本速查手册将剑桥国际 AS & A Level 社会学 (9699) 的核心思想提炼为简洁的理论“公式”与方法论原则。每一条目都旨在帮助 12 年级学生记忆关键概念、理解社会力量之间的关系，并在考试中运用社会学推理。
1. Functionalism: Society as a System | 功能主义：社会系统
Functionalism views society as a complex system whose parts—institutions, roles, norms—work together to maintain equilibrium. This perspective is often captured by a set of theoretical ‘equations’ linking social integration, value consensus and stability.
功能主义把社会视为一个复杂系统，其各部分——制度、角色、规范——协同运作以维持均衡。这一视角常常用一组理论“方程”来表达，将社会整合、价值共识与稳定联系在一起。
Core formula: Social stability ∝ Value consensus × Social integration
Durkheim argued that shared norms and strong social bonds reduce anomie. The more individuals feel connected to a collective conscience, the lower the risk of social breakdown. Parsons later added that any social system must fulfil four functional prerequisites: adaptation, goal attainment, integration and latency (AGIL).
涂尔干认为，共享的规范与紧密的社会纽带会减少失范。个体越是感受到与集体良知的联系，社会崩溃的风险就越低。帕森斯后来补充指出，任何社会系统都必须满足四项功能前提：适应、目标达成、整合与模式的维持（AGIL）。
Theorem 1 (Durkheim): Social integration ↓ → Egoistic suicide ↑
Insufficient integration leaves individuals without sufficient moral regulation, making them more vulnerable to despair.
整合不足让个体缺乏足够的道德规约，使其更容易陷入绝望。
Theorem 2 (Merton): Strain = Cultural goals – Legitimate means
When society emphasises success goals but blocks access to legitimate means, strain arises, leading to deviance (innovation, ritualism, retreatism, rebellion).
当社会强调成功目标却阻碍了合法手段的获取时，便会产生紧张，导致越轨行为（创新、仪式主义、退却主义、反抗）。
2. Marxism: Conflict and Class Struggle | 马克思主义：冲突与阶级斗争
Marxist sociology interprets society through the lens of class conflict and economic exploitation. The central ‘equation’ of Marxism posits that the economic base determines the superstructure, but class consciousness can catalyse revolutionary change.
马克思主义社会学透过阶级冲突和经济剥削的棱镜来解读社会。其核心“方程”设定，经济基础决定上层建筑，但阶级意识能够催化革命性变革。
Base → Superstructure: Economy shapes law, politics, education, religion
For Marx, the mode of production forms the real foundation upon which a legal and political superstructure rises. The ruling class controls both the material base and the ideological means of production, shaping dominant ideas.
在马克思看来，生产方式构成真实的基础，法律和政治的上层建筑由此耸立。统治阶级既控制物质基础，也控制意识形态的生产资料，塑造着主导思想。
Class struggle = Bourgeoisie vs Proletariat → Revolution
Contradictions between the owners of capital and the property-less workers intensify over time. When workers develop class consciousness (from a class ‘in itself’ to a class ‘for itself’), the result is revolutionary praxis.
资本所有者与一无所有的工人之间的矛盾会随着时间激化。当工人从“自在阶级”发展出“自为阶级”的阶级意识时，革命实践便随之而来。
Neo-Marxist revision: Relative autonomy of the state ⇌ Ideological apparatus
Althusser and Gramsci argued that the superstructure enjoys relative autonomy and that hegemony—consent engineered through civil society—is just as crucial as coercion.
阿尔都塞与葛兰西指出，上层建筑享有相对自主性，而霸权——通过公民社会制造的同意——与强制同样至关重要。
3. Interactionism: Meaning and the Social Self | 符号互动论：意义与社会自我
Interactionism turns attention to the micro-level, viewing social reality as constructed through everyday interactions and shared symbols. Its theorems stress interpretation, role-taking and the fluidity of meaning.
符号互动论将注意力转向微观层面，认为社会现实是通过日常互动和共享符号建构起来的。其“定理”强调诠释、角色扮演与意义的流动性。
Mead’s self = ‘I’ (subjective) + ‘Me’ (socialised self)
The self emerges from social experience: the ‘I’ acts, the ‘Me’ reflects society’s expectations. Through taking the role of the other, children internalise the ‘generalised other’.
