剑桥 IGCSE 国际数学（0607）大纲旨在通过广泛的数学技能挑战学生，从基础的数值运算到高级问题解决。与标准 IGCSE 数学（0580）不同，0607 试卷包含更多的探究性任务，更强调图形计算器的使用，并注重在真实情境中应用数学。了解试卷 1 至 4 的结构和常见题型，对于有重点地复习和自信应对考试至关重要。
1. Exam Structure and Format | 试卷结构与格式
The 0607 assessment consists of four compulsory written papers taken in a single examination series. Candidates follow either the Core curriculum (Papers 1 & 2, grades C–G available) or the Extended curriculum (Papers 3 & 4, grades A*–E available). Papers 1 and 3 are non-calculator papers lasting 45 minutes and 1 hour 45 minutes respectively, while Papers 2 and 4 permit the use of a graphics calculator and last 1 hour 15 minutes and 1 hour 45 minutes. All papers consist entirely of structured, multi-part questions; there are no multiple-choice sections.
0607 考试由同一考季的四份必考笔试卷组成。考生选择 Core 级别（试卷 1 和 2，可获得 C–G 等级）或 Extended 级别（试卷 3 和 4，可获得 A*–E 等级）。试卷 1 和 3 为不允许使用计算器的试卷，时长分别为 45 分钟和 1 小时 45 分钟；试卷 2 和 4 允许使用图形计算器，时长分别为 1 小时 15 分钟和 1 小时 45 分钟。所有试卷全部由结构化的多步骤问题组成，没有选择题。
Each paper tests the same topic areas — number, algebra, functions, geometry, mensuration, trigonometry, vectors, transformations, statistics, and probability — but with increasing depth and complexity. Extended papers introduce topics such as logarithmic and exponential functions, trigonometric identities, and calculus, which are not covered in the Core syllabus. Marks range from short answer calculations to extended reasoning and proof.
每份试卷都测试相同的知识领域——数、代数、函数、几何、测量、三角学、向量、变换、统计和概率——但深度和复杂度逐步增加。Extended 试卷引入了 Core 大纲不包含的对数与指数函数、三角恒等式以及微积分等主题。题目分值涵盖从简短的计算到扩展推理和证明。
2. Number and Set Language Questions | 数与集合语言题型
These questions appear early in every paper and assess understanding of integers, fractions, decimals, percentages, ratio, and standard form. A typical Core question might ask: ‘Express 0.000305 in standard form’ or ‘Calculate the percentage increase when a salary rises from $2400 to $2880.’ Extended students must also handle recurring decimals, upper and lower bounds, and fractional indices.
这类题目出现在每份试卷的前面，考查整数、分数、小数、百分数、比和标准形式的掌握。典型的 Core 题目可能是：“将 0.000305 表示为标准形式”或“计算工资从 2400 美元涨到 2880 美元的百分比增长”。Extended 学生还需处理循环小数、上下界和分数指数。
Set language is unique to the 0607 syllabus. Questions involve interpreting Venn diagrams, listing elements of sets, and describing shaded regions using ∪, ∩, and complement notation. For instance, ‘Shade the region (A ∩ B) ∪ C’ in a given Venn diagram’ or ‘Given ε = {1,2,3,…,10}, A = {factors of 12}, B = {even numbers}, list A ∩ B.’
集合语言是 0607 大纲的独特内容。题目要求解释韦恩图、列出集合元素，并使用 ∪、∩ 和补集符号描述阴影区域。例如，在给定的韦恩图中“标出 (A ∩ B) ∪ C 的区域”或“已知全集 ε = {1,2,3,…,10}, A = {12 的因数}, B = {偶数}，列出 A ∩ B”。
3. Algebra and Sequences | 代数与数列题型
Algebraic manipulation forms the backbone of the exam. Candidates simplify expressions, expand brackets, factorise quadratics, and change the subject of complex formulae. A Core paper might require factorising x² − 9y², while an Extended paper could ask students to solve x² − 5x + 3 = 0 by completing the square and express the answer in surd form: x = (5 ± √13) / 2.
