第一卷阅读题一、现代文阅读〔35分〕〔一〕论述类文本阅读〔此题共3小题，9分〕阅读下面的文字，完成1～3题。
先秦儒家已形成比拟立体、丰富的生态伦理思想。
这种思想首先表达为“乐〞。
孔子非常擅长在观察自然现象时对自身社会经历进展审视和升华，自然之道和其处世之道在某个适宜的时间节点产生共鸣，从而引发孔子深层的思考，其生态情怀也在类似的体悟中逐渐浓厚。
认知自然、体验自然、进而体悟人生哲理，让孔子得出“知者乐水，仁者乐山〞这样的结论。
由“乐〞而生“畏〞。
孔子说：“天何言哉。
四时行焉，百物生焉。
天何言哉！〞在孔子看来，四季的轮回、万物的生长都有其运行轨迹和规律，这种力量非人力所能干预，孔子对自然的敬畏之情也在这种感慨中毕现。
荀子那么认为：“天行有常，不为尧存，不为桀亡。
〞既然这种“常〞的力量如此强大，非人力所能改变，聪明的做法就是顺应这种力量并对之合理利用，即荀子所讲的“制天命而用之〞。
那么，该如何“制〞呢？荀子较为强调见微知著、因循借力、顺时守天、因地制宜。
这种总结比起孔子体验式思维多了些理性，已试图对联系自然与人类社会的“道〞进展理性阐释和总结。
在此根底上，“推人及物〞的思想就产生了。
“人皆有不忍人之心〞是孟子生态道德的根底，“不忍心〞推广于自然万物就成了推人及物的生态道德。
如果说“老吾老以及人之老，幼吾幼以及人之幼……故推恩足以保四海，不推恩无以保妻子〞是简单适用于人类社会的推恩思维，是简单的换位思考、推己及人，那么，孟子的“亲亲而仁民，仁民而爱物〞那么已拓展为推人及物了。

AThere are an unbelievable number of reasons to go to Greece; just like there are an unbelievable number of things to do once a traveler arrives there. Here is a look at just some of the great historical things to see when on holiday in Athens, Greece.AgoraAgora lies in ruins now, but during its glory days it was a lively and active open marketplace where Greeks came to buy, sell, and exchange their goods and services. Agora has ties to common people of ancient Greece. Guided tours are available and there is also a small museum with many artifacts from this area on display.ParthenonOne of the most famous landmarks in Athens is the legendary Parthenon. This building is still today admired by architects who are appreciative of the decorative design, as well as the engineering involved in its construction. Those interested in history will be impressed beyond belief with theopportunity to see this historic structure up close and personal.Temple of Olympian ZeusOne of the most impressive monuments to see up close is the Temple of Olympian Zeus. Many people see this monument from far away, or even from the window of a taxi, and never stop for a first hand look themselves. This is a huge mistake as the size of it cannot truly be appreciated without visiting it up close.Odeum of Herodes AtticusBuilt into the hillside and providing a nice view of Athens is the Odeum of Herodes Atticus. This theater was constructed in the second century and was an important gathering place for both the upper and lower classes. It holds a little over 5,000 people, is located just below the Acropolis, and is still used for performances to this day.21. What did the ancient Greeks do in Agora?A. They toured around.B. They did business.C. They visited museums.D. They prayed for blessings.22. Who will show the most interest in Parthenon?A. Building designers.B. Electrical engineers.C. Ordinary visitors.D. Religious people.23. How can visitors fully appreciate the Temple of Olympian Zeus?A. By looking in the distance.B. By visiting up close.C. By taking a bird’s-eye view.D. By seeing through a taxi window.24. In what way is Odeum of Herodes Atticus different from the others?A. It has great historical value.B. It has ties to common people.C. It still serves its original purpose.D. It is famous for its architecture.BWomen make better drivers than men for many reasons. Why is that, do you suppose? Wouldn’t you think t hat competing at who has better driving abilities is pointless? If you ask me, I’d like to say, men know that women are better drivers but do not have the courage to admit the truth—women are queens of the road.Unlike men, women stop for directions when they have no idea as to where they are going. We don’t drive around for hours pointlessly wasting a tank of gas only to find ourselves heading in the wrong direction. Have you ever in a car with a man who is lost? He tells you to shut up when you begin to open your mouth. And every five minutes or so he takes a tum going forty-five miles per hour only to find out he’s made another wrong turn.Speeding is what men do best on the road. Traffic is not a race. There is a reason why men get more speeding tickets than women. Not because we trick to get out of tickets but only because we don’t get pulled over as frequently. We don’t speed. We have more intelligence than senselessly to put our own lives as well as the lives of others in danger.My largest issue with male drivers is how a majority of them drive with one hand on the wheel and the other hand doing only God knows what. The seat