Hello, writeacher and other helpers.
Good to see you again. I'd like to use the questions and answers for the asking and answering activity with people. Would you take a look at the questions and answers? If there are expressions which are not appropriate, let me know them. I'd like to use correct expressions.

All look really good except for some minor corrections in 6 and 7.

5. Do they have a dog? Yes, they do.
6. What is it? It's a dog. Coming right after #5, in which you've already said they have a dog, it'd probably be better to say what kind of dog it is. "It's a Shih-tzu" or "It's a Collie" or something like that.
7. What's the dog's name? It's June. / He name is June. / Its name is June. I would have the answer to this question be "Her name is June."

Nice work.

=)