自我产生于社会经验：‘I’是行动的主体，‘Me’则反映社会的期待。通过扮演他人角色，儿童内化了“概化他人”。
Goffman’s dramaturgy: Social interaction = Performance on a front stage + Backstage self
We manage impressions through sign vehicles, maintaining face and performing roles according to the audience. Stigmatised individuals engage in ‘passing’ or ‘covering’.
我们借助各种符号装备进行印象管理，根据观众来维护面子并扮演角色。蒙受污名的个体会采取“隐瞒”或“掩饰”策略。
Labelling theorem: Deviance = Behaviour × Societal reaction (Becker)
Deviance is not inherent in an act but created by the application of rules and labels. This can lead to a self-fulfilling prophecy and a deviant career.
越轨并非行为固有的属性，而是由规则与标签的应用创造出来的。这可能导致自证预言与越轨生涯。
4. Feminism: Patriarchy and Gender | 女权主义：父权制与性别
Feminist theory exposes the systematic inequality embedded in gender relations. Its central ‘axiom’ is that patriarchy operates across all institutions, from family to education and the state, and that gender is socially constructed.
女权主义理论揭露了嵌入性别关系中的系统性不平等。其核心“公理”是：父权制在所有制度中运作——从家庭到教育再到国家，且性别是一种社会建构。
Liberal feminism: Gender inequality = Sexist attitudes + Legal barriers
Campaigns for equal pay, education and reproductive rights gradually remove the obstacles to women’s achievement.
争取同工同酬、平等教育与生育权利的斗争能逐步消除女性成就的障碍。
Marxist feminism: Women’s oppression ∝ Capitalism × Unpaid domestic labour
Women’s domestic labour reproduces the workforce at no cost to capital, while their reserve army status keeps wages low.
女性的家务劳动无偿再生产了劳动力，而她们作为后备军的地位压低了整体工资。
Radical feminism: Patriarchy = Male power rooted in biology + violence
The patriarchal system is the primary oppression; liberation requires a fundamental restructuring of sexual and family relations.
父权制是首要的压迫体系；解放需要对性与家庭关系进行根本性重组。
5. Postmodernism: Fluidity and Fragmentation | 后现代主义：流动性与碎片化
Postmodernism rejects grand narratives and fixed identities, emphasising instead that social life is fragmented, fluid and saturated with media signs. Its theorems centre on choice, reflexivity and the death of meta-narratives.
后现代主义拒斥宏大叙事与固定身份，转而强调社会生活的破碎性、流动性与媒介符号的饱和。其“定理”围绕着选择、反思性与元叙事的死亡。
Baudrillard’s hyper-reality = Media images replace the real → Simulacra
In a media-saturated world, signs no longer refer to a deeper reality; people live in a world of simulations where the distinction between real and copy collapses.
在媒介饱和的世界中，符号不再指向深层现实；人们生活在仿真世界，真实与副本的界限已然崩塌。
Identity = Consumer choices × Lifestyle mix (Bauman)
Liquid modernity makes identity a lifelong, precarious project constructed through consumption. Individuals surf between temporary identities.
液态现代性使身份成为一个终身的、不稳固的建构过程，通过消费来完成。个体在不同临时身份之间游移。
Social change = De-traditionalisation + Risk (Beck/Giddens)
In a post-traditional society, people are forced to reflexively construct their own biographies, facing manufactured risks rather than fixed patterns.
在后传统社会，人们被迫反思性地建构自己的生命历程，面对的是人造风险而非固定模式。
6. Key Formulae for Family Sociology | 家庭社会学关键公式
The family, a core topic at AS level, can be understood through a set of theoretical propositions about its structure, functions and changing diversity.
家庭是 AS 阶段的核心主题，我们可以通过一组关于其结构、功能与多样性变迁的理论命题来理解它。
nctionalist nuclear family = Instrumental role (male) + Expressive role (female) (Parsons)
Parsons argued that the isolated nuclear family fits industrial society, with the husband performing the breadwinner role and the wife the nurturing role, benefiting all members.
