Shawn Triplett, who now works as a volunteer at a local elementary school, was recently helping out at a shelter when he witnessed a damaging interaction between a mom and her young child after they had been displaced by the tornadoes.
"I saw a child crying in his mother's arms. She was crying too, but you could tell she was doing her best to look strong, " he recalls. "The boy told his mom, ‘I've lost my Christmas.' It was at that moment that I broke down and had to walk outside."
After taking a night to think about how he could best help, Triplett decided to ask friends and family to donate money so he could buy toys for the children who were impacted.
"I was going to give them back their Christmas, " he explained. "There was so much support in the community for water, generators and food, but nobody was thinking about the kids. At least, not in the way it should be, so close to Christmas."
Triplett ended up launching a GoFundMe page to help purchase holiday gifts for the children, which quickly spread on social media. Since launching the page three days ago, he had raised over $44, 000. He also partnered with the local supermarket, which provided a 25% discount on all purchases for him.
While the toys were fully covered by the donors, Triplett said he had been footing the bill for wrapping paper. He planned to deliver the gifts in person in a Santa costume closer to Christmas. "We chose to wrap them so that the kids get the full experience of what Christmas should be, " he said. "We're doing everything we can to normalize a traumatic (创伤的) experience for them, even if just for a few hours."

Science reporting on climate change does lead Americans to adopt more accurate beliefs and support government action on the issue, but these gains are fragile, a new study suggests. Researchers found that these accurate beliefs fade quickly when people are exposed to coverage skeptical of climate change.
"It is not the case that the American public does not respond to scientifically informed reporting when they are exposed to it, " said Thomas Wood, associate professor of political science at the Ohio State University. "But even truly accurate science reporting recedes from people's frame of reference very quickly."
Results showed that accurate science reporting didn't persuade only politicians and people who initially rejected human-caused climate change also had their opinions shifted by reading accurate articles. The study involved 2, 898 online participants who participated in four waves of the experiment during the fall of 2020.
In the first wave, they all read authentic articles in the popular media that provided information reflecting the seientifie views on climate change. In the second and third waves, they read either another scientific article, an opinion article that was skeptical of climate science, or an article on an unrelated subjeet. In the fourth wave, the participants simply were asked their beliefs about the science of climate change and their policy attitudes.
To rate participants' scientific understanding. the researchers asked after each wave if they believed that climate change is happening and has a human cause. To measure their attitudes, researchers asked participants if they favored government action on climate change and if they favored renewable energy.
"What we found suggests that people need to hear the same accurate messages about climate change again and again. If they only hear it once, it recedes very quickly, " Wood said. It was significant that accurate reporting had positive effects on all groups, including those who originally rejected climate change. But it was even more encouraging that it affected attitudes.
50．What does the underlined word "recedes" in paragraph 2 mean
A．Increases. B．Graduates. C．Disappears. D．Strikes.
51．What does paragraph 4 mainly tell us
A．The research object. B．The research result.
C．The research purpose. D．The research procedure.
52．Why did researchers ask participants the second question
A．To survey the government's satisfaction rate.
B．To make an assessment on their attitudes.
C．To teach them scientific understanding.
D．To measure action on climate change.
53．What can be the best title for the text
A．Science Report Of Climate Change Can Affect Minds
B．Online Participants Joined In A Four-Wave Experiment
C．Accurate Science Reporting Don't Persuade Only Politicians
D．People Should Hear Accurate Messages About Climate Change
【答案】50．C

One dilemma that the super famous face is balancing the needs of privacy and recognition.
For some stars privacy is an overvalued thing. In 1919, Douglas Fairbanks and Mary Pickford went on their European honeymoon. The two international idols had divorced their previous spouses (配偶)and were concerned about how they would be greeted. They needn't have worried. In London their car was surrounded by admiring women who pulled Mary out of the car to shake her hand, still grateful after two years for her efforts selling war bonds. In Paris they couldn't get any sleep with crowds gathering below their hotel room to sing and play for them. In Amsterdam they attended a party and were mobbed (包围) by other guests who wanted to get close to them. The athletic Fairbanks placed his wife on his shoulder and escaped through the window. Finally, they found privacy in Hamburg, where their movies were not shown because of World War I. For an hour the famous newly-married couple walked the streets unnoticed until the bored Mary turned to her husband and said, "Doug, I'm sick of this. Let's go back to one of those countries where they mob us."
Joan Crawford had similar feelings. Once in the 1930s she was staying in New York getting over her breakup with Clark Gable. Tired of staying around her hotel feeling so down she told her entourage (随从) they should go out and get some fresh air. The entourage, who had trouble keeping up with the star's quick pace, were shocked when she walked away from their planned road. "Oh my God. She's going into Grand Central Station!" Someone shouted, "Look, it's Joan Crawford! And she was mobbed. It took them thirty minutes to escape the crowd and get back to their hotel suite. Her hair disheveled (凌乱), her dress tom and her face scratched, Crawford leaned against the door out of breath. "Oh, oh my. That was wonderful. Let's do it again!"
54．What did Douglas and Mary worry about before going to Europe
A．Nobody would greet them.
B．They wouldn't be welcomed.
C．Their war bonds wouldn't sell well.

