Sometimes life gets a little dull. What used to be fun and different becomes boring. That is the time to look for something new. It is the time for a big idea to get your mind off everyday life. So why not search for extraterrestrial (地球外的) intelligence? Or even better, why not get your computer to do it for you?

Over two million people have joined the Search for Extraterrestrial Intelligence（SETI）project. Based in California, the SETI project analyzes information taken from a giant radio telescope based in South America. Its task is to look for signals from outer space that might prove that life exists on other planets.

Processing this information is far too big a job for one computer. So the SETI project workers divide the work among volunteers who visit their website. Each computer gets some information to work out from the SETI network through the Internet. This process is often known as “meta-computing”.

It is a wonderful thought. You are sleeping, eating a meal or going out with friends. All this time, your computer is searching the stars for signs that might show something is out there trying to get in touch. Volunteers are proud of being involved in the SETI project. It shows that they understand the potential (潜能) of computing. They know that it is more than just a way of working or playing games.

Meta-computing may also be creating intelligence as well as looking for it. This idea is based on the theory that human intelligence is created by the way in which different parts of the brain communicate with each other. As the saying goes, “The whole is more than the sum of its parts.” People who join the SETI project sometimes wonder whether their computer will become part of a huge network that has learned to think for itself.

二、阅读以下文字，完成92～97题。 当前中国经济是否过热？对这个问题，国内经济界人士认识不大一致，而且标准也不完全一样。①我认为，当前中国经济运行总体上是正常的，但在部分行业已局部出现过热的苗头。当前的经济加速增长，是多年坚持改革开放的成果，更是近几年实施积极的财政政策、稳健的货币政策及其他一系列宏观政策的结果。20世纪90年代中期开始，中国政府对经济发展加强了宏观调控，实现了“软着陆”，克服了亚洲金融危机的影响，深化改革，扩大开放，加入了WTO，国民经济中的各种关系已逐渐理顺，经济进入了一个高速增长的新阶段。 ②投资规模的不断扩大为经济持续增长奠定了坚实基础。近几年中国经济增长的主要源泉是投资，投资增长率都大大高于经济增长率。2002年的投资增长率为17.4%,2003年上半年投资同比增长31.1%，其中集体投资增长37.8%，个体经济投资增长14.1%，利用外资增长44.1%。这必将为下半年和2004年的经济增长打下牢固基础。特别是国债的扩大发行和民间投资的增加，更为建设规模的扩大提供了充足的资金。到2002年底，中国已发行长期建设国债6600亿元，带动银行信贷和其他资金形成了3万多亿元投资规模，2003年又发行1400亿国债，这对新建重大工程、加强技术改造、提高供给能力发挥了重大作用。 中国仍将是国际投资的热土。③2002年中国实际使用外资527亿美元，首次超过美国跃居全球第一位，独占鳌头。2003年第一季度中国吸收外资229.8亿美元，实际使用130.7亿美元，同比增长56.7%。第二季度由于一些跨国公司推迟或取消了原定的来华商谈项目计划，使引资规模有所减少，但这只是一种暂时现象。正如美国摩根大通公司的研究报告指出的那样，中国对外商投资的基本吸引力——中国市场的逐步开放和市场的巨大潜力以及巨大的廉价劳动力供应——未变。④因此，“非典”一经缓解，外资必将大量涌入，中国将是国际资本的长久投资热土。初步预测，2003年实际引资总额将接近600亿美元，为历史最高水平。 在某些部门、某些领域、某些方面已出现了过热的迹象。第一，投资率过高，投资结构不尽合理。盲目建设、重复建设多。第二，金融信贷膨胀。第三，有的产业发展过快，冶金、汽车、化工、建材等行业都出现了投资建厂、扩大规模的热潮。连效率低下的小厂也重新大扩展。对此必须加以重视，并加以防范。国家应加强宏观调控，企业要加强自我约束，科技、中介机构要加强论证工作。尤其是钢铁、汽车、房地产等目前特别“红火”的产业和企业，对未来的市场需求和竞争要进行更多的分析和预测，对技术和资源等方面的约束也要有清醒的估计，不能盲目地扩大生产建设规模，否则在三年后将会出现产品的大量过剩和效益的大幅下降，很多竞争力较弱的企业将会被迫破产或被国内外强势企业兼并。
