辽宁省庄河市高级中学2017-2018学年高二上学期开学考试英语试题满分:120分时间:120分钟一、阅读理解(共15小题;每小题2分,满分30分)AIf feels like every time my mother and I start to have a conversation, it turns into an argument. We talk about something as simple as dinner plans and suddenly, my mother will push the conversation into World War? She’ll talk about my lack of a bright future because I don’t plan to be a doctor. And much to her disappointment, I don’t want to do any job related to science, either. In fact, when I was pushed to say that I planned to major (主修) in English and communications, she nearly had a heart attack.“Why can’t you be like my coworker’s son?” she bemoans all the time. Her coworker’s son received a four year scholarship and is now earning 70,000 dollars a year as an engineer. I don’t know what to answer except that I simply can’t be like Mr Perfect as I’ve called the unnamed coworker’s son. I can’t be like him. I’m the type of person who loves to help out in the community, write until the sun goes down, and most of all, wants to achieve a career because I love it, not because of fame (名声) or salary.I understand why my mother is worried about my future major. I’ve seen my mother struggle to raise me on her small salary and work long hours. She leaves the house around 6:30 am and usually comes home around 5 pm or even 6 pm. However, I want her to know that by becoming a doctor, it doesn’t mean I’ll be successful. I’d rather follow my dreams and create my own future.1. Which of the following topics do the writer and his mother often talk about?A. The writer’s studies.B. The writer’s future job.C. Dinner plans.D. Wars around the world.2. We can infer from Paragraph 1 that the writer’s mother________.A. doesn’t want the writer to major in EnglishB. doesn’t think the wr iter should be a doctorC. gets along very well with the writerD. doesn’t think working in the science field is a good idea3. The underlined word “bemoans” in Paragraph 2 most probably means “________”.A. agreesB. shoutsC. complainsD. smiles4. Which of the following statements is probably TRUE about the writer?A. He wants to be like his mother’s coworker’s son.B. He wants to find a job in his community in the future.C. He doesn’t think his mother’s coworker’s son is perfect.D. He wants to do something he really likes in the future.【答案】1. B 2. A 3. C 4. D【解析】试题分析:本文讲述了作者和妈妈谈话时总是会将话题转到自己未来的职业上,他妈妈不想让他主修英语,而作者却想做他想做的事。

Take a look at some breathtakingly beautiful island countries in the world, which everyone should certainly visit at least once in his lifetime.MaltaMalta is a beautiful southern European country in the Mediterranean Sea, which has a rich history and culture. There are amazing sky-high cliffs to climb, splendid temples to explore and lots of wonderful places to go scuba-diving. In fact, there are plenty of interesting things to see and to do in Malta and this island country has something for everyone. The historic part of Malta is shown in its incredible architecture, great walled cities, and many underground tunnels.FijiFiji is a fabulous island that has plenty of surprises for any adventurous travelers. It is famous for the worlds best surf scenes, and many surfing enthusiasts travel to Fiji yearly to ride the great wives. Well, if surfing is not for you and you love sitting on the beach and relaxing, hiking or seeing breathtaking waterfalls, Fiji is certainly the best island country to visit.MaldivesNot only is Maldives one of the most beautiful island countries, but it is one of the most popularhoneymoon destinations. Situated in the middle of the Indian Ocean, Maldives is made up of a series of ancient coral reefs that grow up along the sides of ancient volcanoes, with fascinating beaches and luxurious resorts.1.In Malta, you can ________.A.see breathtaking waterfalls B.explore temples and tunnelsC.ride the great waves D.hike in the hills2.What is the special feature about Fiji?A.You can take a yacht free in this country.B.There are sky-high cliffs to climb,C.It is surfing enthusiasts’ favorite island country.D.If you once visited it, you wouldn’t like to go there again.3.If a newly-married couple are looking for the honeymoon destination, they will choose________.A.Malta B.FijiC.the Mediterranean Sea D.MaldivesElephants in Uganda are starting to come close to villages near national parks. The big animals are a real danger to people.So, the Uganda Wildlife Authority has been giving people new tools to keep the elephants away: vuvuzelas. They are plastic instruments some fans use at sports events.The instruments make a loud sound elephants do not like. The animals leave, and no one is harmed. A spokesperson for the Uganda Wildlife Authority says vuvuzelas work because