高二语文周日测试一、现代文阅读(9分,每小题3分)阅读下面文段,完成1~3题。
根据史料记载来看,富民不仅向佃户提供土地、耕牛、种子、农具及其他生产生活资料,投入大量生产成本,而且对生产过程也非常关心。
苏洵说富民对佃户“鞭笞驱役”,应有言过其实者,但其所反映的富民驱使督促佃客耕种土地,并对相关生产活动进行管理,则应是租佃制下富民群体之共同行为特征。
胡宏言,“夫客户,依主户以生,当供其役使,从其约束者也”。
其所谓“约束”者,当是指富民主户对客户的日常管理。
他还列举了一些不从“约束”的表现,其中一条便是“习学末作,不力耕桑之业”。
由此可见富民对佃客的日常“约束”,一个重要的方面就是对其生产过程进行管理与监督。
这还可用宋代官田出租的“监庄”之制观照加以说明。
官府将系官之田出租给佃户,招募上三等富户充当“监庄”来进行监督与管理,并可影响到其秋成收入;官府根据所收秋成之多寡推赏,实质是对富民“监庄”之功效高低的酬奖;官府只招上三等富户充当监庄,说明富民已具备相关“监庄”之经验,而其经验的获得,当与他们对其私有庄田出租管理的实践密不可分。
进而言之,富民将私田出租,其监督与否及管理水平之高低,应同样会影响其收成之多寡,也就决定了富民一般会对其佃户生产进行“监庄”性质的管理。
实际上,富民对佃客生产过程实施的监督与管理是全面而细致的,包括收获环节也不放过,即使遭遇酷暑天气时也是如此。
正因为富民参与到生产活动的各个环节,其田“种之常不后时,而敛之常及其熟。
故富人之稼常美,少秕而多实,久藏而不腐”,提高了粮食产量与品质,增加了收成,与“种之常不及时,而敛之常不待其熟”,由此难获“美稼”的少地自耕者形成鲜明对比。
从佃客方面来讲,虽然取得完整的土地佃权进行经营是其根本利益之所在,但由于其贫困的经济状况,需要富民“借贷赒给无所不至”,甚至“借贷种种,与夫室庐牛具之属,其费动百千计,例不取息”。
而富民关心佃户的生产生活条件,“本望租课,非行仁义”,为保证其收成所得,他们往往要考虑对佃户的生产过程进行干预,迫使佃户接受一些影响其自主经营的契约条款。

Gu also organizes a small workshop to teach knitting (编织) to children.Artist Wang Xuejun sets up a stainless-steel mirror at the mall's gate leading to Zizhong Lu. Visitors, including men, are invited to put on lipstick and kiss the mirror, thus kissing themselves.The Beast Floral Shop, a flower shop in Shanghai, contributes two walls of flowers that are made into the shape of a book, named Kiss Book. Artifacts (⼿⼯艺品) of bees and butterflies are fixed among the blossoms, kissing the flowers. The work represents love and harmony in nature.Architect Ma Ke creates a Kiss Bridge with transparent (透明的) acrylic boards and ceramic (陶瓷的)fishbowls. Bridges are often spots for dating lovers in traditional Chinese folk stories and the goldfish in the bowls are witnesses of the lovers' kisses.In the south plaza, an18-meter-high interactive tree-shaped light equipment encourages people to kiss. Each kiss turns a certain light on, reminding audiences of their sweet childhood memories of kisses.At the side of the tree is a counter, in which each kiss is counted and represents a donation to charity organizations.21. What is the main idea of the article?A. It tells people how important kisses are to life.B. It describes what Shanghai Xintiandi Style Mall looks like.C. It introduces an exhibition under the theme “kiss”.D. It introduces various activities in Shanghai Xintiandi Style Mall.22. What does the underlined sentence in Paragraph 2 mean?A. people encourage themselves to express their emotions.B. people discourage themselves from expressing their emotions.C. people teach themselves to express their emotions.D. people learn a lot from expressing their emotions.23. What can we learn from the article?A. Most people are interested in Jiang Shan’s artpiece, which brings about a feeling of warmth.B. Most visitors will kiss each other in front of the stainless steel mirror at the gate.C. All the decorations in the mall are aimed at encouraging lovers to express their love bravely.D. The 18-meter-high interactive tree-shaped light equipment will be on for each kiss.24. The article above probably is taken from a ____________.A. text bookB. science and technology magazineC. news websiteD. travel leafletBMarc Briol started his career at the age of 17 as an apprentice (学徒) at a hotel in Germany, but his experience in the kitchen started at 12, when he had to cook his own meals after school. The young chef with Belle-Vue, the European restaurant at the Grand Hyatt Shenzhen, believes a chef has to be honest and true to his food."If you look at the plate, it says exactly what I have done. You cannot cheat. If you try to take a shortcut, you will affect the taste," he says. "It is also what I appreciate in my job ---- direct communication with my customers."At just 23, Briol was appointed chef of Belle-Vue in September, when his enthusiasm and inspiration won recognition."I am so pleased to welcome Marc to lead the culinary (烹饪) team at Belle-Vue. His creativity and passion will bring new inspiration to the restaurant, and create exciting dining experiences that are approachable and fun," says Martin Riehl, executive chef of the hotel.Briol creates and combines classic dishes with his own understanding and his signature dishes are featured in the Best of Belle-Vue selection. Most of the dishes are presented in two colors ---- green and red."It is a nice contrast with the white plate at the moment. And it reminds me of something happy and merry."The colors are updated according to season, and also on request from regular customers. Although Briol has only been in Shenzhen about three months, he has fallen in love with Cantonese food."I love dim sum ---- all the steamed vegetables, chicken soup and black tea."One interesting thing about Shenzhen is how people treat food, he says. "If you go to the local market, you will see things such as snakes, which would belong to the zoo back in my country."He says that in