There ....... some cars in the city last Monday.

There .... a traffic yesterday.

There .... two cats in my cousin's bedroom this morning, but now they are gone.

There (not) ...... any supermarket around here when I was kid.

There ... many bottles of milk in the fridge last night.

There .... an old man in the street.

There .... a cinema around here because this place was too quiet.

There ... only one pen on my desk, but now I don't know where it is.
