First time on italki

Today is my first experience on italki. I think that if I write I will learn more English (improve my English skills). I don't really know how Italki works, but I think that I will gradually learn.

If you are talking about using a website, I would use "on," not "in."

Good job and good luck :)

I would like to :)

Toefl writing independent essay (Number 3)

Please help me correct my mistakes!

Question: If you could study a subject that you have never had the opportunity to study, what would you choose? Explain your choice, using specific reasons and details.

My essay:

If I could study a subject that I have never had the opportunity to study, I would choose medicine to become a doctor. There are many subjects to study and nobody can master all of them. A person has to choose one subject to prepare for his or her future. Although I chose civil engineering and enjoy my carrier as an engineer, but being a doctor was always my dream. I was not able to get that chance.
As a child, I always dreamed that someday I would dress in blue clothes and help patients who needed help, especially my mother. My mother had a heart problem and she always seemed to be in a lot of pain. As I was young and eager to learn more, I asked a lot of questions about why my mother was undergoing so much pain. My father always tried to tell me that the doctors would make sure that my mom would pull through her sickness. This gave me some sense of hope and made me believe that doctors always saved lives. I didn't wish to be the wealthiest and most highly educated doctor the world has ever seen. I just wished that someday with my knowledge I could help my mother and her illness. That's why when I couldn’t pass the exam to go to medical university, my little brother took this exam and passed it 2 year later.
In addition to my mother’s illness, I want to be there to help people. As a doctor you share in people’s darkest and happiest moments. I will be the one whose opinion they trust, whose advice they ask, and the one who can change their life. You can heal people and make them better.
Another reason is that when I study medicine, I can learn many things about the human body, about techniques, treatments, and equipment being used in medicine. How interesting is that!
The gratitude for helping someone through a difficult illness, the honor of being trusted to give advice, and the awe of discovering the human body are things that never grow old. Do you want me to study medicine too?

If you are writing a more formal paper, you might want to avoid contractions (that's to that is) and change second person verbs to third person verbs (you share to one shares). It looks like you have a three point thesis in the conclusion, but the thesis is usually the last sentence of the first paragraph because it introduces your paper. Also, it's best not to ask the reader questions because it seems kind of awkward and off focus. Otherwise, good transitions and sentence structure :)

Personally, I don't like the sound of English and I think that if I didn't speak it natively, it would be hard to learn. I never knew some people liked the sound of it. But yes, I can see where English would be useful in business and to get to speak to people around the world. I think people do tend to use English more when they know they are speaking to a global audience. I guess I always thought they were catering to native English speakers who couldn't speak other languages :/ And I can see where TV would be a motivation for learning English :) There are a lot of great American and British TV shows, and you just can't get the full value without knowing the language. 

And Dorothy, I agree. Our way of learning languages in the United States is awful. I have a great Spanish teacher, but I think the methods we use are definitely more effective for reading than for actually speaking. Also, many of the people in my class hate Spanish and think it is really difficult to understand. Our education system should start teaching languages younger and make them more fun.
