type Base struct {
    Name string
}

func (base * Base) Foo() {
    fmt.Println("Base Foo : ", base.Name)
}

func (base * Base) Bar() {
    fmt.Println("Base Bar : ", base.Name)
}

type Foo struct {
    Base
    a int 
}

func (foo * Foo) Bar() {
    foo.Base.Bar()
    fmt.Println("\tFoo Bar : ", foo.Name)
}

func main() {
    var str string = "hello world"

    base := &Base{str}
    base.Foo()

    str = "Ni hao"
    foo := &Foo{Base{str}, 0}
    foo.Bar()
    foo.Foo()
}

2、运行

$ go run combination.go 
Base Foo :  hello world
Base Bar :  Ni hao
    Foo Bar :  Ni hao
Base Foo :  Ni hao
