In act one scene 4 explain Romeo's speech lines 113-120 and in this scene when and where does it take place?
This speech of Romeo's occurs at the end of act 1, scene 4, before Romeo and his friends are due to attend "this night's revels." The only further comment before the end of the scene is from Benvolio, who declares "Beat the drum" to encourage his friends onward.
Romeo fears "some consequence yet hanging in the stars," dramatic irony here foreshadowing the later tragic events of the play; he is concerned that the events of the night will set in motion some series of unfortunate incidents. Specifically, he fears that his own death will be the result of these events, an "untimely death" that will follow a period of "despised life closed in my breast." However, Romeo shakes off his misgivings, saying that his fate is in the hands of God ("he that hath the steerage of my course/direct my sail."
Later, of course, the audience becomes aware that Romeo's prophecy was accurate and that his death will indeed be the outcome of the play, with this last moment of revelry with his friends marking the end of a period in his life.
The lines in question occur at the very end of scene iv, following Mercutio's famous Queen Mab speech and just before the beginning of scene v which is the Capulet's feast.
Following the discussion of dreams, Benvolio reminds Romeo and his friends that time is slipping away from them and, if they do not hurry, they will be late for the party. Romeo contradicts Benvolio and says that he fears they will be too early and he shares his premonition that their attendance at the Capulet's party will set into motion a chain of events that will lead ultimately to his own death. The audience is aware of the accuracy of this foreshadowing from the information we received in the Prologue. However, Romeo--in true Romeo form--ignores his own fears and better judgement and heads to the party anyway.
