📝 雅思写作强化课第5课

大作文第一课 · Task 2 总览（题型识别 / 万能结构 / 开头段写法）· 250词 · 提分主战场

强化课 5/8 · 大作文第一课
🔥
一、Engage 热身Warm-up
小作文 vs 大作文：大作文才是提分主战场
▼
维度小作文 Task 1大作文 Task 2
字数≥ 150 词≥ 250 词
考什么图表 / 图形的客观描述对一个观点 / 问题的论述
评分权重占写作总分 1/3占写作总分 2/3（更重要）
核心能力准确描述 + 数据对比审题 + 论证 + 立场 + 逻辑
常见陷阱过度解读 / 写个人观点偏题 / 立场摇摆 / 论证空泛
📌 今天的主线：小作文四讲已收口（线图 / 柱图 / 静态三图 / 特殊图形）。从本课起进入大作文 Task 2——它占写作 2/3 权重，是提分主战场，也是多数人卡 6 分的瓶颈。本课先打地基：认清题型 → 搭对结构 → 写好开头段。主体段怎么论证，留到第6课细讲。
🧭
二、题型识别
大作文五大题型家族（先会"认题"）
▼
题型识别标志词（题目里出现这些＝这类）你要做什么
① Opinion
立场类		To what extent do you agree or disagree?
Do you agree or disagree?		明确表态（同意/反对/部分），全文支撑该立场
② Discussion
讨论类		Discuss both views and give your own opinion.双方都讨论 + 亮出自己观点
③ AD
利弊类		Do the advantages outweigh the disadvantages?利弊都写 + 给出倾向
④ Problem & Solution
问题解决		What are the causes? / What measures can be taken?分析原因/问题 + 提对策
⑤ Two-part
双问类		Why is this? / Is this a positive or negative development?题目问几个问题，就答几个（常 2 问）
💡 真题长这样（选自《剑桥雅思》Task 2）：
· Discussion：In a number of countries, some people think it is necessary to spend large sums of money on constructing new railway lines for very fast trains between cities. Others believe the money should be spent on improving existing public transport. Discuss both these views and give your own opinion.
· Advantages & Disadvantages：At the present time, the population of some countries includes a relatively large number of young adults, compared with the number of older people. Do the advantages of this situation outweigh the disadvantages?
❓
三、审题（核心武器）
审题三问：动笔前先回答这三个问题
▼
① 这是哪类题？
题干出现 Discuss both views and give your own opinion → Discussion 讨论类；出现 outweigh → 利弊类；出现 To what extent → 立场类。
② 我的立场 / 题目问了几个问题？
立场类：必须选边（同意 / 反对 / 折中）。两问类（Two-part）：题目问几个就答几个，漏答直接 TR 掉分。
③ 主体段怎么分？（列提纲）
Discussion：主体段1 写一方观点+理由，主体段2 写另一方+理由，结尾亮自己观点。利弊类：主体段1 利，主体段2 弊，结尾给倾向。
🔍 现场审题示范（高铁题）：
① 题型：Discussion（Discuss both views + your opinion）
② 立场：我倾向"两者结合"——新建高铁连接远城 + 同时升级现有公交覆盖市内
③ 提纲：Para2 支持高铁（快 / 连城 / 经济）；Para3 支持改善公交（惠及日常通勤 / 成本低）；Para4 我的观点＝按国情组合
🏗️
四、文章结构
万能结构：四段式 vs 五段式
▼
结构段落安排适用
四段式
（推荐入门）		① 开头段（改写题+立场）
② 主体段1
③ 主体段2
④ 结尾段（重申立场）		双边讨论 / 利弊 / 立场类，时间紧时最稳
五段式① 开头 ② 主体1 ③ 主体2 ④ 主体3 ⑤ 结尾想多展开一个分论点、或 Two-part 两问各一段
📌 铁律：无论几段，开头段必须含①题目同义改写 ②你的立场/文章走向（thesis）。结尾段必须重申立场（不写新观点）。中间主体段"一段一个中心论点"。
🛠️
五、开头段写法
开头段武器库：paraphrase 三招 + thesis
▼
① 同义替换（最常用）
原题词替换
some people thinkIt is often argued that / A common belief is that
spend large sums of moneyinvest heavily / allocate substantial funds
improving public transportupgrading existing transit systems
② 词性转换
原Some people think it is necessary to spend money on railways.
改There is a necessity to invest in railway construction.
③ 句子重组（换主语 / 语态）
原Some people think we should build high-speed railways.
改The construction of high-speed rail is considered essential by many.
④ thesis + outline（开头段后半）
thesis＝一句话亮立场：From my perspective, a balanced approach is preferable.
outline（可选）＝预告主体段：This essay will examine both sides before concluding that ...
💬
六、句库
完整表达句库（开头 / 立场 / 结尾，直接套）
▼
🏷️ ① 开头段引入

⚖️ ② 立场 / 过渡表达

🧭
七、写作方法
大作文通用三步（本课版）
▼
第一步 · 审题定题型
用"审题三问"套：①哪类题 ②立场/几问 ③主体段怎么分。不确定就回看「二、题型识别」的家族表。
第二步 · 写开头段
paraphrase 题目（三招任选）+ thesis 亮立场。约 2-3 句，50-60 词。
第三步 · 列主体段提纲（暂不展开写）

5 道真题题目 + 填空式同义替换（带做）

🙈 写完再点：参考范例（先自己写，别偷看！）
【开头段示范】
In recent years, the debate over how to allocate transport budgets has intensified. While some argue that substantial funds should be invested in high-speed rail between cities, others contend that existing public transport deserves priority. From my perspective, a balanced approach—building rail for long distances while upgrading urban transit—is preferable.
【主体段提纲示范 · 不写完整论证（第6课教）】
Para 2（支持高铁）：Topic — High-speed rail saves time and boosts inter-city economy. Example — China's HSR cut Beijing–Shanghai trips to ~4.5h.
Para 3（支持改善公交）：Topic — Daily commuters benefit more from better buses/metro. Example — Lower cost, wider coverage for ordinary citizens.
Para 4（我的观点）：Combine both per a country's geography; no one-size-fits-all.

👆 开头段＝paraphrase + thesis 亮立场；提纲＝每段"中心句 + 1 例子"，先把骨架立住，第6课再扩写成论证。

📌 第5课核心口诀（大作文 Task 2 · 地基篇）
