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.

    Travelling to China is like travelling to another world. Its many famous beautiful places will make you lose yourself in them. However, it is usually not enough for a traveller only to visit these nice places. If you have time to see the local people, talk with them and even have dinner with a local family, it would be a wonderful experience, to know more about the local people's life style at home in China.

    New Hope Travel Agency will arrange (安排) a family visit to Xi'an, an ancient historic city in China. We especially have chosen typical local families to host this activity in which you can see the true living style of Chinese people. Most of the hosts retired (退休) at home, so they are happy to see visitors from different countries to come to their homes.

    Not only can we arrange to visit the local family but we can arrange to taste the true home cooked dishes. Our tour guide will ask you for advice about the food you want to eat. Just enjoy the locally cooked dishes. It'll be quite a different and exciting experience.

    Our agency also provides a good opportunity for you to learn to cook Chinese food. We have a general cooking class in the local family. If you'd like to learn to cook one or two Chinese dishes, please go to our Chinese Food Cooking Class to choose your favorite dishes.

    Don't wait. Welcome to China.

    A study showed that the experiences children have in their first few years are important. These experiences affect the development of the brain. When children receive more attention, they often have higher IQs. Babies receive information when they see, hear and feel things, which makes connections between different parts of the brain. There are a hundred trillion (万亿) connections in the brain of a three-year-old child.

    Researcher Judit Gervain tested how good newborns are at distinguishing different sound patterns. Her researchers produced images of the brains of babies as they heard different sound patterns. For example, one order was mu-ba-ba. This is the pattern "A-B-B". Another order was mu-ba-ge. This is the pattern "A-B-C". The images showed that the part of the brain responsible for speech was more active during the "A-B-B" pattern. This shows that babies can tell the difference between different patterns. They also were sensitive to where it occurred in the order.

    Gervain is excited by these findings because the order of sounds is the building block of words and grammar. "Position is key to language," she says. "If something is at the beginning or at the end, it makes a big difference: 'John caught the bear.' is very different from 'The bear caught John.' "

    Researchers led by scientist Patricia Kuhl have found that language delivered by televisions, audio books, the Internet, or smartphones－no matter how educational－doesn't appear to be enough for children's brain development. They carried out a study of nine-month-old American babies. They expected the first group who'd watched videos in Chinese to show the same kind of learning as the second group who were brought face-to-face with the same sounds. Instead they found a huge difference. The babies in the second group were able to distinguish between similar Chinese sounds as well as native listeners. But the other babies－regardless of whether they had watched the video or listened to the audio－learned nothing.

    Forty-three years ago, a man took a "small step" on the moon and brought mankind a "giant leap" forward. As the first person to walk on the moon, American astronaut Neil Armstrong is a man whose name will be remembered for generations to come.

    But being the first is never easy. With so many unknowns about space at that time, Armstrong himself was astonished that Apollo 11 actually worked. He thought he and his partners had merely a 50 percent chance of a successful landing back in 1969.

    It was tough indeed. When the module (登月舱) was approaching the moon's surface, the computer wanted to rest them on a steep slope covered with rocks, but Armstrong realized it was an unsafe place to stop.

    As a last minute decision, he safely landed the module by himself. When they finally touched the ground, "there was something like 20 seconds of fuel left," he said in an interview earlier this year.

    Unfortunately, some people doubted his visit to the moon, saying it was faked. But Armstrong responded with a chuckle (轻声笑), saying: "It was never a concern to me because I knew one day, somebody was going to go fly back up there and pick up that camera I left."

    For all his global fame, Neil Armstrong is a remarkably modest man. He rarely gave interviews and didn't like talking about his achievement. He stopped giving his signatures when he found that people sold them for thousands of dollars.

    "I guess we all like to be recognized not for one piece of fireworks but for the ledger (记账簿) of our daily work," Armstrong said in a CBS interview in 2005. When asked how he felt knowing his footprints would be likely to stay on the moon's surface for thousands of years, he said: "I kind of hope that somebody goes up there one of these days and cleans them up."

    Armstrong passed away last month at the age of 82, but he will be memorized. "The next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink (眨眼示意)," his family said to Reuters.

Humans' voice sounds more pleasant than that of primates（灵长类动物）because we don't have vocal membranes （声带膜）, a new study suggests.

Humans have vocal cords（声带）, muscles in the top of the throat, which vibrate（振动）to produce sound. That unique part helps people control their voices well enough to produce sounds that form spoken language. However, unlike all the other studied primates, humans don't have vocal membranes.

To find out how vocal membranes affected spoken sounds, a team from Kyoto University took throats from monkeys that had died of natural causes and put the parts into devices, pushing air through the throats to see how the vocal cords and membranes would react. In the experiment, the researchers found that their vocal membranes and vocal cords vibrated together.

Researchers said these vocal membranes make it harder for other primates to control the voices they make. Without these membranes, humans vocal source is more balanced, allowing better voice control and production of long and balanced voices. A key thing that distinguishes human speech from animal sounds is our control over the sounds we make.

In humans, that sort of unpleasant voices can happen when we put extreme amounts of pressure on our voice, like baby crying and adult screaming. But those are rare cases. Researchers also said that our mouths and tongues could help control the voices. They are the basis of human languages.
