一家人坐电梯下来,电梯就是你的私人空间,一到大厅,有了外人,马上就进入了公共空间,应该小声说话。

为什么?怕干扰到别人。

这是对他人基本的尊重。

,即便在文明程度很高的今天,我们还是到处可见抽烟、吐痰,在公共场合大声讲话,大声打手机……餐馆里的众声喧哗就更不用说了。

对于这种现象,我们总是将其归因于未能把公共空间与私人空间区分开来。

②这诚然是没错的,但还只是问题的一个方面,也不是我要强调的重点。

③所谓“公共空间”应有两层意思,一是指日常公共生活的“公领域”,在这一领域中“私”是无所作为的,只要遵规矩、按常理、循旧俗就行;还有一层更重要的意思,就是一个将各种各样的私人意见、看法、观点等汇集为公意的地方。

没有这样一个“公共空间”,就不会形成真正的“公共意见”。

当然,在这一“公共空间”中,需要的是理性,要让人说话,同时要辩论。

④中国人的古训是在公共场所“莫谈国事”,而康德却说只有在公共场所,你才应该把自己的真实想法和盘托出,在私下里,你倒真应该执行你作为一个合法公民应尽的义务,要你怎么做你就怎么做,但所有的不满与意见都应该在“公共空间”得到发泄与表达。

青浦区2014学年第一学期期末考试试卷高三英语I. Listening Comprehension(略)II. Grammar and VocabularySection ADirections: After reading the passages below, fill in the blanks to make the passages coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.(A)During the summer days my mother built her fire in the shadow of our cabin. In the early morning our simple breakfast (25) (spread) upon the grass. The morning meal was our quiet hour. At noon, several (26) chanced to be passing by stopped to rest, and to share our luncheon with us. I loved (27) (well) the evening meal, for that was the time old stories were told.I was always glad when the sun hung low in the west, for then my mother sent me to invite the neighboring old people to eat supper with us. "Yes, yes, gladly, gladly I shall come!" each replied. My mission done, I ran back, (28) (skip) and jumping with delight.At the arrival of our guests I sat close to my mother, and did not leave her side. I ate my supper in quiet, listening patiently to the talk of the old people, wishing all the time that they would begin the stories. At last, when I (29) not wait any longer, I whispered in my mother's ear, "(30)them to tell an Iktomi story, mother."Then my mother said aloud, "My little daughter is anxious to hear your stories." As each in turn began to tell a legend, I pillowed my head in my mother's lap; and lying flat upon my back, I watched (31) stars one by one. The increasing interest of the tale aroused me, and I sat up eagerly listening for every word. The old women made funny remarks, and laughed so heartily (32) I could not help joining them.(B)The 43rd U.S. president George W. Bush stepped back into the spotlight when a library and museum dedicated to him opened to the public on May 1. the George W. Bush Presidential Library and Museum is dedicated (33) the campus of Southern Methodist University in Dallas, Texas. The library and museum is plentiful with exhibits on the historical events. “About 3000,000 visitors (34) (expect)”,said the library and museum spokesman.Presidential libraries are not libraries in the traditional sense. People cannot go to the George W. Bush Presidential library (35) (check) out a book. They are facilities that preserve documents and items of a president and his act of governing. (36) is preserved at a presidential library is available to the public to see and study because presidential libraries are public property (37) (belong) to the American people.1 / 10The Presidential library system began in 1939 when President Franklin Roosevelt ,during(38) second term in office, donated his personal and presidential papers to the government. Up until that point, presidential papers were destroyed, sold for profit, ruined by poor storage conditions, (39) were simply lost to the history.Roosevelt believed that presidential documents were an important part of the nation‟s heritage. He also donated a potion of his estate in Hyde PARK, New York, (40) his library and museum would be built. This began a tradition that would carry on with every president that followed.Section BDirections: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.A. numberB. recallC. constantD. additionE. achieveF. differentG. exposedH. obviouslyI. preciousJ. varietyK. typicallyIt's the customary bedtime practice every parent would feel fearful----being asked to read the same book for many times. But while the 41 repetition might be boring for mum or dad, it is the best way for toddlers to learn new words, according to research.The findings suggest parents are wasting money by spending a fortune on huge book collections in the hope they will inspire their little ones. Instead, a small selection of favourites such as The Very Hungry Caterpillar or The Gruffalo will 42 far more.Dr Jessica Hors t, of the University of Sussex‟s WORD Lab devised an experiment to check how quickly three-year-olds could recognize and 43 six new words. The children were visited three times in a week. One group heard the same story three times back-to-back each time and another was read three 44 stories. All had the same amount of new words which appeared the same 45 of times.When researchers returned a week later, they found the children who heard the same story over and over had 46 learned 3.6 of the new words. While those 47 to a variety of stories remembered only 2.6.They also noted the …repetition‟ group learned at a faster rate than those in the …48 ‟ group.Dr Horst said: …We are showing that less is more, to a point. An d, 49 , the more times you read to a child and the more books you have will help them. But you don‟t need to go crazy and buy every single Thomas the Tank Engine book. Reading the same books over and over again helps.‟Speaking of the 50 stud ies, we have found one in three don‟t read to their children before putting them to bed. Yet 30 minutes of one-on-one literacy sessions can improve reading age by nearly two years in less than five months.III. Reading ComprehensionSection ADirections: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.2 / 10Seven-year-old Jordan Lisle, in Mill Valley, California,joined his family at a packed after-hours school event last month aimed at inspiring anew interest: computer programming.The event was part of a national educational ___51____ in computer coding instruction that is growing at Internet speeds. Since December, 20,000 teachers from kindergarten through 12thgrade have___52_____ coding lessons, according to , a group backed by the techindustry that offers free curriculums. ___53_____, some 30 school districts have agreed to addcoding classes in the fall. And policy makers innine states have begun awarding the same ___54____ f or computer science classes that they do forbasic math and science courses, rather than treating them as optional courses.It is a remarkable change for computer science. Smartphones and apps are commonplace now, and engineering careers are __55____. To many parents, coding looks more like a basiclife skill, one that might someday __56____ a great job or even instant riches.The spread of coding instruction, ___57____ just new, is “never known—there‟s neverbeen a move this fast in education,” said Elliot Soloway, a professor of education and computerscience at the University of Michigan. He sees it as very positive, ___58____ inspiring studentsto develop a new passion, perhaps the way that teaching frog dissection (解剖) may inspire future surgeons and biologists.But the exposure to early coding comes with __59__, too. It is not clear that teaching basiccom puter science in grade school will beget future jobs or encourage __60___ creativity andlogical thinking. And particularly foryounger children, Dr. Soloway said, the activity is more like a video game, but not likely to impart actu al programming skills. A coding curriculum, ___61___ by Code. Org., combines basic instruction with videogames involving Angry Birds and hungry zombies.The lessons do not __62____ traditional comp uter language. Rather, they use simple wordcommands — like “move forward” or “turn right”— that children can click on and move around, to ___63____ an Angry Bird to capture a pig.The movement comes with no shortage of “we‟re changing the world” marketing passion from Silicon Valley.“This is strategically ___64____for the economy of the United States,” said JohnPearce, a technology businessman who has started a nonprofit, MV Gate, with Jeff Leane,to bring youth and family coding courses developed by to MillValley.Parents love the idea of giving children something to do with computers that they see as____65___, Mr. Pearce said.“I can‟t take my kid playing one more hour of video games,but if the children are exploring coding, I tell him I can live with that all night long.”51.

