With only about 1, 000 pandas left in the world, China is desperately trying to clone(克隆) the animal and save the endangered species. That’s a move similar to what  Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”.
Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen(氮). If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated that as many as 2, 000 species of mammals, birds, reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
“The nuclear transfer(核子移植) of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog.
“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”
60. The aim of “Noah’s Ark” project is to _______.
A. make efforts to clone the endangered pandas 
B. save endangered animals from dying out
C. collect DNA of endangered animals to study
D. transfer the nuclear of one animal to another
61. According to Professor Kraemer, the major problem in cloning pandas would be the lack of _______.
A. available panda eggs                B. host animals
C. qualified researchers                D. enough money
62. The best title for the passage may be _______.
A. China’s Success in Pandas Cloning                       
B. The First Cloned Panda in the World
C. Exploring the Possibility to Clone Pandas  
D. China —the Native Place of Pandas Forever
63. From the passage we know that _______.
A. Kraemer and his team have succeeded in cloning a dog
B. scientists try to implant a panda’s egg into a rabbit
C. Kraemer will work with Chinese scientists in clone researches
D. about two thousand of species will probably die out in a century

Continuing from the previous post 6 reasons to improve your body language, here is just a few of many pointers on how to improve your body language. Improving your body language can make a big difference in your people skills, attractiveness and general mood.
There is no specific advice on how to use your body language. What you do might be interpreted in several ways, depending on the setting and who you are talking to. You’ll probably want to use your body language differently when talking to your boss compared to when you talk to a girl/guy you’re interested in. These are some common interpretations（解釋，詮釋） of body language and often more effective ways to communicate with your body.
First, to change your body language you must be aware of your body language. Notice how you sit, how you stand, how you use you hands and legs, what you do while talking to someone.
You might want to practice in front of a mirror. Yeah, it might seem silly but no one is watching you. This will give you good feedback on how you look to other people and give you an opportunity to practise a bit before going out into the world.
Another tip is to close your eyes and visualize how you would stand and sit to feel confident, open and relaxed or whatever you want to communicate. See yourself move like that version of yourself. Then try it out.You can also take bits and pieces you like from different people. Try using what you can learn from them.

The quality of drinking water in Shanghai will meet European Union standard by 2010 and, a decade later, citizens in Shanghai will drink the best water in the world.
These were the goals set out by the Shanghai Water Authority. With the city’s population expected to increase only slightly and the economy to boom by 2020, Chen Yin, and official with the water authority, said Shanghai’s water consumption will not increase from its present amount.
Zhang Yue, director of the Urban Construction Division under the Ministry of Construction, said, “Shanghai is the first city in the country to publicize these ambitions. They will not be easy to achieve.”
He said water saving will help keep the sustainable development of China’s economy.
Saving one cubic meter of water means saving the city’s infrastructure（基礎(chǔ)設(shè)施）costs by 10,000 Yuan. Last year, Shanghai saved 300 million cubic meters of water either from readjustment of industrial structure or the employment of new technology.
“The aim is to arouse public awareness of the seriousness of water shortages,” Chen said. “The abundant surface water and amount of rain of the city are so misleading that they result in improper use of water.”
Shanghai lacks drinkable water. The Huangpu River, which supplies 80 percent of the city’s drinkable water, is nearing exhaustion.
The city, therefore, has been exploring new sources from the Yangtze River and growing forests along it to conserve quality water.
Besides penning regulations, the authority is popularizing technology among the public to efficiently cut the amount of water used.
At present, the city has 600，000 family toilets, each using 13 liters of water per flush. These are to be renovated（整修）to use only 9 liters of water per flush.
The authority is renovating the first 200 toilets for households – at a cost of 40 Yuan each.
In three years, all the toilets will be renovated, which saves the city nearly 15 million Yuan every year in water conservation.
Another task the city is engaged in is the treatment of sewage（污水）to improve the water environment.
At present the city can only treat 44 percent of its daily 5.04 million tons of waste water. To meet the total demand, 27 more sewage treatment factories are to be established with an estimated investment of 18 billion Yuan.
41．People in Shanghai get their daily water mainly from _______now.
A．the underground                          B．the rain     
C．the Yangtze River                         D．the Huangpu River
42．According to the passage, some people have the wrong opinion of using water
because      .
A．the renovating of family toilets will save plenty of water
B．a(chǎn)bout half of waste water has been treated already
C．a(chǎn)dvanced technology makes people use water as much as possible
D．there is plenty surface water and large amount of rain at present
43．The authority is renovating the first 200 toilets for households to          .
A．make people’s living more convenient     
B．improve people’s living standards
C．ease employment pressure      
D．meet the total demand of water
44．Which group of measures are all mentioned in the passage to save water?
a．improve drinking water quality
b．change some industrial structure
c．introduce or use some new technology    
d．speed the economic development of Shanghai
e．renovate some family toilets    
f．build more sewage treatment factories
A．a(chǎn), b, c, d                       B．b, c, e, f                       
C．b, c, d, e              D．a(chǎn), b, e, f
45．We can infer from the passage that          .
A．the boom of economy will need a larger amount of water in the future
B．citizens today in Shanghai drink the best quality of water in the world
C．not everyone today in Shanghai is aware of water shortage
D．a(chǎn)ll the family toilets will be renovated to save water within 3 years

