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.

A. assessment           B. comment          C. introduction     D. background   

If you don’t have a college degree, you’re at greater risk of developing memory problems or even Alzheimer’s (老年痴呆). Education plays a key role in lifelong memory performance and risk for mental disorder, and it's well documented that those with a college degree possess a cognitive（认知的） advantage over those less educated in middle and old age.

       Now, a large national study from Brandeis University published in the American Journal of Geriatric Psychiatry shows that those with less schooling can significantly make up for poorer education by frequently engaging in mental exercises such as word games, puzzles, reading, and lectures.

       “The lifelong benefits of higher education for memory in later life are quite impressive, but we do not clearly understand how and why these effects last so long,” said lead author Margie Lachman, a psychologist. She suggested that higher education may encourage lifelong interest in cognitive efforts, while those with less education may not engage as frequently in mental exercises that help keep the memory agile (敏捷地).

       But education early in adulthood does not appear to be the only route to maintain your memory. The study found that intellectual activities undertaken regularly made a difference. “Among individuals with low education, those who are engaged in reading, writing, attending lectures, doing word games or puzzles once a week or more had memory scores similar to people with more education,” said Lachman.

       The study, called Midlife in the United States, assessed 3,343 men and women between the ages of 32 and 84 with an average age of 56 years. Almost 40 percent of the participants had at least a 4-year college degree. The researchers evaluated how the participants performed in two cognitive areas, verbal (言语的)memory and executive function --- brain processes involved in planning, abstract thinking and cognitive flexibility. Participants were given a series of tests, including tests of verbal fluency, word recall, and backward counting.

       As expected, those with higher education said they engaged in cognitive activities more often and also did better on the memory tests, but some with lower education also did well, explained Lachman.

       “The findings are promising because they suggest there may be ways to level the playing field for those with lower educational achievement, and protect those at greatest risk for memory declines,” said Lachman. “Although we can not rule out the possibility that those who have better memories are the ones who take on more activities, the evidence is consistent with cognitive plasticity (可塑性), and suggests some degree of personal control over cognitive functioning in adulthood by adopting an intellectually active lifestyle.”

What is the text mainly about?

       A. Higher education has a better cognitive advantage.

       B. Better memories result from college degree.

       C. Cognitive activity does good to one’s mind.

       D. Poor education has more risk of memory declines.

According to the result of Margie Lachman’s study, we can conclude that ________.

 A. education is responsible for the lifelong memory performance and risk for mental disorder

 B. education early in adulthood can be the only route to maintain your memory

 C. those with higher education did better on the memory tests than those with lower education

 D. an intellectually active lifestyle does help to maintain your memory

What do we know about the study called Midlife?

     A. Participants each were given a battery to test their memory.

     B. The average age of the participants are 56 years old.

     C. Participants had to perform in one of the two cognitive areas.

     D. One in four of the participants had a 4-year college degree.

Why are the findings of the Lachman’s study promising?

     A. The lower educated may have the same opportunities to keep up memory.

     B. We may have ways to cure the people who have memory declines.

     C. Adopting a different lifestyle can control cognitive functioning.

     D. We can find out the possibility to have better memories.

Younger adults who get either little sleep or a lot of it may see a greater expansion in their waistlines（腰围）over time, a study published suggests. Researchers found that among black and Hispanic adults younger than 40, those who typically slept for five hours or less each night had a greater accumulation of belly fat over the next five years, versus（相比于） those who averaged six or seven hours. Those who slept eight hours or more in bed each night also showed a bigger fat gain - but it was less obvious than that seen in "short sleepers."
The study, reported in the Journal Sleep, does not prove that too little or too much sleep directly leads to excess fat gain. But the findings support and extend those of other studies linking sleep duration - particularly a lack of sleep - to weight gain and even to higher risks of diabetes(糖尿病) and heart disease. Among participants younger than 40, the study found, those who said they slept for five hours or less each night gained more belly fat than those who averaged six or seven hours of sleep. On average, short sleepers showed a 32 percent gain in visceral（内脏的）fat, versus a 13 percent gain among those who slept six or seven hours per night, and a 22 percent increase among men and women who got at least eight hours of sleep each night. A similar pattern was seen with superficial abdominal（腹部）fat.
The findings, according to lead researcher Dr. Kristen G. Hairston, support the belief that sleep habits affect weight and health in general. "Sleep is an important part of your overall health - not just in whether you're tired during the day," she said.
There may be indirect effects; people who get too little sleep may be too tired during the day to exercise, while those who spend a lot of time in bed may spend less time being active, relative to people who sleep fewer hours. Research also suggests that sleep loss alters people's levels of appetite-regulating hormones（荷尔蒙）- which could, in theory, cause them to overeat. Depression, which often affects people's sleep and has been linked to weight gain, could also be a factor, Hairston noted.

