自近代科学兴起以，人类见证了科学改造世界的力量，也充分享受到了科学成果带来的社会福祉。

科学发展到今天，已经具备了强大的自主性，如果任其无约束地发展，它的潜在成果既有可能造福人类，也有可能摧毁人类。

如何让科学始终朝着善的方向发展，是今天人类亟须解决的问题，科技伦理的兴起也正是基于这样的时代背景。

科技伦理的目标很明确，即通过有效的规范，保证科学研究的所有环节都处于伦理的规训下，使研究的整个链条都指向追求善的目的。

科技伦理发生作用的空间结构包括政策环境、研究主体、研究手段、研究对象与研究结果等，这个研究链条的每个环节内都存在伦理缝隙。

如果处理不当，就会引发严重的社会问题，科学就会从人类福祉变成人类的噩梦。

科学是探索未知的事业，其本性是喜欢自由的研究氛围。

由此，人们自然会认为，不应该为科学研究附加任何约束，所有这些约束都是研究的障碍。

这种说法在社会上很有市场。

其实，这是一种短见。

哲学家托德·莱肯曾指出：“我们对人类的有限性的焦虑，致使我们设计出更高级的不变的实在，这就是上帝、形式、道德法则。

”也就是说，我们要设计出一个远离我们的完美王国，去应对我们所面对的不确定现实。

道理很简单，任何时代的人的认知都具有时代局限性，总有一些没有预料到的事情出现。

如果是好的倒也无妨；如果是恶的，其影响就很难消除。

而且随着科学研究的深入，这种可能性不是小了，而是变大了。

为此，预先设置一些高于当下实践要求的伦理规范，就可以最大限度地消除未来的不确定性所带来的危害。

2019-2020学年郑州市第十九中学高三英语二模试题及答案

2019-2020学年郑州市第十九中学高三英语二模试题及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）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AThere have been many great painters in the rich history of Chinese art. Here are four of the greatest painters from China.Li Cheng (919—967, Five Dynasties and early Song Dynasty)Li Cheng contributed greatly to one of the golden ages of landscape paintings in world history. During his time, he was considered the best landscape painter ever. He is remembered especially for the winter landscapes he created and for simple compositions of tall, old evergreens set against a dry landscape. Several of his paintings are in thin ink which gives them a foggy appearance.Fan Kuan (990—1020 , Song Dynasty)Fan Kuan began his career by modeling Li Cheng's work but later created his own style, claiming that the only true teacher was nature. His finest workTravelers among Mountains and Streamsis a masterpiece of landscape painting and many future artists turned to it for inspiration.Qi Baishi (1864-1957)One of the greatest contemporary Chinese painters, Qi Baishi is known for not being influenced by Western styles like most painters of his time. He can be considered as the last great traditional painter of China. He painted almost everything from insects to landscapes. He is regarded highly in Chinese art for the freshness that he brought to the familiar types of birds and flowers, insects and grass.Wu Guanzhong (1919—2010)Widely considered as the founder of modern Chinese painting , Wu Guanzhong has painted various aspects of China, like its architecture, plants, animals, people and landscapes. Wu went on to combine Western and Chinese styles to create a unique form of modem art. In 1992, he became the first living Chinese artist whose work was exhibited at the British Museum.1.What do we know about Li Cheng?A.He loved landscape paintings.B.He copied many artists' work.C.His work gained worldwide recognition.D.He was considered as Fan Kuan's teacher.2.What is the main feature of Qi Baishi's paintings?A.They have foggy appearances.B.They lack diversity in the theme.C.They come under Western influence.D.They show advanced traditional painting skills.3.What did the four Chinese painters have in common?A.They were all modern painters.B.They all created landscape paintings.C.They were all impacted by Western art.D.They were all pioneers intraditional art history.BJack was born without eyes. He was very lucky as he grew up having other kittens (young cats) to socialize (交往)with, and was used to people from the moment he was born. However, when it came time to find the kittens homes, no one knew where Jack would end up.That’s when I got an e-mail from my friend. All she asked was “Do you still want one of the kittens? There’s one here with no eyes and no one would like to take him”. Without thinking I told her that I did want the kitten.When we first brought him home, Jack stayed mostly in my room. After about a day he had noissues running around and climbing on everything. At times he gets lost in the house, he’ll stop. But we just call his name and talk to him and it isn’t long before he finds his way back to us.A few weeks after getting Jack, we got a new cat named Bear. Jack and Bear have become best friends. It doesn’t matter that he can’t see. He always knows when Bear is around. He’ll run across the yard straight to Bear and wrap his front legs around his neck in a big hug. They run after each other around and wrestle (摔跤). They’ll lie down in the grass together when tired.Jack is truly an inspiration. I’ve owned lots of kittens in my life, but Jack is the happiest and most playful. He doesn’t feel sorry for himself. He doesn’t need pity. I think Jean, owner of Gumbo, another eyeless cat, said it best when she told me that cats don’t have disabilities; they have adaptability.4. Why did Jack come to the author’s home?A. The author cared for an eyeless cat.B. The author didn’t mind whether he was blind.C. No other young cats kept him company.D. The author’s friend begged the author to take him home.5. Which of the following statements is TRUE?A. Jack often wrestles with Bear indoors.B. Jack likes to play with a new eyeless cat.C. Jack quickly adapts to the new environment.D. Jack is good at talking and playing with people.6. What does the underlined word “issue” in Paragraph 3 mean?A. Trouble.B. Fun.C. Luck.D. Business.7. What does the passage mainly tell us?A. A cat has nine lives.B. All is well that ends well.C. God helps those who help themselves.D. A good