　　Passage 12

　　Traveling to all countries of the world gets easier and easier, but how well do we know and u  1    each other? Here is a simple test. Imagine(设想) you will hold a m   2    at four o'clock, what time should you e   3    your foreign business friends to come? If they are German, they will a  4    on time. If they are American, they'll probably be fifteen minutes early. If they are British, they'll be fifteen minutes late.

　　The British seemed to think since the English l  5   was widely used in the world, what they did was certain to be widely understood. Very soon they f  6   they were completely(完全地) wrong. For e   7    , the British are happy to have a business lunch and discuss business matters with a drink during the meal; the Japanese p   8    not to work while eating. Lunch is a time for them to relax and get to know e   9    other, and they don't drink at lunch. The Germans like to talk about business b   10    dinner; the French like to eat first and talk afterwards. They have to be well fed and watered before they discuss anything.
