Hi,<br/><br/>How can I use the word 'half' and 'outside' correctly? Do you have some tips?<br/><br/>1. Half the class is fully involved in the activity.<br/><br/>Why not?<br/><br/>Half of the class is fully involved in the activity.<br/><br/>2. John is standing outside the school.<br/><br/>I think you can't say:<br/><br/>John is standing outside of the school. Why not?<br/><br/>How about this? Is this correct?<br/><br/>Outside of the school lies an electrical pole.
