Life is comprised emotion and sense. When we were babies we reached the pinnacle(顶峰) of emotion. At that time we asked for everything that we wanted, cried as we were uncomfortable, laughed as we were happy and released our emotions day and night. When we grow up we find that if we want to live in a cozier environment we must be sensible enough to deal with our emotions and relationships. Our world is based on sense and beautified by emotion.

    Sense is the base of life; it builds up the structure of life, and helps us see the real world. And emotion is the invaluable element of life. It adds colorful paint to our life. Lacking sense we may lose the guiding light and lacking emotion we may lose the value of life.

    We admire Da Vinci's Mona Lisa, we are attracted by Michelangelo's The Creation of Man, and we are carried away by Monet's Lotus. Shakespeare's Romeo and Juliet may bring us tears, Victor Hugo's poems can make a maid's love revive, and Jane Austin's stories arouse our dream of holding a party of ladies and gentlemen as an England beauty in the countryside. All of them are people who deserve our respect and showed us sentimental emotion: love, hatred, betrayal, loyalty and so on. They made their works full of emotion, shocked our nerves, and evoked our passions. Somebody may have found their destiny in these works, and surely they influence people time after time. But in fact, though these people or their works have the power to control our mental world, we don't choose them to be our President or Prime Minister. We cannot deny the fact that our world is based on sense and ration. Mark Twain once said that the passion of friendship is so sweet, steady and royal and enduring a nature that it will last through a whole lifetime if neither of the two friends asks the other to lend money.

    Emotion is our nature and sense gives us an eye to live in reality. Only sense makes Jack a dull boy; emotional moments give us vigor and enthusiasm to live and color our life.

    The first Ferris wheel was built for the 1893 World's Columbian Exposition in Chicago. The people who planned the fair were looking for an attraction that would bring people to Chicago. The Eiffel Tower had been a great success for the fair in Pairs in 1889, and they wanted something like that.

    George Ferris handed in drawings of a giant wheel that people could ride on. At first everyone laughed at his strange idea. But Mr. Ferris didn't give up, and finally the idea was accepted. The ride opened in June of 1893.

    That first wheel had thirty six enclosed cars, each holding sixty passengers. When filled it carried 2,160 people. During that summer in Chicago one and a half million people rode the Ferris wheel, which was named after Ferris. Six platforms were used to pick up and drop off passengers. Each ride was two full turns of the wheel. On the first turn, it made six stops for loading. Then the second turn was a nonstop nine-minute ride. Each car had five large glass windows in front and in back, giving everyone a great view of Chicago and Lake Michigan.

    After the fair the ride was moved to a nearby amusement park built especially to show off the wheel. In 1904 it was moved again—this time to St. Louis for the Louisiana Purchase Exposition. After the fair in St. Louis closed, the wheel stood unused. In 1906 it was finally sold to a company for scrap(废弃材料）metal. It took 200 pounds of dynamite to bring it down.

    Fortunately a Chicago bridge builder, W. E. Sullivan, figured out how to make a smaller Ferris wheel that could easily be taken apart and put together. In 1906 he started the company that still makes many of the Ferris wheels used today.

    But whenever you ride one remember that it all began with George Ferris' very strange idea.

    Tang Dynasty poets sang for about three centuries in different tones. There were many famous poets living in the Tang period such as Li Bai, Du Fu, Bai Juyi and Li Shangyin. Poems of the Tang Dynasty edited in the Qing Dynasty is a collection of about 48,900 poems that were written by over 2,200 poets. But it didn't cover all the poems of the Tang Dynasty.

    During the Tang Dynasty, poems were recited when lovers walked under the moonlight. Poems were also recited when soldiers fought on the battlefield. People recited them in the open air or at temple fairs.

    In the Tang Dynasty scholars had to be poets. Their readers were not only people of high social position but also common people. Poets recited poems; women singers sang poems and other ranks of people, including old women and children, read Tang poems. This atmosphere affected foreigners who visited the country at that time. As a result, Tang poetry was introduced to some adjacent countries, like Japan and Vietnam.