54．考查细节理解。根据第二段中的"The two international idols had divorced their previous spouses (配偶) and were concerned about how they would be greeted. "这两位国际偶像已经与前任离婚，他们很担心自己会受到怎样的欢迎。可知，他们在去欧洲之前担心他们不会受到欢迎。故选B。
55．考查推理判断。根据第二段中的"Doug, I'm sick of this. Let's go back to one of those countries where they mob us. "Doug，我受够了。让我们回到那些人们把我们团团围住的国家去吧。可推知，她真的不太喜欢隐私。故选D。
56．考查推理判断。根据第三段中的"That was wonderful. Let's do it again!"这是美妙的。让我们再来一次!可推知，Joan Crawford认为自己在纽约被团团围住是一种享受。故选B。
57．考查推理判断。根据第一段"One dilemma that the super famous face is balancing the needs of privacy and recognition. "超级名人面临的一个难题是如何平衡隐私和知名度的需要；以及下文两个例子可知，文章主要是为了展示电影明星既需要隐私也需要公众关注。故选C。

In habitats across the planet, animals periodically drop everything to walk, fly or swim to a new place. Wildlife such as whales and geese learn migration paths by following their parents. Others, including small songbirds, gain the distance and direction of their migration within their genetic code. And some animals use a combination of genetics and culture to guide their migration.
Another group of migrators does not quite fit either model, and researchers have only recently started to figure out how they find their way. Take the Cory's shearwater, an oceangoing sea bird that migrates over the Atlantic every year. The young do not migrate with their parents, so culture cannot explain their journeys. And the exact paths vary wildly from individual to individual, making genetics equally unlikely.
Cory's shearwaters are long-lived, rarely producing young successfully before age nine. This leaves an opening for learning and practice to develop their migration patterns. Researchers call this the "exploration-refinement", and until now it has been hypothetical (假设的) because of difficulties in tracking migratory animals' movements.
But a team of researchers has done that by attaching small geolocators to more than 150 of the birds aged four to nine. They found that younger birds traveled longer distances, for longer periods, and had more diverse paths than older birds. "We finally have evidence of the 'exploration-refinement' for migratory birds, " says Letizia Campioni, who led the study. Younger Cory's shearwaters are able to fly just as fast as the adults— but they do not, suggesting that the young do more exploring, which gradually fades as they mature and settle into a preferred course.
Although it may seem less efficient than other strategies, "exploration refinement could be beneficial to birds and other organisms in a rapidly changing world due to unpredictable man-made changes," says Barbara Frei. "It might be safer to repeat a behavior that was recently successful than to rely on patterns that were perfected long ago but might no longer be safe."
58．What is the first paragraph mainly about
A．It describes animals' habitats.
B．It talks about migration models.
C．It compares different species.
D．It introduces a tracking technology.
59．What does the underlined word "this" in paragraph 3 refer to
A．The opening for learning and practice.
B．The unique living habit of Cory's shearwaters.
C．The way Cory's shearwaters form their migration patterns.
D．The process scientists track Cory's shearwaters' movements.
60．What does Letizia's study find about the younger Cory's shearwaters
A．They travel as much as adult birds.
B．They move in a predictable manner.
C．They lower the speed for exploration.
D．They look for a course with their parents.
61．What can we conclude from the last paragraph
A．Man-made changes make migration easier.
B．Animals make a safer journey via a fixed track.
C．Course exploration contributes to birds' adaptability.
D．A combination of strategies assures migration success.

【解析】【分析】本文是一篇说明文，介绍了对科里海鸥迁徙的模式的研究。
【点评】本题考点涉及细节理解，代词指代，推理判断和段落大意四个题型的考查，是一篇科研类阅读，通读全文，理解文章大意，阅读题目后返回原文阅读并找出与题目相对应的内容，仔细核对，选择符合原文原意的答案，完成后再次阅读并检查。
58．考查段落大意。根据第一段中的"Wildlife such as whales and geese learn migration paths by following their parents. Others, including small songbirds, gain the distance and direction of their migration within their genetic code. And some animals use a combination of genetics and culture to guide their migration. ”像鲸鱼和大雁这样的野生动物通过跟随父母学习迁徙路线。其他鸟类，包括小型鸣禽，在它们的遗传密码中获得了迁徙的距离和方向。一些动物利用遗传和文化的结合来指导它们的迁移。可知，本段主要讲述动物迁徙的模式。故选B。
59．考查代词指代。根据第三段中的"Cory's shearwaters are long-lived, rarely producing young successfully before age nine. This leaves an opening for learning and practice to develop their migration patterns.”科里海鸥的寿命很长，很少能在九岁之前成功产下幼崽。这为学习和实践发展它们的迁移模式提供了机会；以及"Researchers call this the ‘exploration-refinement’"研究人员称之为"探索-精炼"。可知，此处指研究人员称这种模式为"探索-精炼"，第三段中划线的this指代的是科里海鸥形成迁徙模式的方式。故选C。
60．考查细节理解。根据第四段中的"Younger Cory's shearwaters are able to fly just as fast as the adults— but they do not, suggesting that the young do more exploring, which gradually fades as they mature and settle into a preferred course.”年轻的科里海鸥能够和成年海鸥一样快地飞行，但它们没有，这表明年轻的科里海鸥会进行更多的探索，随着它们成熟并确定了自己喜欢的路线，这种探索逐渐消失。可知，莱蒂齐亚的研究发现小科里海鸥为了探索降低了它们的飞行速度。故选C。
61．考查推理判断。根据最后一段中的"Although it may seem less efficient than other strategies, ‘exploration refinement could be beneficial to birds and other organisms in a rapidly changing world due to unpredictable man-made changes, ’ says Barbara Frei.”芭芭拉·弗雷说："尽管它看起来比其他策略效率低，但在一个由于不可预测的人为变化而迅速变化的世界中，探索精炼可能对鸟类和其他生物有益"。可推知，路线探索有助于鸟类的适应能力。故选C。

