同一個Essay題目，高分同低分嘅寫法爭幾遠？用實例拆解

如果你讀緊大學，一定遇過呢種情況：交完篇 essay 覺得自己寫得唔錯，點知出到嚟個分數同預期爭好遠。明明大家都係答同一條題目，點解有人可以攞 A，有人就得 C？其實關鍵唔係你寫咗幾多字，而係你有冇掌握到學術寫作嘅底層邏輯。好多同學會選擇參考 essay代寫 服務嚟理解高分框架，但無論你係自己寫定係揾人幫手，最緊要嘅係——你要親眼睇到「低分寫法」同「高分寫法」之間嘅實際差距喺邊。今次我哋就用一個假設嘅 essay 題目，逐部分拆解畀你睇清楚。

揀定嘅題目係：「探討社交媒體對青少年心理健康嘅影響」（Discuss the impact of social media on adolescent mental health）。呢條題目屬於典型嘅 argumentative essay，幾乎係大學社會科學、心理學、傳理系嘅必考題型。題目本身唔算難，但就係因為人人都覺得自己識寫，所以更加容易喺唔覺意之間寫出低分版本。想寫好呢類文，可以參考吓 Argumentative Essay 寫作指南 入面講嘅論證結構，但今日我哋集中睇實例。

講解之前，有個概念要先搞清楚：高分 essay 同低分 essay 之間嘅分別，唔係在於你用咗幾多深字、寫咗幾長，而係在於你有冇喺每個段落入面建立一個完整嘅論證鏈。所謂「論證鏈」，就係由 Topic Sentence 去到 Evidence，再去到 Analysis，最後返去扣題——呢個鏈條如果斷咗任何一環，成段就會散。Wikipedia 上面關於學術寫作嘅定義 都提到，academic writing 嘅本質唔係資訊堆砌，而係有邏輯地說服讀者接受你嘅立場。

咁點解咁多同學明明好勤力，都係寫唔出高分 essay 呢？原因通常唔係佢哋唔識英文，而係佢哋將 essay 當咗做「資料整理」而唔係「論證建構」。例如好多人會喺 Google Scholar 搵一大堆文獻，然後每段 quote 一段，再 paraphrase 一下，就以為咁樣就叫寫完。實際上，呢種寫法喺大學嘅評分標準入面，最多只能夠攞到 borderline pass。

講到呢度，不如直接睇實例。以下我哋會用同一個 essay 題目，同時展示低分版本同高分版本，然後逐個位拆解點解一個得、一個唔得。每個對比都會覆蓋 essay 嘅核心組成部分：Introduction、Body Paragraph、同埋 Conclusion。你睇完就會明白，原來由 C 到 A 嘅距離，就係喺呢啲細節位。

Introduction 嘅低分同高分寫法

先睇 Introduction。Introduction 嘅功能好簡單：你係要喺一段之內，話俾讀者知你篇文要討論咩、你嘅立場係咩、同埋你會點樣組織你嘅論證。聽落好基本，但係大部分低分 essay 嘅 Introduction 都做唔齊呢三樣嘢。

以下係一個典型嘅低分 Introduction 版本：

「Social media is very popular among teenagers nowadays. Many young people use Instagram, TikTok and Facebook every day. Some people think social media is bad for mental health, but some people think it is good. This essay will discuss the impact of social media on adolescent mental health. I will talk about both positive and negative effects.」

睇完呢段，你可能覺得「冇問題呀，寫得幾清楚」。但係喺大學嘅評分標準之下，呢段 Introduction 其實有幾個致命傷。第一，佢冇明確立場——"some people think... but some people think..." 呢種寫法等於冇講過你自己點睇，而 argumentative essay 最重要嘅就係你要有一個 arguable thesis statement。第二，佢用咗 "I will talk about" 呢類第一人稱表述，喺學術寫作入面唔係話完全唔得，但高水平嘅 essay 會用更加精準嘅學術語言去 signpost 結構。第三，成段嘅學術深度近乎零——"social media is very popular" 呢句嘢係常識而唔係學術論述，擺喺 Introduction 只會浪費字數。

