Lesson 60 The future 卜算未来
At a village fair, I decided to visit a fortune-teller called Madam Bellinsky. I went into her tent and she told me to sit down. After I had given her some money, she looked into a crystal ball and said: ‘A relation of yours is coming to see you. She will be arriving this evening and intends to stay for a few days. The moment you leave this tent, you will get a big surprise. A woman you know well will rush towards you. She will speak to you and then she will lead you away from this place. That is all.’ As soon as I went outside, I forgot all about Madam Bellinsky because my wife hurried towards me. ‘Where have you been hiding?’ she asked impatiently. ‘Your sister will be here in less than an hour and we must be at the station to meet her. We are late already.’ As she walked away, I followed her out of the fair.

三、功能语法分析 (Functional Grammar)
3.1 时态系统详解
3.1.1 一般将来时 (Simple Future Tense)
结构: will + 动词原形 或 shall + 动词原形
课文中的例句:
| 例句 | 用法说明 |
|---|---|
| She will be arriving this evening | 将来进行时（表示按计划发生的动作） |
| you will get a big surprise | 纯将来（预测） |
| A woman… will rush towards you | 纯将来（预测） |
| She will speak to you | 纯将来（预测） |
| she will lead you away | 纯将来（预测） |
| Your sister will be here | 将来状态 |
语法要点:
- 一般将来时表示将来发生的动作或存在的状态
- will 用于所有人称，shall 传统上用于第一人称（现代英语中较少见）
- 时间状语：this evening, in less than an hour 等
3.1.2 将来进行时 (Future Continuous Tense)
结构: will be + 现在分词 (-ing)
课文例句:
“She will be arriving this evening”
用法分析:
- 将来进行时表示将来某一时刻或某段时间正在进行的动作
- 课文中的用法：表示按计划、安排即将发生的动作（比 will arrive 更强调动作的持续性）
- 常用于表示”将来某时正在做某事”
对比:
| 时态 | 例句 | 含义 |
|---|---|---|
| 一般将来时 | She will arrive this evening | 她今晚会到（简单陈述） |
| 将来进行时 | She will be arriving this evening | 她今晚将会到来（强调过程，可能已安排好） |
3.1.3 过去完成时 (Past Perfect Tense)
结构: had + 过去分词 (done)
课文例句:
“After I had given her some money”
用法分析:
- 过去完成时表示”过去的过去”发生的动作
- 时间轴：give money（过去的过去）→ look into crystal ball（过去）
- After 引导的从句中用过去完成时，强调动作发生在主句之前
时间轴图解:
过去某时 ──────── had given ──────── looked ──────── 现在
(先发生) (后发生)
3.1.4 现在完成进行时 (Present Perfect Continuous)
结构: have/has been + 现在分词 (-ing)
课文例句:
“Where have you been hiding?”
用法分析:
- 现在完成进行时表示从过去某一时刻开始一直持续到现在的动作
- 强调动作的持续性和未完成性
- 妻子问的是”你这段时间一直在哪里躲着？“，强调动作的持续
对比:
| 时态 | 例句 | 含义 |
|---|---|---|
| 现在完成时 | Where have you hidden? | 你藏到哪里去了？（强调结果） |
| 现在完成进行时 | Where have you been hiding? | 你一直在哪里躲着？（强调过程） |
3.2 will vs be going to 的区别
本课主要使用 will 表达将来，现对比两种将来表达法：
| 用法 | will | be going to |
|---|---|---|
| 预测 | 客观预测，基于看法 | 基于现有证据的预测 |
| 意图 | 临时决定 | 事先计划好的意图 |
| 承诺/威胁 | 常用 | 较少用 |
| 例句 | It will rain tomorrow.（我觉得会下雨） | Look at those clouds! It’s going to rain.（有证据表明要下雨） |
课文中的 will 用法:
- 算命先生的话都是对未来的预测（prediction），使用 will 恰当
- 这些预言没有事先计划的证据，而是基于”水晶球”的神秘预测
“She will be arriving this evening” — 预测未来会发生的事 “you will get a big surprise” — 预言
3.3 时间状语从句详解
3.3.1 After 引导的时间状语从句
课文例句:
“After I had given her some money, she looked into a crystal ball”
语法要点:
3.3.2 The moment 引导时间状语从句
课文例句:
“The moment you leave this tent, you will get a big surprise”
语法要点:
- The moment = as soon as，“一…就…”
- 名词短语用作从属连词，引导时间状语从句
- 类似用法：the minute, the instant, the second
- 时态：从句用一般现在时表将来，主句用一般将来时（主将从现）
3.3.3 As soon as 引导时间状语从句
课文例句:
“As soon as I went outside, I forgot all about Madam Bellinsky”
语法要点:
3.3.4 As 引导时间状语从句
课文例句:

3.4 直接引语与间接引语
3.4.1 直接引语 (Direct Speech)
定义: 直接引用说话人的原话，用引号标注
课文中的直接引语:

‘A relation of yours is coming to see you. She will be arriving this evening and intends to stay for a few days. The moment you leave this tent, you will get a big surprise…’
- 妻子的质问:
‘Where have you been hiding?’ ‘Your sister will be here in less than an hour and we must be at the station to meet her. We are late already.’
直接引语的标点规则:
- 引语前后加引号 ’ ’ 或 ” ”
- 引语前的引述动词（如 said, asked）后常用冒号或逗号
- 引语首字母大写
- 疑问句和感叹句的标点放在引号内
3.4.2 间接引语 (Indirect Speech)
定义: 转述他人的话，不用引号，需进行相应的语法变化
直接引语 → 间接引语转换规则:
| 变化项目 | 直接引语 | 间接引语 |
|---|---|---|
| 人称 | I / you | he / she / they |
| 时态 | 现在时 | 过去时 |
| 时间状语 | now / today / tomorrow | then / that day / the next day |
| 指示词 | this / these | that / those |
| 动词 | say / ask | said / asked |
课文转换示例:
例1 - 陈述句转间接引语:

- 间接：She said (that) a relation of mine was coming to see me.
例2 - 特殊疑问句转间接引语:
- 直接：‘Where have you been hiding?’ she asked.
- 间接：She asked where I had been hiding.
- 注意：疑问语序变为陈述语序

例3 - 祈使含义的间接引语:

- 间接：She said that my sister would be there and that they must be at the station…
3.5 重要句法结构总结
3.5.1 主将从现原则
在时间状语从句和条件状语从句中，用一般现在时表将来：
“The moment you leave this tent, you will get a big surprise.” （从句：一般现在时 leave；主句：一般将来时 will get）
3.5.2 过去分词作后置定语
“a fortune-teller called Madam Bellinsky” (= a fortune-teller who was called Madam Bellinsky)
3.5.3 省略关系代词的定语从句
