　　Mexico City is truly one of the most amazing cities in the world with a mixture of both the old and new world．From the moment your plane starts to descend into this vast city, you know that your trip will be quite an adventure．

　　Once in your taxi and the moment you leave the airport, you are amazed at the large amount of slow traffic．The volume of the traffic can be stressful to some．

　　The "Paseo de la Reforma(改革大道)", running southwest across the city, is one of the major tourist and business areas in Mexico City with many high quality hotels only walking distance from great restaurants and other tourist attractions．The only problem you will have is trying to see all of these sites during your vacation time．

　　One of the most popular attractions in this area is the National Museum of Anthropology along the northwest part of the street．There are thousands of artifacts on display showing the history of the area and numerous items found from the many Aztec sites in the area．Walking southwest from the museum, you will soon reach the Mexico City Zoo, which is a great place to spend an afternoon．

　　Across the street from the museum is the Chapultepec Castle, once an important site in the Mexican-American war．It's also a good idea to take the train up the hill to where the castle is located as the hill is steep．It's important to keep in mind that Mexico City is over 7,000 feet above sea level and some feel it difficult to breathe when walking．

　　You can take a taxi to the Coyoacan market during the evening on a weekend．It's a great place to get some cheap souvenirs to bring back home and to enjoy some traditional Mexican cuisine．However, you must be careful where you eat and that the meat is well cooked．

　　Mr Black was the manager of a hotel in Atlanta．One weekend all of the hotels were full because of a large business meeting being held in the city．On Sunday night, three men came into Mr Black's hotel and asked for rooms．Mr Black told them that there were no more rooms available．The men didn't know what to do because they had no place to stay in．

　　Mr Black wanted to help them．He remembered that there was an empty room at the far end of the first floor－Room 112．It was a very small room, and had rarely been used as a guest room before．So, be asked the three men if they would mind sharing that small room．They replied that they would be very much satisfied so long as there was a room for them to stay in for the night．

　　Mr Black then told them that the room would cost them ＄ 30 in total．On hearing this, each of the three men gave Mr Black ＄ 10 before they left for their room．

　　However, Mr Black soon began to think that ＄ 30 was really too much for that small room．He called his assistant over and said, “Here is ＄ 5．Give it back to the three men in Room 112．Each of them paid me ＄10．That's too much．”

　　The assistant took the money．While he was on the way to that small room, he thought, “How can three men divide ＄ 5?I'll give each of them only ＄ 1 and keep the ＄ 2 left to myself．The men will be happy to get anything back, and I can also make some money that way．After all, Mr Black will never know anything about it．” So, the assistant returned only＄1 to each of the three men．

　　Each man had first paid＄10．After the assistant returned＄1 to him, each man had actually paid only＄9．There were three men．＄9×3＝＄27．The assistant kept ＄2．＄27＋＄2＝＄29．Where is the missing dollar?
