欢迎来到 WJEC 七年级物理历年真题深度解析。通过分析真实的考试题型，我们可以总结出常考主题、核心指令词以及拿到满分所需的具体步骤。无论是计算速度、描述能量转移还是预测电路行为，这份指南都会磨练你的考试技巧并增强你的自信心。

1. Speed, Distance and Time Calculations | 速度、距离与时间计算

One of the most frequently tested skills in Year 7 is using the formula speed = distance ÷ time. You must be able to rearrange it to find any unknown and always include the correct unit, typically metres per second (m/s).

七年级最常考查的技能之一是使用公式 速度 = 距离 ÷ 时间。你必须能够变形公式求出未知量，并且始终写上正确的单位，通常是米每秒 (m/s)。

Sample Past Paper Question: A student walks 240 metres to school in 120 seconds. Calculate her average speed. (2 marks)

真题示例： 一名学生步行 240 米去上学，耗时 120 秒。计算她的平均速度。(2 分)

Step 1 – Write down what you know: distance = 240 m, time = 120 s.

步骤 1 – 写下已知量： 距离 = 240 米，时间 = 120 秒。

Step 2 – State the formula and substitute: speed = distance ÷ time = 240 ÷ 120.

步骤 2 – 写出公式并代入： 速度 = 距离 ÷ 时间 = 240 ÷ 120。

Step 3 – Calculate and give the
