Picture this: You’re searching the Internet and come across a website with interesting articles. Some are news stories. Their goal is to share information. Others only look like news stories. They’re actually advertisements, or ads. The goal of an ad is to get you to buy something. How do you, the reader, tell the difference between a news story and an ad?

Back when I was growing up, it was easier. We got most of our information from newspapers. Big news stories appeared on the front page, and ads were boxed off and clearly labeled. But on the Internet, the two are often presented together. It can be hard to tell which is which.

That’s why the research group I direct conducted a study. My research team showed kids like you the home page of a popular digital magazine. We asked them to tell us what was a news story and what was an ad.

Most were great at identifying certain types of ads. “It has a coupon (优惠券) code, a big company logo, and the words ‘limited time offer’,” one student wrote about an ad on the site. So where did kids get stumped (难倒)?

Some ads seem identical to real news stories. They have headlines and contain information. But they may also include the words “sponsored content”. Sponsored means “paid for,” and content refers to the information in the story. “Sponsored content” is a way of saying that something is an ad. Most kids in our study, even if they used the Internet often, didn’t know

this.

Something sponsore d doesn’t necessarily mean it’s false. It means someone paid money for it to appear. Companies pay so that readers will see their stories, buy their products, and like what the company stands for.

As a reader, you have a right to know who’s behind the information you’re consuming. So, look for the phrase sponsored content. (And look carefully. Sometimes, it will be written in tiny letters.) The Internet is a vast sea of information. To use it well, we not only have to know how to swim but also how to avoid the sharks.

54.Why was it easier for the author to distinguish ads from news stories?

A.Because news stories were clearly labeled.

B.Because ads had a very big company logo.

C.Because ads were printed on separate sections.

D.Because news stories appeared on the front page.

55.The underlined word “shark” in the last paragraph refers to .

A.tricky advertisements B.information consumers C.underwater rocks. D.content sponsors

56.Which would be the best title for this passage?

A.Identify News Stories B.Be digital smart.

C.Research into the Internet D.Be a smart advertiser

Sweet potato plants don't have spines or poisons to defend themselves. But some have evolved a clever way to let hungry herbivores (食草动物) know they aren't an all-you-can-eat buffet, a new study finds. When one leaf injured, it produces a chemical that warms the rest of the plant and its neighbors to make themselves inedible (不宜食用的)to bugs. Sweet potato breeders could potentially engineer plants to produce the chemical as an all-natural pest defense.

Plant ecologists led by Axel Mithofer of the Max Planck Institute for Chemical Ecology in Jena, Germany, started to look into sweet potato (Ipomoea batatas) defenses after they noticed something interesting about two varieties of the plant grown in Taiwan: The yellow-skinned, yellow-fleshed Tainong 57 is generally herbivore-resistant, but its darker orange cousin, Tainong 66, is plagued (造成麻烦) by insect pests.

To find out why, the team offered up Tainong 57 and 66 plants to hungry African cotton

leafworm caterpillars (毛虫).Both plants released at least 40 airborne compounds as the caterpillars snacked on their leaves. But Tainong 57 produced a lot more of a chemical called DMNT, which has a very distinct smell, the team details this month in Scienti fic Reports. (“The smell is not nice,” Mithofer says. “You wouldn't want it as a perfume.”)

DMNT isn't a new compound; researchers have isolated (分离出) the smelly chemical from other plants such as corn and cabbage, and it is known to induce defense responses in some species.

To determine whether this was happening in sweet potatoes, scientists set up two experiments. First, they put two plants next to each other and wounded one so it produced DMNT. Then, they exposed healthy Tainong 57 plants to DMNT they had synthesized (合成).In both cases, the DMNT caused the exposed plants to produce more of a protein called sporamin in their leaves. (Tainong 66 did not have the same reaction.) When the caterpillar’s snack on sporamin, “they immediately stop eating because they don't feel well,” Mithofer says.

Sporamin is the main protein in sweet potato tubers (块茎),and is indigestible raw, which is why sweet potatoes must be cooked for humans to enjoy them. “If the caterpillars could cook it, they could eat it,” Mit hofer says. Theoretically, he says, sweet potato breeders could use genetic engineering to make different varieties of sweet potato produce as much DMNT as Tainong 57, and display the same defense responses.

Still, the research isn't ready for prime time, cautions plant ecologist Martin Heil. DMNT might work in the lab, but in the field, airborne chemicals can be “blown away in seconds,” says Heil, who studies plant-insect interactions at the National Polytechnic Institute in Irapuato, Mexico.

Mithofer himself has no plans now to create genetically engineered sweet potato plants, because they would not be a viable (能活下去的) crop in Europe, where genetically modified crops are outlawed. So for now, Tainong 66 will have to put up with being a caterpillar salad bar.