For each of them there are four choices marked A, B, C and D. Choose the onethat fits best according to the information given in the passage you have just read.(A)POETRY BY HEART By Andrew Motion (Viking £16.99)For three years, a terrific national competition has encouraged pupils aged 14 to 18 to learnand recite poetry — and this fat collection is the pool of 200 poems from which they have tomake their choice.This anthology makes a fine present for anyone interested in poetry, ranging from the earliestEnglish poem through every century to current poetry with many themes and from differentethnic backgrounds. Some of the choices seem odd to me —but that‟s part of the fun, as youwonder why. The notes make the book really useful. Every home should have a copy.POEMS THAT MAKE GROWN MEN CRYEdited by Anthony and Ben Holden (Simon & Schuster £16.99)This is a fascinating, wide-ranging selection of poems chosen by 100 well-known men —simply because they f ind them deeply moving. But grown men aren‟t supposed to cry, arethey?Some of the poems are about loss, as you‟d expect, but others are about deeply held politicalpassions or intense observations of nature. Each is introduced by the chooser, usually withfrank personal detail.4 / 10BLACK COUNTRY by Liz Berry (Chatto £10)This is a writer I‟m thrilled to disco ver — someone who takes a pride in the Midlands, whereshe lives. Berry uses some of the dialect words she heard as a child, turning ordinariness intosomething direct, tender and beautiful.The disagreeable Brummie accent becomes music in the hands of this fine young poet.LEARNING TO MAKE AN OUD IN NAZARETH by Ruth Padel (Chatto £10)Padel is one of our most talented writers. Poet, naturalist, musician and travel writer, sheturns her multi-layered poetic attention to the Middle East, seeking peace and harmonythrough sensitive and moving poems that offer hope even as they reflect upon struggle.Her proli fic and passionate creativity is proof that …making is our defence against the dark‟.66. Of the four books mentioned above, who are the creators of the poems?A. Andrew Motion and Liz BerryB. Liz Berry and Ruth PadelC. Anthony and Ben HoldenD. Ruth Padel and Ben Holden67. Which of the following statements is true?A. Students aged 14 to 18 can choose a poem from Black Country to take part in a competition.B. Liz Berry can change the unpleasant Brummie accent into a beautiful song.C. Men will cry after they read the poems written by 100 distinguished persons.D. You will read personal perspectives in Poems That Make Grown Men Cry.68. My cousin is obsessed with poetry of different kinds, so my first choice as a gift for him would be______.A. Learning to Make an Oud in NazarethB. Black CountryC. Poetry by HeartD. Poems that Make Grown Men Cry69. Which of the four books may probably give the people living in psychological suffering comfortand relief?A. Poems that Make Grown Men CryB. Poetry by HeartC. Black CountryD. Learning to Make an Oud in Nazareth(B)Emergency rooms (ER) are supposed to cure people but Dr. John Stemgold wonders if working inan ER in Willits made him sick. The ER was downwind of the Remco chrome plant. “I used to sit facing that window and kind of daydream out the window, looking at Remco, looking at the fog coming out of there. Then I would cough and cough.” Stemgold said.What Dr.Stemgold didn‟t know was that Remco was flowing out Chromium VI into the air--- a chemical known to cause cancer and breathing problems in humans. A recent state health department study found that people who were in Willits when Remco was in operation from 1964 to 1995 are at higher risk for cancer because of Chromium VI exposure.Today Dr.Stemgold has lots of time to play his guitar. It turns out he has a form of breathing5 / 10difficulty. Hospital chemicals cause coughing so violently that he‟s broken bones and it‟s cost him his career. Others in this town believe the Chromium has made them sick, too, and their families. Actually, Chromium VI was classified as a carcinogen , a cancer-causing substance, thirty years ago, Twenty years ago, a group of state scientific specialists found no exposure level below which carcinogen effects would not have some probability of occurring. Still, Remco was allowed to flow out Chromium VI into the air.In the battle to balance public health and a healthy economy, laws often favor business, Alan Ramo is a professor of law at Golden Gate University. “There is a real drive to make money, to have employment. When there‟s a real job that‟s available and a theoretical risk of a chemical, jobs win out, business wins out.”And chemicals are allowed to flood the marketplace and the government requires strict testing before any drugs can be sold. But the vast majority of industrial chemicals are put into use little testing of any kind Chemicals that people like us, you and me might be exposed to. Marilyn Underwood is with California state health department. “ You need to have the convincing evidence that something is bad to then start regulating it.” However, in most cases, chemicals are not te sted until someone reports the abnormal, unnatural condition of the environment in general.“I think that if people really knew what really goes on with environmental protection I think they would be shocked and they should be.” Says Professor Ramo. “It might be valuable for other people to know what has happened to me, not for me but for them.” He said “because they might be in a similar situation because of where they work.”70.

