【题文】阅读下面的材料,根据要求写作。

美国全球语言研究所最近公布了21世纪全球十大新闻,中国作为经济和政治大国的崛起排在第一位,是新世纪的最大新闻。

该所跟踪全球75万家主要纸媒体、电子媒体和互联网进行调查,结果显示:有关中国崛起的新闻已经播发了3亿次。

对于中国的巨大变化,其中最值得展示的突出变化又是什么呢?据《中国青年报》和新浪网在中国网民的调查,得票率依次是:“经济成就”、“国际影响”、“民生改善”、“科技水平”、“城市化进程”、“开放程度”。

对于中国的这些变化,你有什么所见所闻所思所感?要求选好角度,确定立意,明确文体,自拟标题;不要脱离材料内容及含意的范围作文,不要套作,不得抄袭,不少于800字【答案】爱你,我终生的选择为什么我的眼里常含泪水?因为我对这土地爱得深沉。

每当那一轮红日从东方冉冉升起,每当那一片旗帜在晨风中飘然扬起,我都会默默对自己说:爱你,我爱你。

温柔如你,如柳的爱抚,如被窝的温暖,你给远方的赤子最温柔的爱。

建国初期,西方列强对你虎视眈眈,不仅军事上威胁,经济上封锁,连你的幼子也不放过!当太平洋那端传来你的孩子——钱学森、钱伟长急切的求救,你丝毫也不曾耽搁地发出你深切的呼唤,毫不犹豫地展开了你温暖的怀抱。

终于,怀抱赤子忠心的游子回到了最爱的母亲身边。

傲岸如你,如山的雄伟,如钢铁的臂膀,你给热血的华夏大地撑起一片不屈的天堂。

没有人会想到曾经的盟友也会背叛,没有人会想到曾经的帮助也会变成刺你的剑。

当苏联背信弃义的撤走全部援华物资和专家,当苏联苛刻地要求返还所有已耗尽的粮食果菜,你挺了挺本就坚挺的脊梁,担着这分外沉重的担子,领导你的人民走上了偿还外债的艰辛旅程。

即使如此,你也从不曾放弃你传承五千年的傲岸,从未放弃你与生俱来的傲岸不屈!飞腾如你。

如鹰的不羁,如火车的长鸣,你给贫弱的经济带来翻天覆地的巨变。

从建国初的一贫如洗,到现在的全球第二大经济体;从只能建造土坯木房到成功研制出战斗力极强的“歼-20”战斗机;从九十年代的“中国制造”到如今的“中国智造”的华丽转身,你成就的何止是一国的梦想啊,真正堪称是一个世界的奇迹!正如艾青所言:为什么我的眼里常含泪水?因为我对这土地爱得深沉。

【全国百强校】黑龙江省双鸭山市第一中学2017-2018学年高一下学期开学考试政治试题(解析版)

双鸭山市第一中学2017-2018学年度下学期高(一)政治学科开学考试试题选择题(在每小题给出的四个选项中,只有一项最符合题意,每小题2分,共50分)1. 2017年“十一”黄金周里,自由行、深度游、周边游成为游客青睐的旅游方式。

针对游客旅游方式的转变,众多旅游公司推出“个性化定制”服务,如极地探险、户外拓展、特色游学、医疗体验等,价格基本都在万元以上,并且销量可观。

下列对旅游公司提供的“个性化定制”服务理解正确的是( )①是使用价值和价值的统一体②只有使用价值,不是商品③凝结了无差别的人类劳动④是无形的,商品价值无法实现A. ①②B. ②④C. ①③D. ③④【答案】C【解析】旅游公司提供的“个性化定制”服务能够满足消费者个性化需要,是用于交换的劳动产品,凝结了无差别的人类劳动,是使用价值和价值的统一体。

