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
Her paper is published in the online journal PLoS Medicine.

Consumers are being confused and misled by the hodge-podge （大杂烩） of environmental claims made by household products, according to a “green labeling” study published by Consumers International Friday．
Among the report’s more outrageous （令人无法容忍的） findings, a German fertilizer described itself as “earthworm friendly”, a brand of flour said it was “non-polluting” and a British toilet paper claimed to be “environmentally friendlier”．
The study was written and researched by Britain’s National Consumer Council （NCC） for lobby group Consumer International．It was funded by the German and Dutch governments and the European Commission．
“While many good and useful claims are being made, it is clear there is a long way to go in ensuring shoppers are adequately informed about the environmental impact of products they buy,” said Consumers International director Anna Fielder．
The 10-country study surveyed product packaging in Britain．Western Europe, Scandinavia and the United States．It found that products sold in Germany and the United Kingdom made the most environmental claims on average．
The report focused on claims made by specific products, such as detergent （洗涤剂）, insect sprays and by some garden products．It did not test the claims, but compared them to labeling guidelines set by the International Standards Organization （ISO） in September, 1999．
Researchers documented claims of environmental friendliness made by about 2,000 products and found many too unclear or too misleading to meet ISO standards．
“Many products had specially-designed labels to make them seem environmentally friendly, but in fact many of these symbols mean nothing,”said report researcher Philip Page．
“Laundry detergents made the most number of claims with 158．Household cleaners were second with 145 separate claims, while paints were third on our list with 73．The high numbers show how confusing it must be for consumers to sort the true from the misleading．” he said．
The ISO labeling standards ban vague or misleading claims on product packaging, because terms such as “environmentally friendly” and “non-polluting” cannot be tested．“What we are now pushing for is to have multinational corporations meet the standards set by the ISO．” said Page．
1．According to the passage, the NCC found it outrageous that ____．
A．all the products surveyed claim to meet ISO standards
B．the claims made by products are often unclear or misleading
C．consumers would believe many of the manufactures’claim
D．few products actually prove to be environmentally friendly
2．A study was carried out by Britain’s NCC to ____．
A．find out how many claims made by products fail to meet environmental standards
B．inform the consumers of the environmental impact of the products they buy
C．examine claims made by products against ISO standards
D．test the guidelines set by the International Standards Organization
3．What is one of the consequences caused by the many claims of household products?
A．They are likely to lead to serious environmental problems
B．Consumers find it difficult to tell the true from the false
C．They could arouse widespread anger among consumer
D．Consumers will tend to buy products they don’t need
4．It can be inferred from the passage that the lobby group Consumer International wants to ____．
A．make product labeling satisfy ISO requirements
B．see all household products meet environmental standards
C．warn consumers of the danger of so-called green products
D．prove the efforts of non-polluting products

Today, among people everywhere, there is an increasing awareness and worry about the steady growth in the world’s population．A recent survey conducted by the United Nations Fund for Population Activities （UNFPA） reported that this growth will continue until the end of the next century．For developing countries alone, the annual average population growth is, at present, 4．6% compared to 2．0% for developed countries．At this rate, the world’s population will reach 10．2 billion by the turn of the 21st century．With the growth in population is the problem of food security… the guarantee of a steady supply of food．The unstoppable growth in population justifies the Malthusian Doctrine that population of a region will continue to grow unless checked, and this is of course alarming since it will inevitably lead to food shortages of considerable proportions．
Our forests are an abundant source of food and fuel, two items essential in sustaining life．Above 30% of the world’s land surface is covered by such forests．In Asia alone, more than two billion people depend heavily on forest products for their subsistence and survival．To maintain a reasonable balance between population growth and food supply, this natural source of life — sustaining food and fuel must be conserved and protected from its worst enemy — man himself．It is appalling （令人震惊的） to note that in many developing countries, which are themselves heavily hit by population-food imbalance, governments approve the cutting down of forests to meet their immediate needs for saleable timber, and also for agricultural land．Often the cutting down and burning of forests is conducted with total abandon owing to the absence of sound forestry techniques and management．At the rate tropical forests are now being cleared each year, the world’s tropical forests will be completely destroyed within the next 100 years．
In order to maintain food security for the world’s population, the Food and Agricultural Organization of the United Nations （FAO） has launched a campaign aimed at ensuring food supply, maximizing stability in the flow of this supply and ensuring access to it by all．Forestry, according to the FAO, plays a vital role in making it possible to fulfill all its three objectives．Its most important role is that of conserving soil and water．Trees provide natural protection against soil erosion （侵蚀） by absorbing the excess water brought by heavy rains．
1．The first paragraph tells us that ____．
A．the flow of food supply is the result of population increase．
B．the world population has reached the 10-billion mark．
C．the problem of population growth has caused considerable alarm in a few countries．
D．the problem of food supply goes hand-in-hand with population increase．
2．The Malthusian Doctrine presents ____ as far as world population is concerned．
A．an optimistic view of the future     B．a pessimistic outlook for the future
C．an encouraging picture          D．an indifferent picture
3．In this context, “this natural source of life — sustaining food and fuel” （in Paragraph 2） refers to ____．
A．the flow of food supply           B．forests
C．woodland products               D．man’s worst enemy
4．The three objectives of the FAO can be replaced by ____．
A．stopping population growth       B．increasing food production
C．achieving food security          D．ensuring maximum utilization of forests

第一节：阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
When I was an education official in Palo Alto, California．Polly Tyner, the president of our school board, wrote a letter that was printed in the Palo Alto Times．Polly’s son, Jim, had great difficulty in school．He was classified as educationally disabled and required a great deal of patience on the part of his parents and teachers．But Jim was a happy kid with a great smile that lit up the room．His parents acknowledged his academic difficulties, but always tried to help him see his strengths so that he could walk with pride．Shortly after Jim finished high school, he was killed in a motorcycle accident．After his death, his mother submitted this letter to the newspaper．
Today we buried our 20-year-old son．He was killed instantly in a motorcycle accident on Friday night．How I wish I had known when I talked to him last that it would be the last time．If I had only known I would have said, “Jim, I love you and I’m very proud of you．”
I would have taken the time to count the many blessings he brought to the lives of the many who loved him．I would have taken the time to appreciate his beautiful smile, the sound of his laughter, his genuine love of people．
When you put all the good qualities on the scale and try to balance all the irritating phenomena such as the radio which was always too loud, the haircut that wasn’t to our liking, the dirty socks under the bed, etc．, your angry feelings won’t amount to much．
I won’t get another chance to tell my son all that I would have wanted him to hear, but, other parents, you do have a chance．Tell your young people what you would want them to hear if you knew it would be your last conversation．The last time I talked to Jim was the day he died．He called me to say, “Hi, Mom! I just called to say I love you．Got to go to work．Bye．” He gave me something to treasure forever．
If there is any purpose at all for Jim’s death, maybe it is to make others appreciate more of life and to have people, especially family members, take the time to let each other know just how much we care．
1．According to the passage, we know that ____．
A．Jim kept to himself B．Jim did very well in his studies
C．Jim’s parents were patient with him       D．Jim failed to finish his high school
2．The underlined word “irritating” in Paragraph 4 means ____．
A．annoying         B．aggressive     C．impatient         D．thrilling
3．By writing the letter printed in the Palo Alto Times, the author intends to ____．
A．mourn her son’s sudden death in a traffic accident
B．remind people to be cautious of motorcycles
C．advise people to take the chance to express their love in time
D．appreciate more of life than ever before
