Dogs can be trained to identify the smell of lung cancer long before symptoms develop.
A new study is the first to show that sniffer dogs can be relied upon to find the unique smell of the disease of in 7 out of 10 sniffers. Researchers from a hospital in Germany believe dogs could become even better at picking out cancer cases with more training, but the final goal is to identify the cancer-specific chemical compounds the dogs can smell, and develop a device that could be used to help diagnose lung-cancer victims at an earlier stage.
Lung cancer is Britain’s deadliest cancer, with over 39.000 cases diagnosed annually, of which only 25 percent will survive for a year, since the disease is mostly found at an advanced stage, when it is very difficult to treat. Early detection is often by chance, although scientists have been working on using samples of exhaled(呼出的) breath from patients for future screening. They attempt to use the samples to locate volatile organic compounds(VOCs) in the breath that are linked to the presence of cancer, but no reliable methods have been found so far that are lung-specific.
The researchers combined this approach with recent findings about the abilities of some dogs to alert their owners to undiagnosed cancer, probably through smell. This latest study used family dogs, which were given special training over an 11-week period to identify a VOC in the breath of patient.
The researches worked with 220 volunteers, including patients with lung cancer at early and advanced stage, patients with chronic pulmonary disease(慢性肺炎), and healthy volunteers. The dogs took part in a number of tests to see if they could reliably distinguish compounds in the breath of lung-cancer patients-even if they smoked. The dogs were asked to sniff glass tubes containing cotton impregnated(浸染) with samples of breath from those taking part and had to lie down if they detected a VOC from a lung cancer patient.
The dogs successfully identified 71 samples with lung cancer out of a possible 100. They also correctly detected 372 samples that did not have lung cancer out of a posible 400.What can we conclude from the research according to the passage?
| A．The volunteers included patients with various cancer successfully |
| B．It used police dogs specially trained over a period. |
| C．It aimed to see if dogs could sniff cancer-specific compounds. |

In white shirt, blue pants, black cloth shoes and two pigtails (辫子), Jingqiu gives off an air of great “pure beauty” in Zhang Yimou’s new movie Under the Hawthom Tree.《山揸树之恋》
The film tells the story of the sad romance of Jingqiu and a handsome young man named Laosan. Set at the end of the “cultural revolution” (1966-1976), the pair manage to fall in love although they come form different political environments.
Before it was released, moviegoers speculated (推测) on just what this “pure beauty” could be. Director Zhang complained of how long it had taken him to find the right girl for the part of Jingqiu—a character so innocent that she believes simply lying on the same bed with a man will make her pregnant.
It was 18-year-old Zhou Dongyu who stood out from the crowd. According to Zhang, Zhou has “eyes that are clear like a fountain on a mountainside”. Born of an ordinary worker’s family, the Shijiazhuang girl was in her final year of high school and working hard for a place in an art college.
While some teenagers co
nsider such “pure beauty” illusory (虚幻的), others believe that it speaks of something soulful.
Purity is all about the innocence that shines through from within, thinks 16-year-old Tan Mengxi of Nanjing.
“Being pure can be simple, not having complicated thoughts and being inexperienced. However, it doesn’t mean an ignorant or naive (天真的) person. So, a person is pure in his or her nature if he or she is always enthusiastic and able to deal with difficult matters independently. This purity doesn’t pass with time,” she said. What image does Jingqiu give to audiences in the movie Under the Hawthorn Tree?
| A．A simple girl. | B．A pure girl. | C．A romantic girl. | D．A silent girl. |
What kind of girl looks pure according to the passage?
| A．A girl in red shirt, blue pants, black leather shoes and two pigtails. |
| B．A girl has eyes that are clear like a fountain on a mountainside. |
| C．A girl who was born into an ordinary worker’s family. |
| D．A girl wears accessories and make-up. |
What’s the opinion of Tan Mengxi about purity?
| A．It is of whether someone is ignorant or naive. |
| B．Being pure can be simple, not having complicated thoughts and being inexperienced. |
| C．It is of whether someone is always enthusiastic. |
| D．Purity is a matter of internal quality and doesn’t pass with time. |

THIS was the year the Earth struck back.
Earthquakes, heat waves, floods, volcanoes, super typhoons, snow storms, landslides and droughts killed at least a quarter of a million people in 2010 – the deadliest year in more than a generation. More people were killed worldwide by natural disasters this year than have been killed in terrorism attacks in the past 40 years combined.
"It just seemed like it was back-to-back and it came in waves," said Craig Fugate, who heads the U.S. Federal Emergency Management Agency. It handled a record number of disasters in 2010.
And we have ourselves to blame most of the time, scientists and disaster experts say.
Even though many catastrophes have the ring of random chance, the hand of man made this a particularly deadly, costly, extreme and weird（古怪的） year for everything from wild weather to earthquakes.
Poor construction and development practices conspire to make earthquakes more deadly than they need be. More people live in poverty in vulnerable（脆弱的） buildings in crowded cities. That means that when the ground shakes, the river breaches, or the tropical cyclone hits, more people die.
Disasters from the Earth, such as earthquakes and volcanoes "are pretty much constant," said Andreas Schraft, vice president of catastrophic perils for the Geneva-based insurance giant Swiss Re. "All the change that's made is man-made."
The January earthquake that killed well more than 220,000 people in Haiti is a perfect example. Port-au-Prince has nearly three times as many people - many of them living in poverty - and more poorly built shanties than it did 25 years ago. So had the same quake hit in 1985 instead of 2010, total deaths would have probably been in the 80,000 range, said Richard Olson, director of disaster risk reduction at Florida International University.
In February, an earthquake that was more than 500 times stronger than the one that struck Haiti hit an area of Chile that was less populated, better constructed, and not as poor. Chile's bigger quake caused fewer than 1,000 deaths.
Climate scientists say Earth's climate also is changing, bringing extreme weather, such as heat waves and flooding.
In the summer, one weather system caused oppressive heat in Russia, while farther south it caused flooding in Pakistan that inundated 161,200 square kilometers, about the size of Wisconsin. That single heat-and-storm system killed almost 17,000 people, more people than all the worldwide airplane crashes in the past 15 years.
Scientists have calculated that the killer Russian heat wave—setting a national record of 43.9℃—would happen once every 100,000 years without global warming.What is responsible for the most human deaths in 2010?
| A．Natrual disasters. | B．Terrorist attacks. |
| C．Poor buildings. | D．Too rapid developrnent. |

