雅思作文批改到底改什么？很多考生以为只是改语法，其实批改的核心是任务回应、连贯与衔接、词汇多样性、语法准确度四项评分标准。下面用自问自答的方式，把批改流程、常见失分点、提分技巧一次讲透。
一、批改时考官先看什么？
考官拿到一篇Task 2大作文，30秒内就会给出一个初步分数区间，判断依据是：
- 是否直接回答了题目所有要求（Task Response）
- 段落结构是否清晰（Coherence & Cohesion）
如果这两步不过关，词汇和语法再好也难上6.5。
二、任务回应：怎样算“答全了”？
以2024年3月考题为例：
Some people think governments should spend money on developing high-speed railways. Others believe the money should be spent on improving existing public transport. Discuss both views and give your own opinion.
自问：只写“高铁好”算答全吗？
自答：不算。必须双边讨论，且明确给出个人观点，否则TR直接掉到5分。
批改示范：
原句：I believe high-speed railways are very important.
修改：While upgrading current buses and subways can alleviate congestion in the short term, constructing high-speed railways offers a long-term solution by connecting cities and reducing carbon emissions; therefore, I lean towards the former.
三、连贯与衔接：为什么我的逻辑跳跃？
常见错误：一段里出现多个中心思想。
正确做法：
一段只讲一个论点，并用逻辑连接词层层递进。
- 举例：Firstly, high-speed trains shorten travel time. As a result, business efficiency improves. Moreover, this encourages regional economic integration.
四、词汇多样性：背高级词就够了吗？
自问：把important换成paramount就能提分？
自答：不一定。考官更看重话题词汇的精准度。
批改案例：
原句：Trains are good for the earth.
升级：Electric-powered bullet trains emit 75% less CO₂ per passenger-kilometre than diesel buses, mitigating urban air pollution.
亮点：
bullet trains、passenger-kilometre、mitigating都是交通类话题的高频精准词。
五、语法准确度：复杂句越多越好？
误区：堆砌长难句导致错误率飙升。
正确策略：
2:1原则——每两个简单句配一个复杂句，确保零错误。
批改示例：
原句：If government invest more money on railway, it will benefit people and environment.
修改：If governments were to allocate more funds to railway infrastructure, not only would commuters benefit from reduced travel times, but the environment would also gain from lower emissions.
六、常见失分场景对照表
| 失分点 | 官方评语 | 快速修复 |
|---|---|---|
| 偏题 | addresses only parts of the task | 用题干关键词回译法检查 |
| 分段混乱 | presents information with inadequate coherence | 一段一论点+连接词 |
| 词汇重复 | limited range of vocabulary | 同义词替换+话题词升级 |
| 语法错误 | frequent grammatical inaccuracies | 写完留3分钟专查主谓一致 |
七、如何利用批改反馈循环提分？
步骤：
1. 提交作文给官方标准批改（非AI）。
2. 记录所有标记的红色错误，按TR、CC、LR、GRA分类。
3. 48小时内重写同题作文，只改前3个高频错误。
4. 再次提交，直到单项评分稳定在7。
八、实战案例：5.5到7的批改路径
学生原文片段：
Many people think spend money on railway is waste. Because road is enough.
批改后：
Many citizens perceive investment in high-speed railways as wasteful, arguing that existing expressways already meet travel demands.
提升点：
主谓一致、从句嵌套、话题词汇一步到位。
九、最后3个提分冷知识
- 英式拼写+美式拼写混用不扣分，但同一词须统一。
- 括号内缩写如CO₂可算词汇多样性。
- 考官不会数字数，但明显短于250字会直接降档。
