—Mr Hu, can you tell us how to learn math well? —Sure. But remember nothing can be learned _________ hard work.
—Mom, can I leave my homework for tomorrow? —I’m afraid not. Don’t _________ what you can do today till tomorrow.
_______ you wait a few more minutes? It’ll be your turn soon.
—I called you at 4:00 yesterday afternoon, but no one answered. —Sorry, I ______ with my friends at that time.
You won’t feel happy at school ______ you get on well with your classmates.
