语法 语言升级点
Parallelism and tripling for rhetorical effectC2
增强说服力和节奏感，使文章更具文学性或演讲效果。
Three or more parallel structures (words, phrases, or clauses) in succession to emphasise a point and create rhythm. E.g., 'It informs, it entertains, it divides.'
排比（parallelism）和三连式（tripling）是高阶写作中常用的修辞手段，通过重复相似的语法结构来强调观点、建立气势。在议论文中恰当运用，能有效提升文章的表现力，但不可滥用，以免显得浮夸。
例句
It connects strangers, amplifies voices, and challenges authority — all from a pocket-sized device.
它连接陌生人，放大声音，挑战权威——所有这些只需一个口袋大小的设备。
We must question the sources, scrutinise the algorithms, and demand transparency.
我们必须质疑消息来源，审视算法，并要求透明度。
常见错误
✗ It connects strangers, amplifies voices, challenges authority. → ✓ It connects strangers, amplifies voices, and challenges authority.
排比结构通常需要在最后一项前加'and'以保持语法完整，否则成为不合语法的列举。
↑ 提分：8.5分的关键不是堆砌排比，而是让排比服务于观点的推进和节奏的控制，做到形式与内容统一。
Maintaining a personal voice while sustaining a formal registerC2
在保持正式语域的同时树立个人声音，使文章既专业又有温度，体现作者立场。
Using first-person pronouns (I, we) judiciously alongside formal lexis, complex structures, and hedging to project a credible, individual perspective without becoming colloquial.
在议论文中，完全避免'I'会使文章显得生硬，而过度使用又会过于随意。高分段考生懂得有节制地使用第一人称，并搭配正式词汇和复杂句式，以建立可信的个人声音。例如，用'I would argue'代替'I think'，用'In my view'引入观点，同时保持整体语域的严谨。
例句
I would argue that, while the platform has its flaws, its contribution to democratising speech cannot be overlooked.
我认为，尽管该平台有缺陷，但它对言论民主化的贡献不容忽视。
In my view, the solution lies not in silencing voices but in equipping users with the tools to discern truth.
在我看来，解决办法不是压制声音，而是让用户具备辨别真伪的工具。
常见错误
✗ I think social media is good because it lets people talk. → ✓ I believe that social media, for all its shortcomings, has fundamentally expanded the public sphere.
'I think'过于口语化且缺乏论证力度；应替换为更正式的'I believe/I would argue'，并展开说明理由。
↑ 提分：个人声音的建立依赖于观点的独特性和语言的精确性，而非'I'的频率。每个'I'出现时都应服务于论证，而非单纯表达喜好。

Is Social Media a Boon or Bane for Public Discourse?
It is a truth almost universally acknowledged that social media has revolutionised the way we communicate. Never before has the average citizen possessed a platform that can, in theory, reach millions. Yet, as with most revolutions, the reality is far more complex than the rhetoric suggests.
On one hand, the democratisation of speech is undeniably a powerful good. Voices that were once silenced or ignored—those of dissidents, marginalised communities, and grassroots campaigners—can now find a global audience. The #MeToo movement, for instance, gained momentum through platforms that allowed survivors to share their stories without traditional gatekeepers. This is, quite simply, an expansion of democratic participation.
On the other hand, the same mechanisms that empower the voiceless also amplify the hateful, the misleading, and the inflammatory. Algorithms designed to maximise engagement naturally promote content that triggers strong emotional reactions, which all too often means divisive, sensational, or outright false material. The result is a public square that can feel less like a forum for rational debate and more like a cacophony of shouting matches.
A further, often overlooked, concern is the erosion of nuance. Complex issues are reduced to 280-character slogans, and the middle ground—where most real solutions lie—becomes an increasingly lonely place. Those who attempt to offer balanced views are often vilified by both sides, leaving the discourse dominated by the fringes.
So, is social media a boon or a bane? It is, in truth, both. The question is not whether the technology is inherently good or evil, but whether we, as a society, are capable of using it with the wisdom and restraint it demands. The answer, I suspect, is still very much a work in progress.
cacophony刺耳的嘈杂声fringes边缘；极端派

