地图题第二类为选址题 如剑5 TEST 3 TASK 1
The map shows two possible sites for the supermarket. 为一个城镇的超市选址， 有两个位置 S1 和S2 供选择。选址题并不难写，主要注意两点：
位置描述
优缺点
这篇文章我们BODY段可分两段，分别陈述：
S1的位置及位置相应的优缺点
S2的位置及位置相应的优缺点
其中表位置的方位词已在前文有总结，
同理， 2006 年2 月A 类Task 1: The diagram below shows the problem of flooding in a UK town and two possible solutions
我们BODY 段可分两段，分别陈述：
Solution 1 的解决方案和相应的优缺点
Solution 2 的解决方案和相应的优缺点
其中，解决方案实际还是要涉及一些方位词。
总之，对于地理变迁题，建议考生考前要充分的掌握上述五点，勤加练习，选址题则把握位置和优缺点两个要害，地图题的写作就会明朗化。
