Home fires can happen quickly, destroying lives and property, but unlike other disasters, most home fires can be prevented. Read on to learn 4 unexpected home fire dangers.
Having old smoke alarms
An effective smoke alarm can make much difference when it comes to surviving a house fire. It’s not enough to change the batteries twice a year, you also need to replace your alarms every decade. “You should test your smoke alarms every month,” says Lorraine Carli, vice president of the National Fire Protection Association. “But also don’t forget to check the dates and replace an alarm that is more than 10 years old.”
Leaving the kitchen while you cook
One in five Americans admitted leaving food cooking unattended on the stove, found an American Red Cross survey. Walking away from food cooking in the kitchen is a serious fire risk. “The leading cause of home fires is cooking and the leading cause of those fires is unattended cooking,” says Carli.“If you need to use the stove or oven, be sure to keep an eye on it.”
Turning the heat too high when you cook
Turning up the heat too high can be deadly, even if you’re in the kitchen while you cook. Kevin Kelley, senior director of the American Red Cross, recommends paying close attention and turning off the burner if you see smoke or grease (油脂) starting to boil while frying food.
Having a dirty stove while you cook
If your stove is covered with grease, a small kitchen fire can get out of hand quickly. Clean and clear the area around the stove before turning on the heat, or the result will be dangerous.
1. How long should you have a new smoke alarm?| A．2 years. | B．10 years. | C．12 years. | D．8 years. |
| A．Clearing a dirty stove. | B．Turning off the burner . |
| C．Replacing an alarm. | D．Unattended cooking. |
| A．Unexpected home fire dangers can be prevented. |
| B．It is advisable to change the batteries twice a year. |

But self-punishment doesn’t encourage growth, says Katherine, a psychotherapist and author of “The Perfectionist’s Guide to Losing Control.”
Instead of punishing yourself for making a mistake, it is more effective to practice self-compassion(自我同情). Katherine suggests the broaden-and-build theory, a positive psychology theory that was developed by social psychologist Barbara in 1998.
Broaden-and-build theory suggests that when you’re in a positive headspace you feel more able to face different challenges and make choices based on the possibility of positive outcomes. When you’re in a negative headspace your view narrows and you aren’t inspired or encouraged to think differently.
Research demonstrates self compassion’s positive association with a greater sense of self-worth, more realistic self-evaluations of strengths and weaknesses, lower levels of depression and anxiety.
| A．In other words, you’re punishing yourself. |
| B．“Punishment doesn’t work.” she writes in her book. |
| C．To put yourself in a positive headspace, you need to practice self-compassion. |
| D．If you are the source of your own punishment then you learn to avoid yourself. |
| E．Punishment can be mistaken for a handful of things like discipline, personal responsibility. |
| F．It is also related with increased motivation to learn from past mistakes, and the list goes on. |
| G．Instead of being scared to act natural consequence might encourage you to act in a way leading to a positive result. |
【推荐2】It is well known that the Japanese people’s love of fish is almost as strong as a bee’s interest in honey. As fish populations were becoming smaller and smaller, fishing companies were forced to fish further and further away from the shore. Then they had a big challenge — how to keep the fish fresh for longer. So they decided to keep the fish stored in freezers on the boats. But the public did not like frozen fish. So again the fishing companies had a new bigger challenge. What they decided to do was to have fish tanks on their boats. After catching fishes, they would put them in the tanks and keep them living there until they got back to shore. But in this protected environment, lacking predators (掠食者), the fish stopped moving around. The Japanese public felt these dull fish did not taste fresh, which had an unpleasant effect upon sales. Once again the fishing companies had an even bigger challenge …
Stop for a minute! Before we go any further, I would like to ask “What are your challenges? How do you handle an unexpected challenge? ” May I think it this way that you should try to attack your challenges? Conquer(征服) them with a Swiss Army knife. Take the most proper and simple tool that you can adopt to deal with your situation.
Now back to our story. How did the Japanese finally solve the fresh fish problem? Sharks! You might think the same. Sharks were caught and put into the tanks with other fishes. Don’t sharks eat fish? Well, they do eat a few fish, but they did also keep more fish active and alert (警觉的). The fish stay fresh because they are challenged.
Now, try to keep yourself fresh by finding your own shark to offer yourself a challenge in your own business and career.

【推荐3】Being “a grown-up” is a pretty unclear concept, even once you’re technically “grown-up”. My career has taken its fair share of twists and turns in the past three years since I graduated, and in some ways I feel like I’m still only starting to figure out what I want to do.
In some ways, in decision about the future allows you to have a much more open mind about various career choices than those who’ve always known exactly what they want to do. If you limit yourself too much, you could miss the opportunity to join an exciting new startup, develop a great business idea, or try something unexpected that you might love.
Accept that the landscape is always changing
While it may have once made sense to dream about being a doctor, lawyer, or professional ballet dancer, many of the jobs open to you now are ones you didn’t know about as a child.

