The excitement of waiting for a prey(猎物)and the pride of showing off the kill fascinated me. However, everything changed after that cold morning. Early on that day of the late fall, I set off alone for the woods, packing a gun, a bottle of hot coffee and three thick sandwiches. After finding the fresh deer's tracks in the snow, I settled down behind a little bush. I sat there for about an hour. It was then that I saw him. A deer, a big beautiful deer! There was no cover nearer to him than 30 yards. Surely I couldn't miss! I waited for him to realize I was there. I waited for him to be shocked and run away. But he fooled me completely. He came towards me! He was curious, I suppose, or maybe lie was stupid---how else can you explain it? Well, that deer walked right up to where I was sitting. Then he stopped and looked at me! What happened next is hard to believe, but it's true. And it all seemed quite natural. Just as when a friendly young deer comes near you, I reached up and scratched his head. And he liked to be scratched. In fact, he practically asked for more. Then, I fed him my sandwich! Yes, I know what a deer eats, but that deer ate my sandwich. Well, he finally went his way, down the hill and up the deer trail. Shoot him? Not me. You wouldn't have either, not after that. I just watched him go. When I was about half way back, I heard two shots, followed by a dull slam(撞击)a few seconds later. Those two shots usually mean a kill. I had forgotten there were other hunters that day. Those hunters would never know they could have scratched his head. 21. Why didn't the author kill the deer? A. He preferred to shoot a shy deer. B. He was fooled by the tricky deer. C. He was sympathetic for the deer. D. He was too shocked to shoot the deer. 22. What most probably happened to the deer in the end? A. Other hunters shot the deer to death. B. Other hunters scratched the deer's head too. C. The deer managed to escape from being shot. D. The deer would become friends with the author. 23. What's the best title of this text? A. A Hunting in Late Fall. B. A Lovely Deer. C. The Cruel Killing. D. The Last Hunting. B People have grown taller over the last century, with South Korean women shooting up by more than 20cm on average, and Iranian men gaining 16.5cm. A global study looked at the average height of 18-year-olds in 200 countries 1914 and 2014. The results show that while Swedes were the tallest people in the world in 1914, Dutch men have risen from l2th place to claim top spot with an average height of 182.5cm. Larvian women, meanwhile, rose from 28th place in 1914 to become the tallest in the world a century later, with an average height of 169.8cm. James Bentham, a co-author of the research says the global trend is likely but once you average over whole populations, genetics plays a less key role," he added. But while height has increased around the world, the trend in many countries of north and sub-Saharan Africa causes concern, says Elio Riboli of Imperial College. While height increased in Uganda and Niger during the early 20th century, the trend has reversed in recent years, with height decreasing among 18-year-olds. "One reason for these decreases in height is the economic situation in the 1980s," said Professor Alexander. The nutritional and health problems that followed the policy of structural adjustment, he says, led to many children and teenagers failing to reach their full potential in terms of height. Bentham believes the global trend of increasing height has important implications. "How tall we are now is strongly influenced by the environment we grew up in," he said. "If we give children the best possible start in life now, they will be healthier and more productive for decades to come." 24. What can be learned from Paragraph I? A. The increase in women's height is much bigger than men's in the last century.

Having sensed my impatience with her, Meghan put down the shoes, tugged at my sleeve with her free hands and pleaded using her hard-to-understand baby talk. “No, Meghan,” I said again. “Not now. Go away and leave me alone.” Finally, she left. She made no further attempt to bother me. Then I tried to concentrate on the test paper without interference.Paragraph 2Out of the corner of my eye I could see the little girl sobbing because I didn’t have time for her.wondering if you would care to join me.” Hearing this, she laughed excitedly and began the frantic search for her shoes. I knew I should put aside my work and go right at the moment—while bib-bibs still sparked wonder and while my girl thought that a walk with her father was a gift beyond measure.听力原文:Text 1M: Well, I think maybe you could watch me play basketball tomorrow afternoon.W: I’d love to, but I have to go to the denti st.Text 2W: Which platform does the 4:30 train leave from?M: Platform No. 6.

If your phone and wallet become separated, the alarm will warn you so that you don’t leave it behind. And if your wallet is lost or stolen, the GPS tracker can help you reach it. But perhaps the most unusual feature of the V olterman smart wallet is the built-in front-facing camera. If someone dares to open your wallet without your permission, the little camera will take a picture and send it to your mobile phone. Once your wallet is stolen, you will find it easily by receiving the p icture of the thief. The V olterman is really the world’s most powerful smart wallet. It’s also lightweight and thin, making it perfect for travel. The high-tech wallet comes in three models, with the cheapest cost expected to be $169.。
