A technique that controls immediate gas explosions by spraying them with large droplets of water is being tested by scientists at the University of Wales, United Kingdom．Instead of using the traditional fine water sprays when a gas leak is detected, the researchers have discovered that large droplets help to draw in some of the force of any explosion and provide a better way of controlling fire．
The research is based on studies made of the Piper Alpha oil rig （油井） explosion that occurred in the North Sea nine years ago killing 167 workers．The Welsh team found that by covering the gas-leak area with water droplets, the explosion and its effect can be greatly reduced．
Dr Gerand Thomas, a good lecturer in physics at the university’s Center for Explosion Studies, said that it was impossible to deal with gas explosions in the same way as fires because the whole event may only last a quarter of a second and normal water sprays do not have time to be effective．
Using the droplets of water to hold explosions resulted in the water being turned into a mist that allows some force of the explosion to be reduced．The mist slows down the combustion （燃烧） process and can stop a large amount of the gas igniting （点火,燃烧）, thus greatly reducing damage by limiting pressure development．With such a system, the operator has to decide at what point after a gas leak to activate the sprays．
The Center for Explosion Studies is the first of its kind in the UK and has been purposely-built for the study and implication of industrial explosions on land and sea．Research is developed to the causes of accidental explosions and they might be prevented．Full-sized imitative buildings can be built at the center where explosions and fires are created to test preventative equipment using sensors to monitor their efficiency．
Another area that the Welsh researchers have been looking at is how materials respond to explosions．The center also carries out research requested by individual customers．

In 1943, when I was 4, my parents moved from Coeur d'Alene, Idaho, to Fairbanks, Alaska, where adventure was never very far away.
We arrived in the summer, just in time to enjoy the midnight sun. All that sunlight was fantastic for Mom's vegetable garden. Working in the garden at midnight tended to throw her timing off, so she didn't care much about my bedtime.
Dad was a Railway Express agent and Mom was his clerk. That left me in a mess（混乱）. I usually managed to find some trouble to get into. Once I had a little fire going in the dirt basement of a hotel. I had tried to light a barrel（桶） of paint but couldn't really get a good fire going. The smoke got pretty bad, though, and when I made my exit, a crowd and the police were there to greet me. The policemen took my matches and drove me home.
Mom and Dad were occupied in the garden and Dad told the police to keep me, and they did! I had a tour of the prison before Mom rescued me. 1 hadn't turned 5 yet.
As I entered kindergarten, the serious cold began to set in. Would it surprise you to know that I soon left part of my tongue ( 舌头 )on a metal handrail at school?
As for Leonhard Seppala, famous as a dog sledder (驾雪橇者), I think I knew him well because I was taken for a ride with his white dog team one Sunday. At the time I didn't realize what a superstar he was, but I do remember the ride well. I was wrapped (包裹) heavily and well sheltered （保护） from the freezing and blowing weather.
In 1950, we moved back to Coeur d'Alene, but we got one more Alaskan adventure when Leonhard invited us eight years later by paying a visit to Idaho to attend a gathering of former neighbors of Alaska.What can be inferred about the author's family?

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 traditional chest compressions (按压) until the ambulance（救护车）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 afraid. 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 (发作)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 （康复）from his suffering.Izzy kicked her father in the chest ______ .
| A．to express her helplessness |
| B．to practise CPR on him |

Half of the world’s population lives in areas affected by Asian monsoons（季风）, but monsoons are difficult to predict. American researchers have put together a 700-year record of the rainy seasons, which is expected to provide guidance for experts making weather predictions.
Every summer, moist（潮湿的）air masses, known as monsoon, produce large quantities of rainfall in India, East Asia, Indonesia, Northern Australia and East Africa, which are pulled in by a high pressure area over the Indian Ocean and a low pressure area to the south.
According to Edward Cook, a weather expert at Columbia University in New York, the complex nature of the climate systems across Asia makes monsoons hard to predict. In addition, climate records for the area date to 1950, too recent and not detailed enough to be of much use. Therefore, he and a team of researchers spent more than fifteen years travelling across Asia locating trees old enough to provide long-term records. They measured the rings（年轮）or circles, inside the trunks of thousands of ancient trees at more than 300 sites.
Rainfall has a direct link to the growth and width of rings on some kinds of trees. The researchers developed a document—a Monsoon Asia Drought Atlas（地图集）. It shows the effect of monsoons over seven centuries, beginning in the 1300s.
Professor Cook says the tree-ring records show periods of wet and dry conditions. “If the monsoon basically fails or is very weak one year, the trees affected by the monsoon at that location might put on a very narrow ring. But if the monsoon is very strong, the trees affected by that monsoon might put on a wide ring for that year. So, the wide and narrow ring widths of the tree chronology（年表）that we developed in Asia provide us with a measure of monsoon variability. ” Armed with such a sweeping set of data, researchers say they now can begin to refine climate computer models for predicting the behavior of monsoons.
“There has been widespread famine and starvation and human dying in the past in large droughts. And on the other hand, if the monsoon is particularly heavy, it can cause extensive flooding,” said Eugene Wahl, a scientist who is with America’s National Oceanic and Atmospheric Administration’s paleoclimate（古气侯）branch studying weather patterns over the history of the Earth. “So, to get a knowledge of what the regional moisture patterns have been, dryness and wetness over such a long period of time in great detail, I would call it a kind of victory for climate science.”What’s the passage mainly about?

