Grammar review
Every subordinating conjunction here does a specific job, and two conjunctions that seem similar can point to very different meanings.
Reason: because, since
She stayed home because she wasn't feeling well.
Time: before, after, since (meaning "from that point until now")
He called his mother after he landed at the airport.
Contrast: although
Although she practiced every day, she still felt nervous.
Purpose: so that
He spoke slowly so that everyone could understand him.
Condition: if
If you finish your homework, you can watch TV.
Watch out for: since can mean either "because" (reason) or "from a point in time until now," so you have to check which meaning actually fits the sentence. Because and so that are also easy to mix up: because gives the reason something happened, while so that gives the purpose or goal.
