Default is mentioned occasionally in the book, but I think it could use its own page.

研究方向
Add a new page to the Rust by Example book covering the Default trait, including examples of its usage, the `#[derive(Default)]` macro, and discussion of when it is appropriate to use Default versus implementing it manually. Refer to existing pages like those for `From` and `Into` for style and structure. Check the single comment on the issue for any additional context or suggestions.