【推荐1】Mr. Peter Johnson, aged twenty-three, battled for half an hour to escape from his trapped car yesterday when it landed upside down in three feet of water. Mr. Johnson took the only escape route-through the boot(行李箱).
Mr. Johnson’s car had finished up in a ditch(沟渠) at Romney Marsin, after skidding on ice and hitting a bank. “Fortunately, the water began to come in only slowly,” Mr. Johnson said. “I couldn’t force the doors because they were jammed against the walls of the ditch and dared not open the windows because I knew water would come flooding in.”
Mr. Johnson, a sweet salesman of Sitting Home, first tried to attract the attention of other motorists by sounding the horn and hammering on the roof and boot. Then he began his struggle to escape.
Later he said, “It was really a half penny that saved my life. It was the only coin I had in my pocket and I used it to unscrew the back seat to get into the boot. I hammered desperately with a hammer trying to make someone hear, but no help came.”
It took ten minutes to unscrew the seat, and a further five minutes to clear the sweet samples from the boot. Then Mr. Johnson found a wrench(扳手)and began to work on the boot lock. Fifteen minutes passed by. “It was the only chance I had. Finally it gave, but as soon as I moved the boot lid, the water and mud poured in. I forced the lid down into the mud and scrambled clear as the car filled up.”
His hands and arms cut and bruised(擦伤), Mr. Johnson got to Beckett Farm nearby, where he was looked after by the farmer’s wife, Mrs. Lucy Bates. Huddled in a blanket, he said, “That thirty minutes seemed like hours.” Only the tips of the car wheels were visible, police said last night. The vehicle had sunk into two feet of mud at the bottom of the ditch.

【推荐2】“What is civilization?” asked Kenneth Clark 50 years ago in the BBC series on the subject. “I don’t know, and I can’t define it in abstract terms, yet. But I think I can recognise it when I see it, and I’m looking at it now.” And he turned to gesture behind him, at the soaring Gothic towers and flying buttresses of Notre Dame.
It seems inhuman to care more about a building than about people. That the sight of Notre Dame going up in flame has attracted so much more attention than floods in southern Africa which killed over 1,000 arouses understandable feelings of guilt. Yet the widespread, intense grief at the sight of the cathedral’s collapsing steeple (尖塔) is in fact profoundly human—and in a particularly 21st-century way.
It is not just the economy that is global today, it is culture too. People wander the world in search not just of jobs and security but also of beauty and history. A building on whose sunny steps you have rested, in front of which you have taken a selfie with your loved one, becomes a warm part of your memories and thus of yourself. That helps explain why China is in mourning—WeChat, young China’s principal means of talking to itself, has been throbbing with the story, and XiJinping, the country’s president, sent a message of condolence (慰问) to Emmanuel Macron, his French counterpart—while India was largely indifferent. Tourism from India to the West is a stream compared with the flood from China.
This visual age has blessed beauty with new power, and social media have turned great works of art into superstars. Only a few, though, have achieved this status. Just as there is only ever a handful of world-famous actors, so the number of globally recognisable cultural symbols is tiny: the Mona Lisa, Michelangelo’s David, the Taj Mahal, the Great Pyramid—and Notre Dame. Disaster, too, is visual. In the 24 hours after the fire started videos on social media of the burning cathedral were viewed nearly a quarter of a billion times.
Yet the emotions the sight aroused were less about the building itself than about what losing it might mean. Notre Dame is an expression of humanity at its collective best. Nobody could look up into that vaulted ceiling without wondering at the genius of the thousands of anonymous craftsmen who, over a century and a half, realised a vision so grand in its structural ambition and so delicate in its hand-chiselled detail. Its survival through 850 years of political turbulence—through war, revolution and Nazi occupation—binds the present to the past.
The fire also binds people to each other. The outpouring of emotion it has brought forth is proof that, despite the dark forces of division now abroad, we are all in it together. When nationalism is a rising threat, shared sadness makes borders suddenly irrelevant. When politics is polarised, a love of culture has the power to unite. When extremism divides Muslim from Christian and religious people from atheists, those of all faiths and none are mourning together. An edifice (宏伟建筑) built for the glory of God also represents the unity of the human spirit.
And it will be rebuilt. The morning after the fire, the many Parisians who went to the cathedral to mourn its destruction found comfort instead. Although the spire is gone, the towers are still standing and it seems likely that the whole building can be revived. The effort to rebuild it, like the fire, will bring people together. Within 24 hours,￡6000m ($677m) had been raised from businesses and rich people, and a lot of crowdfunding campaigns started. A high-resolution laser scan of the building, carried out recently, should help.
It will never be the same, but that is as it should be. As Victor Hugo wrote in “The Hunchback of Notre Dame”, a three-volume love-letter to the cathedral: “Great edifices, like great mountains, are the work of centuries. Art is often transformed as it is being made...Time is the architect, the nation is the builder.”

