阅读短文，掌握其大意，然后从 A、B、C、D 中选出可以填入空白处的最佳选项。
Memory research may seem to relate only to the brain, but it can actually have a big influence on the ecological (生态的) environment.
Scientists have been studying the memory of animals. They found that many animals ¹. a good memory to survive in the wild. For example, some birds can remember the ². of thousands of nuts they have hidden for the winter. If we understand how these animals' memories work, we can better ³. their habitats (栖息地).
In one study, researchers focused on bees. Bees have an amazing memory for ⁴. They can remember the location of flowers and the best routes to get to them. However, due to the ⁵. of pesticides (农药) and the loss of natural habitats, bees are facing great challenges. By studying the memory of bees, scientists hope to find ways to ⁶. them. They know that if bees can't find enough food because of environmental changes, it will ⁷. not only the bees but also the whole ecosystem (生态系统)
Another area of research is about how human memory can help protect environment. When people have a ⁸. memory of the beautiful natural view they have seen, they are more likely to take action to protect it. For example, if someone remembers the clear rivers and lush forests from their childhood, they will be ⁹. to see these places destroyed. So, education can play a role in improving people's memory of the environment. By teaching children about the importance of nature and showing them the beauty of the natural world, we can raise the awareness of environmental protection in their hearts.
In conclusion, memory research is not just a study. It helps us understand and ¹⁰. the ecological environment. By protecting and developing the memory-related abilities of both animals and humans, we can work towards a more sustainable (可持续的) future.
