ALife experiences can show one’s “grit”(坚韧). Complex challenges early in life helpedthe following people develop skills that got them to the top of their professions.Ursula Burns, Chairwoman, VEON; Former CEO, XeroxHer family was so poor that her single mother traded office cleaning for health care.But Burns’ early gift for maths won her a scholarship and an internship at Xerox, where she would compete her way to the top. “ I'm a black lady from the Lower East Side,” she says, “Not a lot scares me.”Howard Schultz, Executive Chairman, StarbucksSchultz grew up in public housing in Brooklyn, surrounded by poverty, and was the first in his family to go to college (on a football scholarship).After training in sales, he set up the company that would later buy Starbucks. “In the course of the year I spent trying to raise money, I spoke to 242 people, and 217 of them said no.” he said.Sean Combs, CEO, Sean JohnCombs began a generation of hip-hop talent and made a lasting influence on fashion.But he story could have turned out much differently: His drug dealer father was killed when he was3. “It made me work even harder.” he recently said.Geisha Williams, CEO, PG&EHer parents fled Cuba when Williams was 5. By 7, she was her parents main translator in talks with lawyers and accountants at grocery stores they owned.The experience did help her. “I went from thinking I could be a manager to thi nking I could do something much bigger.” she told Fortune.21.Who did best in math at school?bsB. BurnsC. SchultzD. Williams22.How did the death of Combs’ father influence him?A.It made him a failure.B.He became a drug dealer.C.It made him even stronger.D.He became a hip-hopper.23. What can we learn from the passage?A.Cuba is a good place to do business.B.No one wanted to help Schultz at first.C.Poor family kids can be successful easily.D.Difficulty in life pushed Williams forward.BLooking at a pile of old photos, I couldn't help feeling rather regretful.I've never got into the habit of sorting out photos. However, it's almost a habit of mine to have photos taken thoughtlessly. Thus, photos have been piling up in my childhood to womanhood. In spite of that, those black-and-white pictures taken in my early years are rarely kept, except a few survivals regarded as antiques.The bald(秃头的) baby picture of me that I treasured, the only one left, it's now missing.Familiar faces flash one by one before my eyes. Though the world is so small and we all live in it, yet we are separated by physical and psychological distances, some smaller, some larger.With the passage of time, one cannot, regretfully relive(重温) it with the same feeling as one had in the picture.What one can get from the old photos is but a bit of the past joy.One takes pictures with different persons in different time and places.They fill one with nostalgia(怀旧) in various degrees--some more, some less, and others none.That's why one has conflicting feelings towards the old photos. Still kept with the current ones, they're even less favored than a daily-used cup, which is always close to the owner.How these pieces of thought influence me. Photos keep our images rather than our sentiment, which may not remain.The image is always there but not its owner, whom the photo can't keep ,neither can it keep the event.Of course, there are some of the photos still holding my affection, such as those taken with my family members, with favorite playmates, fellow girl-students and best friends, not only inpictures but also in my life and heart.Now, since I have learned all this, I will not allow myself to be included casually in a photo taken with others. I'll make sure that the friendship can last before I take a photo with somebody.24.Why did the writer have only a few black-and-white pictures?A. She took fewer of them.B. She took photos thoughtlessly.C. She didn't take good care of them.D. She only liked the bald baby picture.25.What can we get from the old photos according to the writer?A. All the past events.B. Some past happiness.C. All the past excitement.D. The everlasting memory.26. What does the underlined word “sentiment” in paragraph 5 probably mean?A. LookB. ThoughtC. FeelingD. Influence27. What is the writer likely to do when asked to take photos others?A. To take the photo happily.B. To refuse the request politely.C. To ignore the