Another man-made wonder of the United States was built long before the nation was established. About 900 years ago, the Ancestral Puebloan people built villages high in the walls of canyons in Colorado, where 600 cliff dwellings are now part of the Mesa Verde National Park.     
Visitors can stand at the top of the mesas and look into the dwellings almost hidden in openings of the rock walls. The Puebloan people cut small steps into the rock, which connected buildings containing hundreds of rooms.
The rock walls have protected the buildings from severe weather in the area; therefore, they remain mostly unchanged in the hundreds of years since they were built.
Our final man-made wonder is in the northwestern city of Seattle, Washington. The Space Needle was built as the central structure for the 1962 World's Fair.           
The 184-meter-tall structure was designed by Edward Carlson, which has a wide base on the ground, with its middle narrow and a large ring-like structure on top. The structure was meant to look like a "flying saucer," a vehicle that was popular in science fiction space travel stories.  The saucer includes an observation area and eating place. The restaurant slowly turns to provide visitors with a 360 degree view of Seattle.
The Space Needle, only costing about $4,500,000, was not very costly, and was designed and completed in about a year and opened on the first day of the World's Fair.
Today, the Space Needle is the most popular place for visitors to Seattle. And it remains the internationally known symbol of the city.
56.What the passage before this one can be about?
A.Some natural wonders in the world.
B.Sightseeing in the US.
C.Some other artificial wonders in the US.
D.American geography.
57. What does the underlined word “dwelling” mean?
A. village                     B. house               C. canyon             D. step
58. Which of the following descriptions about the Space Needle is TRUE?
A. It is a man-made wonder in Washington, D.C..
B. Edward Carlson built the structure.
C. It has a ring-like structure on top.
D. It remains the internationally known symbol of the US.
59. What is the passage mainly about?
A. Visiting the US                B. Man-made wonders in the US
C. Wonders in the world              D. Famous places in the US