| A．earthquakes are happening more often because of human beings |
| B．earthquakes are causing more damage because of human beings |
| C．stronger houses should be built to limit storm damage |
| D．Port—au—Prince is now overpopulated |

| B．give the details of some natural disasters of 2010 |
| C．warn that more natural disasters are to strike |
| D．blame humanity for not helping those affected by the disasters |
Each time I see a balloon, my mind flies back to a memory of when I was a six-year-old girl. It was a rainy Sunday and my father had recently died. I asked my mom if Dad had gone to heaven. "Yes, honey. Of course." she said.
"Can we write him a letter?"
She paused, the longest pause of my short life, and answered, "Yes."
My heart jumped. "How? Does the mailman go there?" I asked.
"No, but I have an idea." Mom drove to a party store and returned with a red balloon. I asked her what it was for.
"Just wait, honey. You'll see." Mom told me to write my letter. Eagerly, I got my favorite pen, and poured out my six-year-old heart in the form of blue ink. I wrote about my day, what I learned at school, how Mom was doing, and even about what happened in a story I had read. For a few minutes it was as if Dad were still alive. I gave the letter to Mom. She read it over, and a smile crossed her face.
She made a hole in the corner of the letter where she looped (缠绕) the balloon string. We went outside and she gave me the balloon. It was still raining.
"Okay, on the count of three, let go. One, two, three."
The balloon, carrying my letter, darted upward against the rain. We watched until it was swallowed by the mass of clouds.
Later I realized, like the balloon, that Dad had never let his sickness get him down. He was strong. No matter what he suffered, he'd persevere, dart up, and finally transcend (超越) this cold world and his sick body. He rose into sky and became something beautiful. I watched until the balloon disappeared into the gray and white and I prayed that his strength was hereditar. I prayed to be a balloon.When the girl asked her mother if they could write to her father, her mother _________.

A TAXI driver taught me a million dollar lesson in custome
r satisfaction and expectation. Inspiring speakers charge thousands of dollars to give his kind of training to corporate directors and staff. It cost me only a ＄12 taxi ride.
I had flown into Dallas just for the purpose of calling on a client. Time was important and my plan included a quick turn – around trip from and back to the airport. A clean taxi pulled up.
The driver rushed to open the passenger door for me and made sure I was comfortably seated before he closed the door. As be got in the driver’s seat, he mentioned that the neatly folded Wall Street Journal next to me for my use. He then showed me several tapes and asked me what type of music I would enjoy.
Well! I looked around for a 
“Candid Camera!” Wouldn’t you? I could not believe the service I was receiving! I took the opportunity to say, “Obviously you take great pride in you work. You must have a story to tell.”

What is red but green, open but closed and old but new?
The answer is: London’s new double-decker（双层）buses.
Red double-deckers are a symbol of the city. Their status was sealed (确定) in 2008 when one bus made the longer-than-usual trip to Beijing to collect a special passenger: the Olympic Flame.
On November 11, a life-size model of the new bus was shown to the media. The Guardian reported that the new design shares some of the features of the much-missed double-decker Routemaster bus. The original Routemaster was introduced in 1956 but December 2005 saw the end of the old bus’s general service. It was because the bus was difficult for some passengers to use and not environmentally fr
iendly. But it can still be seen on two heritage routes in the city.
Its replacements —boxy, modern double—deckers—have failed to win Londoners’ affection.
London mayor Boris Johnson told the BBC that the new buses were “a combination of nostalgia（怀旧）and the latest technology”. “Standing on the back platform of this bus brings a sense of nostalgia but also shows the best part of the latest technology and design, making this bus fit for the 21st Century,” he said.
The new bus also returns to the driver—and—conductor model—a key feature of the original version. It will be quieter than the old type and have a platform offering passengers the traditional hop—on hop—off service.
The first five new buses will be seen on the roads by early 2012.Which of the following shows that red double—deckers are a symbol of London?
| A．They have a long history and are seen everywhere in London. |
| B．They have nothing in common with the traditional Routemaster bus. |
| C．One such bus went from London to Beijing to collect the Olympic Flame. |
| D．They carried British athletes from London to attend the Beijing Olympics. |
Which of the following is true of the original Routemaster?
| A．The bus came into use in the 1960s. |
| B．The bus was banned because it was harmful to the environment. |
| C．Passengers didn’t like the bus because it was slow. |
| D．Visitors to London cannot see such buses on the roads any more. |
According to London mayor Boris Johnson, the new Routemaster .
| A．has not been as well received as was expected |
| B．will be widely used in London in 2012 |
C．is the mo st environmentally friendly bus in the UK |
| D．combines the latest technology with key traditional features |
What is the characteristic of the new red double – deckers?
| A．The buses will make no noises. |
| B．The buses will have no conductors. |
C．They will be equipped with air – conditioning. |
| D．The bus platform will offer passengers a traditional service. |
