Jeremy Fox, a retired businessman in a small city in England, recently bought an old farmhouse with a yard and a small field, some five miles out of the town. There he planned to lead a simple life with his wife, Amelia.
It was while clearing out the old barn on the far side of the yard that he made an interesting discovery. In a corner, under some old sacks, he found some large fragments (碎片) of an antique (古董) bowl. Out of curiosity, he took them into the kitchen and, much to the anger of his wife, washed the mud off them. That evening he spread newspapers over the kitchen table and carefully stuck the fragments together. However, two pieces were found missing.
Two days later, having pulled down the barn, Mr. Fox was digging over the ground in preparation for the installation (安装) of a greenhouse, when he discovered the two missing pieces. When he had stuck them in position, the bowl looked so fine that Amelia agreed to its being placed on a table in the living room, in front of the window.
“We might have something a bit special here,” he said to his wife. A few days later, Jeremy took several photographs of the bowl, which he sent off to So theby’s in Lond on.
Unexpectedly, Sotheby’s was extremely interested in the bowl and sent an expert to inspect it. It turned out that it was a Chinese Ming fish bowl, dating back to around 1500, and might be expected to get a five-figure sum at an auction(拍卖).
A week later still more unexpectedly, two police officers called and told the Foxes the bowl was stolen property(财产).
So the bowl never reached the auction room, and Mr. Fox never received the five-figure sum that had been mentioned. However, he framed one of the photographs he had taken and hung it on the wall.
24. At first Mrs. Fox seemed to be ________.
A. very much interested in the discovery
B. greatly annoyed at Mr. Fox’s enthusiasm
C. uncertain of Mr. Fox’s enthusiasm
D. curious abo ut Mr. Fox’s find ings
25. The two missing pieces happened to be found ________.
A. in the kitchen
B. in a greenhouse
C. out of the old barn
D. under the ground
26. According to the expert, the bowl could be sold at the price of ________.
A. five thousand pounds
B. less than ten thousand pounds
C. one thousand, five hundred and ninety pounds
D. at least ten thousand pounds
27. Which of the following is NOT TRUE?
A. Most probably Sotheby’s purchased the bowl in the end.
B. It turned out that Mr. Fox got neither the money nor the bowl.
C. Mr. Fox preferred country life to city life after his retirement.
D. Mr. Fox was fond of gardening.
C
With people wearing face masks to protect themselves from being infected ( 感染) with the novel coronavirus (新型冠状病毒), a concern now is how they are dealing with their used masks. As used face masks may carry the coronavirus, they shouldn't be carelessly thrown away as waste. Since the virus can survive for one or two days in wet conditions, the used masks may become a new source of infection.
Given that the garbage sorting（垃圾分类）has recently been carried out in only a few cities, mixed waste commonly exists. The mixture of polluted masks and recyclable waste may cause a possible danger to rubbish collectors when they put hands in the garbage cans to collect recyclable items. What's worse, if someone just throws a used mask on the street, someone might pick it up, or try to collect it to sell second-hand.
With the spread of the novel coronavirus, there has obviously been a high demand for protective equipment such as face masks among ordinary people, with the resulting generation of a huge quantity of what may be considered medical waste. Thus, the problem is how to deal with this mass of medical waste, particularly the used face masks outside of hospitals. Communities should have special trash cans around to collect used masks.If these are not provided, people should put the waste into plastic bags before casting them aside, so they are not exposed to the air.
As the main risk of medical waste is infectivity, disinfection (消毒) , whether by steam, chemicals or microwave, is very important. According to regulations, only licensed（得到许可的）companies should collect, transport and do the final management of medical waste. For example, medical waste must be collected in special containers,and be transported in special vehicles by qualified people.
