NEW YORK—Microsoft on Monday made anther effort to challenge Apple's iPhone and Google's Android in the exploding smartphone market --- Jaunching a wireless operating system, Windows Phone 7.

    Consumers will consider it "always delightful and thoroughly mine," Microsoft CEO Steve Ballmer said at a launch event. Ballmer said last year that Microsoft had "screwed up" with its Windows Mobile operating system. For example, it failed to keep up with touch-screen innovations that make iPhones and Android phones easy to use.

    Microsoft fell from third to fourth place in market share this year, behind BlackBerry, iPhone and Android. Only 10.8% of smartphone owners used Microsoft's system in August, down from 18% last December.

    But Windows iPhone 7 is "a total departure from anything they've done". Microsoft says it sought to simplify common activities. For example, you can instantly take a picture with a phone's camera by pushing a button on the device. You don't have to first awe, ken it from its sleep mode and launch the camera application. You also can program the phones to automatically upload photos to Facebook or other social network sites in a couple of seconds. Users can easily work with Microsoft Office contact and calendar information as well as documents created in Microsoft's Word, Excel and PowerPoint.

    The phones will not show videos built on Adobe's Flash platform, widely used by services including You Tube and Hulu.

    AT&T will offer the first Windows Phone 7 smartphone, the Samsung Focus, on Nov. 8. Soon after, it will have the LG Quantum and HTC Surround. Each will cost $199.99 with a two-year service contract. T-Mobile will have two Windows Phone 7 models out for the holiday shopping season: the HTC HD7 and Dell Venue Pro. It did not say how much they'll cost.

1. What is the main idea of paragraph 4?

      A．Why Microsoft foil behind others.

      B．How to use Windows phone 7.

      C．Advantages of Windows phone 7.

     D．Speed of Windows phone 7.

2. What does the underlined phrase "screwed up" in the 2^nd paragraph probably mean?

      A．To make a bad mistake.                     B．To make big progress.

      C．To achieve main goals.                      D．To keep up with others.

3. Which of the following phones will NOT use Windows Phone 7 operating system?

      A．Quantum.          B．Surround.        C．Android              D．Focus.

4. Why did Microsoft see a drop in market share last year?

      A．Because its operating system didn't catch up with changes.

      B．Because its phones can't show videos from YouTube.

      C．Because it was inconvenient to take photos using its phones.

      D．Because its system was based only on Microsoft soft wares.

5. Which of the following can be the best title of the passage?

      A．Smartphone Market Welcomes New Giant

     B．Microsoft to Fight Back on Smartphone

     C．Mobile Phones Getting Smarter and Easier

     D．Microsoft Proved a Failure in Smartphone

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.

Christopher Thomas, 27, was a writer by night and a teacher by day when he noticed he was always tired and was losing weight fast. Diagnosed with diabetes(糖尿病), Thomas would need to inject himself with insulin(胰岛素) three times a day for the rest of his life or risk nerve damage, blindness, and even death. And if that weren't bad enough, he had no health insurance.

After a month of feeling upset, Thomas decided he'd better find a way to fight back. He left Canton, Michigan for New York, got a job waiting tables, nicknamed himself the Diabetic Rockstar, and created diabeticrockstar.com, a free online community for diabetics and their loved ones—a place where over 1,100 people share personal stories, information, and resources.

    Jason Swencki’s son, Kody, was diagnosed with type diabetes at six. Father and son visit the online children's forums(论坛) together most evenings. "Kody gets so excited, writing to kids from all over," says Swencki, one of the site's volunteers. "They know what he's going through, so he doesn't feel alone."

Kody is anything but alone: Diabetes is now the seventh leading cause of death in the United States, with 24 million diagnosed cases. And more people are being diagnosed at younger ages.

    These days, Thomas's main focus is his charity（慈善机构）, Fight It, which provides medicines and supplies to people—225 to date—who can't afford a diabetic's huge expenses. Fight-it.org has raised about $23,000—in products and in cash. In May, Thomas will hold the first annual Diabetic Rockstar Festival in the Caribbean.

    Even with a staff of 22 volunteers, Thomas often devotes up to 50 hours a week to his cause, while still doing his full-time job waiting tables. "Of the diabetes charities out there, most are putting money into finding a cure," says Bentley Gubar, one of Rockstar's original members. "But Christopher is the only person I know saying people need help now."
