Why is it not possible for us to hold a really objective discourse(论述)on the subject? In part, because it is very difficult to separate the psychological from the symbolic, the symbolic aspects are definitely cultural. Often, and this without our realizing it, they influence our understanding of colors and the following emotions - both psychological aspects. Black and white are good examples. In western countries, black is considered serious, dramatic and sometimes sad. People are warned against its potentially depressing effects on decoration. Black is the traditional color of mourning. White, on the other hand, is associated with purity, peace and optimism. For those reasons, white is the traditional color of bridal dresses. No one would think of attending a funeral in white. Any more than it would occur to a bride to wear black. We simply remain convinced that it is not in the "nature" of those colors. Yet, in certain oriental countries, it is white, not black that is the color of mourning.
That h aving been said, there is some ―overlapping‖ in the properties different cultures attribute to certain colors. For example, Feng Shui, the traditional Chinese philosophy that distinguishes between good and evil influences explains colors much in the same way as the majority of western color specialists. Is that to say that colors have real natural properties which all humans perceive(感知) in the same way or is the phenomenon an example of the
cross-influences that affect the thinking of cultures brought closer to one another by a certain Venetian(威尼斯人) called Marco Polo? It is difficult to say.
But, be that as it may, colors do affect us. And if you feel emotions for a certain color, note them and remember them. You may even wish to consider them next time you are planning to decorate. The decision is yours!
56. Most of the time, we ignore ______ when choosing colors for decoration.
A. personal taste
B. our aesthetics
C. cultural effects
D. psychological effects
57. Why is it not possible for us to hold a really objective discourse on the subject?
A. Because it is often nothing more than a reflection of our cultural belongingness.
B. Because the colors have the properties for generations.
C. Because it is difficult to separate the psychological from the cultural.
D. Because the symbolic aspects influence our perception of colors.
58. The italicized word ―overlapping‖ is paragraph 6 is closest in meaning to______
A. difference
B. conflict
C. sameness
D. agreement
59. In western countries, white is ______.
A. preferred by bridals
B. used in a funerals sometimes
C. depressing in decoration
D. pure in its nature

60. According to the author, which of the following statements is certain?
A. Different cultures can have the same properties of colors.
B. If you feel emotions for a color, note them and remember them.
C. All humans perceive colors’ natural properties in the same way.
D. Marco Polo disclosed the psychological effects of colors.
B
All it took was a slice of Xinjiang cake to spark heated debates online over China's policy on ethnic（民族的）minorities .
Since Monday, qiegao (cut cake) has been a trending topic on Sina Weibo, China’s main Twitter-like microblogging service.
The cake was a reference to Xinjiang’s famed nut cake, sometimes k nown by its old Turkic name baklava, a popular pastry across Central Asia and the Middle East. In Xinjiang, they are sold by Uygur vendors（小贩）on tricycles who are known to charge dubious prices depending on the time and season.
The ethnic flare-up started after the Yueyang police from Hunan province posted a message on their official Weibo account. It reported a dispute in Pingjiang county over an overpriced piece of nut cake between a Xinjiang Uygur vendor and a villager named "Ling".
Villager Ling got into a fight with a Uygur due to a misunderstanding. The verbal dispute eventually escalated into a fight and then a mass fight. As a result, two people were injured and Xinjiang nut cakes worth about 160,000 yuan (US$25,000) were destroyed. The total damage was worth 200,000 yuan which included a broken motorcycle and injuries to people. Local police have detained（扣留）Ling. The 16 Uygur sellers were dully compensated and sent back to Xinjiang.
"Yueyang police incident" quickly became one of the most popular topics on Weibo. Yueyang police removed the post shortly after. As of Tuesday night, the topic was still amassing more than 66,000 hits.
The incident is just one of many similar cases of ethnic tensions across China, notably in Xinjiang province, where deeply entrenched social and racial frictions between the dominant ethnic Han Chinese and minority Uygur Muslims occasionally spark violence. Many Uygurs living in major Chinese cities are viewed by locals as thieves, crooks and even terrorists.
