The document discusses the use of the verb "will" to express future actions and plans in English. It explains that "will" is used in the affirmative form with a base verb to express certainty about future actions, such as "I will call him tomorrow." "Won't" is the contraction of "will not" and is used in the negative form to express things that will not happen in the future, like "I won't finish it today." Questions using "will" follow the structure of "Will + subject + base verb," as in "Will she come to the restaurant?" The document provides examples to illustrate these uses of "will" and "won't" in different contexts.