帕森斯认为，孤立的核家庭契合工业社会，丈夫承担养家糊口的工具性角色，妻子担当情感抚慰的表达性角色，使所有成员受益。
Murdock’s four universal functions = Sexual + Reproductive + Economic + Educational
Every nuclear family fulfils these four essential functions; their breakdown would threaten the entire social order.
每个核家庭都履行这四项基本功能；如果这些功能受损，整个社会秩序将受到威胁。
Divorce rate ∝ Individualisation ↑ – Traditional norms ↓
Beck and Giddens link rising divorce to the pursuit of pure relationships and individual self-fulfilment, while feminists point to women’s growing economic independence.
贝克与吉登斯将离婚率上升与追求纯粹关系和个体自我实现相联系，而女权主义者则指向女性经济独立性的增强。
Family diversity = Cultural choice + Material constraint (Chester / Rapoports)
Five types of diversity—organisational, cultural, class, life-course and cohort—show that ‘the family’ is an ideological construct, not a fixed natural unit.
组织、文化、阶层、生命周期和同辈群体的五种多样性表明，“家庭”是一个意识形态建构，而非固定的自然单位。
7. Research Methods: Quantitative vs Qualitative | 研究方法：定量与定性
Sociological research rests on a spectrum between positivism and interpretivism. A handy ‘formula’ helps: the choice of method depends on the research question, theoretical stance and practical constraints.
社会学研究位于实证主义与解释主义的谱系之间。一个便捷“公式”有助于理解：方法的选择取决于研究问题、理论立场与实际限制。
Quantitative paradigm ∝ Measurable data × Statistical analysis → Generalisability
Surveys, structured interviews and official statistics yield numerical data that can identify patterns and test hypotheses about large populations.
问卷、结构式访谈与官方统计产生数字数据，能够识别模式并检验关于大总体的假设。
Qualitative paradigm ∝ Rich meaning × Context → Validity
Participant observation, unstructured interviews and documents uncover actors’ definitions and the processes behind social action, prioritising depth over breadth.
参与观察、非结构式访谈与文献揭示行动者的定义和社会行动背后的过程，优先考虑深度而非广度。
Triangulation = Method A + Method B → Cross-checking
Combining methods (e.g. survey + observation) compensates for the weaknesses of each and raises confidence in findings.
结合多种方法（例如问卷+观察）可以弥补各自的弱点，提高对研究发现的信心。
8. Validity, Reliability and Representativeness | 效度、信度与代表性
The quality of sociological data is judged by three central criteria. Their relationships can be expressed as a trade-off triangle.
社会学数据的质量由三个核心标准评判。它们的关系可以表示为一个权衡三角形。
Validity = Measuring what you intend to measure | 效度 = 测量到欲测之物
A valid study provides an accurate, authentic picture of social life, capturing actors’ real meanings rather than artificial responses.
一项有效的研究提供对社会生活的准确、真实的写照，捕捉行动者的真实意义而非人为应答。
Reliability = Consistency of results across time and researcher | 信度 = 结果在不同时间与研究者间的一致性
High reliability means the method can be replicated with the same outcomes, which typically requires standardised instruments.
高信度意味着方法可被复制并得出相同结果，这通常需要标准化工具。
Representativeness = Sample mirrors population | 代表性 = 样本反映总体
Generalisability depends on the extent to which the people studied are typical of the wider target group.
普遍性取决于被研究者能在多大程度上代表更广泛的目标群体。
Trade-off rule: Validity ↑ ↔ Reliability ↑ often inverse | 效度 ↑ ↔ 信度 ↑ 常常反向
In-depth qualitative methods often sacrifice reliability and representativeness for high validity, while quantitative surveys may do the opposite.
深度定性方法常为高效度而牺牲信度与代表性，定量调查则可能恰好相反。
9. Sampling: Types and Formulae | 抽样：类型与公式
Sampling is the process of selecting participants from a target population. Underlying each strategy is a simple ratio or logic.
