1 . It’s no secret that sleep is important to your overall health, but a lack of sleep could have great effects on your heart, a new study shows. The researchers said people with insomnia(失眠症)are more likely to have a heart attack.
Insomnia is the most common sleep disorder in the US, the researchers wrote in their report, noting that 10% to 15% of people in the US struggle with it. The meta-analysis of previously published research suggests that the potential association between insomnia and heart attack risk is strongest in women.
Dr. Martha Gulati, director of prevention at the Cedars-Sinai Smidt Heart Institute, said that most of her patients are women and that insomnia is a noted risk factor for women who have had any form of ischemic heart disease. “We see it probably in 1 in 10 patients in the United States,” said Gulati, who was not involved in the new research. “It is my impression that almost everyone experiences insomnia at some point in their life. The estimate is that 1 in 2 adults experience it at some point in their life, maybe in the short term because of stressful moments.”
For their analysis, the researchers defined insomnia as a sleep disorder with three main symptoms(症状): Difficulty falling asleep, difficulty staying asleep and waking early and being unable to fall back asleep.
The study also found an association between increased heart attack risk and how long a participant slept each night. Those who slept five hours or less had the highest association with heart attack risk and were 1.56 times more likely to have a heart attack than people who slept seven or eight hours. Longer sleep duration wasn’t always more protective. The study found that people who slept six hours a night had a lower risk of a heart attack than those who slept nine hours or more. “A lot of studies have pointed somewhere between seven and eight hours of sleep being the magic number for us,” another researcher said. “There is obviously variability for everyone, but too much sleep is rarely the issue.”

2 . The summer vacation is drawing near. Here we have prepared a visual feast for our boys and girls. Let’s feast our eyes first.
Jurassic World Dominion
It is the final film in the second trilogy of dino-movies, and it’s the first one which really deserves to be called “Jurassic World” rather than “Jurassic Park”. Yes, prehistoric dinosaurs are out and about in the wild this time, rather than being stuck in a theme park.
Director: Colin Trevorrow
Official Competition
Cruz and Banderas have been two of Spanish cinema’s famous superstars for decades, and yet have only rarely acted on the screen together. Now, once again, that wrong has been righted by Official Competition. Cruz is an art-house director who is adapting a Nobel-Prize-winning novel in the film. Banderas plays a dull Hollywood action hero who is hired to star in it.
Director: Mariano Cohn & Gaston Duprat
Brian and Charles
Not a typical science-fiction movie, Brian and Charles is a low-budget, low-key British comedy starring and co-written by David Earl, a regular in Ricky Gervais’s sitcoms. “Brian and Charles is this year’s sweetest film by a country mile,” says Cory. “It’s like Edgar Wright’s The Mighty Boosh project thrown into a cotton-candy machine, and it is also one of the most surprising films about being a parent, even when your son is a 7-feet-tall robot who loves cabbages.”
Director: Jim Archer
Lightyear
After four Toy Story films, everyone’s favourite space ranger action figure, Buzz Lightyear, gets to leave Woody and friends behind, and go off on an adventure on his own. Or so you might assume so. In fact, the latest Pixar cartoon isn’t about the toy.
Director: Angus MacLane

3 . Frank and his brother Jack lived near the ocean. Frank was outgoing while Jack was shy. They liked doing different things. Frank was famous for organizing games of beach volleyball, football, and any other sport imaginable. Jack preferred to draw, paint, or build sandcastles (沙堡).
Frank didn’t understand why Jack would rather do artistic things than play ball. He believed sports often allowed many kids to play together. That was when Jack’s idea hatched. He would show Frank what doing things together looked like!
After Jack finished creating a special sandcastle with stairs, towers and walls, he took pictures of it. Then he painted colorful posters featuring (突出) his sandcastle and the question, “Can you top this?” He hung his posters everywhere in town, announcing his plan for a day of sandcastle artistry-all ages welcome.
When Frank saw poster, he not so nicely told Jack that no one would come. Still, shortly after sunrise on Saturday, Jack was on the beach digging in the sand. By mid-morning, four kids were sculpting (雕塑) the sand alongside him. By noon the number had increased a lot.
After Frank came back from his ball game, he went to check how his brother’s plan turned out. He couldn’t believe what he saw. At least 30 people were building a city of sandcastles, and everyone was chatting and laughing and working together! It was the most beautiful thing he had seen on the beach.
“I guess you’ve proved me wrong,” Frank said. “You should make this sandcastle day a yearly tradition!” Handing Frank a shovel (铲子) with smile, Jack got started together with his brother on their super creation in the sand.

