***** NOT A TEACHER *****
You have written a very interesting paragraph.
I only wanted to make a few suggestions:
1. Please remember that in English, we ALWAYS capitalize the word "I." It does not matter if it starts a sentence or if it is in a sentence.
2. Please remember that "teacher" and "doctor" are not professions. A teacher belongs to the profession of education, and a doctor belongs to the profession of medicine.
3. Please remember that TV is not the only place where journalists work. You may wish to use the word "media" in your paragraph. The media include newspapers, magazines, television, the Internet, etc.
4. Please remember that writing teachers tell us not to write words such as "Now I will try to support my opinion." Just support your opinion, but don't tell your readers that you are going to do it. And when you conclude, don't tell your readers that you are going to conclude.
