Of course it is not the Oxford English Dictionary’s fault but we want to use another term instead of “couch potato” because potatoes are naturally healthy.”Th e OED says that “couch potato” began as American slang, meaning “a person who spends his or her leisure time sitting around, especially watching television or video tapes.”The Potato Council says its campaign is backed by dieticians (饮食学家) who say the vegetable is low in fat and high in vitamin C.Supporting the campaign, famous cook Antony Worrall Thompson said the vegetable was one of Britain’s favorite foods.“Not only are they healthy, they are also convenient and yummy (美味). Life without potato is like a sandwich without a filling,” he said.John Simpson, chief editor of the Oxford English Dictionary, said the dictionary first included the term “couch potato” in 1993 and said “dictionaries just reflect the words that society us es.”Simpson said words were never taken out of the full-length dictionary, which includes some 650,000 words in 20 volumes.But little-used words can be removed from the smaller dictionaries to make way for newer ones.“If society stops using words then they get taken out of the smaller dictionaries,” he added. The first known recorded use of the expression “couch potato” was in an article in Los Angeles Times, in 1979, Simpson said.Nigel Evans, a member of Parliament for the Ribble Valley in Lancashire, has made a motion in support of the campaign, highlighting the nutritional value of the British potato.60．British potato farmers wanted to _________.A．advertise their producesB．call for a higher price for their potatoesC．remove the expression “couch potato” from the dictionaryD．let people know how important the potato is in people’s lives61．The farmers think that _________.A．potatoes have had a bad imageB．Potatoes are good for people by natureC．potatoes sometimes do harm to peopleD．it’s the dictionary’s fault to use the expression “couch potato”62．John Simpson thinks that _________.A．the expression can be taken out of every kind of dictionaryB．dictionaries do not necessarily reflect the words the society usesC．little-used words can remain in the smaller dictionariesD．it is impossible for them to take the expression out of the dictionary63．What is wrong with the expression “couch potato” according to the farmers in this passage?

It is only when people try to live on a very restricted diet, say that when trying to lose weight, that it is necessary to make special provisions to supply the missing vitamins.An example of the dangers of a restricted diet may be seen in the disease known as"beri-beri", which used to make large numbers of Eastern people who lived mainly on rice suffer. In the early years of last century, a Dutch scientist named Eijkman was trying to discover the cause of beri-beri. At first he thought it was transmitted by a germ (病菌) . He was working in a Japanese hospital, where the patients were fed on polished rice which had had the outer coverings removed from the grain, it was thought this would be easier for weak and sick people to digest.Eijkman thought his germ theory was proved when he noticed the chickens in the hospital yard, which were fed on remains from the patients' plates, were also showing signs of the disease. He then tried to separate the germ, which he thought was causing the disease, but his experiments were interrupted by a hospital official, who ordered that the rice without coverings, even though left over by the patients, was too good for chickens. It should be recooked for the patients, and the chickens should be fed on cheap, rough rice with the outer coverings still on the grain.Eijkman noticed that the chickens began to recover on the new diet. He began to consider the possibility that eating unmilled rice (糙米) somehow prevented or cured beri-beri--even that a lack of some ingredient (成分) in the coverings may be the cause of the disease. Indeed this was the case. The element needed to prevent beri-beri was shortly afterwards separated from rice coverings and is now known as vitamin B. The milled rice, though more expensive, was in fact causing the disease the hospital was trying to cure. Nowadays, this terrible disease is much less common thanks to our knowledge of vitamins.68.What does the underlined word restricted mean?A. balancedB. limitedC. diverseD. complex69.According to the passage, a good mixed diet .A. is suitable for losing weightB. should be only fruits and vegetablesC. normally contains enough vitaminsD. is often difficult to arrange70.What do we know about the disease beri-beri?A. It killed large numbers of people.B. It resulted from lack of vitamins.C. It was transmitted by milled rice.D. It was caused by diseased chickens.71 .What can be the best title of the passage?A. A Good Mixed DietB. The Importance of Unmilled RiceC. The Dangers of Beri-beriD. The Importance of VitaminsEAn idea came to me, and I turned off the lights in the studio．