request casually.D. To think carefully before action.CAs an Asian country, Singapore has a reputation for being highly westernized, with English among the country’s four official languages, but a couple of signs found on local buses that have recently become a hit online may say otherwise.Quite different from English we know, the sign read, for example, “Here cannot go in” instead of “No entry”, and Here can charge phone instead of Charge phone here. This language that resembles English is called Singaporean English or Singlish.The New York Times calls Si nglish “patchwork” because Singapore consists of migrants(移民) from several countries including China, India and Malaysia, and they all speak their own versions of “English”.“Everyone who speaks it shapes it,” wrote the newspaper.For example, in Singlish, you caneasily recognize influences from Chinese, including vocabulary such as” Mee Siam” and “da bao”. Sentence structures like ” toilet where” instead of “where’s the toilet” also come from Chinese.Interesting and diverse as it may seem, the trend for S inglish is worrying Singapore’s government. It is concerned that the dialect is lowering the country’s English standard and may affect its relationship with visitors.It even started the Speak Good English Movement.Unfortunately, the problem was not solved. Instead, Singlish has boomed, especially among young people who think of it as a sign of being cool and a way of identifying themselves as Singaporean.But this does not mean that standard English is being abandoned by young people. In fact, they are much more capable than the government gives credit--they can speak both.“We are a nation good at code switching-- we know that the way we speak to friends or drivers must be different from how act at work or school,” wrote Cheryl, a Singaporean author, in Ti me magazine, “To actively urge us to give up a language that speaks to the very heart of who we are, that's so beautifully represents the melting pot of Chinese, Indians, Malaysians and Eurasians that we are, is shortsighted, surely.”28. Why does Singapore have many different versions of English?A It is made up of migrants.B. It is highly westernized.C. It is influenced by Chinese.D. It is affected by official languages.29. What is the purpose of starting the Speak Good English Movement?A.To stop the new trend.B. To better the relationship.C. To keep the English standard.D. To give the government credit.30. What do the young people think of Singlish?A. It’s interesting.B. It’s their identity.C. It’s a sign of status.D. It’s a way of code-switching.31. What can we learn from what Cheryl said?A. Different people speak different styles of Singlish.B. Singlish is a more beautiful language than others.C. People speaks Singlish only to friends and drivers.D. People can use Singlish to express themselves well.DLong before iphones, the cigarette was the companion of choice for restlessness. And long before Facebook and WeChat, it was tobacco that promised to better your social life. Now, quitting smartphones has become the new quitting smoking.Of course, technology does not yellow your teeth, cause disease or lead to cancer. But some individuals are so concerned that device addiction is damaging their mental health. In order to reduce their dependence, even in Silicon Valley, people are turning off the messages that constantly buzz for their attention, banning smartphones from the bedroom and, curiously, changing the colors on their screens to a less tempting scale of gray.The big tech companies will have to work out how to respond to this new generation of quitters. Facebook is the first to go public with its attempt, hoping its recent move can make the social network more homely.Last year the tech industry got a bad name- Big Tech-with unfortunate echoes of other industries that have faced fierce opposition, including Big Tobacco. Like them, the tech industry has to reduce concern from a new generation of activist shareholders(股东) that are questioning its role in the world. These campaigns are never as fierce as those faced by Big Tobacco. In the 1990s, socially responsible investors refused to put money in tobacco stocks.It is far difficult for investors to challenge Big Tech and hard to separate the good these companies do in the world--connecting old friends and giving space for people to share their ideas--from the bad.In the meantime, stopping using technology remains problematic. In The World Without Mind: The Existential Threat of Big Tech, Franklin Foer argues that tech should be seen in a similar way to junk food: a convenience that some reject for more continuing nutrition.So we need to do more to turn the tide. In the same way that public service announcements made smoking around your children taboo(禁忌),we can warn parents against losing themselves in their smartphones while taking care of kids.We can also create no-smartphone zones at dinner. Eventually smartphones could be banned from all public places and help us give our attention tothe people around us instead.32. How did people keep close relationships with others in the past?A. By smoking.B. By drinking.C. By phoningD. By dining out.33. Why is the tech industry called Big Tech?A. It plays a bad role in the world.B. It is as big as Big Tobacco.C. It has an unfortunate name.D. It is a giant in Silicon Valley.34. What can we infer from Franklin Foer’s argument about the tech?A. It promotes social development.B. It is still favored by some people.C. It is worse than Big Tobacco.D. It offers continuing nutrition.35. Which can be the best title for the passage?A. Creating a No Smartphone LifeB. Smartphones Enrich Our Social LifeC. Smoking Does Greater Harm Than Smartphones DoD. Quitting Smartphones Is the New Quitting Smoking第二节(共5小题；每小题2分，满分10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。

2018年深圳市高三年级第二次调研考试语文答案及解析
2018年深圳市高三年级第二次调研考试语文参考答案及试题解析一、现代文阅读(35分)(一)论述类文本阅读(本题共3小题，9分)1.【参考答案】C【命题立意】本题考查考生理解语句、筛选并整合文中信息的能力。
能力层级为B级、C级。
【试题分析】A项前半句“新媒介产生负面效应的原因”源于原文第一段，后半句“人们在信息海洋中没有获得主动权、选择权”源于原文第三段。
从全文看，文章主要是从“媒体”和“信息受众”两大角度进行对策分析，因此，需要把对策转换为问题或原因，即“从媒体可以利用信息智能匹配技术降低受众的信息接收成本”可以转换为“受众的信息接收成本高”，从“从信息受众角度看，受众需要提高理性使用新媒介的能力”转换为“受众使用新媒体缺乏理性”。
由此可知A错。
B项源于原文第一段。
原文说“每天各种无用信息占据人们的大量时间，使人们非理性冲动增多，人际关系越来越淡薄，也更容易产生紧张和焦虑情绪”，三者是并列关系，而题目表述为因果关系，所以B项错误。
C项源于原文第二段，原文“一些媒体机构根据用户个人需求……进行精准信息推送”“虽然公司主要以推广自己服务项目为目的，但这种技术……接收自己需要的各种信息”，整合两层意思，可知C项正确。
D项，原文意思是媒体非常“注重用户的体验和选择”以达到“推广服务项目的目的”，所以D错。
）2.【参考答案】B【命题立意】本题考查考生分析论点、论据和论证方法的能力。
能力层级为C级。
【试题分析】本题是要求考生选出对原文论证的相关分析不正确的一项，答案是B。
A项是对原文论证前提和指向性分析。
立论前提由原文第一段“新媒介在……同时，产生的负面效应也不容忽视”可以推知；立论指向问题解决策略，即，“减少新媒介负面效应的对策”。
B项错。
B项是对文章核心论证问题的分析，前半句“文章围绕着为何要理性地使用新媒介这一问题”中“为何要理性地使用新媒介”概括错误，“为何”与“如何”区别很大，“为何”是原因分析，“如何”是怎样做，是从解决问题的角度去分析。

I’ll make sure that the friendship can last before I take a photo with somebody.24.Why did the writer have only a few black-and-white pictures?A.She took fewer of them.B.She took photos thoughtlessly.C.She didn’t take good care of them.D.She only liked the bald baby picture.25.What can we get from the old photos according to the writer?A.All the past events.B.Some past happiness.C.All the past excitement.D.The everlasting memory.26.What does the underlined word “sentiment” in paragraph 5 probably mean?A.Look.B.Thought.C.Feeling.D.Influence.27.What is the writer likely to do when asked to take a photo with others?A.To take the photo happily.B.To refuse the request politely.C.To ignore the request casually.D.To think carefully before action.CAs an Asian country, Singapore has a reputation for being highly westernized, with English among the country’s four official languages, but a couple of signs found on local buses that have recently become a hit online may say otherwise.Quite different from the English we know, the signs read, for example, “Here cannot go in” instead of “No Entry”, and “Here can charge phone” instead of “Charge phone here”.This language that resembles English is called Singaporean English, or “Singlish”.The New York Times calls Singlish “patchwork” because Singapore consists of migrants（移民）from several co untries including China, India and Malaysia, and they all speak their own versions of “English”.“Everyone who speaks it shapes it,” wrote the newspaper.For example, in Singlish you can easily recognize influences from Chinese, including vocabulary such as “Mee Siam” and “da bao”. Sentence structures like “toilet where” instead of “where’s the toilet” also come from Chinese.Interesting and diverse as it may seem, the trend for Singlish is worrying Singapore’s government. It is concerned that the dialec t is lowering the country’s English standard and may affect its relationship with visitors. It even started the Speak Good English Movement.Unfortunately, the problem was not solved. Instead, Singlish has boomed, especially among young people who think of it as a sign of being cool and a way of identifying themselves as Singaporean.But this doesn’t mean that Standard English is being abandoned by young people. In fact, they are much more capable than the government gives credit — they can speak both.