文章大意:这是一篇说明文。文章主要说明了父母经常担心社交媒体对孩子性格的影响,也许比花在网上的时间更令人担忧的是研究结果表明,社交媒体的使用实际上会影响用户的个性和性格。
1 . 阅读下面短文,根据题目要求用英文回答问题。

Is social media messing with children’s morals?

Parents are often concerned about the effects of social media on their children’s character. We have all heard complaints that young people are spending too much time online and not enough time in the “real world” —with studies showing that nearly three-quarters of 12 to 15-year-olds in the UK have a social media profile and spend an average of 19 hours a week online.

More worrying, perhaps, than the amount of time spent online, are the findings that suggest social media use can actually influence users’ personality and character. Recent research, for example, shown that there is a link between social media use and narcissism (自恋), and that the use of social networking websites may have an nagative effect on social decision making and reduce levels of empathy (同情心).

With this in mind, one of the latest research projects at the Jubilee Centre for Character and Virtues, looks at the impact social media has on young people’s character and moral development, and aims to understand the benefits social media can have on development.

The first stage of the research involved a “parent poll (survey)” of 1,738 parents of 11 to 17-year-olds from across the UK asked a series of questions on their feelings around social media, and the moral (or immoral) messages that appear online. Our findings so far indicate that parents’ attitudes towards social media are largely negative–over a half of parents we questioned agree that social media “hinders or weakens” a young person’s character or moral development. While only 15% of respondents agreed that social media could “enhance or support” it.

However, it isn’t all doom and gloom, because our research also shows that social media can be a source for good. Nearly three quarters of the parents who use social media on a regular basis reported seeing content with a positive moral message at least once a day-including humour, appreciation of beauty, creativity, kindness, love and courage. And it could well be, that viewing this type of positive online content could have a positive influence on young people’s attitudes and behaviours.

This is because on social media sites, users often come across new perspectives and situations-such as different religions, cultures and social groups. And exposure to these situations online could actually help young people be more understanding and tolerant—and in turn develop their empathy skills. This is because it allows them to view things from other people’s perspectives, in a way they might not be able to in “real life”.

Of course, this translation from exposure to empathy may not always follow-which can be seen in the high rates of cyber bullying. According to a 2015 report, 62% of 13 to 20-year-olds who had been bullied reported some degree of cyber bullying—which shows that empathy doesn’t always play a part in online environments.

But while it may be tempting for some parents to just ban social media use altogether, it is unlikely to be a successful strategy in the long term-social media is not going away. Instead, we need to better understand the relationship between social media use and a young person’s character and moral values. And through our research, we hope to be able to offer constructive evidence-based advice on exactly this.

Because it is clear that the online environment is a moral terrain which requires successful navigation. By understanding how some immoral events can be avoided, we can help to create a safer and more even path for young people to negotiate.

1. According to the research, what are the parents’ attitudes towards social media?
___________________________________________________________
2. Why could viewing positive online content have a positive influence on young people’s attitudes and behaviours?
___________________________________________________________
3. Please decide which part is false in the following statement, then underline it and explain why.
For parents, it is a good strategy to ban social media because it may have a negative influence on young people’s moral development.
___________________________________________________________
4. Please briefly present your opinion on how to be a moral person on social media. (In about 40words)

文章大意:本文是新闻报道。文章主要介绍了全球人口增长带来的粮食问题,以及如何通过精准农业等可持续农业实践来解决这个问题。

2 . The issue of how to feed a growing population is a crucial issue for the 21st century. The issue was high on the agenda (当务之急) at the recent United Nations Climate Change Conference in Egypt. According to the UN, by 2050, we will need to produce 60% more food to feed a world population of 9.3 billion.

Cambridge Judge Business School supports a number of businesses which aim to promote sustainable agriculture practices. One of the most important fields is precision (精准) agriculture, the science of improving crop yields and assisting management decisions using the latest technology. Outfield Technologies is targeted at high value fruit farming. Farmers buy their own drones (无人机), and then the Outfield software creates flight plans over the farm and processes the images taken by the drones.

