NANJING, Nov. 4 (Xinhua) — Xi Jinping and Ma Ying-jeou will shake hands in their historic meeting scheduled in Singapore on Saturday, head of the Taiwan Affairs Office of the State Council said on Wednesday.

    The two-part meeting includes one session open to the media and another behind closed doors, said Zhang Zhijun, who is also head of the Taiwan Work Office of the Communist Party of China (CPC) Central Committee, when interviewed at the Zijinshan Summit for Entrepreneurs across the Taiwan Strait.

    According to Zhang, Xi and Ma, as "leaders of the two sides" of the Taiwan Strait, will exchange views during the closed-door meeting.

    After the meeting, press conferences will be held by both sides. Later, the two leaders are expected to attend a dinner, said Zhang.

    Zhang said the meeting will lift cross-Strait communication to a new high.

    The landmark meeting is a breakthrough in face-to-face exchange and communication between the leaders across the Taiwan Strait after the relationship became strained following the events of 1949.

    Zhang said the meeting will improve mutual trust and allow for an exchange of opinions on handling the cross-Strait ties.

    In addition, the meeting will help strengthen the 1992 Consensus(共识), which was reached in talks between the two sides in 1992 and recognizes the one-China principle, and safeguards the peaceful development of cross-Strait ties, according to Zhang.

    Zhang added that the scheduled meeting will also benefit regional peace and stability.

    Also at Wednesday's summit, Chiang Pin-kung, former chairman of the Taiwan-based Straits Exchange Foundation, hailed the upcoming meeting between the two leaders as a milestone for cross-Strait ties.

    Chiang told the media that he believed the meeting will give a boost to the peaceful development of cross-Strait ties.

    Energy goes from one plant or animal to another. A food chain shows how this energy moves. Each time an animal gets eaten, its energy is passed onto the animal that eats it. The food chain is very important because it keeps the balance of nature. If one part of the food chain disappears, it can affect all the other plants and animals. Any threat to the food chain is a threat to the environment's biodiversit(生物多样性). The food chain helps keep animal populations in balance. However, if something happens to increase or decrease one of the links in the food chain, that balance is broken. If one animal becomes endangered, it puts all the animals above it at risk.

    Some of the threats are natural, such as wildfires, hurricanes, tornados, floods and so on. But the biggest threats to the food chain come from you and me. These threats include overhunting, overfishing, logging, farming, development, pollution, etc. The food chain is endangered anywhere humans have had an effect on the natural environment.

    A recent study shows that the overfishing of large sharks is damaging the food chain along the US Atlantic coast. Canadian and American scientists say sharks are being killed in great numbers for their meat and fins(鳍). Now, not enough sharks are around to eat the cownose(牛鼻) ray. The ray's population has increased and they have eaten up the shellfish to the point where it has hurt commercial(商业的) fishing.

    Many of us disturb the natural environment in our own backyards. It's up to us to take care of the environment and try not to disrupt the natural food chain. If we don't act responsibly, animals will start disappearing.

    In Western society, especially in the English-speaking world, the chance for young people to see the other countries and experience life is considered important. Many young people, when they finish school at the age of 18, take a gap year before they go to university.

    Parents often want their children to grow up a little and see what the real world is like when they finish school. Although they are worried about their safety, many think that the advantages of independence and experience are worth the worries. Children are encouraged to be brave, independent and to explore the world on their own or with friends.

    Young people also want to experience freedom and see what life is like on the other side. This other side could be the other side of the world or just the other side of life. For example, if they have a rich life, they may want to see how people in poor areas live.

    A gap year after school is also an important chance for young people to spend time thinking about what they want to do with their lives. A little bit of growing up and experience will help them make their important career decisions, especially when they are unsure about what they want to study.

    Another reason for going straight after school is to get a break from studying before they start the next few years of university. So anywhere you travel in the world, you will meet young European people exploring the world.

    So much of the world has been travelled and explored. The young people are now looking for more worthy experiences. Some of them work as volunteers to do something for the country they are visiting. Many gap year volunteers are now spending a few months teaching English in Thailand, helping feed giant pandas in China or building a well(井) in a village in Africa.

    These young people's wish to explore the world is an expression of the values of the societies that they are part of. Both discovering the world and making a positive difference in it are important parts of the Western mind.

    Imagine a town with crosswalks but no pedestrians, cars and trucks but no drivers. Welcome to Mcity, a fake “city” built by researchers who are testing out the driverless cars of the future.

    The controlled test environment, which opened today (July 20, 2015) at the University of Michigan in Ann Arbor, covers 32 acres (the size of about 24 football fields) and contains all the trappings of a real suburb or small city. There is an entire network of roads lined with sidewalks, streetlights, stop signs and traffic signals. There's even a “downtown” area complete with fake buildings and outdoor dining areas.

    The idea behind Mcity is simple: test out new driverless car innovations in a human-free environment before these technologies are unleashed in the real world.

