这句话节选自以下短文（第一段倒数第二句）：
I arrived in the United States on February 6,1966,but I remember my first day here very clearly.My friend was waiting for me when my plane landed at Kennedy Airport at three o’clock in the afternoon.The weather was very cold and it was snowing,but I was too excited to mind.From the airport,my friend and I took a taxi to my hotel.On the way,I saw the skyline of Manhattan for the first time and I stared in astonishment at the famous skyscrapers and their man-made beauty.My friend helped me unpack at the hotel and then left me because he had to go back to work.He promised to return the next day.
Shortly after my friend had left,I went to a restaurant near the hotel to get something to eat.Because I couldn’t speak a word of English,I couldn’t tell the waiter what I wanted.I was very upset and started to make some gestures,but the waiter didn’t understand me.Finally,I ordered the same thing the man at the next table was eating.After dinner,I started to walk along Broadway until I came to Times Square with its movie theatres,neon lights,and huge crowds of people.I did not feel tired,so I continued to walk around the city.I wanted to see everything on my first day.I knew it was impossible,but I wanted to try.
When I returned to the hotel,I was exhausted,but I couldn’t sleep because I kept hearing the fire and police sirens during the night.I lay awake and thought about New York.It was a very big and interesting city with many tall buildings and big cars,and full of noise and busy people.I also decided right then that I had to learn to speak English.
