【推荐1】Have you ever wondered what an American high school is really like?     1    

A typical American high school has several large buildings and enough space for about 1,500 students.     2    When students first arrive at school, they go straight to their lockers to put away or get their textbooks and to hang up their outdoor clothes. As American textbooks are expensive, students would rather rent than buy them.    3    

American students have different types of school transport. They usually take a yellow school bus or walk to school if they live close enough.    4     When they turn 16 years of age, most take a free driving class at school for one term. If students earn passing grades in the class and also pass their state driver’s exam, they can begin driving themselves to school.

    5    They must take science, math, English and social studies. They can choose art, homemaking, fashion design and other classes. In some schools students are required to take one or more of the following special classes: health education, physical education or foreign language studies. Students move to different classrooms for each subject. This is because each teacher has their own classroom. There is a five-minute break between classes, to give the students the time to hurry to their next class.

The regular school day usually ends early in the afternoon. After school more than half of the students are involved in after-school activities. These activities include sports-especially football, basketball, baseball and soccer or clubs, such as yearbook, speech, school newspaper, photograph or student government.

【推荐1】A 10-year-old swimmer with sky-high dreams and a name to match them has broken a record previously held by Olympian Michael Phelps.

Clark Kent Apuada, whose friends call him “Superman”, swam the 100-meter butterfly in 1: 09. 38 at the Far Western Long Course Championships in his home state of California this Sunday. That’s a second faster than the record Phelps set at the same event in 1995 with a time of 1: 10. 48 in the same category of boys under 10.

Clark, a rising fifth-grader who is Filipino-American, told HuffPost he’s been dreaming about breaking Phelps’ record ever since he started swimming competitively at age 7. “I was so motivated,” Clark said about his win. “I was so happy that I was able to beat that record.”

Phelps competed in his first Olympics at age 15. He went on to become the most decorated Olympian in history, with 28 medals overall. “Everyone in the crowd was excited when they realized what a special swim they had just seen when we announced the long-standing record had been broken,” Cindy Rowland, Pacific Swimming’s director, wrote in an email.

Clark won first place for all the swimming events he competed in at this year’s Far Western Championships. Pacific Swimming or PacSwim, a regional association that is part of USA Swimming, organizes the Far Western Long Course Championships. Cynthia Apuada, Clark's mother, said that her child seems to be “living by his name at this point”.

Asked about the champion swimmer’s unusual name, she said she’d always loved the name Clark. And her husband’s favorite superhero just happened to be Superman. So when their child was born, they decided to give him the name “Clark Kent”. The nickname “Superman” appeared naturally.

【推荐2】A short cooking video posted by a netizen on Tik Tok has recently become a popular hit on the site. Bearing the tag “Chinese food”, the video not only showed off the chef’s superb skills in making Chinese dishes, but it also got netizens abroad wanting to get a taste of China’s unique food culture.

Although the video was nothing master-level, just a rather standard homemade fried potato dish, it received more than 200,000 likes after only three days of posting. In addition to praising the chef, commenters wondered why such a simple Chinese dish could look like a fancy cuisine that had been made through tons of effort. “Even the most basic Chinese dish needs to have three elements: color, smell and taste. For example, color not only requires a chef to have sharp eyes, but also valuable experience,” said Wang, an experienced Chinese chef in Guangzhou.

Chinese cooking is not the only type of content covered by the tag. Other popular videos under the tag include “odd food” challenges, traditional Chinese dishes and Chinese snack tasting, the latter of which has become particularly popular among young omnivore vloggers (video bloggers) living in a world of continually expanding cultural globalization.

“I have been a fan of Chinese food ever since my Chinese friend cooked me di san xian at university. I was surprised by the dish’s taste and its look, which was very different from my home food, but felt it was very familiar to me because I noticed we share similar cooking skills,” said Bianca, an Italian Asian food fan.

“I started my channel by recording my roommate tasting my cooking. These videos got likes and comments gradually. Seeing some people commenting in German or English and saying ‘I want to try it’, I felt these videos can narrow the gap between the two cultures,” said Mr. Bean, a vlogger on Bilibili who promotes Chinese cooking.

【推荐3】If you live in San Diego, you’ve probably noticed some strangely coloured water on the beach lately. You might wonder about red tide, but it’s actually an intentional job. Scientists at UC San Diego Scripps Institution of Oceanography and University of Washington have been experimenting with dyeing (给……染色) the ocean at San Diego beach pink. What could they possibly be up to?

