As soon as the sun sets, the stars begin to appear in the night sky.When the alarm clock rings, it's time to get out of bed and start the day.After the rain stops, we can go outside and enjoy the fresh air.I will wait until my friend arrives before we start watching the movie.Then, we can all sit down and have dinner together as a family.As soon as the bell rings, it's time to change classes and head to the next one.When the temperature drops, it's a sign that winter is approaching.After we finish our work, we can relax and unwind for the evening.I will wait until the traffic clears before attempting to cross the street.Then, we can make a plan for the weekend and decide what activities to do.
