Famous centenarians (百岁老人) still active in arts, science are in no mood to retire. "Those who stand still, die," is one of Oliveira's favorite phrases. He knows from experience what it means, as the Portuguese film director has reached the age of 102 and is still active in his profession. Every year, Oliveira shoots a film and is currently working on his next project. "You have to work, work, work in order to forget that death is not far away," he said. When asked about his age, Oliveira said with some humility: "It's down to mother nature. It gave to me what it took from others."
Being both mentally and physically fit in old age is partly a matter of luck, but it also has something to do with character. Not every white-haired person is wise and social skills, openness and the ability to train the brain are essential for senior citizens.
Along with the architect Oscar Niemeyer (103), Nobel laureate Montalcini (101) and director Kurt Maetzig (100), Oliveira is one of those people of whom it would be very wrong to think as members of a listless elderly generation.
Another master in his profession is the architect Oscar Niemeyer. The 103-year-old Brazilian is best known for his futuristic-looking（未来派的）buildings in Brasilia, but he also speaks out on behalf of the poor. "The role of the architect is to struggle for a better world where we can develop a form of architecture that serves everyone and not just a privileged few," said Niemeyer recently. He spends almost every day working in his office in Copacabana, and even when he falls ill he keeps working on ideas: After a gallbladder (胆囊) operation he composed a samba tune (桑巴舞曲) in the clinic.
Another man who could sing a song about age is 107-year-old Heesters. The Dutch-born opera singer spent most of his life performing in Germany, where he still works. Recently Heesters said: "I want to be at least 108-years-old." He also plans to keep performing. "Should I just sit at home and wait until they come and pick me up?" Heesters has not given up trying to add to his tally of awards and is looking for a "good stage role".
Italian scientist Rita Levi-Montalcini, who is 101-year-old and is still active in medical science, has described the force that keeps driving her on: "Progress is created through imperfection." In 1986 she and her lab colleague were awarded the Nobel Prize for Medicine for their work on nerve growth factor. She's convinced that humans grow on challenges.
With so many brilliant examples given, we can see clearly that age is no barrier to some high achievers.

From earliest times, the English, for instance, have believed in certain symbols and customs which could bring good fortune as well as ward off evil spirits. Old customs seldom die, so don’t be surprised because some of these customs are still practiced daily in today’s society. Below are symbols of luck from a popular culture magazine.
Old Boot
In ancient days, old boots or shoes were said to hold the good spirit and courage of their owners. Therefore, it was a common belief that an old boot was a good luck charm. For instance,
if a fisherman caught himself an old boot instead of fish, it is believed that at the end of the day he
would be able to catch and take home a huge amount of fish. In north England, the wives of sailors would usually throw old boots or shoes at the departing(离开) ships to ensure their
husbands' safe journey. Old boots were also left on the roofs of old houses to drive off evil spirits.
◆Wood
Back in pagan (异教徒) times, touching the tree was a sign of respect to the gods after a favor has been requested, or thanks to the gods for a request that had been fulfilled. Later, the
British still held their belief that wood is holy as Christ died on a wooden cross. Even now, people
still have the habit of trying to touch or knock on wood after talking bad things about other people, and so on, so that the action will get rid of any bad luck during the day.
◆Horseshoe
The horseshoe is considered a lucky symbol in English customs. It is similar to the other
symbols associated with good fortune in other cultures such as “U”. “U” shape is often said to be the symbol of fertility and also possesses power to drive away evil spirit. As it is made of iron and used for horses, horseshoes are also linked to strength and power. As a result, combining all these signs of good luck, the horseshoe is regarded as a powerful device to bring fortune and keep evil spirits away. It is usually nailed to the front door to protect the household from uninvited visitors like witches and evils. However, the horseshoe must be placed in a standing “U” position so that
the good fortune will be held by the household.
◆Rabbit’s Foot
In the old English custom, the hare (not rabbit) was said to have an evil eye, whose glance
can only be countered by people who own a hare’s foot. In the old days, it was said that the warrior Queen Boadicea of Norfolk, East Britain, brought a hare with her to ensure luck in battle
against the Romans who had invaded her kingdom. This brought people to believe that the hare had magical powers. However, the pagan practice of worshiping the hare eventually stopped after
most British began to believe in Christianity in the 6th century. Nevertheless, many British carried hare’s feet in their pocket or purse. Later, rabbits were introduced in Britain from the other
European countries, and since rabbits can be caught more easily than har es, the rabbit’s foot
replaced the hare’s foot as a lucky charm.
◆Coin
Coins, especially gold coins, were said to bring good fortune to the person who possessed them. Gold, like in any other culture, was always a symbol of wealth. In the past, "lucky" gold
coins were turned into rings to be worn as a cure for many types of illness. Sometimes, brides put them in a shoe to ensure a good married life. The English also dropped coins into wells to make a
wish in the hope that their dreams would come true. This is due to the fact that people at that time believed there were good spirits who lived in the wells, fountains or springs.
