四、Sam 给学校英语杂志社的编辑写了一封邮件，分享了自己关于环保的一些想法。请阅读这封邮件，判断下列句子的正误，正确的写“T”，错误的写“F”。
Dear Editor,
I'm Sam from Green School. Our Mother Earth is running out of resources. But it's not too late. We can do something to change this. Here are my ideas.
To save energy, I use a solar-powered light in my garden. It gets energy from the sun, so it can save electricity. I also draw the curtains(拉窗帘) on hot days. It keeps my room cool, so I can use the air conditioner less. To reduce waste, I don't buy drinks in plastic bottles. I make my own juice at home. I also bring my own bags to shops and markets. To reuse things, I turn old glass jars into little gardens. I grow small plants in them. I also turn old T-shirts into shopping bags.
My parents also do these things every day. We think every little thing helps!
Sincerely,
Sam

【分析】
做此类判断正误题，需先提取每个小题的核心信息，再回到原文中定位对应语句，将题目表述与原文细节逐一比对，信息完全一致则判断为“T”，不一致则为“F”。
【解析】
1. 原文第二段明确表述“To save energy, I use a solar-powered light in my garden.”，与题目“Sam uses a solar-powered light in his garden.”完全一致，故判断为T；
2. 原文第二段提到“I also draw the curtains on hot days. It keeps my room cool, so I can use the air conditioner less.”，说明Sam在热天拉窗帘的目的是保持房间凉爽，与题目表述一致，故判断为T；
3. 原文第二段指出“To reduce waste, I don't buy drinks in plastic bottles.”，即Sam不买塑料瓶装饮料，题目中“Sam often buys drinks in plastic bottles.”与之矛盾，故判断为F；
4. 原文第二段提到“I turn old glass jars into little gardens. I grow small plants in them.”，“them”指代前文的旧玻璃罐，与题目“Sam grows small plants in old glass jars.”一致，故判断为T；
5. 原文第二段说明“I also bring my own bags to shops and markets.”，即Sam购物用自己的袋子而非塑料袋，题目“Sam uses plastic bags for shopping.”与之矛盾，故判断为F；

五、提升题▶请阅读下面故事的开头,发挥你的想象力,把Leo运用“3R”原则帮助地球的故事补充完整。至少出现2种节能做法,不少于50词。
One Saturday morning, Leo went to the park with his mum. He saw a lot of plastic bottles on the grass. “Mum, look at all these bottles!” Leo said. “What can we do?”

Leo looked at the bottles and got an idea. "Mum, we can collect and reuse them," he said. Then he picked up the bottles and put them into a bag. At home, Leo cleaned the bottles. He used one as a pencil holder and gave another to his mum to grow flowers in. "Now the park is clean, and we have new useful things!" Leo said happily.

【分析】
首先明确题目要求：需结合故事开头，运用“3R”原则（减量化、再利用、再循环）补充Leo帮助地球的故事，至少包含2种节能/环保做法，字数不少于50词。解题思路为：承接上文Leo和妈妈看到塑料瓶的场景，联想3R中的“再利用”（Reuse）原则，设计具体的环保做法，最后点明环保意义，满足题目要求。
【解析】
1. 承接开头：Leo看到塑料瓶后想到“再利用”的环保做法；
2. 具体做法：收集塑料瓶，清洗后改造成笔筒、花盆，这两种均为符合3R原则的节能/环保行为；
3. 收尾：点明此举既清洁了公园，又减少了浪费，呼应帮助地球的主题，符合字数要求。
【答案】
Leo looked at the bottles and got an idea. "Mum, we can collect and reuse them," he said. Then he picked up the bottles and put them into a bag. At home, Leo cleaned the bottles. He used one as a pencil holder and gave another to his mum to grow flowers in. "Now the park is clean, and we have new useful things!" Leo said happily.
