课文原文
I love travelling in the country, but I don’t like losing my way. I went on an excursion recently, but my trip took me longer than I expected. ‘I’m going to Woodford Green,’ I said to the conductor as I got on the bus, ‘but I don’t know where it is.’ ‘I’ll tell you where to get off,’ answered the conductor. I sat in the front of the bus to get a good view of the countryside. After some time, the bus stopped. Looking round, I realized with a shock that I was the only passenger left on the bus. ‘You’ll have to get off here,’ the conductor said. ‘This is as far as we go.’ ‘Is this Woodford Green?’ I asked. ‘Oh dear,’ said the conductor suddenly. ‘I forgot to put you off.’ ‘It doesn’t matter,’ I said. ‘I’ll get off here.’ ‘We are going back now,’ said the conductor. ‘Well, in that case, I prefer to stay on the bus,’ I answered.

三、时态与语态分析 (Tense & Voice)

3.2 核心时态详解
3.2.1 一般过去时 - 叙述主线
时态标志:讲述已经发生的事情
本课例句:
- I went on an excursion recently.(一般过去时)
- my trip took me longer than I expected.
- I said to the conductor...
- the bus stopped.
- I realized with a shock...
用法要点:
1. 一般过去时用于叙述过去发生的事件
2. 与recently, last week, yesterday等时间状语连用
3. 课文整体采用过去时态,营造讲故事的氛围
3.2.2 现在进行时表将来
结构:am/is/are + doing
本课例句:
1. "I'm going to Woodford Green"
= I will go to Woodford Green(按计划要去)
2. "We are going back now"
= We will go back now(马上要回去)
用法要点:

- 现在进行时表将来:强调"计划性"、"安排好"
- will/shall:强调"意愿"、"临时决定"
3.3 语态分析
本课文主要使用主动语态,无被动语态用例。这是因为故事以第一人称叙述,强调”我”的动作和经历。
四、从句专项分析 (Clauses)
4.1 宾语从句
4.1.1 由where引导的宾语从句
例句1: I don't know where it is.
结构分析:
主句: I don't know [宾语从句]
从句: where it is(陈述语序)
注意:
- 宾语从句用陈述语序(主语+谓语)
- 不是:where is it(疑问语序)
例句2: I'll tell you where to get off.
(疑问词+不定式结构,参见下文)
4.1.2 由that引导的宾语从句
例句: I realized with a shock that I was the only passenger left on the bus.
结构分析:
主句: I realized with a shock [宾语从句]
从句: that I was the only passenger left on the bus
注意:
- that在宾语从句中可省略,但在正式文体中保留
- realize that... = 意识到...
- with a shock 为方式状语,修饰realized
4.2 比较状语从句
4.2.1 由than引导的比较状语从句
例句: my trip took me longer than I expected.
完整形式: my trip took me longer than (it was) I expected.
结构分析:
- longer: 形容词比较级
- than I expected: 比较状语从句
用法要点:
1. 比较级 + than + 从句(陈述语序)
2. 从句中常省略与主句相同的成分
3. 比较对象要一致:trip的时间 vs 我预期的时间
4.2.2 as…as 原级比较
例句: This is as far as we go.
结构分析:
- as far: 表语(far的原级)
- as we go: 比较状语从句
用法要点:
1. as + 形容词/副词原级 + as = 和...一样
2. 本句为特殊用法:as far as = 远到...程度
"这是我们走的极限距离"
3. 否定形式:not as/so...as(不如...)
4.3 时间状语从句
例句: as I got on the bus
结构分析:
- as: 时间连词,"当...时"
- 强调两个动作同时发生:"上车时"与"说话"
as的多种用法:
1. 时间:当...时(本课用法)
2. 原因:因为(As it was raining, we stayed home.)
3. 方式:按照...(Do as I say.)
4. 让步:尽管(Young as he is, he knows a lot.)
五、非谓语动词专题 (Non-finite Verbs)
5.1 动名词(Gerund)- 本课核心语法
5.1.1 动名词作宾语
【核心语法】love/like + doing
本课例句:
1. I love travelling in the country.
love + travelling(动名词作宾语)
= 我喜欢在乡间旅行
2. I don't like losing my way.
like + losing(动名词作宾语)
= 我不喜欢迷路
用法要点:
1. 某些动词后必须接动名词作宾语,不能接不定式:
- enjoy doing(喜欢做)
- finish doing(完成做)
- avoid doing(避免做)
- consider doing(考虑做)
- suggest doing(建议做)
- mind doing(介意做)
- practice doing(练习做)
2. love/like 后接动名词与不定式的区别:

