This document discusses the differences between using "going to" and "will" to express future actions, as well as the differences between the present continuous and simple present tenses. It provides examples of sentences using each construction and asks readers to choose the correct form based on whether the future action is planned or instantaneous for "going to" vs "will", and whether an action is scheduled or a habitual activity for the present continuous vs simple present. It aims to help readers properly select between these similar but distinct constructions.