is backed as far as possible, and they’re totally lost into loud music beyond a necessary level. You don’t ever see women driving like that.I feel that the above evidence more than proves my points that women are not only better drivers but also safer drivers than men. We women rule the road. Oh, and men, , if you want to continue criticizing women for being bad drivers, bring it on. We know you lack confidence, or else you wouldn’t be wasting your valuable time making jokes about the ones you may choose to spend the rest of your days with.25. If a woman driver feels lost, she will .A. stop the car and ask people for helpB. tell the man next to her to shut upC. take the wrong turns at a high speedD. drive aimlessly for hours without stopping26. In Paragraph 3, the writer tries to tell us that .A. women always have more responsibility for livesB. women often play tricks on the police in chargeC. men are more confident and more skillful in drivingD. men usually have to be pulled over to the roadsides27. Which of the following about men drivers worries the writer most?A. Making jokes about women.B. Not paying full attention.C. Not stopping for directions.D. Getting more speeding tickets.CChildren spend more time messaging each other on phones and websites than talking in Person, a survey has revealed. Text messages and social networking sites have become the common mode of youngsters aged 8 to 14.A survey of modem childhood found that many youngsters are conscious that they are spending too much time on their computers and enjoy themselves the most when playing outside. But the lure of electronic products pr oves too strong for a quarter, while a fifth say their parents don’t like them playing outside because they are worried about strangers and injuries.The “iGeneration report” suggested that youngsters are increasingly health-conscious and skeptical (特怀疑态度的) of commercialization, including gender-based labelling on toys and pop videos released by singers. More than half of those questioned care about eating healthily and one in 10 lectures their own parents about the food they are eating or buying, 42 percent of those questioned own a smart phone, with 36 percent admitting spending more time communicating with friends via instant messaging, such as texts or networking websites, than talking in person. Only one child in 100 said that being happy, having a loving family and being clever were taken as the most crucial (决定性的) elements in their lives.Cary Cooper, the professor of organizational psychology and health at Lancaster University, said social media were contributing to youngsters becoming more independent. They had a sense of individuality due to exposure to a range of media.The survey follows major state backed research which found that youngsters are turning their back on drink, drugs and smoking. It found a dramatic drop in the number of secondary school students trying and regularly using drugs, alcohol and tobacco. Some analysts said that thanks to therise of social media, millions of teenagers are spending their time at home in their rooms rather than out on the streets.28. Why can’t 25 percent of the children get away from electronic products?A. They are not allowed to hang out long.B. They are protected from strangers and injuries.C. They enjoy themselves most when playing outside.D. They can’t resist the temptation of the products.29. The survey of modem childhood found that many youngsters .A. are fans of the pop videos released by singersB. message each other more rather than chat in personC. are doubtful about possessing the latest smart phonesD. pay no attention to their lifestyle nowadays30. The attitude of Cary Cooper towards social media is .A. objectiveB. negativeC. supportiveD. unclear31. The last paragraph is written to show .A. the benefits of social mediaB. the drop of taking drugs in youngstersC. the exposure to a range of mediaD. youngsters are becoming more consciousDThe city of Armada opened its arms to a new business on Huntington Drive at First Street. The store, called Turtle Dove, is a pet shop specialising in two kinds of animals. The owners are two brothers, Bill and Bob Pidgin. They moved here from Northern California, where