Chapter 10

AI 时代的备考

第十章 · 在 ChatGPT 之前,雅思考生的最大支出是外教和作文批改;现在,所有这些可以用零钱解决。

AI 改变了什么

2023 年以前,备考雅思 / 托福的家庭支出大头通常是:

2024 年以后,这些环节大部分可以用 ChatGPT、Claude 等 AI 工具替代,单人月成本控制在 100-300 元。但 AI 不是万能的——用好 AI 比依赖 AI 更重要。这一章把目前最实用的 AI 工具和使用方法系统讲一遍。

前提

这一章假设你已经至少能用基础英语和 AI 对话。如果连 prompt 都写不出来,建议先用中文 prompt + 让 AI 用英语回答的方式入门。

用 ChatGPT / Claude 模拟口语考官

这是 AI 在备考中最有价值的应用之一。一段 prompt 让 AI 完整扮演雅思考官:

You are an IELTS Speaking examiner. Conduct a full
Speaking test with me, following the exact format:

Part 1: Ask 3 questions each on three topics:
- Hometown
- Work or study
- A hobby

Part 2: Give me a cue card. Wait 1 minute, then
say "Your time starts now" and let me speak for
2 minutes.

Part 3: Ask 4 follow-up questions related to
the Part 2 topic, increasing in abstraction.

Important rules:
- Don't give feedback during the test.
- Speak naturally, like a real examiner.
- After the test ends, evaluate me on Fluency,
  Lexical Resource, Grammatical Range, and
  Pronunciation, with a band score for each.
- Provide 3 specific things I can improve.

Let's begin Part 1.

这种方式的优点:

缺点:

用 Claude / ChatGPT 改写作

作文批改是 AI 最擅长的部分。一段标准 prompt:

You are an IELTS Writing Task 2 examiner with
years of experience. Below is a Task 2 essay
written by a Chinese student.

Topic: [paste topic here]

Essay:
[paste essay here]

Please evaluate the essay using the official
IELTS band descriptors, and provide:

1. Band score for each of the 4 criteria:
   - Task Response
   - Coherence and Cohesion
   - Lexical Resource
   - Grammatical Range and Accuracy

2. Overall band score (rounded to nearest 0.5).

3. Top 3 strengths in this essay.

4. Top 5 specific weaknesses, each with:
   - The exact sentence from the essay
   - Why it's a problem
   - A suggested improvement

5. A revised version of one weakest paragraph,
   keeping the student's main idea but improving
   language quality.

Be honest. Don't be polite. I want a realistic
band score, not encouragement.

使用建议:

陷阱

不要直接背 AI 改写的版本去考试。AI 写的句子模板感比人类写的还强——句式平均长度、过渡词模式都很容易被识别。AI 的作用是反馈而不是替写

用 AI 生成话题语料

口语 P3、写作 Task 2 都需要话题素材。AI 可以快速生成大量素材库:

Help me build IELTS speaking Part 3 talking
points for the topic "Online Learning".

Please provide:
1. 5 specific real-world examples (not generic
   "research has shown" — use actual platforms,
   countries, or studies).
2. 3 distinct viewpoints that I could choose
   from in an answer.
3. 5 advanced vocabulary items relevant to this
   topic, each with a sample sentence.
4. 3 potential follow-up questions an examiner
   might ask.

Make the examples realistic and varied across
different countries and contexts.

把 AI 生成的素材整理到自己的"话题库"里。考前一周过一遍 50 个话题素材,效果远好于背范文。

用 AI 做 Reading / Listening 训练

生成定制阅读练习

Write me an 800-word academic article on
"the impact of remote work on urban migration",
in IELTS Reading style. The article should:
- Use 3-4 specific examples or case studies.
- Include 2 sets of statistics.
- Have a complex argument with at least one
  counter-argument paragraph.
- Match the difficulty of Cambridge IELTS 18.

After the article, please write:
- 4 True/False/Not Given questions
- 4 Matching Headings questions (with 7 headings,
  3 of which are distractors)
- 3 Multiple Choice questions

Provide answers and brief explanations at the end.

这类生成的练习,难度可控、话题可定制,特别适合补特定弱项。

听力 shadow 训练

把任意 TED 演讲或 podcast 内容粘贴给 AI:

I will paste the transcript of an English speech.
Help me identify:
1. The 10 most challenging connected-speech
   moments (where words blend or get reduced).
2. The intonation patterns I should imitate.
3. 5 useful collocations to memorize.

Then create a 5-minute shadowing practice plan
based on this transcript.

对 7+ 口语考生特别有用,因为口语 7+ 要求 "Pronunciation features are used effectively",不只是"能听懂"。

AI 工具不能替代什么

必须明确:AI 不能替代的环节:

心态调整与应试技巧

考前一周心态管理

考场 5 大应试技巧

考完后的事

最后建议

考试只是一份分数,不是你英语的终极证明。考完之后,真正决定你海外学习 / 工作体验的,是你能不能听懂同事的玩笑、能不能在课堂上举手提问、能不能写一份打动招生官的 PS。这些才是英语学习真正的目的。