    Tang poetry is a most brilliant page in the history of ancient Chinese literature. It's a miracle in the cultural history of mankind. The Tang Dynasty was a powerful empire with a vast territory. It inherited Chinese civilization that went back to ancient times, and was combined with the best of other cultures and adopted the benefits of other nations in the world. Tang poetry wasn't the only spiritual wealth created by the Tang Dynasty people. Philosophy and religion, handwriting and painting and music and dance all gained new peaks of development. Tang poetry, however, was the jewel in the crown and its greatest achievement.

    From self-driving cars to carebots for elderly people, rapid development in technology has long represented a possible threat to many jobs normally performed by people. But experts now believe that almost 50 percent of occupations existing today will be completely unnecessary by 2025 as artificial intelligence continues to change businesses.

    "The next fifteen years will see a revolution in how we work, and a revolution will necessarily take place in how we plan and think about workplaces," said Peter Andrew, Director of Workplace Strategy for CBRE Asia Pacific.

    A growing number of jobs in the future will require creative intelligence, social skills and the ability to use artificial intelligence.

    The report is based on interviews with 200 experts, business leaders and young people from Asia Pacific, Europe and North America. It shows that in the US technology already destroys more jobs than it creates.

    But the report states: "Losing occupations does not necessarily mean losing jobs — just changing what people do." Growth in new jobs could occur as much, according to the research.

    "The growth of 20 to 40 person companies that have the speed and technological know-how will directly challenge big companies," it states.

    A 2014 report by Pew Research found 52 percent of experts in artificial intelligence and robotics were optimistic about the future and believed there would still be enough jobs in the next few years. The optimists pictured "a future in which robots do not take the place of more jobs than they create," according to Aaron Smith, the report's co-author.

    "Technology will continue to affect jobs, but more jobs seem likely to be created. Although there have always been unemployed people, when we reached a few billion people there were billions of jobs. There is no shortage of things that need to be done and that will not change," Microsoft's Jonathan Grudin told researchers.

    It was a shock and a painful lesson for many people when the police announced the cause of a bus accident in Chongqing on Oct 28. Video footage (片段) from inside the bus suggested that after a passenger missed her stop and asked the driver to stop, but he refused. She began hitting him over the head with her cell phone. During the conflict, the driver lost control of the bus and it jumped into the Yangtze River, causing 15 deaths.

    Zheng Chuankai, a lawyer in Beijing, said the accident showed that it was important that those who cause danger to public safety face severe punishment. Such attacks are inhuman but common. In fact, it is not rare to hear of passengers attacking bus drivers in China. This month, a local court in Shenyang, Liaoning province, sentenced three people to up to three years in prison for endangering public safety by distracting bus drivers, Xinhua reported. “Passengers who interfere (妨碍) with bus drivers are endangering public safety, which is equal to serious crimes like arson (纵火) and poisoning.” Liu Changsong，a Beijing lawyer, told the Global Times.

To prevent similar cases from happening, many Chinese cities have taken measures to keep bus drivers safe. Dozens of cities including Beijing, Xi'an, Wuhan, Changsha and Nanning have plans to add safety fences to buses to protect drivers from any interference by passengers.

    The bus operator in Quanzhou, Fujian Province, has invited psychologists to teach drivers how to manage their emotions when facing an angry passenger. These measures are necessary, but they are not enough.

    “Public security is closely connected with social morality (道德). People should obey the law, be more self-disciplined and sensible.”

    Many countries have introduced measures to deal with the problem of violence against bus drivers. On every bus in the US state of New Jersey, a sign on the back of the driver's seat warns passengers that anyone attacking a driver can be fined or put into prison.

    In London, the local government has launched a program to train drivers to deal with angry passengers and avoid potential conflicts.

    Put an ice cube from your fridge into a glass of water. You have a piece of string (线) 10 centimeters long. The problem is to take out that piece of ice with the help of the string. But you must not touch the ice with your fingers.

    You may ask your friends to try to do that when you are having dinner together. There is a saltcellar on the table. You must use salt when you carry out this experiment.

    First you put the string across the piece of ice. Then put some salt on the ice. Salt makes ice melt (融化). The ice round the string will begin to melt. But when it melts, it will lose heat. The cold ice cube will make the salt water freeze again.

    After a minute or two you may raise the piece of string and with it you will raise your piece of ice!

    This experiment can be very useful to you. If, for example, there is ice near the door of your house, you must use very much salt to melt all the ice. If you don't put enough salt, the water will freeze again.
