Nowadays airfare isn't getting any cheaper with fuel costs rising every day. Luckily, there are plenty of ways to find the most affordable fares and also avoid paying as many extra charges as possible when you plan ahead.

    You may not  have heard of Ashoka,  but for the past 27 years,this association, founded by Bill Drayton, has fought  poverty (贫穷)and sickness, promoted education and  encouraged small businesses. To support these worthy causes, Ashoka provides money for the world's most  promising "changemakers" seeking to solve (解决) urgent problems and would like to create a  world in which every citizen is a changemaker.

    Drayton believes that anyone can become an agent for change. The important thing is to simply give yourself permission. If you see a problem that you care about, you can help solve it. The young in particular are willing to accept this concept because at heart every child wants to grow into a happy, healthy,  contributing adult. In fact It is many young people's ambition to set up programmes or businesses that improve social conditions. An excellent example is an Ashoka project started in 1995 in Dhaka, which handled the rubbish problem facing the city ,helped local farmers and provided an income for poor people there .

When Masqsood and Iftekhar began to study the problem of all the uncollected rubbish that lay in Dhaka's streets, Attracting tats and disease , they discovered that 80% of it was natural waste . So they educated the poor people in the city to compost (把……制成堆粪)this waste . They knew that they would have a market for the end product because local farmers were struggling with chemical ferntilisers (化肥) which were expensive and had reduced the natural minerals in the soil over the years . At first , they were refused ,but once they were able to persuade them that there was money to be made , the project took off. In 2009 sales were $14,000.

    Drayton is optimistic that in ten years Ashoka will be making really serious ,practical progress in bringing about social change by changing the way we look at economic development.

    The British are known for their sense of humor. However, it is often difficult for foreigners to understand their jokes. The main point to remember is that the British often use understatement.

    Understatement means saying less than you think or feel. For example, if someone gets very wet in a shower of rain, he might say, "It's a little damp (潮湿的) outside." Or, if someone is very impolite and shouts at another person, someone else might say, "She isn't exactly friendly." Understatement is often used in unpleasant situation or to make another person look silly. Understatement plays an important part in British humor.

    Another key to understanding British humor is that the British like to make fun of themselves as well as others. They often laugh about the silly and unpleasant things that happen to our everyday life when someone accidentally falls over in the street. They also like to make jokes about people from different classes of society. They like to make jokes about their accents, the way they dress and the way they behave. What's more, the British love to watch comedies (喜剧) about people who do not know how to behave in society. The comedies series Mr. Bean is a good example of this kind of humor.

    Mr. Bean is the character created by British actor Rowan Atkinson in 1990. Mr. Bean doesn't talk often, and instead he uses his body movement and facial expressions to make people laugh. Perhaps what makes Mr. Bean so funny is that he does things that adults in the real world cannot do. Mr. Bean is popular in many countries around the world because you do not have to speak English to understand the humor. Because of this, many people have become familiar with the British sense of humor.

    I was deeply moved by the kindness of an elderly flower seller at Sydney's Central Station one evening.

    I was feeling as cold as the winter winds quickening the steps of the people who buried chins (下巴) in scarves and hands deep into coat pockets. In many ways, 2018 had proven an arduous year. My teenage daughter had left home for university, my job of 23 years was no more, and a creative project I'd given my all to for years had also been suddenly called off. I also found out a person I considered a friend was far from it.

    A year earlier, I'd dreamt about an earthquake. In the dream, a red light flashed inside a building and then the earth began to rock. Walls fell down on me as I ran into the open, feeling sorry for the people I hadn't loved enough. Before I was buried completely by the falling world, I shouted, "Abuelo, ayudame," in my native Spanish. "Grandfather, help me!"

    Now, with the very real aftershocks of a series of unexpected endings, I walked into a little flower shop to buy a gift for a friend. The gentleman at the shop looked at me and turned away for a moment, returning with a fragrant flower. "For you. You need to smile today," he said in a rich and beautiful accent, offering me the flower with eyes full of care. It took all my strength not to cry. Then he gave me a grandfatherly hug that made me want to tell him everything.

    Instead, I thanked him and headed for the train. How did he know? I wondered. For the first time in weeks, I felt hope.

    On May 29, 1973, Thomas Bradley, a black man, was elected mayor of Los Angeles. Los Angeles is the third largest city in the United States, with a population of three million. About sixteen percent of the city's population are black.

    News of this election appeared on the front pages of newspapers everywhere in the United States. Here is how one major newspaper reported the event.

    LOS ANGELES ELECTS BRADLEY MAYOR UNSEATING YORTY

    BLACK WINS 56% OF VOTES

    Bradley called his victory over Yorty "the fulfillment of a dream". During his childhood and youth, people had kept telling him, "You can't do this, you can't go there, because you are a Negro." Nevertheless he had won a decisive victory over a man who had been won 43.7 percent.

    Los Angeles voters have had many opportunities to judge. Thomas Bradley had to form an opinion of him. The son of a poor farmer Texas, he joined the Los Angeles police force in 1940. During his twenty-one years on the police force he earned a law degree by attending school at night. He was elected to the city council years ago.

    At the time of the Los Angeles election, three other American cities already had black mayors, but none of these cities had as large a population as Los Angeles. Besides, the percentage of blacks in those other cities was much larger. Cleveland, Ohio, had thirty-six percent black when Carl Stokes was elected mayor of Cleveland in 1967. In the same year Richard Hatcher was elected mayor of Cary. In Newark, New Jersey, sixty percent of the population were black when Kenneth Gibson was elected in 1970. Thus election of a black mayor in those cities was not very surprising.

    In Los Angeles, thousands of white citizens voted for Thomas Bradley because they believed he would be a better mayor than the white candidate. Bradley had spent forty-eight of his fifty-five years in Los Angeles. Four years ago, Bradley lost mayoral election to Yorty. This time Bradley won.
