The student is in class.

The child receives a present on her birthday.

The suitcase is full of clothes, so we carry it up the stairs with difficulty.

Instead of the slow elevator we prefer to go up the stairs with the key in our hand.

On Monday there will be a long meeting in the office.

I hold the key in my hand while we go up the stairs.

There is a new document on the screen, and next to it an old file.

A lot of people are walking on the sidewalk, so the child waits in front of the crosswalk.

There is no space in front of the garage now, so I leave the car on the street.

The boy takes a lot of notes in class, because there will be an exam soon.
