Treatment for HIV has become more widespread, especially in poorer countries. It's also become cheaper, as medicine companies have lowered their prices for life-saving anti-retroviral drugs(抗逆转录病毒药物). But these drugs are still expensive and many countries are looking to create the biggest impact with limited resources. That's where World Health Organization guidelines come in, says Rochelle Walensky, a disease researcher from Harvard.
Walensky and her colleagues used computer programs to model the most cost-effective disease interventions(干预), as well as collected data from clinics in Africa and India about what works best. They found that among the choices of what to do first, earlier anti-retroviral therapy (疗法)improved five-year survival dramatically and resulted in the longer life expectancy. But cost-effective doesn't always mean affordable, especially for governments in poor countries. Countries still have to make difficult choices about how much treatment they can afford.
People in Nairobi, Kenya on Thursday, Dec. 9, 2010, protest a potential free trade area agreement between the EU and India that could see cheap anti-AIDS drugs phased out(逐步淘汰). However, Walensky notes that first-line anti-retrovirals—those medicine given to newly diagnosed patients that can keep away from symptoms for years - are much cheaper than they were a decade ago. "Second-line therapy have come down quite a bit but not to the level of first-line and countries are having a hard time affording them and increasingly over time, people are going to fail first-line therapy and they're going second-line therapy and then, eventually, they're going to need third-line therapy, some of them."
According to Walensky, history has shown that drug prices can come down when international pressure is applied to drug makers. But for now, she says, countries should focus on treating as many people as they can, as early as possible

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(基础设施)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.
1.People in Shanghai get their daily water mainly from now.
A.the underground B.the rain
C.the Yangtze River D.the Huangpu River
2.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.about half of waste water has been treated already
C.advanced technology makes people use water as much as possible
D.there is plenty surface water and large amount of rain at present
3.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
4.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, b, c, d B.b, c, e, f C.b, c, d, e D.a, b, e, f
5.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.all the family toilets will be renovated to save water within 3 years

You’re finishing up your history homework when your cell phone rings. You’ve got 30 minutes to reach head-quarters, get your equipment packed and receive your task. There’s a lost hiker in the mountains near the edge of town. Your task: find the missing person; provide emergency medical treatment, if necessary; and be prepared to operate 48 hours on your own with only the supplies you carry.
Sounds like some kind of film’s plot? Not if you’re a member of the Arapahoe teen rescue patrol in the suburbs of Denver. About 25 teen guys and girls are active members of this search, rescue and emergency organization, and they know firsthand that you don’t have to be an adult to save lives.
These 9th-through-12th graders are the real deal when it comes to emergency services. In fact, they’re the only teen-commanded patrol in the nation. Sure they have adult advisers to turn to if necessary, but in the field it’s a teen patrol officer calling the shots — sometimes even giving direction to adults.
Members are trained in rock-high-angle,swift-water and avalanche rescue (雪崩施行营救), winter and alpine operation , wilderness life support and emergency care, among other skills. They also regularly ride along with the local fire and police departments, providing support such as security details and evidence searching.
When asked what qualities make a good patrol member, founder and president Stan Bush named good physical conditioning and an interest in helping people. “We put in lots and lots of hours helping people in trouble,” he says. “So if a person is not really interested in doing that kind of thing, he won’t last as a member.”
1.In the first paragraph, the author describes ______.
A. a plot in some kind of film B. a teen patrol member’s life
C. an emergency rescue D. a lost hiker in trouble

A. be strong and interested in offering help
B. be a 9th-through-12th grader
C. finish your history homework first
D. spend many hours helping people first

科目:高中英语 来源:2012-2013学年江西南昌10所省高三第二次模拟突破冲刺(五)英语试卷(解析版) 题型:阅读理解
My mother, Marisol Torres, came with her family to Australia in the early 1960s. Then my parents’ marriage ended and Mum began the study of precious stones. Her interest in opals (猫眼石) took her to the New South Wales remote town of Lightning Ridge. There were no luxuries (奢华的享受), but she was closer to nature and had a chance to find black opals and make some money.
My mother was beautiful with dark hair and brown eyes, but she was also quiet and shy. Early in the Ridge years, she kept to herself, but later, she started going to the neighbourhood centre to make friends.
It was her dream to mine, but her get-rich-quick thinking was unrealistic. She was cheated and she was never very successful. But she kept a sense of humour and a charming smile.
Then, just as friendships began to blossom, she was diagnosed with cancer and had to return south for treatment. She had the intention of cooking Spanish food as special treat for her Ridge friends, but died too soon. In her honour, my aunt, Marisa, and I fulfilled her desire when we visited the Ridge in March last year.
People who mine the Ridge come from a cross section of society, from lawyers to travels. Looks don’t mean much: it can be hard to tell who is millionaire and who is poor. Opals attracted Sebastian and Hanna Deisenberger to Lightning Ridge. They planned a two-year stay, but became permanent residents.
Then there’s Neil Schellnegger, 45, who moved to the area with his parents when he was a child. He lives with his son, Luke. Luke is a shy 19-year-old boy who enjoys helping his dad. They haven’t had much luck over the past couple of years, but their passion for opals conquers disappointment. They love the peaceful lifestyle.
Danny Hatcher, 38, is a second-generation miner and president of the Lightning Ridge Miners’ Association. He is an optimistic man, driven by the desire to find the perfect opal. “It’s magic,” he explains. “Once you start opal mining you don’t want to do anything else… There is always the potential for finding a million dollars. Nothing beats it.”
It’s a place where dreams --- spiritual or material --- can be fulfilled; a place, for one last bet in life.
1.What made the author’s mother go to Lightning Ridge?
A.The luxurious life there. B.Her new marriage there.
C.Her interest in opals. D.Her passion for nature. .

3.We know from the passage that _________.
A.the rich and the poor can be distinguished by their looks
B.Luke is a successful miner, just like his father
C.Sebastian is planning to leave Lightning Ridge
D.Danny Hatcher’s parents were miners in Lightning Ridge
4.Lightning Ridge is a place where dreams can be fulfilled because __________.
A.there are precious stones and life is peaceful
B.there are people from all walks of life
C.there are rich people who can help poor people
D.there is a lot of gold hidden in the ground
