These days, I'm always feeling strange about one sentence frequently used. It is:<br/><br/><b><u>There are many things need to be done.</u></b><br/><br/>I know this sentence could be devided into 2 separate parts:<br/><br/><i>1) There are many things.</i> <i>2) The things need to be done</i><br/><br/>But, I guess there's one word 'that' is omitted in this sentence. The full sentence should be:<br/><br/>There are many things that need to be done.<br/><br/>I'm not quite sure whether there's any grammar error with this sentence. Your help will be appreciated.