By counting the fruit on branches and measuring trees, farmers can see where to apply fertiliser with greater precision, reducing usage and improving soil sustainability. Outfield’s software can also recommend where to start harvesting to reduce waste and labour costs. The rising cost of labour globally has become a huge issue within the agricultural industry, for reasons including the shortage of backpackers (some of whom become seasonal workers) in New Zealand, and the rise of minimum pay in South Africa.

The data gathered by drones can also predict yields. “Priming” the supply chain ensures a smoother journey from the farm to fruit bowl in your home. When an apple is picked, it is stored in a refrigerated environment for up to six months before being transported to a pack house to be washed, sorted, packaged, before being moved to a delivery centre and finally appearing on supermarket shelves. The chain depends heavily on transportation, but by predicting yields, Outfield aims to reduce waste as traders can predict fruit levels and reduce greenhouse gases caused by refrigerated storage.

Outfield co-founder Oil Hilbourne said, “The agricultural industry needs more investment to change. More money for 5G, education and investment in start-ups.”

1. What does Outfield Technologies do for farmers?
A.It offers them free flights.
B.It oversees farms for them.
C.It teaches them about high value fruits.
D.It uses drone-taken images to advertise farms.
2. What labour problems are different countries facing?
A.Pay in South Africa is very low.
B.South Africa can’t agree on minimum pay.
C.Backpackers in New Zealand fail to get paid fairly.
D.New Zealand isn’t drawing enough seasonal workers.
3. By gathering data by drone, the Outfield tries to_________.
A.boost the yield of fruitB.make sure the fruit can keep fresh
C.ensure the fruits are transported timelyD.provide more convenient services to customers
4. Which would be the best title for the passage?
A.The future of farmingB.The trend of fruit picking
C.The promising market of high value fruitsD.The positive effects of farming on environment

文章大意:本文是一篇记叙文。本文主要讲述了Anna Sacks的个人生活故事。她曾在纽约一家银行工作,虽然生活幸福但感觉缺乏重要性。她参加了农业项目Adamah,学习可持续生活和种植可持续食物,这改变了她的生活目标和技能,同时她开始关注消费文化带来的损害,并通过拣选垃圾来展示这个问题。她希望引起人们对于过度购买和浪费的关注,从而引发改变。

3 . Working at a bank in New York City in the mid-2010s, Anna Sacks was living the life-just not the life she wanted. Sure, she was happy. But she wanted to do something that felt important.

Some people seeking meaning might read a self-help book or perhaps volunteer a few hours a week. Sacks packed up her life and moved to Connecticut to participate in Adamah, a farming program that focuses on sustainable living and growing sustainable food. When she returned to New York, her life was with a new purpose and a variety of new skills to make her dreams a reality.

“One of the things that really stuck with me from Adamah was how little waste they produced and how they handled the waste they did have, primarily through composting (堆肥),” she says. “And I just thought, ‘Why aren’t we doing that here?’”“The Adamah program opened Sacks’ eyes to the damage consumer culture is doing on a local, national, and global level, and the need to find solutions. So in 2017, she began what she calls “trash walking”.

During tours around her community, Sacks picks through garbage to look for reusable items. Soon, her “trash walking” expanded to include corporate trash along with residential trash. Surprisingly, she discovered a wide range of really great stuff-like clothing, decorations, and food-all of which she documents on TikTok.

Under the name The Trash Walker, Sacks quickly gained popularity for her videos that highlight the problems with consumerism. “The root issue is overproduction, which leads to overconsumption, which leads to a large amount of waste,” she says.

The fact is, companies often choose to trash items rather than give them away to people who might need them. A big reason for this waste is the way our current tax laws are structured, Sacks says. Sellers who destroy goods can claim the cost as a loss on their taxes and be refunded. If they give away goods, they can claim only a small amount as a charitable reduction on their taxes.

Sacks’ main focus is simply getting people to pay attention to how many unnecessary things they buy and then throw away. “Once you become aware of the way you consume, you can see ways you improve,” she says.