they owned an ant farm store called Animal House. That store was such a success that after five years they sold it for a big profit.They took it easy for a c ouple of years, travelling throughout the states. “We visited almost every zoo in the country, partly because we love animals and partly because we were looking forinspiration for our next business.” said Bill. They finally decided on turtles and doves. “They're easy to feed and care for, and both animals live a long time,” said Bob.The store will be open from 9:00 am to 9:00 pm Wednesdays through Saturdays. “We think those are hours that our customers will find very convenient. Plus, the three days' off gives us a chance to go into the woods and find more critters. We never buy our own animals, but we always try to collect them from the wild. That way we can pass on huge savings to our customers. And, of course, by removing these animals from their natural habitats, we protect them from being eaten by their natural enemies. So our customers are happy, our animals are happy, and we’re happy. It's a win-win situation for all of us.” said Bill and Bob.32. Why did Bill and Bob Pidgin visit many zoos in the states?A. To gain experience in raising animals.B. To get some ideas for their new business.C. To call on the public to protect animals.D. To find out which animals are in danger.33. What does the underlined word “critters” in the last paragraph refer t o?A. Customers.B. Businesses.C. Animals.D. Foods.34. What can we infer from the last paragraph?A. Turtle Dove is very popular with customers.B. Turtle Dove sells dangerous animals as well.C. Bill and Bob Pidgin like living in the woods.D. Bill and Bob Pidgin are totally free at weekends.35. What would be the best title for the passage?A. Ways Found to Make Big Profits.B. Brothers Help Protect Wild Animals.C. New Ideas to Better Serve Customers.D. City Welcomes New Store and Its Owners.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。

第Ⅰ卷阅读题一、现代文阅读（35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。
先秦儒家已形成比较立体、丰富的生态伦理思想。
这种思想首先体现为“乐”。
孔子非常擅长在观察自然现象时对自身社会经验进行审视和升华，自然之道和其处世之道在某个合适的时间节点产生共鸣，从而引发孔子深层的思考，其生态情怀也在类似的体悟中逐渐浓厚。
认知自然、体验自然、进而体悟人生哲理，让孔子得出“知者乐水，仁者乐山”这样的结论。
由“乐”而生“畏”。
孔子说：“天何言哉。
四时行焉，百物生焉。
天何言哉！”在孔子看来，四季的轮回、万物的生长都有其运行轨迹和规律，这种力量非人力所能干涉，孔子对自然的敬畏之情也在这种感慨中毕现。
荀子则认为：“天行有常，不为尧存，不为桀亡。
”既然这种“常”的力量如此强大，非人力所能改变，聪明的做法就是顺应这种力量并对之合理利用，即荀子所讲的“制天命而用之”。
那么，该如何“制”呢？荀子较为强调见微知著、因循借力、顺时守天、因地制宜。
这种总结比起孔子体验式思维多了些理性，已试图对联系自然与人类社会的“道”进行理性阐释和总结。
在此基础上，“推人及物”的思想就产生了。
“人皆有不忍人之心”是孟子生态道德的基础，“不忍心”推广于自然万物就成了推人及物的生态道德。
如果说“老吾老以及人之老，幼吾幼以及人之幼……故推恩足以保四海，不推恩无以保妻子”是简单适用于人类社会的推恩思维，是简单的换位思考、推己及人，那么，孟子的“亲亲而仁民，仁民而爱物”则已拓展为推人及物了。

independence.However, setting goals doesn't come naturally to your child, so helping him to learn the process should probably be one of your goals.Explain the word “goal”．Your child may know what a goal is when it comes to soccer, but he may not understand what it means in everyday life.__1__Listen to your child.Ideally, you want your child to be able to decide for himself what his goals are.__2__ Let him talk about what he thinks he does well and what he thinks needs to improve.If he's stuck, you can provide some examples of your own personal goals.Help keep goals achievable.Don't throw cold water on your child.__3__ For example, if your child wants to be a champion swimmer, but can't swim an entire lap of the pool yet, you can suggesthe start by making that his first goal.__4__ Help your child write down his goals in an easy-to-follow form.Being able to see and check off the steps on the way to his goal is the key in keeping him motivated.A really simple way is to have your child draw a ladder on a piece of paper, writing his goal at the top and each step to that goal on the rungs (梯级)．__5__A．Change goals every so often.B．Make a visual goal reminder.C．Don't always tell him what you think.D．He's climbing to the top as he gets closer to his goal.E．You can take sports as an example to help explain it to him.F．Once he has set up a goal, he may find it very difficult to achieve it.G．When a goal is beyond his reach, help him break it down into smaller pieces.一、单句语法填空1.instantly2.assisting3.be required4.Surprised 5．imitation6.be located7.to fasten8.where
