📚 Typical Example Questions Explained for IB & CIE Sciences | IB与CIE科学典型例题详解

Mastering science exams in IB and CIE curricula requires not only understanding core concepts but also practising typical questions that reveal the logic behind mark schemes. In this article, we explore representative problems from IB Physics, CIE Chemistry, IB Biology, and CIE IGCSE Physics. Each example is solved step-by-step, with bilingual commentary that highlights how to earn full marks.

掌握IB和CIE科学考试不仅需要理解核心概念，还需通过典型题目训练，理解评分逻辑。本文精选IB物理、CIE化学、IB生物和CIE IGCSE物理的代表性问题，逐步解析并配以中英评注，阐明满分策略。

1. Understanding the IB and CIE Science Syllabi | 理解IB与CIE科学教学大纲

IB Diploma Programme sciences (Biology, Chemistry, Physics) emphasize conceptual understanding, experimental skills, and data analysis. Questions often combine multiple topics and require extended written responses. CIE offers a range of science qualifications from IGCSE to A-Level; these exams are more modular, with structured questions testing specific learning outcomes. Knowing the syllabus structure is the first step to effective revision.

IB文凭科学课程（生物、化学、物理）注重概念理解、实验技能和数据分析，题目常融合多个主题，要求长篇书写回答。CIE则提供从IGCSE到A-Level的科学资格，考试更为模块化，结构性试题考查具体学习目标。了解教学大纲结构是高效复习的第一步。

2. Question Formats and Mark Schemes | 题型与评分方案

IB science papers include multiple-choice, data-based questions, and extended response (ER) questions that assess analysis and evaluation. Marks are awarded for correct answers, but also for showing working, using appropriate units, and clear logical steps. CIE structured questions often have part (a), (b), (c) guiding through calculations or explanations; marks are tightly linked to specific command words such as ‘calculate’, ‘explain’, or ‘suggest’.

IB科学试卷包含选择题、数据驱动题和评估分析与评价的论述题（ER）。得分点不仅在于正确答案，还在于展示步骤、使用正确单位和清晰的逻辑。CIE结构化试题常设有(a)(b)(c)小问引导学生计算或解释；评分严格对应指令词如“计算”“解释”或“建议”。

3. Example Question 1: IB Physics SL – Projectile Motion | 例题1：IB物理SL – 抛体运动

A football is kicked from the ground with an initial speed of 15 m s⁻¹ at an angle of 30° to the horizontal. Assume air resistance is negligible and g = 9.8 m s⁻². Calculate: (a) the time of flight; (b) the maximum height reached; (c) the horizontal range.
