Describe the following photographs.
There is just one spelling mistake.
There really isn't anything that needs correcting. If I was being picky I'd change it to this:
"Her boyfriend is tall. This Th at elephant is huge. These Those children are small."
Generally in English speech, the word 'this/these' would sometimes imply that the speaker has that object with them. "Look at these shoes" you'd most probably say if you were picking the shoes up or stood next to them. Or, "Have you seen this photograph?" you'd most probably say if you had the photograph with you.
You'd instead say "Look at those shoes" is you were pointing them out from a distance or "have you seen that photograph?" if you were pointing it out on a wall.
Thanks, Luke! Your comments always are precise and in the right place.
You're very welcome :)