“We are a nation good at code-switching — we know that the way we speak to friends or drivers must be different from how we act at work or school,” wrote Cheryl, a Singaporean author, in Time magazine. “To actively urge us to give up a language that speaks to the very heart of who we are, that so beautifully represents the melting pot of Chinese, Indians, Malaysians and Eurasians that we are, is shortsighted, surely.”28.Why does Singapore have many different versions of English?A.It is made up of migrants.B.It is highly westernized.C.It is influenced by Chinese.D.It is affected by official languages.29.What is the purpose of starting the Speak Good English Movement?A.To stop the new trend.B.To better the relationship.C.To keep the English standard.D.To give the government credit.30.What do the young people think of Singlish?A.It’s interesting.B.It’s their identity.C.It’s a sign of status.D.It’s a way of code-switching.31.What can we learn from what Cheryl said?A.Different people speak different styles of Singlish.B.Singlish is a more beautiful language than others.C.People speak Singlish only to friends and drivers.D.People can use Singlish to express themselves well.DLong before iPhones, the cigarette was the companion of choice for restlessness. And long before Facebook and WeChat, it was tobacco that promised to better your social life. Now, quitting smartphones has become the new quitting smoking.Of course, technology does not yellow your teeth, cause disease or lead to cancer. But some individuals are so concerned that device addiction is damaging their mental health. In order to reduce their dependence, even in Silicon Valley, people are turning off the messages that constantly buzz for their attention, banning smartphones from the bedroom and, curiously, changing the colours on their screens to a less tempting scale of grey.The big tech companies will have to work out how to respond to this new generation of quitters. Facebook is the first to go public with its attempt, hoping its recent move to make the social network feel more homely.Last year the tech industry got a bad name — Big Tech — with unfortunate echoes of other industries that have faced fierce opposition, including Big Tobacco. Like them, the tech industry has to reduce concern from a new generation of activist shareholders（股东）that are questioning its role in the world. These campaigns are never as fierce as those faced by Big Tobacco. In the 1990s, socially responsible investors refused to put money intobacco stocks.It is far difficult for investors to challenge Big Tech and hard to separate the good these companies do in the world — connecting old friends and giving space for people to share their ideas — from the bad. In the meantime, stopping using technology remains problematic. In The World Without Mind: The Existential Threat of Big Tech, Franklin Foer argues that tech should be seen in a similar way to junk food: a convenience that some reject for more continuing nutrition.So we need to do more to turn the tide. In the same way that public service announcements made smoking around your children taboo（禁忌）, we can warn parents against losing themselves in their smartphones while taking care of kids. We can also create no-smartphone zones at dinner. Eventually, smartphones could be banned from all public places and help us give our attention to the people around us instead.32.How did people keep close relationships with others in the past?A.By smoking.B.By drinking.C.By phoning.D.By dining out.33.Why is the tech industry called Big Tech?A.It plays a bad role in the world.B.It is as big as Big Tobacco.C.It has an unfortunate name.D.It is a giant in Silicon Valley.34.What can we inf er from Franklin Foer’s argument about tech?A.It promotes social development.B.It is still favored by some people.C.It is worse than Big Tobacco.D.It offers continuing nutrition.35.Which can be the best title for the passage?A.Creating a No Smartphone LifeB.Smartphones Enrich Our Social LifeC.Smoking Does Greater Harm Than Smartphones DoD.Quitting Smartphones Is the New Quitting Smoking第二节（共5 小题；每小题 2 分，满分10 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。

