1. Prepositions of Time

Prepositions can be used to convey time. EXAMPLES: He said he will be sleeping before five o'clock. Tommy will not be here for an hour yet. Their father will return within a year. Jane has been ill since last Sunday. She promises not to talk to me from tomorrow. Did Julia call you at lunchtime? The boss is always sleepy on Monday mornings. He often builds a snowman in the winter.
