B
Imogen Napper has been asking questions since she was a little girl. Why? was her favorite. When she found beaches near her hometown, which she remembered as clean, covered by a thick blanket of plastics, she wondered why it happened and decided to be part of the solution.
She looks for ways plastic gets into the environment through pathways we wouldn't often consider. In her earliest research on face washes, around 100,000 microplastic beads(微塑料球) were found to be used per wash. This meant a huge amount of microplastics were traveling down household sinks and into water systems each time people washed their faces. Napper's findings influenced buyers, and consequently, the law, which banned the use of microbeads in products worldwide. “That lit the fire for my determination to find other ways to protect the planet,” she says of her career(职业) path.
Now she is called a plastics detective(侦探), which hits the nail on the head. Napper has spent years sweeping the world for traces of plastic where it doesn't belong. She investigated how much we were polluting the ocean from washing our clothes, finding around 700,000 microfibers could float into the environment in a typical clothes wash. She even found the presence of microplastics near the peak of Mount Everest. Her work “keeps getting higher and higher”, as she puts it. For her latest study, she sets her sights on the final frontier, working to protect space before litter becomes a threat there.
With plastic making its way to the edges of the earth, Napper remains hopeful that small changes, like choosing products with less plastic and extending the lifespan of our clothing, are doable and will have a positive impact. “By using the plastic-free bottle, you are preventing millions of microplastic beads from entering the ocean.” Her tip is simple, “Fixing plastic pollution is like a huge jigsaw puzzle. Each one of us is a puzzle piece and we just need to put them all together!”

【语篇解读】本文是一篇记叙文。文章主要讲述了主人公Imogen Napper在保护环境方面做出的贡献。
4. B 解析:推理判断题。根据第一段的内容“Imogen Napper从小就一直在问问题。‘为什么？’是她的最爱。当她在家乡附近发现她记得很干净的海滩被厚厚的塑料覆盖着时，她想知道为什么会发生这种情况，并决定成为解决方案的一部分”可推知，从第一段我们可以了解Napper的好奇心很强。故选B。
5. A 解析:推理判断题。根据第二段中“In her earliest research... she says of her career path.(在她对洗面奶的早期研究中，她发现每次洗面奶使用约10万个微塑料珠。这意味着每次人们洗脸时，大量的微塑料会顺着家庭水槽进入供水系统。Napper的发现影响了买家，并因此影响了法律，该法律禁止在世界各地的产品中使用微塑料珠。她谈到自己的职业道路时说：‘这件事点燃了我寻找其他方式保护地球的决心’。”可推知，Napper先前研究的成功让她选择了这个职业。故选A。
6. D 解析:词句猜测题。根据第二段中“She looks for ways plastic gets into the environment through pathways we wouldn't often consider.(她寻找塑料通过我们不常考虑的途径进入环境的方式)”以及画线词所在句“Now she is called a plastics detective... (现在她被称为‘塑料侦探’……)”可知，此处为“现在她被称为‘塑料侦探’，这真是说到点子上”。故可猜测画线短语hits the nail on the head为“一针见血，说到点子上”，和D选项Gives a suitable description“给出合适的描述”意思相近。故选D。
7. C 解析:推理判断题。根据最后一段的内容“随着塑料走向地球的边缘，Napper仍然希望小的改变，比如选择含有更少塑料的产品和延长我们衣服的寿命，都是可行的，并且会产生积极的影响。‘通过使用无塑料瓶，你可以防止数百万微塑料珠进入海洋。’她的建议很简单，‘解决塑料污染就像一个巨大的拼图游戏。我们每个人都是一块拼图，我们只需要把它们拼在一起！’”可推知，我们能从最后一段Napper的话中学到“每个行动都会产生影响”这个道理。故选C。
