高三英语完形填空中等难度题查看答案及解析
A man walked down the trail on a cold, gray day. He was wearing heavy clothes and fur boots. But he still felt cold and uncomfortable.
The man was on his way to a camp near Henderson Creek. His friends were already there. He expected to reach Henderson Creek by six o’clock that evening. It would be dark by then. His friends would have a fire and hot food ready for him.
A dog walked behind the man. It was a big gray animal, half dog and half wolf. The dog did not like the extreme cold. It knew the weather was too cold to travel.
The man continued to walk down the trail. He came to a frozen stream called Indian Creek. He began to walk on the snow-covered ice. It was a trail that would lead him straight to Henderson Creek and his friends.
As he walked, he looked charily at the ice in front of him. Once, he stopped suddenly, and then walked around a part of the frozen stream. He saw that an underground spring flowed under the ice at that spot. It made the ice thin. If he stepped there, he might break through the ice into a pool of water. To get his boots wet in such cold weather might kill him. His feet would turn to ice quickly. He could freeze to death.
At about twelve o’clock, the man decided to stop to eat his lunch. He took off the glove on his right hand, opened his jacket and shirt, and pulled out his bread and meat. This took less than twenty seconds. Yet, his fingers began to freeze.
He hit his hand against his leg several times until he felt a sharp pain. Then he quickly put his glove on his hand. He made a fire, beginning with small pieces of wood and adding larger ones. He sat on a snow-covered log and ate his lunch. He enjoyed the warm fire for a few minutes. Then he stood up and started walking on the frozen stream again.
A half hour later, at a place where the snow seemed very solid, the ice broke. The man’s feet sank into the water. It was not deep, but his legs got wet to the knees. The man was angry. The accident would delay his arrival at the camp. He would have to build a fire now to dry his clothes and boots.
He walked over to some small trees. They were covered with snow. In their branches were pieces of dry grass and wood left by flood waters earlier in the year. He put several large pieces of wood on the snow, under one of the trees. On top of the wood, he put some grass and dry branches. He pulled off his gloves, took out his matches, and lighted the fire. He fed the young flame with more wood. As the fire grew stronger, he gave it larger pieces of wood.
He worked slowly and carefully. At sixty degrees below zero, a man with wet feet must not fail in his first attempt to build a fire. Fortunately, his fire was beginning to burn more strongly. He sat under the tree and thought of the old men in Fairbanks. The old men had told him that no man should travel alone in the Yukon when the temperature is sixty degrees below zero. Yet here he was. He had had an accident. He was alone. And he had saved himself. He had built a fire.
Those old men were weak, he thought. A real man could travel alone. If a man stayed calm, he would be all right.
1.The man made his way to Henderson Creek to ________.
A.have an unforgettable trip
B.meet with his friends as planned
C.experience the hard life there in person
D.be the first person to travel alone in the Yukon
2.Why did the man choose to walk on a trail with snow-covered ice?
A.Because it was the shortest route.
B.Because the scenery around was wonderful.
C.Because it was a path advised by his friends.
D.Because it was the only way to his destination.
3.After his feet sank into the water the man had to stop for a while in that ________.
A.he had to get some food for physical strength
B.he had to reevaluate the safety of the path
C.it was too cold to go any further
D.he had to dry his clothes and boots
4.What can we infer from the last paragraph?
A.Building a fire in such an extreme condition was not as difficult as expected.
B.The fire successfully guaranteed the man’s safety to his destination at last.
C.The man was proud of his ability to survive in such an extreme condition.
D.The man’s experience proved that the old men in Fairbanks were reliable.

It was a cold winter. The wind blew all night and the snow was blinding. When morning came, my three children and I got up and made our way to the windows. As we looked out the window, we saw that the henhouse was gone. Our three hens had been blown away.
I looked at the emptiness outside. Then I saw all three chickens sat around the edge of a white bucket. How was this violent wind not blowing them into the field beyond? I quickly pulled on long snow pants and heavy winter coat, wrapped a scarf and stuck my feet into very large boots .
I shouted at the wind as it blew. I was alone, save for my children. They stared out the window into the vast white sea of snow, their eyes peeled for any sign of movement. Outside I heard the sound of my boots as I walked against the wind.
The snow circling around me, I steadily made my way to the soft cluck-cluck-cluck sound my hens always made. When I reached them, I saw that their little feet were holding on to the edge of the bucket, heads bent forward and away from the wind. I gently lifted each hen and put it carefully into the warm inside. Then I began the freezing walk back to the small shed directly behind our house. One by one I laid my chickens on the cold floor, and they began to cluck softly.
As I shut the shed doors, my eyes went directly to the window where my children were watching. They jumped up and down cheering, and so did I! I wasn’t some dragon slayer (屠龙者) from a fairy tale. I was simply a mom, but the look on my children’s faces told me that they thought I was a hero mom.
1.Seeing all three chickens sitting around the bucket ,the author felt ______.
A. incredible B. worried
C. shy D. confident
2.How does the author reach the hens ?
A. By searching for the white bucket. B. By wearing protective clothes.
C. By following the sound of the hens. D. By shouting at the henhouse.
3.From the story, we know that _________.
A. the author’s children liked dragon slayers
B. the children watched their mother all the way
C. the author struggled to be a hero
D. the author enjoyed herself in the snow
4.What might be the best title for the text?
A. Weather in extreme. B. Hens in trouble.
C. Kindness in need. D. Hero in the snow.
