Translate the button “More News” at news theme Focus?

Translation

How do I translate the button “More News” in functions.php?

?>
<a class=”dropdown-toggle” data-toggle=”dropdown” href=”#”>
<span class=”number”> <? php echo $ r-> post_count;?> </ span>
<span> <? php echo $ display_type == ‘today’ && $ is_news_today? __ (‘Tonight’, ‘dw_focus’): __ (‘More News’, ‘dw_focus’);?> <i Class=”icon-caret-down”> </ i> </ span>
</ a>
<? php

More News was translated, but could not find the place that can translate the word “NO MORE NEWS”, where I can find? I would translate this word. It’s good if your news theme have more translate version.

Thanks,
