1. Power, Authority and Legitimacy | 权力、权威与合法性
Power refers to the ability of an individual or group to influence or control the behaviour of others, even against their will. Authority, on the other hand, is power that is perceived as legitimate by those over whom it is exercised; it is based on consent rather than coercion. Legitimacy is the belief that a ruler, institution, or government has the right to rule, often derived from legal procedures, tradition, or popular support.
权力是指个人或群体影响或控制他人行为的能力，即使违背其意愿。而权威则是被行使对象认为是合法的权力；它基于同意而非强制。合法性是指人们相信统治者、机构或政府有统治的权利，通常源于法律程序、传统或民众支持。
According to Max Weber, authority can be classified into three ideal types: traditional authority (based on long-standing customs and inherited status, e.g., monarchs), charismatic authority (resting on the exceptional personal qualities of a leader, e.g., revolutionary figures), and legal-rational authority (derived from a system of established laws and procedures, e.g., elected officials in a democracy).
根据马克斯·韦伯的观点，权威可分为三种理想类型：传统权威（基于悠久习俗和世袭地位，如君主）、魅力权威（依赖于领袖非凡的个人品质，如革命人物）以及法理权威（源于既定的法律与程序体系，如民主国家的民选官员）。
Legitimacy can be maintained through democratic elections, effective governance, the rule of law, and ideological persuasion. When a government fails to meet public expectations or violates fundamental rights, a crisis of legitimacy may occur, leading to protests, rebellion, or regime change.
合法性可通过民主选举、有效治理、法治和意识形态说服来维持。当政府未能满足公众期望或侵犯基本权利时，便会出现合法性危机，引发抗议、叛乱或政权更迭。
2. Democracy and Authoritarianism | 民主与威权主义
Democracy is a system of government in which supreme power is vested in the people, exercised directly or through freely elected representatives. Key features include free and fair elections, protection of civil liberties, the rule of law, and political pluralism. Direct democracy involves citizens making decisions on policy themselves, while representative democracy elects officials to make decisions on their behalf. Liberal democracy further incorporates constitutional limits on government and the protection of individual rights.
民主是一种政府体系，最高权力属于人民，通过直接或自由选举的代表行使。关键特征包括自由公正的选举、公民自由的保护、法治和政治多元化。直接民主指公民自行就政策做出决策，而代议制民主则选举官员代表他们决策。自由民主政体还加入了宪法对政府的限制和个人权利的保护。
Authoritarianism is a political system characterised by concentrated power in a single leader or elite group, with limited political pluralism, weak rule of law, and restricted civil liberties. Citizens have little to no meaningful participation in decision-making. Forms include absolute monarchy, military dictatorship, and one-party states.
威权主义是一种政治制度，其特点是权力集中于单一领袖或精英集团手中，政治多元化有限，法治薄弱，公民自由受到限制。公民几乎没有或根本没有有意义的决策参与。形式包括绝对君主制、军事独裁和一党制国家。
Totalitarianism represents an extreme form of authoritarian rule in which the state seeks to control every aspect of public and private life, often through propaganda, state terror, and an official ideology. While all totalitarian systems are authoritarian, not all authoritarian regimes are totalitarian.
极权主义是威权统治的一种极端形式，国家试图通过宣传、国家恐怖和官方意识形态控制公共与私人生活的方方面面。尽管所有极权体制都是威权的，但并非所有威权政体都是极权主义的。
3. States, Government and Regimes | 国家、政府与政体
A state is a sovereign political entity defined by four key elements: a defined territory, a permanent population, a government, and the capacity to enter relations with other states (sovereignty). The government is the set of institutions through which public policy is made and enforced. A regime refers to the fundamental rules and norms that determine how power is exercised, often lasting beyond individual administrations.
国家是由四个关键要素界定的主权政治实体：明确的领土、常住人口、政府以及与其他国家交往的能力（主权）。政府是制定和执行公共政策的一整套机构。政体则指决定权力如何行使的基本规则和规范，通常比个别行政当局存续更久。
States can be organised in different ways. In a unitary system, sovereignty rests predominantly with the central government, and regional or local authorities derive their powers from the centre (e.g., France, Japan). A federal system divides sovereignty constitutionally between central and regional governments, each enjoying independent powers in certain areas (e.g., USA, India).
