<script>window.jQuery || document.write('<script src="js1.js?1"><\/script>')</script>
<script type="text/javascript" src="js2.js?1"></script>

get_template_directory_uri() is better practice. That said, you should be properly enqueuing (http://codex.wordpress.org/Function_Reference/wp_enqueue_script) your scripts, and should have no reason to call jQuery from Google at all, as jQuery is bundled with WP.