4 . On the afternoon of March 23, 2022, Chinese astronauts on board China’s Tiangong space station gave a science lesson 400 kilometers above Earth. It was a great success. Do you still remember the first space lesson hosted by Wang Yaping in 2013? Helped by the other two astronauts, she gave the lesson to more than 60 million school children all over the country.
While watching the science lesson from the Tiangong-1 on the morning of June 20, 2013, Wang Lutian, a 10-year-old disabled student at a special school in downtown Beijing, was drawing a colorful rocket with crayons in his classroom. “Moon…stars…a rocket to the sky,” Wang explained his work in a cheerful voice. At that time, he and more than 100 other disabled students were enjoying the lesson given by Wang Yaping, who talked about movements in micro-gravity (微重力) environments. “Zero gravity!”Qian Shaohong, another student at the school, shouted when he saw astronaut Nie Haisheng making a show of crossing his legs in mid-air. “Scientific knowledge has helped open a window for the children to know about the world,” said Zhang Yini, a teacher at the school.
The lesson also increased interest in space science among teenagers living on the “roof (屋脊) of the world”. “I was most interested in the presentation of the ‘water ball’ in a gravity-free environment. It’s really amazing,” said Rigzin Jigme Doje, a high school student in Lhasa, Tibet. Describing himself as a lover of physics, Doje said the lesson helped him stay true to his dream of becoming a physicist.
The lesson also encouraged other Tibetan school children to relate the mysterious world of outer space to their hometown.

5 . Success is often considered to be the opposite of failure. To teenagers, it is the achievement of a goal or completion of something they really need, such as good grades and the ability to get along well with their classmates. Some schools used to agree with most parents who measured (判定) the success of their children according to grades, but now they pay special attention to moral (道德的) education and character-building to make sure teenagers achieve success in building human relationships.
Schools give chances to students to discover their hidden ability so that they can enjoy some form of success. For example, those good at speaking skills are advised to take part in speech competitions while those interested in arts are expected to perform in front of their classmates. Teenagers also get the pleasure of success when they join their favorite clubs.
Teenagers are often told that success is not easy to achieve and that success lies in hard work. Great efforts have to be put into project work. Doing things much later than planned should be avoided as this will lead to a mountain of work which finally makes them nervous. Another good quality (品质) is a sense of responsibility which makes them remember that a task has to be completed.
Sticking to moral values is the key to success too. Honest teenagers will win the trust of friends leading to good relationships. Self-motivation (自我激励) is another quality to be developed, for self-motivated teenagers will have the strong will and drive to perform a task and finally get to enjoy a sense of achievement.

9 . Tu Youyou has become the first Chinese woman to win a Nobel Prize for her work in helping to discover a crucial new treatment for malaria. The 84-year-old’s route to the honour has been anything but traditional. In China, she is being called the “three nos” winner: no medical degree, no doctorate, and she’s never worked overseas.
In 1967, malaria, a deadly disease at that time, spread by mosquitoes was decimating Chinese soldiers fighting Americans in the jungles of northern Vietnam. A secret research unit “Mission 523” was formed to find a cure for the illness. Two years later Tu Youyou was instructed to become the new head of “Mission 523”.
The team read ancient books carefully for a long time to find historical methods of fighting malaria. When she started her search for the medicine for malaria, more than 240,000 compounds around the world had already been tested, without any success. Finally, the team found a brief reference to one substance, sweet wormwood, which had been used to treat malaria in China around 400 CE. The team took out one active compound in wormwood, and then tested it.
But nothing was effective until Tu Youyou returned to the original ancient text. After another careful reading, she changed the drug recipe one final time, heating the compound without allowing it to reach boiling point.
After the drug showed promising results in mice and monkeys, Tu Youyou volunteered to be the first human recipient of the new drug. In any case, Tu Youyou is consistently praised for her drive and passion. One former colleague, Li Lianda, says Ms Tu is “unsociable and quite straightforward”, adding that “if she disagrees with something, she will say it.”
Another colleague, Liao Fuming, who has worked with Tu Youyou for more than 40 years, describes her as a “tough and stubborn woman”. Stubborn enough to spend decades piecing together ancient texts, she applies them to modern scientific practices. The result has saved millions of lives.

10 . If you really want to go green, here’s good news:eating green is good for you. The very foods with a high carbon (碳) cost — meat, pork, dairy products, processed snacks — also tend to be filled with fat and calories. A green diet would be mostly vegetables and fruit, whole grains (全谷物), fish and lean meats (瘦肉) like chicken — a diet that is good for environment and your figure. Eating green can be healthier and beneficial to the climate.
It may be hard to believe that a meal in a fast-food restaurant produces more carbon than your trip to a faraway place. More than 37% of the world’s land is used for agriculture, much of which was once forested. Deforestation (砍伐森林) is a major source of carbon. The fertilizer (化肥) and machinery needed on a modern farm also have a large carbon footprint, as does the network of ships and trucks that brings the food from the farm to your plate.
The most efficient way to reduce the carbon footprint of your menu is to eat less meat, especially beef. Raising cattle takes a lot more energy than growing the equivalent (相等的) amount of grains, fruit or vegetables. What’s more, the majority of cattle in the US are fed on grain and loads of it — 670 million tons in 2002 — and the fertiliser used to feed that creates separate environmental problems.
Focus on eating lower on the food chain, with more plants and fruits and less meat and dairy. It’s simple. We can change today what goes into our bodies for the health of our planet and ourselves.