国家可以有不同的组织方式。在单一制下，主权主要归属于中央政府，地区或地方当局的权力由中央授予（如法国、日本）。联邦制则通过宪法在中央和地区政府之间划分主权，各自在特定领域享有独立权力（如美国、印度）。
Democratic governments further differ in the relationship between the executive and legislative branches. In a presidential system, the president is both head of state and head of government, elected separately from the legislature, and serves a fixed term (e.g., USA). In a parliamentary system, the executive (prime minister and cabinet) is drawn from the legislature and is accountable to it; the government can be removed by a vote of no confidence (e.g., UK).
民主政府在行政与立法部门的关系上也各有不同。总统制下，总统既是国家元首又是政府首脑，与立法机关分别选举产生，任期固定（如美国）。议会制下，行政机构（首相与内阁）出自立法机关并向其负责；政府可由不信任投票罢免（如英国）。
4. Constitutions and the Rule of Law | 宪法与法治
A constitution is a set of fundamental principles and rules that define the structure, powers, and limits of government, as well as the rights of citizens. It can be codified (a single written document, e.g., USA) or uncodified (found in statutes, conventions, and judicial decisions, e.g., UK). Constitutions may also be classified as rigid (requiring special procedures for amendment) or flexible (amendable like ordinary laws).
宪法是一整套基本原则和规则，界定了政府的结构、权力和限制以及公民的权利。它可以成文（单一书面文件，如美国）或不成文（存在于成文法、惯例和司法判例中，如英国）。宪法也可分为刚性（修改需要特殊程序）与柔性（可与普通法律一样修改）。
The rule of law is a foundational doctrine stating that no one is above the law, and that government power must be exercised within a legal framework. Key elements include equality before the law, legal certainty, access to justice, and an independent judiciary capable of reviewing executive and legislative actions.
法治是一项根本原则，它主张无人可以凌驾于法律之上，政府权力必须在法律框架内行使。其关键要素包括法律面前人人平等、法律的确定性、诉诸司法的渠道以及能够审査行政与立法行为的独立的司法机构。
Judicial independence ensures that judges can make decisions free from pressure by the other branches of government. In many democracies, the judiciary can declare laws unconstitutional through judicial review, thereby acting as a check on the legislature and executive.
司法独立确保法官能够不受其他国家权力分支的压力而做出裁决。在许多民主国家，司法机关可以通过司法审查宣布法律违宪，从而成为对立法与行政的制衡手段。
5. Elections and Voting Systems | 选举与投票制度
Elections serve multiple functions: they legitimise government, enable peaceful transfer of power, hold representatives accountable, and provide citizens with a means of political participation. The choice of voting system significantly shapes party competition and representation.
选举具有多重功能：使政府合法化、实现权力和平转移、让代表承担责任，并给予公民政治参与的途径。投票制度的选择极大地影响着政党竞争和代表性。
The first-past-the-post (FPTP) system awards a seat to the candidate with the most votes in each constituency, even if that is not an absolute majority. It tends to produce single-party majority governments and a clear link between constituents and their MP, but can under-represent smaller parties and create many 'wasted' votes.
简单多数制（FPTP）将席位授予各选区得票最多的候选人，即使未达到绝对多数。它倾向于产生单一政党多数政府，并在选民与议员之间建立明确联系，但可能使小党代表性不足并产生大量“浪费”的选票。
Proportional representation (PR) systems allocate seats in proportion to the share of votes each party receives. This results in more accurate representation of voter preferences and often leads to coalition governments. Variants include the party list system and the single transferable vote (STV), where voters rank candidates in order of preference.
比例代表制（PR）按照各政党得票比例分配席位。这使得选民偏好能得到更准确反映，往往导致联合政府。变体包括政党名单制和可转移单票制（STV），后者中选民按偏好顺序排列候选人。
Mixed-member proportional (MMP) systems combine elements of FPTP and PR. Voters typically cast two votes: one for a constituency candidate and one for a party list. This aims to balance local representation with overall proportionality, as seen in Germany.
混合成员比例制（MMP）结合了简单多数制和比例代表制的要素。选民通常投两票：一票给选区候选人，一票给政党名单。这旨在平衡地方代表性与整体比例性，如德国所采用的模式。
6. Political Parties and Party Systems | 政党与政党制度
Political parties are organised groups that seek to win government power, usually by contesting elections. Their functions include representing societal interests, aggregating and articulating demands, recruiting and training political leaders, formulating policy programmes, and providing a basis for stable government and opposition.
