They last for the same length of time.C. The tickets can be used in any US city.D. Their opening dates are the same.BChristmas in the United States is traditionally a time of gift-giving and family gatherings. But small towns across the country have their own traditions.Middleburg, a small town in the state of Virginia, is known for its horses. For more than 50 years, Middleburg has organized a yearly Christmas parade. Men and women ride horses through the woods and fields. They follow hunting dogs as they search for a wild fox. But first, these hunters ride in the yearly parade, wearing their bright red hunting clothes and hats.John Hale, a citizen of Middleburg says many city people visit his town. “We have a lot of people from an urban area that come to visit, but it incorporates a lot of the old traditions.”The nighttime hayride is one such tradition. Small groups gather under the moonlight on an open wagon (四轮马车) filled with hay (干草). The passengers sing as farm horses pull the wagon slowly across the fields.There are some newer traditions, too. Trey Matheu works at the nearby Salamander Resort. He says a visit to Middleburg is a chance to slow down for a day. He says Middleburg can be a calming, peaceful place without tension.“Middleburg is an opportunity to take a step back, to take a deep breath, and understand that even though life is moving on at a very fast pace, there’s really an opportunity where you’re allowed to step off for a little bit.”Parade organizers say more than 13,000 people attend even in below freezing weather. But if you ask, you will hear many different reasons why people come to watch the parade:“I come here because I’m from a small town. I like how everybody comes together.”“I live right down that street, right there. And that’s my dog.”Middleburg looks its best at Christmastime. That may be why so many people return each year.24. At Christmas, people in Middleburg usually ________.A. visit friends and familiesB. ride in the annual paradeC. feed farm horses with hayD. hunt for dogs in the woods25. According to Trey Matheu, why do people visit Middleburg?A. To enjoy the fresh air.B. To escape competition.C. To relax themselves.D. To challenge themselves.26. What do we know about the small town Middleburg?A. It attracts many people each year.B. It makes a large money from tourism.C. It doesn’t respect Christmas traditions.D. It is a good place for family gatherings.27. Which of the following can be the best title for the text?A. Middleburg’s Christmas ParadeB. A Small Town Known for HorsesC. Newer Traditions at ChristmastimeD. Christmas Traditions in MiddleburgCThe world’s first “Sky Pool”has been uncoated - and it’ll give anyone a touch of dizziness, unless he or she is not bothered by heights.Situated in the capital’s new riverside district beside Battersea Power Station, the glass pool, hanging 10 storeys, or 110 feet up as a bridge between two apartment buildings, is 25 meters long, 5 meters wide and 3 meters deep with a water depth of 1.2 meters. Swimmers will be able to look down 35 meters to the street below as they take a dip, with only 20 cm of glass between them and the outside world. It’s even got a bar, folding chairs and an orange garden.The pool will be part of Embassy Gardens at Nine Elms, a huge￡15 billion building project beside the new American Embassy in south-west London. The project is creating thousands of apartments, the smallest of which are expected to cost nearly $1 million, and the pool will only be open to the apartments’owners.Embassy Gardens takes design inspiration (灵感) from the Meatpacking District of New York with floor to ceiling windows and brick frontages. The Sky Pool’s transparent structure is the result of important development in technologies overthe past ten years.The experience of the pool will be truly unique (独特的) and it will feel like floating through the air in central London.Those people lucky enough to swim there will have a perfect view of the Palace of Westminster and the London Eye. It will be a selling point for developers when the second stage of the development is released (投放) to market.28. Who can swim in the Sky Pool?A. Tourists to London.B. Anyone at Nine Elms.C. People living in Embassy Gardens.D. Those who aren’t terrified of heights.29. People lucky enough to swim in the Sky Pool can do the following EXCEPT________.A. floating through the airB. sitting in the gardenC. enjoying the sceneryD. drinking with friends30. Which of the following statements is TRUE?A. The pool lies in the centre of London.B. The pool is 25 meters above the ground.C. The pool was at the top of an apartment building.D. The pool is helpful for selling apartments in Embassy Gardens.31. We can