1 . Too much screen time for kids can lead to poor health the American Heart Association (AHA) says. A scientific statement published by the AHA in the medical journal Circulation said screen time from smartphones, tablet computers and other devices can lead kids to a sedentary(惯于久坐不动的) lifestyle ,increasing the possibility that they grow up as overweight or obese(肥胖的).
The AHA is the latest organization urging parents to limit how much time their kids spend in front of screens. It recommends children get one to two hours of screen time each day. Although television viewing among children and teens has dropped, the use of smartphones and tablet computers has surged.
“Although the mechanisms(机制) linking screen time to obesity are not entirely clear, there are real concerns that screens influence eating behaviors, mainly because children don’t notice when they are full when eating in front of a screen,” said Tracie Barnett, a researcher at the INRS-Institut Armand-Frappier Research Centre,in a statement.
Barnett, one of the authors of the statement, also urges parents to keep screens out of kids’bedrooms, raising the fear that too much screen time can affect sleep.
Many studies have warned about the potential (潜在的) negative effects of too much screen time. Last year, a study from researchers at San Diego State University(SDSU) found nearly half of teens who spent five or more hours in front of screens every day experienced long periods of hopelessness or sadness.
Apple, who makes the iOS mobile platform, plans to introduce new tools to devices to help users cut back on screen time. As for iOS 12,iPhones will include a screen time feature where users can control and review how they spend time on their mobile devices. Another company that makes the Android platform will introduce “digital well-being” tools such as screen time limits and a “wind down” option to encourage users to put down their phones before bed.

2 . You’ve heard that plastic is polluting the oceans — between 4.8 and 12.7 million tonnes enter ocean ecosystems every year. But does one plastic straw or cup really make a difference? Artist Benjamin Von Wong wants you to know that it does. He builds massive sculptures out of plastic garbage, forcing viewers to re-examine their relationship to single-use plastic products.
At the beginning of the year, the artist built a piece called “Strawpocalypse,” a pair of 10-foot-tall plastic waves, frozen mid-crash. Made of 168,000 plastic straws collected from several volunteer beach cleanups, the sculpture made its first appearance at the Estella Place shopping center in Ho Chi Minh City, Vietnam.
Just 9% of global plastic waste is recycled. Plastic straws are by no means the biggest source (来源) of plastic pollution, but they’ve recently come under fire because most people don’t need them to drink with and, because of their small size and weight, they cannot be recycled. Every straw that’s part of Von Wong’s artwork likely came from a drink that someone used for only a few minutes. Once the drink is gone, the straw will take centuries to disappear.
In a piece from 2018, Von Wong wanted to illustrate (说明) a specific statistic: Every 60 seconds, a truckload’s worth of plastic enters the ocean. For this work, titled “Truckload of Plastic,” Von Wong and a group of volunteers collected more than 10,000 pieces of plastic, which were then tied together to look like they’d been dumped (倾倒) from a truck all at once.
Von Wong hopes that his work will also help pressure big companies to reduce their plastic footprint.

3 . When almost everyone has a mobile phone, why are more than half of Australian homes still paying for a landline (座机)?
These days you’d be hard pressed to find anyone in Australia over the age of 15 who doesn’t own a mobile phone. In fact plenty of younger kids have one in their pocket. Practically everyone can make and receive calls anywhere, anytime.
Still, 55 percent of Australians have a landline phone at home and only just over a quarter (29%) rely only on their smartphones according to a survey (调查). Of those Australians who still have a landline, a third concede that it’s not really necessary and they’re keeping it as a security blanket — 19 percent say they never use it while a further 13 percent keep it in case of emergencies. I think my home falls into that category.
More than half of Australian homes are still choosing to stick with their home phone. Age is naturally a factor (因素)— only 58 percent of Generation Ys still use landlines now and then, compared to 84 percent of Baby Boomers who’ve perhaps had the same home number for 50 years. Age isn’t the only factor; I’d say it’s also to do with the makeup of your household.
Generation Xers with young families, like my wife and I, can still find it convenient to have a home phone rather than providing a mobile phone for every family member. That said, to be honest the only people who ever ring our home phone are our Baby Boomers parents, to the point where we play a game and guess who is calling before we pick up the phone (using Caller ID would take the fun out of it).
How attached are you to your landline? How long until they go the way of gas street lamps and morning milk deliveries?

| C．It may increase daily expenses. |
| D．It is as important as the gas light. |
4 . Twenty-five years ago, most young Britons wanted a career in law, to be a doctor, or, if they were creative enough, to take up singing. But today, things stand differently.
According to a survey by Tesco Mobile, a UK company, the “dream job” of young people aged between 16 and 25 in the UK is a video blogger, or “vlogger” (视频博主). The survey, carried out among 1,002 people, found that as much as 40 percent of them put vlogger as their number one choice on a list of ideal careers.
This change is undoubtedly as a result of the Internet and social media. They have made it so much easier to reach audience of the world, without having to enter a career in show business in the traditional way.
In the past, the biggest stars were trained by the Hollywood studios; now, anyone with a computer camera can become a star. Vloggers are the big stars of today because they are normal people interacting with their fans about everyday life.
However, what people see is only the bright side of being a vlogger and they fail to notice the fact that only those who are successful earn fame and fortune. For every success there are hundreds of others who never get off the starting line. There are the dreams that come true and the dreams that remain dreams forever.
Although being vloggers is popular, some young people choose to follow careers that don’t necessarily earn them fame, but allow them to make good use of the Internet to share their hobbies. Young Israeli David Leshaw, for example, runs a business called the Finishers Club. It’s an online platform for runners to keep a record of their races. His job allows him to express his enthusiasm, and is always a learning experience. And that's enough for him.

5 . The famous Spanish painter Pablo Picasso once said, “Every child is an artist. The problem he has is how to remain an artist once he grows up.”
This is both encouraging and discouraging. The fact that we were all born to be artists is certainly exciting, and yet the reality has proven that remaining one is a task that many of us have failed.
Fortunately, some people have seen the problem and want to solve it.
Western educators have suggested that we introduce the concept of “STEAM” instead of “STEM” - traditional “core majors” including science, technology, engineering, and math -since the “A”, which stands for “arts”, is just as important.
And on April 11, China’s Ministry of Education issued a guideline. Colleges and universities are required to provide more art-related courses and students need to earn a certain number of art credits in order to graduate.
These efforts came after many scientific studies had found that art education helps students develop self-confidence and teamwork skills, as well as habits of mind such as problem solving and critical thinking, according to The Washington Post.
It’s true that none of these skills target specific jobs. But as former US ballet dancer Damian
Woetzel told The Atlantic, the purpose of art is “to give kids the tools to become adults who are creative, adaptable, and expressive - capable of having their eyes and ears and senses alive”.And we can now see how we lost track of our born “artist self” on our way to growing up: We failed to keep our capabilities to see, hear and feel, and became blind, deaf and insensitive adults.
Hopefully, art education can help turn things around.

9 . Getting less sleep has become a bad habit for most American kids. According to a new survey(调查) by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school.
How much sleep you need depends a lot on your age. Babies need a lot of rest: most of them sleep about 18 hours a day! Adults need about eight hours. For most school-age children, ten hours is ideal(理想的). But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtime? Watch TV.
“More children are going to bed with TVs on, and there are more opportunities(机会) to stay awake, with more homework, the Internet and the phone,” says Dr. Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. Other experts say part of the problem is chemical. Changing levels of body chemicals called hormones not only make teenagers’ bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 pm.
Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. Three years ago, schools in Edina, Minnesota, changed the start time from 7:25 am to 8:30 am. Students, parents and teachers are pleased with the results.
