I was sleeping, Dad stopped for some petrol and Mum also got out to take photos, and you can guess the rest ... She was so mad! To cheer her up, we went to a typical Quebec restaurant for lunch. We had the famous "poutine", which is a dish of French fries, fresh cheese and a hot brown sauce called "gravy". It's usually followed by pancakes with maple syrup—delicious!
我们在第八天到达了魁北克，那里大多数人说法语。不过确切地说，他们说魁北克语，这是加拿大法语的一种。那天发生了这趟旅程中最有趣的事。当时我睡着了，忽然听到爸爸的手机响了。他在开车，所以我接了电话。猜猜是谁？是妈妈！直到那时我才意识到她的座位是空的！这是怎么回事？原来，在我睡着的时候，爸爸停车加油，妈妈也下车去拍照，后来的事你肯定能猜到……她气坏了！为了哄她开心，我们去了一家地道的魁北克餐馆吃午饭。我们点了有名的"肉汁奶酪薯条"，这是一道由法式炸薯条、新鲜奶酪和一种叫"肉汁"的褐色热酱汁做成的菜。吃完这道菜，通常还要配枫糖浆煎饼——味道好极了！
第5段
So, we continued our journey east to Montreal, and then on to the capital, Ottawa, where we visited some beautiful old buildings and learned a little of the country's history. Finally, we reached Toronto and went to see the amazing Niagara Falls. The trip was full of surprises and wonderful sights, and we made it all the way across the continent! I can't wait to show you my photos and tell you more when we meet. See you soon!
于是，我们继续向东前往蒙特利尔，接着又到了首都渥太华，在那里我们参观了一些美丽的老建筑，也了解了一点这个国家的历史。最后，我们到达多伦多，去看了令人惊叹的尼亚加拉大瀑布。这趟旅程充满了惊喜和美景，我们一路横穿了整个大陆！我已经等不及要给你看我的照片，见面时再细说。很快见！

五、长难句拆解
【原句 1】We started from Vancouver, where we picked up our vehicle for the trip—a home on wheels.
【主干】We started from Vancouver.
【分层】where 引导非限制性定语从句修饰 Vancouver；破折号后 a home on wheels 为 vehicle 的同位语，解释房车。
【译文】我们从温哥华出发，在那里拿到了旅行用的交通工具——一辆房车。
【考点】where 非限制性定语从句；同位语；破折号解释。
【原句 2】Dad did the driving but he has a poor sense of direction.
【主干】Dad did the driving but he has a poor sense.
【分层】did the driving 中 did 为避免重复代替 drove；but 连接并列句；has 用一般现在时表常态特征。
【译文】爸爸负责开车，但他的方向感很差。
【考点】do 替代词；but 并列；一般现在时表特征。
【原句 3】I'd fallen asleep, when I heard Dad's phone ringing.
【主干】I'd fallen asleep, when I heard ... ringing.
【分层】I'd fallen asleep = I had fallen asleep（过去完成时，先于 heard）；when 在此不表"当……时"而表"突然、就在这时"；hear ... ringing 为 hear + 宾语 + 现在分词宾补。
【译文】我睡着了，忽然听到爸爸的手机响了。
【考点】过去完成时；when 表"突然"；hear + doing 宾补。
【原句 4】It was then that I realised her seat was empty!
【主干】It was then that I realised ...（强调句）
【分层】It was ... that ... 为强调句型，强调时间状语 then；realised 后接省略 that 的宾语从句 her seat was empty。
【译文】直到那时我才意识到她的座位是空的！
【考点】It is/was ... that ... 强调句；嵌套宾语从句。
【原句 5】... which is a dish of French fries, fresh cheese and a hot brown sauce called "gravy".
【主干】... which is a dish of French fries, fresh cheese and a hot brown sauce.
【分层】which 引导非限制性定语从句修饰 poutine；called "gravy" 为过去分词作后置定语修饰 sauce。
【译文】……那是一道由炸薯条、新鲜奶酪和一种叫"肉汁"的褐色热酱汁做成的菜。
【考点】which 非限制性定语从句；过去分词作定语。
六、语法点清单
1. 非限制性定语从句（where / which）
where we picked up ...；which is a dish of ...。注意 where 指地点、which 指代事物，逗号隔开。
2. 过去完成时（had fallen）
I'd fallen asleep 先于 heard 发生，用于"过去的过去"。
3. 强调句型 It was ... that ...
It was then that I realised ...。强调时间 then。
4. hear / see + 宾语 + 现在分词（宾补）
heard Dad's phone ringing。ringing 表动作正在进行。
5. 过去分词作后置定语
a hot brown sauce called "gravy"。called 表被动"被称作"。
6. 并列连词 but / and / or
Dad did the driving but ...；French fries, fresh cheese and a hot brown sauce。连接并列句与并列成分。
七、逻辑链
开场（第1—2段）：问候艾米 → "我们成功了"，两周横穿北美大陆
↓
西段（第3段）：温哥华取房车 → 落基山脉迷路终穿越、景美如异世界
↓
中段趣事（第4段）：第八天到魁北克 → 妈妈被落下的搞笑插曲 → 肉汁奶酪薯条+枫糖饼
↓
东段收尾（第5段）：蒙特利尔→渥太华→多伦多尼亚加拉瀑布 → 全程惊喜、盼相见
这是一篇"旅行书信"记叙文：以时间顺序展开，第2—3段写西部启程与落基山脉之行；第4段是幽默高潮（妈妈被遗忘）；第5段写东部城市直至瀑布，收束于"成功横穿"的满足与对友人的思念，结构清晰、首尾呼应。