- love/like to do:表示一次性、特定场合的意愿
例:
- I like swimming.(我喜欢游泳 - 爱好)
- I'd like to swim this afternoon.(我今天下午想去游泳 - 意愿)
5.1.2 动名词与现在分词的区别
| 特征 | 动名词(Gerund) | 现在分词(Present Participle) |
|---|---|---|
| 词性 | 名词性 | 形容词/副词性 |
| 功能 | 作主语、宾语、表语 | 作定语、状语、补语 |
| 含义 | 表示抽象动作 | 表示正在进行的动作 |
| 例句 | I love travelling.(宾语) | Looking round, I realized…(状语) |
5.2 疑问词 + 不定式结构
【核心语法】疑问词 + to do = 名词性短语
本课例句:
"I'll tell you where to get off"
= I'll tell you [where to get off]
= I'll tell you [where you should get off](宾语从句简化)
结构分析:
- where: 疑问词
- to get off: 不定式
可用疑问词:
- what to do(做什么)
- where to go(去哪里)
- how to do it(如何做)
- when to start(何时开始)
- which to choose(选哪个)
- whether to go(是否去)
用法要点:
1. 相当于一个简化的宾语从句
2. 主语必须是泛指的(you/one/people)或从上下文可知
3. 不能用于有明确主语的情况
正:I don't know what to do.(我不知道该做什么)
正:I don't know what I should do.
误:I don't know what he to do.(×)
5.3 不定式(Infinitive)
5.3.1 不定式作目的状语
例句: I sat in the front of the bus to get a good view of the countryside.
结构分析:
- to get: 不定式作目的状语
- = in order to get(为了获得)
- = so that I could get(目的状语从句)
用法要点:
1. 不定式可作目的状语,表示"为了..."
2. 可放在句首或句末
3. 否定形式:in order not to / so as not to
例:
- He came here to see you.(他来这儿是为了见你)
- To pass the exam, you must work hard.
(为了通过考试,你必须努力学习)
5.3.2 不定式作宾语
本课例句:
1. I forgot to put you off.
forget + to do(忘记去做某事)
2. I prefer to stay on the bus.
prefer + to do(宁愿做某事)
【易混点】forget to do vs forget doing
forget to do sth.:
- 忘记去做某事
- 事情还没有做
- 例:I forgot to lock the door.(我忘了锁门 - 门没锁)
forget doing sth.:
- 忘记做过某事
- 事情已经做了,但忘记了
- 例:I forgot locking the door.(我忘了锁过门 - 门已锁)
类似用法的动词:
- remember to do(记得去做)vs remember doing(记得做过)
- stop to do(停下来去做)vs stop doing(停止做)
- try to do(努力做)vs try doing(尝试做)
5.4 分词(Participle)
5.4.1 现在分词作伴随状语
例句: Looking round, I realized with a shock that...
结构分析:
- Looking round: 现在分词短语作伴随/时间状语
- = When I looked round(时间状语从句简化)
- 现在分词的逻辑主语与主句主语一致(I)
用法要点:
1. 现在分词作状语,表示与主句动作同时发生
2. 逻辑主语必须与主句主语一致
3. 可表示时间、原因、条件、伴随等
例:
- Walking in the park, I met an old friend.
(在公园散步时,我遇到了一位老朋友 - 时间)
- Being tired, I went to bed early.
(因为累了,我早早就睡了 - 原因)
5.4.2 过去分词作后置定语
例句: I was the only passenger left on the bus.
结构分析:
- left: 过去分词作后置定语,修饰passenger
- = who was left(定语从句省略)
- = remaining(剩下的)
用法要点:
1. 过去分词作定语,表示被动或完成
2. 单个过去分词作定语可前置或后置
- 前置:a broken cup(一只破杯子)
- 后置:the only passenger left(唯一剩下的乘客)
3. 过去分词短语通常后置
例:
- The book written by Lu Xun is famous.
(鲁迅写的那本书很有名)
- Most people invited to the party were my friends.
(被邀请参加聚会的大多数人都是我的朋友)
六、特殊句式与结构 (Special Structures)
6.1 直接引语与间接引语
本课特点:大量对话,使用直接引语
直接引语特征:
1. 使用引号标明原话
2. 保留原话的时态和人称
3. 常用say, ask, answer等动词引导
本课例句分析:
1. "I'm going to Woodford Green," I said to the conductor...
- 引号内为直接引语
- 主句用过去时(said),引语用现在进行时表将来
2. "I'll tell you where to get off," answered the conductor.
- 主句倒装:answered the conductor(主语为名词时可倒装)
- 引语用一般将来时
直接引语变间接引语的要点:
1. 去掉引号,用that/if/whether等连接
2. 人称变化:I → he/she, my → his/her
3. 时态变化:一般现在时→一般过去时,现在进行时→过去进行时等
4. 时间/地点变化:now → then, here → there等
6.2 倒装结构
本课例句:
1. "I'll tell you where to get off," answered the conductor.
2. "Oh dear," said the conductor suddenly.
结构分析:
- 谓语动词 + 主语(倒装)
- 条件:主语为名词(the conductor),且谓语为said/answered等
正常语序:
- the conductor answered
- the conductor said
完全倒装 vs 部分倒装:
1. 完全倒装:谓语全部置于主语前(本课用法)
Here comes the bus.
2. 部分倒装:助动词置于主语前
Never have I seen such a thing.
倒装条件:
1. 主语为名词(非代词)
2. 谓语为不及物动词(如come, go, sit, stand, lie等)
3. 常见于文学描写,使语言更生动
6.3 常用句型与表达
6.3.1 固定搭配
| 搭配 | 含义 | 例句 |
|---|---|---|
| lose one’s way | 迷路 | I don’t like losing my way. |
| go on an excursion | 去短途旅行 | I went on an excursion recently. |

