XI’AN – China has introduced various emergency responses and long-term measures against air pollution in the central and eastern regions.
The air quality index (AQI) for Xi’an reached 500 on Wednesday afternoon, at the top of the AQI scale, according to the national air quality monitoring website. Xi’an weather forecasters predict the smog (霧霾) will continue for the next week and air pollution may worsen.
“I have to keep buying masks for my family,” said Liu, buying masks at a pharmacy (藥店) near her home in downtown Xi’an. “This is the only thing we can do to protect ourselves.”
On Wednesday, a city government emergency response plan was put into action, suspending all construction and taking at least 50 percent of government vehicles off the road. Power plants must limit their output and reduce emissions.
Nearly half the country, more than 100 cities in 20 provinces, has suffered from smog since last December. Many have taken action, including experimenting with artificial methods to reduce smog, limiting vehicle use and fining polluters.
Assessments based on GDP alone were abandoned last month and more emphasis has been put on public well-being and the environment. Whether the move will be effective in forcing local governments consider environmental issues over economic growth remains to be seen. Environmental protection professionals are doubtful about the immediacy of the effects of these measures.
Xiao Hang, an urban researcher at the Chinese Academy of Sciences, said it took London 50 years to lose the moniker (綽號) “foggy London town”, and Los Angeles still struggles to control its photochemical (光化學) smog. “We can’t ignore environmental problems during the development process and China has a long way to go,” he said.
小題1:What would be the best title for the article?
A．AQI for Xi’an reached 500
B．Smog crisis tries the limits of people’s patience
C．Smoggy Chinese cities to clear the air
D．Dust masks become hot sellers

A．China is the only country suffering from smog
B．environmental professionals believe the air quality will soon be improved with these measures
C．assessments based on GDP alone were harmful to environmental protection
D．Xi’an was the most polluted city in China
小題4:What Xiao Hang said indicates _____________.
A．London still has serious air pollution after 50 years of effort
B．the development of China is more important

All it took was a slice of Xinjiang cake to spark heated debates online over China's policy on ethnic minorities (少數(shù)民族) .
Since Monday, qiegao (cut cake) has been a trending topic on Sina Weibo, China’s main Twitter-like microblogging service.
The cake was a reference to Xinjiang’s famed nut cake, sometimes known by its old Turkic name baklava, a popular pastry across Central Asia and the Middle East. In Xinjiang, they are sold by Uygur vendors on tricycles who are known to charge dubious prices depending on the time and season.
The ethnic flare-up started after the Yueyang police from Hunan province posted a message on their official Weibo account. It reported a dispute in Pingjiang county over an overpriced piece of nut cake between a Xinjiang Uygur vendor and a villager named "Ling".
Villager Ling got into a fight with a Uygur due to a misunderstanding. The verbal dispute eventually escalated into a fight and then a mass fight. As a result, two people were injured and Xinjiang nut cakes worth about 160,000 yuan (US$25,000) were destroyed. The total damage was worth 200,000 yuan which included a broken motorcycle and injuries to people. Local police have detained Ling. The 16 Uygur sellers were dully compensated and sent back to Xinjiang.
"Yueyang police incident" quickly became one of the most popular topics on Weibo. Yueyang police removed the post shortly after. As of Tuesday night, the topic was still amassing more than 66,000 hits. 
The incident is just one of many similar cases of ethnic tensions across China, notably in Xinjiang province, where deeply entrenched social and racial frictions between the dominant ethnic Han Chinese and minority Uygur Muslims occasionally spark violence. Many Uygurs living in major Chinese cities are viewed by locals as thieves, crooks and even terrorists.
小題1:Which of the following is true?
A．The dispute is between a Xinjiang Uygur vendor and a policeman.
B．Nut cake is a popular pastry across East Asia and the Middle East.
C．The prices of Baklava will change according to the time and season.
D．The demand of the 16 Uygur sellers were refused and they were sent back to Xinjiang.
小題2:How much did the broken motorcycle cost？
A．160,000 yuan B．200,000 yuan C．40,000yuan D．We don’t know
小題3:What’s the best title of the passage?
A．World's most expensive baklava
B．Ethnic tensions across China
C．Pay attention to the Uygurs
D．Misunderstanding caused a fight
小題4:What can we infer from the passage?
A．Yueyang police are afraid of the Xinjiang Uygur vendor
B．It’s not the only ethnic tension across China,
C．Many Uygurs living in major Chinese cities are viewed by locals as thieves, crooks and even terrorists.
D．Villager Ling got into a fight with a Uygur due to a misunderstanding.

