If I die tomorrow, I will meet my friends.✅ 
If I have a test tomorrow, I will study all night.✅ 
If I have a lot of money, I will share to my people.✅ 
If the weather is good, I will wear a short pants.✅ 

You're doing a beautiful job using the first conditional—it shows you're thinking clearly about cause and effect in English! 🌟 Just a small note: "share it with" sounds more natural, and “shorts” is the correct word instead of “a short pants.” You're expressing your thoughts with honesty and heart, and that’s what makes your English special. Keep going—you’re doing great! 💛