61. Which of the following is true?
A. The dispute is between a Xinjiang Uygur vendor and a policeman.
B. Nut cake is a popular pastry across East Asia and the Middle East.
C. The prices of Baklava will change according to the time and season.
D. The demand of the 16 Uygur sellers were refused and they were sent back to Xinjiang.
62.How much did the broken motorcycle cost？
A．160,000 yuan B.200,000 yuan C.40，000yuan D. We don’t know
63. What’s the best title of the passage?
A.World's most expensive baklava.
B.Ethnic tensions across China.
C. Pay attention to the Uygurs
D. Misunderstanding caused by a fight
64. What can we infer from the passage?
A. Yueyang police are afraid of the Xinjiang Uygur vendor
B. It’s not the only ethnic tension across China,
C. Many Uygurs living in major Chinese cities are viewed by locals as thieves, crooks and even
第6页共13页
terrorists.
D. Villager Ling got into a fight with a Uygur due to a misunderstanding.
65. Where is this passage probably from?
A. Microblogging.
B. Textbook.
C. Newspaper.
D. Article.

The quality of water supply in southern Beijing has been improving in recent years, an official said.
In addition to improvements in the network of pipes, the government has been upgrading three recycled water plants in the south of the capital, said Zhao Lei, spokesman for the Beijing Municipal Commission of Development and Reform.
"The transformation of the three plants has increased the recycled water processing capacity by 160,000 cubic meters per day," he said.
In addition, the city is also speeding up the construction of sewage treatment plants to further recycle the sewage, Zhao said.
Zhang Xiang, a researcher from Nature University, an environmental protection NGO in Beijing, said recycled water use should be promoted, especially in water-scarce cities such as Beijing. Setting up more recycled water plants in the capital will not only promote efficient water use, but also reduce costs because recycling water is much cheaper than transferring it over long distances,
he said.
According to the Beijing Water Authority, the capital will set up 46 more recycled water plants citywide in the next three years while upgrading 20 sewage treatment plants.
The treatment rate of domestic sewage in downtown Beijing will reach 98 percent by the end of 2015, it said.
The capital's recycled water is mainly used for industry, landscaping and cleaning, Zhang said.
Many new communities in southern Beijing are equipped with a network to recycle water.
In the past, people were not enthusiastic about using recycled water. However, as the government has boosted the quality of recycled water and set up more recycled water plants, more residents are gradually accepting it.
Residents in southern Beijing will also enjoy more clean energy, as the government will replace traditional coal-burning stoves with electric radiators as part of a three-year plan to develop southern Beijing from 2013 to 2015.
Since 2010, Beijing has taken measures to develop its southern areas. Earlier efforts have seen the region, which used to rely heavily on low-end industries such as cement factories and small coal mines, being turned into a bustling commercial center and home to many educational institutions.
71.This passage may appear in ________ section.
A .business B. life C. politics D. forum
72. which statement is true according to the passage
A. Recycled water will be mainly used for drink.
B .As usual, recycled water is accepted by people.
C. Traditionally people in southern Beijing use coal-burning stove for cooking.
D. The water Transferred over long distance is cheaper than recycled water.
73. How many recycled water plants will the capital city have in about 3 years?
A. 46.
B. 20
C.3
D. 49
74. What does the last paragraph mainly tell us?
第8页共13页
A. Southern area in Beijing has taken on a new look.
B. The southern area is hone to many educational institutions
C. Southern area in Beijing is more beautiful now.
D. Southern area in Beijing is a busy place now .
75. Which is the best title for the passage?

【1】The air was pleasant and the music was loud in the vast square in front of the New York State office building in Harlem(哈莱姆，美国纽约市黑人居住区) as health advocates（支持者，提倡者）set up information tables for Harlem wellness Week. It was a wide-ranging effort to educate people about non-communicable diseases: Heart disease, cancer, lung disease, obesity, and so on.