they do not threaten the elephants. That is important because an elephant that feels threatened is more likely to attack. So far, no one has reported an elephant attacking in answer to a vuvuzela. Officials and villagers have tried other ways to stop elephants from coming near farms and houses. They have built beehives – houses for flying insects that sting. They have hung ropes covered in spicy oil. They have dug long, deep holes. And they have used guns, called A-K47s. An official from the Uganda Wildlife Authority explains that people shoot the gun in the air to scare the elephant. But over time, the elephants have stopped being afraid of the sound of the gun. They only look at the shooter and wave their ears.Another official for the Uganda Wildlife Authority, Gessa Simblicious, says one elephant-prevention solution will not work everywhere in Uganda. And one day, elephants mayaccept the vuvuzela noise, just as they do the sound of the A-K47.But right now, vuvuzelas are an effective, non-violent and fun way to deal with a serious problem.4.What’s vuvuzelas?A.New tools some fans use at sports events.B.New tool to save the elephants.C.Plastic instruments to keep the elephants away.D.Plastic instruments to threaten the elephants.5.Which of the following statements is TRUE according to the passage?A.Vuvuzelas work because they do not threaten the elephants.B.An elephants will attack human being in answer to a vuvuzela,C.Villagers have no way to stop elephants.D.The elephants are always afraid of the sound of the gun.6.People shoot the gun in the air in order to ________.A.shoot the elephants awayB.let the elephants stop being afraid of the soundC.avoid the elephants hurting peopleD.scare the elephants to leave the village7.The author believes that ________.A.elephants are not afraid of vuvuzelasB.Vuvuzelas can not stop elephantsC.vuvuzelas can solve this serious problem foreverD.elephants are used to the sound of vuvuzelas nowIt is quite reasonable to blame traffic jams, the cost of gas and the great speed of modern life, but manners on the road are becoming horrible.Everybody knows that the nicest men would become fierce tigers behind the wheel.It is all right to have a tiger in a cage, but to have one in the driver’s seat is another matter altogether.Road politeness is not only good manners, but good sense too.It takes the most cool-headed drivers great patience to give up the desire to beat back when forced to face rude driving.On the other hand, a little politeness goes a long way towards reducing the possibility of quarrelling and fighting.A friendly nod or a wave of thanks in answer to an act of politenesshelps to create an atmosphere of good will and calm so necessary in modern traffic condition.But such behaviors of politeness are by no means enough.Many drivers nowadays don’t even seem able to recognize politeness when they see it.However, misplaced politeness can also be dangerous.Typical examples are the driver who waves a child crossing the street at a wrong place into the path of oncoming cars that may be not able to stop in time.The same goes for encouraging old ladies to cross the road wherever and whenever they want to.It always amazes me that the highways are not covered with the dead bodies of these grannies (奶奶).An experienced driver, whose manners are faultless, told me it would help if drivers learnt to correctly join in traffic stream without causing total blockages that give rise to unpleasant feelings.Unfortunately, modern drivers can’t even learn to drive.Years ago, experts warned us that the fast increase of the car ownership would demand more give-and-take from all road users.It is high time for all of us to take this message to heart.8.According to the passage, troubles on the road are often caused by .A.road conditions B.the behavior of the driversC.the speed of modern life D.the large number of cars9.In the writer’s opinion, .A.unskillful drivers should be punishedB.strict traffic rules are badly neededC.drivers should show road politeness properlyD.drivers should avoid traffic jams10.The underlined word “give-and-take” in the passage means .A.politeness and impolitenessB.good manners and bad mannersC.willingness to give in to each other’s wishesD.offering help to others as much as possible11.What is the best title of the passage?A.Traffic Problems B.Road PolitenessC.Bad Manners on the Road D.Good Drivers and Bad DriversYour next Saturday night takeaway could be brought to you by a robot after a major food delivery company announced plans to use automated vehicles to transport meals. Europe’sbiggest online takeaway food company Just Eat has partnered with Starship Technologies to deliver food