1. Anna Sacks packed up her life and left New York to________.
A.lead a healthy lifestyle
B.observe how to grow food
C.pursue a meaningful life
D.volunteer to work in a bank
2. What impressed Anna Sacks most about the Adamah program?
A.The importance of trash walking.
B.The sustainable food people produced.
C.The hard truth about consumer culture.
D.The way people there dealt with the waste.
3. What makes companies prefer to throw out goods as trash?
A.The tax reduction.
B.The quality of goods.
C.The tax refund.
D.The overproduction.
4. What can we learn from Anna Sacks’ story?
A.Consumer culture accounts for wasting.
B.Corporate trash outweighs residential trash.
C.Trash walking is the key to becoming wealthy.
D.Turning to farming leads to sustainable living.

文章大意:这是一篇说明文。文章主要说明了人类生来喜爱比较,但互联网让人们比较的范围变得更大,对人们的生活也产生了一定影响。

4 . We humans are comparison creatures.     1     This quality may have evolved as a means of helping us fit into the social hierarchy (等级) of the cultures we inhabited. Regardless of the reasons, social comparison plays a significant role in how we view and evaluate ourselves, and how we interact with our world.

It used to be that our primary reference of comparison was our local communities, primarily neighbors and co-workers. Because we tend to gather around those similar to ourselves in terms of educational level, work income, and shared interests, the range of differences when we compared ourselves to others was fairly small. Unfortunately, with the emergence of the Internet, we can now compare ourselves to literally anyone in the world.     2     What had in previous generations been a small gap in our comparisons has now become so large and unattainable.

    3     When so many people that are easily discoverable on the Internet seem to be so successful. famous, influential and beautiful, given our preference to compare, it is difficult not to have it influence how we view ourselves. Sadly, these comparisons usually result in our feeling inadequate and “less than”.

These harmful comparisons also damage our emotional lives. When we feel lacking, we experience a variety of unpleasant and unhealthy emotions. We feel jealousy and envy for what others have and what we lack.     4    

It’s one thing to realize that you compare yourself to others. It’s another thing to recognize that social comparison is often corrosive (逐步侵蚀的) to you in so many ways psychologically and emotionally. It’s an entirely other thing to stop yourself from comparing yourself to others.     5    

A.We are constantly measuring ourselves against other people.
B.Yet it is possible, and it is worth the effort for your mental health.
C.Thus, we are now exposed to groups that are quite different from us.
D.We believe that there is something wrong with us compared to others.
E.We can even feel bitterness and anger at others for the unfairness of it all.
F.Comparing ourselves to others has the potential to increase our life experience.
G.This new level of comparison has huge implications for our psychological lives.

文章大意:本文是说明文。主要介绍了网络或者报纸上有时会出现某些虚假消息并对其发生原因进行了分析,同时指出对此网站或者报纸编辑室应该高度重视。

5 . In June 2022, Huffington Post and Mail Online reported that three-year-old Victoria Wilcher, who had suffered facial scarring (结疤), had been kicked out of a KFC because she was frightening customers. Later, KFC announced that no evidence had been found to support the story. This phenomenon is largely a product of the increasing pressure in newsrooms that care more about traffic figures.

Brooke Binkowski, an editor, says that, during her career, she has seen a shift towards less editorial oversight in newsrooms. “Clickbait is king, so newsrooms will uncritically print something unreal. Not all newsrooms are like this, but a lot of them are.”

Asked what the driving factor was, a journalist said, “There is undoubtedly pressure to churn out (粗制滥造) stories in order to get clicks, because they equal money. At my former employer in particular, the pressure was on due to the limited resources. That made the environment quite horrible to work in.”

In a February 2023 report for Digital Journalism, Craig Silverman wrote, “Today the bar for what is worth giving attention to seems to be much lower. Within minutes or hours, a badly sourced report can be changed into a story that is repeated by dozens of news websites, resulting in tens of thousands of shares. Once a certain critical mass is reached, repetition has a powerful effect on belief. Thus, the rumor simply becomes true for readers.”