【推荐3】A new collection of photos brings an unsuccessful Antarctic voyage back to life.
Frank Hurley’s pictures would be outstanding — undoubtedly first-rate photo-journalism — if they had been made last week. In fact, they were shot from 1914 through 1916, most of them after a disastrous shipwreck (海难), by a cameraman who had no reasonable expectation of survival. Many of the images were stored in an ice chest, under freezing water, in the damaged wooden ship.
The ship was the Endurance, a small, tight, Norwegian-built three-master that was intended to take Sir Ernest Shackleton and a small crew of seamen and scientists, 27 men in all, to the southernmost shore of Antarctica’s Weddell Sea. From that point Shackleton wanted to force a passage by dog sled (雪橇) across the continent. The journey was intended to achieve more than what Captain Robert Falcon Scott had done. Captain Scott had reached the South Pole early in 1912 but had died with his four companions on the march back.
As writer Caroline Alexander makes clear in her forceful and well-researched story The Endurance, adventuring was even then a thoroughly commercial effort. Scott’s last journey, completed as he lay in a tent dying of cold and hunger, caught the world’s imagination, and a film made in his honor drew crowds. Shackleton, a onetime British merchant-navy officer who had got to within 100 miles of the South Pole in 1908, started a business before his 1914 voyage to make money from movie and still photography. Frank Hurley, a confident and gifted Australian photographer who knew the Antarctic, was hired to make the images, most of which have never before been published.

【推荐1】A 15-year-old Colorado high school student and young scientist who has used artificial intelligence (AI) and created apps to address polluted drinking water, drug addiction and other social problems has been named Time Magazine’s first-ever “Kid of the Year”.
Rao told The Associated Press in an interview from her home that the prize is nothing that I could have ever imagined. And I’m so grateful and just so excited that we’re really taking a look at the upcoming generation and our generation, since the future is in our hands.
Time said Rao stood out for creating a global community of young innovators and inspiring them to pursue their goals. Rao insisted that starting out small doesn’t matter, as long as you’re passionate about it.
She told Time contributing editor Angelina Jolie in an interview that her science pursuits started early as a way to improve social conditions. The drinking water crisis in Flint, Michigan, inspired her work to develop a way to detect pollutants and send those results to a mobile phone, she said.
“I was like 10 when I told my parents that I wanted to research carbon nanotube sensor technology at the Denver Water quality research lab, and my mum was like, A what?” Rao told Jolie. She said that work is going to be in our generation’s hands pretty soon. “So if no one else is gonna do it, I’m gonna do it.”
In a world where science is increasingly questioned or challenged, Rao insisted that its pursuit is an act of kindness, the best way that a younger generation can better the world.
“We have science in everything we’re involved in, and I think that’s the biggest thing to put out there, that science is cool, innovating is cool, and anybody can be an innovator.” Rao said, “Anybody can do science.”
1. What did Rao think of the award she received?| A．It was a mark of social progress. | B．It was a recognition of her work. |
| C．It was an inspiration to the youth. | D．It was a title beyond her expectation. |

【推荐2】Recognizing when a friend or colleague feels sad, angry or surprised is key to getting along with others. But a new study suggests that being sensitive to people’s feelings may sometimes come with stress, challenging the popular view that emotional intelligence is uniformly beneficial to its bearer.
In the study, psychologist Myriam Bechtoldt of the Frankfurt School of Finance and Management in Germany asked 166 male university students a series of questions to measure their emotional intelligence. For example, they showed the students photographs of people’s faces and asked them to what extent feelings such as happiness or disgust were being expressed. The students then had to give job talks in front of judges who displayed serious facial expressions. The scientists measured concentrations of stress hormones (荷尔蒙) in the students’ saliva (唾液) before and after the talk.
In students who were rated more emotionally intelligent, the stress measures increased more during the experiment and took longer to go back to baseline. The findings suggest that some people may be too emotionally clever for their own good, says Bechtoldt, “Sometimes you can be so good at something that it causes trouble,” she notes.
Indeed, the study adds to previous research implying a dark side of emotional intelligence. A study published in 2002 in Personality and Individual Differences suggested that emotionally intelligent people might be particularly influenced by feelings of depression and hopelessness. Furthermore, several studies have implied that emotional intelligence can be used to manipulate others for personal gains.
More research is needed to see how exactly the relation between emotional intelligence and stress would play out in women and in people of different ages and education levels. Nevertheless, emotional intelligence is a useful skill to have, as long as you learn to also properly cope with emotions — both others’ and your own, says Bechtoldt. For example, some sensitive individuals may assume responsibility for other people’s sadness or anger, which ultimately stresses them out. Remember, as Bechtoldt says, “You are not responsible for how other people feel.”
1. What was the purpose of Myriam Bechtoldt’s experiment?| A．To define different types of human feelings. |
| B．To assess the impacts of being emotionally clever. |
| C．To demonstrate how to distinguish different feelings. |
| D．To identify gender differences in emotional intelligence. |

