1. Overview of the Mock Unit Test | 模拟单元测试概览
The mock paper is designed to mirror the format of Paper 1 (Knowledge, Reality, and Self) but focuses solely on Knowledge and Reality. It is divided into three sections: Section A contains short-answer definition and explanation questions worth 15 marks; Section B presents stimulus-based questions requiring analysis of philosophical scenarios, worth 25 marks; Section C is a single essay question chosen from two options, worth 20 marks. The total mark is 60, with a recommended time of 75 minutes. Understanding this structure is the first step to managing your time effectively.
这份模拟卷按照 Paper 1（知识、现实与自我）的格式设计，但仅聚焦知识与现实单元。试卷分为三个部分：A 部分为简答型定义与解释题，共 15 分；B 部分是基于情境的分析题，需要围绕哲学场景展开讨论，共 25 分；C 部分是从两道中任选一题的论文题，共 20 分。满分 60 分，建议用时 75 分钟。了解这一结构是有效分配时间的第一步。
2. Section A: Defining Key Concepts | A 部分：定义关键概念
Question 1 typically asks: 'Define knowledge as justified true belief.' A strong answer must state that, according to Plato, knowledge is belief that is both true and supported by evidence or reasons (justification). Avoid simply writing 'JTB' – you need to unpack each element. For full marks, add that the belief must match reality (truth) and the knower must have good grounds for holding it (justification). An example, such as 'knowing that Paris is the capital of France because you have verified it with reliable sources,' can illustrate the definition.
Question 1 通常要求：“定义知识为确证的真信念”。一个优质答案必须指出，柏拉图认为知识是既真实又有证据或理由（确证）支持的信念。不要只写“JTB”——你需要逐一解释每个要素。要想拿满分，还要补充说明信念必须符合现实（真），且认知者必须拥有持有该信念的充分依据（确证）。举一个例子，比如“知道巴黎是法国的首都，因为你已通过可靠来源核实”，可以很好地阐明这一定义。
3. Unpacking 'Justified True Belief' | 解析“确证真信念”
In a 5-mark explanation question, you might be asked to elaborate on why justification is necessary. Your response should clarify that without justification, a true belief could be a lucky guess, which we would not count as knowledge. For instance, if someone predicts that a coin will land heads just by guessing, and it does, they held a true belief but did not know it would happen. Use the formula K = J + T + B only as a shorthand, but always describe the relationship: justification links the belief to truth in a non-accidental way.
在一道 5 分的解释题中，你可能被要求详细说明为何确证是必要的。你的答案应阐明，若没有确证，真信念可能只是侥幸猜对，而我们不会将之视为知识。例如，某人仅凭猜测预测硬币落地为正面，结果果然如此，他持有真信念，但并非真正知道硬币会正面朝上。可以把公式 K = J + T + B 当作速记符号，但一定要描述其中的关系：确证以非偶然的方式将信念与真相连。
4. Evaluating Gettier Cases | 评价盖梯尔案例
Many students lose marks when asked to explain how Gettier cases challenge the JTB definition. You must first outline a classic Gettier-style scenario, such as Smith believing 'the person who will get the job has ten coins in their pocket' based on strong evidence, when in fact Smith himself gets the job and unknowingly has ten coins in his pocket. The belief is true and justified, yet we hesitate to call it knowledge. Then you must explain why: the justification is not appropriately connected to the truth in the way knowledge requires. This demonstrates that the traditional tripartite definition may be insufficient.
当被要求解释盖梯尔案例如何挑战 JTB 定义时，很多同学会失分。你必须先简要描述一个经典的盖梯尔式情境，例如：史密斯凭借有力证据相信“即将得到工作的人口袋里有十枚硬币”，结果他自己得到了工作且凑巧口袋里也有十枚硬币，尽管他事先并不知道。这个信念既真又确证，但我们却不愿称之为知识。接着你必须解释原因：这里的“确证”并未以知识所需的方式与“真”恰当相连。这表明传统的三元定义可能是不够的。
5. Section B: Comparing Empiricism and Rationalism | B 部分：比较经验论与唯理论
A common stimulus question presents two short passages – one arguing that all ideas come from sensory experience (empiricism), the other claiming that certain truths, such as mathematical principles, are known through reason alone (rationalism). You are asked to compare their accounts of the origin of knowledge. A full-mark response identifies that empiricists, like Locke, maintain the mind is a tabula rasa at birth, while rationalists, like Descartes, argue for innate ideas. Crucially, you must also evaluate a strength and a limitation of each view, using examples such as concept empiricism's difficulty with abstract categories (e.g., justice) and rationalism's reliance on a priori justification.
常见的材料题会给出两段短文——一段主张所有观念都来自感觉经验（经验论），另一段则宣称某些真理，如数学原理，仅凭理性即可知晓（唯理论）。题目要求比较二者关于知识起源的论述。满分作答应指出，经验论者如洛克认为人心初生时如同一块白板，而唯理论者如笛卡尔则主张存在天赋观念。关键还在于，你需要借助例子分别评价两者的一种优势与一种局限，比如概念经验论难以解释抽象范畴（如“正义”），而唯理论则过度依赖先验确证。
6. Analysing the Brain-in-a-Vat Scenario | 分析缸中之脑情景
This sceptical thought experiment asks: 'If you were a brain in a vat connected to a supercomputer generating all your experiences, could you know that you are not?' Your analysis must first clarify the challenge to empirical knowledge: if all sensory input can be simulated, then our perceptual beliefs about the external world could be entirely false. A strong answer then offers a philosophical response, such as a reliablist rejection (we form beliefs through reliable processes, even in a simulation) or an inference-to-the-best-explanation argument, keeping in mind that the question usually does not require you to resolve scepticism, but to show understanding of the problem and its implications.