閱讀下列短文，從每題所給的四個選項(A、B、C和D)中，選出最佳選項。
Snakes bite an estimated 5.5 million people worldwide each year. Experts say tens of thousands of people die from venom poisoning. An untreated or incorrectly treated bite might require the removal of a bitten foot, for example, or an arm. Each year around 400,000 amputations are the result of snakebites.
Last year, for the first time, the World Health Organization added snakebites to its list of "neglected tropical diseases". This recognition aims to bring greater attention to the problem. Scientists know of about 3,000 kinds of snakes. About 600 of them are venomous. These are most often found in rural areas in tropical climates. Asia and Africa have the highest number of snakebites -- together about 4 million a year. Latin America and islands in the South Pacific follow.
The highest number of victims are agricultural workers. Snakebites are also common among fishermen, hunters and children. Many victims live in areas with poor or non-existent health care systems and where anti-venom treatments are often not available.
Anti-venom is the only cure. But experts say anti-venom technologies and their use need to be improved. Problems include a shortage of manufacturers and the high cost of treatment. Also, there is a widespread lack of knowledge among local health workers about how to use anti-venoms. The treatments can cause dangerous and even deadly reactions if not used carefully.
Anti-venom contains proteins (蛋白質(zhì)) from animals such as horses or sheep. The animals are injected repeatedly with one or more different snake venoms to produce immunity (免疫力). The Lancet Medical Journal recently published a series of reports on snakebite prevention and treatment, David Warrell at the University of Oxford in England co-wrote one of them. He praised efforts by the WHO to establish common practices for the production, regulation and control of anti-venom. But he says more must be done.
The authors say community education programs could help prevent snakebites by teaching people how to avoid them. They also suggest actions like providing protective boots to wear while working in fields, and not sleeping on the ground. Also important is providing information about where dangerous snakes are most likely to live and when they are most active.
56. What's the meaning of the underlined word "amputations" in Paragraph 1?
A. removals of one's arms or legs                       B. deaths caused by infection
C. injuries of snakebites                                D. fames of a celebrity
57. Why did WHO add snakebites to its list of "neglected tropical diseases"?
A. To warn people of the danger of snakes.        
B. To encourage people to protect wild animals.
C. To ask people to pay more attention to this kind of disease.
D. To study the problem of tropical weather conditions.
58. Which of the following is True according to the passage?
A. The victims wouldn’t be injured if they had better health-care systems.
B. Anti-venom technologies and their uses are medically safe and perfect.
C. Patients need to pay a little if they get treated with the anti-venoms.
D. The local health workers need further training on how to use anti-venoms.
59. The animals are injected with different snake venoms because _______.
A. they have been bitten by venomous snakes      B. venoms can help to cure their diseases
C. this can help produce the immunity                D. medical experiments are being carried out

Japan's 24-hour convenience stores, already struggling with lagging sales and growth, may soon face yet another threat - moves to limit business hours and close the stores late at night. The district of Saitama, which borders Tokyo, may follow in the footsteps of the western city of Kyoto and urge convenience stores to close during late night hours in an effort to limit carbon dioxide（二氧化碳）emissions, Japanese media reported.
Kyoto, a former capital, wants to persuade convenience and other 24-hour stores to close late at night so as to improve evening views of the city and cut down on energy use. The Nikkei business daily said closures could last from 11 p.m. to 7 a.m. The move is strongly opposed by the industry, which fears a bad impact on an already troubled sector also grappling with the specter of a higher tobacco tax, which could hit overall sales.  
"Even if we only operate the stores for 16 hours, we can't stop the refrigerators," said Toshiro Yamaguchi, the president of Seven-Eleven Japan Co, which is owned by Seven & I Holdings Co Ltd, at a news conference in Saitama on Tuesday. He said such cuts in operating hours would reduce each store's profit by 20 percent. "If this happens, our current business model will lose its foundation."  
Analysts said that while it is difficult to estimate the potential impact of the move without a concrete plan, their overall impression was that it was likely to be negative. "This could cut profits and lead to less efficient operations and the increased loss of opportunities," said Masafumi Shoda, an analyst at Nomura Securities. "But it depends on the store -- urban stores do better than others. There are some in the countryside that are inefficient."  
Some have suggested that if governments were sincere about reducing carbon emissions there were much more efficient methods, such as cutting back on the huge number of automatic vending machines（自動售貨機）
68. Which of the followings was the first to try to limit convenience store hours?  
A. Saitama                   B. Tokyo               C. Kyoto               D. Nomura Security  
69. What's the main goal of the proposal?  
A. To give employees more free time.  
B. To limit carbon dioxide emissions.  
C. To sell more tobacco products.  
D. To reduce each store’s profit.  
70. How's the convenience store sector doing in Japan?  
A. It is not mentioned.  
B. It's doing great. Business is booming.  
C. Not very well.  
D. It’s about to close.
