Hi, I'm French, can you check my faults in my text please ? Good evening!
First, I would like to thank the organizers for this wonderful evening, also you for your presence and interest.

Humans’ quest has always been to go faster, to go farther, and to conquer new territories. Our history bears so many extraordinary examples of what we have been able to achieve, including going to the Moon! Yet, going to Mars seemed to be the ultimate unreachable goal.

Good evening!

First, I would like to thank everybody for being present and showing intrest.

Though, who would be disinterested? Who has not dreamt about coming one day face to face with a Martian? Well, tonight, your dream has come true! However, you may be disappointed that this incredible adventure did not turn us into little green creatures

Our quest as Humans' has always been to go faster, to go farther, and to conquer new territories. Our history bears so many extraordinary examples of what we have been able to achieve, including going to the Moon! Yet, going to Mars seemed to be the ultimate unreachable goal. It was tiring, yes, to survive in off-terrestrial conditions. And without my experiences in space, I would not be able to walk right now.

But this priceless journey has given our nation an invaluable title! As the commander of Ares 1, I cannot begin to tell you how honored to have been part of it and how proud I am to have planted the flag of our dear America on Mars!

Thank you.

Overall Preformance:

I would rate the original paragraph a 9.5/10. The sentence forming was great and the vocab was great. I loved the speech. The one minor problem I found was that it was missing a few key words, like that, or, and and.

How to improve:

I was new to the english language and now i consider myself pretty good!  I would highly recommend that you practice rewording. For example instead of "Humans’ quest has always been to go faster, to go farther, and to conquer new territories. "  I would start with our quest as humans. This is because we are humans living on planet Earth. When you did not, it sounded like you were from another land. Also, I would recommend to refresh your brain on the concepts of perspective.

I really hope that this helps!

You did a Great Job!