46. Which symbol of luck is seen as a sign of strength and power?
A. Horseshoe
B. Old boot
C. Wood
D. Rabbit’s foot
47. To get rid of bad luck after speaking ill of other people, the English are likely to
___________.
A. drop gold coins into wells
B. carry hare’s feet in their pocket
C. touch or knock on wood
D. throw old boots at the sailing ship
48. Which of the following statements is TRUE according to the passage?
A. Coins and old boots could be thrown to ensure a happy married life.
B. Rabbit’s foot as well as wood is related to some religious belief.
C. Both wood and coins could be touched to show thanks to the gods.
D. Old boots and horseshoes should be put on the roof to drive away evils.
49. What is the passage mainly about?
A. The origin of five symbols of luck around the world.
B. Some lost customs about good fortune in the English culture.
C. The differences of five symbols of luck in the English culture.
D. An introduction to some symbols of luck in the English culture.

A woman named Emily renewing her driver's license at the County Clerk's office was asked by the woman recorder to state her occupation. She hesitated, uncertain how to classify herself.
"What I mean is," explained the recorder, "do you have a job, or are you just a… "
"Of course I have a job," responded Emily. "I'm a mother."
"We don't list mother as an occupation ... Housewife covers it," said the recorder emphatically.
I forgot all about her story until one day I found myself in the same situation, this time at our own Town Hall. The Clerk was obviously a career woman, confident, efficient, and possessed of a high sounding title . “Wha t is your occupation?" she asked.
What made me say it. I do not know ... The words simply popped out. "I'm a Research Associate in the field of Child Development and Human Relations."
The clerk paused, ballpoint pen frozen in midair, and looked up as though she had not heard right.
I repeated the title slowly, emphasizing the most significant words. Then I stared with wonder as my statement was written in bold, black ink on the official questionnaire.
"Might I ask," said the clerk with new interest, "just what you do in your field? "
Coolly, without any trace of panic in my voice, I heard myself reply, "I have a continuing program of research (what mother doesn't), in the laboratory and in the field (normally I would have said indoors and out). I'm working for my Masters (the whole damned family), and already have four credits (all daughters). Of course, the job is one of the most demanding in the humanities (any mother care to disagree?) and I often work 14 hours a day (24 is more like it). But the job is more challenging than most careers and the rewards are more of a satisfaction rather than just money."
There was an increasing note of respect in the clerk's voice as she completed the form, stood up, and personally showed me to the door.
As I drove into our driveway, buoyed up (依托) by my glamorous new career, I was greeted by my lab assistants--aged 13, 7, and 3. Upstairs I could hear our new experimental model, (a 6- month- old baby), in the child-development program, testing out a new vocal pattern.
I felt proud! I had scored a beat on bureaucracy(官僚主义)! And I had gone on the official records as someone more distinguished and irreplaceable to mankind than "just another mother".
Motherhood ... What a glorious career! Especially when there's a title on the door.
50. What can we infer from the conversation between the woman and the recorder at the
beginning of the passage?
A. The recorder was impatient and rude.
B. The woman felt ashamed to admit what her job was.
C. The author was upset about the situation that mothers faced.
D. Motherhood was not recognized and respected as a job by society.
51. How did the female clerk feel at first when the author told her occupation?
A. curious
B. indifferent
C. puzzled
D. interested
52. Why did the woman clerk show more respect for the author afterwards?
A. Because the author cared little about rewards.
B. Because she admired the author’s research work in the lab.
C. Because she thought the author did admirable work.
D. Because the writer did something she had little knowledge of.
53. What did the author think of the job as a mother of four?
A. demanding and rewarding
B. satisfying and interesting
C. tiring and annoying
D. disgusting and challenging
54. What is the author’s purpose of writing the passage?
A. To show that how you describe your job affects your feelings toward it.
B. To argue that motherhood is a worthy career and deserves respect.
C. To show that the author had a grander job than Emily.
D. To show that being a mother is hard and boring work.
D
Tom appeared on the sidewalk with a bucket of whitewash and a long-handled brush. He stopped by the fence in front of the house where he lived with his aunt Polly. He looked at it, and all joy left him. The fence was long and high. He put the brush into the whitewash and moved it along the top of the fence. He repeated the operation. He felt he could not continue and sat down.
He knew that his friends would arrive soon with all kinds of interesting plans for the day.
They would walk past him and laugh. They would make jokes about his having to work on a beautiful summer Saturday. The thought burned him like fire.
