go to THE place

[Nanatuha]

Dear teachers.
I realized there are two pattern about "go to THE place" as I was reading a text book.
One pattern have the definite article THE and other pattern haven't it.

There is:
She wanted to go to the school.
We go to the school together with you.

There isn't:
You don't have to go to school today.
She goes to school.

What difference is there between them? Does the former describe a certain "school" and latter describe "school" as one kind? (not hospitals, not shops, they are schools)

Thanks for your help.

Does the former describe a certain "school" and latter describe "school" as one kind? (not hospitals, not shops, they are schools)

"the" is specific. Use it to narrow the noun's semantic scope:

Let's go to the school. (Q: Go to what school? A: The school I attend.)
Let's go to the school around the corner.
Let's go to school. (school in general)

Thanks a lot. I got it clearly.