咁高分嘅 Introduction 應該點寫？睇吓以下版本：

「While social media platforms have become an integral part of adolescent daily life, with over 90% of teenagers in developed countries maintaining at least one active social media account, their psychological implications remain a subject of significant academic debate. Although proponents emphasise the social connectivity and community-building potential of these platforms, a growing body of longitudinal research suggests a correlative, and in some cases causal, relationship between heavy social media usage and declining adolescent mental health indicators. This essay argues that the net psychological impact of social media on adolescents is predominantly negative, particularly when usage exceeds three hours per day. It does so by examining three key mechanisms — social comparison, sleep disruption, and attention fragmentation — before addressing the counter-argument that social media provides essential peer support networks.」

呢段 Introduction 嘅差距喺邊？首先，一個清晰嘅 thesis statement 出現喺第三句："the net psychological impact... is predominantly negative"——讀者一睇就知你嘅立場。第二，佢有 signposting："by examining three key mechanisms... before addressing the counter-argument"——清楚交代咗篇文嘅結構。第三，佢用咗學術詞彙例如 "longitudinal research"、"correlative, and in some cases causal, relationship"、"net psychological impact"，顯示出你唔係喺度講個人意見，而係基於學術文獻去做論證。

如果同學覺得自己好難一下子寫到呢個水平，揾 essay代寫 嘅專業團隊幫手睇一次你嘅 Introduction 框架，可以慳返好多自己摸索嘅時間。要知道 Introduction 定調咗成篇文嘅水平，Marker 睇完第一段已經對你嘅分數有咗一個初步判斷，呢個第一印象係好難之後扭轉嘅。

Body Paragraph 嘅低分同高分寫法——以社會比較為例

Introduction 之後，我哋進入 Body Paragraph 嘅對比。呢度我揀咗「社會比較」（social comparison）呢個論點嚟做示範，因為佢係社交媒體影響心理健康研究入面最常被引用嘅機制之一。

先睇低分版本嘅 Body Paragraph：

「Social media makes teenagers compare themselves with others. When they see their friends posting beautiful photos and having fun, they feel bad about their own lives. This is called social comparison. Research shows that social comparison can lead to depression and low self-esteem. For example, a study by Smith (2020) found that 70% of teenagers feel worse after browsing Instagram. Therefore, social media has a negative effect on teenagers' mental health because of social comparison.」

呢段嘅問題好明顯。首先，Topic Sentence 太薄弱——"Social media makes teenagers compare themselves with others" 呢句嘢近乎 tautology（同義反覆），冇任何分析性嘅內容。一個好嘅 Topic Sentence 應該係一個 sub-argument，而唔係一個描述性嘅觀察。其次，佢嘅 evidence 使用好表面——"a study by Smith (2020) found that 70%..." 呢種引用方式冇交代研究嘅方法、樣本規模、或者研究設計，Marker 會覺得你根本冇真正閱讀過原文。第三，佢嘅 analysis 近乎係冇嘅——成段嘅論證就係「有研究話點點點，所以社交媒體唔好」，中間完全冇解釋個因果機制係點運作。

QUT cite|write 嘅學術寫作指引 入面講得好清楚：一個有效嘅 body paragraph 必須包含 Point、Evidence、Explanation、同 Link 四個元素（即係 PEEL 結構），而以上呢段低分版本基本上只得 P 同 E，冇 E（explanation）同 L（link）。

