Could a native help me with these few sentences?<br/><br/><b>Is big hurry correct? Should it be great hurry or a different adverb?</b><br/><br/>1 If they were late they would have been in a big hurry.<br/><br/><b>I heard this said, could you tell me if there are any grammatical problems please?</b><br/><br/>2 I'd be inclined to think more so that he did do it rather than he didn't do it.<br/><br/><b>Is there anything missing in this sentence? I seems the schhol is too poor to be flaunting a phone?</b><br/><br/>3 Your school is way too poor to be flaunting such a mobile phone around at your age.<br/><br/><b>This is incorrect, whats correct please?</b><br/><br/>4 I'm not so lazy to not do that for you. I would do it if you asked me.<br/><br/>Thank you very much
