Professor Rongjia Tao of Temple University, Philadelphia unveiled a proposal this week calling for the construction of three 1,000-foot barriers up to 100 miles long, which would act like hill ranges and soften winds before tornadoes could form, the BBC reports.
The $16.9 billion plan would call for the faux hill ranges in North Dakota, along the border between Kansas and Oklahoma, and in Texas and Louisiana, ostensibly saving billions of dollars in damage every year, Tao said. The walls would not shelter towns, he said, but instead would soften the streams of hot southern and cold northern air that form tornadoes when they clash in the first place.
But critics laughed at Tao’s proposals. Leading tornado experts pointed to areas that are already protected by hill ranges the size of the barriers Tao is proposing, yet still have plenty of tornados, like parts of Oklahoma, Arkansas and Missouri. And even if the plan did work, it would create more problems than it would solve, scientists said, by creating catastrophic weather side effects.
“Everybody I know is of 100% agreement – this is a poorly conceived idea,” Professor Joshua Wurman of the Center for Severe Weather Research. “From what I can gather his concept of how tornadoes form is fundamentally flawed（有缺陷的）. Meteorologists（气象学家） cringe（尴尬） when they hear about ‘clashing（交锋） hot and cold air’. It’s a lot more complicated than that.”
小题1:What does the underlined word “unveiled”mean in the fourth paragraph？
| A．reminded | B．came up with | C．referred | D．applied |
| A．The different opinions on the proposal that the walls will reduce the loss caused by tornadoes. |
| B．How to solve the problems that are caused by tornadoes. |
| C．The proposal mentioned in the paragragh is totally wrong. |
| D．The proposal to reduce tornadoes is effective. |
| A．the tornadoes form by clashing（交锋） hot and cold air. |
| B．if the walls are built, they will work well. |
| C．if the plan is carried out, we will have more problems than expected. |
| D．The walls not only soften the winds but also shelter the towns. |
| A．Leading tornado experts think that would soften the streams of hot southern and cold northern air that form tornadoes. |
| B．Professor Joshua Wurman pointed out that the plan will be expensive. |
| C．Professor Rongjia Tao is against the construction of walls to prevent the tornadoes. |
| D．the plan will not be carried out because it will creating serious weather side effects. |

The 48-year-old policeman intervened to stop the butchering of unarmed civilians, saving many from death and injury, but he was injured in the process.
Lying in a hospital bed, his head and nose marked by serious hacking wounds - one more than 20 centimeters long - Xie recounted（详细叙述） his actions on the day he describes as a nightmare.
"I shot at them but fell to the ground during the fighting. After the shots, the terrorists turned their attention to the police and several of them surrounded me and stabbed me like crazy," he said. "There is no humanity in them."
Xie is from the Beijinglu Police Station, the closest to the attack, and four police officers from the station were the first to respond. He survived because he was wearing a bulletproof vest, which was damaged by the attackers.
When the officers arrived, the attackers were running out of the ticket hall, attacking people with long knives.
Xie and his colleagues tried to stop the attack, which is when Xie was injured. In addition to the deep cuts, his skull was fractured, and at the time of writing he was awaiting further surgery.
"A wave of fierce anger rose up in my mind, and we all forgot to think about the possible danger to us," said Hu Zhe, 23, a police officer trainee at the Beijinglu Police Station.
Having no firearm, he fought the terrorists with a wooden baton, but it got broken in the fighting. He sustained a 6-centimeter wound to his left eyebrow.
Wan Weiqing, a neurosurgeon from Beijing Tiantan Hospital, learned of the attack at 2 am on Sunday and took the first flight to Kunming, where he has been helping the victims.
He said that 71 victims are being treated at the Kunming First People"s Hospital, most of them with severe multiple injuries.
"There is one victim whose rib, breastbone, lung and even heart were all injured in one chopping action. The attackers had obviously prepared and practiced for a long time," he said.
Zhou Hongmei, director of the Medical Reform Office at the Yunnan Health Department, said a team of medical experts including 29 doctors had arrived in Kunming by Monday night. They have been working at the five hospitals treating victims of the attack.
Chen Min, a Neurology Department nurse at Kunming First People"s Hospital, said the department usually had seven nurses in the daytime and three at night. "But all the other nurses who were not on duty returned to the hospital voluntarily on Saturday night," she said.
