"if-clause"的定义和意义

What is an "if-clause"?

An if-clause is a conditional clause that expresses a condition or situation that must be met for another action or event to occur. It typically begins with the word "if" and outlines a hypothetical scenario. For example, in the sentence "If it rains, we will stay indoors," the phrase "If it rains" is the if-clause, presenting the condition under which the action in the main clause, "we will stay indoors," will take place. If-clauses can be used to express real possibilities, hypothetical situations, or even wishes, and they often play a crucial role in forming conditional sentences. The structure and verb tense used in if-clauses can vary depending on the type of condition being expressed.
