Do you (mind, I, close, if) the window?
mind if I close
I can understand you, if you speak slowly.
It will be nice if you can come to the party.
You’ll be cold, if you don’t wear a coat.
What are you going to do if you don’t pass your examinations?
I’m sure they’ll understand if you explain the problem to them.
If I’m late this evening, don’t wait for me.
If I don’t see you tomorrow, I’ll phone you.
Do you mind if i close the door?
If I get up in the morning, I usually drink a cup of coffee.
Have something to eat if you don’t eat now, you’ll be hungry later.
