【分析】
本题为英语选词填空题型,解题思路如下:1. 先通读每个句子,理解句意,明确空缺处所需的词性(如名词、形容词等);2. 结合给定单词(dirty、use、top、side、less、more),根据语法规则(如名词变复数、形容词变形等)和句意,对单词进行适当形式调整;3. 逐一匹配句子,确保语义通顺、语法正确。
【解析】
1. 句意为“我们应该用纸的两面来节约资源”,both后接可数名词复数,side的复数形式为sides,故填sides;
2. 句意为“我们老师分享了一些关于遵循‘3R’规则的有用想法”,此处需形容词修饰名词ideas,use的形容词形式为useful,故填useful;
3. 句意为“这些好建议能帮我们节约更多水”,结合语境,此处需表示“更多”的词修饰不可数名词water,more符合,故填more;
4. 句意为“不要一次洗你的脏衣服”,此处需形容词修饰名词clothes,dirty为形容词,符合句意,故填dirty;
5. 句意为“LED灯用更少的电,所以用它能节能”,此处需修饰不可数名词electricity的比较级,less符合,故填less;
6. 句意为“迈克分享了他的三个顶尖减少能源浪费的想法”,top作形容词表示“顶尖的”,top three为固定搭配,故填top。

1. sides 2. useful 3. more 4. dirty 5. less 6. top

Ⅲ. Read and finish the tasks.(阅读短文,完成下列任务。)
Hello, my name is Leo. I'm a Grade Six student. Now, “low-carbon life”(低碳生活)is popular around us. It means saving energy and saving our Earth. My family and I try to live a low-carbon life every day.
I usually go to school by bus. When it rains, my dad drives me, but we always carpool with my classmate Tom. At home, we never leave the lights on when we go out. My mum uses the same cloth bags for shopping every time instead of plastic bags. We also collect(收集) waste paper and bottles to recycle them. At the weekend, we sometimes plant trees in the community with our neighbours.
Low-carbon life is easy and important. It helps make our Earth greener and more beautiful.
任务一:根据短文内容,选择正确答案。

)1. What does the word “carpool” mean?
A. 拼车 B. 搭顺风车 C. 打车

)2. Which is the best title for the passage?

任务三: Because it helps make our Earth greener and more beautiful.
解析:
【分析】本题为英语阅读理解题,包含三个任务:任务一需结合上下文猜测词义、把握文章主旨选标题;任务二需区分“3R”原则(Reduce减少、Reuse重复使用、Recycle回收)并匹配文中行为;任务三需从原文定位低碳生活重要的原因,解题时需仔细阅读短文,提取关键信息作答。
【解析】任务一:1. 根据短文第二段“when it rains, my dad drives me, but we always carpool with my classmate Tom”,可知下雨时爸爸开车带Leo,和同学Tom一起,carpool意为“拼车”,故选A;2. 全文围绕Leo一家的低碳生活展开,A选项“家庭成员”、B选项“上学方式”均片面,C选项“我家的低碳生活”符合主旨,故选C。任务二:Reduce(减少)对应减少能源消耗的行为,即①坐公交上学、③出门关灯、⑤和Tom拼车;Reuse(重复使用)对应重复利用物品,即②每次用同一个布袋购物;Recycle(回收)对应回收可利用物品,即④收集废纸和瓶子。任务三:从短文最后一段最后一句“It helps make our Earth greener and more beautiful”可知,Leo认为低碳生活重要的原因是它有助于让地球更绿更美丽。
【答案】任务一:1. A 2. C;任务二:Reduce—①③⑤;Reuse—②;Recycle—④;任务三:Because it helps make our Earth greener and more beautiful.
