Different countries have different customs. When you travel to another countries，please follow their customs，just as the saying goes，“             .”
Very often people who travel to the United States forget to tip（付小费）.It is usual to tip porters who help carry your bags，taxi drivers and waiters. Waiters expect to get a 15% tip on the cost of your meal. Taxi drivers expect about the same amount.
In England，make sure to stand in line even if there are only two of you. It’s important to respect lines there. It’s a good idea to talk about the weather. It’s a favorite subject of conversation with the British.
In Spain，it’s a good idea to have a light meal in the afternoon if someone invites you for dinner. People have dinner very late，and restaurants do not generally open until after 9 pm.
In Arab countries，men kiss one another on the cheek（脸颊）. Your host may welcome you with a kiss on both cheeks. It is polite for you to do the same.
In Japan，people usually give personal or business cards to each other when they meet for the first time. When a person gives you a card，don’t put it into your pocket right away. The person expects you to read it.
Don’t forget to be careful of your body language to express something In conversation. A kind of body language that is acceptable in one culture may be impolite in another.

He put a wide-mouth jar (罐子) on the table. Then he    2  some rocks and carefully placed them into the jar, one at a time. When  3  rocks would fit inside, he   4  , “Is this jar full?”
Everyone in class shouted, “Yes.” “Really?” The teacher pulled out a bag of small stones. He put   5  small stones in and shook the jar. The small stones went   6  into the spaces between the big rocks. He then asked the group   7  , “Is this jar full?”
“Probably not,” one of them answered. “Good!” the teacher replied. He brought out a box of sand and   8  some sand into the jar and it went between the rocks and small stones. Again he asked the   9  question, “Is this jar full?
“No,” the class shouted. Once more the teacher said, “Good.” He poured a cup of water into the jar   10  it was full. The he asked, “What is the point here?” One student   11  his hand and said, “The point is that if you try really hard, you can   12  put more things in.”
“No,” the teacher replied, “that’s not the  13  . What I want to tell you is that if you don’t put the big rocks in first, you will never get others in at all.   14  are the ‘big rocks’ in your life? Time with your friends, your education or your dreams? Remember to put the  15  in first, or you’ll never get others in at all.?”