代数运算是考试的基础。考生需要化简表达式、展开括号、分解二次三项式，并变换复杂公式的主项。Core 试卷可能要求分解 x² − 9y²，而 Extended 试卷可能要求学生通过配方法解 x² − 5x + 3 = 0，并用根式表达答案：x = (5 ± √13) / 2。
Sequences include linear, quadratic, and, at Extended level, exponential patterns. Common question formats are: ‘Find the nth term of the sequence 3, 7, 11, 15, …’ or ‘The nth term of a sequence is n² + 2n. Determine the 10th term.’ Extended students are also tested on finding limits of sequences and using sequence notation to model growth and decay.
数列包括线性、二次，以及在 Extended 级别出现的指数模式。常见题型有：“找出数列 3, 7, 11, 15, … 的第 n 项”或“某数列的第 n 项为 n² + 2n，求第 10 项。”Extended 学生还要测试求数列极限以及用数列符号对增长和衰减建模。
4. Functions and Graph Questions | 函数与图像题型
Functions are a major focus in 0607. Students must understand function notation, find inverses, and compose functions. A typical Extended question: ‘f(x) = 2x + 3 and g(x) = x² − 1. Find fg(x) and f⁻¹(x).’ Many problems also require sketching and interpreting graphs — including linear, quadratic, cubic, reciprocal, exponential, and trigonometric graphs up to 360°.
函数是 0607 的重点。学生必须理解函数符号、求反函数和复合函数。典型的 Extended 题：“f(x) = 2x + 3, g(x) = x² − 1，求 fg(x) 和 f⁻¹(x)。”许多问题还要求绘制和解读图像——包括线性、二次、三次、倒数、指数以及 360° 以内的三角函数图像。
Non-calculator papers often have questions asking to plot graphs on provided grids and solve equations graphically. Calculator papers introduce regression, curve fitting, and modelling using the graphics calculator to find best-fit lines or curves for given data sets. Understanding asymptotes, intercepts, and turning points is essential for higher marks.
非计算器试卷常有要求在所提供的方格纸上绘制图像并通过图像解方程的题目。计算器试卷则引入回归、曲线拟合和建模，使用图形计算器为给定数据集找到最佳拟合直线或曲线。理解渐近线、截距和驻点对于获得高分至关重要。
5. Equations, Inequalities, and Simultaneous Equations | 方程、不等式和联立方程题型
Linear and quadratic equations appear in every exam series. Core students solve simple linear equations and inequalities such as 2x + 5 < 17, while Extended candidates tackle quadratic inequalities like x² − 6x + 8 ≤ 0 and must present the solution on a number line. Fractional equations requiring clearing denominators are also common.
线性方程和二次方程出现在每次考试中。Core 学生解简单的线性方程和不等式，如 2x + 5 < 17，而 Extended 考生需解决二次不等式，例如 x² − 6x + 8 ≤ 0，并要在数轴上表示解集。需要去分母的分式方程也很常见。
Simultaneous equations may involve two linear equations, or one linear and one quadratic. The calculator paper might use a graphics calculator to find intersection points, while the non-calculator version requires algebraic methods such as substitution or elimination. A classic question: ‘Solve the simultaneous equations: y = x² + 2x − 1 and y = 5x − 3.’
联立方程可能涉及两个线性方程，或一个线性一个二次方程。计算器试卷可能使用图形计算器求交点，而非计算器版本要求代数方法，如代入法或消元法。经典题目：“解联立方程：y = x² + 2x − 1 和 y = 5x − 3。”
6. Geometry and Mensuration | 几何与求积题型
These questions cover properties of angles, triangles, circles, polygons, and 3D shapes. Candidates apply angle facts on parallel lines, circle theorems, and the Pythagorean theorem. Mensuration problems require calculating lengths, areas, surface areas, and volumes; formulas for prisms, pyramids, cones, and spheres are given in the formula sheet, but students must select and apply them correctly.
这类题目涵盖角度性质、三角形、圆、多边形和三维图形。考生需应用平行线角度关系、圆定理和勾股定理。求积问题要求计算长度、面积、表面积和体积；棱柱、棱锥、圆锥和球体的公式均提供在公式表中，但学生必须正确选择并应用。
Extended questions often combine geometry with algebra, for instance using similarity to set up equations, or finding the volume of a frustum by subtracting two similar cones. Bearings and scale drawings are tested, and a question might read: ‘A ship sails 45 km on a bearing of 130°, then 28 km on a bearing of 220°. Calculate its distance from its starting point.’
