2 . Schools across the US East Coast canceled outdoor activities, commercial airline traffic was slowed and millions of Americans were urged to stay indoors on Wednesday as smoke from Canadian wildfires drifted south, blanketing cities in thick and yellow smoke.

“It’s critical that Americans experiencing dangerous air pollution, especially those with health conditions, listen to local authorities to protect themselves and their families,” US President Joe Biden said.

New York’s world-famous skyline, usually visible for miles, disappeared because of the smoke, which some residents said made them feel unwell.

“It makes breathing difficult,” Mohammed Abass said as he walked down Broadway in Manhattan. “I’ve been scheduled for a road test for driving, for my driving license today, and it was canceled.”

“It looks like Mars out there,” said Fox Forecast Center meteorologist Brian Mastro just before 2 p.m.

New York Goveror Kathy Hochul called the situation an “emergency crisis,” noting that the air pollution index for parts of her state were eight times above normal.

In Bethesda, Maryland, a high school moved its graduation ceremony indoors, while a Brooklyn, New York, elementary school deferred its “Spring Fling” dance party. A school in Montelair, New Jersey, called off a fifth-grade trip to an amusement park.

The smoke was wafting (飘荡) over the US northern border from Canada, where hundreds of forest fires have burnt 9. 4 million acres and forced 120,000 people from their homes in an unusually early and intense start to Canada’s wildfire season.

Tyrone Sylvester, 66, playing chess outside in Manhattan’s Union Square us he has on most days for 30 years, but wearing a mask, said he had never seen the city’s air quality so bad. “When the sun looks like that,” he said, pointing at the smoky sky, “we know something’s wrong. This is what global warming looks like.”

Poor air quality is likely to continue into the weekend, with a developing storm system expected to shift the smoke westward across the Great Lakes and deeper south through the Ohio Valley and into the mid-Atlantic region, AccuWeather said.

3 . Rivera, 27, was jogging on a path next to Claiborne Parkway in Ashburn near the Dulles Greenway about 6 p.m. A 71-year-old woman from South Riding Was driving a Toyota SUV on the road. And a deer came from somewhere.

The SUV struck the deer, which sent the animal flying into Rivera, who remembers running one minute and then coming into an ambulance as a doctor told her she needed to cut away one of her favorite running shirts “because it had deer blood all over.” “That’s when I knew a deer was part of this,” Rivera said Saturday.

The deer died on the spot. The driver was treated at Inova Loudoun Hospital and recovered. Rivera, who was taken to the same hospital and recovered on Thursday evening.

Barely 5 feet tall, Rivera already had been jokingly nicknamed “The Hulk” by her friends, which means a giant person. “So, I guess now they can really call me that,” she said.

She had finished five miles Thursday in her orange running shoes and was on the final stretch toward her home in Ashburn when she was hit by the deer.

“I’d thought that the run would make me feel better after work,” said Rivera, an administrative analyst. She has been a runner for about five years and started taking part in marathons last year. She also leads runs for a Loudoun fitness club.

A female passer-by called 911 and used Rivera’s phone to dial numbers that reached Rivera’s boyfriend and her family. “I want to really thank her, whoever she was. And I am glad the driver is all right.”

Rivera said she runs on the path often and wilt again. So how will she retell this tale? It’s hard to know where to start. Maybe I was out for a run one day. No, actually I probably have to start with, this really strange thing happened to me once.”

4 . On June 23,2018,twelve young Thai boys and their assistant football coach wandered into a karst cave in northern Thailand, near the border with Myanmar. What happened next would grab the world’s attention and lead to a complex and daring international rescue operation. The 10.3-kilometer-long Tham Luang cave flooded, trapping the boys in total blackness nearly 2.5 kilometers from the cave entrance.

Thousands of people from around the globe participated in the rescue effort, including military personnel, medical experts and the rock stars of the operation — cave divers. The divers, who safely removed all of the Thai children and their coach after 18 days underground, dealt with tight spaces and low visibility in muddy water- conditions that would prove deadly: Saman Gunan, a former Thai Navy Seal, died while transporting air tanks into the cave.

While the sport of cave diving had received attention in the pop culture area prior to the rescue mission in North Thailand, there is little doubt that the brave divers at Tham Luang cave helped push the activity and its varieties of risks into global society’s minds.

The sport-often referred to as among the world’s most dangerous recreational activities-has its roots in pre-WWII England. Since then, the recreational practice of cave diving, described by Australian cave explorer Richard Harris (a participant in the Tham Luang cave rescue) as an “unusual hobby” for “the ordinary,” has spread around the world-China included.

Over 1,000 kilometers northeast of Tham Luang cave, in South China’s Guangxi Zhuang Autonomous Region, lies karst-peak-covered Du’an county-China’s little-known cave diving Mecca.

Home to thousands of kilometers of underground rivers, Du’an county offers divers spellbinding geological formations, perhaps the world’s largest collection of blind fish species and a rare variety of freshwater jellyfish.

5 . National Drowning Prevention Week

National Drowning Prevention Week is July 17-23, 2022, which promotes the awareness of the drowning prevention problem in Canada and the need for individuals, communities, organizations, and government to take action in an effort to save lives. Drowning is preventable!

Measures to Promote

Members of the public, community groups, and government are encouraged to promote the following measures that have been taken from the World Health Organization’s publication Preventing Drowning.

