How to remove rating page email and name fields

I am solved.

it should be discard the following code:

if ( get_option(‘require_name_email’) && !$user->exists() ) {
if ( 6 > strlen( $comment_author_email ) || ” == $comment_author ) {
wp_die( __( ‘ERROR: please fill the required fields (name, email).’ ), 200 );
} elseif ( ! is_email( $comment_author_email ) ) {
wp_die( __( ‘ERROR: please enter a valid email address.’ ), 200 );
}
}
