---I argued with my best friend yesterday and I don’t know what to do now. ---Maybe you _______ say sorry to her.
Don’t shout at him. He _______.
—Don’t do that again. Shame on you! —_______
—Would you mind _______here? —I’m sorry about that. I’ll go somewhere else.
—Would you like to climb mountains with me this Sunday? —I’d love to. But I _______ play table tennis against Class Three.
I think _______ our duty to keep our environment clean and tidy.
