Il y a de nombreuses fautes. Voici le corrigé :
- I chose to speak about a famous city of the United States of America called New York.
- the Big Apple is the biggest city... majuscule + superlatif et non comparatif
- I went there last summer for one month : pas besoin de mettre 'the' avant last summer
- I went there by airplane, it was a 6-hour flight
- a big building with a lot of students who liked me, came to visit.
- I usually took the subway
- Everybody often takes the taxi
- during this holidays, I shopped a lot.
- because everything is less expensive
- the second thing I loved the most in NY was to eat
