AYou can either travel or read,but either your body or soul must be on the way.The popular saying has inspired many people to read or go sightseeing.Traveling just like reading,is a refreshing journey from the busy world.Books,brain food,can keep you company on your travel.On the Road,1957,by Jack KerouacThe book is a globally popular spiritual guide book about youth.The main character in the book drives across the US continent with several young people and finally reaches Mexico.After the exhausting and exciting trip,the characters in the book begin to realize the meaning of life.The book can be a good partner with you to explore the United States.Life Is Elsewhere,1975,by Milan KunderaJean­Jacques Rousseau once said,“Man is born free,and everywhere he is in chains.”The book tells a young artist’s romantic but miserable life,about how he reads,dreams,and has a relationship.Experience the artist’s passionate life in the book during a trip to Central Europe.The book invites you to deeply reflect on your current life.The Stories of Sahara,1967,by SanmaoThe book narrates the author’s simple but adventurous life in the Sahara Desert,which seems a desolate and dull place.The fancy natural scenery and life there,along with the author’s romantic and intensive emotion,will inspire you to explore the mysterious land.Reading the book is like participating in a dialogue with the author,who is sincere and humorous.Lotus,2006,by AnnbabyThis novel set in Tibet,tells three people’s stories,each with their unique characteristics.Itreveals modern people’s emotions and inner life,their confusion about love,and exploration of Buddhism.The book is a good partner to bring you to the sacred land Tibet.21.Which book is about the exploration of life value through a journey?A.On the Road.B.Life Is Else w here.C.The Stories of Sahara.D.Lotus.22.Whose book could be the most suitable for your trip to Germany?A.Jack Kerouac’s.B.Sanmao’s.C.Annbaby’s.D.Milan Kundera’s.23.What can we learn from the text?A.Lotus is a religious book exploring Tibetan Buddhist culture.B.On the Road advises a classic route for driving across the US.C.The Stories of Sahara records its author’s own life in the desert.D.Life Is Else w here demonstrates Jean­Jacques Rousseau’s own life.BIt was a morning in January.The jet stream(急流)had dipped down,causing the Arctic cold to reach the mountains of my home.It was only2degrees outside,but the cold wind made it feel like it was15below zero.Still,I was kneeling in the snow alongside my house trying to open a tiny door,so I could get in.I had forgotten to leave my water dripping the night before and now my water pipes were frozen and my faucets(水龙头)were dry.The wind cut into me like a knife while I struggled to get two electric heaters in place around the section of frozen pipes.The waterlines were buried except for a small piece that connected up to my house.I put a heater on each side of it,ran the extension cords(软线)into my house and plugged them in.Both heaters roared to life and started blowing hot air on the frozen water pipes.My fingers had already started to go numb,so I stayed inside to wait.I could only hope that this bit of warmth could get my water flowing again.Finally,after twenty minutes,the water started flowing through my faucets again.I went back outside into the bitter cold and gathered my heaters up.I looked at the weak January sun shining on the frozen snow and smiled.Then I sent a joy filled with“Thank you”heavenward and returned inside to make myself a hot breakfast.Sometimes the coldness of this life can get to us as well.It can make our hearts feel icy and frozen.It can keep our kindness and love from flowing out to others.Sometimes,though,all we need is a bit of warmth to get us going again.It can be a simple smile,a kind word,a heart­felt hug,a morning sunrise,a bird’s song or any gentle reminder of just how much God loves us.Let us all be grateful for those bits of warmth that get us going again.And let us all try to be that bit of warmth for others every chance we get.24.What was the direct reason why the water pipes were frozen?A.The jet stream.B.The low temperature.C.The cold wind.D.The author’s own carelessness.25.Which of the following can replace the underlined phrase“roared to life”in Paragraph2? A.Began functioning smoothly.B.Worked inappropriately.C.Broke down suddenly.D.Screamed out loudly.26.What did the author think of his work?A.Embarrassed.B.Satisfied.C.Mad with joy.D.Cautiously optimistic.27.What is the last paragraph mainly centered on?A.The coldness of life has a negative effect on our life quality.B.We meet with the coldness of life unavoidably and unwillingly.C.We should be thankful for bits of warmth of life.D.We should seize every chance to receive warmth of life from others.CHistory of amusement parks takes us back to the bar­periodic fairs,like the Bartholomew Fair which started in England.These can be considered a parent for the modern amusement park.Opening in the Elizabethan period,the fair had developed as a center of amusement with entertainment with fun,food,games,and many other attractions.The beer festival held in Munich,Germany which started in1810and the county and state fairs in the US,also played a part in the brief history of amusement parks.Unlike the Bartholomew Fair,these