Hello, <br/><br/>Could you please help me with the following question:<br/><br/>Is it possible to use the modal verb 'can' talking about possibility in the future? For example:<br/><br/>1. Chinese <b>can</b> become the most popular language in the world.<br/><br/>I think <u>may/might/could</u> are more popular in this case..Am I right? Is 'can' possible here, but maybe, less formal?<br/><br/>2. Chinese <b>may/might/could</b> become the most popular language in the world.<br/><br/>What about talking about possibility in the present? For instance:<br/><br/>3. She is not answering. She <b>can/may/might/could</b> be at work.<br/><br/>I think 'can' is ok, but less formal than 'may', 'might' and 'could'...<br/><br/>I would be grateful for your help,<br/><br/>Thank you in advance,<br/><br/>Coincidence
