public function demo5(){
        //使用hasWhere根据article的条件查询(注:comment与article有关联),同时使用with把article查询出来:
        $list = Comment::hasWhere('article',[["title","like","%美国%"]])->with("article")->select()->toArray();
             //或者,效果一样
        $list = Comment::with(['article'=>function($query){
            $query->where("title","like","%量子%");
