Speaking 1 : An ideal place for studying in
well, I'd definitely go with my bedroom. There are many reasons why I always pick this place for studying. First, the room is bright , I can say it's kind of well-lit with two lamps and two large windows with sunlight passing through them and makes it more airy. second, it's quiet and spacious to put all stuff I need. Besides, there is a small bed, sofa, TV, chair, bookcase, mirror and big poster on the wall.The TV is opposite the sofa so I can watch it or play video games when I sit on the sofa. I also have a big desk for my laptop and notes which is located under one of the windows . This is where I actually sit down and study. I love this room very much and I have made it comfy for my needs. It's a warm cozy place where I can relax and catch up on my studies.

Speaking two: A famous person you admire:
Well, there is a notable number of people who have made major differences in the world. The person I would like to talk about is a popular American boxer and a loving father who brought hope and courage to his country. This inspirational man goes by the name of James J. Braddock . I have chosen this man because I think he is a true hero in my eyes and many others. He is someone who overcame several amazing (thresholds) in life and who can be an inspiration to his country and to the world. I think this man fits my definition perfectly . All in all, my personal connection to James J. Braddock is in his inspiration for what I dream to grow up to be. I hope to maybe someday be a hero myself, maybe not in the same way as this inspirational man, but to inspire the people of this world. this wonderful man showed us to fight for your dreams like he did. He was a great boxer who boxed his way out of darkness and defeat into the realm of immortality.

very good 

"thresholds in life" I would need to do a little research into James J Braddock to see if threshold is the correct word to use. 

However I'm sure it probably is. 

Would you please correct me?

This was very naturally written! Good job! Everything in () is what I added. There were a couple if words that needed capital letters, but overall it sounded very conversational. Let me know if you have any questions regarding my corrections. I hope you have fun learning english!
