I take the liberty to make some comments on your composition: I don't think a good composition can be just a collection of many simple sentences. When describing a thing, sentences should be fluent and coherent. It is best to avoid using the same words or sentences to express the same thing. Your composition, if translated into Chinese, will probably look like this:

This is our school. Welcome to visit. Gymnasium [I guess you mean the gymnasium,

Gymnasium),

Not gum.

(Gummy candy, or rubber)]

Behind the garden, the garden is next to the library, the library is in front of the teaching building, the dining room is next to the teaching building, and the playground is between the school gate and the bathroom. The school is beautiful.

Is it a bit like "just putting the single sentence together"?

Let me try to rewrite the article as follows to see if you will feel better:
