19、 fear of novel coronavirus exposure in early March, 16-year-old sophomore Andrew Chen knew that things were not going to return to normal as quickly as some of his peers hoped.But still, the change from seeing his friends on the swim team during daily practices to learning alone at home was jarring.
20、 “I only have three years here at South, and it pains me to see one of them being wasted,” Chen said.The coronavirus has upended everyones lives, but for students, the disruption feels particularly acute. Schools closed and graduation ceremonies were canceled. Summer plans, like camps and internship
21、s, are up in the air.But right now, many students are trying to stay connected, struggling with misinformation, and figuring out the best ways they can help through online method.For Josh Harycki, 17, a senior student at the Shipley School in Philadelphia, the best way to contribute was to create a
22、“social distancing pledge” for young people.“I saw a lot of younger generations not paying attention,” he said. “They were still going out, hanging out with people. I thought that there had to be a way to reach younger folks, who were probably not watching the news.”Harycki launched a call to action
23、 on social media and then built a website with a map that tracked the locations of people whod signed the pledge. The site also shares links to accurate sources of information like the US Centers for Disease Control and Prevention.Harycki knows that his peers are worried they cant connect with their
24、 friends in the same way, so he created the social distancing pledge to stress that while everyone might be physically distant, theyre still connected.“Part of what were highlighting is that you might feel like youre the only one taking this seriously, but our map shows that youre not alone,” he sai

After months of testing an option to hide likes in select international markets, Instagram, which is owned by Facebook (FB), h
29、as already been testing hiding likes in seven other countries, including Canada, Ireland and Australia. For years, likes have been central to how celebrities, brands, politicians and everyday users experience Instagram and Facebook. Its a way of measuring popularity and success. But in recent months
30、, Instagram has been rethinking how likes contribute to making its platform more toxic. Now its considering a change.The total number of likes on posts which appear as hearts on the app will disappear from Instagrams main feed, profile pages and permalink pages. The owner of the account can still se
31、e their own likes, but their followers wont know the count.CNN Business previously spoke with users in countries with the test. The majority felt this move would improve well-being on the app. Instagram is the most detrimental social networking app for young peoples mental health, such as negatively
32、 impacting body image, according to one study.But other users and psychologists said hiding likes wont fix everything. The test doesnt address some of the key ways that activity on Instagram can impact the well-being of users, including bullying, feeling left out and thinking other peoples lives are
33、 better than their own.Renee Engeln, a psychology professor at Northwestern University, voiced his opinion that the biggest impact of Instagram is the content and the exposure to this constant stream of perfected images is what seems to hurt psychologically.

Like our sun, stars are unbelievably hot furnaces that burn their own matter as fuel. When most of the fuel is used
37、 up, the star begins to die.The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.After the explosion gravity pulls in whats left of the star. As the outside of the star sinks towar
38、d the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billions of pounds.The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the
39、 gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can flee. The star becomes black when there is no light. Then a black hole is born!Thats what we know about black holes. What we dont know i
40、s this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.But if the black hole doesnt keep shrinking, what happens to it? Some scientists think black holes are like doorways to

In other words, a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly somewhere else. But where? A dif

Nothing we know of could go into a black hole without being crushed. So, for the time being, black holes mostly remain a mystery.Black holes are a mystery but that hasnt
43、stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earths energy needs, with plenty to spare. Another scientist wondered if a black hole could someday be used to swallow earthly waste a sort

48、m an evolutionary advantage, according to Austrian zoologist Konrad Lorenz. 37 When we look at babies, we are attracted to certain facial features. These features make us want to take care of them so they can grow up healthily and pass their genes on to the next generation.Looking at baby animals an
49、d cartoon characters also cause these feelings.

86、ow they will deliver it.Text 10W: Good morning, boys and girls. Today Id like to continue our discussion of early American agriculture, moving on from growing crops to raising farm animals. The animals on a typical Massachusetts farm in the early 1800s would look quite different from the ones in the
87、 1980s. In those times, settlers brought cattle and sheep with them to America from various parts of Europe. Sadly, most of the younger animals died because the settlers were busy building houses and planting crops. Hence, they had little time to care for their animals. As the remaining livestock gr
88、ew, they provided the settlers with meat, milk and wool. All of these were very important to 19th century farming families, as they could be traded for items they couldnt produce. Nowadays, the survival of farm animals has greatly improved. Feeding is now more selective and specialized: some animals are bred for meat, others for their milk and some for their wool.
