# 26｜人类还是电脑作曲

IELTS 100 · 第 26 / 100 课

## 今日原句

> The participants weren't told **beforehand** whether the tunes were composed by humans or computers, but were asked to guess, and then **rate** how much they liked each one.

::: details 本课抓手 · 需要时看结构与词块
**结构层次：** 先排除信息／任务转折／后续任务

**重点词块：** **beforehand**、**compose**、**rate**

**输出目标：** 不看原句，能沿用本课结构表达一个与你有关的观点。
:::

## 准确理解

参与者事先并不知道这些曲子是人还是电脑创作的。他们需要先猜一猜，再评价自己有多喜欢每一首曲子。

## 难词与同义替换

| 原表达 | 本句含义 | 可替换表达 |
| --- | --- | --- |
| **beforehand** | 事先 | in advance |
| **compose** | 作曲 | write |
| **rate** | 评分、评价 | evaluate |

替换词不一定能在所有语境中机械互换；这里的作用是扩大表达选择，同时保留本句语义。

## 语法骨架

先读懂 · 再分层

**主干与层次：** 参与者事先不知道曲子的来源，只被要求猜测来源，再给喜爱程度评分。

* **先排除信息：** `The participants weren't told beforehand whether the tunes were composed by humans or computers` whether...or... 是“曲子来源”的宾语内容；beforehand 表实验前。
* **任务转折：** `but were asked to guess` 同一个主语 participants 仍在起作用，were asked 是被动。
* **后续任务：** `and then rate how much they liked each one` rate 与 guess 并列；how much 从句说明评分对象是喜爱程度。

先找主语与核心谓语，再把条件、原因或修饰接回去。读到从句时，停一下：它在解释哪个词，还是在限定整个判断？

## 句型语法精讲

### 为什么这样说

两个被动共用 `participants`，把重点放在实验对象得到或没得到的信息；`but` 强调信息被隐去，`then` 说明任务先后。

### 什么场景可以用

介绍实验、面试或培训流程，用“人 `weren't told` + 信息, `but were asked to` + 任务”。先说明哪些信息被控制，再说参与者做什么；需要解释猜测对象时可补 `guess whether` ...。

保留关系 · 替换内容

> `〔参与者〕 weren't told 〔信息〕, but were asked to 〔任务一〕 and then 〔任务二〕.`

### 从仿写看迁移

取自下方「语法句型仿写」第 1 句，可在那里听原声、跟读。

> The volunteers weren't told which design was cheaper, but were asked to choose one and then explain why.

仿写第 1 句中志愿者不知道哪个设计更便宜，只需选择并解释。`which design was cheaper` 是未提供的信息，`choose` 和 `explain` 是按顺序完成的任务。

容易误解的地方

`were asked` 后的 `guess` 与 `rate` 共用 `to`；`whether` ... `or` ... 表两种来源，不是条件 `if`。`how much they liked` 用陈述语序。

**接下来怎么学：** 先在「朗读切分」里带着理解跟读，再到「句型迁移」看结构怎样变化；自己的版本留到最后的「吃透与运用」。

> The students weren't told the answer, but were asked to compare the results and then discuss their ideas.

这是下方仿写第 2 句。先指出它保留了骨架中的哪一层关系，再将人物、事物或情境换成自己的内容；不必把原句所有修饰都搬过来。

## 朗读切分

> The participants weren't told **beforehand** whether the tunes were composed by humans or computers, / but were asked to guess, / and then **rate** how much they liked each one.

先在 `/` 处短暂停顿。重读加粗内容词，虚词只轻轻带过；读到句尾再完整落音。

## 句型迁移

**可复用骨架：** `〔参与者〕 weren't told 〔信息〕, but were asked to 〔任务一〕 and then 〔任务二〕.`

> The volunteers weren't told beforehand which design was cheaper, but were asked to choose one and then explain their reasons.

试着保持这个骨架，把主题换成你的工作、学习或生活，再口头说一句。能替换内容，才算真正掌握结构。

## 吃透与运用

## 课后连听

今天想轻松听，就把本课原句与仿写串起来。这里用于听熟材料，不作为完成本课的必做任务；也可以去听力台自选更多课程。