Extended 题目常将几何与代数结合，例如利用相似列出方程，或通过相减两个相似圆锥求截头体的体积。方位角和比例绘图也被考查，题目可能为：“一艘船以方位角 130° 航行 45 公里，再以方位角 220° 航行 28 公里，求船与起点的距离。”
7. Trigonometry | 三角学题型
Trigonometry appears across both Core and Extended papers. Core syllabi include right-angled triangle trigonometry (sin, cos, tan), the sine rule, and the cosine rule for non–right triangles. Extended syllabi extend to the ambiguous case of the sine rule, exact values of sin, cos, tan for 30°, 45°, 60°, and solving trigonometric equations such as sin 2θ = 0.5 for 0° ≤ θ ≤ 360°.
三角学在 Core 和 Extended 试卷中均有出现。Core 大纲包括直角三角形三角学（正弦、余弦、正切），以及非直角三角形的正弦定理和余弦定理。Extended 大纲扩展到了正弦定理的歧义情形，30°、45°、60° 的精确三角函数值，以及解三角方程，如 sin 2θ = 0.5，0° ≤ θ ≤ 360°。
Graph sketching of y = sin x, y = cos x, and y = tan x is frequently examined, as are transformations of these graphs. Calculator papers allow graphic exploration of periodic functions, while non-calculator papers expect analytical solutions using identities such as tan θ = sin θ / cos θ and sin²θ + cos²θ = 1.
y = sin x、y = cos x 和 y = tan x 的图像绘制经常被考到，这些图像的变换也是考点。计算器试卷允许对周期函数进行图形探索，而非计算器试卷则期望使用恒等式，如 tan θ = sin θ / cos θ 和 sin²θ + cos²θ = 1 进行分析解答。
8. Vectors and Transformation Geometry | 向量与变换几何题型
Vector questions include addition, subtraction, multiplication by a scalar, finding position vectors, and proving collinearity or parallelism. In the Extended paper, students must also determine the magnitude of a vector using |v| = √(x² + y²). Typical phrasing: ‘Given a = 3i + 4j, find |a| and the unit vector in the direction of a.’
向量题包括向量的加法、减法、数乘，求位置向量，以及证明共线或平行。在 Extended 试卷中，学生还必须使用 |v| = √(x² + y²) 确定向量的模。典型表述：“已知 a = 3i + 4j，求 |a| 以及 a 方向的单位向量。”
Transformation geometry covers reflections, rotations, translations, and enlargements, including negative and fractional scale factors. Students must describe transformations fully and use matrix representation for transformations in the Extended course. For instance, ‘Describe fully the single transformation represented by the matrix (0 1; -1 0).’ Combined transformations and invariant points are high-mark challenges.
变换几何涵盖反射、旋转、平移和放大，包括负的和分数的比例因子。学生必须完整描述变换，并在 Extended 课程中使用矩阵表示变换。例如：“完整描述由矩阵 (0 1; -1 0) 表示的单一变换。”组合变换和不变点是高分挑战。
9. Statistics and Probability | 统计与概率题型
Statistical questions demand interpreting and constructing bar charts, pie charts, histograms, cumulative frequency curves, box-and-whisker plots, and scatter diagrams. Median, quartiles, interquartile range, and standard deviation are tested. In calculator papers, students input data lists and use statistical functions; non-calculator papers may provide grouped frequency tables for estimating the mean.
统计题要求解读并绘制条形图、饼图、直方图、累积频率曲线、箱线图和散点图。中位数、四分位数、四分位距和标准差是考查内容。在计算器试卷中，学生输入数据列表并使用统计功能；非计算器试卷可能提供分组频率表以估算平均数。
Probability ranges from simple events to tree diagrams with conditional probability. Common questions: ‘A bag contains 5 red, 3 blue, and 2 green marbles. Two are drawn without replacement. Find the probability both are blue.’ Extended candidates handle combined events, Venn diagrams with probability notation, and expected frequency problems.
