主题：Tusk of Narwhal

1. First, the narwhal dwells and hunts within the Arctic Circle, where the sea is often covered with thick pack ice. Like other whales, the narwhal needs air to breathe and cannot stay underwater indefinitely. Eyewitnesses have reported seeing narwhals use their tusks to pierce through the ice sheet from below. The ability to break the ice in this way would give a narwhal access to air whenever it needed to take a breath. That would make it possible for narwhals to freely hunt in waters that are covered with ice.

1. First, if you apply pressure to a normal tusk. It will actually bend about thirty centimeters in any direction. This flexibility means that it cannot really be used for breaking through an ice sheet that is more than a few cent meters thick. The reason narwhals are able to spend long periods of time in the sea that's covered with ice is that the ice sheets typically break up by themselves in certain places. Supposed observations of narwhal ‘s piercing through an ice sheet, they have simply been narwhals seen sticking their heads out of the water in places where the ice sheet had already begun to break up.

2. Second, the tusk could serve as a weapon for fighting with other male narwhals as they compete for territory. Just as rams and male deer charge at one another with their horns or antlers, male narwhals, it seems, may charge or joust with one another. Some observers have claimed to have seen aggressive clashing of tusks between male narwhals.

2. What the second theory in the reading passage probably refers to is a behavior observed in male narwhals called tusking. The reason that some observers may have mistaken tusking for an aggressive behavior is that they observed it from a distance. People who have observed the narwhals husking up close give very different accounts. Instead of ?, tusking generally seem to gently rob their tusks. That's more consistent with some sort of communication role, rather than defending territory.

3. Third, the surface of the tusk contains many millions of microscopic holes connected to nerves. This configuration suggests that the tusk serves as a sensor that allows the narwhal to detect ocean properties, for example water pressure, temperature, salinity of the water, and even barometric pressure above the water's surface. The ability to sense such properties would be an important adaptation aiding in the narwhal's survival.

3. Third, as to the usefulness of the tusk for detecting properties of the ocean important for survival. Well, consider this. Almost all male narwhal have tusks, but very few female narwhal have the structure. Furthermore. Female narwhals live longer than male narwhals. If the function of the tusk was to give the animal information needed for survival, why wouldn't females have tusks as well? And since they don't. How do we explain their greater longevity?

　　Technology has undoubtedly revolutionized the way children learn and interact with the world around them. With the vast array of digital tools and resources available at their fingertips, children today have more opportunities to express their creativity and imagination than ever before. With programs like Adobe Photoshop and Procreate, children can now create intricate digital artwork with just a few clicks of a mouse or taps on a screen. This allows them to experiment with different techniques and styles, pushing the boundaries of their creativity. Furthermore, technology has also opened up new avenues for children to collaborate and share their creative work with others. Platforms like YouTube and TikTok allow children to showcase their talents to a global audience, receiving feedback and inspiration from peers around the world. This not only encourages children to think outside the box but also fosters a sense of community and support for their creative endeavors. In conclusion, technology has undoubtedly made children more creative than before by providing them with new tools, platforms, and opportunities to express themselves. By embracing the benefits of technology while also encouraging a diverse range of creative experiences, children can continue to push the boundaries of their imagination and innovation in the digital age.
