1 . The sound that woke Damian Languell at 8:15 am was so loud that he assumed it came from inside his house. As he got up to investigate, he heard another sound, this one coming most definitely from outside. Looking out of his bedroom window, he spied a tree engulfed (淹没) in smoke about 500 yards away. A car was wrapped around the tree’s base, its engine on fire.

Grabbing buckets of water, Languell and his girlfriend ran to the crash site. The wreck looked worse up close. The car, a 1998 Buick, was split nearly in two, and the tree was where the driver’s seat ought to have been, as if planted there. No one should have survived this crash, and yet there was 16-year-old Quintin Thompson, his terrified face pressed against the driver’s side window, in visible pain. Languell tried putting out the fire with his buckets of water with no success. When the flames got into the front seats, he realized he had to get the boy out of there.

In an act that a police report described as showing “complete disregard for his own safety”, Languell opened the Buick’s back door and crawled in. Thompson was struggling to get free, Languell says. “That’s when I noticed how bad his legs were.” Using a pocketknife he’d had the foresight to bring with him, he sawed through Thompson’s seat belt.

Now that Thompson was free, Languell pulled him out a back window of the vehicle, then dragged the teen to safety before the entire car was engulfed in flames.

Although Thompson suffered multiple fractures (骨折) to his legs, spine, and face, a social media post described him as “looking great, smiling, and joking.” Languell thinks about that day often. “My heart goes out to Thompson. When you are that close to that level of hurt, you feel it so directly.”

3 . Population data for European mountain birds have been for the first time combined in a recent study, with worrying results: the abundances of mountain-specialist birds has declined by as much as 10% in the 2000s.

Ecological communities in mountain areas include species not found in any other habitats. These species are also very susceptible to climate change, as global warming is reducing their liveable habitats. In principle, species may relocate further up the mountains, but closer to the top their habitat inevitably shrinks.

According to the new article, the abundance of European mountain birds has in fact declined in line with climate change projections.

The recently released study examined the population trends of 44 bird species in the 2000s in the mountain and fell regions of Fennoscandia, Great Britain, the Alps and the Iberian Peninsula. A decline was seen in 14 of the observed species, while eight of them saw significant increase.

“On average, population decline among the species studied was 7% over the 13-year research period, making the situation of mountain birds distinctly worse compared to, for example, European forest birds, whose numbers did not change during the same period,” explains Aleksi Lehikoinen, an Academy of Finland research fellow at the Finnish Museum of Natural History Luomus (part of the University of Helsinki), who headed the study.

The situation is the direst for species that only inhabit mountain regions and are unable to live in other European environments. For these species, known as mountain specialists, the numbers dwindled by as much as 10% during the monitoring period.

6 . When I was a baby, I entertained you and made you laugh．Whenever I was “bad”, you’d shake your finger at me and ask: “How could you?”—— but then you’d give up, and roll me over for a belly scratch and I believed that life could not be any more perfect．

My housetraining was a long process, because you were terribly busy, but we worked on that together. We went for long walks, runs in the park and car rides. We stopped for ice cream. I took long naps in the sun waiting for you to come home at the end of the day.

Gradually, you began spending more time at work and on your career, and more time searching for a human mate. Eventually, you fell in love. She, now your wife, is not a dog person, but I still welcomed her into our home. I was happy because you were happy. Then the human babies came along and I shared your excitement, I was fascinated by their pinkness, how they smelled, and I wanted to mother them too. Your wife was afraid I would bite them. But nevertheless, as they began to grow, I became their friend.

Now, you have a new job in another city and you and they will be moving to an apartment that does not allow pets. You’ve made the right decision for your “family”, but there was a time when I was your only family.

I was excited about the car ride until we arrived at the dog pound. It smelled of dogs and cats, of fear, of hopelessness. You filled out the paperwork and said: “I know you will find a good home for her.” They shrugged and gave you a pained look. The children were in tears as they waved me goodbye. And “How could you?” were the only three words that swept over my mind.

Is it better to live with hope or without hope? At first, whenever anyone passed my pen, I rushed to the front, hoping it was you, that you had changed your mind and that this was all a bad dream.

My beloved master, I will think of you and wait for you forever. I hope you receive more faithfulness from your family than you showed to me.

7 . A teenager needs to have a sense of independence in their life to feel secure (安全的). To some teenagers independence means a lot to them, and I think that some parents don’t allow their teenagers enough independence.

Independence has something to do with freedom. Some kids are not allowed to go anywhere alone, and the only thing their schedule includes is going to school, coming home, going to sleep, and repeating the process the next day. Parents tend to be afraid that their kids can get hurt if they go outside into the world. But if parents control their kids too much, they may never learn to live on their own. The best way for a teenager to learn lesson is through experience. I think it is beneficial for teenagers to have freedom.

