They are more powerful and reliable and, importantly, are very economical in terms of energy consumption. Their presence opens a new era in the field of IT technologies and means that the cloud technology is getting closer. These processors are primarily designed for servers, data centers (DPC) and supercomputers. The emergence of this class of devices is not accidental. According to the regional director of Intel in Russia and other CIS states Dmitri Konash who spoke at the event, the market of IT-technology is developing so rapidly that, according to forecasts, by 2015 there will be 15 billion devices connected to the Internet, and over 3 billion of active users. 上周，英特尔公司向俄罗斯和其它独联体国家的公众推出了英特尔Xeon E5-2600系列处理器，它们更加强大可靠，尤其是在能量消耗方面更加经济实惠。它们的问世意味着IT技术领域开始了一个新时代，标志着云技术距离我们越来越近。这些处理器主要是为服务器、数字处理中心和超级计算机设计的。这种处理器的出现并非偶然。根据英特尔公司俄罗斯和其他独联体地区负责人Dmitri Konash就此事发表的看法，IT技术市场的发展速度极快，根据预测，到2015年与英特网连接的设施将有150亿，用户超过30亿。 [Ex 6] 1.

You can't accomplish your goal of mastering the language unless you work at it for years. Well, it sounds as if I'm exag-gerating the difficulties, but the fact is I'm only telling the truth. 2) The principal is somewhat disappointed with the performance of the children. From what she has gathered, some of the teaching staff have neglected their pupils. She has just announced that strict work regulations have been made and that they apply to both Chinese and overseas teachers. 3) The teacher-directed and the child-directed approaches to teaching art represent two ex-tremes of opinion. Too many teacher-directed activities cannot be expected to effectively assist children in learning because of the rigid structure. On the other hand, too many child-directed activities may see a curriculum that is totally unstructured and out of con-trol. There are valid reasons to believe a teacher-guided approach would be a superior way to guide children's development. This approach combines some form of structure with the child leading the direction. II. Confusable Words 1. 1) continual 3) continual

D Original Roadrunner On the current TOP 500 list of worldwide supercomputers released in June 2008, Roadrunner, IBM's new super computer, is rated No.1, exceeding IBM Blue Gene, the former No.1 on the list. IBM calls Roadrunner the world’s first “hybrid” supercomputer. It combines 12,960 IBM Cell chips, which power Sony's PlayStation 3 video game machine, with 6,948 dual-core AMD Opteron chips and 80 terabytes of memory. It runs Red Hat Linux. Roadrunner is billed at the fastest in the world, operating at one petaflop or one thousand trillion calculations per second. So, exactly how fast is the supercomputer? IBM said the speed is roughly equivalent to the combined computing power of 100,000 of today's fastest laptop computers - users would need a stack of laptops 1.5 miles high to match Roadrunner's performance. It would also take the entire population of the earth - about 6 billion people - each working a handheld calculator at the rate of 1 second per calculation more than 46 years to do what Roadrunner can do in one day. IBM said that in the past 10 years, supercomputer power has increased about 1,000 times. Today, just three of Roadrunner's 3,456 tri-blade units have the same power as the 1998 fastest computer. Now, a complex physics calculation that will take Roadrunner one week to complete would have taken the 1998 machine 20 years to finish.
