作为财务管理目标，股东财富最大化和企业价值最大化通常都只适用于上市公司。（）
参考答案：对
解析：对于已上市的股份公司而言，股东财富等于股票数量乘以每股市价，比较容易确定；而非上市公司无法像上市公司一样随时准确获得公司股价。企业价值最大化目标中，对于非上市公司价值的确定只能通过专门的评估，而评估企业的资产时，容易受评估标准和评估方式的影响，很难做到客观和准确。
Third-generation mobile phones, known as 3G, are the next big step for the telecom industry. Data speed in 3G networks is much quicker than that in present technology. This means users can have high-speed Internet access and enjoy video and CD-quality music on their phones.
"Mobile data is not a dream; it’s not an option but a requirement," said Len Lauer, head of a US communications company, Sprint PCS, at a 3G conference in Bangkok earlier this month.
With 3G, you can forget about text messages telling you yesterday’s news; a 3G phone can receive video news programs, updated four times a day. Internet access will also be much quicker, making it easier to surf the Web on your phone than on your computer at home.
Don’t worry about getting lost. 3G phones offer map services so you can find a new restaurant just by pressing a few keys on your handset.
However, the most impressive part of 3G technology is video calling. With live two-way video communication, you can have face-to-face talks with friends and family on your mobile phone.
Many European countries have already launched the service. In May 2000 the US Government issued five license to run 3G wireless services, while the first 3G phones arrived in Italy in March this year.
International telecom companies can’t wait to sell 3G in China, the world’s largest mobile telecommunications market. But they will have to be patient. At the moment, China is busy testing its 3G-based technologies, networks and services. This will be followed by a trial period before the phones can finally hit the shops.
"We need to create a pool of 3G customers before the large-scale commercial launch of the service," said Fan Yunjun, marketing manager for Beijing Mobile. "We expect that the 3G licenses will be issued late next year.