57.What is the purpose of the experiment carried out by Axel's team?

A.To find out why DMNT has a very distinct smell.

B.To determine which sweet potato suits caterpillars better.

C.To find out why Tainong 57 resists bugs while Tainong 66 doesn't.

D.To determine what compounds are released when bugs eat sweet potatoes.

58.Which is an example of the underlined words “defense response” in Paragraph 4?

A.Researcher isolated the smelly chemical from plants.

B.Corn produces a chemical to avoid being eaten by bugs.

C.Two plants are put next to each other for an experiment.

D.Caterpillars have stomach trouble when they snack on sporamin.

59.The tone of the this passage can be described as .

A.humorous B.serious C.causal D.subjective 60.What's the author's attitude towards GM Tainong 66?

A.Supportive. B.Objective. C.Opposed. D.Skeptical.

Fred Rogers was a curious man, six feet tall and without pretense (虚伪). He liked to pray, to play the piano, to swim, and to write, and he somehow lived in a different world than I did. We became friends for some 20 years, and I made lifelong friends with his wife, Joanne. I remember thinking that it seemed as if Fred had access to another realm (领域) like the way pigeons have some special magnetic compass that helps them find home.

Fred died in 2003, somewhat quickly, of stomach cancer. He was 74. “Just don't make Fred into a saint (圣人),” That has become Joanne's refrain (叠句).91 now, still full of energy, she lives alone in the same roomy apartment, in the university section of Pittsburgh, that she and Fred moved into after they raised their two boys. Throughout her 50-year marriage to Fred, she wasn't the type to hang out on the set or attend production meetings. That was Fred's thing. He had his career, and she had hers as a concert pianist. For decades she toured the country with her college classmate, Jeannine Morrison, as a piano duo; they didn't retire the performance until 2008.

“If you make him out to be a saint, people might not know how hard he worked,”Joanne said. Disciplined, focused; a perfectionist — an artist. That was the Fred she and the cast and crew knew. “I think people think of Fred as a child-development expert,” David Newell, the actor who played Mr. “Speedy Delivery” McFeely, told me recently. “As a moral example maybe. But as an artist? I don't think they think of that.” that was the Fred I came to know. Creating, the creative impulse (冲动), and the creative process were our common interests. He wrote or co-wrote all the scripts for the program — all 33 years of it. He wrote the melodies. He wrote the lyrics. He structured a week of programming around a single theme, many of them difficult topics, like war, divorce, or death.

I don't know that he cared whether people saw him as an artist. He seemed more intent (急

切的) that people not see him at all. The focus was always on you. Or children. Or the tiny things. It was hard to see Fred.

I like you just the way you are. One day he told me where that core message came from. His grandfather, Fred Brooks McFeely, who like the rest of the Rogers family lived in Latrobe, Pennsylvania, about 40 miles east of Pittsburgh. “He was a character,” he said. “Oh, a lot of me came from him.”

His grandfather represented a life of risk and adventure, the very things Fred's boyhood lacked. He was a lonely kid, an only child until he was 11, when his sister came. He was bullied. Here comes Fat Freddie! He was sickly. He had asthma. He was not allowed to play outside by himself. He spent much of his childhood in his bedroom.

He had music, and he had puppets to keep himself amused. He didn't need much. He was expected to fill his father's shoes, become his business partner at the brick company. “My dad was pretty much Mr. Latrobe,” he told me. “He worked hard to accomplish all that he di d, and I've always felt that that was way beyond me. And yet I'm so grateful that he didn't push me to do the kinds of things that he did or to become a miniature (缩小的) version of him. It certainly would have been miniature.”

Fred wanted to be like his gra ndfather. “He taught me all kinds of really neat stuff!” he told me. “I remember one day my grandmother and my mother were telling me to get down, or not to climb, and my grandfather said: ‘Let the kid climb on the wall! He's got to learn to do things for himself!’ I heard that. I will never forget that. What a support that was. He had a lot of stone walls on his place.” “I think it was when I was leaving one time to go home after our time together,”Fred told me, “that my grandfather said to me: ‘You know, you made this day a really special day. Just by being yourself. There's only one person in the world like you. And I happen to like you just the way you are.”

61.What is the author's impression of Fred?

A.Fred had many lifelong friends.

B.Fred lived in a strange world.

C.Fred could always find way home.

D.Fred was an amazing person.

62.Why does Joanne try to persuade people not to make Fred into a saint?

A.To show the great success the couple achieved.

B.To underline the great pains Fred spared at work.

C.To remind people of the contributions she made.

D.To keep the weaknesses of Fred's character hidden.

63.Who may think Fred a moral example?

A.David Newell. B.The author. C.Common people. D.Joanne. 64.What did Fred prefer to do according to the author?

