11. If it had not been for Fan Jinshi and her team, the world cultural heritage(遗产) at Dunhuang Mogao Grottoes in a remote Chinese desert might have long been destroyed by sand, weather or humans.
Fan has spent more than half a century fighting an uphill battle to preserve the ancient Buddhist wall paintings at Dunhuang, in Northwest China's Gansu Province. Dunhuang Mogao Grottoes are a huge collection of Buddhist art—more than 2,000 Buddha figures and 45,000 square meters of paintings spread among 735 caves. It is one of China's UNESCO World Heritage Sites.
Archaeologist Fan was sent to Dunhuang after graduating from Peking University in 1963. While in Dunhuang, a remote village in the desert then, Fan lived in an abandoned temple. At first, she did not even dare to go out to the toilet at night. To protect the treasures from sand and dampness, Fan and other workers put doors on the caves, planted trees and started monitoring temperature and humidity(湿度) in the caves. They also controlled the number of visitors.
In the late 1990s, with tourism booming nationwide since national holidays were extended, the local government planned to go public with Dunhuang Mogao Grottoes, but found Fan firmly in their way. "The heritage would have been destroyed if it had been listed," she said.
Dunhuang Academy has now photographed and catalogued online all the sculptures and paintings. "Despite our efforts to minimize damage, we can't completely stop them from being eroded(腐蚀). But the digital database will last."
Fan was grateful when her husband joined her in Dunhuang in 1986 after 19 years of separation. Her two sons grew up in Shanghai with their aunt. "I have not been a good mother or wife. With regard to my family, I'm full of guilt," she said. Fan, 81, retired four years ago as the director of Dunhuang Academy but continues her efforts as an honorary president of Dunhuang Academy.
1. Which of the following measures didn't Fan Jinshi take to protect Dunhuang Mogao Grottoes
A. Opening Dunhuang Mogao Grottoes to the public extensively.
B. Planting trees and stopping Dunhuang Mogao Grottoes being eroded.
C. Picturing and classifying all the sculptures and paintings online.
D. Putting doors on the caves and monitoring temperature and humidity.
2. When was Fan separated from her husband
A. In 1963. B. In 1967. C. In 1986. D. In the late 1990s.
3. What kind of person do you think Fan is
A. Considerate and easy-going. B. Kind and intelligent.
C. Humorous and sweet-tempered. D. Committed and persistent.
12. Every summer, my family and I visit our relatives in India and whenever we travel, my parents always remind me to drink only bottled or boiled water. On one of my trips to India, I saw children drinking water from the roadside. I was troubled to learn that millions of people, most of them children in developing countries, die each year because of water-related diseases.
Living in the US, I am lucky to be able to turn on the tap and get potable water (饮用水), while one sixth of the world's population lacks access to clean water. This year, I entered the Discovery Education 3M Young Scientist Challenge. In late June, I learnt that I was selected as one of the top 10 national finalists of this famous middle school science competition. Over the summer, I worked with Dr Jim Jonza, my scientist mentor (导师) from 3M, and developed a system that uses solar energy to purify water. My invention is green and cost-effective, and I am looking forward to implementing this in places that are affected by harmful water pollution.
In October, my family and I flew to 3M headquarters in St Paul, Minnesota, where the final event was to be held. For the last challenge, each of us had to present the invention we had been working on over the summer. The first place winner would win $25,000, a trip to Costa Rica, and the title of America's Top Young Scientist. At the awards ceremony, all of us waited anxiously until one of the judges, Danny Forester, started announcing "The winner, he Discovery Education 3M Young Scientist Challenge is..." You could hear a pin (大头针) drop as he opened the paper with the winner's name, "Deepika Kurup!"
As America's Top Young Scientist. I was given an opportunities to show my invention on national television and deliver several presentations. One of the most important things I have learnt is that communication and teamwork are key to success.
1.Why does the author mention her visits to India
A.To express her great love for India. B.To show the problem of unclean water.

A.Researching. B.Changing. C.Finishing. D.Using.
3.How did the audience react as Forester opened the paper with the winner's name
A.They appeared calm. B.They let out shouts of joy.
C.They sat quietly. D.They dropped pins to the author.
4.How is the text mainly organised

C.In order of place. D.In order of importance.

