New York: when the first jet struck, World Trade Center at 8:48 am on Tuesday, the People in 2 World Trade Center with a view of the instant damage across the divide had the clearest sense of what they, too, must do: get out fast.
Katherine Hachinski, who had been knocked off her chair by the blast of heat exploding from the neighboring tower, was one of those. Despite her 70 years of age, Ms Hachinski, an architect working on the 91st floor of 2 World Trade Centre, the south tower, went for the stairs. Twelve floors above her, Judy Wein, an executive (經(jīng)理), screamed and set off too.
But others up and down the 110 floors, many without clear views of the damage across the way and thus unclear about what was happening, were not so sure. And the 18 minutes before the next plane would hit were ticking off.
Amid the uncertainty about what was the best thing to do, formal announcements inside the sound tower instructed people to stay put, assuring them that the building was sound and the threat was limited to the other tower.
Some left, others stayed. Some began to climb down and, when met with more announcements and other cautions(警告) to stop or return, went hack up. The decisions made in those instants proved to be of great importance, because many who chose to stay were doomed(注定死亡) when the second jet crashed into the south tower, killing many and stranding(使某物留在) many more in the floors above where the jet hit.
One of those caught in indecision was the executive at Fuji Bank UAS.
Richard Jacobs of Fuji Bank left the 79th floor with the other office workers, but on the 48th floor they heard the announcement that the situation was under control. Several got in the lifts and went back up, two minutes or so before the plane crashed-into their floor.
“I just don’t know what happened to them,” Mr. Jacobs said.
1. From the passage, we know that the south tower was hit by the plane_______.
A. at 8: 30                   
B. 18 minutes earlier than the north tower
C. at around 9:06
D. at 8:48
2. The underlined words “stay put” means_______.
A. stay in the building                        B. leave at once
C. put everything back and then leave   D. keep silent
3. Which floor was hit by the second jet?
A. the 91st floor                                 B. the 103rd floor
C. the 60th floor                                D. the 79th floor
4. Fewer people would have died if_______.
A. more announcement had been made
B. people hadn’t used the lifts
C. the incident had happened on a weekend
D. the people had obeyed the office rules

The unimaginable earthquake in Haiti has shocked the world. Thanks to modern communication technology, the world has seen the scale of destruction by the 7.0- magnitude quake. Images on TV and the Internet show the Haiti capital has been reduced to rubble and helpless survivors waiting for relief.
So far, at least 50,000 people are feared dead, and tens of thousands left injured or homeless in one of the poorest countries in the West. The number of dead is rising with each passing hour for a few days. Considering Haiti’s total population is only about 8.5 million, the extent of damage will reach every field of the country’s social structures.
Rescuers from countries such as China, the United States, France and Dominican Republic have already reached Haiti, carrying necessary things like food and medicines, life-detecting devices and other rescue equipment. Politicians，workers and Hollywood actors have opened their wallets and called for donations to help disaster relief. The whole world is ready to help them. The world is a village today where no one can remain indifferent when a neighbor falls in disaster.
The suffering of people anywhere in the world strikes the hearts of Chinese people. The death of eight Chinese peacekeepers in Haiti has little to do with it. Chinese people feel a special sympathy for Haitians because just less than 20 months ago they were struggling to rise from the earthquake.
Though Beijing and Port-au-Prince have no diplomatic relations, China was among the first nations to send a rescue team and to announce a donation. In the face of natural disasters, respect for human lives overtakes diplomacy and national boundaries. We share the pain of the Haitian people, and we believe China’s experience in rescue and operations and reconstructions will help reduce that pain.
The most pressing task after a quake is the golden-hour rescue operation. Many Haitians are buried under rubble, and relentless efforts must be made to save as many of them as possible. Yet there remains a question on how effectively the flows of aid from around the world be managed. It is here that the UN can play the leading role, for it should be responsible for common humanitarian efforts from across the globe to reach the benefits to the maximum number of people.
After the 2004 tsunami killed more than 200,000 people in Asia, some experts said the UN needed to build a well-equipped and trained force disaster rescue specialists and keep it on standby to help people after natural disasters such as the Haiti quake. It is time the UN gave the idea a serious thought, for a life-saving force could play as important as its peacekeeping soldiers.
60.According to the passage, which of the following is true?
A.The number of Haiti’s total population is about 8.5 billion
B.Rescuers from many countries have reached Haiti, carrying necessary things like food, water and medicines.
C.Chinese people feel a special sympathy for Haitians because we have the same experiences.
D.The flows of aid from the world has been managed well.
61.The word “indifferent” underlined in the third paragraph most probably means ______.
A.cruel         B.friendly        C.cold         D.warm
62. We can infer that people around the world actively help the Haitians because ______.
A.people among countries have close relations
B.earthquake is a natural disaster, people respect human lives, and show common feelings to people in trouble
C.people should be responsible
D.people have ever been rescued by Haitians
63.Which of the following would be the best title for the text?
A.The UN plays an important role
B.We are with you, Haiti
C.People share the pain with the Haitian people
D.Modern communication technology is used widely