The Mountain View California-based firm says that a high percentage of people suffer from neck pain and associated problems, probably caused by more individuals doing office jobs, which generally involve leaning over computer keyboard.The device contains sensors, several different types of instruments to monitor movement, plus a monitor to shake.

It also offers additional features such as shaking to indicate alerts on a user‟s smartphone, but it is not currently clear whether it can also be used like bands, to count steps, and so on.The Fineck has a battery life of around seven days and takes one hour to charge.

Then answer the questions or complete the statements in the fewest possible words.The one place you really don‟t want to be on weekend is in hospital. Last week, it wa s revealed in the research by Guy‟s and St Thomas‟ hospital in London, that stroke patients admitted on a Saturday or Sunday are up to 16 percent more likely to die .Meanwhile , a report earlier this year from NHS England found that all patients are 12 percent more likely to die if admitted to hospital at the weekend ------this was because fewer senior staff were available and there was a lack of access to key physical examination tests, such as scans.But even if you‟re not in hospital, weekends can be a health danger. You might have thought it was your chance to recover after a hard week ,but as we reveal, while they won‟t kill you, weekends may be bad for your health.Headaches can occur more often at the weekend--------especially on a Saturday-------because of a chance in our routine, suggests Dr Andy Dowson, director of headache services at King‟s College Hospital, London. He says:” if you are used to eating at a certain time of day or getting up and falling asleep at the same time, not continuing in the normal way at the weekend can cause headaches as your body and brain try to adjust to irregular meals or having a lie-in.” one theory is that the hypothalamus is very sensitive to any change in the body‟s routine.Caffeine withdrawal may be another factor, if you usually drink three or four cups of tea or coffee on week days to help you concentrate at work, but don‟t at the weekend, your body can go into withdrawal . it‟s thought caffeine also influences the chemical messenger that widens bloo d vessels in the brain----without it, these vessels narrow again, triggering a headache.Lying on the sofa in front of TV for hours watching your favorites after a week of running around can make heartburn worse----or even cause it to happen, as sitting with the head and shoulders bent forward puts pressure on the stomach, forcing acid up the gullet, the tube through which food passes from the mouth to the stomach, say Steven Mann, a gastroenterologist at the Royal Free London Trust.Acid reflux can also become a problem at the weekend you cannot bear because of less regular meal times as a result of late nights and lie-ins, explains Dr Mann. And having a take away could be the final straw. “ Oily, fatty food stimulates acid production, which can also cause problems such as heartburn and overflowing with the food.”Dr Mann adds.(note: Answer the question or complete the statements in NOT MORE THAN TWELVE WORDS) 78. besides fewer staff available, why are weekend patients admitted to hospitals more likely to die?79. what are the two factors which may cause headaches?80.