28. What problem is described in paragraph 1?
A. Used masks may cause infection.
B. Used masks are difficult to recycle.
C. The virus spreads quickly in wet conditions.
D. The novel coronavirus infection is worsening.
29. What is paragraph 2 mainly talking about?
A. The causes of sorting garbage.
B. The ways of recycling used masks.
C. The harm of using second-hand masks.
D. The risk of handling used masks improperly.
30. What do the underlined words "casting them aside" in paragraph 3 probably mean?
A. Destroying rubbish.
B. Throwing waste.
C. Marking rubbish.
D. Reusing waste.
31. What can we infer from the last paragraph?
A. It costs a lot to collect and transport medical waste.
B. The hospital infection is mainly from medical waste.
C. The rules of dealing with medical waste are very strict.
D. License companies should be responsible for infection.
D
Friendship is an important part of human life. Friends can share our joys and sadnesses. We aren't alone. Many different animals also make friends.
Recently, a British research team finished an eight-year study of Indo-Pacific dolphins off the coast of Western Australia. These dolphins can use different tools to search for food. The researchers found that these dolphins are more willing to hang out with partners that like the same tool. Other factors, like family closeness or sex, have no impact on this relationship. It suggests that dolphins form social bonds based on shared interests.
Apart from dolphins, elephants and horses are also known to form friendships. Are friendships only limited to the same species?
Of course not, The Atlantic reported. In 2015,Timur, a goat, was left in the enclosure（围场）of a tiger, Amur, as a meal. But instead of eating Timur, Amur liked to play with him and got angry when others were close to his friend. That's because in captivity(圈养）, animals don't need to spend much time and energy marking their land or looking for mates the way they would in the wild. They are actually more likely to feel bored.
More interestingly, animals not only make friends but also try to keep lasting friendships. Take bats for example. In 2011, scientists found bats often hang out with a few particular friends, keeping loose ties to the rest of their group. Humans are different. "We do not work, play and live together with the same friends all the time," Swiss zoologist Gerald Kerth explained. "But nevertheless, we are able to maintain long-term despite our often highly dynamic（充满活力的）social lives."
32. What do dolphins pay more attention to when making friends?
A. The same interests.
B. Family closeness.
C. Hunting behavior.
D. The special sounds.
33. How can we understand Amur's action?
A. Amur wants to show Timur his land.
B. Amur longs for animals to play with him.
C. Amur has more friends than other tigers.
D. Amur pretends to be friendly to eat Timur.
34. In terms of friendship, what is the difference between humans and bats?
A. Bats usually play with certain friends.
B. Humans keep their friendship longer.
C. Bats like to live together with friends.
D. Humans make friends in social activities.
35. How is the text mainly developed?
A. By listing data.
B. By taking examples.
C. By asking questions.
D. By giving advice.

Ways to Make You a Faster Learner
Are you dreaming of becoming a faster learner? Try the following tips and make progress.
36 Before you can start experimenting with different studying methods, you need to first understand what type of learner you are. This is a really important step.
Use the right tools. 37 There are plenty of websites, online tools and smartphone apps that will help improve your skills in planning, writing and time management.
Train your brain to accept new information. Your brain needs continual training if you want to improve your learning ability. One way to achieve this goal is to create a special learning space in your home. You'll also need a fixed period of time that you'll use to study. 38
Get some exercise. Physical activity is good for your body, and your brain needs it too! 39 If you keep yourself active through light exercise, you will be ready to learn faster.
Take a lot of notes. Only few people are able to remember information as they read it. If you're not one of those people, you completely need to start taking notes. 40 That will help you remember all the other things you've learned.
A. This will make your brain ready to accept the information it gets.
B. Work on the atmosphere（气氛）
C. Examine your learning style.
D. Light exercise, such as yoga, can help you learn much faster.

One possible version:
Film or book, which do you prefer?
Some of us think that it is better to see the film than to read the book in the original. The reason is that it takes less time to understand the whole story. Besides, the film is usually more interesting, and it is easier to follow.
Some others have just the opposite opinion. They think that they can get more detailed information from the original. Meanwhile, the language in the book is possibly more lively and beautiful.
Personally, I agree with the second view. Actually I have more reasons for it. I think I can stay at home, reading quietly in a situation of my own, and what's more, I am able to better understand the author's ideas. In a word, to read the original work is better than to see the film based on it.