概率题从简单事件到含条件概率的树状图。常见问题：“袋中有 5 个红球、3 个蓝球和 2 个绿球。不放回地抽取两个。求两个都是蓝球的概率。”Extended 考生处理组合事件、带概率符号的韦恩图以及期望频数问题。
10. Problem Solving and Investigative Tasks | 问题解决与探究性任务题型
The 0607 syllabus places significant weight on applying mathematics to unfamiliar, multi-step problems. These tasks often appear at the end of each paper and require combining techniques from different topics — for instance using algebra to solve a geometry problem, or interpreting a real-life scenario involving compound interest and graph modelling. Students must read carefully, extract relevant data, and plan a logical solution pathway.
0607 大纲非常重视将数学应用于不熟悉的多步骤问题。这类任务常出现在每份试卷末尾，需要结合不同主题的技术——例如用代数解决几何问题，或解读涉及复利和图像建模的现实情境。学生必须仔细阅读，提取相关数据，并规划合乎逻辑的解题路径。
Common pitfalls include misinterpreting the demand, rounding errors, and failing to show structured working. Examiners award marks for method even if the final answer is wrong, so step-by-step reasoning is crucial. Practising past papers under timed conditions, reviewing marking schemes, and mastering the graphics calculator’s functions give candidates a strong advantage.
常见陷阱包括误解题目要求、舍入误差以及不展示结构化解题过程。即使最终答案错误，考官也会对正确的方法给分，因此逐步推理至关重要。在限时条件下练习历年真题、研读评分方案并掌握图形计算器的功能，能给予考生巨大的优势。
11. Use of Graphics Calculator | 图形计算器的使用题型
A unique feature of the 0607 exam is the graphics calculator requirement for Papers 2 and 4. Questions are designed to test the ability to store functions, find roots, calculate numerical derivatives, and perform statistical regressions. For example, you might be asked to ‘Use your GDC to solve the equation eˣ = 5 − x², giving the coordinates of the points of intersection to three significant figures.’
0607 考试的独特之处在于试卷 2 和 4 要求使用图形计算器。题目旨在测试存储函数、求根、计算数值导数以及执行统计回归的能力。例如，可能会要求“使用你的图形计算器解方程 eˣ = 5 − x²，给出交点坐标，保留三位有效数字”。
Non-calculator papers indirectly prepare for calculator use, but success in the calculator paper demands fluency with the device’s menus, such as setting up tables, adjusting window settings, and tracing graphs. Candidates who rely on the calculator as a black box often make data-entry mistakes, so examiners recommend verifying results through algebraic understanding whenever possible.
非计算器试卷间接为计算器的使用做准备，但在计算器试卷中取得成功需要熟练操作设备菜单，例如设置数表、调整窗口设置和追踪图像。那些将计算器当作黑箱使用的考生常常犯数据输入错误，因此考官建议尽可能通过代数理解来验证结果。
12. Final Tips and Common Pitfalls | 最终建议与常见陷阱
Success in 0607 is not just about knowing content — it is about applying it efficiently and accurately under time pressure. Allocate revision time across all topics, prioritize weaker areas, and focus on the command words used in questions: ‘show that’, ‘hence’, ‘find the exact value’, and ‘explain why’ each require a slightly different approach. For non-calculator papers, mental arithmetic and estimation skills are particularly valuable for checking answers.
在 0607 中取得成功不仅在于掌握知识内容——更在于在时间压力下高效准确地应用知识。在复习中分配时间到所有主题，优先强化薄弱领域，并关注题目中使用的指令词：“证明”、“由此”、“求精确值”和“解释为什么”分别需要稍有不同的解题策略。对于非计算器试卷，心算和估算能力对检查答案尤其宝贵。
Above all, every mark counts, so never leave a question unanswered — attempt all parts, even if only to write down relevant formulas or first steps. With systematic preparation, a clear understanding of the paper structures, and plenty of timed practice, the 0607 International Mathematics examination becomes a manageable and rewarding challenge.
最重要的是，每一分都算数，决不要留空白——尝试作答所有部分，哪怕只是写下相关的公式或第一步。通过系统准备、清晰理解试卷结构以及大量的限时练习，0607 国际数学考试将成为一项可控且回报丰厚的挑战。