And, in spite of the direction that some newsrooms seem to be heading in, a critical eye is becoming more, not less important, according to the New York Times’ public editor, Margaret Sullivan. “Reporters and editors have to be more careful than ever before. It’s extremely important to question and to use every verification (验证) method available before publication.” Yet those working in newsrooms talk of doubtful stories being tolerated because, in the words of some senior editors, “a click is a click, regardless of the advantage of a story”. And, “if the story does turn out to be false, it’s simply a chance for another bite at the cherry.”

Verification and fact-checking are regularly falling victim to the pressure to bring in the numbers, and if the only result of being caught out is another chance to bring in the clicks, that looks unlikely to change.

1. According to Brooke Binkowski, newsrooms produce false news because         .
A.clicks matter a lotB.resources are limited
C.money is needed for newsD.journalists lack experience
2. What does Craig Silverman’s remark probably mean?
A.Lies can’t sell without an atom of truth.
B.Rumors are like a flame blown by the wind.
C.You can hear rumors, but you can’t know them.
D.A lie, repeated frequently enough, will end up as truth.
3. What is the author’s attitude towards the newsrooms?
A.Pessimistic.B.Supportive.C.Subjective.D.Sympathetic.
4. What is the passage mainly about?
A.Consequences of false stories.B.Causes of online false news.
C.Inability of journalists.D.A craze to get clicks.

文章大意:本文是一篇议论文。文章探讨了好奇心和不满足感对于成功的重要性,认为这两种深层次的人类驱策力比野心更重要。文章建议我们激发好奇心和不满足感,并勇于接触新事物和挑战传统,不断提高自己。最后,文章强调现在是开始行动的最佳时机。

6 . After years of observing human nature, I have decided that two qualities make a difference between men of great achievement and men of average performance — curiosity and discontent. I have never known an outstanding man who lacked either. And I have never known an average man who had both.

Together, these deep human urges (驱策力) count for much more than ambition. Galileo was not merely ambitious when he dropped objects of varying weights from the Leaning Tower at Pisa and timed their fall to the ground. Like Galileo, all the great names in history were curious and asked in discontent, “Why? Why? Why?”

Fortunately, curiosity and discontent don’t have to be learned. We are born with them and need only to recapture them. “The great man,” said Mencius, “is he who does not lose his child’s heart.” Yet most of us do lose it. We stop asking questions. We stop challenging custom. We just follow the crowd. And the crowd desires only the calm and restful average.

Most of us meet new people, and new ideas, with hesitation. But once having met and liked them, we think how terrible it would have been, had we missed the chance. We will probably have to force ourselves to waken our curiosity and discontent and keep them awake.

How should you start? Modestly, so as not to become discouraged. I think of one friend who couldn’t arrange flowers to satisfy herself. She was curious about how the experts did it.

The way to begin is to answer your own excuses. You haven’t any special ability? Most people don’t; there are only a few geniuses. You haven’t any time? That’s good, because it’s always the people with no time who get things done. Harriet Stowe, mother of six, wrote parts of Uncle Tom’s Cabin while cooking. You’re too old? Remember that Thomas Costain was 57 when he published his first novel, and that Grandma Moses showed her first pictures when she was 78.

However you start, remember there is no better time to start than right now, for you’ll never be more alive than you are at this moment.

1. In writing Paragraph 1, the author aims to ________.
A.present an argumentB.make a comparisonC.reach a conclusionD.propose a definition
2. What does the example of Galileo tell us?
A.Scientists tend to have varied ambitions.B.Trial and error leads to the finding of truth.
C.Creativity results from challenging authority.D.Greatness comes from a lasting desire to explore.
3. What can you do to recapture curiosity and discontent?
A.Observe the unknown around you.B.Develop a questioning mind.
C.Lead a life of adventure.D.Follow the fashion.
4. What can we learn from the last two paragraphs?
A.Gaining success helps you become an expert.
B.The genius tends to get things done creatively.
C.Lack of talent and time is no reason for taking no action.
D.You should remain modest when approaching perfection.

