Adverbial clauses of reason tell us why things happen. We usually use because, as and since to start adverbial clauses of reason.
We can also put the adverbial clause of reason after the main clause.
Because no one else saw these aliens, I refuse to believe you.
As I like cycling, I am going to North Country Park.
When we put the adverbial clause of reason at the beginning of the sentence, we often separate it from the main clause with a comma (,).
Things to remember
One student should ask a question, and another student should answer the question with because.
