Hi Jordana, 1) "AT&T does mobile, TV and internet." - while I have no grammatical reasons for saying so, as a native speaker I would use "provides" or something similar, rather than "does". We would be a little more precise. ;) I would, however, say "CNN doesn't do a hard-hitting reporting", but the "a" needs to be taken out for it to make sense: "CNN doesn't do hard-hitting reporting". 2)"Do you say ceramic tile floor, ceramic tile, or ceramic flooring or ceramic floor?" I would say "ceramic tile flooring", since "flooring" is the general term used when talking about floor materials. ;) "We are getting a new ceramic tile floor/ceramic floor" or "We are getting a new ceramic tile floor/ceramic floor laid"? Both would work, you'd just need the correct term - "We are getting new ceramic tile flooring" or "We are getting new ceramic tile flooring laid". 3) In this case, I would say that "drawing a red line in the sand" means that he states the limits of what he will accept, and if the limits are crossed, it will happen again. What they wrote doesn't quite make sense, I think that both of your suggestions are correct. I hope this helps, all my grammar knowledge comes from German so I have just considered what I myself would say!
