A 60-year-old homeless woman named Smokie has sleeping outside in dirt a few doors down from a man named Elvis Summers. Most mornings, she stops by Elvis’s Los Angeles apartment and asks if he has any recyclable materials for her. Through these conversations they struck up a friendship. One morning, Elvis saw a news article about a man in Oakland who has been making tiny houses out of deserted materials. He was inspired to put off paying a few bills so he could buy the wood and hardware to make Smokie a brand new shelter. It took him five days to build it, and now, for the first time ten years, Smokie has a place to hang the sign, “Home Sweet Home.” “I had nowhere to really build it, so I just built it in the street outside of my apartment,”Elvis told Good News Network. The local LAPD police have been super cool, and have told me they support it —as long aswe move it to a different spot every 72 hours. ” He made this pretty time-lapse(延时的) video showing how he did it. The materials ， including two locks on the front door and strong wheels for moving it around, cost him about $500. “I've met so many homeless people, good people,” Elvis said in an email. “Since I built Smokie's, I've had several people asking me to make them a tiny home and it's turned into much more than just the one house 1 wanted to build.” Although he runs an online retail store that sells EDM clothes ，he has decided to launch an ambitious project to fund more shelters. He plans to get lighter and cheaper materials —without sacrificing the strength of the house —for the next round. Rick Sassen, a branch manager, kindly donated the roof shingles and cedar supporting Smokie's house, final items Elvis couldn’t afford on his ow n. Saseen has promised to work out a deal on future building materials for the same cause. 4．What is the meaning of the underlined words “struck up” in paragraph 2? A ． Kept on. B ． Established. C ． Gave out D ． Accomplished.

China officially informed the World Trade Organization on Tuesday that it will ban the import of 24 different types of solid waste by the end of this year as part of a campaign to deal with environmental pollution and protect people’s health.

In response to growing public concerns over the potential environmental and health danger caused by the increasing amounts of solid waste imported into the country for recycling and treatment, China passed a special law in 1995 to control imports of waste materials, such as plastics, slag from steelmaking, unsorted scrap paper and discarded textile materials.

A year later, the country published a list for solid waste imports and began implementing a permit system to control the import volumes and types of waste imported.

However, due to the lack of effective supervision(监管) and the failure of relevant departments to fulfill their duties, solid waste imports have not been effectively controlled.

So far, China is the world’s largest importer of solid waste. According to the Ministry of Environmental Protection, China imported 7.3 million metric tons of plastic waste worth $3.7 billion in 2016, accounting for 56 percent of global imports of solid waste.

Correct recycling of solid waste materials is an important part of the global economy, and moderate imports of scrap plastic, scrap paper and scrap rubber products, such as vehicle tires, can to some extent, make up for China's shortage of various raw materials.

However, the lack of supervision has resulted in the country’s severe soil and environmental worsening.

Given that China’s continuing efforts to push for industrial transformation and upgradi ng have resulted in a noticeable decline in the demand for the materials recycled from solid waste imports. It is right for the country to restrict such imports for the sake of the environment and public health, and to better adapt to the changed industrial structure.

8．Why will China ban the import of some waste materials?

A．The amount of imported solid waste is increasing.

B．The demand for imported solid waste is in decline.

C．Some solid waste has damaged the environment and public health.

D．People are more concerned about the environment and health now.

9．Which phrase has the same meaning as the underlined word?

A．Carrying out. B．Putting off.

C．Calling off. D．Fighting against.

10．What is the problem when China deals with the imported waste?

A．Some imported waste is difficult to control.

B．The environment can’t afford the imported waste.

C．Some departments haven’t shouldered their duties.

D．Some useful materials are also among the solid waste.

11．What can we learn from the passage?

A．China will not rely on importing solid waste any more.

B．Solid waste plays an important part in the global economy.

C．People are against importing solid waste from developed countries.

D．Some imported waste can relieve the urgent need for raw materials.

