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 . 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 , 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  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 . 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. The research is done by  _  . A) using computer programs and collecting data from clinics B) giving medicine to newly diagnosed patients with AIDS C) urging countries to focus on treating more patients earlier D) publishing her paper in the online journal PLoS Medicine

"If you want to see a thing well, reach out and touch it!"  That may seem a strange thing to say. But touching things can help you to see them better. Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth and cool the ball is. You can feel how heavy the glass is. When you feel all these about the ball, you really see it. With your skin, you can feel better. For example, your fingers can tell the difference between two coins in your pocket. You can feel a little drop of water on the back of your hand, too. All children soon learn what "Don't touch!" means. They hear it often. Yet most of us keep on touching things as we grow up. In shops, we touch things as we might buy: food, clothes. To see something well, we have to touch it. There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that is touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin. At first, it is not easy to feel these things. You are too used to them! Most museums are just for looking. But today some museums have some things to touch. There you can feel everything on show. If we want to see better, reach out and touch. Then you will really see. Which of the following can be the best title of the story? A) Touching by Feeling B) To See or to Feel? C) To See Better---Feel D) Ways of Feeling

Q: "Men get all the breaks!" the veteran   teacher announced to me. A cold greeting. Her stare stabbed like an icicle  . "Hello," I countered, extending my hand. "I guess we'll be teaching together this year." "I swear, all you have to do is wear pants and walk into an elementary school and they hire you! It makes me sick!" I would have responded, but she turned her back to me and stomped off down the hall. Who would have imagined that the biggest challenge I would face during my first year on the job would not be students, but fellow teachers? "You can't put that there!" Another teacher burst into my classroom. "You can't put the teacher's desk at the back of the room!" "Pardon?" "If you put your desk way back there, you won't be able to see them cheating!" Next I was told I must not arrange student desks into abutting clusters because "the students might talk too much." At home my wife kept assuring me, "You're there for the kids. When you meet your students, things will be different." And she was right. One day the bell rang and there were thirty-five wonderful sixth graders sitting at their desks (still arranged in clusters) and it was different. I was happy. "Welcome to sixth grade." I began the year as I'd rehearsed for months. "You'll notice," I continued, "my desk is at the back of the room." They chuckled. "I don't want that desk between us. I want to be involved in your learning and involved in your lives." In the days that followed, I ate with my students at lunch (" _ "); I played with my students at recess (" _ "); I read with my students in the library (" _ "); I even stayed after school with some boys who got in trouble with the principal (" _ "). I went home to my wife. "Don't worry," she said. "They're just threatened by you because you're new and you're good. Let the other teachers know you're not a threat. Just keep being nice to them." Obediently, I pulled out the Golden Rule, dusted it off, and vowed to start again. As I did with the children, I started looking for specific, positive things... The writer's wife thought that his colleagues felt threatened because   _  . A) he hung around with students B) he was a competitive newcomer C) he ignored their advice D) he was an impolite coworker
A: B


(Question)
World Future Society People People may live for up to 120 years and use new technology to help when people go blind, deaf and have other problems. The number of people over a hundred years old could go from 135,000 today to 2.2 million people by 2050. By 2015 people think that 100 million workers will be able to work from home for a company in a different country by using the Internet. Money Worldwide e-business will become even more successful with online shops that sell special products for each person, which will be brought to their house the next day. Environment The technology for making energy from wind and the Sun is growing very quickly. In the future wind and Sun energy could become much cheaper and many more countries could use it. This would be very useful in poor countries. The air in big cities would also become much cleaner and healthier as a result. Society and culture  The Internet will help to create more worldwide friendships. Families may spend more time together as people will be able to do 24-hour online banking and shopping. Technology                                               The new science of "nanotechnology" (very small robots or machines) will make all sorts of products smaller and lighter. Very, very small machines could take away rubbish, make things in factories, and help inside the human body by taking away fat. By 2012 people will be able to wear these small machines that look like watches, which will give them lots of information about their body and keep them healthy. How will people go shopping? A) In special shops. B) Using the Internet at certain times. C) Using the Internet any time of the day. D) Using nanotechnology.
