If you ... ice in hot water, it melts.

I ... you an answer when I have one.

I'll call you as soon as I ... .

The grass ... wet when it ... .

When you read this email, I ... on a plane to Germany.

If your daughter ... hard, she ... the exam.

If I ... the bus, I ... a taxi.

When I ... too tired to cook, I ... take-out.