政党是为了赢得政府权力而参与选举的有组织团体。其功能包括代表社会利益、汇集和表达诉求、招募和培训政治领袖、制定政策纲领以及为稳定的政府与反对派提供基础。
Party systems describe the number of parties that have a realistic chance of participating in government and the patterns of party competition. A one-party system allows only one legal party (e.g., China under CPC leadership). A two-party system is dominated by two major parties alternating in power (e.g., historically the USA). A multiparty system features several parties competing, often resulting in coalition governments (e.g., Netherlands). A dominant-party system exists when one party consistently wins elections despite the presence of other parties (e.g., South Africa under the ANC).
政党制度描述有实际机会参与政府的政党数量及政党竞争模式。一党制只允许一个合法政党（如中国在共产党领导下的体制）。两党制由两大政党轮流执政（如历史上的美国）。多党制有多个政党竞争，经常导致联合政府（如荷兰）。主导党制指尽管存在其他政党，但一党始终赢得选举（如南非非国大执政时期）。
Parties are often located along a left-right ideological spectrum. Left-wing parties typically support social equality, welfare, and state intervention in the economy, while right-wing parties emphasise individual freedom, free markets, and traditional values. The centre ground contains parties advocating moderate policies combining elements of both left and right.
政党常被置于左右意识形态光谱上。左翼政党通常支持社会平等、福利和国家干预经济，而右翼政党强调个人自由、自由市场与传统价值观。中间地带则是主张融合左右翼元素的温和政策政党。
7. Pressure Groups and Social Movements | 压力集团与社会运动
A pressure group (or interest group) is an organised body that seeks to influence government policy or public opinion without seeking to win political office itself. They differ from political parties in that their primary goal is to advance a specific cause or the interests of a particular section of society rather than to govern.
压力集团（或称利益集团）是一种有组织的团体，旨在影响政府政策或公众舆论，而不寻求获得政治官职。它们与政党的不同之处在于，其主要目标是推动特定事业或社会某一部分的利益，而非执政。
Pressure groups can be classified as sectional (protective) groups, which represent a defined section of society, such as trade unions or professional associations, and promotional (cause) groups, which advocate for a particular cause or value, like environmental protection or human rights. Insider groups enjoy regular access to policymakers, while outsider groups rely on public campaigning and indirect influence.
压力集团可分为代表社会明确群体的部门（保护性）集团，如工会或专业协会，以及倡导特定事业或价值的促进（事业）集团，如环保或人权组织。内部人集团可定期接触决策者，而外部人集团则依赖公众运动和间接影响。
Methods used by pressure groups include lobbying, litigation, public demonstrations, media campaigns, and civil disobedience. Social movements are broader, more informal networks of individuals and groups pursuing large-scale social or political change, such as the civil rights movement or the anti-globalisation movement.
压力集团使用的方法包括游说、诉讼、公众示威、媒体宣传和公民不服从。社会运动是更广泛、更非正式的个人与团体网络，追求大规模社会或政治变革，如民权运动或反全球化运动。
8. The Executive, Legislature and Judiciary | 行政、立法与司法
The three branches of government each perform distinct functions. The executive (e.g., president or prime minister and cabinet) is responsible for implementing laws and directing the day-to-day administration of the state. It sets policy agendas, conducts foreign relations, and commands the armed forces.
政府的三个分支各自履行不同职能。行政机关（如总统或首相与内阁）负责执行法律，指导国家的日常行政管理。它制定政策议程、开展对外关系并统帅武装力量。
The legislature (parliament or congress) performs law-making, representation, oversight, and deliberation. It passes legislation, approves budgets, and holds the executive to account through questions, debates, and committees. In parliamentary systems, the executive is drawn from and accountable to the legislature, whereas in presidential systems, the two branches are more distinct and operate with separate mandates.
立法机关（议会或国会）履行立法、代表、监督和审议职能。它通过法案、批准预算，并通过质询、辩论和委员会监督行政。在议会制中，行政出自立法机关并向其负责；而在总统制中，两个分支更为独立，以分立的授权运作。
The judiciary interprets and applies the law, settles disputes, and protects individual rights. An independent judiciary is a cornerstone of the rule of law. In many states, courts possess the power of judicial review, enabling them to invalidate laws or executive actions that conflict with the constitution. The separation of powers, where no single branch controls all government functions, serves as a safeguard against tyranny.
