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.

Talking on a mobile phone is expensive, so a lot of people send text messages. Text messages are much cheaper than talking on a mobile phone, and you can make it cheaper by making the words shorter. You can do this by taking out “unimportant” letters in the words and using numbers instead of words (2 =" to," 3 =" free," 4 =" for," 8 =" ate," so h8 =" hate," etc.). You can also keep away from using punctuation (标点). Here is an example: Do U wnt 2 g 2 th cnma tnite (Do you want to go to the cinema tonight?)
What do you think these text messages mean?
Whr hv U bn? Iv bn wtng hrs fr a cll.
Im hm nw, why nt gv me a cll.
I gt a txt mssge frm my frnd. Shes hvng a prty on Strdy.
Mobile phone users have developed a group of symbols (符号) to show how they feel. They are called emoticons, and there are some examples below. To read an emoticon, you have to look at it sideways. For example, if you say something in a text message that is a joke, you can follow it with a smiling face. Like this: Why didt u call me? I’m so sad.   (
Here are some others. Can you think of text messages where you could use them?
) laughing     ( sad    ＜ really sad
Ⅴ shouting    |·| asleep   ：0 shocked
8·| surprised    \·o bored
【小题1】Why are text messages popular?

Below is some advice on how to prevent colds and flu.

That cold January night, I was growing sick of my life in San Francisco. There I was, walking home at one in the morning after a tiring practice at the theater. With opening night only a week away, I was still learning my lines. I was having trouble dealing with my part-time job at the bank and my acting at night at the same time. As I walked, I thought seriously about giving up both acting and San Francisco. City life had become too much for me.
As I walked down empty streets under tall buildings, I felt very small and cold. I began running, both to keep warm and to keep away any possible robbers(抢劫犯). Very few people were still out except a few sad-looking homeless people under blankets.
About a block from my apartment, I heard a sound behind me. I turned quickly, half expecting to see someone with a knife or a gun. The street was empty. All I saw was a shining streetlight. Still, the noise had made me nervous, so I started to run faster. Not until I reached my apartment building and unlocked the door did I realize what the noise had been. It had been my wallet falling to the sidewalk.
Suddenly I wasn’t cold or tired anymore. I ran out of the door and back to where I’d heard the noise. Although I searched the sidewalk anxiously for fifteen minutes, my wallet was nowhere to be found.
Just as I was about to give up the search, I heard the garbage truck(垃圾车) pull up to the sidewalk next to me. When a voice called from the inside, “Alisa Camacho?” I thought I was dreaming. How could this man know my name? The door opened, and out jumped a small red-haired man with an amused look in his eyes. “Is this what you’re looking for?” he asked, holding up a small square shape.
It was nearly 3 a.m. by the time I got into bed. I wouldn’t get much sleep that night, but I had got my wallet back. I also had got back some enjoyment of city life. I realized that the city couldn’t be a bad place as long as people were willing to help each other.
