class List_PendingVerify extends Rs_List {
    public function __construct($id) {
        $this->id = $id;
    }

    protected function loadData() {
        echo $this->id;
    }
}

I recommend reading the Classes and Objects documentation. (In particular, the Properties section is relevant here.)