A
Shawn Triplett, who now works as a volunteer at a local elementary school, was recently helping out at a shelter when he witnessed a damaging interaction between a mom and her young child after they had been displaced by the tornadoes.
"I saw a child crying in his mother's arms. She was crying too, but you could tell she was doing her best to look strong, " he recalls. "The boy told his mom, ‘I've lost my Christmas.' It was at that moment that I broke down and had to walk outside."
After taking a night to think about how he could best help, Triplett decided to ask friends and family to donate money so he could buy toys for the children who were impacted.
"I was going to give them back their Christmas, " he explained. "There was so much support in the community for water, generators and food, but nobody was thinking about the kids. At least, not in the way it should be, so close to Christmas."
Triplett ended up launching a GoFundMe page to help purchase holiday gifts for the children, which quickly spread on social media. Since launching the page three days ago, he had raised over $44, 000. He also partnered with the local supermarket, which provided a 25% discount on all purchases for him.
While the toys were fully covered by the donors, Triplett said he had been footing the bill for wrapping paper. He planned to deliver the gifts in person in a Santa costume closer to Christmas. "We chose to wrap them so that the kids get the full experience of what Christmas should be, " he said. "We're doing everything we can to normalize a traumatic (创伤的) experience for them, even if just for a few hours."
46．What inspired Triplett to make an effort to help children
A．A mother's demand. B．A volunteer's appeal.
C．A young boy's words. D．His childhood experiences.
47．How would Triplett help the children
A．By purchasing school supplies.
B．By giving them a normal festival.
C．By launching more GoFundMe pages.
D．By sending them necessities of living.
48．What did the local supermarket do for Triplett
A．It did the delivery work for him. B．It provided all the supplies.
C．It offered free wrapping paper. D．It took some money off his cost.
49．What is the main idea of the last paragraph
A．Triplett made full use of the money he got.
B．Triplett ensured the gifts to be more valuable.
C．Triplett tried to make kids have a normal Christmas.
D．Triplett had normalized the traumatic experience for kids.

Science reporting on climate change does lead Americans to adopt more accurate beliefs and support government action on the issue, but these gains are fragile, a new study suggests. Researchers found that these accurate beliefs fade quickly when people are exposed to coverage skeptical of climate change.
"It is not the case that the American public does not respond to scientifically informed reporting when they are exposed to it, " said Thomas Wood, associate professor of political science at the Ohio State University. "But even truly accurate science reporting recedes from people's frame of reference very quickly."
Results showed that accurate science reporting didn't persuade only politicians and people who initially rejected human-caused climate change also had their opinions shifted by reading accurate articles. The study involved 2, 898 online participants who participated in four waves of the experiment during the fall of 2020.
In the first wave, they all read authentic articles in the popular media that provided information reflecting the seientifie views on climate change. In the second and third waves, they read either another scientific article, an opinion article that was skeptical of climate science, or an article on an unrelated subjeet. In the fourth wave, the participants simply were asked their beliefs about the science of climate change and their policy attitudes.
To rate participants' scientific understanding. the researchers asked after each wave if they believed that climate change is happening and has a human cause. To measure their attitudes, researchers asked participants if they favored government action on climate change and if they favored renewable energy.
"What we found suggests that people need to hear the same accurate messages about climate change again and again. If they only hear it once, it recedes very quickly, " Wood said. It was significant that accurate reporting had positive effects on all groups, including those who originally rejected climate change. But it was even more encouraging that it affected attitudes.
50．What does the underlined word "recedes" in paragraph 2 mean
A．Increases. B．Graduates. C．Disappears. D．Strikes.
51．What does paragraph 4 mainly tell us
A．The research object. B．The research result.
C．The research purpose. D．The research procedure.
52．Why did researchers ask participants the second question
A．To survey the government's satisfaction rate.
B．To make an assessment on their attitudes.
C．To teach them scientific understanding.
D．To measure action on climate change.
53．What can be the best title for the text
A．Science Report Of Climate Change Can Affect Minds
B．Online Participants Joined In A Four-Wave Experiment
C．Accurate Science Reporting Don't Persuade Only Politicians
D．People Should Hear Accurate Messages About Climate Change
