1. Contract Formation: Offer vs Invitation to Treat | 合同成立：要约与要约邀请
An offer is a definite promise to be bound on specific terms, whereas an invitation to treat is merely an invitation to make an offer. The classic authority is Pharmaceutical Society of Great Britain v Boots Cash Chemists (1953), where goods on display were held to be invitations to treat, not offers. Understanding this distinction is fundamental because it determines who makes the legally operative offer.
要约是一项受特定条款约束的明确承诺，而要约邀请仅仅是邀请对方发出要约。经典的权威案例是 Pharmaceutical Society of Great Britain v Boots Cash Chemists (1953) 案，该案判定展示的商品属于要约邀请，而非要约。理解这一区别至关重要，因为它决定了谁作出有法律效力的要约。
Students often mischaracterise advertisements as offers. The general rule is that advertisements are invitations to treat, as in Partridge v Crittenden (1968). However, an advertisement may constitute a unilateral offer if it shows a clear intention to be bound, as seen in Carlill v Carbolic Smoke Ball Co (1893) where the company deposited money to show sincerity. A common mistake is failing to identify the exception: when an advertisement prescribes a specific act and promises something in return, it becomes an offer.
学生经常将广告错误地归为要约。一般规则是广告属于要约邀请，如 Partridge v Crittenden (1968) 案所示。但是，如果广告表明明确的受约束意图，则可能构成单方要约，例如在 Carlill v Carbolic Smoke Ball Co (1893) 案中，公司存入资金以表明诚意。常见的错误是未能识别这一例外：当广告规定特定行为并承诺回报时，它就成为要约。
Another frequent error is treating a price list or catalogue as an offer; these are invitations to treat. Similarly, a machine that dispenses goods is normally an offer when the customer selects the product, not an invitation. Examiners reward precise terminology, so be sure to label the parties correctly as offeror and offeree at each stage.
另一个常见错误是将价目表或产品目录视为要约；这些均属要约邀请。同样，自动售货机通常在顾客选择商品时构成要约，而非要约邀请。考官看重术语的准确性，因此务必在每个阶段正确标定要约人和受要约人。
2. Consideration and Privity | 对价与合同相对性原则
Consideration must be sufficient but need not be adequate. The key rule is that past consideration is not good consideration (Re McArdle (1951)), unless the act was done at the promisor’s request and payment was implied (Lampleigh v Brathwait (1615)). A common mistake is applying the past consideration rule too rigidly without checking for an implied understanding of reward.
对价必须充足但不必相当。关键规则是过去的对价不是有效的对价（Re McArdle (1951)），除非该行为是应允诺人要求而为，且隐含支付报酬的谅解（Lampleigh v Brathwait (1615)）。一个常见错误是过于僵硬地适用过去对价规则，而未检查是否存在默示的报酬谅解。
Performance of an existing contractual duty owed to the promisor does not normally amount to consideration, but Williams v Roffey Bros (1990) created a practical benefit exception. Where the promisor obtains a practical benefit and there is no duress, the promise to pay extra can be enforced. Examiners frequently test whether students confuse this with the rule in Foakes v Beer (1884) regarding part payment of a debt, where a practical benefit does not discharge the whole debt. Know the distinction.
履行对允诺人负有的现有合同义务通常不构成对价，但 Williams v Roffey Bros (1990) 案创设了一个“实际利益”例外。当允诺人获得实际利益且无胁迫时，额外支付的承诺可以强制执行。考官经常测试学生是否将此与 Foakes v Beer (1884) 案的部分债务清偿规则混淆，在该规则下，实际利益并不能免除全部债务。请掌握这一区别。
Privity of contract means that only parties to a contract can enforce its terms (Tweddle v Atkinson (1861)). However, the Contracts (Rights of Third Parties) Act 1999 allows a third party to enforce a term if the contract expressly provides so or if the term purports to confer a benefit on them. A typical error is forgetting to mention the 1999 Act when discussing third-party rights, leading to an incomplete analysis.
