B节：控制性写作（20分，120-150词）
B节通常要求根据所给情景、图表或提纲写一篇议论文或说明文。文章结构要清晰（通常为三段论），逻辑严密。最常见的类型是：现象评论/看图作文、观点论述、图表描述。
1. 现象评论/看图作文
题目要求： 描述年轻人喜欢点外卖（ordering food online）而不是自己做饭的现象，分析原因，并给出你的看法。
Nowadays, ordering food online has become increasingly popular among young people. It is a common phenomenon that many office workers and students prefer food delivery to cooking by themselves.
There are two main reasons for this trend. First of all, the fast pace of modern life puts young people under great pressure. After a busy day, they are often too tired to cook. Furthermore, food delivery apps offer various choices and great convenience.
In my opinion, while ordering food online brings convenience, we should not ignore its disadvantages, such as food safety issues. Therefore, it is advisable to cook for ourselves when we have free time.
2. 观点论述题
题目要求： 有人认为金钱是生活中最重要的东西，有人则不同意。写一篇短文表明你的观点并给出理由。
When it comes to the importance of money, people hold different views. Some believe money is the most important thing in life, while others disagree. From my perspective, money is necessary, but it is not everything.
On the one hand, we need money to survive. It provides us with basic needs such as food, housing, and education. On the other hand, there are many precious things that money cannot buy, such as true friendship, good health, and true happiness. A wealthy person may suffer from illness or loneliness.
To sum up, we should work hard to earn a living, but we must never become slaves to money. We should cherish the things that truly matter in life.
3. 图表描述题
题目要求： 描述过去几年人们出行方式的变化（私家车增多，自行车减少），分析原因及影响。
As is clearly shown in the chart, there has been a dramatic change in people's ways of traveling over the past few years. The proportion of people driving private cars has increased rapidly, while the number of people riding bicycles has decreased significantly.
Several factors account for this change. First, with the improvement of living standards, more and more families can afford to buy cars. Second, driving is much faster and more comfortable than riding a bike, especially in bad weather.
However, the increase in cars has caused serious problems such as traffic jams and air pollution. Therefore, the government should encourage citizens to use public transportation or ride bicycles to protect the environment.
📊 评分标准
考官从以下三个维度打分，缺一不可：
| 维度 | 说明 | 高分要点 |
|---|---|---|
| 内容完整性 | 任务点全部覆盖 | Section A 逐条对应题目给出的 3-5 个交际任务；Section B 三段结构完整 |
| 语言准确性 | 减少拼写与语法错误 | 重点保证主谓一致、时态一致；避免中式英语 |
| 连贯性 | 逻辑层次清晰 | 熟练使用连接词：Firstly / In addition / However / Consequently / To sum up |
🎯 备考建议
:::tip 高分策略
- 背诵功能句型：Section A 的万能开头句（如 I am writing to express my gratitude for...）每类至少背一句
- 控制作答时间：建议 Section A 用 15 分钟，Section B 用 25 分钟，留 5 分钟检查
- 字数不要超：Section B 写到 140 词左右即可，写太多容易因赶时间出现低级错误
- 卷面整洁：2026 年以人工阅卷为主，字迹清晰能留下良好印象，涂改不超过 3 处
- 任务点先列再写：拿到题目后，先在草稿纸上列出所有任务点，逐一打勾，确保无遗漏 :::
