Conditional Structures: In Case, Even If, Unless

1. Overview: This grammar point involves using "in case," "even if," and "unless" with conditional sentences. These phrases help us express possibilities and conditions in different situations. They show how one action can depend on another. 2. Cases of Usage: Case 1: "In case" + subordinate clause (present tense) is used to show a precaution or preparation for a possible situation. Example: "I will take an umbrella in case it rains." Case 2: "Even if" + first/second conditional is used to indicate that something will happen regardless of a certain condition. Example: "Even if it rains, we will go to the park." Case 3: "Unless" + first/second conditional expresses a condition that must be met for something to happen. Example: "I won't go to the party unless you come with me." 4. Additional Notes: Be careful with the tenses used after these phrases. "In case" requires the present tense for the action that might happen, while "unless" and "even if" can use either the first or second conditional depending on the situation.