He put his hand into his pockets and took out all that he owned. Perhaps he could find some way to pay someone to do the whitewashing for him. But there was nothing of value in his pockets—nothing that could buy even half an hour of freedom. So he put the bits of toys back into his pockets and gave up the idea.
At this dark and hopeless moment, a wonderful idea came to him. It filled his mind with a great, bright light. Calmly he picked up the brush and started again to whitewash.
While Tom was working, Ben Rogers appeared. Ben was eating an apple as he walked along the street. As he walked along it, he was making noises like the sound of a riverboat. First he shouted loudly, like a boat captain. Then he said “Ding－Dong－Dong”，“Ding－Dong－Dong” again and again, like the bell of a riverboat. And he made other strange noises. When he came close to Tom, he stopped.
Tom went on whitewashing. He did not look at Ben. Ben stared a moment and then said: “Hello! I'm going swimming, but you can't go, can you？”
No answer. Tom moved his brush carefully along the fence and looked at the result with the eye of an artist. Ben came nearer. Tom's mouth watered for the apple, but he kept on working.
Ben said, “Hello, old fellow, you've got to work, hey？”
Tom turned suddenly and said, “Why, it's you, Ben! I wasn't noticing.”
“Say—I'm going swimming. Don't you wish you could? But of course you'd rather work—wouldn't you? Of course you would.”
Tom looked at the boy a bit, and said, “What do you call work？”
“Why, isn't that work？”
Tom went back to his whitewashing, and answered carelessly.
“Well, maybe it is, and maybe it isn't. All I know is, it suits Tom Sawyer.”
“Oh come, now, you don't mean to say that you like it？”
The brush continued to move.
“Like it? Well, I don't see why I shouldn't like it. Does a boy get a chance to whitewash a fence every day？”
Ben stopped eating his apple. Tom moved his brush back and forth, stepped back to look at the result, added a touch here and there, and stepped back again. Ben watched every move and got more and more interested. Soon he said，“Say, Tom, let me whitewash a little.”
Tom thought for a moment, and was about to agree, but he changed his mind.
“No—no—it won't do, Ben. You see, Aunt Polly wants this fence to be perfect. It has got to be done very carefully. I don't think there is one boy in a thousand, maybe two thousand, that can do it well enough.”
“No—is that so? Oh come, now—let me just try. Only just a little.”
“Ben, I'd like to, but if it isn't done right, I'm afraid Aunt Polly … ”
“Oh, I'll be careful. Now let me try. Say—I'll giv e you the core of my apple.”
“Well, here—No, Ben, now don't. I'm afraid …”
“I'll give you all of it.”
Tom gave up the brush with unwillingness on his face, but joy in his heart. And while Ben worked at the fence in the hot sun, Tom sat under a tree, eating the apple, and planning how to get more help. There were enough boys. Each one came to laugh, but remained to whitewash. By the time Ben was tired, Tom sold the next chance to Billy for a kite; and when Billy was tired, Johnny bought it for a dead rat—and so on, hour after hour. And when the middle of the afternoon came, Tom had won many treasures.
And he had not worked. He had had a nice idle time all the time, with plenty of company, and the fence had been whitewashed three times. If he hadn't run out of whitewash, Tom would have owned everything belonging to his friends.
He had discovered a great law of human action, namely, that in order to make a man or a boy want a thing, it is only necessary to make the thing difficult to get.

B. 5.

My friendship with Yang Qing began when we meet in our school photo club. From then on we became good friend. We had common interest in basketball and often shared their experience about photographing. On weekends we rode to play the basketball together. Now in Senior 3, we seldom play together, or still keep in touch and encourage each other. With the entrance exam comes near, I’m worried about what my life will like as we may go to different universities. But now what doesn’t worry me any more because I know just as the old saying goes: Truly friendship will always live on no matter where far apart we are.

