[不定项选择题]资料:Western business visitors are often deadline-driven and unwilling to slow down to the Chinese pace when discussing business. But in China the pace can be fast and slow simultaneously.
Another different approach to doing business is that in a buying decision: Westerners tend to look for clear alternatives, while Easterners may examine ways to combine both options. For example, a Chinese panel may feel that a supplier who combines claims of best quality with a low price may either raise the price during the contract or fail to implement the contract. They will therefore often prefer to choose a supplier whose price is neither the cheapest nor the most expensive. In addition, a Chinese panel may avoid awarding each supplier more than one contract , in order to minimize dependence on a single supplier. Such an approach may make a Westerner think that a Chinese negotiator is being illogical, evasive or devious, when he himself believes he is being quite straightforward.
What's more, both Chinese and foreign companies will often attribute their business success to having good guanxi. The objective of developing close relationships is to build what the Chinese call guanxi (pronounced gwan shee), which are essentially social or business connections based on mutual interest and benefit in a centralized and bureaucratic state, reliance on personal contacts is often seen as the only way to get thing done. And in a place like China where the legal system is still relatively weak, the need to rely on guanxi remains strong.
Both Chinese and foreign companies will often attribute their business success to having good guanxi. But the obligations of guanxi are very real. In the wrong place, at an inappropriate time, with unsuitable people, the obligations can become a trap which is hard to escape.
What can be inferred from paragraph 2 ?
A.Westerners may establish long-term cooperation with one supplier.
B.Chinese panel tends to looking for clear alternatives.
C.Chinese negotiator is illogical.
D.Westerners are straightforward in Chinese businessmen's eyes.

[单项选择]Despite what you might think from its name, the Museum of Afghan Civilization will be the very model of a modern major museum when it opens in January. It will be housed in an angular, postmodern building, designed by France’s Yona Friedman. It will display the art of Afghanistan from prehistory to today, with works collected from all over the world. And it will have a nifty website, complete with high-definition reproductions and interactive information guides. What the museum won’t have is a front door, a parking lot, or a cafeteria. That’s because the museum is the first designed as a virtual building only.
Why put the objects in an imaginary building, instead of just creating a website full of pictures Pascale Bastide, President of the Paris-based association Afghanculture, says she hopes that hiring an architect will imbue her project (afghanculturemuseum.org) with the gravitas of a traditional museum, as well as make viewers feel as though they are actively traveling to a mu