七、易错点与考点精析 (Error Analysis)
7.1 动名词 vs 不定式(作宾语)
【高频考点】某些动词后只能用动名词,某些只能用不定式
只接动名词的动词:
✓ enjoy doing ✗ enjoy to do
✓ finish doing ✗ finish to do
✓ avoid doing ✗ avoid to do
✓ consider doing ✗ consider to do
✓ mind doing ✗ mind to do
✓ practice doing ✗ practice to do
只接不定式的动词:
✓ want to do ✗ want doing(表被动除外)
✓ decide to do ✗ decide doing
✓ hope to do ✗ hope doing
✓ plan to do ✗ plan doing
✓ afford to do ✗ afford doing
两者皆可,意义不同:
1. remember/forget/regret
- remember to do: 记得去做(未做)
- remember doing: 记得做过(已做)
2. stop
- stop to do: 停下来去做另一件事
- stop doing: 停止正在做的事
3. try
- try to do: 努力做
- try doing: 尝试做
本课应用:
- I forgot to put you off.(忘记去做 - 用to do)
- I love travelling...(爱好 - 用doing)
7.2 疑问词 + 不定式的使用条件
【易错点】并非所有情况都可用疑问词+不定式
可用:
✓ I don't know what to do.
✓ Can you tell me how to get there?
✓ I wonder where to put it.
不可用(必须有明确主语):
✗ I don't know what he to do.(×)
✓ I don't know what he should do.(√)
总结:
疑问词+不定式结构中,不定式的逻辑主语必须是泛指的(you/one)
或从上下文可以推断。如果有明确的特定主语,必须用从句。
7.3 比较状语从句的省略
【易错点】比较从句中的省略
原句:my trip took me longer than I expected.
完整:my trip took me longer than (it was) I expected (it was).
易错:
✗ my trip took me longer than I expected it.
(比较对象不一致:trip vs I)
✓ my trip took me longer than expected.
(省略了主语和be动词,比较对象一致)
其他省略情况:
- He is taller than I (am).
- She runs faster than I do.
- I have more books than he (does).
7.4 四级真题链接
【四级考点】动名词与不定式是四级必考点
真题示例(改编):
1. I really appreciate ______ to help me, but I am sure
that I can manage by myself.
A. you to offer B. your offering
C. that you offer D. that you are offering
答案:B
解析:appreciate后接动名词,your offering为动名词复合结构
2. The old man regretted ______ the chance to go to college.
A. to waste B. wasting
C. to have wasted D. having wasted
答案:D
解析:regret doing表示"后悔做过",用完成式强调动作已发生

答案:B
解析:how to do = 如何做,疑问词+不定式结构