这个怀疑论思想实验问道：“如果你是一个泡在缸中、连上超级计算机的大脑，计算机为你生成一切体验，你能否知道自己并非如此？”你的分析首先要澄清它对经验知识的挑战：如果所有感觉输入都能被模拟，那么我们关于外部世界的知觉信念就完全可能为假。一份优秀答案随后会给出一种哲学回应，比如可靠主义的拒斥（即便身处模拟，我们依然通过可靠过程形成信念）或最佳解释推论，但要记住，题目通常无需你彻底解决怀疑论，而是展示对问题及其推论的理解。
7. Tackling Realism about Universals | 处理共相实在论
In the Reality section, you might be asked to explain Platonic Realism. Begin by stating that it is the view that universals (e.g., 'redness' or 'triangularity') exist independently of particular objects and of the mind. Use an example: many individual red things share the same property of redness, which realists take to be a real, non-physical entity existing in a realm of Forms. Contrast this with nominalism, which claims only particulars exist and universals are merely names we invent. A comparison table is not required in the exam, but mentally mapping 'Problematic universals' and 'Ockham's razor' will help you structure a balanced argument.
在“现实”单元，你可能会被要求解释柏拉图式实在论。首先要说明，该观点主张共相（如“红性”或“三角性”）独立于个别事物和心灵而存在。举个例子：许多个别的红色物体共享着相同的红之属性，实在论者认为这一属性是真实存在的、非物理的实体，存于理型界。将之与唯名论对比：唯名论主张只有个别事物存在，共相不过是人类发明的名称。考试中不需要画表格，但在心中对照“共相难题”和“奥卡姆剃刀”将有助于你组织平衡的论证。
8. Idealist Critiques of Materialism | 唯心论对唯物论的批评
A Section B question may present a Berkeleyan idealist argument: 'To be is to be perceived.' Your job is to reconstruct the critique of material substance. Explain that Berkeley argues matter, as an unperceiving substance, is an incoherent notion because we can never conceive of something existing without it being an object of perception. Therefore, only minds and ideas exist. In your evaluation, bring in the objection from the persistence of objects (the table still exists when no one is in the room) and consider Berkeley's appeal to God as the permanent perceiver. Demonstrate that you can see both the internal logic and the common-sense counter-arguments.
B 部分的一道题目可能给出贝克莱的唯心论论证：“存在即是被感知。”你的任务是重构对物质实体的批评。要解释贝克莱是如何论证物质作为不被感知的实体这一概念自相矛盾的，因为我们永远无法设想某物存在却不同时为一个知觉对象。因此，唯有心灵与观念存在。在评价部分，要引入“物体持续存在”的反驳（当无人在房间时桌子依然存在），并思考贝克莱借助上帝作为永恒感知者的回应。展现你能同时看到其内在逻辑与常识层面的反驳。
9. Section C: Essay on Primary and Secondary Qualities | C 部分：关于第一性质与第二性质的论文
The essay question, which carries 20 marks, might ask: 'Critically evaluate Locke's distinction between primary and secondary qualities.' Your introduction should state that primary qualities (e.g., solidity, extension, motion) are inseparable from the object and resemble our ideas of them, while secondary qualities (e.g., colour, taste, sound) are powers to produce sensations in us that do not resemble the object itself. In the body, develop arguments for and against: for instance, the scientific success of this distinction in mechanism, but also Berkeley's criticism that primary qualities are just as mind-dependent because extension and shape are perceived through senses. Conclude by weighing the philosophical significance. Always link your paragraphs and use evaluative phrases such as 'this is convincing because...' or 'however, this overlooks...' to reach the top mark band.
这道 20 分的论文题可能会这样出：“批判性评估洛克关于第一性质与第二性质的区分。”你的引言应说明，第一性质（如体积、广延、运动）与物体不可分且与我们的观念相似，而第二性质（如颜色、味道、声音）只是在人心中产生感觉的能力，这些感觉本身并不与物体相似。正文中要展开支持和反对的论证：例如，这一区分在机械科学中的成功应用，但也需讨论贝克莱的批评——第一性质也同样依赖于心灵，因为广延和形状也是通过感知获得的。结尾要权衡其哲学重要性。务必连接各个段落，并使用“这一论述令人信服，因为……”或“然而，这忽视了……”等评价性短语，才能跻身最高分档。
10. Common Mistakes and Examiner Advice | 常见错误与考官建议
One frequent error is merely describing a theory without evaluating it. In the CAIE mark scheme, half the marks in longer questions are for analysis and evaluation. Another pitfall is using technical terms loosely – for example, confusing 'a priori' with 'innate' or using 'valid' interchangeably with 'true'. Remember, an argument is valid if the conclusion follows from the premises; it does not have to be true. Finally, manage your time: do not spend 40 minutes on the 15-mark Section A. Allocate time proportionally and keep a watchful eye on the clock. Practise writing quick plans before each essay to ensure a logical flow.
一个常见错误是仅仅描述理论而不进行评价。在 CAIE 评分方案中，较长题目有一半得分都取决于分析与评价。另一个陷阱是松泛地使用术语——例如，混淆“先验”与“天赋”，或将“有效”等同于“真”。请记住，一个论证有效当且仅当结论能从前提中推出，并不要求前提为真。最后，把控好时间：不要用 40 分钟去答 15 分的 A 部分。按分值比例分配时间，时刻留意钟表。在每篇论文动笔前练习快速列出提纲，以保证行文逻辑连贯。
