What are some examples subordinating connectives by using it in a sentence?

Basically, subordinating is another way to connect two cases (actions), which already have a connection of meaning. Example: Our art teacher would bring down the grade ifwe didn't hand in the project in time.

In this case, I've used if to connect the actions, via saying that the art teacher would bring down the grade. The teacher would do that only if we didn't hand in the project in time. Other subordinate connectives are when, because etc.