In the past three days, none of them had more than 10 hours of rest.
"The crucial factor in saving lives in such incidents is treatment without delay," said Chai Wenzhao, associate director of the Intensive Care Unit in the Peking Union Medical College Hospital. Chai has participated in many emergency rescue efforts.
He said that the victims will need psychological counseling once their physical injuries have been dealt with, because the emotional impact of such an incident can be severe.
Four psychologists from Anding Hospital in Beijing have begun treating some of the victims.

A trip to see painter Jacob Lawrence’s Migration Series is one of almost 200 trips that Wheelock will organize this year through the nonprofit group Live It Learn It. “For many kids, school is disconnected,” says one of four full-time workers and tour leaders. “With the program, they see how what they are learning is connected to their communities.”
Seven years ago, Wheelock changed a job as a lawyer for one as a four-grade teacher. When he learned that D.C.’s public schools ranked behind those of other cities in many ways, he knew he had to do something different. He took his class to Capitol Hill for a lesson on the three branches of government — and saw his students’ interest develop quickly.
With seed money from a local couple, Wheelock developed detailed lesson plans for trips to the U.S. Holocaust Memorial Museum, the Lincoln Memorial. The group also has classes for trips to the Anacostia River, boat rides to historical forts. Word spread, and now fourth, fifth, sixth graders from the neediest public schools in the District participate.
“I’m not brave enough to take my class to a museum for over an hour!” says teacher Cathy McCoy, gesturing toward her students. “But look With Live It Learn It, what the kids learn today they’ll remember for a lifetime.”
小题1:Matthew Wheelock once had an occupation as a _______.
| A．teacher | B．printer | C．leader | D．lawyer |
A. like to have school disconnected
B. are warmly welcomed by museums and monuments
C. are making the resources at hand available
D. are learning by going to different communities
小题3:Matthew Wheelock started the new change for the reason that _______.
A. he saw his students’ interest develop quickly
B. more graders from the neediest public schools wanted to participate
C. D.C.’s public schools ranked behind in many ways
D. a local couple sponsored him a sum of seed money
小题4:What will the lessons be like with Live It Learn It in Cathy McCoy’s opinion?
| A．Eye-catching. | B．Challenging. | C．Forgettable. | D．Impressive. |
Previous Olympic hosts have been criticized for the environmental damage they have caused through construction, waste and transport．But things had to be different in London．
What is most impressive is that London considered the construction of the Olympic Park as an opportunity to clean up polluted areas．2 million tons of polluted soils were removed and 200 old factory buildings were torn down, according to sustainablebusiness．com．But that’s not all．99 percent of the debris（废瓦砾）were reused to build the Olympic Park．
As well as using recycled materials, all gymnasiums were built with green building techniques．The Olympic Stadium is the lightest one ever built, which minimized the amount of steel and concrete needed．Also, the handball field has lighting pipes on the roof that reduce electricity use by 40 percent．
The effort that London made to deal with waste also deserves praise．Water used for drinking and watering plants was from collected rainwater or recycled wastewater．In this way, about 30-40 percent less water was used in total．Waste food package were either recycled or processed and turned into renewable energy．
As one of the best connected places in Europe, London tried to solve traffic jams by encouraging the use of public transport．For example, it had trains deliver half of the building materials, instead of cars, which greatly reduced carbon emissions（排放）．
The clean anti-doping result also added to the greenness of the Games．Only one athlete tested positive for a banned drug on the day of competing, which is why the IOC President, Jacques Rogge, has praised anti-doping efforts at the London Games．
小题1:To make the Olympic Park green, London ________．
| A．recycled 2 million tons of polluted soil |
| B．applied green building techniques to the construction |
| C．built the Olympic Stadium mostly with recycled materials |
| D．removed 99 percent of the debris from the city |
| A．increased as much as possible | B．made use of |
| C．reduced as much as possible | D．took little notice of |
| A．The London Olympics cost less than the other Olympics ever held． |
| B．London has possessed the most advanced techniques to deal with waste． |
| C．Public transport is made good use of in London during the Olympic Games． |
| D．The anti-doping result in the London Olympics turned out to be dissatisfactory． |
| A．The effort that London made to deal with waste isn"t worthy of praise． |
| B．In terms of holding the greenest Games, the London Olympics was a success． |
| C．London tried to solve traffic jams by encouraging the use of private cars for free． |
| D．The IOC President, Jacques Rogge was unsatisfied with the anti-doping efforts at the London Games． |
What’s causing the puffin trouble? Scientists think it may be a shortage of food. With ocean temperatures rising, fish populations have moved around. Normally, puffins’ primary food source is herring, a type of fish. A lack of herring in the area could be causing the problem.
