In this unit, I learned how to build a correct sentence. Every basic sentence needs a Subject and a Verb.
Here is what I found important:
The Subject: Who or what the sentence is about.
The Predicate: What the subject is or does (contains the verb).
Examples from my practice:
"The student studies."
Subject: The student
Verb: studies
"English is very interesting."
Subject: English
Predicate: is very interesting