infer from the text that ________.A. the sky pool will be part of a building projectB. the apartments in Embassy Gardens are quite expensiveC. Embassy Gardens lies in London’s new riverside districtD. Embassy Gardens looks exactly like the Meatpacking DistrictDIt’s 3 o’clock and you’ve been hard at work. As you sit at your desk, a strong desire (欲望) for chocolate overcomes you. You try to busy yourself to make it go away. But it doesn’t. Here is another situation. Perhaps you are not feeling well. The only thing you want to eat is a big bowl of chicken soup, like your mom used to make when you were sick as a child. Food cravings are a strong desire for a specifictype of food. And they are normal.Scientists at the website How Stuff Works compare hunger and cravings this way. Hunger is a fairly simple connection between the stomach and the brain. They even call it simply “stomach hunger.”When our stomachs burn up all of the food we have eaten, a hormone (荷尔蒙) sends a message to one part of the brain for more food, which controls our most basic body functions such as thirst, hunger and sleep. The brain then produces a chemical to start the appetite (食欲) and you eat. Hunger is a function of survival.A craving is more complex. It activates (刺激) brain areas related to emotion, memory and reward. These are the same areas of the brain activated duringdrug-craving studies. Because of this, some scientists call food cravings “mind hunger.”People often crave foods that are high in fat and sugar. Foods that are high in fat or high in sugar produce chemicals in the brain. These chemicals give us feelings of pleasure.In a 2007 study, researchers at Cambridge University found that “dieting or controlled eating generally increases the possibility of food craving.”So, the more you refuse yourself a food that you want, the more you may crave it. However, fasting is a bit different. They found that eating no food at all for a short period of time reduced food cravings.So, the next time you crave something very special, know that it’s the fault of your brain, instead of your stomach.32. The author describes two situations in the first paragraph to ________.A. deepen the understanding of hungerB. report the discovery of craving studyC. introduce the topic of the whole passageD. remind readers of their own special food33. What do we learn about food craving?A. It shows food is connected with emotion.B. It makes sure that a person survives hunger.C. It means the stomach functions well.D. It proves the brain decides your appetite.34. What’s the likely result of dieting?A. The drop of chemicals.B. The increase of food desire.C. The refusal of fat and sugar.D. The disappearance of appetite.35. In which part of a newspaper can you see this passage?A. Education.B. Entertainment.C. Science.D. Economy.第二节(共5小题：每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

一、现代文阅读(36分)(一)论述类文本阅读(本题共3小题，9分)阅读下面的文字，完成1～3题“囤积知识”只是学习第一步①日子好过，囤积生活用品的人变少，但“囤积信息”的人增多，理由也更充分。
看过的电影、照过的相片如同“备忘录”，记录着美好的记忆，弃之可惜；没读的书、没看的帖，偶遇就是缘分，如果不马上保存，就会在信息洪流中销声匿迹。
囤积信息几乎不占用物理空间，不会和生活起居“抢地盘”。
存储介质由1.44Mb的3.5英寸软盘扩大到空间以Gb、Tb计的硬盘、网盘，信息获取渠道从实体书报到群组网站，我们赶上了“攒资料”最便捷的时代。
②信息爆炸，意味着信息量大、信息迭代快。
所幸，信息的存储、传输能力也更强。
但除了“量变”的视角外，人们更关注信息存储方式的改变是否带来了“质变”。
有人说：信息囤积，使人们从知识的生产者成为知识的搬运工。
有人说：只存不看，人变懒，大脑也退化了。
这些说法似乎有些道理。
尤其当集纳成为一种影响生活工作的习惯以及放弃无用的物品成为一种障碍时，从心理学的角度看，有可能已经患上了心理疾病。
③但从学习的角度看，信息积累是现代社会的一门必修课。
在学科分工细化、知识快速迭代的当下，成为百科全书式的学者几无可能。
即便专攻一门，也没有谁能掌握必备的所有专业技能和知识。
老一辈学者常常通过成千上万张手写卡片积累知识；在电脑辅助人脑“记忆”的时下，“知道信息在哪里”与“知道信息是什么”同样重要。
所以，把信息囤积到手机、电脑中的“私人图书馆”，利用技术编码入库、检索查询、精准定位所需知识，日益成为公认的学习方式。

每小题给出的四个选项中，只有一个选项符合题目要求)1.如图所示是电子受到的洛仑兹力f 与磁场B 、电子运动速度v 三者方向之间关系的示意图，其中正确的是（ ）A. B. C. D.【答案】A【解析】A ．由于电子带负电，由左手定则可知，电子受的洛伦兹力水平向右，故A 正确； B ．由于电子速度方向与磁场平行，所以电子不受洛伦兹力，故B 错误； C ．由于电子带负电，由左手定则可知，电子受的洛伦兹力水平向左，故C 错误； D ．由于电子带负电，由左手定则可知，电子受的洛伦兹力垂直纸面向外，故D 错误。
故选A 。
2.如图所示，平面内有Rt ∆ABC ，其中∠C ＝30︒。
将电荷量为＋4Q 、－Q 的点电荷P 、Q 分别放在Rt ∆ABC 的A 、C 两个顶点上，P 、Q 之间的库仑力大小为F 。
现保持电荷Q 的位置不变，将电荷P 从A 点移到B 点，则P 、Q 之间的库仑力大小为（ ）A.14F B.34F C.43F D. 4F【答案】C【解析】由库仑定律可得24kQ QF AC⋅=电荷P 从A 点移到B 点，P 、Q 之间的库仑力'24Q QF kBC⋅=由三角关系可知cos30BC AC ︒=⋅ 联立解得'43F F = 故选C 。
3.如图所示，三个电阻R 1、R 2、R 3的阻值相同，允许消耗的最大功率分别为10W 、10W 、4W ，则此电路允许消耗的最大功率为（ ）A. 12WB. 15WC. 16WD. 24W【答案】B【解析】由题意知R 1=R 2=R 3=R ，P 1=10W ，P 2=10W ，P 3=4W ，因为R 2与R 3并联，则两端电压相等，所以由公式2U P R=知道R 2与R 3所消耗的功率一样，所以R 2、R 3在电路中允许最大功率只能是4W ，否则会超过R 2的允许功率；把R 2与R 3看成一个并联电阻R′，则电路就是R 1与R′串联，而串联电路所流过的电流一样，由2P I R =知道，R 1与R′所消耗功率之比等于12P R P R ==''，所以R 1上消耗的功率是并联电阻R′上的两倍，如果R 2、R 3的功率都为4W ，则R′的功率就是4W+4W=8W ，则R 1的功率是2×8W=16W ，这样就大于10W ，显然不可以；所以只能是R 1功率为10W ，则R′是R 1的功率一半就是5W ，而R 2与R 3的消耗功率一样,所以R 2与R 3的消耗功率均是R′的一半，为2.5W ，最后计算R 1功率为10W ，则R 2为2.5W ，R 3为2.5W ，所以总功率最大为10W+2.5W+2.5W=15W ，故B 正确，A 、C 、D 错误； 故选B ．4.如图所示，等长的直导线AB 、CD 平行放置，过两导线中点的连线EF 与两导线垂直，O 是EF 的中点。
