阅读理解 NEW YORK—Microsoft on Monday made another effort to challenge Apple’s iPhone and Google’s Android in the exploding smartphone market—launching 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 Phone 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 awaken 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 YouTube 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.
