Grammer. The definite article "the"

I got feedbacks about preposition and article from previous calling.

Today, I try to study about article "the" which is called by "The definite article".

 

We can use it in front of a noun when we believe the listener/reader knows exactly.

 

1. Already mentioned it.

- I will go to a hospital. The hospital is close with my home.

 

2. There is only one.

- The moon has different phases depending on its relative position with earth and sun.

 

3. If I know it with listner or reader.

- The road, front of our company, will be destroy.

 

Exactly It have more examples, but I'm going to practice thoese three things first. And after I have practiced enough, I will try the following examples.
