三、Bob 写了一篇文章介绍自然界中动植物对人类生活的贡献，他分享了这篇文章。阅读下面的短文，从短文后的 A～F 选项中，选出 5 个适当的选项补全短文。
Nature is full of wonderful plants and animals that are connected to our lives in many different ways. 1.
●Useful and Long-lasting Plants
Plants play an important role in our life. Redwood trees can grow to over 100 metres tall and weigh hundreds of tons. 2. Bamboo, which grows very quickly, can be used to make many things, such as furniture（家具）and musical instruments. In Asian countries, people often plant ginkgo trees（银杏树）because they can live for thousands of years, and their leaves are used in some medicines.
●Small Animals, Big Helpers
Small animals play a big role too. Butterflies with colourful wings help flowers by carrying pollen（花粉）from one to another. 3. Bees make honey in their honeycombs（蜂巢）. Frogs are helpful too because they eat insects that feed on crops. A frog can eat thousands of bad insects each year! 4.
●Small Wonders in Nature
When we go for a walk in nature, we might see mushrooms（蘑菇）under leaves or lotus flowers in the lakes. If we look closely enough, we might also find wild strawberries growing in the grass or pretty roses by the roadside.
All of these plants and animals are connected in the ecosystem（生态系统）. 5. This is why we must protect nature.
A. This process, known as pollination（授粉）, helps plants to produce seeds.
B. Let's explore some of these amazing connections!
C. This helps farmers grow healthy food for us all.
D. They help clean the air and are used to build houses.
E. However, not everyone understands their importance in the world.
F. Without them, our planet would lose its balance.

答案
1. B 2. D 3. A 4. C 5. F
解析
我们可以根据上下文逻辑逐一匹配选项：
1. 第一空前提到自然界的动植物以多种方式和人类生活息息相关，后文开始分板块介绍具体的关联内容，B选项“让我们来探索这些奇妙的联系吧！”可以完美承上启下，引出下文的介绍。
2. 第二空前提到红杉树可以长到100多米高、重达数百吨，D选项“它们可以净化空气，还能被用来建造房屋”中的They指代红杉树，承接前文介绍红杉的实际作用，逻辑通顺。
3. 第三空前提到彩色翅膀的蝴蝶通过把花粉从一朵花带到另一朵花来帮助花朵，A选项“这个被称为授粉的过程，能帮助植物结出种子”承接蝴蝶传粉的行为，解释该行为的意义，衔接自然。
4. 第四空前提到一只青蛙每年可以吃掉数千只害虫，C选项“这帮助农民为我们所有人种植出健康的食物”中的This指代青蛙吃害虫这件事，点明青蛙的作用给人类带来的好处，符合语境。
5. 第五空前提到所有这些动植物在生态系统中都是相互关联的，后文引出我们必须保护自然的结论，F选项“没有它们，我们的星球就会失去平衡”承接生态系统的关联性，点明动植物的重要性，顺理成章引出后文的保护自然的观点。