I'll admit I've never quite understood the obsession (难以破除的成见) surrounding genetically modified (GM) (改变) crops.To environmentalist opponents,GM foods are simply evil,an understudied,possibly harmful tool used by big agricultural businesses to control global seed markets and beat local farmers.They argue that GM foods have never delivered on their supposed promise,that money spent on GM crops would be better channeled to organic farming and that consumers should be protected with warning labels on any products that contain genetically modified ingredients.To supporters,GM crops are a key part of the effort to sustainably provide food to meet a growing global population.But more than that,supporters see the GM opposition of many environmentalists as fundamentally anti-science,no different than those who question the basics of man-made climate change.

For both sides,GM foods seem to act as a symbol: you're pro-agricultural business or anti-science.But science is exactly what we need more of when it comes to GM foods,which is why I was happy to see Nature devote a special series of articles to the GM food controversy.The conclusion: while GM crops haven’t yet realized their initial promise and have been dominated by agricultural businesses,there is reason to continue to use and develop them to help meet the enormous challenge of sustainably feeding a growing planet.

That doesn't mean GM crops are perfect,or a one-size-fits-all solution to global agriculture problems.But anything that can increase farming efficiency—the amount of crops we can produce per acre of land—will be extremely useful.GM crops can and almost certainly will be part of that suite of tools, but so will traditional plant breeding,improved soil and crop management—and perhaps most important of all,better storage and transport infrastructure (基础设施) especially in the developing world.(It doesn't do much good for farmers in places like sub-Saharan Africa to produce more food if they can't get it to hungry consumers.) I'd like to see more non-industry research done on GM crops—not just because we'd worry less about prejudice,but also because seed companies like Monsanto and Pioneer shouldn't be the only entities (实体) working to harness genetic modification.I'd like to see GM research on less commercial crops,like corn.I don't think it's vital to label GM ingredients in food,but I also wouldn't be against it—and industry would be smart to go along with labeling,just as a way of removing fears about the technology.

Most of all,though,I wish a tenth of the energy that's spent endlessly debating GM crops was focused on those more pressing challenges for global agriculture.There are much bigger battles to fight.

12．How do environmentalist opponents view GM foods according to the passage?

A．They will eventually ruin agriculture and the environment.

B．They are used by big businesses to dominate agriculture.

C．They have proved potentially harmful to consumers' health.

D．They pose a big threat to current farming practice.

13．What does the author say is vital to solving the controversy between the two sides of the debate?

A．Breaking the GM food monopoly (垄断). B．More friendly exchange of ideas.

C．Regulating GM food production. D．More scientific research on GM crops.

14．What is the author's view on the solution to agricultural problems?

A．It has to depend more and more on GM technology.

B．It is vital to the sustainable development of human society.

C．GM crops should be allowed until better alternatives are found.

D．Whatever is useful to improve farming efficiency should be encouraged.

15．What does the author think of the ongoing debate around GM crops?

A．It arises out of ignorance of and prejudice against new science.

B．It distracts the public attention from other key issues of the world.

C．Efforts spent on it should be turned to more urgent issues of agriculture.

D．Neither side is likely to give in until more convincing evidence is found.

二、七选五

Most of us lead unhealthy lives; we spend far too much sitting down. If in addition we are careless about our diets, our bodies soon become loose and fatty and our systems slow moving.

16．I am thinking of such features of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport or other. While it is true that every weekend you will find people playing football and hockey in the local park, they are outnumbered a hundred to one by the people who are simply watching them.

For those who do not particularly enjoy competitive sports—17．—there are such separate activities as cycling, walking, jogging and swimming. What often happens though is that you do them in such a leisurely way, so slowly, that it is doubtful if you are doing yourself much good, except for the fact that you have at least managed to get up out of your armchair.

Even after you have found a way for keeping in shape, through sport or gymnastics, 18．, because, according to the experts, you must also master the art of complete mental and physical relaxation. 19．Yoga, as practiced in the West, is the most widely known and popular of the systems for achieving the necessary state of relaxation. It seems ironical (讽刺性的), though, that as our lives have improved in a material sense we have found it increasingly necessary to go back to forms of activity—20．—which were the natural way of life of our forefathers.

A． be active and practise Yoga

B． There are some aspects of our unhealthy lives that we cannot avoid.

