1 . A schoolgirl saved her father’s life by kicking him in the chest after he suffered a serious allergic (过敏的) reaction which stopped his heart.Izzy, nine, restarted father Colm’s heart by stamping (踩) on his chest after he fell down at home and stopped breathing.Izzy’s mother, Debbie, immediately called 999 but Izzy knew doctors would never arrive in time to save her father, so decided to use CPR.However, she quickly discovered her arms weren’t strong enough, so she stamped on her father’s chest instead.Debbie then took over with some more conventional chest compressions (按压) until the ambulance arrived.Izzy, who has been given a bravery award by her school, said, “I just kicked him really hard. My mum taught me CPR but I knew I wasn’t strong enough to use hands. I was quite scared. The doctor said I might as well be a doctor or a nurse. My mum said that Dad was going to hospital with a big footprint on his chest.”“She’s a little star，” said Debbie, “I was really upset but Izzy just took over. I just can’t believe what she did. I really think all children should be taught first aid. Izzy did CPR then the doctor turned up. Colm had to have more treatment on the way to the hospital and we’ve got to see an expert.”Truck driver Colm, 35, suffered a mystery allergic reaction on Saturday and was taken to hospital, but was sent home only for it to happen again the next day. The second attack was so serious that his airway swelled, preventing him from breathing, his blood pressure dropped suddenly, and his heart stopped for a moment.He has now made a full recovery from his suffering.

2 . Scientists say they have developed a system that uses machine learning to predict when and where lightning will strike. The research was led by engineers from the Swiss Federal Institute of Technology in Lausanne, Switzerland.
Lightning is a strong burst of electricity in the atmosphere. It can strike between clouds or between a cloud and the ground. Since lightning carries an extremely powerful electrical charge, it can be destructive and deadly. It is difficult to know exactly how many people die of lightning-related causes. European researchers have estimated that between 6,000 and 24,000 people are killed by lightning worldwide each year. The strikes can also cause power failure, destroy property, damage electrical equipment and start forest fires.
For this reason, climate scientists have long sought to develop methods to predict and control lightning. The system tested in the experiments uses a combination of data from weather stations and machine learning methods. The researchers developed a prediction model that was trained to recognize weather conditions that were likely to cause lightning. The model was created with data collected over a 12-year period from 12 Swiss weather stations in cities and mountain areas. The data related to four main surface conditions: air pressure, air temperature, relative humidity (湿度) and wind speed. The atmospheric data was placed into a machine learning algorithm (计算程序), which compared it to records of lightning strikes. Researchers say the algorithm was then able to learn the conditions under which lightning happens.
“Once trained, the system made predictions that proved correct almost 80 percent of the time,” the Swiss Federal Institute of Technology said in a statement. “It can now be used anywhere.”
Amirhossein Mostajabi, a PhD student at the institute, said current systems for gathering such data are slow and complex and require costly collection equipment like radar or satellites. “Our method uses data that can be obtained from any weather station,” he said. “This will improve data collection in very remote areas not covered by radar and satellite or in places where communication systems have been cut,” he added.
The researchers plan to keep developing the technology in partnership with a European effort that aims to create a lightning protection system. Scientists working on the Paris-based project are experimenting with a laser technology that could someday control lightning activity. The idea is that powerful, ground-based lasers can be positioned in the sky to direct energy from lightning.
Which is the correct order of how the system works?
① develop a prediction model.
② learn to recognize weather conditions.
③ collect related data.
④ input the data onto the computer.
⑤ make predictions.