抽样是从目标总体中选取参与者的过程。每种策略背后都蕴含一个简单的比率或逻辑。
Sampling fraction = n / N (n = sample size, N = population size)
A calculated fraction ensures that each member of the population has a known chance of selection in probability sampling.
在概率抽样中，计算出的抽样比确保总体每个成员都有已知的被选机会。
Simple random sample = List all → Random draw (unbiased but requires full sampling frame)
A random number generator selects individuals, giving equal chances, but the list may be incomplete.
随机数生成器选取个体，赋予均等机会，但名录可能不完整。
Stratified sampling = Divide population into strata → proportional random draw
This ensures key subgroups are represented, improving representativeness for diverse populations.
这使得关键子群体得到代表，提高了对异质性总体的代表性。
Non-probability shortcut: Snowballing → Contact → Referral → Chain
Used for hidden populations; starts with a small number of participants who recommend others, but it sacrifices representativeness.
用于隐藏群体；从少数参与者出发，由其推荐他人，但牺牲了代表性。
10. Ethical Principles: The Moral Calculus | 伦理原则：道德演算
Sociological research is governed by an ethical code designed to protect participants, researchers and the integrity of the discipline. Its maxims can be stated as a formula of permissible research.
社会学研究受到伦理规范的约束，旨在保护参与者、研究者与学科的诚信。其准则可以表述为一个容许研究的公式。
Ethical research = Informed consent × Confidentiality + No harm – Deception (unjustified)
Researchers must obtain voluntary, informed consent, guarantee anonymity, avoid physical and psychological harm, and minimise deception unless fully justified.
研究者必须获得自愿的知情同意，保证匿名性，避免身心伤害，并尽量减少欺骗，除非有充分理由。
Covert observation ⇌ Breach of consent vs Rarely necessary
Covert methods are ethically contentious because they deny the right to withdraw; they are permitted only when overt research would dangerously alter the subject.
隐蔽方法在伦理上有争议，因为它们剥夺了退出权；只有在公开研究会危险地改变研究对象时才被允许。
nerable groups → Extra protection (children, people with learning difficulties, prisoners)
Special safeguards are required, including gatekeeper consent and rigorously verified non-coercion.
需提供特殊的保障，包括守门人同意和严格核实非强制性。
11. Socialisation and Identity Formation | 社会化与身份形成
Socialisation is the lifelong process through which individuals internalise culture and develop a sense of self. The sociological ‘equation’ integrates nature, nurture and agency.
社会化是一个持续终身的进程，个体通过它内化文化并形成自我感。社会学“方程”整合了天性、教养与能动性。
Primary socialisation (family) → Basic norms, language, self-concept
Early interactions within the family ground the child in the norms and values of its culture, shaping core identity.
家庭中的早期互动使儿童扎根于其文化的规范与价值，塑造核心身份。
Secondary socialisation = School + Peer group + Media + Workplace
Later agencies transmit the universalistic standards of wider society, often reinforcing or challenging primary socialisation.
后续的施教者传递更广大社会的普遍性标准，常常强化或挑战初级社会化。
Identity = Social roles + Personal biography + Reflexivity (Giddens)
In late modernity, individuals must negotiate multiple, sometimes contradictory, identities, constantly writing their own narrative.
在晚期现代性中，个体必须协商多元的、有时相互矛盾的身份，不断书写自己的叙事。
12. Culture, Norms and Values | 文化、规范与价值观
Culture is the glue of social life. Sociologists treat norms and values as the invisible rules that govern behaviour, and their interplay forms a key theorem of social order.
文化是社会生活的粘合剂。社会学家将规范与价值观视为支配行为的无形规则，它们之间的相互作用构成了社会秩序的关键定理。
Culture = Material objects + Non-material symbols, beliefs, language
Culture provides a toolkit for solving daily problems; shared symbols enable communication and collective action.
文化为解决日常问题提供了工具包；共享的符号使得沟通与集体行动成为可能。
Social order = Norms (specific rules) + Values (general principles) + Sanctions
Deviance occurs when behaviour diverges from norms; sanctions—positive or negative—are applied to restore conformity.
当行为偏离规范时便出现越轨；正向或负向的制裁被用以恢复遵从。