beginning makes a good ending.CAvi Loeb, a scientist, believes that we are not alone in the universe. The belief fits withLoeb's alien spaceship theory that at least one alien spaceship might be flying over the orbit of Jupiter, which won the international attention last year.Astronomers inHawaiifound the first known interstellar object in late 2017. It was a bit of light moving so fast past the sun that it could only have come from another star. Almost every astronomer on the planet was trying to figure out how the object, called “Oumuamua” got to our far-away part of the Milky way galaxy. “One possibility is that ‘Oumuamua’ is debris from an advanced technological equipment,” Loeb said. “Technology comes from another solar system just showed up at our door. ”“‘Oumuamua’ is not an alien spaceship,” Paul Sutter, another scientist wrote. He suggested Loeb was seeking publicity. Most scientists think “Oumuamua” is some sort of rock. They think it could be an icy wandering comet.Loeb says that “Oumuamua's” behavior means it can't be a block of rock shaped like a long photo. He thinks it's more likely an object that's very long and thin, perhaps like a long pancake or a ship's sail. Loeb says that if someone shows him evidence thatcontradictshis beliefs, he will immediately give in.Loeb believes himself a truth-teller and risk-taker in an age of very safe, too-quiet scientists. “The worst thing that can happen to me is that I would be relieved of my management duties, and that would give me even more time to focus on science,” Loeb says. He said he wouldn't mind giving up all the titles he had and returning to the Israeli farming village where he grew up.8. What does Loeb say about “Oumuamua”?A. It is an icy comet.B. It looks like a long photo.C. It is actually some sort of rock.D. It may come from another alien civilization.9. What does the underlined word “contradicts” in paragraph 4 probably mean?A.Goes against.B. Relies on.C. Turns to.D. Searches for.10. What do you think of Loeb?A. He is foolish.B. He is unsatisfied with his titles.C. He is a firm believer in scientific truth.D. He is uncertain about his career future.11. What's the best title for the text?A. Have Aliens Paid a Visit in Spaceships?B. Do We Really Know about Space Theory?C. Scientists Are Working on High TechnologyD. Astronomers Are Encouraging Space TravelDScientists at the Massachusetts Institute of Technology (麻省理工学院) have turned spider webs into music——creating an strange soundtrack that could help them better understand how the spiders output their complex creations and even how they communicate.The MIT team worked with Berlin-based artist Tomas Saraceno to take 2D (two-dimensional) laser (激光) scans of a spider web, which were linked together and made into a mathematical model that could recreate the web in 3Din VR (virtual reality). They also worked with MIT’s music department to create the virtual instrument.“Even though the web looks really random (随机)，there actually are a lot of inside structures and you can visualize (可视化) them and you can look at them, but it’s really hard to grasp for the human imagination or human brain to understand all these structural details,” said MIT engineering professor Markus Buehler, who presented the work on Monday at a virtual meeting of the American Chemical Society.Listening to the music while moving through the VR spider web lets you see and hear these structural changes and gives a better idea of how spiders see the world, he told CNN. “Spiders use vibrations (振动) as a way to locate themselves, to communicate with other spiders and so the idea of thinking really like a spider would experience the world was something that was very important to us as spider material scientists,” Buehler said.Spiders are able to build their webs without shelves or supports, so having a better idea of how they work could lead to the development of advanced new 3D printing techniques. “The reason why I did that is I wanted to be able to get information really from the spider world, which is very weird and mysterious,” Buehler explained. In addition to the scientific value, Buehler said the webs are musically interesting and that you can hear the soundsthe spider creates during construction. “It’s unusual and eerie and scary, but finally beautiful.” he described.12. What have MIT scientists done according to the passage?A. They have translated spider webs into sounds.B. They have made a mathematical model to produce webs.C. They have created a soundtrack to catch spiders.D. They have known how spiders communicate.13. What can we know about spider webs from paragraph 3?A. Their structures are beautiful and clear.B. Professor Markus Buehler knows them well.C. The American Chemical Society presents the result.D. They are complex for people to figure it out.14. In which field will the study be helpful?A. virtual realityB. printingC. paintingD. film-making15. What is the main idea of the passage?A. It tells us that the music created by spiders is scary.B. It shows how the researchers carry out the experiment.C. It presents a new and creative way to study spiders.D. It explains why scientists did the experiment.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