【2】There is an economic effect caused by these diseases, especially in Harlem, one of the city’s poorest districts. Without healthy employees and healthy customers, you cannot have healthy business, says Patricia Ricketts of the Greater Harlem Chamber of Commerce, which sponsors Wellness Week.
【3】Dr. Jo Ivy Boufford is president of the New York Academy of Medicine, a Wellness Week partner. She says education about better nutrition is important, but that people with low incomes often lack the means to put what they know into practice. But there is hope. New York is very active in adovating good, effective public health policies. ―New York City has banned smoking in public places, both indoors and outdoors. That is a fantastic example of what can be done, without having any impact on the economy. It is a city where you have bike paths. That is a good message for the world, because bikes make your transport active. That is good for your health and lowers air pollution,‖ she said.
【4】―It is not enough to focus on the management of disease through medication,‖Dr. Boufford says. ―That’s why health advocates will be trying to persuade UN officials during Wellness Week to pass resolutions that deal with road and transport design and construction and other potential causes of non-communicable diseases.‖

南昌凭借其江西中部偏北，赣江、抚河下游，鄱阳湖西南岸独特的地理中心位置和交通枢纽位置发展成为江西的省会。作为一个省会城市其发展和衰弱也与省份的经济情况息息相关，随着省内经济的发展而发展，衰弱而衰弱。 一、历史沿革及行政区划 南昌市因南方繁荣昌盛得名，又可称洪城、英雄城，是江西的经济、政治、文化、科技和交通中心，历史上也一直是地区的行政中心。南昌有两千两百多年历史，相传南昌城（汉豫章郡城）是汉高祖6年灌婴所建，城址在今南昌火车站东南约4公里的黄城寺，城周长十里八十四步。所以南昌城又被称为灌婴城。现代南昌是中国首批低碳试点城市，曾荣获国家创新型城市、国际花园城市、国家园林城市、国家卫生城市、全球十大动感都会等等荣誉，2006年被《新闻周刊》评选为世界十大最具经济活力城市。 截至2013年，南昌市下辖东湖区、西湖区、青云谱区、青山湖区、湾里区5个市辖区以及南昌县、新建县、进贤县、安义县4个县。其中市辖区下辖红谷滩新区、高新区、南昌经济开发区、小蓝经济技术开发区、桑海经济技术开发区、望城新区。共有29个街道、47个镇、33个乡，499个社区、1141个行政村；其中市辖区共有29个街道、10个镇、2个乡，389个社区、167个行政村。全市户籍总人口510.08万人，非农业人口235.96万人，常住人口518.42万人，出生率12.98‰，死亡率6.19‰，自然增长率6.79‰。 