银川一中高一期末考试语文试卷 班级＿＿＿姓名＿＿＿学号＿＿ 一、现代文阅读 阅读下面的文字，完成1～3题。（9分，每小题3分） 茶文化源远流长。据传茶的发现约于公元前2700多年的神农时代。最早祖先们利用的是野生茶树，人工栽培约在3000多年前，巴蜀地区是中国茶树的起源地之一。东晋史书《华阳国志·巴志》记载，周武王伐纣时，巴蜀一带已用当地所产茶叶作贡品，说明当时茶叶生产已有一定规模。而后茶的栽培从巴蜀地区南下云贵，东移楚湘，转粤赣闽，入江浙，北移淮河流域，形成广阔的产茶区。 原始社会人类在对植物的长期食用中发现茶树叶有解渴、提神和治疗某些疾病的作用，就把它熬煮成茶水作饮料。长期以来，茶只是用来治病，大约到西周初期，茶叶才发展为茶食，即“生煮羹饭”，后又成为祭品，最终从煮水清饮改进到泡饮。 秦以前，各地语言文字不统一，茶的名称众说纷纭。商周时茶叶首次有了名字，叫“荼”，因其苦涩，又叫“苦荼”。据唐代陆羽《茶经》载，唐以前，茶有“荼”、“贾”等名，自《茶经》问世后，正式将“荼”字减去一横，称之为“茶”。 春秋战国时期，茶叶已传至黄河中下游地区。清代顾炎武在《日知录》中说：“自秦人取蜀而后，始有茗饮之事。”到了汉代，茶的保健作用日益受到重视。西汉王褒在《僮约》中提到“武阳买荼”，说明当时已有了专卖茶叶的茶叶市场。魏晋南北朝时期，饮茶的风气传播到长江中下游，茶叶已成为待客、宴会、祭礼的饮料。南齐武帝临终遗诏说：“灵座上慎勿以牲为祭，惟设饼、茶饮、干饭、酒脯而已。天下贵贱，咸同此制。”从此茶叶成为祭祀时必备的祭品。 唐代中期，饮茶之风盛行全国。各地制茶技术日益提高，出现很多名茶。有关茶的诗歌众多，据统计，李白、杜甫等100多人写了400多篇涉及茶事的诗歌，唐代还首次出现描绘饮茶场面的绘画。宋代，茶成为普及的饮料，特别是上层社会嗜茶成风。制茶的技术达到了精巧奢华的地步，如龙凤团饼茶的制作技术就非常复杂，有蒸茶、榨茶、研茶、造茶、过黄、烘茶等工序。1391年，明太祖下诏“罢造龙团，惟采茶牙以进”。皇室提倡饮用散茶，民间蔚然成风，并将煎煮法改为冲泡法，这是饮茶方法史上的一次革命。明代茶的加工炒制方法和品饮都有了创新，出现了炒青技术和功夫茶艺，从而推动了名茶发展和许多茶类的创新。 茶自发现以后，通过各种渠道传向国外。目前世界上50多个产茶国的茶种、饮茶风尚都来自中国。中国茶叶约在汉代就传入日本，唐代又有大批日本僧人来华，回国时带回茶种。中国茶叶传入欧洲是在1607年。东印度公司成立的第二年，荷兰船首次将茶由澳门转运到爪哇。1669年，英国印度公司把14万磅茶叶运到英国，当时只在伦敦咖啡馆中供应少量中国茶。17世纪初明神宗万历年间，中国大使将少量茶叶运入俄国，大量输入是在1689年签订《尼布楚条约》后，1893年，俄国聘请中国茶工发展茶叶生产。此后中国茶叶又从欧洲和中国传入了东南亚各国。 1. 下列选项与原文意思不相符的一项是（） A. 西周时，作为中国茶树的起源地之一的巴蜀地区的茶叶生产已有一定规模，所产茶叶已作为贡品。 B. 西周初年，茶叶的功用由治病发展为泡饮，其间经历茶食、煮水清饮和祭品三个发展阶段。 C. 西汉时已有了专卖茶叶的茶叶市场，茶的保健作用日益受到重视。 D. 魏晋南北朝时，饮茶的风气已传至长江中下游，茶叶成为祭祀时必备的祭品。 2. 中国茶“通过各种渠道传向国外”，对“各种渠道”表述正确的一项是（）

宁夏银川一中2020-2021学年高二上学期期末英语试题 学校:___________姓名：___________班级：___________考号：___________ 一、阅读选择 My color television has given me nothing but a headache. I was able to buy it a little over a year ago because I had my relatives give me money for my birthday instead of a lot of clothes that wouldn’t fit. I let a salesclerk fool me into buying a discontinued model. I realized this a day later, when I saw newspaper advertisements for the set at seventy-five dollars less than I had paid. The set worked so beautifully when I first got it home that I would keep it on until stations signed off for the night. Fortunately, I didn’t got any channels showing all-night movies or I would never have gotten to bed. Then I started developing a problem with the set that involved static (静电) noise. For some reason, when certain shows switched into a commercial, a loud noise would sound for a few seconds. Gradually, this noise began to appear during a show, and to get rid of it. I had to change to another channel and then change it back. Sometimes this technique would not work, and I had to pick up the set and shake it to remove the sound. I actually began to build up my arm muscles (肌肉) shaking my set. When neither of these methods removed the static noise, I would sit helplessly and wait for the noise to go away. At last I ended up hitting the set with my fist, and it stopped working altogether. My trip to the repair shop cost me $62, and the set is working well now, but I keep expecting more trouble. 