The Greens were having a picnic. Empty bottles and plastic bags covered the grass. Suddenly, a spaceship appeared and an alien flew out.
“Hello! I'm Zaza from Planet Junk. My planet is like a huge dustbin, so I'm looking for a new home.” He looked around. “Someone told me Earth was beautiful, but this planet looks as dirty as mine!”
The Greens' faces turned red—they really shouldn't leave rubbish everywhere.
“Are those green things trees?” Zaza said excitedly, “On my planet, they were all cut down long ago, but you have so many. How lucky you are!”
At the same time, Mr Green noticed a newspaper with the title: More Rainforests Disappeared. His face burned. He quickly sat on it, trying to hide it.
Later, the Greens took Zaza to the beach. Mrs Green told him that people came here to play and relax, hoping to show Earth was still a nice place. But Zaza saw plastic bags, cans, newspapers and bottles everywhere. He even thought this was a “recycling centre”.
Then the Greens took Zaza to their home. As Mr Green opened the door, lights were on in every room, even though the family had been out all day.
Zaza said disappointedly, “I can't live on Earth. If you keep making so much rubbish and wasting so much energy, my planet's today will be yours tomorrow. Bye!”
As Zaza flew off, Mr Green stood still for a moment. “He's right. Let's clean up the rubbish and turn off the lights.”
High above, Zaza saw the green grass slowly becoming clean again. “Maybe there's hope,” he thought, and flew away.

【分析】
1. 第1题：先定位划线词“mine”所在句子，结合上下文，Zaza来自Planet Junk，他称地球和“我的（星球）”一样脏，由此判断mine指代他的星球。
2. 第2题：找格林先生藏报纸的原因，原文提到他“face burned（羞愧脸红）”，报纸标题是“More Rainforests Disappeared”，说明他因雨林消失的事实感到愧疚，所以藏报纸。
3. 第3题：直接在原文查找海滩上的物品，原文明确提到Zaza看到塑料袋、罐子、报纸，对应①②③。
4. 第4题：填空处需承接上下文，前文Zaza指出地球的问题，后文格林先生提出清理垃圾、关灯的行动，因此此处应表达“保护地球”的意思。
5. 第5题：主旨题需概括全文，文章通过外星人视角展现地球环境问题，目的是呼吁人们爱护地球。
【解析】
1. 细节理解题：根据第二段Zaza的话“I'm Zaza from Planet Junk... this planet looks as dirty as mine!”可知，mine指代Zaza的星球Planet Junk，故选C。
2. 推理判断题：根据第五段“His face burned. He quickly sat on it, trying to hide it.”，“face burned”体现格林先生的羞愧心理，报纸标题“More Rainforests Disappeared”让他因雨林消失的事实感到愧疚，故选B。
3. 细节理解题：根据第六段“But Zaza saw plastic bags, cans, newspapers and bottles everywhere.”，可知海滩上有塑料袋、罐子、报纸，对应①②③，故选A。
4. 推理判断题：前文Zaza指出地球的问题，后文格林先生提出“清理垃圾、关灯”的行动，因此填空处应表达“我们应该保护地球”，故选C。
5. 主旨大意题：全文通过外星人的经历揭示地球的环境问题，最终目的是呼吁人们关心、保护地球，故选D。
