【推荐1】Supporters of education technology have always imagined the bright future in the past twenty years: that by 2019, half of all middle school courses would be online; videos and practice apps could let students learn maths at their own speed; or that students with internet-connected computers could learn anything without the help of schools or teachers.

Then in 2020, 1 billion students around the world turned to online learning as the pandemic( 疫情) shut down schools. It was education technology’s big moment, but for many students and families, online learning has been a disappointment. When the world needs it most, why has education technology seemed so lackluster?

Technology education has a long history, but throughout the history there have been two main challenges. The first is that most people depend on human connection to stay motivated. When a student fails to concentrate on what the teacher is saying in a classroom, the teacher can notice it and take action. But when the same thing happens while using an education technology product, no one can see it. Assessments(评价) are also a challenge. Computers can show students standard answers. In some subjects, like maths, education technology can immediately tell whether the answer is right. But if we ask students to write a passage that explains why the Second World War broke out, computers can not assess the answer, part of which may be incorrect.

Education technology has long promised to change education, but for large areas of school learning, we don’t have online tools that are any better than printed books. For most teachers, the road to successful teaching with technology is not a total change to traditional education, but a slow process towards finding a right tool or way that is suitable for students.

【推荐2】In the space of just two years, the app Douyin, created by Beijing-based company ByteDance, has gathered more than half a billion users—around 40%of them outside China—who share short videos of themselves lip-syncing (假唱), cooking, dancing or just being silly. What sets ByteDance apart is its success in the social media category, which is controlled by Facebook, Twitter and Snap—all Western companies.

ByteDance calls itself an artificial intelligence company. It uses machine learning and algorithms (算法) to figure out what people like most and give them more of what they want to see. On Douyin, people can edit and beautify 15-second videos before posting them online. The app has even made a phrase to describe people glued to their customized feeds: "shua Douyin" or "scrolling through Douyin". Last year, the company released TikTok, the overseas version of Douyin. ByteDance's growing video empire has made it the world's fifth biggest app maker. ByteDance says TikTok and Douyin together have more than 500 million monthly active users.

Investors like ByteDance because its hundreds of millions of users attract a lot of advertising money. The video apps are lucrative because they attract a lot of users in their teens and 20s, who are more generous with the money ByteDance also makes money through income sharing deals. People on TikTok, for example, can buy digital coins to give to other people on the app-like throwing money in a performer's tip jar. ByteDance takes a cut of those earnings.

ByteDance's founder and CEO is Zhang Yiming, a 35-year-old former Microsoft employee. People who have worked with Zhang describe him as someone who thinks deeply about technology and spends much of his free time writing code.

Like Facebook and Twitter, ByteDance is also battling fake news and inappropriate content. ByteDance promises to add thousands more employees to review the content on Douyin.

1. What makes ByteDance so special?

A．It has controlled Facebook, Twitter and Snap.

B．It invented the social media app initially in the world.

C．It is the biggest artificial intelligence company on the earth.

D．Its app challenges similar companies' rule in the Western world.

2. Why is Douyin so popular?

A．It has both home and overseas version.	B．It is a new generation hi-tech product.
C．It meets the demand of people individually.	D．It is easy and totally free to operate online.

3. How does ByteDance mainly make a profit?

A．By charging the users.	B．By charging the advertisement.
C．By forcing the users to donate.	D．By selling its artificial intelligence.

4. What can be the best title for the text?

A．TikTok Is Popular Overseas	B．Competition among Social Media
C．ByteDance Is Battling Fake News	D．Douyin, a Popular APP

【推荐1】What is the future of AI (人工智能)? Will it be a good thing? We asked four students what they think.

Liu Lei	I think AI will be more useful in our future lives. It’s now used in many fields, like phones and medicine. No one really knows what will happen if machines become smarter than humans. However, I’m sure AI will help us solve many problems.
Xu Lu	I’m worried that people create something that can be better than themselves. In the near future, AI will develop at a high speed. Humans may be replaced (取代) because AI robots will do a lot of work instead of people.
Zhao Mingming	I really think that Al will change the way we work, the way we live, and the way we think. Imagine if we could put a CPU into our brains! Soon we’ll be able to improve our math and memory. How exciting!
Molly	Think of what’s happening now. Some robots are used to kill animals. So I think AI will be very dangerous for humans, too. We need to be careful about what we ask machines to do.

【推荐2】Welcome to your future life!

You get up in the morning and look into the mirror. Your face is firm and young­looking. In 2035, medical technology is better than ever. Many people at your age could live to 150, so at 40, you're not old at all. And your parents just had an anti­aging (抗衰老的) treatment. Now, all three of you look the same age!

You say to your shirt, "Turn red." It changes from blue to red. In 2035, "smart clothes" contain particles (粒子) much smaller than the cells in your body. The particles can be programmed (编程) to change your clothes' color or pattern.

You walk into the kitchen. You pick up the milk, but a voice says, "You shouldn't drink that!" Your fridge has read the chip (芯片) that contains information about the milk, and it knows the milk is old. In 2035, every article of food in the grocery store has such a chip.

It's time to go to work. In 2035, cars drive themselves. Just tell your "smart car" where to go. On the way, you can call a friend using your jacket sleeve. Such “smart technology" is all around you.

So will all these things come true? "For new technology to succeed," says scientist Andrew Zolli, "It has to be so much better that it replaces what we have already." The Internet is one example—what will be the next?

【推荐1】Polar bears have captivated(迷住) humans since the beginning of recorded time. Writings dating back to 57 C. E. in ancient Rome describe flooded amphitheatres where polar bears and seals competed against each other ( not much of a fight, as it turns out). Kings of ancient Egypt and early Norway were the first to keep polar bears captive, and the fascination with them has held through the centuries. Ad campaigns all over the world feature polar bears to sell everything from bottled water to transportation systems to soda.