★Teach basic swimming and water safety skills to school-age children aged 6 years and older. Activity Suggestions:

• Offer Swim To Survive sessions to your community during National Drowning Prevention Week

• Promote people to learn to swim by registering in Swim For Life lessons

• Work with local schools to book swimming lessons in the upcoming year

★Provide community-based childcare for preschool children to reduce the drowning risk.

•Work with local officials to create childcare options that are less than 20 minutes away for all communities

★Train bystanders in safe rescue and CPR (心肺复苏). Activity Suggestions:

•Offer free CPR training opportunities to the public during National Drowning Prevention Week

•Promote learning to rescue others by registering in Bronze Medallion

National Drowning Prevention Week Announcements

Since the United Nations (UN) passed a resolution declaring July 25 of each year as World Drowning Prevention Day last year, we have stopped our request for community announcements for National Drowning Prevention Week. This does not lessen the importance of raising awareness during National Drowning Prevention Week, but allows us to focus more on the other important matters.

6 . In 1840, Chicago was a small town of forty-five hundred souls. It ranked 92nd in population in the United States. Yet, only three decades later, by 1870 — just a year before the great fire — Chicago was closing in on a population of 300,000, making it the fifth-biggest city in America and the fastest-growing city in the world.

What led to all this rapid growth? In three words: location, location, location.

“Chicago was near the center of the country, and near where the waterways and railways met,” city historian Tim Samuelson notes. “It was a perfect place for anything and anyone to get anywhere...”

Timing had a lot to do with it, too. America was moving from a rural to an industrial power. Chicago was right in the middle of the action. Ironically, its rapid growth was almost its undoing. “Chicago had to build, and build quickly, and so they built it out of wood,” explained Sarah Marcus of the Chicago History Museum. “It was quick, it was easy, and it was cheap.”

And, as it turned out, very “easy” to catch fire.

By most accounts, the fire started on the city’s West Side, near the De Koven Street barn of Patrick and Catherine O’Leary. No one is sure of the cause, but it could have been anything, from vandals (故意) to a drunken neighbor to that clumsy cow of urban legend.

Within minutes, the fire got out of control, tearing through Chicago’s business district. The fire was so hot, it created its own tornado of flame. By 3:30 a.m., all hope of saving large parts of the city was gone. Nearly 30 hours later, the fire finally died. The reason? There was nothing left to burn.

The losses were shocking: The fire took away nearly 300 lives, destroyed over 17,000 buildings covering almost 3.5 square miles, and caused damage of over $200 million—about 3.8 billion today. Roughly a third of the city lay in ruins, and one out every three people living in Chicago — nearly 100,000 residents — became homeless overnight.

8 . Barbara was driving her six-year-old son, Ben, to his piano lesson. They were late, and Barbara was beginning to think she should have called it off. Barbara, a nurse at the local hospital, was very tired at that moment. The coldest season and the terrible weather just brought them more difficulties.

“Mum!” Ben cried suddenly. “Look!” Just ahead, a car had lost control on the icy road and crashed（猛撞）into a telephone pole. Barbara stopped her car quickly and opened the door. She said to Ben, “Dear, promise me you'll stay in the car!” “I will, Mum,” Ben said as his mum ran. She was a nurse-she might be able to help the unlucky people. It was terrible. Two girls aged about 18 were in the car. One was dead and the other was still breathing. Barbara quickly cleaned the wounds in the driver's head. Ben called for help on his mum's phone. Soon an ambulance came. “Good job, Barbara, you've saved her life,” one doctor said as he examined the driver's wounds. Barbara walked back to her car with a feeling of sadness, especially for the family of the girl who had died. Later, Barbara was able to meet the family of the driver. They expressed their thanks to Barbara for the help she had provided.

10 . Norwood, a junior High School student, was driving three friends home in St. Petersburg, when another driver crashed into her from her left and made her car hit the tree. The impact jammed shut the driver’s side door, so Norwood climbed out the front window. Two of her friends managed to get out of the car unharmed, but her 16-year-old friend Zarria didn’t. She run back to the car only to find Zarria was just sitting there reactionless.

A lot of people started to gather around to see what was happening. Norwood started yelling, “Back up, back up, she needs space.” Norwood pulled Zarria out of the back seat, avoiding broken glass from the window. “That’s when I checked her pulse on her neck. I put my head against her chest, and I didn’t really hear nothing. So that’s when I just started doing CPR on her.” Norwood told the reporter. After the 30 compressions and two rescue breaths, Zarria regained consciousness. Ambulance quickly arrived and rushed her to the hospital to receive medical help.

When Miller, Norwood’s high school teacher, learned that Norwood saved a friend just   one day after completing CPR training, she was at a loss of words and so proud. Norwood participates in the school’s Athletic Lifestyle Management Academy (ALMA). The program prepares students for various careers in health science. “We do vital signs and they learn how to take blood pressure and check pulse.” Miller introduced. And another one of the skills learned is CPR. “There are two components, a hands-on skills component where they have to demonstrate that they’re able to do CPR well, and then there’s a written test component, showing that they remember that knowledge.”

Thanks to Norwood’s quick thinking, Zarria is recovering well. She also isn’t surprised by her friend’s actions. “She will always help any way she can, so I wasn’t really shocked about that.”
