答案：任务一：1. B 2. A 3. C
任务二：1. B 2. B
任务二：1. B 2. B
解析：
任务一：首先明确三个环保R原则的含义：Reduce指减少不必要的消耗和浪费，Reuse指不随意丢弃旧物、重复使用现有物品，Recycle指回收废弃物重新加工制作新物品。1空属于Reduce板块，B选项“少用塑料吸管，改用金属吸管”是减少一次性塑料浪费的行为，符合Reduce的要求；2空属于Reuse板块，后文提到用物品种植小花，A选项“不要扔掉旧花盆”符合重复利用旧花盆种花的语境，属于Reuse行为；3空属于Recycle板块，C选项“我们回收旧书来制造新纸”属于回收再加工的行为，符合Recycle的要求。
任务二：1. 原文里“把旧衣服做成袋子”的内容归类在Reuse板块，属于重复利用物品的行为，因此选B；2. 原文Recycle板块明确说明要把可回收物品放进蓝色垃圾桶，因此选B。
任务二：1. 原文里“把旧衣服做成袋子”的内容归类在Reuse板块，属于重复利用物品的行为，因此选B；2. 原文Recycle板块明确说明要把可回收物品放进蓝色垃圾桶，因此选B。
