Give yourself a test. Which way is the wind blowing? How many kinds of wildflowers can be seen from your front door? If your awareness is as sharp as it could be, you’ll have no trouble answering these questions.
Most of us observed much more as children than we do as adults. A child’s day is filled with fascination, newness and wonder. Curiosity gave us all a natural awareness. But distinctions that were sharp to us as children become unclear; we are numb(麻木的) to new stimulation(刺激), new ideas. Relearning the art of seeing the world around us is quite simple, although it takes practice and requires breaking some bad habits.
The first step in awakening senses is to stop predicting what we are going to see and feel before it occurs. This blocks awareness. One chilly night when I was hiking in the Rocky Mountains with some students, I mentioned that we were going to cross a mountain stream. The students began complaining about how cold it would be. We reached the stream, and they unwillingly walked ahead. They were almost knee-deep when they realized it was a hot spring. Later they all admitted they’d felt cold water at first.
Another block to awareness is the obsession(痴迷) many of us have with naming things. I saw bird watchers who spotted a bird, immediately looked it up in field guides, and said, a \They no longer paid attention to the bird and never learned what it was doing.zxxk
The pressures of \and \are further blocks to awareness. I encountered many hikers who were headed to a distant camp-ground with just enough time to get there before dark. It seldom occurred to them to wander a bit, to take a moment to see what’s around them. I asked them what they’d seen. \said. They seemed bent on their destinations.
Nature seems to unfold to people who watch and wait. Next time you take a walk, no matter where it is, take in all the sights, sounds and sensations. Wander in this frame of mind and you will open a new dimension to your life.
51. According to Paragraph 2, compared with adults, children are more _____________.
A. anxious to do wonders B. sensitive to others’ feelings C. likely to develop unpleasant habits D. eager to explore the world around them 52. What idea does the author convey in Paragraph 3?
A. To avoid jumping to conclusions. B. To stop complaining all the time. C. To follow the teacher’s advice. D. To admit mistakes honestly.
53. The bird watchers’ behavior shows that they ____________.
A. are very patient in their observation B. are really fascinated by nature C. care only about the names of birds
D. question the accuracy of the field guides
54. Why do the hikers take no notice of the surroundings during the journey?
A. The natural beauty isn’t attractive to them. B. They focus on arriving at the camp in time. C. The forest in the dark is dangerous for them. D. They are keen to see rare birds at the destination.
55. In the passage, the author intends to tell us we should __________.
A. fill our senses to feel the wonders of the world B. get rid of some bad habits in our daily life C. open our mind to new things and ideas D. try our best to protect nature 绝密★启用前

Some people live to climb the highest mountains. Some people live only dreaming about it while others live to avoid ever climbing at all. But one thing is certain, all people encounter mountains in their life.
When I was a little girl, my family moved to a tiny town at the bottom of a big mountain. One day after school, while exploring the green woods of this magnificent mountain, I almost fell on a set of stairs. What could these steps lead to? Curiosity got the best of me as I knew it would be starting to get dark soon. I started climbing up those strangely mysterious steps.
I climbed and climbed. There was nothing but just green bushes and these steps. I had to reach the top! But it
was now getting real dark. If I kept going I might not be able to see my way back. My mum would be worried sick if I didn’t come home soon. So I ran back home almost in the dark while trying not to get too scared.
Anxiously I went to bed dreaming about what I would find at the top of this magical mountain. Could there be a castle up there? Maybe I would find a monster(怪物). Maybe I was taking the risk of never coming back home. Or, maybe all I would find was absolutely nothing! But something inside me was going to climb that mountain at all cost. I could hardly wait to try this adventure again.
Now we live in a world surrounded by the \do\ attitudes. We all fall down. We all have doubts and regrets. Still we must climb and dream about what’s at the top of our mountain. Monsters may appear or the night will fall. But never ever give up on your dream! Never let anyone tell you, \.\56. What made the author start to climb up the stairs to the mountain top?