A father with Parkinson's disease was arrested as he watched the Olympic cycling road race because he failed to smile or look as if he was enjoying himself.
Mark Worsfold, a martial arts trainer and former soldier, claims that he was thrown to the floor and handcuffed just as cyclists passed by. His worried wife Nicola only found out he was being held after she reported him missing when he did not turn up for their daughter's ninth birthday party. The 54­year­old man had his fingerprints, DNA and mugshot taken before being questioned about why he did not appear to be enjoying the event on July 28. Police said Mr. Worsfold, who was held for over five hours, was arrested because of his manner，his state of dress and his being too near to the course. A spokesman added that the arrest was necessary to avoid a breach(破壞) of the peace because he was standing near a group of protesters(抗議者)．
But Mr. Worsfold, who was diagnosed with Parkinson's disease in 2010, said that one of the symptoms of the disease is muscle rigidity, which can cause his face to become expressionless. “I was sitting minding my own business”， he told a local newspaper. “Before I knew anything the police grabbed me off this seven­foot wall, threw me to the floor and handcuffed me, so all I saw of the cycle race was between the feet of people from the pavement. It could have been done better. I was arrested for not smiling. I have Parkinson's disease.”
Mr. Worsfold has since asked for a letter of not being guilty from police. The officers who made the arrest have apologized to him.

The illegal ivory trade has been a major problem in Africa for decades. Poachers(偷獵者) and hunters have killed off hundreds of thousands of elephants to obtain this precious material. Now, affected areas are taking action. The International Union for Conservation of Nature (IUCN) announced on Wednesday that key states where poaching takes place have promised to stop the ivory trade and protect Africa’s elephants.
In the 1980s, as many as 1 million elephants across Africa were killed for their ivory tusks. This continued until 1989, when the Convention on International Trade in Species (CITES) voted to ban all trade in ivory. With trade choked off, demand for ivory fell. Elephant populations slowly began to increase. However, this progress was short-lived.
According to the IUCN, 2011 saw the highest levels of poaching and illegal ivory trading in at least 16 years. Around 25,000 elephants were killed in Africa that year. Preliminary data from the IUCN shows even higher levels of illegal trade may have been reached in 2013. “With about 22,000 elephants illegally killed in 2012, we continue to face a critical situation,” said John E. Scanlon, CITES Secretary-General. “Current elephant poaching in Africa remains far too high, and could soon lead to local extinctions if the present killing rate continues.”
At the African Elephant Summit, key African states where elephants make their home agreed to develop a “zero-tolerance attitude” towards poaching. The deal calls for maximum sentences for poachers and hunters, and increased cooperation between affected states. Officials are determined to classifying wildlife trading as a serious crime — and to making sure that the people who commit it are punished. All participants at the conference agreed to sign the deal. With these states coming together, there may yet be hope for elephants. (293 words)
小題1:What’s the best title for this passage?
A．New Hope for Elephants.B． Elephants are dying.
C．Elephants are valuable.D． How to protect elephants
小題2:The underlined phrase “choked off” in Paragraph 2 can be replaced by “________”.
A． appreciatedB． preventedC． admittedD． explored
小題3:Which of the following statements is NOT true according to the passage?
A．The CITES has helped to improve elephants’ situation ever since 1989.
B．Around one million elephants across Africa were killed for their ivory tusks in the 1980s.
C．The poaching and illegal ivory trading in 2011 were very serious.
D．The situation of elephants in 2012 was still terrible.
小題4: All of the following measures will be taken to protect elephants EXCEPT ________.
A．to identify wildlife trading a serious crime
B．to punish those who buy or sell wildlife belongings
C．to sentence all wildlife poachers and hunters to death
D．to work together to fight against wildlife hunting
小題5:What’s the main idea of this passage?
A．The illegal ivory trade has been a major problem in Africa.
B．Elephants in Africa may die out because of the illegal poaching.
C．Hunting elephants will be recognized as a very serious crime.
D．A new agreement aims to develop a “zero-tolerance attitude” towards poaching.

