Because
He was sad because he was sitting alone.
As
He practiced the piano everyday as he prepared for his concert.
When
I like to laugh when my friend tells a funny joke.
That
I was so excited that I was on the screen at the game.
Although
Although it was raining, we went for a walk.
While
We like to listen to music while we are driving.
Before
I read the book before I wrote my book report.
Until
He waited in the rain until the bus picked him up for school.
If
I will watch TV if I get my homework done.
Where
I went to the park where I read all afternoon.