文章大意:这是一篇议论文。文章讨论了工作中的责备问题,说明工作中不能一味地指责别人。

7 . Casting blame is natural: it is tempting to fault someone else for a mistake rather than taking responsibility yourself. But blame is also harmful. It makes it less likely that people will own up to mistakes, and thus less likely that organizations can learn from them. Research published in 2015 suggests that firms whose managers pointed to external factors to explain their failings underperformed companies that blamed themselves.

Blame culture can spread like a virus. Just as children fear mom and dad’s punishment if they admit to wrongdoing, in a blaming environment, employees are afraid of criticism and punishment if they acknowledge making a mistake at work. Blame culture asks, “who dropped the ball?” instead of “where did our systems and processes fail?” The focus is on the individuals, not the processes. It’s much easier to point fingers at a person or department instead of doing the harder, but the more beneficial, exercise of fixing the root cause, in which case the problem does not happen again.

The No Blame Culture was introduced to make sure errors and deficiencies (缺陷) were highlighted by employees as early as possible. It originated in organizations where tiny errors can have catastrophic (灾难性的) consequences. These are known as high reliability organizations (HROs) and include hospitals, submarines and airlines. Because errors can be so disastrous in these organizations, it’s dangerous to operate in an environment where employees don’t feel able to report errors that have been made or raise concerns about that deficiencies may turn into future errors. The No Blame Culture maximizes accountability because all contributions to the event occurring are identified and reviewed for possible change and improvement.

The National Transportation Safety Board (NTSB), which supervises air traffic across the United States, makes it clear that its role is not to assign blame or liability but to find out what went wrong and to issue recommendations to avoid a repeat. The proud record of the airline industry in reducing accidents partly reflects no-blame processes for investigating crashes and close calls. The motive to learn from errors also exist when the risks are lower. That is why software engineers and developers routinely investigate what went wrong if a website crashes or a server goes down.

There is an obvious worry about embracing blamelessness. What if the website keeps crashing and the same person is at fault? Sometimes, after all, blame is deserved. The idea of the “just culture”, a framework developed in the 1990s by James Reason, a psychologist, addresses the concern that the incompetent and the malevolent (恶意的) will be let off the hook. The line that Britain’s aviation regulator draws between honest errors and the other sort is a good starting-point. It promises a culture in which people “are not punished for actions or decisions taken by them that match with their experience and training”. That narrows room for blame but does not remove it entirely.

1. According to the research published in 2015, companies that ______ had better performance.
A.blamed external factorsB.admitted their mistakes
C.conducted investigationsD.punished the under performers
2. According to the passage, what do you learn about the No Blame Culture?
A.It encourages the early disclosure of errors.
B.It only exists in high reliability organizations.
C.It enables people to shift the blame onto others.
D.It prevents organizations from making any error.
3. What is the major concern about embracing blamelessness according to the passage?
A.Innocent people might take the blame by admitting their failure.
B.Being blamed for mistakes can destroy trust in employees.
C.The line between honest errors and the other sort is not clear.
D.People won’t learn their lessons if they aren’t blamed for failures.
4. Which of the following is the best title for the passage?
A.Why We Fail to Learn from Our Own Mistakes
B.How to Avoid Disastrous Errors in Organizations
C.Why We Should Stop the Blame Game at Work
D.How to Deal with Workplace Blame Culture

9 . 阅读下面短文,根据题目要求回答问题。

You are watching your favorite TV show when a commercial break starts. First you see an ad for candy. Then there is one for fast food. Your stomach growls. Suddenly, all you can think about is how much you need a snack.

If that sounds familiar, you are not alone. Researchers from McMaster University in Canada studied the effects of junk food ad. The researchers examined the effects of advertising junk food on more than 6000kids through TV commercials and other types of media. They found that kids made unhealthy food and drink choicesas quickly as 30 minutes after seeing the ads.