合同相对性意味着只有合同当事人才能执行合同条款（Tweddle v Atkinson (1861)）。然而，《1999年合同（第三人权利）法》允许第三人在合同明示规定或条款旨在赋予其利益时执行该条款。一个典型错误是在讨论第三人权利时忽略提及该1999年法案，导致分析不完整。
3. Contractual Terms: Conditions, Warranties and Innominate Terms | 合同条款：条件条款、保证条款与中间条款
The classification of terms as conditions, warranties, or innominate terms determines the remedies available for breach. A condition goes to the root of the contract, breach of which allows the innocent party to terminate and claim damages. A warranty is a lesser term, where the remedy is damages only. Examiners look for precise case law, such as Poussard v Spiers (1876) for a condition and Bettini v Gye (1876) for a warranty.
将条款分类为条件条款、保证条款或中间条款，决定了违约时可获得的救济。条件条款触及合同根基，违反它可使无过错方有权终止合同并索赔损害赔偿。保证条款是次要条款，救济仅为损害赔偿。考官希望看到精准的判例，例如 Poussard v Spiers (1876) 案中的条件条款，以及 Bettini v Gye (1876) 案中的保证条款。
Innominate terms, introduced by Hong Kong Fir Shipping Co Ltd v Kawasaki Kisen Kaisha Ltd (1962), focus on the consequences of the breach. If the breach deprives the innocent party of substantially the whole benefit of the contract, the term is treated as a condition; otherwise, only damages are available. A common mistake is automatically treating intermediary terms as warranties. Always analyse the seriousness of the breach’s effect.
由 Hong Kong Fir Shipping Co Ltd v Kawasaki Kisen Kaisha Ltd (1962) 案引入的中间条款，关注的是违约的后果。如果违约实质上剥夺了无过错方根据合同预期获得的全部利益，该条款就按条件条款处理；否则仅能得到损害赔偿。常见错误是自动将中间条款当作保证条款。务必分析违约后果的严重性。
Students also stumble when integrating the Unfair Contract Terms Act 1977 and the Consumer Rights Act 2015 on exclusion clauses. Remember that these statutes impose controls on limitation and exclusion clauses, especially regarding personal injury and fairness. This is often tested alongside contractual terms.
学生在结合涉及免责条款的《1977年不公平合同条款法》和《2015年消费者权利法》时也容易出现失误。请记住，这些法律对责任限制与排除条款施加了控制，尤其涉及人身伤害和公平性方面。这一点经常与合同条款一起考核。
4. Misrepresentation: Categories and Remedies | 误导性陈述：分类与救济
A misrepresentation is a false statement of fact that induces a party to enter into a contract. The three categories are fraudulent, negligent, and innocent misrepresentation. A frequent high-frequency topic is the difference in remedies. For fraudulent misrepresentation (tort of deceit), the claimant can claim rescission and damages in the tort of deceit, including all direct losses.
误导性陈述是指诱使一方订立合同的虚假事实陈述。三种类别是欺诈性、过失性和无意的误导性陈述。一个常考的重点是救济措施的差异。对于欺诈性误导性陈述（欺诈侵权），索赔人可以要求撤销合同并依据欺诈侵权索赔损害赔偿，包括所有直接损失。
Under s.2(1) of the Misrepresentation Act 1967, damages can be awarded for negligent misrepresentation as if the statement were made fraudulently, unless the representor proves they had reasonable grounds to believe the statement was true. This reverse burden of proof is a classic exam trap: students often forget that the burden shifts to the defendant. For innocent misrepresentation, the court has discretion under s.2(2) to award damages in lieu of rescission.
根据《1967年误导陈述法》第2(1)条，对于过失性误导性陈述，可以像作出欺诈性陈述一样判予损害赔偿，除非陈述人能证明其有合理理由相信该陈述是真的。这一倒置的举证责任是典型的考试陷阱：学生常常忘记举证责任转移至被告。对于无意的误导性陈述，法院根据第2(2)条有酌情权以损害赔偿代替撤销合同。
A common error is failing to distinguish between a statement of fact and a statement of opinion or future intention. Generally, opinions are not misrepresentations unless they are not honestly held or imply facts. Similarly, silence does not amount to misrepresentation unless there is a duty of disclosure, as in contracts of utmost good faith.
常见错误是未能区分事实陈述与意见或未来意图的陈述。一般而言，意见不构成误导性陈述，除非该意见并非真诚持有或隐含了事实。同样，沉默不构成误导性陈述，除非存在披露义务，例如在最高诚信合同中。
5. Negligence: Duty of Care – The Caparo Test | 疏忽：注意义务——卡帕罗测试
To establish negligence, the claimant must prove a duty of care was owed. The current test, laid down in Caparo Industries plc v Dickman (1990), requires three elements: (1) the damage was reasonably foreseeable; (2) there was proximity between the parties; and (3) it is fair, just and reasonable to impose a duty. Students often recite the test but fail to apply each element to the facts, losing AO2 marks.
