By Air

原文

I used to travel by air a great deal when I was a boy. My parents used to live in South America and I used to fly there from Europe in the holidays.

A flight attendant would take charge of me and I never had an unpleasant experience. I am used to traveling by air and only on one occasion have I ever felt frightened.

After taking off, we were flying low over the city and slowly gaining height, when the plane suddenly turned round and flew back to the airport.

While we were waiting to land, a flight attendant told us to keep calm and to get off the plane quietly as soon as it had touched down. Everybody on board was worried and we were curious to find out what had happened.

Later we learnt that there was a very important person on board. The police had been told that a bomb had been planted on the plane. After we had landed, the plane was searched thoroughly. Fortunately, nothing was found and five hours later we were able to take off again.

译文

我小时候经常乘飞机旅行。我的父母过去住在南美洲，我在假期里常常从欧洲飞到那里。

一位空中小姐会负责照顾我，我从来没有遇到过不愉快的经历。我已经习惯了乘飞机旅行，只有一次我感到害怕。

起飞后，我们低空飞过城市，慢慢地爬升，这时飞机突然转弯，飞回了机场。

在我们等待降落时，一位空中小姐告诉我们保持冷静，并且一着陆就安静地离开飞机。机上的每个人都感到担心，我们都好奇地想知道发生了什么事情。

后来我们得知，机上有一位非常重要的人。警察被告知飞机上安放了一枚炸弹。着陆后，飞机被彻底搜查。幸运的是，什么也没发现，五小时后我们又起飞了。

关键句型 "used to + verb"

定义

此句型用于描述过去经常发生的习惯或状态，但现在已不再存在。结构为：used to（过去常常）+ verb（动词原形）。例如，在文章中如 "I used to travel by air" 表示过去的经常性行为。根据《剑桥英语语法》，这个句型专用于过去，与现在形成对比，帮助表达个人经历的改变。

它是一种简单有效的表达方式，适合描述童年回忆或生活变化。

用法

此句型主要用于叙述过去习惯性动作或情况，常出现在个人故事、回忆录或对话中。规则：主语 + used to + 动词原形，例如 "I used to live there"。在语法体系中，它属于过去习惯的表达，与一般过去时（Simple Past）相关，但used to 强调习惯性而非具体事件。

横向比较：与 Simple Past（如 "I traveled last year"）相比，used to 突出重复性习惯（例如 "I used to travel every summer" vs. "I traveled once"）；与现在习惯表达如 "I usually + verb" 相比，它专注于过去。另外，与 would + verb 类似（如文章中的 "A flight attendant would take charge"），两者都表示过去习惯，但used to 更适合状态或动作，而would + verb 常用于动作序列，建立联系可帮助学生区分细微差异。

跨语法知识：它常与时间状语如 "when I was a boy" 结合，学生可扩展到其他过去时态的学习。

注意事项

学生容易犯的错误包括将 used to 与 use to 混淆（例如在疑问句或否定句中说 "Did you used to...?" 应为 "Did you use to...?"）；或误用为现在习惯，如 "I used to go now"，这是不正确的。纠正建议：记住 used to 只用于肯定句的过去形式，并在练习中多用否定和疑问形式，例如 "I didn't use to like flying" 或 "Did you use to travel a lot?"。

另一个常见偏误是与 be used to 混淆，后者表示习惯于某事（见语法点）。提供例句：

错误示例：I use to play football every day. (应为过去时)
正确示例：I used to play football every day when I was young.

练习

原创例子：假设你在分享童年经历，可以说："I used to ride my bike to school every morning." 学生可以替换动词和内容，例如改成 "She used to read books before bed"，或调整为自己的经历如 "We used to visit grandparents on weekends." 这能帮助学生在日常对话中应用句型，增强记忆。

通过替换关键词，学生能探索不同场景，如旅游或学习习惯，促进实际使用。

额外内容

背景知识：used to 起源于中古英语，用于强调过去与现在的对比，在英语文学中常见，如狄更斯的作品中描述维多利亚时代的生活。文化背景：英语国家的人常在自传或故事中用此句型回忆童年，对比分析，与西班牙语的 "solía + verb" 类似，都表达过去习惯，但英语版本更简单，无需动词变位。这能让学生理解英语的灵活性，并为学习更复杂句型如条件句铺路。
