Part C Directions: Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written clearly on ANSWER SHEET 2. (10 points) Through necessity, Japan has adopted the bicycle as an essential component of transportation. The island nation’s limited geography, high density and lack of petroleum makes it an ideal location for small, efficient bicycles. 46) The destruction of Japan’s infrastructure during the second world war forced citizens to employ non-motorized means of transportation until the nation’s high speed railways were developed in the 1950s. With renewed infrastructure in place, the Japanese were quick to reject bicycling and its post-war reconstruction connotations and took to riding collector buses to and from railway stations. The bus system began to be overburdened in the late 1960s and riders began to find the system slow, expensive and inconvenient. 47) The disincentives of bus travel and surging environmental concerns associated with motorized travel initiated a shift in public opinion in favor of bicycling and bike ownership began to grow at 10% annually. Bicycles inundated railway stations and caused a bike pollution problem, inciting the Ministry of Transportation and Ministry of Construction to take action and build 22, 000 bicycle parking spaces in 1973. Japanese bike ownership doubled between 1975 and 1977, demanding additional construction projects in 1978. The Japanese government recognized that bike travel was favorable to other modes of transport for many reasons. Biking requires no petroleum and cyclists consume only 32 calories per mile compared to automobiles’ 1, 800 cal/m demand. Cyclists’ respiration contribute a scant 2 grams of carbon dioxide per passenger mile, while single-occupancy automobile emits 85 Co2 grams per mile. 48) On the road, eight cyclists can occupy the space needed for one automobile and when stopped, twenty bikes can be parked where there is space for just one automobile. These advantages prompted the government to consider other ways to promote bike travel including considerable urban design changes and the addition of 37, 000 miles of bike/pedestrian pathways during the 1970s. From an energy, pollution and density standpoint, the bicycle is more efficient that any other mode of short-trip travel. 49) Because commuters are reluctant to pedal more than about four miles, railway stations are located near residential areas to that commuters will be willing to pedal to the nearest train stop; innovations in high-density bicycle parking offers travelers in the busiest stations safe, fully automated mechanical storage facilities. Construction of the most expensive facilities cost $ 2, 000 per bike, compared to $ 4, 000 to $ 18, 000 for a single automobile parking space in the United States. 50) Japanese investments in bicycle infrastructure are offset by savings in subsidized bus systems as bicycle growth has surpassed bus rider ship growth; at some railway stations, more than 50% of commuters arrive by bike. On the road, eight cyclists can occupy the space needed for one automobile and when stopped, twenty bikes can be parked where there is space for just one automobile
In fact, there was hardly any activity or social event that could not be set to Music. Weddings, births, christening, funerals, picnics, parades-- 21 had their musical accompaniment.After the American Civil War (1860-1865), the Negroes had gained their freedom and were ready 22 a new type of music, 23 that would preserve their musical traditions but be fast and happy 24 their 25 freedom. They wanted something they could play as professional musicians for both black and white audiences. Jazz was the answer. It combined themes from Negro work songs, spirituals and blues, set to a fast beat, 26 the musicians improvising (即兴而作) as they went along, like the funeral marching bands. To be good, a musician had not only to remember his part but also 27 able to invent new variations on the spur (激励) of the moment.Jazz 28 the people, but popular 29 is changed many times in form, style, and tempo. Each change added something 30 . 21()
The poor are very wonderful people. One evening we went out and we picked up four people from the street. And one of them was in a most terrible condition - and I told the sisters: You take care of the other three. I take care of this one who looked worse. So I did for her all that my love can do. I put her in bed, and there was such a beautiful smile on her face. She took hold of my hand as she said just the words "Thank you" and she died.I could not help but examine my conscience before her and I asked what I would say if I was in her place. And my answer was very simple. I would have tried to draw a little attention to myself. I would have said I am hungry, that I am dying, I am cold, I am in pain, or something, but she gave me much more - she gave me her grateful love. And she died with a smile on her face. So did that man whom we picked up from the drain, half eaten with worms, and we brought him to the home. "I have lived like an animal in the street, but I am going to die like an angel, loved and cared for", he said at the end. And it was so wonderful to see the greatness of that man who could speak like that, who could die like that without blaming anybody, without cursing anybody, without comparing anything. Like an angel - this is the greatness of our people. And that is why we believe what Jesus has said: I was hungry, I was naked, I was homeless, I was unwanted, unloved, uncared for, and you did it to me.And with this prize that I received as a Prize of Peace, I am going to try to make the home for many people who have no home. Because I believe that love begins at home and if we can create a home for the poor I think that more and more love will spread. And we will be able through this understanding love to bring peace, be the good news to the poor, the poor in our own family first, in our country and in the world. When I pick up a person from the street, hungry, I give him a plate of rice, a piece of bread, I have satisfied. I have removed that hunger. But to a person who is shut out, who feels unwanted, unloved, terrified, the person who has been thrown out from society, that poverty is so full of hurt and so unbearable... And so let us always meet each other with a smile, for the smile is the beginning of love, and once we begin to love each other naturally we want to do something. ()is NOT inferred from the passage
