2 . It happens in every disaster (灾难): For those in need, people often donate (捐赠) things that turn out to be more of a trouble.
Juanita Rilling remembers it happened in 1988 when she was a disaster expert trying to help people suffering from a hurricane (飓风) in Honduras. “One morning I received a call from one of our logistic operators (物流运营商), and he explained to me that there was a plane carrying medical supplies that needed to land,” says Rilling. “But the ground was full, with lots of donations that no one had required. The plane—full of needed supplies—had to find someplace else to go. And it ended up stopping everyone’s plans by about 48 hours, which is important time in a disaster.”
Rilling now runs the Center for International Disaster Information, which is trying to make sure things like that don’t happen again. So when Superstorm Sandy hit, Rilling’s group started a project to encourage money donation. “Even a small donation can make a big difference and can quickly become exactly what people affected by a disaster need most,” Rilling says. But despite this, donators do that over and over. About 60% of the things donated after a disaster couldn’t be used. Often it’s old clothing or food.
Meghan Hara, who deals with kind donations for the American Red Cross, says she knows that some people are careful with giving money. And she doesn’t think that the need to give something concrete (实物) should be completely stopped.
“Part of what people are doing is that they’re helping, and they’re trying to help. What we need to work out is how to effectively deal with that,” Hara says.

3 . Earlier this month, TikTok announced that it will be introducing screen time limits for the accounts of users aged under 18. Children under 13 will require a parent or guardian to type in a password to continue scrolling (滚屏) through their feed, and those aged 13-17 will be asked to set their own passwords when the viewing time goes beyond the limit.
Studies suggest that 30 minutes may be the sweet spot for social media use, where users are able to stay connected with friends and family and view entertainment. However, many other studies show that overly-heavy social media use can lead to a lot of problems, such as physical issues and depression.
By suggesting 100 minutes as a hard line where a password is required to be created by the user, TikTok is gradually making the standards clear as to what may be regarded as problematic social media habit in young people. Although these passwords for older teenagers can obviously be bypassed, they are a step in the right direction in encouraging children to use social media responsibly.
Also, parents who own their own TikTok accounts will be able to link with their children’s accounts, gaining additional, such as muting notifications (消息免打扰) and customizing time limits for different days in the week.
Algorithms (算法) that could tell parents if the child has been viewing dangerous material could soon be put into use. However, the difficulty in this is the amount of content available on the internet.
Ultimately, apps such as TikTok and Instagram will need to continue introducing more measures to improve online safety for children.
Lawmakers around the world are paying close attention to the effect social media has on the young, meaning that the development of new tools to improve its use will no doubt take place soon if big tech wishes to avoid additional legal issues.

4 . The first wave of concerns over artificial intelligence(AI)in 2023 appeared soon after New Year’s Day when classrooms reopened and schools from Seattle to Paris started blocking ChatGPT, a powerful software based on AI large language models, because teenagers were using it to do their homework.
The AI large language models behind such products as ChatGPT work by repeatedly guessing the next word in a sentence after having “learned” the rules from a huge amount of/human-written works. Although they often get facts wrong, their answers appear so natural that Keven, their inventors begin to worry about their possible use for spreading false information.
People became more worried when various AI products started to create not just texts but novel images, music and human voices, which threatened the livelihoods of anyone who writes, draws or sings for a living. It led to strikes by Hollywood writers and actors and legal challenges from artists and bestselling authors. Some of the most respected scientists even warned that the technology’s unchecked progress was possibly threatening human existence. “In the longer term, they might manage our attention,” pioneering AI scientist Fei Fei Lisaid. “They would tell us which video to watch, which book to read or whose communication to respond as AI technology’s abilities improve rapidly. They could be a very good assistant, but also with really big risks.”
Li hoped that 2023 is going to be a year for people to think about what Al is, how to use it and what the effects are — all the good, the bad and the ugly.
“It’s easy to forget that they are not the first wave of AI products. Computer vision techniques developed by Li and other scientists have helped sort through a huge database of photos to recognize objects and individual faces and guide self-driving cars. Speech recognition advances have made voice assistants like Siri and Alexa a normal thing in many people’s lives,” said Tom Gruber, co-founder of Siri Inc.

5 . Housing officials say that lately they are noticing something different: students seem to lack the will, and the skill, to deal with ordinary conflicts. “We have students who are mad at each other and they text each other in the same room,” says a teacher. “So many of our conflicts are because kids don’t know how to solve a problem by formal discussion.”
And as any pop psychologist will tell you, bottled emotions lead to silent discontent (不满) that can boil over into frustration and anger. At the University of Florida, emotional conflicts occur about once a week, the university’s director of housing education says, “Over the past five years, roommate conflicts have increased. The students don’t have the person-to-person discussions and they don’t know how to handle them.” The problem is most dramatic among freshmen; housing professionals say they see improvement as students move toward graduation, but some never seem to improve, and they worry about how such students will deal with conflicts after college.
Administrators guess that reliance on cell phones and the Internet may have made it easier for young people to avoid uncomfortable encounters. Why express anger in person when you can vent (发泄) in a text? “Things are posted on someone’s wall on Facebook like: Oh, my roommate kept me up all night studying,” says Dana Pysz, an assistant director at the University of California, Los Angeles. “It’s a different way to express their conflict to each other, consequently creating even more conflicts as complaints go public.” In recent focus groups at North Carolina State University, dorm residents said they would not even deal with noisy neighbors on their floor.
Administrators point to parents who have fixed their children’s problems in their entire lives. Now in college, the children lack the skills to attend to even modest conflicts. Some parents continue to interfere (干涉) on campus.

