The Pentagon confirms that a senior U. S. defense official has presented South Korean authorities with what is termed a "concept proposal" for the withdrawal of 12,500 troops from the Peninsula by the end of next year. There are about 37,000 U. S. troops in South Korea now. The senior official, Deputy Undersecretary of Defense for Asian and Pacific Affairs Richard Lawless, unveiled the proposal in talks Sunday in Seoul. Mr. Lawless made clear the 1/3 cut in the U. S. force in South Korea will include a brigade being transferred to Iraq later this year. That move involving 3,600 troops was announced last month.

With the explosion of digital media in recent years, a growing number of students are spending their time in front of the small screen---whether it’s a Smartphone or tablet. In just two years, the number of US children using digital media has doubled to 72 percent, according to a survey by Common Sense Media. On average, students spend about two hours a day in front of the screen. Watching TV makes up half of this time. But gradually, the time children spend watching TV is decreasing, with more and more time being given to digital media. Some of the common things kids do with digital media are playing games, watching videos and sending messages to friends. The digital world can be used very effectively. In the survey, 74 percent of teachers said that digital media would improve students’ learning. As students can quickly get hold of information they need. However, without guidance from teachers or parents, digital media may have bad influence on students’ attention span and communication skills. So it’s always best to use your smartphone and tablet carefully. When using digital media, you need to find a balance. Just like study, too much can lead to information overload, and give you a headache. Also, make sure your smartphone or tablet doesn’t take priority over more important tasks. Give your eyes a rest, and remember: offline is just as fun as online. 1. Two years ago, the number of US children who use digital media made up _____.{A; B; C} A. 72% B. 36% C. 74% 2.

On August 27th the firm said that the successor to its Windows XP operating system, code-named Longhorn, will go on sale in 2007 without one of its most impressive features, a technique to integrate elaborate search capabilities into nearly all desktop applications. (On the bright side, Longhorn will contain advances in rendering images and enabling different computing platforms to exchange data directly between applications.) It is a big setback for Microsoft, which considers search technology a pillar of its future growth—not least as it competes against Google. The firm's focus on security championed by Bill Gates himself—took resources away from Longhorn, admits Greg Sullivan, a lead product manager in the Windows client division. Programmers have been fixing Windows XP rather than working on Longhorn. In mid-August, Microsoft released Service Pack 2, a huge set of free software patches and enhancements to make Windows XP more secure. Though some of the fixes turned out to have vulnerabilities of their own, the patches have mostly been welcomed. Microsoft's decision to forgo new features in return for better security is one that most computer users will probably applaud. Yet ironically, as Microsoft slowly improves the security of its products-by, for instance, incorporating firewall technology, anti-virus systems and spam filters its actions increasingly start to resemble those that, in the past, have got the firm into trouble with regulators. Is security software an "adjacent software market", in which case Microsoft may be leveraging its dominance of the operating system into it？ Integrating security products into Windows might be considered "bundling" which, with regard to web browsing, so excited America's trustbusters in the 1990s. And building security directly into the operating system seems a lot like "commingling" software code, on which basis the European Commission ruled earlier this year that Microsoft abused its market power through the Windows Media Player. Microsoft is appealing against that decision, and on September 30th it will argue for a suspension of the commission's remedies, such as the requirement that it license its code to rivals. Just last month, the European Union's competition directorate began an investigation into Microsoft and Time Warner, a large media firm, on the grounds that their proposed joint acquisition of Content Guard, a software firm whose products protect digital media files, might provide Microsoft with, undue market power over digital media standards. The commission will rule by January 2005. Microsoft, it seems, in security as elsewhere, is going to have to get used to being punished for its success. Its Windows monopoly lets it enjoy excessive profits but the resulting monoculture makes it an obvious target for viruses and regulators alike. That Microsoft's three tasks are colliding is reflected in the fact that ______. A．the new operating system will be marketed at a discount B．search will be removed from the new operating system C．all search capabilities will be combined into the desktop D．images and data will be exchanged more directly

When you go to a blood bank to give plasma, they ask you a series of questions to determine if you are eligible to donate. Obviously, they don't want to risk accepting contaminated blood, so they will ask about your sexual history, current health status and other related questions, including whether or not you have gotten a tattoo or piercing within the last 12 months. All blood that is donated is screened for disease such as HIV, Hepatitis, Syphilis and other common blood- born ailments. However, it goes without saying that it is a waste of the blood bank's and the donor's time to harvest blood that is tainted and thus worthless. So, in order to avoid wasted time, they ask these questions to screen the potential donor. And although even I would be quick to say that tattooing and piercing are much safer than some medical professionals like to indicate, there is still always a chance of getting and carrying a disease unknowingly from a tattoo or piercing, especially Hepatitis. That has been the object of many heated arguments and stringent regulations. If you should happen to contract a disease from a tattoo or piercing, it should show up in a screening after 12 months, which is the reason for the waiting period. Yes, maybe it's a little over-precautious, but would you want to be the one on the receiving end of dirty blood？ If there, is even a chance, it is better to be safe than sorry. (37) A．Swim in public pools. B．Give blood. C．Over exert yourself. D．Expose your skin to the sun.