3 . After beating bone cancer, Hayley Arceneaux thinks rocketing into orbit on SpaceX’s first private flight should be no problem at all. St. Jude Children’s Research Hospital announced the 29-year-old doctor’s assistant will rocket into space later this year.
Arceneaux, a former patient at St. Jude, will become the youngest American in space, beating NASA record-holder Sally Ride by over two years. She will travel with businessman Jared Isaacman, who is using the spaceflight he bought to raise money for charity. Two other yet-to-be-chosen space flyers will join them. Arceneaux will be the first person to launch with a prosthesis an artificial device that replaces a missing or injured part of the body. When she was 10, Arceneaux had an operation at St. Jude to replace her knee and a piece of metal was put in her left leg. She still limps and has occasional leg pain.
“My battle with cancer really prepared me for space travel,” she recently told The Associated Press. “It made me tough, and then also I think it really taught me to expect the unexpected and go along for the ride.” Arceneaux wants to show her young patients and other cancer survivors that “the sky is not even the limit anymore.” “It’s going to mean so much to these kids to see a survivor in space.” she said.
Isaacman announced his space flight on February 1, promising to raise $200 million for St. Jude. As the flight’s self-appointed commander, he offered one of the four seats aboard SpaceX’s Dragon spacecraft to St. Jude. The hospital chose Arceneaux from among its many workers who had once been patients. The idea was that one of them could represent the new generation, noted Rick Shadyac, president of St. Jude’s financing organization.
Arceneaux was at home in Memphis, Tennessee, when she got a surprising call in January. She was asked if she would represent St. Jude in space. As a lifelong space fan who loves adventures, Arceneaux has traveled widely and loves roller coasters. Isaacman, who flies fighter airplanes for fun, considers her a perfect fit. The launch is planned for this fall at NASA’s Kennedy Space Center, with the spacecraft orbiting Earth for two to four days.

5 . Recently, a 1935 letter in which Ernest Hemingway detailed his catch of a 500lb blue marlin (青枪鱼), an adventure that is believed to have partly inspired his novel The Old Man and the Sea, has been sold for $28,000 (￡22,000).
...
Nate D Sanders, the auction (拍卖) company which sold the letter, said it documented for the first time in Hemingway’s own words not only the size of the marlin, but also the attack by sharks, reflecting the plot of the novel.
...
The Old Man and the Sea was also inspired by an anecdote told by Hemingway’s Cuban friend Carlos Gutierrez. In 1936, Hemingway wrote in a magazine ... about an old fisherman who caught a great marlin alone.
Three years later, Hemingway ... was planning a short story ... he was awarded the Nobel Prize in 1954.

6 . The history of microbiology begins with Dutch cloth maker named Antoni van Leeuwenhoek, a man of no formal scientific education. In the late 1600s. Leeuwenhoek, inspired by the magnifying lenses（放大镜）he used to examine cloth, built some of the first-microscopes. He developed technique to improve the quality of tiny, rounded lenses, some of which could magnify an object up to 270 times. After removing some plaque from between his teeth and examining it under a lens, Leeuwenhoek found tiny twisting creatures, which he called “animalcules”.
His observations, which he reported to the Royal Society of London, are among the first descriptions of microbes（微生物）. Leeuwenhoek discovered an entire universe invisible to the human eye. He found different microbes in samples of pond water, rain water, and human blood. He gave the first description of red blood cells, observed plant tissue, examined muscle, and investigated the life cycle of insects.
Nearly two hundred years later, Leeuwenhock’s discovery of microbes helped French chemist and biologist Louis Pasteur to develop his “theory of disease”. This concept suggested that disease originates from tiny organisms attacking and weakening the body. Pasteur’s theory later helped doctors to fight infectious diseases including anthrax, diphtheria, polio, smallpox, tetanus, and typhoid. All these breakthroughs were the result of Leeuwenhoek’s original work. Leeuwenhoek did not foresee this legacy.
In a 1716 letter, he described his contribution to science this way: “My work, which I’ve done for a long time, was not pursued in order to gain the praise I now enjoy, but chiefly from a strong desire for knowledge, which I notice resides in me more than in most other men. And therefore; whenever I found out anything remarkable, I have thought it my duty to put down my discovery on paper, so that the scientific community might be informed thereof.”

