Two weeks ago I had to go to the train station because I was taking a trip to Boston. I decided to take a taxi to the station. There is a bus to the station, but I had a lot of luggage and was in a hurry, so I chose a taxi. I heard the horn(喇叭)of the taxi and hurried out of the house. Excited about my trip, I told the taxi driver I was in a hurry because I had a ticket for a train in only 20 minutes. But I soon began to worry as we hurried through the crowded streets. He drove too fast! We drove across the intersections(十字路口)without stopping for the red lights. We did not stay in our lane, but drove down the middle of the streets. As we turned at the corners, the fast movement of the taxi pushed me into its door. In ten minutes we reached the train station, but I never want to hurry that much again. I was 10 minutes early for the train.
A. Right.
B. Wrong.
C. Doesn’t say.