C． and it is especially difficult to do so if you are not good at them

D． physical effort on the one hand and relaxation on the other

E. they spent most of the time out of doors

F. you are still only half way to good health

G. It has to do with deep breathing, emptying your mind of all thoughts, meditation, and so on.

When she saw the lamp, she picked up the lamp ___35___, running her fingers over the bowl, over the hurricane glass, and ___36___ it closely. “See this?” She pointed at a very s mall mark in the glass. “The one at home has the same mark.” She smiled. It was the first time I had seen her ___37___ smile since the doctors first found the cancer.

When the lamp ____38__ in our house, next to its mate, she cried. She went to light the lamps and sit on their glow until she could sleep.

山西大学附中高三第一学期月月考试Word版

山西大学附中2013高三第一学期8月月考试 政治试题 （考试时间：90分钟）（考查内容：经济生活为主）命题教师：张林凤 一、单项选择题（本大题共25小题，每小题2分，共50分） 1.经济学上有个古老的原理叫“劣币驱逐良币”：在铸币时代，当那些“劣币”（低于法定重量或者成色的铸币）进入流通领域后，人们就倾向于将那些“良币”（足值货币）收藏起来。结果，市面上“良币”越来越少，“劣币”越来越多。“劣币”之所以能驱逐“良币”，主要是因为（） ①作为流通手段的货币，不一定是足值的货币 ②货币是衡量商品价值的内在尺度 ③作为交换媒介，货币的名义价值与实际价值可以分离 ④“劣币”作为价值符号，能够充当商品交换的媒介 A．①③B．②③C．②④D．①④ 2. 假定2011年我国某款工艺品价值用人民币表示为1330元，美元对人民币的汇率为1美元=7元人民币。如果2012年生产该款工艺品的社会劳动生产率提高了50%，纸币流通速度提高50%，且人民币对美元升值5%，其他条件不变，按照等价交换的原则，若该款水晶工艺品以美元标价，则其价格为 A．200.5美元B．200美元C．192美元D．199.5美元 【答案】 D 【解析】纸币流通速度提高50%，表示人民币贬值,社会劳动生产率提高了50%，表示成本下降。人民币对美元升值5%，表示2010年美元对人民币的汇率1美元=7/1.05元人民币 所以该款水晶工艺品以美元标价，则其价格1330(1+50%)/(1+50%)/(7/1.05)=199.5美元3. 2012年3月份至今，各地玉米收购价格不断攀升，农民普遍存在惜售心理，企业面临收粮难困境，很多企业只好抬价“抢”玉米，不少玉米深加工企业处于微利或亏损运行中。下列说法正确的是 ①政府只有增加种粮补贴，才能控制玉米价格②玉米价格是市场竞争的结果 ③农民待价而沽违背了价值规律④企业优胜劣汰，促进资源向优势企业集中 A．①③B．③④C．①②D．②④ 4.下列曲线中（P为价格，Q为需求量），一般说来，能正确说明近期“中国大妈”抢购黄金 首饰现象的是

A.RC helps kids improve their horse-riding skills B.kids can enjoy one-to-one training at LMFL C.kids can stay at French host families at EI D.FLC was founded in 1997 in France B This weekend a marathon took place in Salzburg, the city where I’m living. I admired the runners who ran 42.2 kilometers if they finished the course. I’ve never run for more than half an hour, so I’m amazed that some peo ple manage to keep going for over four! At university I play korfball. This is a team sport with eight people on each team. The aim is to shoot the ball into the hoop(篮圈), which is like basketball hoop, only higher! All players get a chance to attack and defend during the game and it’s very fast-paced. When I started korfball, I wasn’t very good at it. I could throw and catch but I wasn’t very fast on my feet. Shooting was also difficult for me. Moreover, you often have to shoot on the move in korfball, and I found it hard to balance and shoot straight while running backwards away from my defender! However, I really enjoyed the sport and made friends in the club, so I attended training twice a week. Two years later I am in the first team for my university and have played in many matches. This just shows if you train hard, you can succeed. Running is difficult because you have to make yourself willing to keep going. I used to get really out of breath while running and I didn’t feel good at all! Now I actually enjoy going for a run along the river in Salzburg, feeling my muscles(肌肉) working and breathing in the fresh air.

