This document discusses the first conditional and future time clauses. The first conditional describes future events that are likely to happen using the structure "If X happens, Y will happen". Only present tense forms can be used in the if-clause. The word "unless" can be used to mean "if not". An imperative can also be used instead of the will-clause. Examples are provided to illustrate the different structures.