历史1101 杨佳赢1119700110 萧山历史变迁 我的家乡位于浙江省杭州市的萧山区，主要介绍一下萧山的历史地理变迁史。 近年来，在萧山城区西南的城厢街道湘湖村发现了跨湖桥新石器时代遗址，该遗址是浙江史前考古取得的一项重大成就。经过1990年、2001年和2002年三次考古发掘，发现了大量文物及动植物遗存，经碳十四测定距今8000—7000年的新石器时代早期，表明了萧山拥有8000年的文明史。萧山是古越文化的发祥地之一，境内保存有多处古越遗址，建县于公元2年的余暨县就是今日萧山的雏形。 拘距今12000—10000年前以木本花粉居首位，松、柏有一定数量，反映路缘山地为阔叶、针叶混交林，沿海平原分布着盐生草本植物，相当于目前暖温带南缘的植被，气温比现在低2—3度，气候冷凉略干；之后出现了少量常绿阔叶林，气温比现在低1—2度，比前期略温暖。现在的萧山地处亚热带季风气候区南缘，总得气候特征为：冬季长，春秋短，四季分明，光照充足，雨量充沛，温暖湿润。总之，目前已经发现的这些早期遗址的形成具有可信的环境背景。 三皇至夏朝初年，萧山地域为扬州属地；夏少康时，少康封其庶子于越，由此到战国初年，萧山地域为越过辖境。周显王三十六年（公元前333年），楚灭越，萧山地域属楚国。秦始皇二十六年（公元前221年），置会稽郡，萧山属会稽郡地；西汉元始二年（公元2年），始建县，名余暨，属会稽郡；三国东吴黄武年间（公元222--229年），改名永兴，属会稽郡。唐天宝元年（公元742年），以萧然山为名，改永兴县为萧山县，属越州。作为山名的萧山，早在《汉书·地理志》余暨县名之下已有记载，其来历是当年越王勾践被吴王夫差战败，率剩下兵卒停留于此，四顾萧然，故称此山为萧然山，亦名萧山。南宋建炎四年（1130年），高宗驻跸越州，以“绍奕世之宏休，兴百年之丕绪”之意，次年改为绍兴元年，升越州为绍兴府，萧山县隶属于绍兴府。元至元十三年（1276年），改绍兴府为绍兴路，萧山县属绍兴路。明洪武二年（1369），复为绍兴府，萧山县属绍兴府，清继明制。清咸丰十一年（1861年），太平军占领萧山期间，为避西王萧朝贵、南王冯云山之讳，改萧山为“莦珊”。清同治二年（1863年），复“莦珊”为萧山，属绍兴府。民国二年（1912年）废府，萧山县为省直属县。1949年5月5日，中国人民解放军解放萧山，为省直属县。 中华人民共和国成立后，萧山与绍兴、诸暨两县相邻的部分地域，在行政区划上有几次变动。1950年10月，绍兴县进化区所属青化、进化、城山等15个乡及临浦镇原属绍兴县部分划归萧山，萧山县钱清镇划归绍兴县，到后来的1956年也有一些变动。萧山还有一个重要事情就是围垦，在中华人民共和国建国后，经历年筑堤围圈，开发建设钱塘江畔的新土地。其北、东、西三面濒临钱塘江，南接南沙大堤，经过多次大小规模不同的围垦，至2000年底，萧山围垦面积达52.62万亩。1987年，国务院批准萧山设立县级萧山市，2001年撤销县级萧山市，成立杭州市萧山区。 萧山8000年文明，2000年建县史，以及改革开放30年，种种厚重的历史和伟大的成就激励着一代又一代的萧山弄潮儿奔竞不息，勇立潮头，敢为天下先。
2018年浙江省杭州高中高考英语最后一卷 副标题 一、阅读理解（本大题共10小题，共25.0分） A One day your pocket might power your smart phone．Soon you may never have to worry about your smart phone running out of juice．Your clothing will simply power it back up for you．That's the word from scientists at China's Chongqing and Jinan Universities in a study just published in the journal ACS Nano． Researchers have been hard at work during the last few years trying to create wearable energy，or clothes that can charge things．The assumption is simple．People today rely heavily upon devices such as smart phones and tablets．And they're looking for ways to recharge these devices on the go．So if you could design clothing fabric that could make use of solar power -one of the most widely available and inexhaustible renewable energy sources - you'd be able to charge your various devices with ease． Scientists have had some past success creating energy-harvesting fibers．But there was always one problem when they tried to fashion these threads into self-powered smart clothes：The fibers they designed got damaged during the clothing manufacturing process，namely during the weaving and cutting．The Chongqing and Jinan University scientists say they've solved this problem because the energy-collecting and energy-storing threads they created are highly flexible - each individual thread is easily bendable，and not simply the fabric as a whole．The team's sample textile can be fully charged to 1.2 volts in 17 seconds by exposure to sunlight - enough voltage that your future smart T or smart dress might be able to power small electronics．It's durable，too；their research showed there was no descent in the fabric after 60 days．But don't worry that this means the fabric is similar to rough cloth．The scientists note their textile can be fashioned into numerous different patterns，and tailored into any designed shape，without affecting performance． 1.What does the underlined phrase "running out of juice" in paragraph 1mean？______ A. Being lacking in energy． B. Wanting to have some juice． C. Being picked out of a drink． D. Having some water running out． 2.Why could smart dress charge a phone？______ A. A solar cell is attached to the dress． B. The fabric of the textile contains current． C. The fabric of the textile is easily bendable． D. The fabric of the textile could collect and store the solar energy． 3.What is the scientists' attitude towards the scientific technology？______ A. Optimistic． B. Pessimistic． C. Neutral． D. Doubtful． 【答案】 【小题1】A 【小题2】D 【小题3】A 第1页，共13页