In the darkness, I took off my shirt and took up the cello （大提琴）; it was the first time in my life I'd felt the instrument against my bare chest．I'd never thought about that; music scholars always talk about the resonating properties （共振）of various instruments, but surely the performer's own body must have some effect on the sound．As I dug into the notes I imagined that my own chest and lungs were extensions of the sound box; I seemed to be able to change the sound by the way I sat, and by varying the muscular tightness in my upper body．After improvising for a while, I started playing, still in the darkness．I heard the music through my skin．For the first time I didn't think about how it would sound to anyone else, and slowly, joyfully, gratefully, I started to hear again．The notes sang out, first like a trickle:, then like a fountain of cool water bubbling up from a hole in the middle of a desert．After an hour or so I looked up, and in the darkness saw the outline of the cat sitting on the floor in front of me, cleaning her paws and purring loudly, I had an audience again, humble as it was．So that's what I do now with my cello．At least once a clay I find time to tune it, close my eyes and listen．It's probably not going to lead to the kind of comeback I'd be thirsty for—years of playing badly have left scars on my technique—but I might eventually try giving a concert if I feel up to it．Occasionally I feel a stab of longing, and I wish I could give just one more concert on a great stage before my lights blink off, but that longing passes more quickly now．I take comfort in the fact that, unlike the way I felt before, I can enjoy playing for myself now．I feel relaxed and expansive when I play, as if I could stretch out my arms and reach from one end of the apartment to the other．A feeling of completeness and dignity surrounds me and lifts me up．72．The writer put the cello against his bare chest to ______．A．test music scholars' ideas about the resonating propertiesB．experience the effect of his body on the musical soundC．reduce his muscular tightness in his upper bodyD．check the function of the sound box73．In Paragraph 2 , the writer intends to ______．A．explain his feelings of playing before a catB．identify specific pieces of music he playedC．express his feelings of playing against his bodyD．describe the sound when he played against his body74．From the last paragraph we can infer that the writer was ______．A．optimistic B．discouraged C．nervous D．enthusiastic75．The passage is mainly about _____．A．a musician playing the cello for an audienceB．a musician's feelings when playing the celloC．a musician finding joy in playing music in a new wayD．a musician's desire to return to his former profession第四部分写作（共两节，满分35分）第一节：任务型读写（共10小题；每小题1分，满分10分）阅读下列短文，根据所读内容在文章后的表格中填入恰当的单词。

2015年合肥一模地理试卷要点
合肥市2015年高三一模地理试卷解析1.【答案】A【解析】本题考察地球运动知识点时间计算及日出日落与昼夜长短判断。
通过题目计算可知，H地昼长约为8小时40分钟，K地昼长约为10小时30分钟，且题中信息为12月22日，此时北半球昼短夜长，纬度越高昼越短，据此判断出H在K的北方。
同时根据日中时间应为地方时12点，可计算出H在120°E东侧，而K在120°E西侧。
故H在K 的东北。
【难度】中2.【答案】B【解析】考察经纬度区域定位。
由上题可知H地位于北半球中纬度，且北京时间11：31时，H地方时12：00，因此经度约为127.5°E，故选我国东北。
【难度】易3.【答案】B【解析】考察比例尺判断。
由图可见该学校长宽约1CM，根据比例尺定义可排除过大比例尺A和过小比例尺D选项。
鉴于题目所示学校相对独立，为乡村小学的可能性较大，因此B选项优于C选项。
【难度】中4.【答案】D【解析】考察等高线地形图的综合运用。
据图等高线数值可知该地地势低缓，排除①；由指向标方向可知，河流由西向东流，排除②；学校东部即为海岸线且无遮挡，因此③正确；河流等高线上密下疏，因此地势上陡下缓，④正确，故选择D。
【难度】易5.【答案】C【解析】考察知识点风向判断。
风由高压指向低压，同时受北半球地转偏向力影响，故为西北风。
【难度】易6.【答案】B【解析】考察气旋和反气旋气压分布特征及等高线判读。
由图知，乙地气压明显高于四周，因此为高压反气旋；甲地外围等压线为1030，为两侧等压线中的低值，根据等值线“大于大的，小于小的”规律可知甲为低压气旋，故选B。
7.【答案】D【解析】考察水循环各环节判断，海陆间水循环和海上内循环区分。
此题难度不大，但是题型新颖，需认真读图。
据图可知上升箭头为蒸发，下降箭头为降水，根据课本知识海上内循环水量最大，可判断右侧下降箭头21为陆地降雨，左侧下降箭头79为海上降雨；左侧上升箭头87为海洋蒸发，右侧上升箭头13为陆地蒸发。
2015年合肥一模答案
合肥市 2015年高三第一次教学质量检测语文试题参考答案及评分标准一、(9分)1.D2.C3.B4.B5.D6.D 15.D 16.B 17.A翻译：二十四年（前636）春天，秦国派人告诉晋国大臣，要送重耳回国。
晋国答应了，于是派人护送重耳回到晋国。
二月，重耳登位成为晋君，这就是晋文公。
文公派人杀了子圉[yǔ]。
子圉就是晋怀公。
这年秋天，周襄王的弟弟带，借助狄人的军队攻打襄王，襄王出逃，住在郑国。
（前635），周襄王派人向晋国、秦国通告了发生祸难的情况。
秦缪公率兵帮助晋文公护送周襄王回朝，杀死襄王的弟弟带。
二十八年（前632），晋文公在城濮打败楚军。
三十年（前630），缪公帮助晋文公包围了郑国。
郑国派人对缪公说：“灭掉郑国，其结果是使晋国实力增强，这对晋国是有利的，而对秦国却无利。
晋国强大了，就会成为秦国的忧患。
”缪公于是撤军，返回秦国。
晋国也只好撤军。
三十二年（前628）冬，晋文公去世。
郑国有个人向秦国出卖郑国说：“我掌管郑国的城门，可以来偷袭郑国。
”缪公去问蹇叔、百里傒，两个人回答说：“路经数国地界，到千里之外去袭击别人，很少有占便宜的。
再说，既然有人出卖郑国，怎么知道我国的人就没有把我们的实情告诉郑国呢？不能袭击郑国。
”缪公说：“你们不懂得，我已经决定了。
”于是出兵，派百里傒的儿子孟明视、蹇叔的儿子西乞术和白乙丙率兵。
军队出发的那天，百里傒、蹇叔二人对着军队大哭。
缪公听说了，生气地说：“我派兵出发，你们却拦着军队大哭，这是为什么？”二位老人说：“为臣不敢阻拦军队。
部队要走了，我俩的儿子在军队中也将前往；如今我们年岁已大，他们如果回来晚了，恐怕就见不着了，所以才哭。
”二位老人退回来对他们的儿子说：“你们的部队如果失败，一定是在殽山的险要处。
”三十三年（前627）春天，秦国军队向东进发，穿过晋国，从周朝都城北门经过。
周朝的王孙满看见了秦国的军队以后说：“秦军不懂礼仪，不打败仗还等什么！”军队开进到滑邑，郑国商人弦高带着十二头牛准备去周朝都城出卖，碰见了秦军，他害怕被秦军杀掉或俘虏，就献上他的牛，说：“听说贵国要去讨伐郑国，郑君已认真做了防守和抵御的准备，还派我带了十二头牛来慰劳贵国士兵。