This is being done for a study that examines how fresh water on the outlet of the sea is intermixing with the ocean. The experiment is called Plumes in Nearshore Conditions (PiNC) . “I’m excited because this research hasn’t been done before and it’s a really unique experiment,” said Sarah Giddings, a Scripps coastal oceanographer leading the PiNC study. “The aim is to understand how fresh water interacts with ocean waves, since it is usually warmer than ocean water and more floating.” The researchers are hoping that this pink dye experiment will help them record more about how pollutants and sediments (沉积物) are distributed in the ocean water through these additions of fresh water.

The fresh water is dyed pink so that the team can easily keep track of it when fresh water is added to the sea water. The dye does not threaten the wildlife living there and is then spotted as it progresses in the water. It is tracked by sensors on poles that are located along the sand as well as by drones (无人驾驶飞机) . There’s also a device that tracks the light that is given off by the pink dye. The sensors record the height of the waves, ocean currents and temperature.

Giddings explained, “We’re bringing together a lot of different people with different expertise. I think it’s going to have some really great results and impacts. We will combine the results from this experiment with a former field study and computer models to help us further understand how the dyed fresh water spreads.”

【推荐1】Like most senior high school students in China, 17-year-old Liu Yu, from Yantai Development Zone Senior High School, Shandong, had planned to resume her studies earlier this year to prepare for the upcoming gaokao.

However, the Ministry of Education (MOE) announced in late January that the spring term for all schools would be put off due to the novel coronavirus pneumonia outbreak, forcing students like Liu to stay at home.

Rather than falling behind their original plan, Liu and many others have already begun studying full-time again – only from home – in what may have become the largest online teaching trial the country has ever seen.

To go with students’ new learning environment, a “cloud platform” was launched on Feb 17 to provide students in elementary and secondary schools with education resources covering all major school subjects, noted Lü Yugang, head of the ministry’s Department of Basic Education.“Students will be able to attend classes online or study via television,” he told China Daily.

For students in remote or rural areas with poor internet accessibility（获取）, a television channel by China Education Television started airing classes on Feb 17 so they can study at home, Xinhua News Agency reported.

But the online platform and TV channel don’t just offer school knowledge.Students can also learn about epidemic（流行病） prevention and control tips during the period, and receive education on patriotism, life and psychological health, according to a guideline issued by the MOE.

For some students, the chance to study from home has had some unexpected benefits.Yuan Siyi, who lives in Hubei province, used to get up before 6 am on school days, but since starting online courses, she gets more hours of sleep each morning.“I like online teaching because I have more freedom at home,” Yuan, who began her all-day courses on Feb 3, told TEENS.

However, online teaching and learning has its weaknesses compared to studying in a physical classroom.“My motivation to study is stronger when my classmates are around me and all working very hard,” Yuan said.According to the MOE, online courses are only temporary measures taken during the epidemic.“When the new term begins, schools will not replace classroom teaching with online classes,” Lü added.

【推荐2】Globally, people use roofs to dry out food, do their laundry and sleep. In Belfast, where we're based, there's a culture of enjoying looking down on the city from up high, because it's in a valley. But because we were a conflict area for a long time,many people didn't want to live, work or hang out in the city, and our roofs cape has been neglected.

Rooftop projects can be as big or as small as you want. They can be used as social or cultural spaces, for green or blue public facilities. But it's not just about commercial opportunities; it can be as simple as an individual turning his/her city balcony into a mini garden or vegetable patch. It's not just about doing it on a rooftop because it's “cool”.It's about giving up the deep-rooted thought that roofs are off limits and embracing their challenges as opportunities. That can make a huge difference. For instance, we're helping turn the rooftop car park of a city central shopping centre into an outdoor space for employees, due to restrictions they now face indoors because of COVID-19.

Using rooftops creatively allows us to cope with many of the challenges faced by cities today--be those environmental, social, technological, or cultural. At the moment,we're being forced to rethink how we use public spaces due to COVID-19. With lots of restrictions on enclosed areas, we should be acknowledging rooftops alternatives.For example,Rotterdam recently hosted a play that took place across its rooftops. Each roof lit up and hosted a different part of the drama, while residents sat and watched, listening to the action through headphones.

Are there any challenges? Rain is one. Also is health and safety. But there are creative and practical solutions to all the barriers we face. In fact,the challenges are what make rooftops so exciting----because they give you even more opportunities to be creative and solve problems. It is always a matter of trial and error.