11. The Nobel Prize in Literature, which has been awarded almost every year since 1901, nets(净赚) the winning author 747,000 pounds($915,000), a medal, a certificate, and the legal duty to deliver a lecture in Sweden at some future date. The winner was selected, as usual, by the Swedish Academy, which also picked a second laureate (获奖者) this year to make up for the fact that no prize was presented in 2018 because of a scandal(丑闻).
The Nobel Prize in Literature for 2018 was awarded to the Polish author Olga Tokarczuk "for a narrative imagination that with encyclopedic(百科全书式的) passion represents the crossing of boundaries as a form of life". She won last year's Man Booker International Prize for her novel Flights. Her representative works include Drive Your Plow Over the Bones of the Dead and Primeval and Other Times.
The Nobel Prize in Literature for 2019 was awarded to the Austrian author Peter Handke "for an influential work that with linguistic ingenuity(语言的独创性) has explored the periphery and the specificity of human experience". His representative works include A Sorrow Beyond Dreams, Slow Homecoming and The Great Fall.
Before the announcement of the Nobel Prize in Literature winners, there were also two nominees(被提名者) who had attracted much attention. Chinese people were keeping their eyes on nominee Can Xue. Can Xue, whose real name is Deng Xiaohua, was born in central China's Hunan Province in 1953. She had a tough childhood, working as a worker in a street factory for eight years. Her life experience has formed her own unique literary path. Can's books have been translated and published outside China. Frontier, published in the US in 2017, won attention and applause from the West.
The other hot guess was Japanese writer Haruki Murakami, whose books and stories have been bestsellers in Japan as well as internationally, with his works being translated into 50 languages and selling millions of copies outside his native country. His works have received numerous awards. Internet users kept eyes on him for the Nobel Prize in Literature because he had become a hot guess for years. His representative works include Norwegian Wood, Kafka on the Shore and 1Q84.
1.Why were two writers awarded the Nobel Prize in Literature this year
A.To fill the prize gap of 2018. B.To attract more people's attention.
C.To inspire more outstanding writers. D.To satisfy the development of literature.
2.What made Olga Tokarczuk win the Nobel Prize in Literature
A.Her high popularity. B.Her language skills.
C.Her numerous works. D.Her writing style.
3.Which book can you choose if you are interested in Peter Handke's style
A.Flights. B.The Great Fall. C.Frontier. D.Kafka on the Shore.
4.Why did the Internet users pay close attention to Haruki Murakami
A.He had created hundreds of great novels.
B.He had received lots of awards all the time.
C.He had been supposed to win the prize for years.
D.He had been recognized as the most popular writer.
12. For years, Hamzeh AlMaaytah supported a community of book lovers in Jordan, keeping his bookstore in Amman's old center open around the clock, encouraging customers to stay for a long time over rare treasures and often allowing them to set the price for a purchase.
His supporters recently had a chance to repay him when the local landmark was threatened with closure, following a sudden illness that put him out of action for several months as bills were piling up. By April, 330 people from more than 20 countries had contributed $18,000 in a crowd-finding (众筹)campaign launched by two friends.
The money allows AlMaaytah to repair his small space and expand to a storefront next to it, where he hopes to set up a literary salon, a display of rare books and a reading comer. Up to now, much of the store's activity has taken place outdoors, with books laid out under a sheet on the sidewalk.
Despite the recent financial scare, the 36-year-old shopkeeper is sticking to his "pay as you please" business model, applied to most books. Customers can also pay a small amount of fee to borrow books or read rare editions in the store.
"It's risky. But it's also an adventure." said AlMaaytah. "You would be surprised what putting your trust in people can do. It doesn't just make more room for generosity. They also want to come back for more. More books, more conversations."
AlMaaytah recently renamed his branch "Mahall al-Maa" loosely translated as "Source of Water." to reflect his belief that books—like water—are a necessity and should be accessible to all.
Such access has been a problem in Jordan, which lacks government-funded community libraries, forcing readers to buy expensive books or go to university libraries, said Sara Qudah, the culture editor of the Al-Rai newspaper.
(1).What did AlMaaytah advise people to do according to Paragraph 1
A.To work hard for good pay. B.To keep valuable jewelry.
C.To enjoy some rare books. D.To go to look for treasures.
(2).What did people do to repay AlMaaytah
A.People donated some money to him. B.People paid almost all his bills.
C.People decorated his bookstore for him. D.People launched crowd-funding campaigns.
(3).Why has much of the store's activity been held outdoors
A.There is a reading comer outdoors. B.All the books are put outdoors now.
C.The store tries to attract customers. D.The store is small.
(4).Which of the following statements does AlMaaytah agreewith
A.People want to be put your trust in wherever they live.
B.Books are a must and all should have access to them.
C.More room should be made for people to show generosity.
D.People want to read more books and make more conversations.
答案以及解析