Some of the most important helpers in the job of good health are the substances we call vitamins. The word “vitamin” dates back to Polish scientist Casimir Funk in 1912. He was studying a substance in rice. Funk believed the substance belonged to a group of chemicals known as amines (胺类). He added the Latin word “vita”, meaning life. So he called the substance a “vitamine”—an amine necessary for life.
Other studies found that not all vitamins were amines. So the name was shortened to vitamin. But Funk was correct in recognizing their importance.
Scientists have discovered 14 kinds of vitamins. They say vitamins help to carry out chemicals changes within cells. If we do not get enough of the vitamins, we are at risk of developing a number of diseases. This brings us back to James Lind of Scotland. In the 1740s, Lind was a doctor for the British Navy. He was investigating a problem that had existed in the Navy for many years.
The problem was the disease scurvy(坏血病). The sailors were weak from bleeding inside their bodies. Even the smallest wound would not heal. Doctor Lind thought the sailors were getting sick because they failed to eat some kinds of foods when they were at sea for many months.
Doctor Lind separated twelve sailors who had scurvy into two groups. He gave each group different foods to eat. One group got oranges and lemons. The other did not. The men who ate the fruit began to improve within seven days. The other men got weaker.
However, which foods should be eaten to keep us healthy? Let us look at some important vitamins for these answers.
1. Why was the name “vitamine” shortened to “vitamin”?
| A．Because Funk was totally wrong. |

【推荐2】The fight is on to get rid of air pollution in our cities. While the best solution in the long-term would be to ban fossil-fueled cars, that won’t help the millions who are dying in the meantime, and so some high-tech solutions are now on the cards.
London’s air pollution problem has been getting worse for years. In March 2016, ten London pigeons became famous. These pigeons took to the sky, wearing backpacks monitoring air pollution. Once in the air, the backpacks sent live air-quality updates to the smartphones of the Londoners below.
Another promising approach can be found in Beijing. A seven-metre-high “Smog Free Tower”, designed by a Dutch scientist, Daan Roosegaarde, opened in Beijing’s 751 D Park in September 2016. It is a huge, outdoor air purifier. Airborne particles (颗粒) are sucked into the tower and caught by a dust-removal plate. Finally, clean air is blown out of the other end. “Changing smog particles does not take much power.” Roosegaarde said.
As for what to do with the collected PM waste, he has currently set up a business making jewellery out of the waste. Prince Charles owns a set of “smog free” cufflinks (袖扣). If collected on at a big scale, Roosegaarde believes it could even be used as a building material.
Mexico City has an alternative solution. Looking to Nature to maximize the surface area of a building, Allison Dring, a Berlin-based architect, managed to catch light and wind from all sides. She is now making a building material by burning agricultural crop by-products in the absence of oxygen. “It means that you are actually taking carbon (碳) out of the sky, transforming it into a material, and then using it to build,” says Dring.
The fight against outdoor air pollution is really just starting. Even if none of the ideas take off, at least Prince Charles’ cufflinks, the special building surface and pigeons wearing back-packs will have brought the issue more to the public’s attention.

【推荐3】If you want to become a fluent English speaker you should take some advice. There are four skills in learning English. They are reading, listening, speaking, and writing. The most important thing you must remember is that if you want to improve your speaking and writing skills you should first master the skills of reading and listening.
Read as much as you can. But your reading must be active. It means that you should understand the meaning of the sentence. There is no need for you to pay much attention to grammars or try to understand all the unfamiliar words you come across, but the fact that you see them for the first time and recognize them whenever you see them, for example, in other passages or books, is enough. It would be better to prepare yourself a notebook so you can write down the important words or sentences in it.
As for listening, there are two choices: besides reading, you can listen every day for about 30 minutes. You can only pay attention to your reading and become skillful at your reading, and then you can catch up on your listening. Since you have lots of inputs (输入) in your mind, you can easily guess what the speaker is going to say. This never means that you should not practice.
For listening you can listen to cartoons or some movies that are specially made for children. Their languages are easy. Or if you are good at listening you can listen to VOA or BBC programs every day. Again the thing to remember is being active in listening and preferably taking some notes.
If you follow these pieces of advice, your speaking and writing will improve automatically, and you can be sure that with a little effort they will become perfect.
1. According to the writer, which should you improve first among the four skills?| A．Reading and listening. | B．Reading and writing. |
| C．Writing and speaking. | D．Speaking and listening. |
| A．look up all the new words in the dictionary |
| B．think about what you are reading actively |