要证明疏忽，索赔人必须证明存在注意义务。当前由 Caparo Industries plc v Dickman (1990) 案确立的测试要求三个要素：(1) 损害是合理可预见的；(2) 双方之间存在近邻关系；(3) 施加义务是公平、公正且合理的。学生常会背诵该测试，却未能将每个要素应用于案件事实，从而丢失AO2分数。
In established duty situations, such as doctor–patient or manufacturer–consumer (Donoghue v Stevenson (1932)), the Caparo test is normally satisfied. Difficult cases arise with omissions and public bodies. For example, in Hill v Chief Constable of West Yorkshire (1989), no duty was imposed on the police to protect a potential victim due to policy reasons. Examiners often ask about exceptions based on public policy, so be prepared to explain the rationale.
在已确立的义务情形中，如医生—病人或制造商—消费者（Donoghue v Stevenson (1932)），卡帕罗测试通常得到满足。棘手的情形出现在不作为和公共机构方面。例如，在 Hill v Chief Constable of West Yorkshire (1989) 案中，基于政策原因，警方未被施加保护潜在受害者的义务。考官常就基于公共政策的例外情况提问，故应准备解释其理据。
A common error is treating proximity purely as physical closeness; legal proximity also considers the relationship. Moreover, the ‘fair, just and reasonable’ limb is where policy considerations such as floodgates, defensive practices, and public resources are weighed. Ignoring these can lead to an unsound conclusion.
常见错误是把近邻关系单纯视为物理上的接近；法律上的近邻关系还须考虑关系性质。此外，“公平、公正且合理”这一环节会权衡政策考量，如诉讼洪水、防御性操作和公共资源。忽视这些可能导致不合理的结论。
6. Breach of Duty and Standard of Care | 违反义务与注意标准
Once a duty is established, the standard of care is assessed objectively: what would the reasonable person have done in the circumstances? The classic statement is in Blyth v Birmingham Waterworks Co (1856). The standard is adjusted for certain characteristics: children are judged by the standard of a reasonable child of that age (Mullin v Richards (1998)), and professionals by the standard of the ordinary skilled professional following the Bolam test (Bolam v Friern Hospital Management Committee (1957)), as modified by Bolitho (1997).
一旦确立注意义务，注意标准即客观评定：一个合理之人在同样情形下会如何做？经典表述见于 Blyth v Birmingham Waterworks Co (1856) 案。标准因某些特征而调整：儿童按该年龄的合理儿童标准判断（Mullin v Richards (1998)），专业人员则按 Bolam 测试下拥有普通技能的专业人员的标准（Bolam v Friern Hospital Management Committee (1957)），并经 Bolitho (1997) 案修正。
Risk factors that influence the standard include the likelihood of harm, the seriousness of potential injury, the cost of taking precautions, and the social value of the defendant’s activity (Watt v Hertfordshire County Council (1954)). A common mistake is to ignore these balancing factors in a structured response. Always show how the reasonable person weighs them—this is essential for top marks.
影响注意标准的风险因素包括损害发生的可能性、潜在伤害的严重性、采取预防措施的成本以及被告活动所具有的社会价值（Watt v Hertfordshire County Council (1954)）。常见错误是在结构化回答中忽略这些平衡因素。务必展示合理之人如何权衡它们——这对获得高分至关重要。
Students also confuse the professional standard with perfection; the Bolam test merely requires that the professional acted in accordance with a responsible body of professional opinion. Failing to mention Bolitho‘s requirement that the body’s opinion must be logical and defensible is another exam pitfall.
学生还容易混淆专业标准与完美标准；Bolam 测试仅要求专业人员按照一个负责任的专业团体之意见行事。未能提及 Bolitho 案要求该团体的意见必须合乎逻辑且具有可辩解性，则是另一个考试陷阱。
7. Causation and Remoteness of Damage | 因果关系与损害的遥远性
Causation in fact uses the ‘but for’ test: but for the defendant’s breach, would the claimant have suffered the harm? (Barnett v Chelsea and Kensington Hospital Management Committee (1969)). Where there are multiple causes, the defendant’s breach must make a material contribution (Bonnington Castings v Wardlaw (1956)). A high-frequency exam scenario involves a defendant arguing that the harm would have occurred anyway, so students must fully apply the but for test.
