Explanation: Again, we use the present simple tense in the if-clause (e.g., "if Helen works hard") and the future simple tense in the main clause (e.g., "she will pass her exams").

Explanation: In this case, we use the present simple tense in the if-clause (e.g., "if it rains") and the future simple tense in the main clause (e.g., "we will go into a shop"). The word "se" in the original question seems to be a typo.

Explanation: Lastly, we use the present simple tense in the if-clause (e.g., "if I see Joe tomorrow") and the future simple tense in the main clause (e.g., "I will tell him your news").