WASHINGTON(Reuters)-People who drink two or more sweetened soft drinks a week have a much higher risk of pancreatic cancer(胰腺癌)，an unusual but deadly cancer，researchers reported on Monday．
People who drank mostly fruit juice instead of sodas did not have the same risk，the study
of 60,000 people in Singapore found．
Sugar may be to blame but people who drink sweetened sodas regularly often have other
poor health habits，said Mark Pereira of the University of Minnesota，who led the study．
“The high levels of sugar in soft drinks may be increasing the level of insulin(胰島素)in The body,which we think contributes to pancreatic cancer cell growth,”Pereira said in a statement．
Writing in the joumal Cancer Epidemiology，Biomarkers & Prevention，Pereira and colleagues
said they followed 60,524 men and women in the Singapore Chinese Health Study for l4 years．
Over that time，140 of the volunteers developed pancreatic cancer．Those who drank two or
more sweetened soft drinks a week had an 87 percent higher risk of being among those who got
pancreatic cancer．
Pereira said he believed the fndings would apply elsewhere。
“Singapore is a wcahhy country with excellent heahhcare．Favorite pastimes(消遣)are
eating and shopping，so the findings should apply to other western countries，”he said．
But Susan Mayne of the Yale Cancer Center at Yale University in Connecticut was cautious．
“Although this study found a risk，the finding was based on a relatively small number of
cases and it remains unclear whether it is a causal(因果的)connection or not。”said Mayne．
who serves on the board of the journal，which is published by the American Association for
Cancer Research．
Pancreatic cancer is one of the deadliest forms of cancer，with 230,000 cases globally．In

To swim across the English Channel takes at least nine hours. It‘s hard work and it makes you short of breath. To fly over the channel takes only twenty minutes as long as you’re not held up at the airport， but it‘s an expensive way to travel. You can travel by hovercraft （氣墊船）if you don’t mind the noise and that takes forty minutes. Otherwise， you can go by boat， if you remember your sea-sickness pills. All these means of transport have their problems， and the weary（厭煩的）traveler often dreams of being able to drive to France in his own car. “Not possible， you say. Well， wait a minute. People are once again considering the idea of a channel tunnel or bridge.” This time， the great London Council（議會）is looking into the possibility of building a channel link straight to London. A bridge would cost far more than a tunnel， but you would be able to make a journey by rail or by car on a bridge， yet a tunnel would provide a rail link only. Why is this idea being discussed again？ Is Britain realizing the need for links with Europe as a result of joining EEC？Well， perhaps， the main reason， though， is that a tunnel or bridge would reach the twenty square kilometers of London‘s discussed dockland（船塢）。 A link from London to the continent would stimulate（刺激） trade and revitalize（使重新具有活力）the port， and would make London a main trading center in Europe. With a link over the Channel， you could buy your fish and chips in England and be able to eat them in France while they are still warm！
小題1:From the lines we can see that people crossed the Channel by ______ in the past.
A．a(chǎn)irB．boatC．swimmingD．A， B， or C
小題2:The weary traveler thinks the best way to cross the Channel is ______.

BEIJING, March 1 (Xinhua)-China's top economic planning body has confirmed the government will take concrete actions to develop a low-carbon economy after it promised to considerably reduce carbon emission (排放) at  last year's Copenhagen Climate Conference.
China would include the low-carbon targets in the 12th five-year plan for national economic development (2011-2015) to build an energy-saving, ecologically friendly society, the National Development and Reform Commission (NDRC) said in a report to the Standing Committee of the 11th National People's Congress (NPC).
The report said the government would launch a series of technological and financial support policies to promote the use of non-fossil, renewable energies including wind, solar, biomass, geothermal (地?zé)? and nuclear power, aiming to increase its percentage of primary energy consumption to about 15 percent by 2020 from 9.9 percent at the end of last year.
China's installed wind power capacity (容量) reached 15 million kilowatts, with 10 million kilowatts under construction at the end of June 2009, while nuclear power under construction, installed hydro-electric power capacity and solar heating collection areas were the highest in the world, it said.
The commission was also planning to make a catalog (目錄) of emissions of greenhouse gases in an effort to build a monitoring and checking system to cut carbon emissions.
The economic planner decided to control unnecessary construction and industries with surplus (多余的)production capacities, such as steel, cement and electrolytic aluminum, to promote the energy efficiency and environmental protection.
The government had drafted a plan on regional development to transfer industries in eastern areas to central and western regions.
The State Council announced in November that China would reduce the intensity of carbon dioxide emissions per unit of GDP in 2020 by 40 to 45 percent compared with the level of 2005.
67.Which of the following best summarizes the low-carbon economy China is to develop?
A.Energy-saving and ecologically friendly.
B.Promoting the use of clean energy.
C.Developing the industry in the wild west.
D.Reducing carbon emissions per unit of GDP by 40 to 50 percent.
68.Which of the following does NOT belong to China's low-carbon measures mentioned in the text?
A.Limiting the use of nuclear power and other primary energy.
B.Setting up a system to monitor and check carbon emission.
C.Controlling unnecessary construction and industries with extra production capacities.
D.Planning to move industries from eastern areas to central and western regions.
69.If you are planning to start your own business in line with the low-carbon economy, which is the best choice?
A. An iron and steel plant.     B. A petrochemical works.
C. A solar heating company.  D. A construction company.
70.The passage is mainly about     .
A. China's plan of economy development in the 12th five-year plan
B. China's efforts to build up a low-carbon economy
C. NDRC's reaction to Copenhagen Climate Conference
D. NDRC's plan handed over to the Standing committee of 11th NPC