Research shows that much of our predisposition （倾向） towards determination, sociability and self - control and sense of purpose is in our genes．In fact, our DNA plays a bigger role in influencing these traits （ characteristics）than our upbringing （儿童期的教养）and the company we keep．Taken together, these aspects of personality can make the difference between success and failure, say the Edinburgh University researchers．        
They questioned more than 800 pairs of twins about their attitudes to life to tease apart the influences of nature and nurture．Comparing identical twins, who share all their DNA and their up bringing, with non-identical twins, who have a shared background but are no more genetically alike than other brothers and sisters, is a technique often used by researchers to quantify the influence of genetics．
The results, published in the Journal of Personality, showed that genes play a much bigger role than lifestyle, with self-control particularly etched （铭刻） into our DNA．                   
Our genes a222so largely determine how determined and persistent we are．This is important in terms of success, as someone who refuses to give up is more likely to achieve their dreams than someone who throws in the towel at the first hiccough．
Researcher Professor Timothy Bates said, "Ever since the ancient Greeks, people Lave de hated the nature of a good life and the nature of a virtuous life．Why do some people seem to manage their lives, have good relationships and cooperate to achieve their goals while others do not? Previously,  the role of family and the environment around the home often controlled people' s ideas about what affected psychological well-being．However, this work emphasizes a much more powerful influence from genetics．"
However, those who haven' t been dealt a helpful hand of genes shouldn' t he too depressed．The professor says a sense of purpose is the key and advises those who are eager for success to focus their thoughts on making a difference．
【小题1】What does the result of the research indicate?

A．Our DNA is the only factor to decide our traits．
B．Our DNA plays a decisive role, in achieving success．
C．Education plays little part in the formation of our character．
D．Society has Little effect on us in our personality．
【小题2】The underlined part in Paragraph 4 refers to someone who                ．
A．is born successfulB．determines to make a difference

【小题3】Timothy Bates mentions the ancient Creeks in order to indicate that          ．
A．some people can live a good life because they can manage their lives
B．people haven't made it clear yet what is the key personality trait（持点,特征） to be a success
C．in ancient Greece the role of family and the environment was ignored
D．the relationship between personality and success has always been people's concern
【小题4】According to the passage, the key personality trait is            ．

A．How do people work hard?B．Why can some people succeed?
C．DNA determines success or failureD．Several factors determine personality

Cancer researchers urged people on Wednesday to take more vitamin D to lower risk of cancer, saying studies showed a clear link. “Our suggestion is for people to increase their intake (吸入，摄入), through diet or a vitamin supplement,” Dr. Cedric Garland said in a telephone interview.
Garland's research team reviewed 63 studies, including several large long-term ones, on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. “There's nothing that has this ability to prevent cancer,” he said, urging governments and public health officials to do more to fortify (增强) foods with vitamin D. Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health. Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units（IU）a serving. “People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day” Garland said, adding that it was well within the safety guidelines established by the National Academy of Sciences.
The authors said that taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine.
“African Americans, who don't produce as much of the vitamin because of their skin colour, could also benefit significantly from a higher intake,” the authors said.
【小题1】According to the passage, people are advised to take more Vitamin D, because__.

A．it is nutritiousB．it can‘t harm people’s health
C．it can lower cancer riskD．it is not taken enough every day
【小题2】Which of the following can not help people get more Vitamin D?
A．Have some sunshineB．Have more meat
C．Have more fortified cheeseD．Have a vitamin supplement
【小题3】Which of the following food can lower people‘s chance of getting cancer?
A．MilkB．Fortified orange juice C．Fortified yogurtD．All of the above
