如何将Go接口扩展到另一个接口？

I have a Go interface:

type People interface {
    GetName() string
    GetAge() string
}

Now I want another interface Student:

1.

type Student interface {
    GetName() string
    GetAge() string
    GetScore() int
    GetSchoolName() string
}

But I don't want to write the duplicate function GetName and GetAge.

Is there a way to avoid write GetName and GetAge in Student interface ? like:

2.

type Student interface {
    People interface
    GetScore() int
    GetSchoolName() string
}

You can embed interface types. See the Interface type specification

type Student interface {
    People
    GetScore() int
    GetSchoolName() string
}

This is a full example about interface extend:

package main

import (
    "fmt"
)

type People interface {
    GetName() string
    GetAge() int
}

type Student interface {
    People
    GetScore() int
    GetSchool() string
}

type StudentImpl struct {
    name string
    age int
    score int
    school string
}

func NewStudent() Student {
    var s = new(StudentImpl)
    s.name = "Jack"
    s.age = 18
    s.score = 100
    s.school = "HighSchool"
    return s
}

func (a *StudentImpl) GetName() string {
    return a.name
}

func (a *StudentImpl) GetAge() int {
    return a.age
}

func (a *StudentImpl) GetScore() int {
    return a.score
}

func (a *StudentImpl) GetSchool() string {
    return a.school
}


func main() {
    var a = NewStudent()
    fmt.Println(a.GetName())
    fmt.Println(a.GetAge())
    fmt.Println(a.GetScore())
    fmt.Println(a.GetSchool())
}