A.Write scripts and music on his own.

B.Act as the man behind the curtain.

C.Focus more on difficult topics.

D.Present himself as an artist.

65.Which of following might have the greatest influence on Fred's growth? A.His poor health condition. B.His father's expectation. C.His unhappy childhood. D.His grandfather's attitude. 66.What is mainly talked about in the passage?

A.The making of Fred Rogers.

B.The importance of a good wife.

C.The influence of a moral example.

D.The achievements of Fred and his wife.

七、任务型阅读

请认真阅读下列短文,并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。注意:每个空格只填1个单词。请将答案写在答题纸上相应题号的横线上。

Should I live in the city or the suburbs?

There are three different kinds of areas you can live in: urban, suburban, and rural. You can describe living in a rural area as living out in the sticks or the county This type of living is seen as idyllic (田园生活的) for those seeking reprieve (暂时缓解) from crowds. Rural areas generally have small, self -sustaining populations.

Urban living is city living: active nightlife, full of noise, sophisticated public transit system and sometimes small and expensive city apartments. Urban areas tend to be densely (密集地) populated and have more intense traffic and pollution as a result.

For those seeking an intermediary between urban and rural living, the suburbs might be just the thing. Suburbs are large residential areas away from the core of town yet close enough to the city center.

Can you afford to live in the city?

Choosing whether to live in the city or the suburbs is often a matter of budget — where can you afford to live? By and large, living in the city is more expensive than living in the suburbs, though that's not always the case. For instance, in Las Vegas, Phoenix, Pittsburgh, Cleveland, and a few other cities, suburban living is not always better on your wallet.

Your lifestyle influences your happiness in the city or suburbs.

For someone who enjoys five-star restaurants, vibrant (充满活力的) nightlife, and

fast-paced living, residing in an urban hub is a dream come true. On the other hand, if you find crowds and tons of noise unbearable, then a large city might feel like purgatory (炼狱).

Your lifestyle is one of the primary considerations in deciding where you ought to live. If you are into fishing, hiking, and spending time outdoors, then realize that you may have to drive several hours to enjoy your hobbies if you choose city living.

Is your career better suited for the city or suburbs?

Your career should also strongly influence your choice about whether to live in the city or in the suburbs. For example, if your job is in landscape, you might find it difficult to find work in the city because there is not a high demand for landscape artists. The fact of the matter is that most city homes don't have large yards with grass to cut, and competition for landscaping contracts is probably fierce. Similarly, a business executive (主管) may find that the suburbs do not offer the convenience afforded by city living.

The debate of whether to live in the suburbs or the city is long lasting and never-ending. When it all boils down to it, it is a matter of preference and budget, so go with your gut (决心) and you'll make the right choice.

江苏省南通市如皋市2020-2021学年度高三年级第一学期期末教学质量调研语文试题 语文试题 一、现代文阅读(35分) (一)现代文阅读I(本题共5小题,19分) 阅读下面的文字,完成1~5题。 材料一: 数字技术革命使技术与文化高度融合,同时影响了包含艺术生产与博物馆运营在内的所有非物质生产领域,改变了人类的思维与行为。新技术带给艺术博物馆领域中首要、直接的变化,主要表现在受众身上。 观众在“参与”作品的同时,其智识与艺术家的智识相互作用,可能形成新的、不可预见的智识结果,这成为艺术博物馆智识机制最基本的形式。观众可以通过博物馆平台反馈到艺术发展的历程中,乃至参与到整个社会的智识机制建构中。由此,博物馆可能不会直接解决21世纪困扰人类的许多问题,但是,通过让民众增进智识,它们可以在最终解决方案中发挥作用。 将社会学、哲学、历史学纳入到新时代的技术认知中来,参考一些包括人类学、社会学在内的研究方法(譬如仿效人类学通过多样化素材的叠加和分析),来重新观察艺术和生态秩序,是艺术博物馆面对信息时代所需要的智识精神。 回应受众的变化,策展强调与观众的融合与平等主要表现在策展内容、结构、过程、结果的开放。人与艺术在媒介的中介下形成一种“双重凝视”。展览呈现的作品需要观众的参与才完整,而策展人与艺术家在展览尚未成形时,创作出的作品从某种意义上是“未成形”作品。在展览展出的那一刻,作品被观众参与,被凝视,这样的状态又是一个流动的过程,作品因此才完整。 在新知识形态时代,我们认为艺术博物馆提供的不仅是艺术专业知识的直接

