Dictionaries are not closed books. There is still plenty of room for more words in these great vocabulary authorities.

    Dictionaries are not closed books. There is still plenty of room for more words in these great vocabulary authorities. New words are continually being created and added to our language. And many of today's word experts can credit a famous mathematician with the creation of the method by which they develop many new words. The mathematician was an Englishman named Charles L. Dodgson. In addition to working with figures, Dodgson wrote books. His imaginative stories and poems have made Dodgson beloved to generations of readers. We know him, however, not by the name of Dodgson but by his pen name, Lewis Carroll.

    Lewis Carroll has delighted countless readers, young and old, with Alice in Wonderland, Through the Looking Glass, and numerous poems. In these works, Carroll developed dozens of nonsensical words such as "chortle" and "galumph". Many of these words are combined naturally with more common words in the English language. Carroll referred to his made-up words as "portmanteau" words, named after a kind of leather suitcase that opens into two compartments. The name was well suited, because most of Carroll's words had two compartments. Rather than being entirely fabricated（虚构）, they were usually made from the combined parts of two different words. A "snark", for example, clearly came from a snake and a shark.

    Although Carroll died long ago, his technique continues to be used today. We clearly see his influence in such words as smog, brunch, and guesstimate.

    Worldwide, the most people willing to return your mobile phone if you've lost it are to be found in Slovenia, and the fewest in Malaysia. This finding is the result of an interesting study in 32 of the world's largest cities. Altogether, researchers 'lost' 960 new mobile phones. They got back 654 of them，or 68 percent. Prague came in at number eight. There, 23 out of 30 people who were willing to return the mobile phone.

    It wasn't a traditional study. Two researchers carefully chose different places such as areas with high crime(犯罪)and busy downtown shopping areas, to “lose” the phones. When one of the researchers dropped a phone, the other would keep watching from a distance. The honest finders tried their best to find the owner with the help of the address book in the phone. They were told why the study was done and asked why they acted the way they did.

    It was found that the busier the place where the researchers dropped the phone, the greater the chance of it being returned. Another interesting finding was that women were generally more likely than men to return the phone. Researchers also found that most people still have a sense of honesty. “Crime is simply not good behavior (行为), ”said an expert. “People want to trust others, and want to be trusted.”

    One of the most important aspects of an image is color. People are very sensitive to color, and different colors have different on people.

    In general, red is an exciting color, which creates an image of action, energy danger. Red is also the most frequently used color in flags. Eighty percent of the world's flags contain red. A study in Germany showed that football teams wearing red are more successful. Blue is a very calm color. Business executives usually wear dark blue suits. Blue is also a peaceful color. The flag of the United Nations is light blue. Yellow is associated with openness and freedom. Green is a very relaxing color. Surgeons nowadays wear green, because it's less tiring than white. Black creates an image of power and authority. It can also be a very threatening color. Gangsters and vampires often wear black, white is a pure and strong color. This is one reason why doctors wear white coats. We trust them more. Grey is a very anonymouscolor. People wearing grey don't want other people to notice them. Brown is the opposite of black. It's warm and friendly, while black is threatening

    There was a lot of news related to artificial intelligence, or AI, and machine learning. Among the stories were two dealing with direct competitions between humans and machines.

    In one competition, machines that used AI performed better than human beings in a high-level reading test. Two natural language processing tools beat human in the experiment. One of the tools was built by the American technology company Microsoft. The other was created by Chinese online seller Alibaba Group.

    In another competition, a computer took on humans in live, public debates.

    The event demonstrated how AI-powered computers are increasingly being developed to think ' and sound like humans. The organizer of the debates, U. S. technology company IBM, announced split results. It said a majority of those watching said they felt the machine had done more to improve their knowledge of the subject. But, the human got more praise for communicating their ideas.

    This year, we also explored the many ways AI and machine learning are now being used. For example, some U. S. judges use machine learning systems to help them decide when, and for how long, criminals should be jailed. The system uses computers to examine data from thousands of court cases.

    One fast-growing area of AI is facial recognition, which is increasingly being used for security purposes. Recently, Atlanta's Hartsfield-Jackson airport became the first in the U. S. to permit passengers to use facial recognition technology to get on flights. A Chinese company showed off an AI system it developed to recognize individuals by body shape and walking movements. The system is already being used by Chinese police in Beijing and Shanghai.

    In addition, machine learning was used during 2018 to predict results of the World Cup soccer competition. The technology also created artwork that sold for a large amount of money. And it is being used to help farmer save time and money, while reducing environment-harming chemicals. Other technology systems are being used to follow farm animals and wildlife to collect information on their activities.

    Over the past 40 years, China has helped more than 700 million rural residents out of being poor, and the poverty rate -- the proportion of people living below the Chinese poverty line -- had fallen among the rural population from 97.5 percent in 1978 to 3.1 percent at the end of 2017, official figures shows. China's achievements in poverty alleviation (扶贫) made the world look at China with admiration.

    "For me, it is unbelievable that over 40 years, that is, over the course of one working lifetime, China has gone from one of the poorest countries in the world to one that is about to eliminate(消除) absolute poverty," said Craig Allen, president of the US-China Business Council.

    Varaprasad Sekhar Dolla, a professor of Chinese studies at India's Jawaharlal Nehru University, also spoke highly of China's achievements in poverty reduction. "If global poverty came down greatly in the last three or four decades, it's partly because of the Chinese contribution to reducing poverty within its own national boundaries," said the Indian scholar.

    In the eyes of Khairy Tourk, a professor of economics with the Stuart School of Business at the Illinois Institute of Technology in Chicago, "many countries look up to China to learn from its experience." "The Chinese experience is based on building a modern infrastructure (基础设施) and then on setting up special economic zones that would help underdeveloped countries to become more industrial," he added.

    In the government work report delivered at the opening of the annual NPC session (全国人大会议) on March 5, China promises to reduce its population of rural poor by over 10 million this year.

When you are going to visit Beijing, it's likely that you'll want to visit the Tiananmen Square.
