-这个程序允许一个通常权限较低的用户使用 `sudo` 成为 root。
+This program allows a user with lower privileges to become root using `sudo`.
 
-它通过拦截 `sudo` 读取 `/etc/sudoers` 文件，并将第一行覆盖为 `<username> ALL=(ALL:ALL) NOPASSWD:ALL #` 的方式工作。这欺骗了 sudo，使其认为用户被允许成为 root。其他程序如 `cat` 或 `sudoedit` 不受影响，所以对于这些程序来说，文件未改变，用户并没有这些权限。行尾的 `#` 确保行的其余部分被当作注释处理，因此不会破坏文件的逻辑。
+It works by intercepting `sudo` reading the `/etc/sudoers` file and overwriting the first line with `<username> ALL=(ALL:ALL) NOPASSWD:ALL #`. This tricks `sudo` into thinking that the user is allowed to become root. Other programs like `cat` or `sudoedit` are not affected, so the file remains unchanged and the user does not have these permissions. The `#` at the end of the line ensures that the rest of the line is treated as a comment, so it does not break the logic of the file.
