1 . Digital reading (数字阅读) appears to be destroying habits of “deep reading”. Astonishing numbers of people with years of schooling are in fact illiterate (文盲). This month’s Ljubljana Manifesto (宣言) explains: “The digital field may promote more reading than ever in history, but it also offers many attractions to read in a casual and scattered (零散的) manner— or even not to read at all. This increasingly endangers higher-level reading.”

That’s frightening, because “higher-level reading” has been necessary to civilization. It made the understanding and an international increase in empathy (共鸣). Without it, we would suffer a lot. As the Ljubljana Manifesto notes, “as much as one-third of Europeans struggle even with lower-level reading skills.” More than one-fifth of adults in the US “fall into the illiterate/functionally illiterate category”. Separately, post-pandemic (后疫情时期) reading scores for American13-year-olds are the lowest in decades. And the Washington-based Center for Global Development recently estimated that literacy (读写能力) in South Asia and sub-Saharan Africa among those with five years of schooling has decreased by 10% this past half century.

Experts in the Ljubljana Manifesto record the demerits of digital reading: “Recent studies of various kinds indicate a decline of thoughtful reading, slow reading and long-form reading.” When you read a book on paper, you can be entirely inside the experience, absorb hundreds of pages of details thoroughly and begin to catch the world’s complexity. Online, says Maryanne Wolf of UCLA, we are “skimming, scanning and scrolling”. The medium is the message: doing deep reading on your phone is as hard as playing tennis with your phone. Recently, a bright 11-year-old boy told me I was wasting time on books: he absorbed more information faster from websites. He had a point. But digital readers also absorb more misinformation and seldom absorb fine opinions.

In short, as professors from Northwestern University predicted in 2005, we are returning to the days when only an elite (精英) “reading class” reads long texts, which is worrying.

2 . In the rich countries of the West, the electric vehicle revolution is well occurring. Climate-conscious consumers drive Teslas or Polestars for reasons of morality (道德) and fashion. Poorer countries are also experiencing a wave of electrified trend. In Bangladesh, electric three-wheeler taxis, known as tuk-tuks, are rapidly replacing gas-powered ones on the streets. Such electric vehicles are climate friendly, cost effective, and help reduce air pollution.

Yet a glance under the hood (引擎盖) of these vehicles shows a poisonous secret: each tuk-tuk runs on five massive lead-acid batteries (铅酸电池), containing almost 300 pounds of lead (铅) in total. Every year and a half or so, when those batteries need to be replaced and recycled, about 60 pounds of lead leaks into the environment. Battery recycling, often at small-scale unregulated factories, is a highly profitable (高利润的) but deadly business.

Lead is dangerous, and any exposure to it is harmful to human health. Lead that has entered the environment hurts people on an unexpected scale. The numerous ways lead enters air, water, soil, and homes across the developing world and the enormous damage it does to human health, wealth, and welfare cause one of the biggest environmental problems in the world yet receives little attention.

The World Bank estimates that lead kills 5.5 million people per year, making it a bigger global killer than AIDS, malaria, diabetes, and road traffic deaths combined. On top of the shocking deaths, the social burden of lead poisoning is heavy, as is its contribution to global inequality — our research on the cognitive (认知的) effects of lead poisoning suggests that it may explain about one-fifth of the educational achievement gap between rich and poor countries.

But unlike many challenges faced by developing countries, lead poisoning is a problem that can be resolved through financial investment (财政投入). Better monitoring, research, and rules can help protect children all over the world from the unpleasant effects of lead poisoning and reduce the massive global costs it brings.

4 . In the days before the Internet, critical thinking was the most important skill of informed citizens. But in the digital age, according to Anastasia Kozyreva, a psychologist at the Max Planck Institute of Human Development, and her colleagues, an even more important skill is critical ignoring.

As the researchers point out, we live in an attention economy where content producers on the Internet compete for our attention. They attract us with a lot of emotional and eye-catching stories while providing little useful information, so they can expose us to profit-generating advertisements. Therefore,we are no longer customers but products, and each link we click is a sale of our time and attention. Toprotect ourselves from this, Kozyreva advocates for learning the skill of critical ignoring, in which readers intentionally control their information environment to reduce exposure to false and low-quality information.

According to Kozyreva, critical ignoring comprises three strategies. The first is to design ourenvironments, which involves the removal of low-quality yet hard-to-resist information from around. Successful dieters need to keep unhealthy food out of their homes. Likewise, we need to set up a digital environment where attention-grabbing items are kept out of sight. As with dieting, if one tries to bank onwillpower not to click eye-catching “news”, he’ll surely fail. So, it’s better to just keep them out of sightto begin with.

