His first article, Bird Photography: an Ideal Hobby for Boys, was published when he was just 16 and illustrated with photographs that he’d taken. His interest in photography had been sparked four years earlier in 1930, when the wildlife photographer Cherry Kearton came to Southsea, Ashby’s home town, to present a show of his work. The 12-year-old Ashby saw the show and immediately started saving his pocket money to buy a camera for filming wildlife in the nearby New Forest. But Ashby’s films did not reach the public due to the World War II. In 1953, he and his wife Eileen moved to Badger (獾) Cottage, in the heart of the New Forest. It was here that Ashby perfected the techniques that would make him famous through the new medium of television. His patience and technical knowledge allowed him to film badgers at their holes during daylight — the first time this behaviour had ever been captured on camera. In 1961, at the age of 43, Ashby finally got his big break, when the BBC showed his 45-minute film The Unknown Forest. The film had taken four years to make and received a very positive response from viewers. The nature writer Richard Mabey was hugely impressed and remarked that the film “changed the standards for home-grown wildlife documentaries”. After the film was shown, he was given the nickname “the silent watcher”. The nickname not only stuck, it became the title of his second film. In 1963, Ashby made the first British wildlife film in colour, although it took four years before The Major appeared in its full glory, as the BBC did not broadcast (播放) in colour until 1967. He was awarded the Royal Geographical Society’s Cherry Kearton Medal and Award in 1975 and in 1992 received an MBE. He died, aged 85, on 6 February 2003, but his legacy lives on. 4. What does the underlined word “sparked” mean in Paragraph 2? A Revived. B. Inspired. C. Assessed. D. Increased. 5. What might lead to the success of his 1961 film? A. Unique scenes and the new medium TV. B. Animal knowledge and new standards. C. The positive response from viewers. D. The recommendation from a nature writer. 6. What can be learned from Paragraph 6? A. The Major took Ashby 4 years to make. B. The Major was not broadcast on BBC. C. The Major was another success for Ashby. D. The Major was the first color film in the UK. 7 What can be a suitable title for the text? A. An Award Winner B. A Silent Watcher C. The Life of a Badger D. The Story in a Forest C A new study led by researchers at the Yale School of Public Health finds air pollution may negatively impact standardized test scores. Using data from the North Carolina Education Research Data Center, the researchers tracked 2.8 million public school students in North Carolina from 2001 to 2018 and measured their exposure to PM2.5 found in polluted air. While previous research has shown negative effects on academic performance, it has relied on relatively small or less representative samples. “The biggest strength of this study is that we tracked every student in North Carolina in those years, for the whole time period that they were in the public schools,” said Emma Zang, coauthor of the study. The study also finds that test scores of ethnic minorities and girls are disproportionately (不成比例地) impacted by PM2.5 levels. “Females and ethnic minorities face sexism and racism,” said Zang. “There are a lot of policies that are not friendly towards them. So, when they’re exposed to the same level of air pollution, they don’t have the resources to lessen the negative influences.” More privileged populations, however, might have more resources that allow them to live in a better environment, such as in houses with air purifiers. “The level of PM2.5 pollution in the US is relatively low, but students living in areas below the current air quality standard of annual PM2.5 concentration are still negatively impacted by air pollution when it comes to their test scores,” said Zang. “We should aim to strengthen the annual PM2.5 standard to better protect our children.” Air pollution is known to contribute to disease and death, and it also negatively affects students’ academic performance even at low levels of pollution. The subsequent studies, the researchers said, would involve looking at whether the findings hold true in different areas, and also the reasons behind the ethnic and sexual differences. 8. What’s the greatest advantage of the study? A. Tracking each student for 18 years. B. Collecting more comprehensive data. C. Measuring students’ PM2.5 exposure precisely. D. Building links between air pollution and test scores. 9. According to Zang, ethnic minorities and girls ________. A. benefit from current policies on PM2.5 pollution B. have the lowest test scores due to their identities C. lack resources to reduce the impact of air pollution D. suffer from educational inequalities owing to their background 10. What’s Zang doing in paragraph 3? A. Offering a suggestion. B. Raising a doubt. C. Making a comparison. D. Giving a prediction. 11. What might be the focus of the follow-up studies? A. Applicability of the findings to other regions. B. Ways to address racial and sexual differences. C. Long-term impacts of air pollution on children. D. Establishment of PM2.5 standard fit for children. D Have you ever forgotten items when trying to recall a shopping list? Or dialled the wrong phone number when attempting to memorise one? The brain mechanisms (机制) that cause us to draw a blank in such situations have now been identified. Our working memory keeps small pieces of information that are readily accessible for planning, understanding and solving problems. But it will have “swap errors”. For example, if we are shown a red square and a blue circle, and are then asked what colour the circle was, we might say red. To understand why we make such errors, Jeff Johnston at Columbia University and his colleagues recorded the brain activity of two monkeys because a monkey’s working memory is very similar to humans’. The monkeys were shown two differently coloured squares, one above the other, for half a second. After a short delay, a black spot appeared in the same location as one of the squares, and then disappeared. The animals were trained to tell the colour of the square they were supposed to be remembering based on the location of the spot, by staring at the matching colour on a rotatable (可旋转的) wheel. When doing this for about 3 hours over multiple sessions, the monkeys performed the task correctly between 60 and 82 percent of the time, but occasionally made swap errors. The research suggests that the brain responses linked to swap errors emerged before the animals decided which colour to report. They appeared to arise during “selection” when certain items stored in working memory are enhanced at the expense of others, rather than occurring as a result of them forgetting or a failure to correctly encode (编码) items in their working memory. “Everyone assumed there were simpler explanations like failure to encode or forgetting, but this very cool study shows that working memory errors come from a previously unknown source,” says Earl Miller at the Massachusetts Institute of Technology. The team is planning further experiments to gain a better understanding of mechanisms behind swap errors. 12. What is the function of working memory? A. To identify the errors in understanding. B. To reduce the occurrence of mind blanking. C. To develop the way of distinguishing colours. D. To store information ready for mental use. 13. What were the monkeys tasked with in the research? A. Correcting their errors over multiple sessions. B. Playing a matching game on a rotatable wheel. C. Reporting the colour of the square to memorize. D. Figuring out the exact position of the black spot. 14. What does the research suggest about swap errors? A. They are unusual brain responses. B. They show a tendency for forgetfulness. C. They have an effect on working memory. D. They are the outcome of memory selection. 15. What is Earl Miller’s attitude towards the research findings? A. Unclear. B. Appreciative. C. Objective. D. Negative. 第二节(5小题，每小题2.5分，满分12.5分) 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 It has been shown that watching English movie trailers(预告片) can improve your English vocabulary and thinking skills. ___16___ The first step is to find them.

