However, there is some difference in lifestyle between city settlers and the country people. Almost 90 percent ofthe population lives in the fast-paced cities along the coast and has little more than a passing familiarity with the desert. The major cities preserve images of colonial heritage, but on the whole the impression is modern, with new buildings reflecting the country's youth. In contrast, therural communities tend to be slow-moving and conservative. For many years, Australia was said to have "ridden on the sheep's back" , are ference to wool being the country's main money earner. However, it is nolonger dominant ( 主宰的). Much of Australia's relatively sound economy is now achieved from natural coal and wheat, and by being the largest diamond producer in the world. Newer industries such as tourism and wine making are also increasingly important. Australians are generally friendly and relaxed, with a modest sense of humor.

    Yet, contrary to wide spread belief, very few Australians have true prisoner origins. Within only one generation of the arrival of the First Fleet in 1788, Australia had become a nation of immigrants. Originally coming almost entirely from the British Isles, today one in three Australians comes from elsewhere. Australia's liberal postwar immigration policies led to a flowing of survivors from war-torn Europe. The emphasis has changed in recent years and today the majority of new immigrants are from Southeast Asia. Today Australia is a "mixture of nations" and although some racism exists, it has generally been a successful experiment and the country is reasonably proud to have one of the most harmonious multicultural communities in the world.

    A new study shows students who write notes by hand during lectures perform better on exams than those who use laptops(笔记本电脑)．

    Students are increasingly using laptops for note­taking because of speed and legibility(清晰度)．But the research has found laptop users are less able to remember and apply the concepts they have been taught.

    Researchers performed experiments that aimed to find out whether using a laptop increased the tendency to make notes “mindlessly” by taking down word for word what the professors said.

    In the first experiment，students were given either a laptop or pen and paper. They listened to the same lectures and were told to use their usual note­taking skills. Thirty minutes after the talk，they were examined on their ability to remember facts and on how well they understood concepts.

    The researchers found that laptop users took twice as many notes as those who wrote by hand. However，the typists performed worse at remembering and applying the concepts. Both groups scored similarly when it came to memorizing facts.

    The researchers' report said，“While more notes are beneficial，if the notes are taken mindlessly，as is more likely the case on a laptop，the benefit disappears.”

    In another experiment aimed at testing long­term memory，students took notes as before but were tested a week after the lecture. This time，the students who wrote notes by hand performed significantly better on the exam.

    These two experiments suggest that handwritten notes are not only better for immediate learning and understanding，but that they also lead to superior revision in the future.

    China has recently published its first artificial intelligence (AI) textbook for high school students, following a plan by central government last year to include AI courses in primary and secondary school.

    Under the joint efforts by the research center for MOOC at East Normal University and AI startup Sense Time Group, the nine-chapter textbook, named Fundamentals of Artificial Intelligence, was written by eminent scholars from well-known schools nationwide, Xinhua reported on Sunday.

    It includes the history of AI and how the technology can be applied in areas such as facial recognition, auto driving and public security.

    “The textbook focuses not only on basics of AI, also on practical use of AI in daily life,” said Chen Yukun, a professor at East China Normal University, who is also a contributor to the book. At present, about 40 high schools across the country have joined the first batch（批）of AI high education pilot program, by introducing the textbook in curriculum（全部课程）.

    “The AI sector is facing a talent shortage globally. The publication of the book is a breakthrough as it takes AI technology out of the 'ivory tower' and makes it part of high school learning,” said Lin Dahua, a professor at the Chinese University of Hong Kong.

    As early as 2016, the governments had estimated that demand for AI professionals may suddenly increase to 5 million in the coming years.

    “Many industries in the future will benefits from AI technology, so the aim of the related courses should be to let students learn the basic idea and methods of AI,” Lin said.

    China has made significant progress in technological research and development in recent years. According to a report released by US-based venture capital（风险资本）database CB Insights in March, China has for the first time surpassed the United States in equity funding（股权融资）to AI startups.

    Oct.15th was International White Cane Safety Day. You may have never heard of it, but it was a day to remember for Peng Baier, 17, of Nanjing Foreign Language School. After school that day, he visited his local Disabled Persons' Federation (残疾人联合会). He wanted to know about the sales and feedback (反馈) of his newly published book, How to Help a Disabled Person.

    Since he lives with his disabled grandparents, he understands that life can be hard for this group of people. Peng decided to write the book because he wanted to create a better life for disabled people in China.

    “Crossing the street is a big problem for them,” Peng said. “Speeding cars, people walking in a hurry, bikes on the sidewalk for the blind - accidents can happen everywhere. That's why we hardly ever see disabled people on the street, even though there are millions of disabled people in China.”

    Peng's book with pictures is easy to understand. It is a guide to the right and wrong ways to treat disabled people. The left-hand pages show the reader the right way; the right-hand pages point out mistakes that are commonly made.

    The teenager had 2,000 copies of his book printed. With the help of the Disabled Persons' Federation, he gave them to the disabled community.

    “The book is bilingual, so foreigners can also use it,” said Peng.

    Peng put great effort into the book. For example, he interviewed many disabled people to get first hand materials. He also studied textbooks from different schools for the disabled. Peng finally completed his handbook, but he still had the problem of getting it printed.

    How does a high school student raise money needed for that?

    With a smile, Peng said how he went about it. “I visited three local companies, dressed up in a suit and tie. I was lucky. The companies were warm-hearted and willing to give me a hand.”

    When the telephone rings late at night, most women guess it must be one of only four or five people calling. A sister? Maybe. An emergency? Possibly. A mother? Probably not at that time of night. Much more probably it is a close female friend calling to tell you that she is heartbroken because she has split up with her boyfriend again or perhaps simply that a good movie has just started on TV.

    At a time when families are spread far and wide and marriages often end in divorce, friendships are becoming more and more important. Erika, a 32-year-old lawyer, is strengthened by her ten year friendship with her married friend Jane. "I was very sick one night, so I called Jane at about 3：00 a. m. to talk about it," she says. "She was very supportive and even came over to take me to the doctor's."

    As American TV shows like Friends have become more popular, many of us are beginning to see the value of such friendships.TV shows like this tell us that our romantic relationships may not last, but we need to keep in touch with our close friends if we want to survive.

    With Erika's family 200 miles away, it is Jane who keeps a spare set of keys to Erika's apartment and waters her plants whenever she is away. "Having Jane around gives me a certain amount of freedom. It is not the kind of thing that you could ask anyone to do, but she knows I would do the same for her. "Jane, who may move to a different city soon, is worried about leaving such a support system of friends. "My friends have more to do with my life than my parents and, therefore, I don't have to spend a lot of time explaining things to them. Friends are more up to date with what is happening."
