You could add this after the_content() or the_excerpt() inside the loop in your template:
<?php if( is_syndicated() ) { ?>
Read the <a href="<?php the_syndication_permalink(); ?>" target="_blank">Full Article</a> at <a href="<?php the_syndication_source_link(); ?>" target="_blank"><?php the_syndication_source(); ?></a>
<?php } ?>