As he was leaving home, his dad grabbed him by the hand and said, “Before you go, just tell me the directions on where you and your friends are going to stay.” “But dad!” Kevin complained. “No buts!” Kevin’s dad added. “Fine.” Kevin told him the directions and left. The three friends, Kevin, Jay and Nathan, had been planning this adventure for weeks, packing their stuff-tents, snacks, and a map-preparing for a 3-day outdoor exploration. Excitement ran through Kevin as they departed for their campsite. “This trip is going to be awesome, ” Nathan excitedly yelled as they set off. But little did they know that nature had a surprise in store for them. The first day at the campsite was going great setting up tents, collecting firewood, and sharing stories. “Man, we nailed these tents, ” Kevin said. “I know it was easy really,” Nathan replied. The friends were happy. Yet towards night, as the dark clouds gathered overhead, the atmosphere shifted, and a sudden storm erupted with unforgiving anger. Rain poured down from the heavens like a relentless waterfall, transforming the peaceful campsite into a muddy battleground. Worse still, a huge tree was uprooted and crashed down with a deafening crack on their only means of escape - their car. Kevin’s eyes widened in horror as he spotted the damaged wreckage beneath the fallen giant. “Our car!” he screamed over the howling wind, his voice a mix of disbelief and despair. “We’re stuck here,” he declared, his words barely audible against the backdrop of thunder and raindrops. They realized that their plans had been violently spoiled by forces beyond their control. The once quiet campsite now stood as a deserted battlefield, the fallen tree serving as a painful reminder of the unpredictable nature of the world around them. 注意： 1. 续写词数应为150左右；2. 请按如下格式在答题卡的相应位置作答。 Paragraph 1: The next day, they found themselves facing the immediate problem of finding water. _______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Paragraph 2: On the third night, a distant engine sound broke the terrible stillness. _______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 听力1-5CABAB 6-10CBACA 11-15CCBAB 16-20CBABC 绵阳中学2022级高二下期期末模拟 英语试题 第一部分听力(共两节，满分30分) 第一节(共5小题：每小题1.5分，满分7.5分) 听下面5段对话。每段对话后有一个小题，从题中所给的A、B、C三个选项中选出最佳选项，并标在试卷的相应位置。听完每段对话后，你都有10秒钟的时间来回答有关小题和阅读下一小题。每段对话仅读一遍。 1．What will the woman probably do next?

Doing sports on a regular basis has a positive impact on maintaining students’ physical fitness and improving our mental well-being. I strongly recommend everyone to get involved in physical activities. Firstly, we can make good use of the sports facilities at our school to take an active part in various sports, ranging from playing basketball to swimming. Besides, it will be better if we incorporate physical activity into our daily routines such as going to and from school by bike or on foot. Even small efforts can make a great difference in improving our overall fitness. Let’s sweat our way to good health and a more vibrant campus community. Student Union 第二节(满分25分) 【47题答案】 【答案】 Paragraph 1: The next day, they found themselves facing the immediate problem of finding water. The search for water soon drained their energy. They were about to give up when they heard a small sound, a splash of some sort. They ran as fast as they could and found a small stream-a lifeline in all the challenges.  However, with time passing by, more challenges emerged -limited food, frightful night filled with wilderness sounds, and the uncertainty of survival in the wild.  Their nerves were near the edge of breaking down after long hours of uncertainty in the wilderness. Paragraph 2: On the third night, a distant engine sound broke the terrible stillness. Relief washed over the weary faces as they witnessed the approach of a rugged vehicle. Kevin’s dad stepped out to meet the group. The emotions that played across their faces - disbelief, gratitude, and overwhelming joy- mirrored the shared trouble that had forged a deep bond among them. Back home, Kevin’s dad said, “Good thing you told me those directions,” teaching them the importance of informing someone about plans. The experience turned into tales of courage and resilience, embedded in their memories as lessons for a lifetime. 听力1-5CABAB 6-10CBACA 11-15CCBAB 16-20CBABC 第1页/共1页 学科网（北京）股份有限公司 $$