ALife experiences can show one’s“grit”（坚韧）Complex challenges early inlife helped the following people develop skills that got them to the top of their professions.Ursula Burns,Chairwoman,VEON;Former CEO,XeroxHer family was so poor that her single mother traded office cleaning for health care.But Bums’early gift for math won her a scholarship and an internship at Xerox,where she would compete her way to the top.“I’m a black lady from the Lower East Side”she says.“Not a lot scares me.”Howard Schultz,Executive Chairman,StarbucksSchultz grew up in public housing in Brooklyn,surrounded by poverty,and was the first in his family to go to college(on a football scholarship).After training in sales,he set up the company that would later buy Starbucks.“In the course of the year I spent trying to raise money,I spoke to242people,and217 of them said no.”he said.Sean Combs,CEO,Sean JohnCombs began a generation of hip-hop talent and made a lasting influence on fashion.But his story could have turned out much differently:his drng dealer father was killed when he was3.“It made me work even harder."he recently said.Geisha Williams,CEO,PG&EHer parents fled Cuba when Williams was5.By7,she was her parents’main translator in talks with lawyers and accountants at grocery stores they owned in New Jersey.The experience did help her.“I went from thinking I could be a manager to thinking I could do something much bigger.”she told Fortune.21.Who did best in math at school?bs.B.Bums.C.Schultz.D.Williams.22.How did the death of Combs’father influence him?A.It made him a failure.B.He became a drug dealer.C.It made him even stronger.D.He became a hip-hopper.23.What can we learn from the passage?A.Cuba is a good place to do business.B.No one wanted to help Schultz at first.C.Poor family kids can be successful easily.D.Difficulty in life pushed Williams forward.BLooking at a pile of old photos,I couldn’t help feeling rather regretful.I’ve never got into the habit of sorting out photos.However,it’s almost a habit of mine to have photos taken thoughtlessly.Thus,photos have been pilingup in my childhood to womanhood.In spite of that,those black-and-white pictures taken in my early years are rarely kept,except a few survivals regarded as antiques.A bald（秃头的）baby picture of me that I treasured,the only one left,is now missing.Familiar faces flash one by one before my eyes.Though the world is so small and we all live in it,yet we are separated by physical and psychological distances,some smaller,some larger.With the passage of time,one cannot, regretfully,relive（重温）it with the same feeling as one had in the picture.What one can get from the old photos is but a bit of the past joy.One takes pictures with different persons in different time and places. They fill one with nostalgia（怀旧）in various degrees--some more,some less, and others none.That’s why one has conflicting feelings towards the old photos. Still kept with the current ones,they are even less favored than a daily-used cup, which is always close to the owner.How these pieces of thought influence me!Photos keep our images rather than our sentiment,which may not ren1ain.The image is always there,but not its owner,whom the photo cannot keep,neither can it keep the event.Of course,there are some of the photos still holding my

新媒介是一把双刃剑，在方便人们的日常生活、拓展人的行为能力以及提供各种超感官体验时，其产生的负面效应也不容忽视。
每天各种无用信息占据人们的大量时间，使人们非理性冲动增多，人际关系变得越来越淡薄，也更容易产生紧张和焦虑情绪。
要解决这一问题，就必须从媒体与受众两方面入手，积极寻求对策。
从媒体角度看，媒体可以利用信息智能匹配技术降低受众的信息接收成本。
这项技术以数据分析为依托，使信息更加智能化、个性化，从而与受众的需求相匹配。
比如，一些媒体机构根据用户个人需求方面的关键词、以往浏览的相关数据以及学历、职业、爱好等特征信息，进行汇集、整理、跟踪和分析，并根据用户充值、消费、反馈等数据信息，了解和掌握不同用户的个性化潜在需求，进行精准的信息推送。
虽然公司主要以推广自己服务项目为目的，但这种技术更注重用户的体验和选择，会大大减少许多有意无意强加于受众的信息，从而降低了受众进行信息处理的时间成本，使其在轻松愉悦的状态中接收自己需要的各种信息。
这样的智能匹配模式会越来越精细化、个性化和特色化。
比如，有的技术可以根据手机定位，确定用户是在办公场所、家里还是旅途中来推送合适的视听内容；还可以根据用户手机的睡眠模式、工作模式等确定推送时间，以及根据某一信息关注度的高低确定是否推送。
从信息受众角度看，受众需要提高理性使用新媒介的能力。
受众首先要提升自己的媒介素养，即对媒介本身带来的危害及个人在媒介使用过程中存在的问题保持清醒认识的能力。