Teenagers’ lack of freedom can also stop them from having good friendship at school. Some might say this is a good thing, because it helps them focus more on their school work. I argue that this can only discourage them not to do their school work. Some parents do not allow their children to be around their friends outside the school, thinking that this will get them into trouble. But I don’t think so. Instead, isn’t this a good reason for parents to get their children a cellphone? Cellphones allow teenagers to stay in touch with their parents, and communicate with friends.

Privacy is another issue between parents and their teenagers. Teenagers tend to enjoy relaxation by themselves in their own room. This also gives them a sense of independence. It often annoys teenagers when their parents enter their room when they are not home. I know that my mom always goes in my room when I’m not home, and this has brought me to the point where I have asked many times to get a lock on my door.

8 . Two weeks ago, a 5-year-old girl named Sunshine Oelfke emptied out her piggy bank (存钱罐) onto the living room floor and immediately started counting. Her grandmother, Jackie Oelfke, thought she was playing as she carefully lined up the coins, but then she saw the girl put the coins into a plastic bag and place it in her backpack.

“What are you doing with that money?” Jackie asked her granddaughter.

“I’m taking it to school,” Sunshine replied. “I’m going to take it for milk money. My friend Layla doesn’t get milk— her mom doesn’t have milk money and I do.”

Jackie’s heart melted at Sunshine’s words. Choked with strong feelings, Jackie held her sweet granddaughter tightly in her arms.

Last week, Jackie and Sunshine met with her teacher, Rita Hausher, and handed her the $30 the kindergartner had saved. There are 20 kids in Sunshine’s class and about half don’t get milk. It costs $ 0.45 a carton (纸盒). The total adds up to about $180 a month for every child in the class to have milk every day.

After dropping Sunshine off at school, Jackie posted a tearful video on Facebook to explain her granddaughter’s plan. To her surprise, many people offered to donate toward the cause. Within a week, Jackie raised more than $1,000. Now every student in Sunshine’s class can get free milk for the rest of the year.

Jackie said Sunshine doesn’t see her kind act as a big deal. She was just trying to look out for her friends. “She doesn’t understand the effect she’s brought about,” Jackie said. “But now she knows she can do whatever she puts her mind to.”

9 . There is nothing more important than the safety of our children. Did you know that unintentional injury(意外伤害) is the main cause of death in children under 14 years old and with a third of them happening in the home? One of the top reasons a child under the age of three will visit an emergency room is because of household injuries and sadly, 70% of children who die from unintentional injuries are under the age of four. Every room in the home will have its own set of child safety problems. Two of the main danger zones are the kitchen and the bathroom.

Before I became a young mother, I crawled(爬) around the house on my hands and knees to see things from a child’s perspective(视角). You would be amazed at what you can discover by doing something so simple. We didn’t have toilet covers. A child is top heavy because their heads are bigger than their bodies and can easily fall into the toilet.

You might be surprised with the number of children falling out of windows every year, especially during the summer months. Something as simple as a child leaning against a window screen can result in a serious injury. The best way to prevent this type of injury is by setting up a child safety window guard.

As parents, we do the best we can by providing as much protection as possible to make sure of the safety of children. And as there are so many products(产品) out there to help us do this, there is nothing like good old-fashioned supervision(监护). So, use common sense and products that help to keep your child safe, and you will have provided a safe environment for your children.

10 . John von Neumann was the oldest of 3 children of a banker, and his speed of learning new ideas and loving problems stood out early. At 17, his father tried to persuade him not to become a mathematician because he might lead a poor life being a mathematician, so von Neumann agreed to study chemistry as well. In 1926, at 23, he received a degree in chemical engineering and a Ph. D. in mathematics. From then on, mathematics provided well enough for him, and he never had to turn to chemistry.

In 1930, von Neumann visited Princeton University for a year and then became a professor there. His first book was published in 1932. In 1933, the Institute for Advanced Study was formed, and he became one of the 6 full-time people in the School of Mathematics (Einstein was one of the others).

World War Ⅱ hugely changed von Neumann’s areas of interest. Until 1940 he had been a great pure mathematician. During and after the war, he became one of the best mathematicians who put mathematical theories into practice. During the last part of the war, he became interested in computing machines and made several fundamental contributions. After the war, von Neumann continued his work with computers, and was generally very active in government service. He received many awards, was president of the American Mathematical Society and was a member of the Atomic Energy Commission. He died of cancer in 1957.

Von Neumann made several great contributions and any one of them would have been enough to earn him a firm place in history. He will be remembered as one of the greatest minds of the 20^th century.

Von Neumann really was a legend in his own time, and there are a number of stories about him. His driving abilities is a part of his legend. He reported one accident this way: “I was driving down the road. The trees on the right were passing me in an orderly fashion at 60 miles per hour. Suddenly one of them stepped in my path.”
