If more people use public transports,
If I were you,
We will help you to do the housework
Woul you change your appearance
If I were 10 years older,
If people did not start wars,
Life on Earth would be impossible
If you throw plastic bags into the sea,
I will be surprised
John and Ann will feel disappointed
the world would be a better place to live.
if you fail the exam.
if nobody comes to their party.
I would travel abroad on my own.
there will be less air pollution.
I would tell him the truth.
the fish may eat them and die.
if we have time.
if you had a chance?
if the Sun stopped shining.