宁夏银川一中2015届高三上学期第一次月考

宁夏银川一中2015届高三上学期第一次月考 高三 2013-09-08 19:17 宁夏银川一中2015届高三上学期第一次月考 语文试题 第I卷阅读题 甲必考题 一、现代文阅读(9分，每小题3分) 阅读下面的文字，完成l～3题。 夏商周三朝，被中国传统史学家称为“三代时期”。商人性格活泼，注重感官享受，殷墟妇好墓挖掘出的210件礼器中，仅酒器就有方彝、尊、献、壶，爵等15种175件，占全部礼器74%，酒器在墓葬中的批量摆置反映了商人重酒的风气。 《诗?商颂?烈祖》中强调祭祖时美酒的重要性“既载清酤，赉我思成”。张光直在《商代的巫与巫术》中提出：“酒是一方面供祖先神祇享用，一方面也可能是供巫师饮用以达到通神的精神状态。”可见早期的祭祀离不开酒，而祭祀时候的饮酒也有特别的规定，一般先由巫师或祭司饮酒，传达神灵的旨意。 上世纪80年代出土的平民墓葬中，有随葬品的均为爵、觚等酒器。商代酒器最简单的组合是一爵一觚。现代考古学家认为，这种酒器之所以命名为“爵”，是由于它的造型像一只雀鸟，前面有流，好像雀啄，后面有尾，腹下还有细长的足，而古代爵与雀同音通用。宾主酒酣耳热之时，乐舞表演将把宴会的气氛推向高潮。根据《商颂》中的描述，重要的祭礼都以舞队的“万舞”开始，伴随着鼓、管、钟、磬等乐器的伴奏，最后在盛大的宴飨中结束。被总称为“万舞”的舞蹈包括舞者手持马辔的武舞，以及脚踩双杆，类似高跷的林舞。 与商代不同，周代的酒成为了王室弘扬“礼制”与仪典的载体，饮酒聚宴往往只是繁琐而庄重的祭祀典礼结束后的附属程序。对于饮宴具体制度，《礼记》记载了很多严格要求，比如参与祭祀宴会者的身份不同，其使用的酒器也有所差异：“宗庙之祭，贵者献以爵，贱者献以散；尊者举觯，卑者举角。”祭祀之时，酒之种类不同，摆放位置也有严格繁琐的规定，比如明确要求祭典时，淡薄的酒放置于内室，甜酒在门边，浅红色的清酒在堂上，清酒在堂下。周平王东迁洛邑后，周王室对诸侯国的控制能力一落千丈，随之的春秋战国时

With more than 1,500 stands and 3,000 free parking spaces, the monthly market attracts visitors from not only the Netherlands, but Europe-wide. There is a five euro admission fee, but you can be pretty sure that you can browse second-hand treasures for most of the day. Anything and everything can be found here; old guitars and antique chairs, art prints and military gear. Noordermarkt Flea Market Saturday, 9am-4pm Monday, 9am-2pm In the centre of the Jordaan, the Noordermarkt Flea Market on Saturdays includes vintage(老式的) goods and organic food produce from local farmers. On Mondays, the market transforms into an antique-hunter’s goldmine. There are piles of vintage clothes, antique books, coins and furniture. Waterloopein Market Monday-Saturday, 9am-6pm The most centrally located of all flea markets in Amsterdam, Waterlooplein Market offers visitors a range of snacks, second-hand clothes and vintage treasures. There’s a maze of second-hand goods, from old globes and hanging lamps, to African drums, antique rugs and used bikes. Spui Book Market Friday 10am-6pm Ideally situated among bookstores, you’ll find a collection of tents sheltering second-hand and antique books at the book market on Spui. You can find a variety of literature from biographies and poetry to fantasy-fiction, history, psychology and geography. While most books are from the Netherlands, some English and international titles are for sale. As well as antique maps, prints and record.