A Coca-Cola ad campaign in the 1990s added "adorable" to the polar bear's image. The ads featured a clumsy, animated cub that bridged the natural wariness between polar bears and penguins to share a nice, cold bottle of Coke. Polar bears don't actually have a natural affinity for penguins, as the two don't live in any of the same regions and never see each other. But still, cute is cute.

Polar bears' shocking whiteness, ferocity and sheer size make them icons of purity and power. Males can grow up to 10 feet tall (3 meters) and weigh up to 1,500 pounds (680 kilograms). A single bear can take on a 2,500-pound walrus, and hang on to the massive catch with 2-inch claws (5 centimeters). They walk hundreds of miles across ice sheets every winter, following their prey.

In the Arctic, polar bears are at the top of the food chain, and it’s not just because of their size. They're so well-adapted to their environment that they experience no change in body temperature at minus 34 degrees Fahrenheit ( minus 37 Celsius). However, the incredible survival mechanisms that let them thrive in frigid winters may prove to be their undoing. Because of global warming, winters are getting less cold and polar bears are dying. Some scientists project that if climate trends continue, 30 percent of the current polar bear population will be wiped out by 2050. What’s life like for an animal that needs such extreme cold to survive? Let's head to the Arctic and see how polar bears live on the ice.

1. What does the underlined word in the first paragraph refer to?

A．A place for fighting.	B．A place for entertainment.
C．A place for eating.	D．A place for jogging.

2. Which of the followings about polar bears is NOT true?

A．They have a close relationship with penguins.

B．They are favored by ad campaigns.

C．They will walk hundreds of miles to follow their prey.

【推荐2】Teens who have good, supportive relationships with their teachers enjoy better health as adults, according to a research.

“This research suggests that improving students’ relationships with teachers could have important, positive and long-lasting effects beyond just academic success,” said Jinho Kim, the author of the study. “It could also bring about important health benefits in the long run.”

Previous research has suggested that teens’ social relationships might be linked to health outcomes in adulthood—perhaps because poor relationships can lead to chronic stress which can raise a person’s risk of health problems over the lifespan, according to Kim. However, it is not clear whether the link between teen relationships and lifetime health is certainly cause and effect—it could be that other factors, such as different family backgrounds, might contribute to both relationship problems in adolescence and poor health in adulthood. Also, most research has focused on teens relationships with their peers, rather than on their relationships with teachers.

To explore those questions further, Kim analyzed data on nearly 20,000 participants from the Add Health study, a national study that followed participants for 13 years, from seventh grade into early adulthood. The participants included more than 3, 400 pairs of brothers and sisters. As teens, participants answered questions, like “How often have you had trouble getting along with other students?” “How much do you agree that friends care about you?” “How often have you had trouble getting along with your teachers?” and “How much do you agree that teachers care about you?” As adults, participants were asked about their physical and mental health. Researchers also took measures of physical health, such as blood pressure and BMI (体质指数).

Kim found that, as expected, participants who had reported better relationships with both their peers and teachers in middle school and high school also reported better physical and mental health in their mid-20s. However, when he controlled for family background by looking at pairs of brothers and sisters, only the link between good teacher relationships and adult health remained significant.

The results suggest that teacher relationships are even more important than previously realized and that schools should invest in training teachers on how to build warm and supportive relationships with their students, according to Kim.

1. According to paragraph 3, we can know that ________.

A．teen relationships with teachers were not studied before.

B．family background is the main factor in improving mental health.

C．teen relationship is not the only factor that affects the lifetime health.

D．relationship problems in adolescence can cause poor health in adulthood.

2. What is paragraph 4 mainly about?

A．How the research was done	B．What questions were explored
C．How physical health was measured	D．What kind of participants were studied

3. According to Kim’s findings, we can infer that ________.

A．Good adult health depends on teens’ good teachers.

B．More attention should be paid to the students relationships with teachers.

C．The importance of student-teacher relationships was fully realized before.

D．Participants reported better relationships with their teachers and better health as adults.

4. Where does this text probably come from?

A．A. family survey	B．A medical report

【推荐3】Our teenagers are lonely. A new study by Harvard’s Making Caring Common (MCC) shows just how that feeling has been common and become serious during the past year when we had to keep the social distance. One year’s online learning and life in the bedrooms rather than the classrooms or dorm (宿舍) rooms can make teenagers feel lonelier than before. Teenagers have been more likely to be influenced by loneliness than older adults.

Experiencing loneliness is certainly sad, but it is also dangerous. Researchers found that 63% of the young were suffering from bad sleep, anxiety, and poor health during the lockdown (封闭) and that nearly a quarter had started or increased some bad habits, including smoking, drinking and staying up late to deal with their feelings.

About half of the young people in the study, who said they had felt lonely, explained that over the past weeks not one person had taken more than just a few minutes to ask how they had been lately. It made them feel they had no one who really cared about them. Their parents thought they had much free time after lessons and it seemed that they only worried about whether their children could perform their schoolwork at the level they once did. They didn’t know the problem.

Sian Leah Beilock, the president of Barnard College, explains that young people depend on social media, which makes them especially weak to social media’s harm. She also suggests that fewer close friends may explain some of the feelings of loneliness. She reports that in 1986 the average American had three close friends with whom they could share important things about their lives. In 2005, that number had dropped to just two friends. And in 2020, one in five millennials (千禧一代) had no friends at all.

These levels of loneliness are heartbreaking. MCC suggests, as a nation, we first should focus on teaching the young to make meaningful connections between people and support them.
