答案

在第1、2、3、5题前面的括号内打“√”。

解析

【分析】
首先明确环保“3R”理念的核心是Reduce(减少资源消耗)、Reuse(重复使用物品)、Recycle(回收利用废弃物),解题时需逐一分析每个行为是否符合这三个原则,排除浪费资源的不符合项,确定符合要求的选项。
【解析】
先说明环保“3R”理念的三个内涵,再逐一分析各行为:
1. Bob双面使用纸张,减少了纸张浪费,符合Reduce原则,应打√;
2. Kate将旧玩具箱改作书箱,属于物品重复使用,符合Reuse原则,应打√;
3. Mike将废纸放入回收箱,属于废弃物回收利用,符合Recycle原则,应打√;
4. Linda出门不关电脑,浪费电能,不符合环保要求,不打√;
5. Jack骑车上学,减少化石能源消耗,符合Reduce原则,应打√;
6. Mary使用一次性纸杯,增加资源消耗和废弃物产生,不符合环保要求,不打√。因此符合要求的是第1、2、3、5题。
【答案】
在第1、2、3、5题前面的括号内打“√”。
【知识点】
环保3R原则,日常行为的环保判断
【点评】
本题结合日常行为考查对环保核心理念“3R”的理解,贴近生活实际,难度较低,需准确掌握3R含义并结合行为分析。

【解析】
任务一:1. 定位原文第一段“We have it on April 22nd.”,可知地球日在4月22日,对应选项B;2. 由原文“Litter makes Earth dirty. It pollutes our water and plants.”可知垃圾会使地球变脏,故pollute意为“使某物变脏”,选B;3. 原文第一段“We learn how to take care of our planet.”中take care of与look after同义,对应选项A。
