欢迎来到 SQA 七年级地理单元测试模拟卷解析。这份练习卷旨在帮助你复习关键的地理技能和知识，包括地图阅读、自然地理、人地互动和可持续发展实践。每个部分呈现一道测试题、正确答案和详细解析，以加深你的理解。
1. Map Scale Calculation | 地图比例尺计算
Question 1: A map has a scale of 1:25,000. You measure a straight-line distance of 8 cm between two points. What is the actual ground distance in kilometres?
题目 1：一张地图的比例尺为 1:25 000。你测得两点间的直线距离为 8 厘米。实际地面距离是多少公里？
Answer: 2 km.
答案：2 公里。
viding by 100 (200,000 ÷ 100 = 2,000 m), then to kilometres by dividing by 1,000 (2,000 ÷ 1,000 = 2 km). Always remember to check the units: many students forget to convert cm to km and mistakenly write 200,000 km.
解析：计算实际距离时，将图上距离乘以比例尺分母。8 厘米 × 25 000 = 200 000 厘米。把厘米转换为米除以 100（200 000 ÷ 100 = 2 000 米），再转换为公里除以 1 000（2 000 ÷ 1 000 = 2 公里）。务必检查单位：许多学生忘记将厘米转换为公里，错误地写成 200 000 公里。
2. Compass Directions | 罗盘方向
Question 2: You stand at point A. You walk 300 metres due north, then 400 metres due east. What is the general direction of your finishing point (point B) from point A?
题目 2：你站在 A 点。向正北走 300 米，然后向正东走 400 米。从 A 点看，终点 B 大致在什么方向？
Answer: Northeast.
答案：东北方向。
Explanation: Moving north and then east places you diagonally between north and east. The exact direction is northeast. A compass rose shows eight cardinal and intercardinal directions; northeast is exactly halfway between north and east. If you imagine a right-angled triangle, the journey forms the two shorter sides, so the straight-line direction from A to B is northeast. Using a compass, it would be at an azimuth of 45° from north.
解析：先向北再向东走，你的位置就在北和东的对角线上。确切的方向是东北。罗盘花显示八个基本和象限方向；东北恰好是北和东的中间。如果你想象一个直角三角形，这两段路程构成两条短边，因此从 A 到 B 的直线方向就是东北。用罗盘测量，它与正北的方位角为 45°。
3. Six-Figure Grid References | 六位数字网参考
Question 3: On an Ordnance Survey map, a landmark is recorded with the six-figure grid reference 453217. What do the first three digits (453) tell you?
题目 3：在 Ordnance Survey 地图上，一个地标的六位数字网参考是 453217。前三位数字（453）告诉你什么？
Answer: The eastings – how far east to travel across the map.
答案：东距——在地图上向东移动的距离。
Explanation: In a six-figure grid reference, the first three digits refer to the eastings (moving east along the bottom of the map), and the second three digits (217) refer to the northings (moving north up the side). The number 453 means you locate the grid line 45, then estimate three tenths further east. This system gives a much more precise location than a four-figure reference. Practise reading the numbers: 'along the corridor and up the stairs' – eastings before northings.
解析：在六位数字网参考中，前三位数字代表东距（沿地图底部向东移动），后三位数字（217）代表北距（向上沿边线向北移动）。数字 453 表示你先找到东距格线 45，再向东估计十分之三。这个系统比四位数字参考更精确。记住口诀：“先走走廊再上楼梯”——先读东距，再读北距。
4. Contour Lines and Slope Steepness | 等高线与坡度
Question 4: A contour map shows lines at 10-metre vertical intervals. In area X, the contour lines are spaced very close together. What does this indicate about the slope in area X? Explain briefly.
题目 4：一张等高线图的等高距为 10 米。在 X 区域，等高线非常密集。这说明 X 区域的坡度有什么特点？请简要解释。
Answer: The slope is steep. Closely spaced contours mean that the height changes rapidly over a short horizontal distance.
答案：坡度很陡。密集的等高线意味着在很短的平距内高度变化很大。
Explanation: Contour lines join points of equal elevation. When they are close together, the ground rises or falls sharply, like a cliff