7 . Eat like a king in the morning, a prince at noon, and a peasant at night. This saying is all about the importance of breakfast. And now scientists can tell us just why it’s so important. According to a study carried out at Imperial College London, UK, skipping the first meal of the day not only means you eat more at lunch, but also that your brain wants to find more unhealthy foods.
The study suggests that there is a special part of our brain called the orbitofrontal cortex, which plays an important part in making choices about what we eat. It is used for identifying the taste of food, especially when skipping breakfast. It is more likely to target high-calorie foods when you’re on an empty stomach.
Scientists did an experiment on this. Dr Tony Goldstone from Imperial College London, scanned the brains of 21 men and women, around the age of 25. On the first day, these people skipped breakfast before the scans. On the second day, they had cereal, bread and jam as breakfast. After the scan on both days, they had their lunch.
When the volunteers had skipped breakfast, they ate around 20 percent more at lunch, compared with days when they had eaten breakfast. Their brain scans also showed the orbitofrontal cortex was especially responsive to high-calorie foods. “We believe that bit identifies the value of foods — how pleasant, how delicious something is,” Goldstone told The Guardian.

8 . A man in Brisbane, Australia, survived a house fire early Wednesday morning because his pet parrot, named Eric, sounded the alarm.
Anton was asleep when his home caught fire just after 2:00 a.m., according to the Australian Broadcasting Corporation (ABC). Anton didn’t hear the smoke detector(探测器). Instead, he heard Eric calling his name repeatedly, ABC reported. “I heard a bang and Eric — my parrot— he started to yell so I woke up and I smelled a bit of smoke,” Anton told ABC. “I grabbed Eric, opened the door and looked to the back of the house and saw some flames,” he added. “And so I grabbed my bag and bolted downstairs.” Officials told ABC that Anton’s home did have a smoke detector, but it didn’t go off before Eric started calling “Anton! Anton!” Queensland Fire and Emergency Services Acting Inspector Cam Thomas told ABC that the firemen were able to contain the fire before it spread to other properties(财产).
According to ABC, there may be a crime(犯罪)and policemen are looking into what caused the fire. In the meantime, Anton is glad that he and Eric survived. “I’m in shock but I’m fine,” he told ABC. “Everything’s all right so long as I have myself and the bird.”

9 . On the evening of June 21, 1992, a tall man with brown hair and blue eyes entered the beautiful hall of the Bell Tower Hotel in Xi’an with his bicycle. The hotel workers received him and telephoned the manager, for they had never seen a bicycle in the hotel ball before though they lived in “the kingdom of bicycles.”
Robert Friedlander, an American, arrived in Xi’an on his bicycle trip across Asia which started last December in New Delhi, India.
When he was 11, he read the book Marco Polo and made up his mind to visit the Silk Road. Now, after 44 years , he was on the Silk Road in Xi’an and his early dreams were coming true.
Robert Friedlander’s next destinations (目的地) were Lanzhou, Dunhuang, Urumqi, etc. He will complete his trip in Pakistan.

10 . The word "orange" describes both a color and a fruit. Which one came first might be surprising. "Orange" when used as the name of the fruit came before "orange" as a word to describe color. While the shade itself existed before the fruit, there was not a name in the English language for the color. Before the introduction of the fruit to English-speaking countries, the color was usually described as a shade of red or yellow.
In the early 16th century, Portuguese traders brought oranges from India to Europe. The Europeans had not seen the bright colored fruit before and didn't have a name for it. The fruits were named "narancia" by Italians and "narange" by the French and were sometimes referred to as "golden apples" by English speakers.
"Orange" was first used in a phrase to describe shades of colors, including in a third-century Greek text translated into English, in 1576. It describes Alexander the Great's servants as dressed in "orange colour velvet （天鹅绒）In 1578, a Latin-American dictionary defined "melites" as "a precious stone of orange color”. While orange represents the color of the objects, it needed the word "color" to follow it in order for the meaning to be clear. In the mid-1590s, Shakespeare described a beard as "orange tawny", one of the first instances of "orange" without the word "color" as part of the expression. Tawny is a brown color often used on its own. Orange was not yet a color, just a shade of brown.
In 1616, in an account describing varieties of tulips （郁金香）that can be grown, orange was used as a stand-alone color. When Isaac Newton performed his experiments on the color spectrum （色谱），he listed it as one of the seven basic colors. After almost half a century, orange was recognized as a color on its own.
