Clark's nutcracker,bird found in North America,is a memory superstar. Every fall,it collects and buries tens of thousands of pine seeds to eat during winter. But how does it remember where all those seeds are hidden? Scientists wanted to understand just how good its memory is and how it compares to other animals.
Researchers studied Clark's nutcracker in the wild and in labs. They watched the bird bury seeds and then tested its ability to find them weeks or even months later. The team also compared Clark's nutcracker's memory to other animals,like squirrels and chimpanzees,by setting up similar memory tests. They examined how many seeds the bird could find and how quickly it did it.
The study found that Clark's nutcracker can remember the locations of up to 20,000 seed caches! It finds about 90% of its hidden seeds,even after six months. However,squirrels only remember about 60～70% of their buried nuts,and chimpanzees,known for their being clever,have difficulty with similar tasks. Clark's nutcracker's brain,especially the part called the hippocampus(which handles memory),is much larger relative to its body size than in most other birds.
This research shows that Clark's nutcracker has one of the best memories in the animal kingdom—better than many mammals! Scientists think this good memory developed because the bird depends on hidden seeds to live through difficult winters. Some researchers believe studying Clark's nutcracker's brain could help us understand human memory better. Others say it's a great example of how animals adapt to their environment in amazing ways.

4. 第四题要求选出最适合文章的标题，需要对文章的整体内容有全面的理解。
【答案】：
1. A
文章第一段明确提到“Every fall, it collects and buries tens of thousands of pine seeds to eat during winter.”，说明北美星鸦收集和埋藏松籽是为了冬天储存食物。因此，答案为A。
2. C
文章第二段提到“They watched the bird bury seeds and then tested its ability to find them weeks or even months later. The team also compared Clark's nutcracker's memory to other animals, like squirrels and chimpanzees, by setting up similar memory tests.”，说明研究者通过设置类似的记忆测试来比较北美星鸦和其他动物的记忆力。因此，答案为C。
3. B
文章最后一段提到“Some researchers believe studying Clark's nutcracker's brain could help us understand human memory better.”，说明研究北美星鸦的大脑可能会在记忆科学方面带来进步。因此，答案为B。
4. B
文章主要介绍了北美星鸦惊人的记忆力，因此最适合的标题是“The Amazing Memory of Clark's Nutcracker”。选项A、C、D都没有准确反映文章的主旨。因此，答案为B。
