Unit 5 First Aid 知识点题库

Do you live in a city? You've probably noticed how noisy and crowded life in a city can be. What if you could live next to a calm lake instead?

As it turns out, living near bodies of water—lakes, rivers, ponds, even oceans—can help us feel both happier and healthier. Those who live less than a kilometer from the coast are around 22 percent less likely to have mental health problems than those who live 50 kilometers or more away, according to a study by researchers from the University of Exeter, the UK. People who visit the coast at least twice a week tend to experience better general and mental health as well.

So how does "blue space" make us feel better? For one thing, aquatic environments tend to have less pollution and more sunlight, both of which are linked to better mental and physical health. People who get more sun tend to be happier than those who do not.

There's also air above the sea. After spending time near the ocean, you might find that you feel more relaxed than usual. This is because sea air is filled with negative ions(负离子). These ions balance our levels of serotonin(血清素), a chemical that affects our moods. With balanced serotonin levels, we feel more calm and relaxed, according to the Daily Mail.

Finally, people who live near water tend to be more physically active, according to The Guardian. Water sports like swimming and rowing can help us stay in shape, which in turn keeps us healthy.

Sonia learnt some first aid skills in her Infant CPR (婴幼儿心肺复苏) class. Last week she told us that she 1 her daughter's life using the skills. Her experience might be 2 to other parents with young children. Here is her 3 ：

I jumped out of the car, 9 her out of the car seat, flipped her over,  and hit her on the 10 three times. I saw something fly out of her 11 . I saw it was the Band­Aid when I picked it up.I was so 12 . I couldn't imagine what could have happened if we had driven home instead of parking the car there.

I went home and immediately signed up for Child CPR. I had taken Infant CPR in our town and  remembered not to stick my 13 in her mouth to  get out  the  choking  object (堵塞物)— 14 my instinct (直觉) was to do just that.

It terrifies me that something like this can happen so suddenly to people around us. I've been telling all my friends with children to sign up for CPR classes because you just 15 know what might happen.,

Seven years ago, Kevin Stephan, was a bat boy for his younger brother's Little League baseball team. A player who was 1 up accidentally hit him in the chest with a bat. Kevin's heart 2 beating.

“All I remember is that I dropped the bat off, and all of a sudden just got hit in the chest with something, and I turned around and passed out, ” Stephan said. 3, a nurse whose son played on that 4 was able to revive(使苏醒)him and save his life. Stephan's mother said he was very fortunate. Penny Brown, the nurse, was 5 to be at work that night, but was given the day off at the last 6.

Now comes the really interesting part. Last week that same nurse was eating at the Hillview Restaurant 7 she began to choke on her food. Witnesses say people were 8 for someone to help her. “The food wasn't going anywhere and I totally couldn't breathe, ” Penny said. “It was very frightening. ”

Restaurant employees yelled for Stephan to come out and 9. “They knew I was a volunteer firefighter and they 10 me over and I did the Heimlich, and I guess you 11 say I saved Mrs Brown, ” Stephan said. At the restaurant, they 12 what had happened before. Seven years ago, Brown had 13 Stephan's life. Now at age 17, he had returned the 14.

On Saturday, the two met again at the Bowmansville, N. Y. , Fire Hall where Stephan is a junior firefighter. He 15 her with a bouquet of flowers, and his parents were also there to greet Mrs Brown.

The physical benefits of exercise can three factors.

Imagine this: You're bleeding. Nothing seems to make it stop. Then you apply a gel to your wound, and the blood stops coming out within seconds. You're healed in minutes. This is the VetiGel, created by Joe Landolina—a 22-year-old who invented the product many years ago.

Landolina is now the founder and CEO of Suneris, a company that produces the gel. Suneris announced last week that it would begin to ship VetiGel to vets later this summer. Humans won't be far behind.

When injected into a wound site, the gel can form a clot (凝块) within 12 seconds and heal the wound within minutes. Once it hits the damaged tissue, whether it's open skin or a soft organ — livers, kidneys— the gel instantly forms a structure. "What that means is that the gel will make a structure that holds the wound together, "Landolina says.

As fast-acting as VetiGel is, its inventor may be faster. Landolina invented an early version of the gel out of his grandfather's lab. He was still in high school. Over the next four and a half years, Landolina turned the prototype into a business. The first product costs $150. Landolina says Suneris has its sights set on US first, followed by a release in Europe and Asia sometime early next year.

A few years down the line, Landolina says, the goal will be to expand out of vet offices to help treat members of our own species. He forecasts receiving FDA approval within the year for testing on human wounds. If all goes according to plan, VetiGel will first help military personnel and EMTs treat injuries. Then it will enter operating rooms and, finally, individual homes.

Landolina says Suneris has yet to observe any negative side effects of VetiGel. The company holds weekly meetings with vets to ensure the product meets their needs.

A wealthy man and his son liked to collect rare works of art. They had everything in their collection, from Picasso to Raphael. They would often sit together and admire these great works of art.

When the Vietnam conflict broke out, the son went to war. Unfortunately he died in battle while rescuing another soldier. The father was in deep sorrow for his only son.

About a month later, just before Christmas, there was a knock at the door. A young man stood at the door with a large package in his hands. He said, "Sir, you don't know me;I am the soldier for whom your son gave his life. He saved many lives that day, and he was carrying me to safety when a bullet struck him in the heart and killed him instantly. He often talked about you, and your love of art. "The young man held out this package. "I know this isn't much. I'm not a great artist, but I think your son would have wanted you to have this. "

The father opened the package. It was a picture of his son, painted by the young man. He stared in surprise at the way the soldier captured the personality of his son in the painting. The father was so drawn to the eyes that his own eyes welled with tears. He thanked the young man and offered to pay for the painting. "Oh, no sir, I could never repay what your son did for me. It's a gift. "

The father hung the picture on the hall. Every time visitors came to his home, he took them to see the portrait of his son before he showed them any of the other great works he had collected.

The man died a few months later. There was to be a great auction(拍卖)of his art collection. Many influential people gathered, excited over seeing the great paintings and having the opportunity to purchase one for their collection.