with robots on the streets of London later this month. “Nobody has ever done deliveries with land-based robots,” said Allan Martinson, the chief operating officer of Starship.The robot courier can travel up to 4 miles per hour for about 10 miles. It uses a GPS signal and nine cameras to navigate (确定方向). Instead of a person arriving at their door, customers could find themselves receiving a notification (通知) on their phone that says a robot is on its way and a code to unlock the automated courier. “Put the code in, the robot opens up, and there’s your food,” said David Buttress, chief manager of Just Eat.The robot, which has so far been tested in Greenwich, Milton Keynes and Glastonbury, costs .1 to transport within 3 miles, compared with the .3 to .6 it costs for a human courier. To date 30 robots have driven nearly 5,000 miles without getting into an accident or finding themselves picked on by passers-by. They have driven in more than 40 cities around the world, including London and Tallinn, Estonia.An initial worry was how the public would react to robots. But Martinson said the public has been calm when passing the delivery machine on the streets. “The most surprising reaction has been the lack of reaction,” said Martinson.Another significant fear was that people would disrupt (扰乱) the robots, or try to steal them and their contents. To prevent this, the robot is fitted with nine cameras, two way audio, and movement sensors that send a warning if it is lifted off the ground. And it opens only with a pass code provided to the customer via a notification. “It’s much easier to shoplift than it is to steal a robot,” said Martinson.12.According to the text, the Starship robot ________.A.opens up upon hearing the codeB.travels 10 miles per hour at mostC.finds its way by means of GPS and camerasD.sends a message to the customer upon arrival13.The test of Starship robots shows that ________.A.they are easy to operateB.the robot delivery is appreciated in big citiesC.the robot delivery is cheaper than human deliveryD.they can travel for 10 hours continuously14.Which of the following is one of the worries about Starship robots?A.People’s indifference to the robotsB.Safety of the robot deliveryC.Accuracy of the robot delivery _D.People’s concern about public traffic15.The purpose of the text is mainly to ________.A.describe the great improvement of Just EatB.tell about the global trend of Food CompaniesC.show new robots are to move on the roadD.show delivery robots are to replace takeaway drivers二、七选五Although most games have winners and losers, the goal of sports is not to win every game. The real goals include getting exercise, having fun, and learning important social skills, like sportsmanship.Good sportsmanship is all about respect. Good sports respect the other players on their teams. They respect the players on opposing teams. They respect coaches, and they also respect the referees or other officials involved in their games. 16. . they yell at their teammates and they talk back to coaches or referees.Kids usually learn sportsmanship--good and bad --from the adults in their lives. 17.. If parents and coaches show disrespect to other fans, referees, or each other, kids will likely act the same way on the field.18.. Some of them are very basic and easy to do, like shaking hands with other players before a game. Other examples may take a little more courage, such as acknowledging a great play made by the opposing team.Learning good sportsmanship is important because it helps you develop an attitude of graciousness(礼貌) and respect that will carry over into all the other areas of you life!19.. Being a good sport in the classroom will eventually lead to being a good sport in the workplace. So be a good sport in whatever you do! 20. . when others see you acting in a way that makes it clear that winning isn’t the most important thing, you can move on to focusing on theimportant thing, like having fun, getting exercise and improving your skills.A.Good sportsmanship can be shown in many ways.B.On the contrary, bad sportsmanship is all about disrespect.C.The example you set can be a powerful teaching tool for others.D.Player’s parents and coaches set examples that kids tend to follow.E.We can be good sports by encouraging others but not laughing at them.F.Starting as a good sport earlier will help you be a good sport as you get old.G.If you are a good sport on the field, you will also likely be a good sport in the classroom.三、完形填空Mr. Glen is a millionaire. Five years ago, after returning from abroad to his motherland, he ____his small company. Speaking of success, Glen often tells us a story about his extra expensive “school” fee.