咁高分版本應該點樣改寫？睇以下版本：

「A primary mechanism through which social media compromises adolescent psychological well-being is the intensification of upward social comparison processes. Unlike offline social environments, where comparative reference points are typically limited to immediate peer groups, social media platforms expose adolescents to a curated stream of idealised content — meticulously edited photographs, selective life milestones, and algorithmically amplified success narratives — that establishes unrealistic benchmarks for self-evaluation. Festinger's (1954) social comparison theory provides the foundational framework here: when individuals evaluate themselves against superior standards, the resulting perceived discrepancy triggers feelings of inadequacy and diminished self-worth. Empirical support for this mechanism is robust. Fardouly et al. (2015), in a controlled experimental study involving 112 female undergraduates, demonstrated that brief exposure to thin-ideal Instagram images produced significantly higher levels of negative mood and body dissatisfaction compared to control conditions. Longitudinal data reinforces these findings; Twenge et al. (2018), analysing a nationally representative sample of over 500,000 US adolescents, identified a sharp increase in depressive symptoms and suicide-related outcomes from 2010 onwards — a trajectory that closely tracks the proliferation of smartphone and social media adoption. This temporal correlation, while not sufficient to establish causality in isolation, aligns with the social comparison hypothesis and gains plausibility when triangulated with experimental evidence. The implication is significant: social media does not merely provide a neutral platform for self-expression; it actively reshapes the psychological landscape within which adolescent identity formation occurs, amplifying insecurities through mechanisms that offline social environments neither generate nor sustain at comparable intensity.」

呢段高分版本嘅差距喺邊？先睇 Topic Sentence——"A primary mechanism through which social media compromises adolescent psychological well-being is the intensification of upward social comparison processes." 呢句唔單止話俾讀者知你要討論咩，仲清楚說明咗呢個係一個 mechanism（機制），而唔係一個簡單嘅相關性。跟住你見到佢係有 explanation 嘅——解釋咗點解 online social comparison 同 offline 唔同（因為 curated content、algorithmic amplification），然後引用咗 Festinger 嘅經典理論嚟建立理論基礎。Evidence 方面，佢唔係淨係 quote 一個數字，而係交代咗研究設計（controlled experimental study、112 female undergraduates、nationally representative sample of over 500,000），令 Marker 知道你係真正理解呢啲文獻嘅。最後，佢有一個清晰嘅 concluding analysis，將成段嘅論證收束返去 thesis。

如果你寫緊一篇關乎 final year 成績嘅重要 essay，與其自己喺度摸索 PEEL 結構點用，不如考慮揾 essay代寫 嘅導師同你一齊 review 你嘅 body paragraph，逐段幫你分析邊度嘅論證鏈斷咗。

Body Paragraph 嘅第二組對比——處理反駁論點

寫 argumentative essay 最易出事嘅位，就係處理 counter-argument。好多同學一係完全唔處理（直接 ignore 相反觀點），一係處理得好敷衍（寫一句 "some people may disagree but I think they are wrong" 就當交咗功課）。喺大學程度嘅 essay 入面，counter-argument 嘅處理質素基本上可以直接決定你係攞 B 定係攞 A。

先睇低分版本嘅 counter-argument 處理：

「Some people argue that social media can actually help teenagers' mental health because it allows them to connect with friends and find support online. However, I believe the negative effects are more important. Even though social media can provide some benefits, the problems it causes are more serious. So overall, social media is bad for mental health.」

呢段嘅問題在於：佢根本冇真正 engage with 個 counter-argument。你只係 acknowledge 咗有相反意見存在，然後就用一句 "I believe the negative effects are more important" 輕輕帶過。Marker 睇到呢度嘅反應會係：「你憑咩話負面影響更重要？你有咩證據？」一個真正有效嘅 rebuttal 需要你做兩樣嘢：第一，你要公平準確咁呈現對方嘅論點（而唔係 straw man）；第二，你要用 evidence 同 logic 去說明點解你嘅立場喺權衡之後仍然成立。

舉個例，上述低分版本將 counter-argument 簡化成「社交媒體可以幫人 connect」，但實際上支持社交媒體正面影響嘅學術文獻係遠比呢個 nuanced 嘅——例如有研究指出，對於 LGBTQ+ 青少年或者居住喺偏遠地區嘅年輕人，online communities 係佢哋獲取 peer support 嘅主要渠道，呢啲 support 係 offline 環境提供唔到嘅。如果你唔去處理呢個層次嘅 counter-argument，你嘅 essay 就會顯得片面。

