【简答题】
New technology links the world as never before. Our planet has shrunk. It's now a 'global village' where countries are only seconds away by fax or phone or satellite link. And, of course, our ability to benefit from this high-tech communication equipment is greatly improved by foreign language skills. Deeply involved with this new technology is a kind of modem businesspeople who have a growing respect for the economic value of doing business abroad. In modern markets, success overseas often helps support home business efforts. Overseas assignments are becoming increasingly important to advancement within executive ranks (管理层). The executive stationed in another country no longer need fear being 'out of sight and out of mind.' He or she can be sure that the overseas effort is central to the company's plan for success, and that promotions often follow or accompany an assignment abroad. If an employee can succeed in a difficult assignment overseas, superiors will have greater confidence in his or her ability to cope back in the United States where cross-cultural considerations and foreign language issues are becoming more and more popular. Thanks to a variety of relatively inexpensive communication devices with business applications, even small businesses in the United States are able to get into international markets. English is still the international language of business. But there is an ever-growing need for people who can speak another language. A second language isn't generally required to get a job in business, but having language skills gives a candidate the edge when other qualifications appear to be equal. The employee posted abroad who speaks the country's official language has an opportunity to fast-forward certain negotiations, and can have the cultural insight to know when it is better to move more slowly. The employee at the home office who can communicate well with foreign partners over the telephone or by fax machine is an obvious asset(资产)to the firm. 小题1:What is the author's attitude toward high-tech communications equipment?

A.are eager to work overseas B.have to get familiar with modem technology C.are attaching more importance to their overseas businesses D.are gaining more economic benefits from domestic businesses 小题3:In paragraph 3, 'out of sight and out of mind' (Line 2-3) probably means ________. A.leaving all care and worry behind B.being totally out of touch with business at home C.being unable to think properly for lack of insight D.missing opportunities for promotion when abroad 小题4:According to the passage, what is an important consideration of international corporations in employing people today? A.Ability to speak the customer's language. B.Connections with businesses over seas C.Technical know-how. D.Business experience. 小题5:The advantage of employees having foreign language skills is that they can _________. A.fast-forward their proposals to their bosses.