2.答案：consequence
解析：考查名词。句意：因此，北极熊的数量越来越少。名词consequence作宾语，as a consequence(因此）。故填consequence。
3.答案：gentlest
解析：考查形容词的最高级，句意：他是我所认识的最绅士的人。分析句意再根据空格前的the可知，此处用用the+形容词的高级表示"最绅士"的人，符合语境。故填gentlest。
4.答案：numerous
解析：考查形容词。句意：作为一个积极的社会主义者，他有许多会议和社会活动要参加。设空处在句中修饰后面的名词meetings，作定语，故应用形容词；结合句意及提示词可知，此处应填numerous,表示"许多的：众多的"。故填numerous。
5.答案：gradually
解析：考查副词。句意：在复杂的化学反应后，气体渐渐地转变成了液体。根据句子分析可知，此处修饰动词短语turn into，应用副词修饰。故填gradually。
6.答案：open up a new world before me
7.答案：Even though he was bigger
8.答案： if necessary
9.答案：defending the peace

解析：1.细节理解题。根据第一段最后一句The winner was selected, as usual, by the Swedish Academy, which also picked a second laureate(获奖者) this year to make up for the fact that no prize was presented in 2018 because of a scandal(丑闻).可知,瑞典文学院2019年还选出了第二名获奖者,以弥补在2018年由于丑闻没有颁奖这一事实。故选A。
2.推理判断题。根据第二段第一句The Nobel Prize in Literature for 2018 was awarded to the Polish author Oiga Tokarczuk "for a narrative imagination that with encyclopedic百科全书式的) passion represents the crossing of boundaries as a form of life".可知,"叙事富于百科全书式的激情和想象力,代表了一种跨越边界的生命形式"是这位作家的写作风格,也就是说她的写作风格使她赢得了这个奖。故选D。
3.细节理解题。根据题干中的Peter Handke可以定位到第三段,再根据该段最后一句His representative works include A Sorrow Beyond Dreams, Slow Homecoming and The Great Fall.可知,The Great Fall是彼得·汉德克的代表作之一,如果对他的风格感兴趣可以看这本书。故选B。
4.细节理解题。根据最后一段倒数第二句Internet users kept eyes on him for the Nobel Prize in Literature because he had become a hot guess for years.可知,互联网用户关注着村上春树是因为多年来他都是这个奖的热门人选,这说明多年来大家都以为他会获得这个奖。故选C。
12.答案：(1)-(3)CADB
解析：(1).细节理解题。根据第一段中的"...encouraging customers to stay for a long time over rare treasures and often allowing them to set the price for a purchase."可知,他鼓励顾客在稀有书籍前驻足,允许他们确定购买价格。故选C。
(2).细节理解题。根据第二段第二句" By April,330 people from more than 20 countries had contributed $18,000 in a crow- funding campaign launched by two friends."可知,为了回报他,人们给他捐款。故选A。
(3).推理判断题。根据第三段的第一句" The money allows AlMaaytah to repair his small space and expand to a storefront next to it..."可知,阿勒迈塔想用这笔资金翻修狭小、拥挤的书店。由此可推断出,书店的大部分活动都在室外进行的原因是书店狭小拥挤,故D项正确。故选D。
(4).细节理解题。根据第六段的"...to reflect his belief that books—like water—are a necessity and should be accessible to all."可知,B项正确。故选B。