现代实验艺术,一方面被西方媒体热炒而名播世界,另一方面现代实验艺术,一方面因被西方媒体热炒而名播世界,另一方面却在它的原产地备受冷落。
那么,到底是一种什么样的力量促成了现代实验艺术的诞生呢?从历史上看,先锋艺术在现代的出现,一个根深蒂固的动因是启蒙运动以来西方社会信仰的变化。
这种信仰在艺术领域表现得更为极端,意大利未来主义者马里内蒂曾开宗明义地讲,“未来主义就是仇恨过去”。
新型艺术家之所以事事采取与传统对抗的立场,是有被信仰裹挟的背景。
1973年,美国学者哈罗德·布鲁姆曾在其《影响的焦虑》中讲,千百年来,一切艺术的主题和技巧已被艺术家用尽,后来者要想对艺术史有所推动,唯一的手段就是否定或推翻传统。
在现代社会,日常生活的审美化改变了艺术的价值取向。
现代以来,工业革命极大地提高了人的实践能力。
人不仅可以按照美的规律创造艺术,而且可以再造现实。
也就是说,传统上仅对艺术有效的审美原则,现在已彻底被放大为对日常生活全面有效的原则。
在这种背景下,艺术创造如果仍然遵循美的规律,那么它在现代的命运就必然是被淹没的。
相反,它表现丑或震惊,则极易拉开与现实生活的距离。
就此而言,西方现代艺术表现丑,就不仅是以另一种方式与“美的艺术”对抗的问题,而且也是在已经审美化的现实中重建自身价值的问题。
语文-高二辽宁省庄河市高级中学2017至2018学年高二上学期开学考试语文
庄河高中2017年高二开学考试语文试卷第Ⅰ卷阅读题(共70分)一、现代文阅读(一)论述类文本阅读阅读下面的文字,完成下列小题。
当哪怕是表情包式表演和PS型剪辑,只要搭配上当红IP和“鲜肉小花”,就能引发收视高潮与商业成功之时,《朗读者》、《见字如面》以其真诚与直达心灵的表达方式从满屏娱乐竞技类综艺中脱颖而出,被誉为一股清流。
在中国的电视市场上,情感类节目一直是广受欢迎的宠儿。
发自内心的情感表达与倾诉,通过光影音的作用打动受众,自然而然,顺理成章。
从某种层面上来说,《朗读者》类节目的出现,在受众群中激起阵阵涟漪,并不为奇。
《朗读者》更像是用朗读串连着的人物访谈。
在每期的节目之中,有大量的访谈时间,真正用于朗读文学作品的时间并不多,而正是通过对多位有名气、有影响力的公众人物的访谈,讲述了普通人的不平凡的坚守与最朴素的情感。
《朗读者》的成功被外界解读成“出乎意料”,因为其毫不讳言自己的人文特质,“将值得关注的生命和值得关注的文字完美结合,就是我们的《朗读者》”。
但在此前,与泛娱乐节目的同台竞争中,人文类节目很少能够冲出重围、浮出水面。
在人文类节目被边缘化的大环境之下,《朗读者》的存在,成为沧海遗珠般的稀缺资源。
人文类节目的式微,并非简单地没有流量“鲜肉小花”加持,也并非是因为对情感调动得不够充分,而是因为在面对碾压式的情感综艺时,人文节目并不追求娱乐,更不持“道德中立”的态度——反之,它时时在追求一种对理想人格的阐发和尊严价值的关切。
如今的大众媒体,不追求娱乐意味着不回避严肃的问题,甚至是不盲目依从娱乐工业的逻辑,这就意味着,这种异质性的力量可能会被文化工业排斥,甚或甩出局外。
但,这恰恰就是《朗读者》的成功让人欣喜和意外之处。
对于大众媒体来说,一旦有了“道德偏向”的姿态,就需有明确的价值观为铮铮铁骨,也需超越金钱利益的顾虑,因为作为价值提供者的节目制作者,就难以用“信息提供者”的身份去隐匿自己的价值偏向而任由自己觉得错误的价值广泛传播,于是节目的内容、形态、表达与受众用户的数量都会受到限制。
