A big mistake in our online English classes. ‘All the time’ phrase should go at the end of a sentence, not after the verb or participle. So it is wrong to say ‘we have been all the time sleeping’ or ‘we are all the time watching TV’. We would need to say ‘we have been sleeping all the time’ or ‘we are watching TV all the time’. Remember: put ‘all the time’ at the end.