“There is too much unhealthy food advertising out there,” Says Behnam Sadeghirad. He’s one of the researchers who led the study. “This is dangerous for younger children.”

Food and drink ads are everywhere from TV to the Internet. Companies want to make sure you know about their products. They spend nearly 1.8 billion a year on food ads aimed at kids according to a report.

The Nielsen Company tracked the number of food ads that kids saw in 2015. It found that kids watched nearly 12 food ads on TV each day. Most of these ads weren’t for health y foods. In fact, on average. kids saw only one ad per week for fruits and vegetables. Instead, most of the ads were for fast food, candy and sugary drinks.

Jennifer Harris, a professor at the University of Connecticut, says this is a big part of the problem. “Unhealthy foods are not things we should be encouraging kids to eat more often”. Harris says. “But unfortunately those are the products being advertised to them the most”.

Health experts say it’s OK to treat yourself to a cookie once in a while. But what can you do to keep from having an unhealthy snack every time you see an ad for junk food? Harris says it’s important to learn to spot the techniques companies use in their ads, tell their kids what is going on and help kids think about whether these products are good for them.

1. What did researchers from MaMaster University find?
____________________________________________________________________
2. What do the findings of the Nielsen Company suggest?
____________________________________________________________________
3. Please decide which part is false in the following statement, then underline it and explain why.
To avoid negative impacts of advertisements for unhealthy food, parents should keep their kids from watching these kinds of advertisements.
____________________________________________________________________
4. Please briefly describe what you can do to reduce the negative impact of advertising on your life.

文章大意:本文是一篇议论文。文章认为社交媒体会给用户带来各种影响,有积极的,也有消极的,人们应该理性使用社交媒体。

10 . By now, we are all aware that social media has had a tremendous influence on our culture, in business, on the world-at-large. Social media websites revolutionized the way people communicate and socialize on the Web. However, aside from seeing your friend’s new baby on Facebook, or reading about Justin Bieber’s latest conflict with the law on Twitter, what are some of the real influences?

Social networks offer the opportunity for people to re-connect with their old friends and acquaintances, make new friends, share ideas and pictures, and many other activities. Users can keep pace with the latest global and local developments, and participate in campaigns and activities of their choices. Professionals use social media sites like LinkedIn to enhance their career and business development. Students can work together with their peers to improve their academic and communication skills.

Unfortunately, there are a few downsides too to social networking. If you are not careful, immoral people can target you for cyber bullying and disturbance on social sites. School children, young girls, and women can fall victim to online attacks which can create tension and suffering. If you are a victim of cyber bullying, do not take it lying down, but try to take appropriate legal action against the attacker.

Many companies have blocked social networks as addicted employees can distract themselves on such sites, instead of focusing on work. In fact, studies show that British companies have lost billions of dollars per year in productivity because of social media addiction among employees.

Also, what you carelessly post on the Internet can come back to trouble you. Revealing (泄露) personal information on social sites can make users vulnerable (易受伤害的) to crimes like identity theft, stalking, etc. Many companies perform a background check on the Internet before hiring an employee. If a potential employee has posted something embarrassing on social media, it can greatly affect their chances of getting the job. The same holds true for our relationships too, as our loved ones and friends may get to know if we post something undesirable on social networks.

Social media has its advantages and drawbacks as each coin has two sides. It is up to each user to use social sites wisely to enhance their professional and social life, and exercise caution to ensure they do not fall victim to online dangers.

1. Paragraph 2 mainly shows that social networks ________.
A.help students finish their homeworkB.offer professionals good chances
C.benefit users in various waysD.guide users to make right choices
2. Faced with problems caused by social media, some companies ________.
A.forbid the use of social networks during work time
B.avoid posting embarrassing information
C.refuse to hire potential addicted employees
D.take legal action against the attackers
3. The main purpose of this passage is to ________.
A.share experiences in using social mediaB.remind people to wisely use social media
C.provide some advice on social problemsD.raise public awareness of social problems
4. Which of the following shows the development of ideas in this passage?
A.B.
C.D.