咁高分版本應該點做？睇以下寫法：

「It would be analytically incomplete to suggest that social media exerts exclusively negative psychological effects on adolescents. A substantial body of scholarship has documented the protective and restorative functions of online peer networks, particularly for adolescents who experience social marginalisation in offline contexts. For instance, Berger et al. (2022) found that LGBTQ+ adolescents who actively participated in moderated online support communities reported significantly lower levels of depressive symptoms and suicidal ideation compared to those without such access, largely attributable to identity validation and reduced social isolation. This finding carries considerable weight and challenges any unqualified condemnation of social media's psychological impact. However, three qualifications warrant consideration. First, the protective benefits identified in Berger et al.'s study were contingent upon participation in moderated, structured online communities — environments that constitute a minority of adolescents' actual social media usage, which predominantly occurs on algorithm-driven, engagement-optimised platforms. Second, the same connectivity that facilitates supportive interactions also enables pathological social dynamics, including cyberbullying and exclusionary group behaviours, with research by Kowalski et al. (2014) indicating that the psychological harm caused by cyber-victimisation typically exceeds that of traditional bullying due to its inescapability and permanence. Third, the critical distinction lies not in whether social media can produce positive outcomes, but in whether its net effect — accounting for both benefits and harms across the general adolescent population — is favourable. The epidemiological evidence reviewed in the preceding sections, particularly the population-level trend data, suggests it is not. This essay therefore does not dismiss the potential benefits of online peer support but argues that they are context-dependent, unevenly distributed, and ultimately insufficient to offset the broader structural harms generated by current platform architectures.」

呢段高分處理嘅精妙之處在於：佢先公平咁 acknowledge 咗對方嘅最強論點（LGBTQ+ 青少年嘅實證研究），然後通過三個層次 qualifications 去回應——第一係 contextual limitation（benefit 只喺特定條件下成立），第二係 countervailing mechanisms（同一個 connectivity 亦帶嚟 cyberbullying），第三係 net effect analysis（整體影響嘅權衡）。呢種處理方式顯示出你嘅 critical thinking 能力，亦係大學 essay 評分入面區分高分段同中分段嘅關鍵。

喺呢個位，有唔少同學會發覺自己嘅 essay 寫到 counter-argument 就卡住，因為 rebuttal 要寫得好，需要有一定嘅文獻閱讀量同分析能力。呢個時候，揾 essay代寫 嘅專業團隊幫你梳理文獻、組織 rebuttal 結構，可以令你嘅 essay 成個層次提升。一個寫得好嘅 counter-argument 唔單止唔會削弱你嘅立場，反而會令 Marker 覺得你係一個 mature thinker。

成日俾人忽略嘅位——段落之間嘅過渡

寫完幾組 body paragraph 嘅對比之後，我想特別講一個好多同學完全忽略嘅位：段落之間嘅 transitions。你可能覺得 transitions 只係加個 "Furthermore" 或者 "In addition" 就得，但其實大學高分 essay 對 transition 嘅要求遠高於此。

低分寫法嘅 transition 通常係咁：

段落 A 最後一句：「Therefore, social comparison on social media negatively affects teenage mental health.」
段落 B 第一句：「Another negative effect of social media is sleep disruption.」

呢種 transition 嘅問題在於：佢將兩個段落當做獨立嘅點去處理，而冇顯示出兩個點之間嘅邏輯關係。Marker 睇到會覺得你篇文嘅結構係 "list of points" 而唔係 "coherent argument"。一個高分 essay 嘅 internal logic 應該係：每一個新段落都係由上一個段落嘅 conclusion 自然延伸出嚟嘅。

高分版本嘅 transition 會係咁：

段落 A 最後一句：「This endogenous psychological mechanism, however, does not operate in isolation; its effects are compounded by behavioural patterns that social media platforms structurally incentivise, most notably the displacement of sleep.」
段落 B 第一句：「The relationship between social media usage and adolescent sleep deprivation has emerged as one of the most consistently replicated findings in digital health research over the past decade.」