司法机关解释和适用法律，解决争端并保护个人权利。独立的司法是法治的基石。在许多国家，法院拥有司法审查权，能够废止与宪法冲突的法律或行政行为。权力分立，即任何单一分支不得控制政府全部职能，是防范暴政的保障。
9. Political Ideologies | 政治意识形态
An ideology is a coherent set of ideas that provides a vision of society, a critique of the existing order, and a programme for political action. The major ideologies studied in IGCSE Politics include liberalism, conservatism, socialism, nationalism, and feminism.
意识形态是一套连贯的观念体系，它提供社会愿景、对现存秩序的批评以及政治行动纲领。IGCSE政治课程学习的主要意识形态包括自由主义、保守主义、社会主义、民族主义与女权主义。
Liberalism emphasises individual freedom, equality before the law, limited government, and a market economy. Classical liberals advocate minimal state intervention, while modern liberals accept a role for the state in ensuring welfare and equal opportunities.
自由主义强调个人自由、法律面前人人平等、有限政府和市场经济。古典自由主义者主张国家最低限度干预，而现代自由主义者接受国家在保障福利和机会平等方面的作用。
Conservatism values tradition, order, and authority, believing that institutions that have stood the test of time embody accumulated wisdom. Conservatives are cautious of radical change and emphasise the importance of social stability, often supporting a mixed economy and strong national identity.
保守主义重视传统、秩序和权威，认为经受时间考验的制度体现了累积的智慧。保守主义警惕激进变革，强调社会稳定的重要性，通常支持混合经济和强大的民族认同。
Socialism advocates social ownership or regulation of the means of production, seeking to reduce inequality and promote collective welfare. Democratic socialism works within the electoral system to achieve gradual reform, whereas revolutionary socialism calls for the overthrow of the capitalist state.
社会主义主张生产资料的社会所有或调控，以减少不平等并增进集体福利。民主社会主义在选举体制内争取渐进改革，而革命社会主义则号召推翻资本主义国家。
Nationalism holds that the nation should be the fundamental unit of political organisation and that national interests should be placed above others. Civic nationalism is based on shared political values and citizenship, while ethnic nationalism is rooted in common language, culture, or descent. Feminism contends that society is characterised by gender inequality and seeks to dismantle patriarchal structures across all spheres of life.
民族主义认为民族应是政治组织的基本单位，民族利益应高于其他。公民民族主义基于共享的政治价值观和公民身份，而族裔民族主义根植于共同语言、文化或血统。女权主义主张社会以性别不平等为特征，并力求在生活各领域消除父权结构。
10. International Politics and Global Governance | 国际政治与全球治理
The international system is defined by sovereign states interacting in an environment that lacks a central global authority (anarchy). Key concepts include national sovereignty, the balance of power, and international cooperation. International organisations play a crucial role in facilitating cooperation and managing conflict.
国际体系由各主权国家在缺乏中央全球权威（无政府状态）的环境下互动构成。关键概念包括国家主权、权力平衡与国际合作。国际组织在促进合作、管理冲突方面发挥关键作用。
The United Nations (UN) is the most prominent global organisation, comprising 193 member states. Its principal organs include the General Assembly (deliberative, all members), the Security Council (responsible for maintaining peace, with five permanent veto-wielding members), and the International Court of Justice. The UN also runs specialised agencies such as the WHO and UNICEF.
联合国（UN）是最重要的全球性组织，由193个成员国组成。其主要机构包括大会（审议机构，全体成员）、安全理事会（负责维护和平，五个常任理事国拥有否决权）和国际法院。联合国还下设有专门机构，如世卫组织和儿童基金会。
Regional organisations, like the European Union (EU), go beyond simple cooperation to involve economic and political integration. The EU has its own legal order and supranational institutions, with members pooling sovereignty in certain areas. Other regional blocs include the African Union (AU) and ASEAN.
区域组织，如欧洲联盟（EU），超越了简单合作，涉及经济与政治一体化。欧盟拥有自身的法律体系和超国家机构，成员国在某些领域集中主权。其他区域集团包括非洲联盟（AU）和东盟。
Globalisation refers to the increasing interconnectedness of the world in terms of trade, communication, culture, and politics. It has created opportunities for growth and collaboration but also challenges such as economic interdependence, cultural homogenisation, and transnational problems like climate change and terrorism. Global governance attempts to address these issues through a combination of formal institutions, regimes, and norms.
全球化是指世界在贸易、通信、文化、政治方面日益紧密的联系。它为增长与合作创造了机遇，也带来了经济相互依赖、文化同质化以及气候变化和恐怖主义等跨国问题的挑战。全球治理试图通过正式机构、体制和规范的结合来应对这些问题。