二、南昌的地理环境 南昌位于北纬28°10'至29°11'、东经115°27'至116°35'之间，地处江西中部偏北，赣江、抚河下游，鄱阳湖西南岸。南昌属于亚热带湿润季风气候，夏炎冬寒，雨热同期，夏季炎热有火炉之称。全境山、丘、岗、平原相间，其中水域面积达2204.37㎞2，占29.78%，在全国省会及以上城市中排在前三位。平原占35.8%，东南平坦，西北起伏，水网密布，湖泊众多。 南昌水网密布，赣江、抚河、玉带河、锦江、潦河纵横境内，湖泊众多，有军山湖、金溪湖、青岚湖、瑶湖等数百个大小湖泊，南昌市市区湖泊主要有城外四湖：青山湖、艾溪湖、象湖、黄家湖（含礼步湖、蝶子湖），城内四湖：东湖、西湖、南湖、北湖。城在湖中，湖在城中。南昌的5个市辖区就有3个名字里有“湖”字。 三、南昌的产生与发展与衰弱 提到南昌的城市发展就不能不提到赣江，赣江是长江的第七大支流，同时是江西省最大的河流。西源章水是出自广东省毗连江西赣州南部的大庾岭，东源贡水是出自江西省赣州市石城县的赣源岽，在赣州章贡区汇合称赣江，“赣”字即章贡两字的合写，赣江至鄱阳湖吴城进入长江。赣江流贯江西全省，长758公里，有大小支流2000多条，流域8.16万平方公里，为沟通江西省内运输、交通的大动脉，故江西也简称赣。赣江曾是连通长江水系和珠江水系的重要通道，是中原地区及长江流域与两广联系的重要水道，发达的商业使得江西省曾成为最发达的省区之一。 赣江是连接中原和东南沿海的重要水上路线，战略地位十分突出。故江西早期发展曾依托于战争。始皇二十六年(前221年)，秦始皇正式开始对征服百越的大规模军事行动，大将尉唯率十余万人分东西两路进军百越，最终秦统一了闽东和岭南地区，也推动了这些地区的 江西省南昌市八一中学2013-2104学年高二下学期期末考试生物试题 第一部分选择题

在历史脉络中，“运河”名称的由来与变化，是不同历史节点所勾连的历史进程的反映。汉代有“漕渠”名称出现，至隋唐时期，具有漕运功能的人工河多被称为漕渠，又因该时期“河”字已不再是黄河的专称，所以“漕河”一词也出现了，用来指称漕运河流。宋代“漕河”名称广泛使用，但同时“运河”一词开始出现，《四库全书》所列宋代文献中有94 种使用了“运河”的名称。“大运河”的概念也首次在南宋江南运河段出现，这里所说的大运河指的是江南运河。可见，这一时期，运河已然成为一个特有名词，指称某段人工河，但前须加地名指代。值得注意的是，从文献所记录的名称分布来看，“运河”一词多出现在江淮和江南区域，包括龟山运河、扬楚运河、浙西运河等。 元明清时期“运河”开始指称南北贯通的京杭大运河，元代已有“运河二千余里，漕公私物货，为利甚大”的说法，但使用并不广泛。《明史》仍称运河为“漕河”，明代其他专书、地方志等也多用漕河之名，如《漕河图志》《万历兖州府志·漕河》等。事实上，《明史·河渠志》《清史稿·河渠志》中，都列“运河”专篇，指北至北京、南至杭州的运河，但两者又有不同，前者列运河篇，但称“漕河”，后者则直接称运河：“雍正四年官方正式设置北运河的管理机构后，多使用通惠河、北运河、南运河和江南运河等说法。近世以来，民间则往往将其称为“京杭运河”或“大运河”，2014年运河“申遗”过程中，又将隋唐、浙东两段运河与京杭运河合称为中国“大运河”。 运河名称的变化反映了运道及其背后时势发展变化的趋势，首先，漕运是运河的基本功能，以“漕”为核心的漕河或漕渠的名称无疑都突出了这种功能，同时，“运河”一词也并未脱离漕运的主旨，而是以“运”字突出了“漕”的状态。其次，漕河、运河等名称都经历了从地方专称到南北通途或地方河流专称的变化过程，这个过程不仅是中国社会发展的过程，而且也是运河附属功能逐渐增加和社会交流日渐频繁的过程。“运河”一词在宋代出现似非偶然，比之隋唐时期，运河在保留漕运功能的同时，贸易交流的职能进一步加强，尤其是南宋时期，浙东运河、浙西运河是其经济命脉，浙东运河还主要承担了对外贸易的功能。 运河名称的起源、变化，在一定程度上凸显了中国社会特殊的运行与发展轨迹。运河的“运”字本意为运输，但在社会体系之中，借助水的流转，“运河”成为漕粮运输、文化传播、市场构建和社会平衡的载体；在文化体系中，运河之运又与传统社会的国祚、文脉紧密相连。在这个意义上，大运河既是一条河，更代表了一种制度、一个知识体系和一种生活方式。运河及其流经的线性区域所孕育的文化既是中国传统文化的一部分，也是形塑中国文化的基因之一。
