1 . Twelve-year-old Catherine has a lot of friends—632, actually, if you count up her online friends. And she spends a lot of time with them.
But is it possible that Catherine’s online friendships could be making her lonely? That’s what some experts believe. Connecting online is a great way to stay in touch, they say. However, some experts worry that many kids are so busy connecting online that they might be missing out on true friendships.
Could this be true? During your parents’ childhoods, connecting with friends usually meant spending time with them in the flesh. Kids played Scrabble around a table, not words with friends on their phones. When friends missed each other, they picked up the telephone. Friends might even write letters to each other.
Today, most communication takes place online. A typical teen sends 2,000 texts a month and spends more than 44 hours per week in front of a screen. Much of this time is spent on social media platform.
In fact, in many ways, online communication can make friendships stronger. “There’s definitely a positive influence. Kids can stay in constant contact, which means they can share more of their feelings with each other,” says Katie Davis, co-author of The App Generation.
Other experts, however, warn that too much online communication can get in the way of forming deep friendships. “If we are constantly checking in with our virtual world, we will have little time for our real-world friendships,” says Larry Rosen, a professor at California State University. Rosen also worries that today’s kids might mistake the “friends” on the social media for true friends in life. However, in tough times, you don’t need anyone to like your picture or share your blogs. You need someone who will keep your secrets and hold your hand. You would like to talk face to face.

2 . Binge-watching (刷剧) is when a person watches more than one episode of a show in a row. With developments in the speed and connectivity of the Internet, increases in technology and the rise of on-demand entertainment companies, people can now have their favorite shows stream (流播) directly to their television at their convenience.
This behavior is nothing new. In fact, binge-watching has been officially listed in dictionaries since 2015. The entertainment companies recognize this behavior and many take steps to encourage it. Often, instead of releasing each episode on a week-by-week basis, an entire series will become available concurrently. Once the episode finishes, many platforms will display pop-ups with “you might like” suggestions, or will automatically play the next episode.
However, recent research suggests that out of the more than half of British adults who watch more than one episode of a show back-to-back (一集接一集地), almost a third have admitted missing sleep or becoming tired as a result; and 25% have neglected their household chores (家务活). Next we’ll be missing work!
Bingeing has other connections — binge eating, binge drinking and binge smoking. All of them are often associated with a lack of control and a possible route to addiction. Lindsey Fussell, consumer group director, said, “The days of waiting a week for the next episode are largely gone, with people finding it hard to resist (抗拒) watching multiple episodes around the house or on the move.” If people find binge-watching hard to resist, are we witnessing the birth of a new type of addiction?
The countless number of information and entertainment that television and online media can bring us is, many would say, a good thing. However, when the activity begins to bleed into other areas, causing us to stop functioning, then it becomes a problem. So, what’s the answer? Moderation! Neither a tiny amount, nor too much. After all, as the old proverb says, “A little of what you fancy does you good.”

3 . China has set new rules limiting the amount of time children can play online games. The rules limit children to just three hours of online game playing a week. That is one hour between 8 p. m. and 9 p. m. on Friday, Saturday and Sunday most weeks.
Li Zhanguo has two children aged 4 and 8. Even though they do not have smartphones, they enjoy playing online games. Like many other parents. Li is happy with new government rules. But experts say it is unclear if such policies can help prevent addiction to online games. Children might just get addicted to social media instead. In the end, experts say, parents should be the ones to set limits and support good practice.
There has been a growing concern in China about gaming addiction among children. Government reports in 2018 found that about one in ten Chinese children were addicted to the Internet. The new rules are part of an effort to prevent young people from spending too much time on unhealthy entertainment. That includes what officials call the “irrational fan culture”
Under the new rules, the responsibility for making sure children play only three hours a day as largely on Chinese gaming companies like Net Ease and Ten cent. Companies have set up real-name registration systems to prevent young users from going past game time limits. They have used facial recognition technology to check their identities. And they have also set up a program that permits people to report what is against the law. It is unclear what punishments gaming companies may face if they do not carry out the policies. And even if such policies are performed, it is also unclear whether they can prevent online addiction.
A specialist treating Internet addiction expects about 20 percent of children will find ways to break the rules by borrowing accounts of their older relatives and find a way around facial recognition. In his opinion, short-video alps such as Douyin and Kuaishou are also very popular in China. They are not under the same restrictions as games.