你睇到分別嘛？高分版本嘅最後一句唔係淨係總結，而係為下一個段落鋪路——"its effects are compounded by..." 呢個 phrasing 話俾讀者知，你唔係跳去一個新話題，而係喺度 deepen 你嘅 analysis。呢個技巧喺 UNC Writing Center 嘅學術寫作資源 入面都有詳細講解，佢哋強調 transition 係要用嚟顯示 "the relationship between ideas"，而唔係純粹嘅順序標記。

呢個技巧表面睇落好似好簡單，但實際上需要你對成篇 essay 嘅 argument structure 有好清晰嘅掌握。如果你覺得自己嘅 essay 段落之間嘅 connection 唔夠 tight，與其夾硬加 transition words，不如先重新審視你嘅 essay outline。有需要嘅時候，揾 essay代寫 嘅專業導師幫你 re-structure 一次成篇文嘅 flow，效果會比你自己喺度死磨好得多。

Conclusion 嘅低分同高分寫法

最後嚟到 Conclusion，呢個係最多同學「臨尾香」嘅位。好多同學寫到 Conclusion 嘅時候已經好攰，求其將 Introduction 嘅嘢 rephrase 一次就算。結果成篇文前面寫得好好地，但 Conclusion 一嘢將成個 impression 拉低晒。

先睇低分版本：

「In conclusion, this essay has discussed the impact of social media on adolescent mental health. It has shown that social media has many negative effects such as social comparison, sleep problems, and distraction. Although there are some positive aspects, the negative effects are more significant. Therefore, teenagers should be careful about using social media and parents should monitor their children's online activities.」

呢段 Conclusion 有幾個典型問題。第一，純粹 summarise 而冇 synthesize——"this essay has discussed" 同 "it has shown that" 呢啲 phrasing 只係將前文重講一次，冇將唔同嘅論點整合成一個更高層次嘅 insight。第二，提出咗一個好 vague 嘅 recommendation——"teenagers should be careful" 同 "parents should monitor" 呢類建議太過 general，冇任何具體性或者政策 implications。第三，成段冇顯示出你篇文嘅 broader significance——讀完你篇 essay，讀者應該明白「所以呢？」，而呢段 Conclusion 答唔到呢個問題。

咁高分嘅 Conclusion 要點寫？

「This essay has argued that social media's net psychological impact on adolescents is predominantly negative, advancing this claim through an examination of three interconnected mechanisms: the intensification of upward social comparison, the structural displacement of sleep, and the fragmentation of sustained attention. The significance of this analysis extends beyond an academic exercise in weighing evidence. If the mechanisms identified here are indeed fundamental to how social media platforms interact with adolescent developmental psychology, then current regulatory and educational approaches — which predominantly focus on digital literacy and screen-time limits — may be insufficient. Platform architectures designed to maximise engagement through algorithmic curation are not value-neutral conduits; they actively shape the psychological conditions under which adolescent identity formation occurs. This recognition carries implications for multiple stakeholders. For educators, it suggests that digital literacy curricula should move beyond cautionary messaging to incorporate critical media psychology and algorithmic awareness. For policymakers, it underscores the need for platform transparency mandates — particularly regarding algorithmic recommendation systems targeting minor users — that go beyond the self-regulatory frameworks currently favoured by industry. For researchers, it highlights a pressing need for longitudinal, platform-independent studies capable of disentangling the specific causal pathways proposed here from the broader matrix of adolescent developmental challenges. The question, ultimately, is not whether to disconnect adolescents from digital social networks — an unrealistic and arguably undesirable proposition — but how to redesign these digital environments in ways that preserve their connective potential while mitigating the psychological harms identified in this analysis.」

呢段 Conclusion 嘅高明之處在於：佢唔係純粹 summarise，而係 synthesize——將 social comparison、sleep disruption、attention fragmentation 三個 mechanisms 整合成一個統一嘅 analytical framework。跟住佢做咗三件高分 Conclusion 必須做嘅嘢：講 broader implications（對 educators、policymakers、researchers 嘅影響）、acknowledge complexity（"not whether to disconnect... but how to redesign"）、同埋用一個 thought-provoking 嘅 closing 去收尾。成段嘅 tone 係 forward-looking 而唔係 backward-looking，令 Marker 覺得你唔單止理解咗個議題，仲有能力將佢延伸去更大嘅討論脈絡。