The next is to evaluate the reliability of information, whose purpose is to protect you from false and misleading information. It can be realized by checking the source in the mainstream news agencies which have their reputations for being trustworthy.

The last goes by the phrase “do not feed the trolls.” Trolls are actors who internationally spread false and hurtful information online to cause harm. It may be appealing to respond to them to set the facts straight, but trolls just care about annoying others rather than facts. So, it’s best not to reward their bad behaviour with our attention.

By sharpening our critical ignoring skills in these ways, we can make the most of the Internet while avoiding falling victim to those who try to control our attention, time, and minds.

5 . Languages have been coming and going for thousands of years, but in recent times there has been less coming and a lot more going. When the world was still populated by hunter-gatherers, small, tightly knit(联系) groups developed their own patterns of speech independent of each other. Some language experts believe that 10,000 years ago, when the world had just five to ten million people, they spoke perhaps 12,000 languages between them.

Soon afterwards, many of those people started settling down to become farmers, and their languages too became more settled and fewer in number. In recent centuries, trade, industrialisation, the development of the nation-state and the spread of universal compulsory education, especially globalisation and better communications in the past few decades, all have caused many languages to disappear, and dominant languages such as English, Spanish and Chinese are increasingly taking over.

At present, the world has about 6,800 languages. The distribution of these languages is hugely uneven. The general rule is that mild zones have relatively few languages, often spoken by many people, while hot, wet zones have lots, often spoken by small numbers. Europe has only around 200 languages; the Americas about 1,000; Africa 2,400; and Asia and the Pacific perhaps 3,200, of which Papua New Guinea alone accounts for well over 800. The median number(中位数) of speakers is a mere 6,000, which means that half the world’s languages are spoken by fewer people than that. Already well over 400 of the total of 6,800 languages are close to extinction(消亡), with only a few elderly speakers left.

8 . Today’s grandparents are joining their grandchildren on social media, but the different generations’ online habits couldn’t be more different. In the UK the over-55 s are joining Facebook in increasing numbers, meaning that they will soon be the site’s second biggest user group, with 3.5 million users aged 55-64 and 2.9 million over-65s.

Sheila, aged 59, says, “I joined to see what my grandchildren are doing, as my daughter posts videos and photos of them. It’s a much better way to see what they’re doing than waiting for letters and photos in the post. That’s how we did it when I was a child, but I think I’m lucky I get to see so much more of their lives than my grandparents did.”

Interestingly, Sheila’s grandchildren are less likely to use Facebook themselves. Children under 17 in the UK are leaving the site - only 2.2 million users are under 17 -but they’re not going far from their smartphones. Chloe, aged 15, even sleeps with her phone. “It’s my alarm clock so I have to,’ she says. “I look at it before I go to sleep and as soon as I wake up.”

Unlike her grandmother’s generation, Chloe’s age group is spending so much time on their phones at home that they are missing out on spending time with their friends in real life. Sheila, on the other hand, has made contact with old friends from school she hasn’t heard from in forty years. ”We use Facebook to arrange to meet all over the country,” she says. “It’s changed my social life completely.”

Parents have an important role to play if they want their kids to spend more time in real life. Peter, 38, who spends most of his time in front of a screen, is recently determined to set a better example to his kids. In the evening or at weekends, he would leave his smartphone home and take his kids out to nature.

The European Union is     1     organization of European countries. The countries are     2     (depend) and are governed in different     3     (way). In the United Kingdom,     4     example, the head of state is a king or queen. In France, on the other hand, the head of state is a president. But each of them     5     (send) representatives to the European Parliament,     6     has some control over what happens in each of the member countries.

The idea of the European Union     7     (begin) in the 1950s. The first members were France, Germany, Belgium, Luxembourg, the Netherlands and Italy. Little by little, the number increased during the second half of the     8     (twenty) century. By the year 2000, there were 15 member countries. The new countries were Austria, Denmark, Finland, Greece, Ireland, Portugal, Spain, Sweden and the United Kingdom.

In 2004, the European Union increased to 25 members. The Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, the Slovak Republic and Slovenia, plus the Mediterranean islands of Cyprus and Malta all became members. The     9     (expand) European Union has a population of more than half a billion people, twice     10     big as the population of the United States.