4 . Are you happy with your appearance?
“Almost all the girls with single-fold eyelids (单眼皮) in our class have had double eyelid operations,” Zeng, a Senior 2 student from Chengdu, told Xinhua. Zeng had the same surgery done this summer.
From popular photo-editing apps to plastic surgery (整形手术), it seems that large eyes, pale skin and a skinny body are the only standard for beauty these days. But can following this standard really make us feel good about ourselves?
“Many teenagers are upset about their appearance because they believe in unrealistic standards of beauty,” experts say.
However, trying to live up to strict standards can make us feel anxious. What troubles us is not just our “imperfect” looks, but the fact that we criticize ourselves too much.
| A．Beauty comes in all shapes and sizes. |
| B．Body image anxiety is common among teenagers. |
| C．Guys care just as much as girls do about their body image. |
| D．Some teenagers might feel negative about their appearance. |
| E．It’s common for teenagers to feel confident about their appearance. |
| F．She and many of her classmates believe bigger eyes look more beautiful. |
| G．Perfect faces and bodies are everywhere in advertising, TV shows and social media. |
5 . The rate of childhood obesity in the U. S. has tripled over the past 50 years. The American Academy of Pediatrics (AAP) made waves this year by recommending that doctors put obese kids as young as two years old on intensive, family-oriented lifestyle and behavior plans. It also suggested prescribing weight-loss drugs to children l2 and older and surgery to teens 13 and older. This advice reflects the organization’s adoption of a more active position on childhood obesity.
Yet the lifestyle programs the AAP recommends are expensive, inaccessible to most children and hard to maintain. Few weight-loss drugs have been approved for children. And surgery has potential risks and few long-term safety data. Furthermore, it’s not clear whether interventions in youngsters help to improve health or merely add to the psychological burden overweight kids face from the society.
Rather than paying close attention to numbers on a scale, the U. S. and countries with similar trends should focus on an underlying truth: we need to invest in more and safer places for children to play where they can move and run around, climb and jump, ride and skate.
Why is it so hard to get kids moving? Experts blame the problem on the privatization of sports — as public investment in school-based athletics dwindles, expensive private leagues have grown, leaving many kids out. In addition to fewer opportunities at school, researchers cite increased screen time and a lack of safe places for them to play outside the home. New York City, for example, had 2,067 public playgrounds as of 2019 — a very small amount for its large population. In Los Angeles in 2015, only 33 percent of youths lived within walking distance of a park.
Kids everywhere need more places to play. Public funding to build and keep up these areas is crucial, but other options such as shared-use agreements can make unused spaces available to the public. These opportunities aren’t primarily about changing children’s waistlines — they’re how we keep childhood healthy and fun.

6 . America’s youth is turning its back on tobacco. According to a study recently published by the Centers for Disease Control and Prevention (CDC), cigarette smoking among US high school students is at an all-time low. One in 5 US high school students in 2016 reported using a tobacco product within the past 30 days, an improvement from 1 in 4 students just one year before.
“These findings show the importance of continuing to implement the evidence-based strategies that we now work to reduce all forms of tobacco product use, including e-cigarettes, among our nation’s youth,” says Brian King, of the CDC’s Office on Smoking and Health and senior author of the study.
And it’s not just tobacco: Drug use among US teens is down across the board. The National Institute on Drug Abuse has published annual reports on US teens’ drug use since 1996, and the 2016 survey shows the lowest rates of illegal drug and alcohol use. Marijuana (大麻) use remained “mostly steady”. “It is encouraging to see more young people making healthy choices not to use illegal substances,” says former National Drug Control Policy Director Michael Botticelli.
All individual forms of tobacco such as cigarettes, e-cigarettes, cigars, and smoke-less tobacco saw declines in usage in 2016. Experts are especially encouraged by the decline in cigarettes, the most popular tobacco product among teens. In 2016, 11.3 percent of high school students reported using e-cigarettes, down from 16 percent in 2015.
Dr. King says adaptation is key to the decline of e-cigarettes. “We have over a half-century of science telling students about the harmful effects of tobacco use and what works best to prevent it,” says King. “E-cigarettes are the most commonly used tobacco product among our nation’s youth, and it’s critical that our proven strategies are modernized to keep pace with the changing tobacco product landscape.”