如果你覺得自己嘅 Conclusion 永遠都係寫到好似低分版本咁，可以考慮參考 大學 Essay 寫作技巧 入面關於 conclusion writing 嘅詳細指導。又或者，直接揾 essay代寫 團隊幫你檢查成篇文嘅 conclusion，確保佢可以同前面嘅 argument 形成一個完整嘅閉環。

你可能仲想問

講到呢度，你可能心入面仲有幾個疑問。以下係我嘅學生最常問嘅幾樣嘢，我喺度一次過答埋。

• 文章通常要寫幾多字先夠？ 呢個真係視乎你間大學同個 course 嘅 requirement。一般 undergraduate essay 係 1500 到 3000 字，但重點唔係字數，而係你有冇喺有限字數之內建立到一個完整嘅 argument。見過有同學寫 3000 字但全篇都係 descriptive writing，一樣攞 C。亦都見過有同學寫 1200 字但 argument 好 tight，攞到 B+。所以與其擔心字數，不如擔心你嘅論證質素。
• 我可唔可以用 ChatGPT 幫手寫 essay？ 技術上你可以，但實際上大學而家嘅 plagiarism detection 系統（包括 Turnitin）已經進化到可以 detect AI-generated content。而且 AI 寫出嚟嘅 essay 通常有個好明顯嘅問題：好睇但冇深度。佢會 generate 到好多 "on the one hand... on the other hand..." 嘅嘢，但永遠唔會有一個清晰嘅 thesis。如果你真係想用 AI 輔助，建議只係用嚟 brainstorm outline 或者 check grammar，千祈唔好直接交 AI 寫嘅嘢。
• 如果 essay 趕 deadline 點算？ 老實講，最好嘅方法係唔好俾自己陷入呢個 situation。但如果你真係已經趕到冇得再趕，首先要做嘅係 stop researching——你已經冇時間再睇新文獻。攞返你手上嘅資料，寫一個最清晰嘅 outline，然後用 bullet points 去 draft 每個 paragraph 嘅 main points，最後先 expand 成完整句子。呢個方法可以保證你喺有限時間內起碼 produce 到一個 coherent 嘅 essay。不過當然，如果你係喺 deadline 前 24 小時先發現自己完全寫唔切，又或者篇文佔你 final grade 好重，咁揾專業團隊幫手會係比較穩陣嘅選擇。
• 點樣知道自己篇 essay 咩 level？ 一個好簡單嘅 self-check 方法：睇返你每一個 body paragraph，問自己三個問題——呢段嘅 topic sentence 係咪一個 arguable claim？呢段嘅 evidence 有冇交代研究設計同 sample size？呢段嘅 conclusion sentence 有冇 link 返去你嘅 thesis？如果任何一段答唔到是但一條，你篇 essay 嘅上限大概就係 B。
• 大學 essay 同中學 essay 最大分別係咩？ 中學 essay 主要睇你有冇理解到課堂教嘅內容，大學 essay 係睇你有冇能力建立自己嘅論點。換句話講，中學係 "show me you've learned"，大學係 "show me you can think"。所以大學 essay 最忌就係 pure summary——你每寫一句都要問自己：呢句係 in service of 我個 argument 定係純粹 regurgitate 資料？
• Turnitin similarity 幾多先算 safe？ 大部分香港大學嘅 acceptable threshold 係 15-20%，但呢個數字只係 guidance，唔係 absolute rule。更加緊要嘅係你啲 matched sources 嘅性質——如果全部都係 properly cited 嘅 academic sources，就算 20% 都未必有問題。但如果有一大段 matched 咗 websites 或者其他 student papers，就算 10% 都可以 trigger investigation。所以我成日同學生講，與其自己喺度估個 similarity report 安唔安全，不如一開始就確保你嘅 paraphrasing 同 citation 係到位嘅。
