I will drive you home 
when I finish my work.

I was doing my 
homework as my mother 
was cooking.

He bumped into me as I 
was going out of the 
post office.

While he was doing the 
washing, I was ironing.

I learnt some interesting 
facts while I was 
listening to a BBC 
programme.

Take off your shoes 
before you enter the 
house!

Children wash their 
hands before they have 
dinner.

My husband had 
reserved a table before 
we went to the 
restaurant.

You can go home after 
you have written the 
test.

She took a shower after 
she had come home.

I wrote my essay after I 
did some research.

I have been very happy 
since we started dating.

She has been studying 
hard since she went to 
university.

My mother must stay at 
work until she finishes 
the project.

I will not go out until I 
have finished the 
housework.

We are going to stay in 
the mountains till the 
summer ends.

He visits his parents 
whenever he is in town.

You can borrow my pen 
as long as you give it 
back.

You may stay with us as 
long as you behave well.

By the time the police 
got there, the thief had 
run away.

By the time you come 
home, I will have cooked 
dinner.

By the time he told her 
the news, she had 
already known.

Call me as soon as you 
get off the train.

I will write to you as 
soon as I know the 
results.

The moment that my 
dog notices a postman, 
it starts barking.

He jumped out of the 
bed the moment that he 
woke up.

We will go home once 
the party is over.

It is the first time I have 
ever tried beer.

That was the third time I 
had ridden a horse.

This is the last time I will 
help you.