The experience did help her. “I went from thinking I could be a manager to thinking I could do something much bigger.” she told Fortune.21.Who did best in math at school?bs.B.Burns.C.Schultz.D.Williams.22.How did the death of Combs’ father influence him?A.It made him a failure.B.He became a drug dealer.C.It made him even stronger.D.He became a hip-hopper.23.What can we learn from the passage?A.Cuba is a good place to do business.B.No one wanted to help Schultz at first.C.Poor family kids can be successful easily.D.Difficulty in life pushed Williams forward.BLooking at a pile of old photos, I couldn’t help fe eling rather regretful.I’ve never got into the habit of sorting out photos. However, it’s almost a habit of mine to have photos taken thoughtlessly. Thus, photos have been piling up in my childhood to womanhood. In spite of that, those black-and-white pictures taken in my early years are rarely kept, except a few survivals regarded as antiques. A bald（秃头的）baby picture of me that I treasured, the only one left, is now missing.Familiar faces flash one by one before my eyes. Though the world is so small and we all live in it, yet we are separated by physical and psychological distances, some smaller, some larger. With the passage of time, one cannot, regretfully, relive（重温）it with the same feeling as one had in the picture. What one can get from the old photos is but a bit of the past joy.One takes pictures with different persons in different time and places. They fill one with nostalgia（怀旧）in various degrees —some more, some less, and others none. That’s why one has conflicting feelings towards the old photos. Still kept with the current ones, they are even less favored than a daily-used cup, which is always close to the owner.How these pieces of thought influence me! Photos keep our images rather than our sentiment, which may not remain. The image is always there, but not its owner, whom the photo cannot keep, neither can it keep the event.Of course, there are some of the photos still holding my affection, such as those taken with my family members, with favorite playmates, fellow girl-students and best friends, not only in pictures but also in my life and heart.Now, since I have learned all this, I will not allow myself to be included casually in a photo taken with others. I’ll make sure that the friendship can last before I take a photo with somebody.24.Why did the writer have only a few black-and-white pictures?A.She took fewer of them.B.She took photos thoughtlessly.C.She didn’t take good care of them.D.She only liked the bald baby picture.25.What can we get from the old photos according to the writer?A.All the past events.B.Some past happiness.C.All the past excitement.D.The everlasting memory.26.What does the underlined word “sentiment” in paragraph 5 probably mean?A.Look.B.Thought.C.Feeling.D.Influence.27.What is the writer likely to do when asked to take a photo with others?A.To take the photo happily.B.To refuse the request politely.C.To ignore the request casually.D.To think carefully before action.CAs an Asian country, Singapore has a reputation for being highly westernized, with English among the country’s four official languages, but a couple of signs found on local buses thathave recently become a hit online may say otherwise.Quite different from the English we kno w, the signs read, for example, “Here cannot go in” instead of “No Entry”, and “Here can charge phone” instead of “Charge phone here”.This language that resembles English is called Singaporean English, or “Singlish”.The New York Times calls Singlish “patchwork” because Singapore consists of migrants（移民）from several countries including China, India and Malaysia, and they all speak their own versions of “English”.“Everyone who speaks it shapes it,” wrote the newspaper.For example, in Singlish you can easily recognize influences from Chinese, including vocabulary such as “Mee Siam” and “da bao”. Sentence structures like “toilet where” instead of “where’s the toilet” also come from Chinese.Interesting and diverse as it may seem, the trend for Singlish is worrying Singapore’s government. It is concerned that the dialect is lowering the country’s English standard and may affect its relationship with visitors. It even started the Speak Good English Movement.Unfortunately, the problem was not solved. Instead, Singlish has boomed, especially among young people who think of it as a sign of being cool and a way of identifying themselves as Singaporean.But this doesn’t mean that Standard English is being abandoned by young people. In fact, they are much more capable than the government gives credit — they can speak both.