Conjunctions as, when

....I was young, there were no houses here.

Chris never goes to the beach with us ... he doesn’t know how to swim.

Nobody spoke .... she came into the room.

... the new park opens, I’ll go there every day.

I went to bed at 9 pm... I had a plane to catch at 6 am.

I am late ... I have missed my bus. 

.... we work together, we can achieve great things

... the music played softly , they danced under the moonlight sky.

... the sun sets, the stars come out to illuminate the night sky

... the rain poured down, she sought shelter under the oak tree.
