If I were a millionaire $$$$$$$$$$

If I were a millionaire, first, I would buy a big house because I want to live in a mansion like the rich people in the movie. Then, I would make three rooms for my child: for studying, for playing and for sleeping. I would buy a lot of beautiful clothes for my whole family. Lastly, I would use the money for healthy and yummy food.
For the society, I would use lots of money. I would use them for poor people, for paying tax and for studying. I would give the half of my money to the society and I would make sure that everyone can study with good teachers.
I would make sure that I am not the only rich person. I would make everyone in the world happy and smart. Then they would also become rich. If everyone thinks like me, everyone will be happy.☻☻☻☻☻☻☻☻☻☻☻☻☻

Explanation: The conditional sentence Type 2 is used for unreal impossible or improbable situations. This conditional provides an imaginary result for a given situation. It is very unlikely that the condition will be fulfilled. The form is if + simple past, + would + base verb. That's why am and will are changed to were and would. Be careful of word spelling. It should be buy not by.

Julie: Then I will make three rooms each for my child. One for studying, the other for playing and the last for sleeping.
Correct: Then, I would make three rooms for my child: for studying, for playing and for sleeping.
Explanation: Since you three rooms are mentioned, no need to say one, the other or last. Use colon (:) before a list, an example, an explanation, etc.