7 . Everywhere I look, there are new buildings under construction. The neighborhoods that I knew as a boy, filled with beautiful old buildings, have mostly disappeared, and in their place, modern, high-rise buildings have appeared. There is good reason for this. Residents want all the conveniences of modern living. However, how can our children understand and maintain their cultural identity if we erase so much of the physical evidence of it?
The arguments for preserving historic buildings are not simply about an emotional attachment to the past. There are also good economic arguments in favour of preservation. The renovation (修缮) and preservation of historic districts can become an economic engine, drawing tourists and small businesses to the area. For example, in Dubai, the historic Al Bastikiya district draws thousands of tourists every year from all over the world. It also attracts local residents, eager to learn about their city's past.
Some have argued that historic preservation is too expensive, but many recent projects have demonstrated that this is not necessarily the case. In fact, renovation of an existing structure for adaptive reuse can cost about £40 per square metre less than even the most basic new construction, while preserving the beauty of the original building. And, although it is often claimed that old buildings have a more significant environmental footprint than new construction because they aren’t very energy efficient, architects and environmental experts maintain that the greenest building is the one that is already built. New construction almost always has a more serious environmental impact (影响) because it requires the use of all-new materials that must be transported, often over long distances, instead of recycled materials that are already on site. We recycle so many other things. We can and should recycle buildings, too.
Historic preservation is an option that opens many possibilities; demolition (拆毁), in contrast, is irreversible. Once these treasures are lost, they are lost forever, an important link in our heritage that can never be recovered.
1. What drives people to replace old buildings with new ones?| A．Their dislike of old buildings. | B．Their pride in cultural identity. |
| C．Their concern about young generations. | D．Their desire for modern comforts. |

8 . 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.

9 . The world food safety could be in danger because of a number of food production shocks (冲击), according to an Australian study.
The researchers from the University of Tasmania found that there were 226 shocks in the area of food production across 134 nations and the frequency has been increasing over the past 50 years.
According to Cottrell, a researcher from the University of Tasmania, the main causes behind the shocks are different. For crops, extreme weather events such as floods and no rain for a long time play the biggest part. Weather also plays a role in livestock(家畜)production, but disease plays a bigger role. Disease also leads to aquaculture(水产业)shocks, while in the ocean most of the food shocks are caused by overfishing.
“When we look at the food production systems, covering crops, livestock, fisheries and aquaculture,” Cottrell said, “we find that crops and livestock are more easily affected than aquaculture. And some countries in South Asia are more frequently affected than others.”
The effects of production shocks reached far away from where they happened. When one means of food production is greatly reduced, it will cause unexpected results. “The India got a lot of food production shocks in crops and livestock, largely because of floods,” Cottrell explained. “If countries like India are shocked and the rice production is much smaller, they’ll probably send less goods to another country. And that shock suddenly starts to affect all the trade partners of the major producers as well.”
According to what Cottrell said, while the international community faces a great challenge to these problems, steps taken now can help fight against unexpected shocks in the future. “This can be done through measures such as food store systems so that they are better able to deal with the effect which is caused by problems such as climate change.” said Cottrell.

10 .
Chen Chen is 8 years old. For the Spring Festival this year he was given an iPad as a present and never goes anywhere without it.
Many children in China are suffering the same problem:
“There are about 30 shortsighted children coming every day,” said Hu Dali, a doctor at Guiyang Aier Eye Hospital. “Half of those children are suffering from reduced vision because they have played with mobile phones and iPads for too long.”
Experts say children’s version is not yet fully developed and their eyes get tired more easily.
The iPad uses a very bright LED backlight. A user’s pupils (瞳孔) have to keep getting used to the new light levels. If children stare at an iPad screen for a long time, their eyes do not have time to rest.
Experts suggest that users should hold their iPad between 40—60 centimeters away from them. The brightness of the screen should be made comfortable for children. Parents should also stop their children from using an iPad for more than one hour every day.
