    Canada Geese are large blue and white birds. When autumn comes, they have to fly south where the weather is warmer. The winters are so cold in Canada that the birds will die if they stay there.

    Last spring, Bill Lishman found sixteen young Canada Geese on his farm. They had lost their parents. Bill thought, “These young birds won't know what to do in the autumn.” He had a small plane and he decided to teach the birds to fly by following him. All through the summer, he went on short trips in his plane and the young geese flew after him.

    When the cold weather arrived in the autumn, Bill flew to Virginia in the United States--600 miles south of his home in Canada. The geese followed him all the way. Bill left the geese in Virginia and he returned home. This spring, Bill was waiting for the birds to come back. They didn't arrive, so Bill flew to Virginia to get them. He looked for them for two weeks but he couldn't find them. When he arrived back home, he found the geese waiting for him. They had found their way home without him!

    With the development of Internet, relative services are developed in the form of websites or apps on phones too. Here introduces you Airbnb and Uber.

    1 Airbnb (air Bed and Breakfast)

People can offer or rent rooms for a short time on Airbnb website or its app on smart phones. The cost is usually cheaper than that of hotels. Travelers can book rooms with special activities such as enjoying local music, art and food.

    Airbnb was founded in August 2008, and now it has over two million listings for travelers to choose in the world. The idea of Airbnb, as its symbol shows, is about home and trust.

    2 Uber

    Uber is a ride sharing and taxi app for fast rides in minutes—day or night. It was founded as Uber Cab in March 2009. The Uber app can send an order to the nearest Uber driver, asking him to the location soon. Users can track the car on their smart phones, so they can know when it will arrive.

In August 2016, Uber service was provided in 507 cities and over 66 countries. However, in China, its operation was acquired by Didi in July 2016. The website Bloomberg View said in July 2015 that Uber makes it easier for people to get a taxi.

    Different weather makes people feel different. It influences health, intelligence (智力) and feelings.

    In August, it is very hot and wet in the southern part of the United States. People there have heart trouble and other kinds of health problems during this month. In the Northeast and the Middle West, it is very hot at some times and very cold at other times. People in these states have more heart trouble after the weather changes in February or March.

    The weather can also influence intelligence. For example, in a scientific report, IQ (智商) of a group of students was very high when a very strong wind came, but after the strong wind, their IQ was 10% below. The wind can help people have more intelligence. Very hot weather, on the other hand (另一方面), can make it lower. Students in many schools of the United States often get worse on exams in the hot months of the year (July and August).

    Weather also has a strong influence on people's feelings. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel unhappy during cold weather. But fat people may have a hard time in hot summer. At about 18 ℃, people become stronger.

    Low air pressure (气压) may make people forgetful People leave more bags on buses and in shops on low-pressure days. There is a "good weather" for health. People feel best at a temperature of about I8℃.

    Are you feeling sad, tired, forgetful, or unhappy today? It may be the weather's problem.

    Are you shy? If you are, you are not alone. In fact, close to 50 percent of people are shy. Almost 80 percent of people feel shy at some point in their lives. These days, shyness is becoming more and more common. Now, scientists are trying to understand shyness. They have some interesting ideas about why people are shy.

    Is it possible to be born shy? Many scientists say yes. They say 15 to 20 percent of babies behave shyly. These babies are a little quieter and more watchful than other babies. Interestingly, these shy babies usually have shy parents. As a result, scientists think that some shyness is genetic.

    Family size might cause people to be shy as well. Scientists at Harvard University studied shy children. They found that 66 percent of them had older brothers and sisters. The scientists said that these children were often bullied(欺侮) by their older brothers and sisters. As a result, they became shy. At the same time, children with no brothers and sisters may be shy as well. Growing up alone, they often play by themselves. They are not able to learn the same social skills as children from big families.

    You may also be shy because of where you were born. When scientists studied shyness in different countries, they found surprising differences. In Japan, most people said they were shy. But in Israel, only one of three people said so. What explains the difference? One scientist says the Japanese and Israelis have different opinions of failure. In Japan, when people do not succeed, they feel bad about themselves. They blame (责备) themselves for their failure. In Israel, the opposite is true. Israelis often blame failure on outside reasons, such as family, teachers, friends, or bad luck. In Israel, freedom of opinion and risk-taking are strongly supported. This may be why Israelis worry less about failure and are less shy.

    For shy people, it can be difficult to make friends, speak in class, and even get a good job. But scientists say you can get over your shyness. They suggest trying new things and practicing conversation. And don't forget—if you are shy, you are not the only one.