Butterfish from the south have become more abundant in the Gulf of Maine and could be a new food source for birds. But Steve Kress says butterfish may be too big and round for baby puffins to swallow.
Puffins spend most of their lives at sea. They come ashore to breed each spring and return to the ocean in August. The chicks swim to sea about 40 days after hatching. Puffin populations stretch across the North Atlantic, from Maine to northern Russia.
Maine’s puffin population has been at risk in the past. In the 1800s, they were hunted for their food, eggs and feathers. By 1901, only one pair of puffins remained in the state. Thanks to the help of local lighthouse keepers and seabird restoration programs, the state’s puffin population has been restored to more than 2,000 birds.
Scientists aren’t sure what will happen to the Gulf of Maine’s puffins. The birds may move further north. Kress says he hopes the Gulf population will sustain itself and then he continued. “You never know what climate change will bring,” Kress said. “Historically fish could move out and more southerly fish could move in, and puffins may adapt to the new fish. Only they will know how the story will unfold.”
小题1:The underlined phrase “took a dive” means _______.
| A．increased | B．arose | C．reduced | D．changed |
| A．a lack of herring | B．environmental pollution |
| C．the increase of birds | D．the huge size of butterfish |
| A．Maine’s puffin once nearly became extinct |
| B．Maine’s puffins’ eggs were of high prices |
| C．baby puffins grew up quickly |
| D．the number of Maine’s puffins is worrying |
| A．climate change matters little |
| B．there is cause for concern |
| C．the new fish won’t harm puffins |
| D．puffins may move to the south |
| A．By giving examples. | B．By making comparisons. |
| C．By following time order. | D．By asking questions |
“Your current requirement that all archaeologically unearthed human remains should be reburied, whether after a standard period of two years or further special extension, is contrary to basic principles of archaeological and scientific research and of museum practice,” they write.
The law applies to any pieces of bone uncovered at around 400 dig sites, including the remains of 60 or so bodies found at Stonehenge in 2008 that date back to 3,000 BC. Archaeologists have been granted a temporary extension to give them more time, but eventually the bones will have to be returned to the ground.
The arrangements may result in the waste of future discoveries at sites such as Happisburgh in Norfolk, where digging is continuing after the discovery of stone tools made by early humans 950,000 years ago. If human remains were found at Happisburgh, they would be the oldest in northern Europe and the first indication of what this species was. Under the current practice of the law those remains would have to be reburied and effectively destroyed.
Before 2008, guidelines allowed for the proper preservation and study of bones of sufficient age and historical interest, while the Burial Act 1857 applied to more recent remains. The Ministry of Justice assured archaeologists two years ago that the law was temporary, but has so far failed to revise it.
Mike Parker Pearson, an archaeologist at Sheffield University, said: “Archaeologists have been extremely patient because we were led to believe the ministry was sorting out this problem, but we feel that we cannot wait any longer.”
The ministry has no guidelines on where or how remains should be reburied, or on what records should be kept.
小题1:According to the passage, scientists are unhappy with the law mainly because _______.
| A．it is only a temporary measure on the human remains |
| B．it is unreasonable and thus destructive to scientific research |
| C．it was introduced by the government without their knowledge |
| D．it is vague about where and how to rebury human remains |
| A．Temporary extension of two years will guarantee scientists enough time. |
| B．Human remains of the oldest species were dug out at Happisburgh. |
| C．Human remains will have to be reburied despite the extension of time. |
| D．Scientists have been warned that the law can hardly be changed. |
| A．The Ministry of Justice did not intend it to protect human remains. |
| B．The Burial Act 1857 only applied to remains uncovered before 1857. |
| C．The law on human remains hasn’t changed in recent decades. |
| D．The Ministry of Justice has not done enough about the law. |
| A．New discoveries should be reburied, the government demands. |
| B．Research time should be extended, scientists require. |
| C．Law on human remains needs thorough discussion, authorities say. |
| D．Law could bury ancient secrets for ever, archaeologists warn. |