事实因果关系适用“若非”测试：若非被告的过失，索赔人会遭受损害吗？（Barnett v Chelsea and Kensington Hospital Management Committee (1969)）。当存在多个原因时，被告的过失必须作出实质性贡献（Bonnington Castings v Wardlaw (1956)）。考试高频情景是被告辩称损害无论如何都会发生，因此学生必须充分应用若非测试。
Legal causation considers whether the damage is too remote. The test from Overseas Tankship (UK) Ltd v Morts Dock and Engineering Co Ltd (The Wagon Mound (No 1)) (1961) is that the damage must have been foreseeable in kind. The eggshell skull rule (Smith v Leech Brain & Co (1962)) applies to extent of harm, so take your victim as you find him. A typical error is using the thin skull rule before establishing that the type of harm was foreseeable.
法律因果关系考虑损害是否过于遥远。来自 Overseas Tankship (UK) Ltd v Morts Dock and Engineering Co Ltd (The Wagon Mound (No 1)) (1961) 的测试是，损害在类型上必须是可预见的。蛋壳头骨规则（Smith v Leech Brain & Co (1962)）适用于损害的程度，即按受害者原有状况接受之。常见的错误是先使用薄头骨规则，而未先确立损害的类型是可预见的。
Novus actus interveniens must be a truly independent intervening act that breaks the chain of causation. Acts of the claimant, third parties, and natural events can be novus actus if unforeseeable or highly unreasonable. Students sometimes mislabel any intervening event as novus actus without evaluating its foreseeability and reasonableness.
新介入行为必须是真正独立的、打断因果链条的介入行为。索赔人自身行为、第三人行为和自然事件如果是不可预见或极其不合理的，可构成新介入行为。学生有时会将任何介入事件都错误地标为新介入行为，而不评估其可预见性与合理性。
8. Occupiers’ Liability: Visitors and Trespassers | 占有人责任：来访者与侵入者
Occupiers’ liability is governed by two statutes: the Occupiers’ Liability Act 1957 for lawful visitors and the Occupiers’ Liability Act 1984 for trespassers. Under the 1957 Act, an occupier owes a common duty of care to see that visitors will be reasonably safe in using the premises for the purposes for which they are permitted to be there. Children must be expected to be less careful, and visitors exercising a calling are expected to guard against special risks (Roles v Nathan (1963)).
占有人责任受两部成文法管辖：《1957年占有人责任法》针对合法来访者，《1984年占有人责任法》针对侵入者。根据1957年法，占有人负有一般注意义务，确保来访者在其被允许进入的目的范围内使用场所时合理地安全。必须预见到儿童会较少谨慎，而从事特定职业的来访者被期待防范特殊风险（Roles v Nathan (1963)）。
Under the 1984 Act, a duty is owed to trespassers only if three conditions are satisfied: (1) the occupier is aware of the danger or has reasonable grounds to believe it exists; (2) the occupier knows or has reasonable grounds to believe that a trespasser is in the vicinity of the danger; and (3) the risk is one against which, in all the circumstances, the occupier may reasonably be expected to offer some protection. A serious mistake is assuming that a duty is automatically owed to all trespassers; the Act requires these preconditions.
根据1984年法，仅在满足三项条件时才对侵入者负注意义务：(1) 占有人知晓危险或有合理理由相信其存在；(2) 占有人知道或有合理理由相信侵入者处于危险附近；(3) 该风险在所有情况下是合理期待占有人提供某种保护的风险。一个严重错误是假定对所有侵入者自动负有义务；该法要求满足这些前提条件。
Additionally, warnings and defences such as consent (volenti) apply. For the 1984 Act, the duty is less onerous: to take such care as is reasonable in all the circumstances to see that the trespasser does not suffer injury on the premises. Students often forget to distinguish the different duty standards and apply the 1957 Act to trespassers.
此外，警告和抗辩（如自愿同意）也适用。对于1984年法，义务负担较轻：在所有情形下采取合理的谨慎，确保侵入者不会在场所内遭受人身伤害。学生常忘记区分不同的义务标准，并将1957年法适用于侵入者。
