every day, the bus arrives every thirty minutes

Before reviewing all the materials for the final exam late at night

the phone rang during the lecture

the children played in the park

And forgot to submit the assignment before the deadline

After practicing speaking English with classmates for several hours

On top of the tall building across from the university campus

the dog barked loudly at the stranger

To learn new vocabulary words by reading articles and watching videos

He reads many books every semester for his literature class