Cultural Center Adds Classes for Young Adults
The Allendale Cultural Center has expanded its arts program to include classes for young adults. Director Leah Martin announced Monday that beginning in September, three new classes will be offered to the Allendale community. The course titles will be Yoga for Teenagers; Hip Hop Dance: Learning the Latest Moves; and Creative Journaling for Teens: Discovering the Writer Within. The latter course will not be held at the Allendale Cultural Center but instead will meet at the Allendale Public Library.
Staff member Tricia Cousins will teach the yoga and hip hop classes. Ms. Cousins is an accomplished choreographer (舞蹈教師) as well as an experienced dance educator. She has an MA in dance education from Teachers College, Columbia University, where she wrote a thesis on the pedagogical (教學法的) effectiveness of dance education. The journaling class will be taught by Betsy Milford. Ms. Milford is the head librarian at the Allendale Public Library as well as a columnist for the professional journal Library Focus.
The courses are part of the Allendale Cultural Center’s Project Teen, which was initiated by Leah Martin, Director of the Cultural Center. According to Martin, this project is a direct result of her efforts to make the center a more essential part of the Allendale community. Over the last several years, the number of people who have visited the cultural center for classes or events has steadily declined. Project Teen is primarily funded by a generous grant from The McGee Arts Foundation, an organization devoted to bringing arts programs to young adults. Martin oversees the Project Teen board, which consists of five board members. Two board members are students at Allendale’s Brookdale High School; the other three are adults with backgrounds in education and the arts.
The creative journaling class will be cosponsored by Brookdale High School, and students who complete the class will be given the opportunity to publish one of their journal entries in Pulse, Brookdale’s student literary magazine. Students who complete the hip hop class will be eligible to participate in the Allendale Review, an annual concert sponsored by the cultural center that features local actors, musicians, and dancers. All classes are scheduled to begin immediately following school dismissal, and transportation will be available from Brookdale High School to the Allendale Cultural Center and the Allendale Public Library. For more information about Project Teen, contact the cultural center’s programming office at 988-0099 or drop by the office after June 1 to pick up a fall course catalog.

"Gangnam Style" by singer Psy from Korea, is a popular song, but its extraordinary global success is really the result of its music video, which is a great piece of genius. On September 22nd, Guinness World Records listed "Gangnam Style" as the most-liked video in the history of YouTube. It's been performed at West Point (West-Point Style), and Google's CEO, has done the "Gangnam Style" horse dance at the company's office in Seoul. Even Samsung is trying to make Psy the new model for the latest type of fridge.
The song's global popularity is such that the vast majority of people who enjoy it don't speak Korean, and have no idea what it is about. That's fine --- part of what makes "Gangnam Style" so fun is, like international pop music, the difficulty in understanding it. When we sing along, "Hey, sexy lady", we don't really know what we're singing about.
The joy of incomprehensibleness is familiar to anyone who loves pop music from elsewhere. Anthony Lane, in his 2010 review of the Eurovision Song Contest, Only Mr. God Knows Why, used "Eurovision English" as one of its chief pleasures. It's "a complex tongue, spoken nowhere else, which raises the heartfelt poetry (詩意) but absolute nonsense to a level of what sci-fi writers could only have dreamed. " In similar ways, "Gangnam Style" is just an over-the-top video where a fat man does a funny dance and sings repetitive words that don't make sense to most of us.
But on the other, the magic of the song also lies in its funny dance, which reflects not just cultural morals specific to Korea, but cultural values easily recognizable to western viewers. This song's words may be in Korean, but its scenes are in clear American. The dance moves are simple enough to copy.
Nonsense, in other words, forces us to let down our guards. It makes us relax, and asks us to let in all sorts of feelings from which, otherwise, we might distance ourselves. "Gangnam Style" happens to be so interesting because of its incomprehensibleness.
小題1:Some complex languages are used in pop music because _______.
A．singers regard it as one of the chief pleasures at the concert
B．they make the music hard to understand but poetic and attractive
C．the music can sound more pleasant and beautiful to the audience
D．people like listening to the music which makes special sense to them
小題2:What is true about the popularity of "Gangnam Style"?
A．It was considered as the most popular video on the Internet.
B．It makes people amused and removes their emotional guards.
C．Its dance only reflects cultural and morals specific to Korea.
D．Psy, its singer, has been the new model for Samsung .
小題3:What does the underlined word "incomprehensibleness" mean in Paragraph 3?
A．Being interesting to listen to.B．Being simple enough to copy.
C．Being complex and repetitive.D．Being difficult to understand.
小題4:The text is mainly about ________.
A．how "Gangnam Style" becomes popular among the youths
B．why "Gangnam Style" is popular even if few people understand it
C．how Psy gains worldwide success through his talent and hard work
D．what emotions and cultural morals Psy wants to convey with his song

