    I as well as my parents are going to New York City this month. I had been looking forward to visit there for a long time. It is one of the most beautiful cities all over the world. There are many places of interests where you can learn it in school. I'd also like to see the Empire State Building.

I am sure it will be an unforgettable experience.
