Google Translate Script on Each New Post

Folks, kindly suggest, how and what to modify to have this script inserted automatically on a top of each new post and page?

Reference: https://translate.google.com/manager/website

Script:

<div id="google_translate_element"></div><script type="text/javascript">
function googleTranslateElementInit() {
  new google.translate.TranslateElement({pageLanguage: 'ru', layout: google.translate.TranslateElement.InlineLayout.HORIZONTAL}, 'google_translate_element');
}
</script><script type="text/javascript" src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>

Please note, I am NOT asking for any “plugins”, but for WP script modification.

Thank you.

( Love WP! )