1．Why did the author say he was fooled into buying the TV set? A．He got an older model than he had expected. B．He couldn’t return it when it was broken. C．He could have bought it at a lower price. D．He failed to find any movie shows on it. 2．Which of the following can best r eplace the phrase “signed off” in Paragraph 1? A．ended all their programs B．provided fewer channels C．changed to commercials D．showed all-night movies 3．How did the author finally get his TV set working again? A．By shaking and hitting it. B．By turning it on and off. C．By switching channels. D．By having it repaired.

银川一中2020届高二(下)期中考试 英语试卷 第二部分：阅读理解（共两节，满分40分） 第一节：阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。（每小题2分，共计30分） A Books Recommended by TED Speakers A Mathematician’s Apology by G. H. Hardy This is the best book I know about the sh eer beauty of mathematics. Here’s one lovely quote from the book: “A mathematician, like a painter or a poet, is a maker of patterns. If his patterns are more permanent than theirs, it is because they are made with ideas.” —David Brenner (TED Talk: A new weapon in the fight against superbugs) The Future by Nick Montfort This is a short read but a great look at some key future thinkers throughout history. Through delightfully written case studies, Montfort makes the argument that the future can be made and not predicted. It’s a must-read for anyone interested in future studies and the role that sci-fi, speculative design and big ideas play in shaping our future relationship with technology. —Raphael Arar (TED Talk: How we can teach computers to make sense of our emotions) Improv Wisdom: Don’t Prepare, Just Show Up by Patricia Ryan Madson “We all could use a lesson on how to have fun in business and in life. Madson does a wonderful job providing strategies on how to deal with life’s many challenging si tuations by drawing from the maxims of improvisational theater.” —Lisa Dyson (TED Talk: A forgotten Space Age technology could change how we grow food) If You Want to Write: A Book About Art, Independence and Spirit by Brenda Ueland For those who know they have something to express, these stressful times can feel a bit hopeless — it may seem impossible to find the time, skill and energy to create. This is one of the most timeless books on how to regain that hope, and it’s also a delightful read, in and of itself. —Sebastian Wernicke (TED Talk: How to use data to make a hit TV show) 21. What is the topic of the talk given by Raphael Arar? A. A new weapon in the fight against superbugs. B. How we can teach computers to make sense of our emotions. C.
