"My previous work didn't have an artistic element to it, whereas this is exciting and creative," he says. "I really enjoy the design side."(47).

The Choice of an Occupation<br>Most worthwhile careers require some kind of specialized training.

Technology Transfer in Germany<br>When it comes to translating basic research into industrial success, few nations can match Germany. Since the 1940s, the nation&39;s vast industrial base has been fed with a constant stream of new ideas andexpertisefrom science. And though German prosperity (繁荣) has faltered (衰退) over the past decade because of the huge cost of unifying east and west as well as the global economic decline, it still has an enviable record for turning ideas into profit.<br>Much of the reason for that success is the Fraunhofer Society, a network of research institutes that exists solely to solve industrial problems and create sought-after technologies. But today the Fraunhofer institutes have competition. Universities are taking an ever larger role in technology transfer, and technology parks are springing up all over. These efforts are being complemented by for pumping into start-up companies.<br>Such a strategy may sound like a recipe for economic success, but it is not without its critics.These people worry that favouring applied research will mean neglecting basic science,eventually starving industry of fresh ideas. If every scientist starts thinking like an entrepreneur (企业家 ) , the argument goes, then the traditional principles of university research being curiosity-driven, free and widely available will suffer. Others claim that many of the programmes to promote technology transfer are a waste of money because half the small businesses that are promoted are bound to go bankrupt within a few years.<br>While this debate continues, new ideas flow at a steady rate from Germany&39;s research networks, which bear famous names such as Helmholtz, Max Planck and Leibniz. Yet it is the fourth network, the Fraunhofer Society, that plays the greatest role in technology transfer.<br>Founded in 1949, the Fraunhofer Society is now Europe&39;s largest organisation for applied technology, and has 59 institutes employing 12,000 people. It continues to grow. Last year, it swallowed up the Heinrich Hertz Institute for Communication Technology in Berlin. Today, there are even Fraunhofers in the US and Asia.<br>What factor can be attributed to German prosperity？ 查看材料

A. Technology transfer
B. Good management
C. Hard work
D. Fierce competition

They have asked for independence and a separate state. Since 2004, the insurgents (叛乱者) have carried out numerous attacks in the south and more than 1,900 people have been killed. __________ (48)<br>But Thai Prime Minister Surayud Chulanont said on Monday that domestic politics rather than the Muslim insurgency was behind the bombings. "It is likely related to people who lost their political benefits," Surayud said, referring to Thaksin Shinawatra.__________ (49) Surayud was later appointed interim (临时的) prime minister.