“We are a nation good at code-switching — we know that the way we speak to friends or drivers must be different from how we act at work or school,” wrote Cheryl, a Singaporean author, in Tim e magazine. “To actively urge us to give up a language that speaks to the very heart of who we are, that so beautifully represents the melting pot of Chinese, Indians, Malaysians and Eurasians that we are, is shortsighted, surely.”28.Why does Singapore have many different versions of English?A.It is made up of migrants.B.It is highly westernized.C.It is influenced by Chinese.D.It is affected by official languages.29.What is the purpose of starting the Speak Good English Movement?A.To stop the new trend.B.To better the relationship.C.To keep the English standard.D.To give the government credit.30.What do the young people think of Singlish?A.It’s interesting.B.It’s their identity.C.It’s a sign of status.D.It’s a way of code-switching.31.What can we learn from what Cheryl said?A.Different people speak different styles of Singlish.B.Singlish is a more beautiful language than others.C.People speak Singlish only to friends and drivers.D.People can use Singlish to express themselves well.DLong before iPhones, the cigarette was the companion of choice for restlessness. And long before Facebook and WeChat, it was tobacco that promised to better your social life. Now, quitting smartphones has become the new quitting smoking.Of course, technology does not yellow your teeth, cause disease or lead to cancer. Butsome individuals are so concerned that device addiction is damaging their mental health. In order to reduce their dependence, even in Silicon Valley, people are turning off the messages that constantly buzz for their attention, banning smartphones from the bedroom and, curiously, changing the colours on their screens to a less tempting scale of grey.The big tech companies will have to work out how to respond to this new generation of quitters. Facebook is the first to go public with its attempt, hoping its recent move to make the social network feel more homely.Last year the tech industry got a bad name — Big Tech — with unfortunate echoes of other industries that have faced fierce opposition, including Big Tobacco. Like them, the tech industry has to reduce concern from a new generation of activist shareholders（股东）that are questioning its role in the world. These campaigns are never as fierce as those faced by Big Tobacco. In the 1990s, socially responsible investors refused to put money in tobacco stocks.It is far difficult for investors to challenge Big Tech and hard to separate the good these companies do in the world — connecting old friends and giving space for people to share their ideas — from the bad. In the meantime, stopping using technology remains problematic. In The World Without Mind: The Existential Threat of Big Tech, Franklin Foer argues that tech should be seen in a similar way to junk food: a convenience that some reject for more continuing nutrition.So we need to do more to turn the tide. In the same way that public service announcements made smoking around your children taboo（禁忌）, we can warn parents against losing themselves in their smartphones while taking care of kids. We can also create no-smartphone zones at dinner. Eventually, smartphones could be banned from all public places and help us give our attention to the people around us instead.32.How did people keep close relationships with others in the past?A.By smoking.B.By drinking.C.By phoning.D.By dining out.33.Why is the tech industry called Big Tech?A.It plays a bad role in the world.B.It is as big as Big Tobacco.C.It has an unfortunate name.D.It is a giant in Silicon Valley.34.What can we infer from Franklin Foer’s argument about tech?A.It promotes social development.B.It is still favored by some people.C.It is worse than Big Tobacco.D.It offers continuing nutrition.35.Which can be the best title for the passage?A.Creating a No Smartphone LifeB.Smartphones Enrich Our Social LifeC.Smoking Does Greater Harm Than Smartphones DoD.Quitting Smartphones Is the New Quitting Smoking第二节（共5 小题；每小题2 分，满分10 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。
