Though there are about 400 languages from all over the world that are in danger of disappearing completely，Zoque-Ayapaneco，a native Mexican language is considered the most likely to become extinct，because the only two people in the world that speak it fluently do not talk to each other!

    And，it's not because they live in different countries，states or even villages. In fact，Manuel Segovia and Isidro Velazquez，both in their 70s，live within 500 yards of each other，in the village of Ayapa in the Southern Mexican State of Tabasco. They，however，refuse to communicate because they simply don't have much in common. Segovia is apparently a little frank in nature while Velazquez is described as shy.

    Segovia was at least able to talk in Zoque-Ayapanece with his brother until he passed away about 12 years ago，and still manages to practice it with his family，especially his son Manuel，who for the last five years has been trying to learn it and hopes to become fluent enough to teach it to the next generation. Velazquez on the other hand，has not been heard speaking in the language with anybody.

    The two men say the language used to be widely spoken in the village，but the younger generation refused to learn it for fear of being laughed at，and it therefore began to die a slow death，as the elders passed away.

    Unless the two men get their acts together，the only way to hear the language will be to either listen to Manuel's not-so-fluent statement or see them talk in a documentary entitled “Lengua Muerta” (Dead Language) that is being filmed to capture Zoque Ayapaneco and 364 other native Mexican languages that are in a similar state.

    We sure hope Segovia and Velazquez soon find something common to talk about. Maybe the fact is that the language is dying and that they should start encouraging and teaching the next generation together.

    Most buildings are built to stand up straight, but these look as if they might fall over!

The church tower of Suurhusen

    Built in 1450, the 27-meter-high church tower lies in Suurhusen, Germany. It was built in wet land on foundations of oak tree trunks (树干). When the land was drained (排水) later, the wood broke down, causing one side of the tower to be a little lower than the other. In 1975, the tower became a real hazard and people were not allowed to enter until the foundations were made strong again. The lean (倾斜) of the tower is now about five degrees.

The Leaning Tower of Pisa

    The work of building the tower began in 1173, and was finally completed in 1372. In fact, it began to lean after just a couple of floors were built. And this condition continued in the centuries after its completion. The tower was finally closed to the public in 1990 after people failed to stabilize (使稳固) its foundations. In 2001, it was reopened after engineers removed soil from underneath its raised side. Now it leans just an angle of 3.97 degrees.

Capital Gate of Abu Dhabi

    Completed in 2011, the Capital Gate tower in Abu Dhabi was designed to lean eighteen degrees. The building stands next to the Abu Dhabi National Exhibition Centre and contains, among other things, a fine hotel with wonderful views of the harbour. Also known as the leaning tower of Abu Dhabi, the tower is one of the tallest buildings in the city.

Big Ben of London

    The building leans 0.26 degrees to the northwest. This is mainly caused by the engineering projects that have been carried out in the ground below it since the late 1800s. The tower, which has been continuously open since it was completed in 1858, has nowhere near the lean of the Tower of Pisa and is still completely safe to enter.

    My grandparents believed that you were either honest or you were not. They had a simple saying hanging on their living-room wall: “Life is like a field of newly fallen snow. Where I choose to walk every step will show.” They didn't have to talk about it; they showed this truth by the way they lived.

    They understood that honesty is an inner(内部的) standard for judging your behavior. Unfortunately, honesty is in short supply today. But it is the real bottom line in every area of society and a discipline (自制能力) we must demand of ourselves.

    There's a story told about a surgical nurse's first day on the medical team at a well-known hospital. She was responsible(负责) for all surgical instruments and materials during an operation. At the end of the operation, the nurse said to the doctor, “ You've only removed 11 sponges（海绵）, and we used 12. We need to find the last one.”

     “I removed them all,” the doctor assured her. “ No, you didn't , sir,” insisted the nurse. “ Think of the patient.”

    Smiling, the doctor lifted his foot and showed the nurse the twelfth sponge.

    So when you know you're right, you can't yield. Don't be afraid of those who might have a better idea or who might even be more intelligent than you are.

    Self-respect and a clear awareness (意识)of right and wrong are powerful parts of honesty and are the basis for enriching your relationships with others. Honesty means you do what you do because it's right and not just fashionable or politically correct. A life of principle, of not easily yielding, will always take you forward. My grandparents taught me that.
