Questions 24 -27 are based on the following passage. Living in the city is hard. I was born and raised in Dallas, so l know first-hand about heavytraffic and busy roads. However, when I moved to New York City (NYC), I was not very wellprepared for it. I love NYC, but sometimes I have to escape from the noise, to free my mind fromall the daily worries and to clear my thoughts. However hard and challenging life can be, I stillhave to enjoy the road along the way to success. Everyone needs to take a break from the crazy pace of NYC lifestyle. once in a while. Myfavorite spot to do that is the Van Cortlandt Park, with its long paths where I like to ride on mybike, passing trees and bushes so wild that they make you believe you have escaped the citycompletely and are somewhere in the middle of a real forest. Yesterday I made my weekly escape to the park. Wanting to be closer to nature, I decided notto take the pathway but, instead, go directly through the forest. As I moved through the thickforest, I pushed away the branches that came in my way. It was as if there wasn’t a sign ofcivilization around me at all. The air was still wet from the early morning shower, whileeverywhere, in the open, it had already been very dry and hot. Half an hour later I was at my destination point, the meadow (草地) in the middle of theforest. There were a couple of people already sitting on the grass, picnicking, reading, just lyingdown dreaming. Even though I wasn ’t alone on the meadow this time, I actually enjoyed this fact: I could watch the people merge ( 融合) with nature, in this paradise-like place. 24.