China, everything has a reason. People respect food, which is not always done in Europe."In China, if you eat something, it is because it is healthy for your body."As for the cooking, he says, it is not easy to get raw materials for a European restaurant in Shenzhen."It took me about a month to get the fish I want for my cooking. We had to call Shanghai or Hong Kong to ship the food here," he says. "When I worked in London, the process was much easier."He gets much of his inspiration from food blogs and friends."About 80 percent of my friends come from restaurants, and they are bakers, chefs. We will meet and talk to get new ideas for food." Other sources of inspiration are traveling and cookbooks.During his day off, he will also try to explore new restaurants in Shenzhen."Food is all my life. You have to pay lots of effort to get it done, to improve yourself."25. Marc Briol has ever worked in _________ according to the article.A. France, Germany and ChinaB. Germany, England and ChinaC. France, China and EnglandD. Germany, England and France26. Which sentence can best reflect that Marc Briol loves his career?A. “If you look at the plate, it says exactly what I have done.”B. “It’s also what I appreciate in my job ---- direct communication with my customers.”C. “It’s a nice contrast with white plate at the moment.”D. “Food is all my life.”27. Why is Martin Riehl pleased to have Marc Briol lead the culinary team at Belle-Vue?A. Because he appreciates Marc’s enthusiasm and creativity.B. Because Marc has much experience in cooking.C. Because Marc is honest to his food.D. Because Marc was an appointed chef.28. Marc Briol gets much of his inspiration from many sources EXCEPT ________.A. food blogsB. travelingC. cookbooksD. food colorsCChina faces $176bn bill to clean up air pollutionCleaning up China’s air pollution will cost 1.75 trillion yuan ($176b) between2013 and 2017, a high-ranking environmental official has estimated.Wang Jinnan, deputy head of the Chinese Academy for Environmental Planning, said that the investment ---- part of an anti-pollution "action plan"announced by China's cabinet in September ---- “would drive up GDP by nearlytwo trillion yuan ($202b) and create over two million jobs,” China’s official newswire Xinhua reported.The total cost will be higher than the 2012 GDP of most countries, including Finland, Israel and Portugal.“36.7 percent of the investment, or 640 billion yuan ($64.5b) should go on cleaning up industry, followed by 490 billion yuan (28.2 percent) on cleaner energy sources. Cleaning up motor vehicles will absorb 210 billion yuan,” Xinhua re ported, citing (引⽤) Wang.In 2013, broad areas of China recorded their highest air pollution levels in 52 years, causing widespread anger over the massive environmental disaster shaped by decades of unchecked economic growth.While Beijing has long been known for its pea-soup air, a number of traditionally clearer cities, including Shanghai and Harbin, have registered pollution levels high enough for local authorities to ground flights, close schools and pull cars from the roads.On Friday, Shanghai’s con centration of airborne PM 2.5 – particulate matter small enough to stay deep within the lungs –rose to 214 micrograms per cubic meter, three times China’s national limit. The official Shanghai Environmental Monitoring Center warned children and the elderly to stay indoors.In its five-year action plan, China's State Council promised to reduce the level of airborne particulate matter by at least 10% in major cities by 2017.Yet many smog-related government measures, such as controlling street-side barbecues, have drawn criticism for polishing over the problem. In October, one Beijing official blamed the smog on “the traditional way of cooking Chinese dishes.”In response, many Chinese people have taken measures into their own hands. Face masks have become a fashionstatement; air purifier sales have rapidly increased. An elementary school in north China’s Shijiazhuang, one of the country’s most polluted cities, has begun teaching its students a smog-defying aerobics (健美操) routine involving acupuncture points associated with respiratory(呼吸)health. Last week, a hospital in the southwestern Chinese city Chengdu opened a “smog clinic” to treat air pollution-related diseases such as coughs and asthma; it has been treating roughly a dozen patients a day. "We should not fear smog. It's preventable and curable," says a poster hung by its entrance.29. What is the major cause of the heavy smog in China according to the article?A. The investment in an anti-pollution "action plan" is not enough.B. The economic development has not been carefully checked in the past years.C. Environmental Planning has not been carried out for decades of years.D. The traditional way of cooking Chinese dishes has produced too much smoke.30.