Chinese media and Internet users on Monday condemned(譴責) a lack of morals in society after a toddler(學步的小孩)was struck twice by two different vans and left bleeding on the road as more than a dozen bystanders did nothing to help the seriously injured girl.
The incident, captured by a surveillance camera and aired by Southern Television Guangdong (TVS), showed the two-year-old girl was knocked down and run over by a white van on a narrow market street on the afternoon of Oct. 13, in Foshan City of Guangdong Province.
The driver fled the scene of the accident, leaving the girl to bleed on the sidewalk. Over the next six minutes, more than a dozen people walked by the girl, yet not one individual did anything to help her. The girl was then hit a second time by another van before an elderly trash collector came to her aid and brought the attention of the girl’s mother, according to the video and eyewitnesses.
Doctors said that the girl, who was put on life support after being hospitalized, remains in a deep coma. The girl’s parents, who are migrants living in the city, are now with her. Police said the drivers of both vehicles have been arrested. However, the indifference of the bystanders shown in the video has shocked the public, as Internet forums have boiled with anger, and people are questioning the morality of society.
High moral standards were once triumphed as national pride in China where individuals known for selflessly helping others were adored by the public. But in recent years, the perception of a decline of morals has become a hot topic as profit and materialism are recognized to be affecting society’s values.
On Sept. 2. an 88-year-old man in central China collapsed, his face striking the pavement. Yet, no one came to his aid, and he ended up choking to death on the blood from his nose. Some have linked the absence of good models to a previous case in which a man trying to help an elderly woman who fell was accused of harming her.
A strong chorus of opinion on the Internet says laws should exempt（免除）models from responsibility, yet laws themselves cannot solve society’s morality dilemma.
Cao Lin, a China Youth Daily commentator, said in a signed article published on Monday that the worry of responsibility should not be an excuse for not helping, and this case exposes the decline of humanity in Chinese society.
小題1:What happened to the two-year-old girl?
A．Nobody helped her after she was struck by two different vans.
B．She died immediately after she was hit a second time.
C．An old trash collector saved her and attracted her mother’s attention.
D．Journalists from TVS captured her story by using a camera.
小題2:From the passage, what would happen if someone helped others selflessly in the past?
A．The public would feel proud of him/ her and showed love and respect for him/ her.
B．He/she would be awarded by the government.
C．He/she would be condemned by the public.
D．He/she would have to worry about legal responsibility.
小題3:In recent years, society’s values are believed to be affected by________.
A．people’s awareness
B．the indifference of bystanders
C．profit and materialism
D．the morals of society
小題4:According to Cao Lin, what is the fundamental reason for not helping the girl?
A．The worry of responsibility.
B．Lack of laws that exempt role models from responsibility.
C．The fear of being accused of harming her.
D．The decline of humanity in society.
小題5:Where is the article probably taken from?
A．A news report. B．A fashion magazine.
C．A science fiction.D．An education column.

A public high school in the rural town of Boonsboro，Maryland，offers a special program recently. Top students in the ninth and tenth grades can attend single－sex classes for math，science，English and social studies.
The aim is to help teenagers keep their mind on their work by keeping males and females apart. Rebecca Brown chooses the students for what Boonsboro High School calls the Academy. “What we really want to do is take that top group of kids and take them to the very highest level they can achieve here，so that they’re prepared for college，” she said. They need high marks and test scores and strong teacher recommendations. They also need to be involved in activities.
Michael Bair has been at Boonsboro High School for twenty years and directs the Academy. His ninth－grade English class for boys centers on books that he believes boys find interesting. “The novels they’re reading now，are very manly novels. They’re novels that deal with the arrogance(傲慢)of man and the pride of man.” One of those books，for example，is “The Call of the Wild” by Jack London. This classic story tells of a dog stolen from his home and sold to work as a sled dog in Canada’s Klondike Gold Rush.
On this day，the students are working in small groups. Vincent and Logan explain why they’re drawing pictures that relate to the story. Vincent said，“The main character，Buck，gets abducted(綁架),? and they send him off to the Yukon in a train. So I’m drawing part of the story where he’s in the train. It gets you to visualize the setting of the story and gets you to think more about what’s going on in the story，the important events of the story.”“ Instead of just doing work sheets about it，this is a lot more fun，” Logan added happily.
Morgan Van Fleet likes being in the Academy. She says boys and girls act differently when they are together in a classroom. “To me，it almost seems like it’s hindering(妨礙)? your chances at developing yourself because you’re more focused on ‘Oh，I wish they’d shut up. Oh，what do they think of me？’ instead of focusing on what’s the homework or what’s going on in this class，what’s the lesson.”
小題1:What is the purpose of the text?
A．To educate.B．To persuade.C．To instruct.D．To introduce.
小題2:In Rebecca Brown’s opinion，________.
A．any student in Boonsboro High School can take part in the program
B．students in the program are expected to get well prepared for college
C．students can all achieve their highest levels in the program
D．students don’t have to join in the activities.
小題3:The underlined word “visualize” in Paragraph 4 probably means “________”．
A．form a picture ofB．pay a visit to
C．take a look atD．have a gift for
小題4:What can we conclude from the text?____________.
A．Michael Bair considers it unsuitable for boys to read the book “The Call of the Wild”．
B．Vincent thinks that his drawings can help understand the novel better.
C．Jack London is a main character in the book “The Call of the Wild”．
D．Morgan Van Fleet thinks the program does no good to her.
小題5:The text is probably taken from________.
A．a school’s introductionB．a teacher’s diary
C．a headmaster’s speechD．a news report