Where Are We Going, Dad? has become one of China’s most popular television shows, since its debut（首次登场）in October, averaging more than 600 million viewers each week. Sponsorship rights（冠名权）for the show’s second season were sold for 312 million yuan（about $ 50 million）, more than ten times higher than the rights to the first season.
What accounts for its popularity? The show features a mew generation of Chinese fathers, who, as part of the country’s new middle class, have faced more problems with modern child-raising techniques such as taking an active role with their children.
Part of the appeal of the show is the chance to throw a glance at the lives of Chinese celebrities（名流）and their children. Audiences are interested in watching the failed attempts of celebrity dads making dinner, doing hair, and disciplining（管教）children — tasks often left to mothers in a society still influenced by the saying that “men rule outside and women are inside.” “In traditional Chinese culture, fathers are strict and mothers are kind. But on the show, we see fathers who are much gentler on their kids and more involved in their upbringing,” said Li Minyi, an associate professor. “This show raises an important question for modern Chinese society — what is the role of fathers in today’s China?”
After each episode（集）goes to air, the Chinese Internet explodes with comments on each celebrity’s parenting style.
Actor Guo Tao tries to communicate with his son, Shitou, but is seen as a more traditional Chinese father, and has been criticized online for being too harsh. Zhang Liang, a supermodel, is an audience favorite for treating his son, Tiantian, more like a friend. The show’s most famous celebrity, Lin Zhiying, a film star, was originally praised as patient with his son Kimi. But as the season progresses, fans begin to criticize him for raising a spoiled, undisciplined boy. Director Wang Yuelun is at a complete loss when it comes to care of his daughter’s hair.
Even the People’s Daily is pleased with the success of the show.Sponsorship rights for the show’s first season were sold for ________.
| A．312 million yuan |
| B．about 50 million yuan |
| C．more than 600million yuan |
| D．about 30million yuan |
According to the passage, the show_________.
| A．gives audiences the chance to raise the stars’ children themselves |
| B．invites some famous film stars to take part in it |
| C．lets people think about the role of fathers in modern families |
| D．raises people’s concern about women’s role in the society |
The underlined word “harsh” in the fifth paragraph most probably means “_____”.
| A．careless | B．strict | C．clumsy | D．kind |
According to the writer, _________ is the most successful father.
| A．Zhang Liang | B．Guo Tao |

People in the United States love their dogs and treat them well. They take their dogs for walks, let them play outside and give them good food and medical care. However, dogs without owners to care for them lead a different kind of life. The expression, “to lead a dog’s life”, describes a person who lives an unhappy life.
Some people say we live in a dog-eat-dog world. That means many people are competing for the same things, like good jobs. They say that to be successful, a person has to work like a dog. This means they have to work very, very hard. Such hard work can make people dog-tired. And, the situation would be even worse if they became sick as a dog.
Still, people say every dog has its day. This means that every person enjoys a successful period during his or her life. To be successful, people often have to learn new skills. Yet, some people say that you can never teach an old dog new tricks. They believe that older people do not like to learn new things and will not change the way they do things.
Some people are compared to dogs in bad ways. People who are unkind or uncaring can be described as meaner than a junkyard dog. Junkyard dogs live in places where people throw away things they do not want. Mean dogs are often used to guard this property. They bark at or attack people who try to enter the property. However, sometimes a person who appears to be mean and threatening is really not so bad. We say his bark is worse than his bite.
Husbands and wives use this doghouse term when they are angry at each other. For example, a woman might get angry at her husband for coming home late or forgetting their wedding anniversary. She might tell him that he is in the doghouse. She may not treat him nicely until he apologizes. However, the husband may decide that it is best to leave things alone and not create more problems. He might decide to let sleeping dogs lie.
Dog expressions also are used to describe the weather. The dog days of summer are the hottest days of the year. A rainstorm may cool the weather. But we do not want it to rain too hard. We do not want it to rain cats and dogs.To achieve success, you must____________.
| A．work like a dog |
| B．feel dog-tired |
| C．become sick as a dog |
| D．be meaner than a junkyard dog |