生产,而且是生产知识的动力——一种创新思维模式,一个智识生长的空间,我们把这样的博物馆运营指导思想,称为智识机制的建构。 交互将成为未来非常重要的艺术发展形式。在艺术博物馆,交互是一种艺术创作理念,也是博物馆的学术工作理念。博物馆与艺术家、观众形成社会化的沟通和教育,需要不断的交互,交互的概念更多考虑的是我们站在对方的角度来思考问题,而不是站在自己主观的角度去思考问题。 当然,博物馆的智识建构对未来教育也起到非常大的作用,这几年博物馆陆续在教育概念里提出学习概念,并探讨博物馆如何建造一种新的学习系统。在大学中,往往缺少创新的课程,博物馆在这个时期建立这样一个“智识”系统,可以让每个人都能够通过博物馆的“大脑系统”去思考,并生成新的知识,从而推动创造力! (摘编自张子康《用博物馆的“大脑”去思考》《光明日报》2020年12月27日)材料二: 自2008年IBM公司将信息技术、云计算技术和超级计算机当作主框架,建立起物与物之间的高度联系之后,“智慧地球”的概念就诞生了。2014年,IBM 公司和巴黎卢浮宫博物馆展开合作,构建起了全球第一所智慧博物馆。其主要依靠IBM公司提供的各种数据来优化博物馆相应的管理流程,以提高服务质量,实现实时运作管理形式。卢浮宫智慧博物馆建设开创先河后,世界各个国家也开始了解到智慧博物馆的重要性,尤其是在历史普及与文化建设方面。因此,智慧博物馆建设逐渐开始广泛起来。 智慧博物馆依靠物联网、移动互联网以及传感技术,在智能博物馆平台整合各类型的数据,并在此基础上更新优化博物馆管理服务模式。也正因为该方式,智能博物馆的文物设施感知能力越发增强,灵活能动性也越高,可以在管理运行时和游客开展互动交流,以满足不同类型游客的差异需求。 智慧博物馆这一概念的提出,在文博圈内引起了极大的反响,一些省市已经在逐步铺展智能博物馆建设计划。不过,由于移动互联网等数字信息技术自身的

江苏南通如皋市双马化工有限公司爆炸事故

江苏南通如皋市双马化工有限公司爆炸事故 2014年4月16日上午10时,如皋市双马化工有限公司造粒车间发生粉尘爆炸,接着引发大火,导致造粒车间整体倒塌。事故造成8人当场死亡,1人因抢救无效于5月11日死亡,8人受伤,其中2人重伤,直接经济损失约1594万元。 双马公司成立于1997年6月,位于江苏省南通市如皋市东陈镇南东陈村,现有员工246人,主要生产硬脂酸、甘油,生产能力硬脂酸10万吨/年,甘油1万吨/年。发生爆炸燃烧的造粒车间为单层钢构厂房,局部多层塔架,有4座直径4.5-7.0米、高约27米的造粒塔,架空于5米钢构平台上;造粒塔将熔融状

态下的硬脂酸由顶端喷入,通过与来自塔底部的气流逆流接触冷却,形成硬脂酸颗粒。 江苏省安全生产委员会副主任、江苏省安全生产监督管理局局长王向明说“江苏如皋(双马)化工厂爆炸给了我们非常惨痛的教训。我们在事后调查中发现,这起事故是完全可以避免的,是由非常低级的错误造成的。”王向明指出,今年4月16日如皋双马化工厂爆炸案是典型的由于“违章指挥、违规操作、违反劳动纪律”酿成的惨剧。他分析称:“首先,化工企业动火维修时,必须要停车检查,清空原料。然而该化工厂为了图方便,并没有停车,一边搞生产一边搞电缆,这是典型的违章指挥。其次,该企业没有取得动火作业(审批)表,就用电焊动火作业,属于违规操作。最后,该电焊工没有电焊资质,也没有经过系统培训,严重违反劳动纪律。然而该电焊工在作业时死亡,既是肇事者,也是受害者。” 王向明说,“爆燃当场造成8人死亡,还有一位抢救无效身亡,共造成了1500多万元的损失。然而这样的事故,是完全可以避免的。”王向明坦言,安全生产特别是危险化工行业的安全是“易碎品”。“只要稍有松懈,出事故是必然的,不出事故是偶然的。” 江苏省是全国危险化工作业大省,从2011年到2014年3月,江苏省化工领域未出现重大事故,但是今年4月、5月、6月连发三起有较大社会影响的事故:首起是4月16日如皋双马化工厂的爆燃事故,其次是5月29日宝应县曙光助剂厂发生爆炸事故,第三起是6月9日扬子石化炼油厂的爆燃事故。 对于连发的危险化工行业事故,王向明表示,江苏省安监局正在进行三方面综合整治:实行维修技改安全生产责任制;全面整治电焊工资质;推进高危行业从业人员培训。“我们将推行‘两个100%原则’:高危行业的企业负责人、安全生产管理人员和特种岗位作业人员100%持证上岗;所有新工人必须经过培训,100%