    "Mcity is a safe, controlled, and realistic environment where we are going to figure out how the incredible potential of connected and automated vehicles can be realized quickly, efficiently and safely," Peter Sweatman, director of the Mobility Transformation Center at U-M, said in a statement.

    The roads of Mcity are built to stand up to “rigorous, repeatable” testing, according to MTC officials. While Mcity drivers don't have to compete with real pedestrians, there will be one mechanical foot-traveler (a robot-like machine named Sebastian) that steps out into traffic to see whether the automated cars can hit the brakes in time. The fake city also features a traffic circle, a bridge, a tunnel, some unpaved roads, and even a four-lane highway with entrance and exit ramps, according to a report by Bloomberg Business.

    In addition to evaluating fully automated, or driverless cars, the researchers also hope to test out so-called connected vehicles within Mcity's limits. Connected cars can either communicate with one another (vehicle-to-vehicle control, or V2V) or with pieces of equipment, such as traffic lights, that are located near roadways (vehicle-to-infrastructure control, or V2I).

    Even the smallest details of Mcity have been planned out in advance to copy the conditions that connected and automated vehicles could face in the real world. For example, there are street signs covered up with graffiti, and faded yellow and white lane markings line the streets.

    Mcity is just one part of a much larger project that MTC and its partner organizations are establishing in an effort to get a whole fleet of connected and driverless cars on the road in Ann Arbor by 2021. In addition to the fake city, MTC is also continuing to launch connected and semi-autonomous(半自动) cars on real roadways. Eventually, the University of Michigan and the Michigan Department of Transportation said they hope to put 20,000 connected cars on the roads of southern Michigan.

    Over the years Lisa urged her sister Helen to prepare for her old age. Now they passed sixty. Lisa had a big house, Helen had the clothes on her back.

    Lisa had hated being a child and couldn't wait to grow up and buy herself everything. What Helen wanted was to go outside and play.

    When anyone would hire her, Lisa put herself to work. She never touched a penny of her money though her young mouth watered for ice cream and candy. When the dimes (一角硬币) added up to dollars， she lost her taste for sweets. And her bankbook became her most precious possession.

    Helen had a boyfriend Harry whose only ambition was to play a horn. That Helen married Harry straight out of high school was not surprising. Two or three times Lisa was halfway persuaded, but to give up a job that paid well for a homemaking job that paid nothing was a risk she was unable to take.

    Helen's married life was nothing for Lisa to envy. She and Harry played in second-rate bands. But Lisa had a big house because her boss offered her his first house at a price so low that it would be like losing money to refuse.

    Harry died abroad, in a third-rate hotel, with Helen crying as hard as if he had left her a fortune. He had left her nothing but his horn. Lisa knew she would have to bring her home.

    At dinner, Helen began to tell stories. They were rich with places and people, most of them lowly, all of them magnificent. Her face showed the joys and sorrows.

    Then Lisa knew why Helen didn't mention the shining room. Tonight Helen saw only what she had come seeking, a place in her sister's home and heart.

    She said, “That's enough about me. How have the years used you?” “I didn't use them,” said Lisa regretfully. “I saved for them but forgot to enjoy them. Now it's too near the end to try. ”Helen said, “Don't count the years that are left to us. At our time of life it's the days that count. You've too much catching up to do to waste a minute of a waking hour feeling sorry for yourself.” Lisa smiled.

    Little Women is the best-known work of author Louisa May Alcott. Published after the end of the Civil War, the book is about the lives of the author and her sisters. Although it was her most successful work, it was not her first.

    Alcott began writing at the age of 20, when she published her poem “Sunlight”. Throughout her early career, she wrote many poems and short stories for magazines. At the age of 22, she began to write fairy tales, romantic thrillers, and other novels, mostly to earn money. At a time when few opportunities were open to women, Alcott supported women's right to work. With her small income, she had long provided for her family.

    When the Civil War broke out, Alcott, at the age of 30, joined the war effort to fight against slavery. She had originally wished to serve as a soldier. However, women were not allowed in battle at that time. As a result, she became a Civil War nurse. Alcott's work as a nurse served as a milestone (里程碑) in her writing career.

    In December of 1862, she left New England to work in the Union Hotel Hospital in Washington, DC. There were few supplies, and doctors performed operations without painkillers. The conditions for patients and doctors were terrible. Within a few weeks, Alcott herself became so ill that she nearly died. She returned home and recovered slowly over a period of months.

    As soon as her health improved, Alcott started a new project. The letters she had sent home became the basis of a newspaper series about her experience as a Civil War nurse. She wrote about her tasks, the wounded soldiers she looked after, and the difficulties they faced. The series, Hospital Sketches, was a success, which received praise from readers and critics (批评) at the same time. Although her best-known work was yet to come, the success of Hospital Sketches marked the achievement of her dream to become a popular author.
