问题因为页面一进来 就是讲义页面，所有我要让讲义 默认选中正常点击切换的时候，正常没有问题，当前选中为红色，其它变为灰色路由代码

Answer 1

那你进来就要让页面调到讲义页面啊.
vue-router提供了redirect属性

Answer 2

{

    path: '/teachingResearch/lecture',

    component: TeachingResearch,

    children: [

        {

            path: '/teachingResearch/lecture',

            component: Lecture

        },

        {

            path: '/teachingResearch/paper',

            component: Paper

        },

        {

            path: '/teachingResearch/question',

            component: Question

        }

    ]

}

这应该是可行的。

修改答案，补充。

{

    path: '/teachingResearch',

    redirect: '/teachingResearch/lecture'

},

{

    path: '/teachingResearch/lecture',

    component: TeachingResearch,

    children: [

        {

            path: '/teachingResearch/lecture',

            component: Lecture

        },

        {

            path: '/teachingResearch/paper',

            component: Paper

        },

        {

            path: '/teachingResearch/question',

            component: Question

        }

    ]

}