①③项符合题意;旅游公司提供的“个性化定制”服务不仅具有使用价值,而且有价值。

服务虽然是无形的,但它用于交换,所以价值是可以实现的。

②④项说法错误;正确选项为C。

【点睛】商品是用于交换的劳动产品。

商品的两个基本属性是使用价值和价值,价值是凝结在商品中无差别的人类劳动。

使用价值是商品能够满足人们某种需要的属性。

His father, Johann Beethoven, also a musician, wanted his son to be a genius and encouraged him to develop his musical talents. Johann was so determined to make his son into a successful musician that he would pull poor Ludwig out of bed in the middle of the night and force the young boy to practice piano until the early hours of the morning.At the age of eleven, Ludwig van Beethoven received professional piano and composition training in Bonn, and within ten years he became well known in Vienna for his imagination when creating music on the piano. He continued to live there and became very interested in the construction of pianos, which developed into the modern grand concert piano.Things changed for Beethoven in 1798 when his hearing was becoming impaired. He composed the First Symphony and Septet Op 20 and performed them on April 2, 1800, and it won great success. However, his hearing continued to worsen, and he began to separate himself from his family and friends in order to avoid conversation.After the performance of his Ninth Symphony, he turned around to see the warm applause of the audience and broke down in tears when he realized that he couldn’thear them. Fighting against depression (抑郁) and a disorder, Beethoven continued to produce music by using special equipment that helped him to hear his symphonies. This equipment was a thin stick connected with the soundboard of his piano. Biting it, he was able to feel vibrations (震动) of sound. The music that he created during this period was filled with heroism and struggle, and went on to become his most famous compositions.4. Why did little Beethoven play piano at the midnight?A. He showed musical talents for music.B. He was interested in playing the piano.C. His father pushed him to practice his musical skills.D. He was determined to realize his music dream.5. What does the underlined word “impaired” in Paragraph 3 mean?A. Recovered.B. Constructed.C. Damaged.D. Developed.6. Why did Beethoven get separated from his family?A. He didn’t want to talk with the m because of his worsening hearing.B. He had to receive treatment because of his depression.C. He was busy in composing the First Symphony and Septet Op 20.D. He had to fix his attention on practicing piano.7. What do we know about Beethoven’s most fam ous compositions?A. They were played by special equipment.B. They reduced depression and the disorder of Beethoven.C. They were composed before Beethoven went deaf.D. They were filled with heroism and struggle.CA typical school day in the UK starts around 8:30 am. This is often even earlier elsewhere in the world, with students sitting down to their first lesson at 7:30 am in the US. The average teenager ideally needs eight to nine hours’ sleep each night, but in reality a lot of teenagers struggle to get this much. A lot of the problems arise because our sleep patterns are not fixed, and they change as we grow.So a later school start time could help to solve this problem, by ensuring toget their eight plus hours of sleep and react properly to their body’s natural rhythms (规律). There has been a general shift over the past 25 years to shorten the school day. This is not at the cost of teaching time (which has remained constant) but at the cost of natural breaks, which has led to reduced lunch time and lesson breaks.Later start times could help teens’ grades and health. This is mainly because it makes the management of children easier. Supervising (监管) hundreds of children “playing” requires effective staffing (人员配备). And there is always the fear that behavior worsens during breaks. So the theory goes that having them in class and strictly supervised must be better.But this means that students barely have enough time to absorb what they were doing in maths before suddenly they are thrust into ancient history. And teaching staff also transit from one class to another, with hardly a rest or time to refocus.Clearly rethinking the school day could benefit everyone involved. Anyway, it could also lead to better achievement in teenagers and less of a struggle for parents in the mornings. For teachers, it could also mean a less stressful day all around and what could be better than that?8.How do schools often shorten the school day?A. They reduce children’s lunch time and lesson breaks.B. They reduce the teaching time.C. They properly adjust children’ natural rhythms.D. They increase more holidays.9. What’s the purpose of the children’ short lesson breaks according to the text?A. To supervise children more easily.B. To make children quickly take in what they. Learned.C. To reduce children’s excitement.D. To make children behave better in class.10. What can we learn about later school start time from the text?A. It will add to the teacher’s pressure.B. It has always been there for25 years.C. Parents may support it.D. It benefits the students only.11. What can be the best title for the text?A. The benefits of a less stressful day.B. The benefits of later school start time.C. How to solve teenagers’ sleep probl em.D. The reasons why teenagers sleep differently.DLooking fashionable feels good. However, did you know that doing so could be extremely bad for the planet?Making clothes requires lots of energy. For example, cotton fields have to be watered. Jeans must be dyed (染色) and then dried. According to scientists, making 1 kilogram of clothes produces 23 kilograms of greenhouse gases on average.However, clothes are spending less time in shops and at homes than ever. Consumers (消费者) today keep almost every article of clothing only half as long as they did 15 years ago. That causes a large amount of waste.Some clothing companies and designers have realized this problem. H & M, for example, was the world’s largest buyer of “better cotton” last year. The cotton needs less water to grow. It also requires fewer pesticides (农药). The Swedish brand has also stopped using a chemical that pollutes the environment when making waterproof (防水的) clothes. Nike, meanwhile, has invented a new method of making shoes. It reduces waste by 60 percent compared with traditional cutting and sewing.More long lasting clothes could help, too. Tom Cridland is a British designer. The clothes that he designs all go through a special treatment. Cridland says they can last more than 30 years.Unfortunately, not all clothing companies and designers, think they should be responsible for the environment. Some companies do not care about their carbon footprint at all.What can we do? In some western schools, students are encouraged to fix their jackets and trousers. Clothing companies there send vans to campuses to help them do it. Another solution is to think twice the next time we buy new clothes. Someclothes may not look very fashionable, but they could be good for our planet.12. According to the passage, making 50 kilograms of clothes produces about kilograms of greenhouse gases.A. 23.B. 115.C. 230.D. 1,150.13. What is the difference between “better cotton” and traditional cotton?A. “Better cotton” can grow without water.B. “Better cotton” grows faster than traditional cotton.C. “Better cotton” is more environmentally friendly.D. “Better cotton” is more productive than traditional cotton.14. In order to protect the environment, what have some clothing companies and designers been doing?① Usin g new material. ② Helping students mend clothes. ③ Measuring their carbon footprint.④ Designing clothes that can last longer.A.①②③B.①②④C.①③④D.②③④15. What does the author advise us to do in order to help protect the environment?A. To stop buying clothes;B. To wear fewer clothes at home.C. To ask clothing companies for help when our clothes are torn.D. To buy clothes made by companies that care about their carbon footprint.第二节(共5小题;每小题2分,满分10分)根据短文内容,从所给的选项中选出能填入空白处的最佳选项。