annual events were usually held during an important time when crops were ripe,which deserved to be marked.Amusement parks are also known to have grown out of the pleasure gardens that became very popular at the start of the Industrial Revolution.These were the zones where one could shun the dull urban life for a short while.We can find the oldest and still­surviving amusement park in the world:Bakken in Denmark,which opened in1583.These parks consisted of fireworks displays,rides and the modern railroad to accommodate the growing expectations from their customers.Another turning point in the history of amusement parks was the world’s fairs which began in1851.The Crystal Palace in London,England was a landmark and celebrated the industrial achievements of the world.These were seen as symbols of economic and industrial success.In the last decade of the19th century,the electric trolley lines became extremely popular.Mechanicalamusements,dance halls,sports fields,and restaurants were included as regular entertainments,as the history of amusement parks reflects.The golden age in the brief history of amusement parks didn’t appear until people especially Americans spent less time on work and got a steady rise in their personal income.A number of amusement parks including the kiddie park were set up outside major cities and in the countryside,to make full use of this new economic opportunity.The original Kiddie Park is located in San Antonio,Texas and is still in operation today.28.What was the purpose of the early Munich beer festival?A.To celebrate harvest together.B.To show local attractions.C.To create a stable agricultural market.D.To found a center of amusement.29.What does the underlined word“shun”in Paragraph2mean? A.Experience.B.Complain.C.Tolerate.D.Avoid.30.What made the amusement parks fully developed?A.The Industrial Revolution.B.Advances in technology.C.More time and money for fun.D.Economic and industrial success.31.How does the writer mainly develop the text?A.By comparing amusement parks.B.By providing examples.C.By describing historical events.D.By commenting on events.DPositive thinking is a significant element of happiness.In order to become a positive thinker,determination and consistency are important.The first thing to know about positive thinking is that everyone can do it.With certain cognitive(认知的)and behavioral changes,we can all become positive thinkers.Another important factor is that being a positive thinker does not mean you become numb to anything that is not working properly in your life or is negative—it just means that you approach life and face challenges with a healthier outlook.Instead of selectively attending to negative events,focus on the positive ones.Then pay attention to the delayed consequences of your behavior rather than the immediate ones.For example,if a job is not going like you want,focus on the fact that you have a job and how you cantake your time to make the situation better.Challenge any internal attributions and see if you compare your behavior to standards that are excessively rigid and perfectionistic.If so,change these and be reasonable with your comparisons.For example,if you constantly compare your weaknesses with other people’s strengths,then switch this and compare yourself with those who are doing poorer than you as well.Overall,people who focus more on their strengths than their weaknesses but at the same time are aware of their weaknesses have a healthier self­evaluation result.When faced with too much fear about a situation,imagine the worst case and visualize a solution for it;then let go of fear.This way,you will be prepared for anything and your fear will not block you from being open and creative to different solutions.For example,if you are constantly worried about losing your job up to a point where it is creating a lot of anxiety and fear and is affecting your performance and your happiness negatively,then think of losing your job,visualize how you will handle it,find solutions in your mind and then let go of the thought and the fear attached to it.So positive thinkers are better problem­solvers and have better interactions.In addition to that,people who are positive thinkers are happier and more satisfied with their life.32.Why is positive thinking a significant element of happiness?A.It means that one is blind to the troubles and difficulties that exist.B.It means that one constantly compares everything with other people’s.C.It means that one is strong in mind and has nothing to be afraid of.D.It means that one approaches life and faces challenges more healthily.33.What does the text suggest about the job you don’t like?A.Quitting it and finding a better one.B.Keeping and trying to make it better.C.Being negative and numb to it.D.Challenging yourself with a new outlook.34.What does the author intend to tell us in Paragraph4?A.Be prepared for the worst and let go of fear.B.Being constantly worried will lose your job.C.Fear will prevent you being open and creative.D.There is nothing to fear if well prepared.35.What can be a suitable title for the text?A.How to Focus on the Positive EventsB.How to Be a Positive ThinkerC.What to Do When Faced with FearD.What to Know of Self­evaluation第二节(共5小题;每小题2.5分,满分12.5分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。