情景：一个导师和两名学生讨论社交媒体对公共讨论的影响（Section 3）
Tutor
So, last week we talked about the democratising potential of social media. Ben, you were sceptical. Care to elaborate?
Ben
Yeah, look, the idea that everyone gets a voice is great in theory, but I think we're confusing volume with value. Just because more people can speak doesn't mean the quality of discourse improves. Often, it just means the loudest, most extreme voices dominate.
Tiffany
I see your point, but isn't that a bit pessimistic? I mean, without these platforms, many important stories would never see the light of day. Think of citizen journalism in conflict zones.
Ben
Oh, I don't deny the upside. I'm just saying it's not an unmitigated good. The same technology that shares citizen journalism also shares conspiracy theories. And the algorithms don't distinguish between the two. They just push whatever gets the clicks.
Tutor
That's a fair point about the algorithms. Tiffany, how would you respond to that?
Tiffany
Well, I suppose I'd say the answer isn't to throw the baby out with the bathwater. We need better digital literacy, not just a retreat from online spaces. Users need to learn to evaluate sources themselves.
Ben
That's easier said than done, though, isn't it? Most people don't have the time or the skills to fact-check everything they read.
Tiffany
Granted, but that's where education comes in. If we treat media literacy as a fundamental skill, like maths, we might see a shift over time.
MCQ1.What is Ben's main criticism of social media's impact on public discourse?
- A It silences important voices.
- B It promotes extreme voices over quality.
- C It is too expensive for most people.
✅ B — Ben 说 'volume with value' 混淆，极端声音占主导，即重视音量而非质量。
MCQ2.How does Tiffany counter Ben's argument about citizen journalism?
- A She disagrees entirely and says it never works.
- B She agrees it has problems but highlights its value.
- C She thinks it is more important than any other factor.
✅ B — Tiffany 承认其益处，但认为不应全盘否定，强调需要数字素养。
gap_fill3.Ben says the same technology that shares citizen journalism also shares ___.
✅ conspiracy theories — 原句说 'shares conspiracy theories'。
gap_fill4.Tiffany thinks we need better digital literacy, not just a ___ from online spaces.
✅ retreat — 她说 'not just a retreat from online spaces'。
💡 技巧：注意发言中的让步（Oh, I don't deny the upside...）和比喻（throw the baby out with the bathwater），这些都是 Section 3 常考点。听清说话人是完全同意、部分同意还是部分反对，并抓住其使用的形象化表达。
写作 Writing Task 2 (essay) · 目标 250 词
Some people believe that social media has improved public discourse by giving everyone a voice. Others argue that it has done more harm than good. Discuss both views and give your own opinion.
The rise of social media has sparked a fierce debate about its impact on public discourse. While some celebrate its democratic promise, others lament the coarsening of debate. In truth, both perspectives contain elements of validity, though I would argue that the technology’s net effect depends largely on how we choose to engage with it.
Those who champion social media point to its unparalleled ability to democratise speech. For the first time in history, an individual with a smartphone can broadcast their views to a global audience, bypassing traditional gatekeepers. This has given a platform to marginalised groups and fuelled movements like #MeToo, demonstrating the positive force of unfiltered expression.
Conversely, critics rightly note that the same platforms often reward outrage over reason. Algorithms designed to maximise engagement amplify divisive content, while the anonymity of the internet encourages incivility. The result is a fragmented public sphere where misinformation spreads faster than truth, and complex issues are reduced to simplistic slogans. In this light, social media appears to corrode rather than enhance public discourse.
My own view is that we should resist the temptation to treat the technology as a monolithic entity. Social media is a tool, and like any tool, its impact depends on its wielder. The real challenge lies not in the platforms themselves but in our collective willingness to demand accountability, promote digital literacy, and cultivate a culture of reasoned debate. The future of public discourse, I believe, rests not in our devices, but in our hands.

口语 Speaking
Part 1
Q: How often do you use social media?
I'd say I'm a moderate user. I check it most days, but I try not to let it eat into my time. I use it mainly to stay in touch with friends and to catch up on news, though I'm increasingly selective about which sources I follow.
💡 使用 moderate, selective 等词，语气轻松但用词精准。
Q: Do you think social media has changed the way people communicate?
Absolutely. It's made communication more immediate and more casual, but also more fragmented. People now share snippets of their lives rather than having long, in-depth conversations. I think there's a trade-off: we're more connected in quantity, but perhaps less in quality.
💡 使用 fragmented, trade-off 等课内词汇，观点平衡。
Part 2 · 提示卡
Describe a time when you saw an interesting debate on social media. You should say: what the topic was; which platform it was on; what different opinions were expressed; and explain why it made an impression on you.
A debate that really sticks in my mind was on Twitter, about whether artificial intelligence will ultimately benefit or harm society. It started with a prominent tech entrepreneur posting a very optimistic thread, and then a philosopher jumped in with a scathing rebuttal. What fascinated me was how quickly the conversation polarised. One side painted an almost utopian future, while the other warned of existential risks. What struck me most, though, was the lack of middle ground. Anyone trying to offer a balanced view was immediately attacked by both camps. It was a perfect illustration of how social media can turn a complex, nuanced issue into a binary slugfest. I came away feeling that the platform itself, with its character limit and like-button psychology, was partly to blame for the tone. It made me far more cautious about engaging in online debates myself.
💡 流畅叙述，使用 vivid vocabulary (scathing rebuttal, polarised, binary slugfest)，并有个人反思，符合8.5口语要求。
Part 3
Q: Do you think social media encourages people to express extreme views?
To a certain extent, yes. The design of these platforms—the algorithms, the anonymity, the instant feedback—creates an environment where provocative statements get far more traction than measured ones. It's not that everyone becomes extreme, but the loudest voices often are. That said, I wouldn't want to overstate it. Plenty of people use these spaces for constructive discussions. The problem is that the architecture itself tends to reward the extreme, not the moderate.
💡 精细让步（To a certain extent, That said），hedging（I wouldn't want to overstate），展现高级话语控制能力。
Q: Should governments regulate social media more strictly?
It's a thorny issue. On one hand, I think there's a strong case for regulation, particularly around data privacy and the spread of verifiably false information that can cause real harm. On the other hand, I'm wary of governments having too much power over speech. The line between regulation and censorship can be very thin. My instinct would be to push for greater transparency from the companies themselves, and to invest heavily in digital literacy, rather than handing over the keys entirely to regulators. But I admit it's a balancing act with no easy answers.
💡 通过权衡利弊展现成熟思维，使用地道表达（thorny issue, thin line, balancing act），口语化但精准。
高频短语
throw the baby out with the bathwater — （习语）不分良莠全盘否定
a balancing act — 平衡之举，需兼顾各方
get far more traction — 获得更多关注/支持
