循环中的变量

循环遍历一个结构体切片时，结构体的修改以及传递是怎样的？

package main
import "fmt"
type Person struct {
    Name string
}
func main() {
    persons := []Person{
        {Name: "John"},
        {Name: "Jane"},
        {Name: "Jack"},
    }
    var persons2 []Person
    for i, person := range persons {
        fmt.Printf("loop person addr: %p, name: %s\n", &person, person.Name)
        fmt.Printf("original person addr: %p, name: %s\n", &persons[i], persons[i].Name)
        persons2 = append(persons2, person)
    }
    for i := range persons2 {
        fmt.Printf("new person addr: %p, name: %s\n", &persons2[i], persons2[i].Name)
    }
}