Chinese reports say the country’s vast pool of cheap labor is getting smaller, which could hurt an economy that heavily depends on labor-intensive manufacturing.
The academy’s research shows that China’s rural labor surplus, the source of migrant workers for the country’s factories, is about 50 million people—far less than the previously estimated 150 to 200 million.
Jonathan Unger, director of the Contemporary China Center at the Australian National University, says fewer rural residents are willing to leave their farms today. This is partly because there are more employment opportunities in rural areas, and because agricultural prices have gone up.
“And at the same time taxes in the countryside, fees in the countryside have gone down because of new sets of government policies,” he explained. “So people are not eagerly forced in the way they were five, six years ago to leave the farm in order to earn enough money for their families.”
The Chinese Academy of Social Sciences says another reason for the reduced labor pool is the country’s population policy, which allows city residents to have just one child, and farmers up to two if the first one is a girl.
A UN study predicts that China’s workforce will reach its top in 2015 and then gradually drop. Some of China’s major manufacturing areas, such as Guangdong Province, already face labor shortages.
Some economists think these shortages are, at least for now, a regional rather than a national problem. Sun Mingchun, an economist with investment bank Lehman Brothers in Hong Kong, points out that there are still millions of people in China who can not find work.
57. According to the academy’s research, China’ rural labor surplus today is about _______.
A. 150 million      B. 50 million      C. 200 million      D. 175 million
58. The reason why many rural residents don’t leave their farms today is ________.
A. the farmers are older than before.
B. the farmers are lazier than before
C. the farmers have much more money
D. there are more employment opportunities and agricultural prices have gone up
59. Which of the following is TURE according to the passage?
A. A study of UN estimates China’s workforce will come to the top in 2015.
B. No a study shows millions of people can’t find work in China.
C. The country’s population policy isn’t a reason for the reduced labor.
D. Five years ago, few farmers left their homes to earn money for supporting their families.
60. According to some economists, the shortage of Chinese workforce __________.
A. is a national problem                     B. is a regional problem
C. is not a problem                         D. can be solved easily

WASHINGTON – It’s a great achievement that inspires notions of robots with consciousness and independent minds.
When people or animals get hurt, they can usually compensate for minor injuries and keep limping along, but for robots, even slight damage can make them stumble and fall. However, a recently made robot has demonstrated a novel ability: it can heal its own damage.
The new robot, which looks like a splay – legged, four – footed starfish can sense injury to itself and adapt. That ability sets the new robot apart from earlier machines. Because the robot can recover from unfamiliar places. “There is a need for planetary robotic rovers to be able to fix things on their own,” says Josh Bongard, a professor in the University of Vermont, who is one of the device’s creator. “Robots on other planets must be able to continue their mission without human help if they are damaged and cannot communicate their problem back to Earth.”
A typical robot functions according to a computer program, but the new robot works differently. First, sensors in its four legs observe the robot’s movements and signals to its built – in computer. From the formation it collects, the robot creates its own programs that allow it to adapt to different situations. For example, when the researchers shortened one of the robot’s legs, the smart machine simply adjusted its way of walking – it used three legs instead of four.
The researchers are looking for other places to put the resilient robot to work. One pellicle spot is the ocean floor. That dark and dangerous undersea terrain might be a good choice for a robot the scientists call the Starfish. “We never officially named the robot, but we usually refer to it as the Starfish, even though a real starfish has five rather than four legs,” says Bongard. “Also, a real starfish  is much better than our robot at recovering from injury, because it can actually grow its legs again.” Scientists have created robots that help humans in many ways: by exploring space, fighting fires, and even performing surgery.
46．The newly designed robot distinguishes itself from the former ones because it___________
A．can communicate with people on the earth about their problems
B．works according to a certain computer program
C．can find its problems and solve them automatically
D．can explore unfamiliar places
47．An example is given in the fourth paragraph in order to explain that the robot ___________
A．is used to create new programs
B．has typical robot functions
C．has sensors to observe its movements
D．can gather information and adapt to new conditions
48．The underlined word “resilient” in the last paragraph means the robot is ___________.
A．creative    B．newly made     C．a(chǎn)ble to recover    D．informative
49．Which of the following is TURE about the robot “Starfish”?
A．It was spoken highly of by people for its special ability?
B．It will stumble and fall if damaged.
C．It can grow its legs again once they are broken.
D．It has started to work on the ocean floor.
50．What might be the best title of the passage?
A．How does the Starfish Robot work
B．Do – It – Yourself Robot Repair
C．Robots Designed to Work On Other Planets
D．New Robot Helping Us In Many Ways