After reading the article, most readers may feel ___________.A. Angry but hopelessB. Tired and indifferent (漠不关⼼)C. Concerned but positiveD. Depressed and annoyedDHi, everybody. Over the past couple months, most of the political headlines you’ve read have probably been about the government shutdown and the launch of the Affordable Care Act(平价医疗法案). And I know that many of you have rightly never been more frustrated with Washington.But if you look beyond those headlines, there are some good things happening in our economy. And that’s been my top priority(优先考虑)since the day I walked into the Oval Office.After decades in which the middle class was working harder and harder just to keep up, and a punishing recession(衰退)that made it worse, we made the tough choices required not just to recover from crisis, but to rebuild on a new foundation for stronger, more durable economic growth.Five years later, we have fought our way back. Our businesses have created 7.8 million new jobs in the past 44 months. Another 200,000 Americans went back to work last month.The American auto industry has come back with more than 350,000 new jobs –-- jobs putting out and selling the high-tech, fuel-efficient cars the world wants to buy. And they’re leading the charge in a business that has added jobs for the first time since the 1990s –-- a big reason why our businesses sell more goods and services “Made in America” than ever befor e.We decided to stop our addiction to foreign oil. And today, we produce more renewable energy than ever, more natural gas than anybody, and for the first time in nearly 20 years, America now produces more oil than we buy from other countries.We decided to fix a broken health care system. And even though the task has been rough, so far, about 500,000 Americans gain health coverage starting January 1st. And by the way, health care costs are growing at the slowest rate in 50 years. And one more thing: since I took office, we’ve cut our deficits (⾚字) by more than half. And that makes it easier to invest in the things that create jobs –-- education, research, and so on.Imagine how much farther along we could be if both parties were working together. Think abo ut what we could do if the few didn’t hold the economy hostage (⼈质) every few months, or waste time on dozens of votes to repeal the Affordable Care Act rather than try to help us fix it.In the weeks ahead, I’ll keep talking about my plan to build a bette r bargain for the middle class. Good jobs. A good education. A chance to buy a home, save, and retire. And yes, the financial security of affordable health care. And I’ll look for any willing partners who want to help.Because of your hard work and tough s acrifices over the past five years, we’re pointed in the right direction. But we’ve got more work to do to keep moving that way.And as long as I’m President, I’ll keep doing everything I can to create jobs, grow the economy, and make sure that everyone who works hard has a chance to get ahead. Thanks, and have a great weekend.32. Which of the following is not the reason for people’s frustration with the government?A. The government shutdownB. Unemployment rateC. The addiction to foreign oilD. Cancelling the Affordable Care Act33. Why does the president mention more goods and services “Made in America”?A. To show that American goods and services are very popular.B. To indicate that American people should be dependent on themselves.C. To show that the employment rate has been increased.D. To show that American auto industry enjoys high technology.34. What’s the meaning of the underlined word “repeal”?A. put an end toB. try hard to fixC. make strongerD. get accustomed to35. According to the speech, which of the following can be implied?A. American people have every reason to feel frustrated with the government.B. Health care costs are growing at the slowest rate in 50 years.C. The president feels sorry that the economy is not moving in the right direction.D. Some government officials don’t agree with the president on the medical care system.⾼⼆英语限时训练答案完型:DABCB / CABAD / ABDCB/ DACCD阅读:A:C B D C B: B D A D C:BCC D:DCAD。
