Thanks, mdchachi. Is it that in your conversation you usually add the object noun after "study"? Do (a), (b), and (c) sound bookish?
Another native speaker says like this:
"My daughter is studying in Australia now" is correct, and it's natural and normal. And it's commonly said that way.
"My daughter studies in Australia now" is correct, but it doesn't sound natural.
What do you think?
How about these sentences without the object? Do they sound natural?
(f) Fred is studying to be a doctor.
(g) I'm studying under a well-known professor at London University.
(h) My son studies hard.