6 . Leah Brown aged 36 fell several hundred feet from Oregon’s highest mountain right before the eyes of a group of volunteer rescue workers who rushed to her aid and helped save her life.
The woman was coming down a popular path (小路) on Mt. Hood, about 70 miles east of Portland, on Saturday morning, according to the local police. Mt. Hood is the highest in Oregon, standing at around11.240 feet.
The fall was seen by members of Portland Mountain Rescue (PMR), a volunteer organization focused on helping people in mountainous areas. The group called 911 and rushed to the woman, providing medical care. They helped keep the woman warm for seven hours as the police worked to get her off the mountain safely. Finally, the woman was evacuated (转移) to a parking lot at 9:30 pm and taken to a hospital.
The climber, Leah Brown, said she didn’t know what caused her fall. “I can only guess it was either an ice tool or a crampon (冰爪) that didn’t land and stick like it should have, so I became detached from the mountain,” Brown said. “The thing I’d like to most stress is my appreciation for the members of PMR who evacuated me and took good care of me the whole time,” Brown added. “They saved my life. ”
In a statement after the rescue, PMR warned of the dangerous winter conditions at the mountain. “The short days and lower temperatures mean that the snow tends to be very hard and icy, and the conditions tend to be much steeper. Climbing the mountain in icy conditions is much more difficult,” the group said.

7 . For those of us who grew up watching Star Trek, exploring space has been about discovering strange new worlds. And there are plenty of worlds to explore in time, but we still need major technological advancements to reach planets that are light years away.
What we are doing in space today is providing unbelievable benefits right now, right here on Earth. From space, we can monitor, manage and care for our planet. Satellite-based sensors show us the short- and long-term effects of human activity on our environment. Many companies are using their interest in space to help solve problems here, from using hyperspectral imaging(高光谱成像), which enable us to map vegetation(植被) and rain forests, to microsatellites that provide global connectivity for the network of things.
My company, OneWeb, is focusing on what I believe is one of the world’s most important issues: the need for equal access to the Internet. The Internet has become our economic lifeblood. And yet, nearly half of the world’s population doesn’t have Internet access. Space is playing a key role in bridging this digital divide. OneWeb is launching 1,980 satellites to help bring Internet access to people everywhere, and our first production satellites are already flying in space and have shown very high download speeds.
Fiber and cable Internet access technologies already cover most financially viable(可行的) major cities. Similarly, these regions will also be the first to be served with 5G. Poor communities are the last to get connected, and without connectivity, those communities have no chance to lift themselves from poverty. OneWeb’s satellites will reach every community in the world and enable equal access to the Internet for the world’s less developed places.
Fifty years from the day when man first walked on the moon, we are still only approaching the possible. There will be tens of thousands of new satellites, space stations and factories in the coming years to bring advancements in communications, scientific research, monitoring the earth, exploring space and more. This is exciting, but we must take action carefully.

8 . 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.
1. When can children play games according to the new rules?| A．Between 8 p. m. and 9 p. m. On Friday. | B．Between 8 p. m. and 9 p. m. On Tuesday. |
| C．Between 10 p. m. and 11 p. m. On Saturday. | D．Between 10 p. m. and all p. m. On Thursday. |
| A．the new rules can stop children’s addiction to social media |
| B．companies are more responsible for kids ‘ obeying the rules |
| C．the new rules will help prevent children playing online games |
| D．parents play a greater part in limiting the time of online games |
| A．Design an advanced program. | B．Use facial recognition systems. |
| C．Set up real-name registration systems. | D．Borrow accounts of their older relatives. |
| A．Rules Limiting Short-video alps | B．Rules Limiting Video Game Time |
| C．Rules Banning Irrational Fan Culture | D．Rules Breaking Addition to Social Media |
9 . A shocking 53.6 million metric tons of electronic waste was discarded last year, a new UN-backed report has revealed. The report shows that e-waste is up by 21% from five years ago. This isn’t surprising, considering how many more people are adopting new technology and updating devices regularly to have the latest versions, but the report also shows that national collection and recycling strategies are nowhere close to matching consumption rates.
E-waste contains materials including copper (铜), iron, gold and silver, which the report gives a conservative value of $ 57 billion. But most are thrown away or burned rather than being collected for recycling. Precious metals in waste are estimated to be worth $ 14 billion, but only $ 4 billion-worth is recovered at the moment.
While the number of countries with national e-waste policies has grown from 61 to 78 since 2014, there is little encouragement to obey and a mere 17% of collected items are recycled. If recycling does occur, it’s often under dangerous conditions, such as burning circuit boards to recover copper, which “releases highly poisonous metals” and harms the health of workers.
The report found that Asia has the highest amounts of waste overall, producing 24.9 million metric tons (MMT), followed by Europe at 12 MMT, Africa at 2.9 MMT, and Oceania at 0.7 MMT.
But whose responsibility is it? Are governments in charge of setting up collection and recycling points, or should companies be responsible for recycling the goods they produce? It goes both ways. Companies do need to be held accountable by government regulations and have incentives to design products that are easily repaired. At the same time, governments need to make it easy for citizens to access collection points and deal with their broken electronics in a convenient way. Otherwise, they may turn to the easiest option — the landfill.

| A．It does harm to the workers’ health. | B．It lacks national policy support. |
| C．It hardly makes profits. | D．It takes too much time. |
| A．New technology should be used to update old devices. |
| B．Governments and companies should take responsibilities. |
| C．Non-poisonous metals had better be used in e-device. |
