很多人说：什么是意境？意境就是“情”“景”交融。

其实这种解释应该是从近代开始的。

XXX在《人间词话》中所使用的“意境”或“境界”，他的解释就是情景交融。

但是在中国传统美学中，情景交融所规定的是“意象”，而不是“意境”。

中国传统美学认为艺术的本体就是意象，任何艺术作品都要创造意象，都应该情景交融，而意境则不是任何艺术作品都具有的。

意境除了有意象的一般规定性之外，还有自己的特殊规定性，意境的内涵大于意象，意境的外延小于意象。

那么意境的特殊规定性是什么呢？唐代XXX有句话：“境生于象外。

”“境”是对于在时间和空间上有限的“象”的突破，只有这种象外之“境”才能体现作为宇宙的本体和生命的“道”。

从审美活动的角度看，所谓“意境”，就是超越具体的有限的物象、事件、场景，进入无限的时间和空间，从而对整个人生、历史、宇宙获得一种哲理性的感受和领悟。

西方古代艺术家，他们给自己提出的任务是要再现一个具体的物象，所以他们，比如古希腊雕塑家追求“美”，就把人体刻画得非常逼真、非常完美。

而中国艺术家不是局限于刻画单个的人体或物体，把这个有限的对象刻画得很逼真、很完美。

相反，他们追求一种“象外之象”、“景外之景”。

中国园林艺术在审美上的最大特点也是有意境。

中国古典园林中的楼、台、亭、阁，它们的审美价值主要不在于这些建筑本身，而是如同XXX《兰亭集序》所说，在于可使人“仰观宇宙之大，俯察品类之盛。

我们生活的世界是一个成心味的世界。

XXX有两句诗说得好：“此中有真意，欲辩已忘言。

”艺术就是要去寻找、发现、体验生活中的这种意味。

成心境的作品和普通的艺术作品在这一点的区别，就在于它不但揭示了生活中某一个具体事物或具体事件的意味，并且超出了具体的事物和事件，从一个角度揭示了整个人生的意味。

AChina is a land of bicycles. At least it was back in 1992 when I traveled the country. Back then everyone seemed to be ridin g a bicycle. Millions of them, all black. Cars were rare. Yet sin ce my arrival in Beijing last year, I've found the opposite is tru e. There are millions of cars. However, people still use their bi cycles to get around. For many, it's the easiest and cheapest way to travel today. Bicycles also come in different colors—silver, green, red, blue, yellow, whatever you want.It's fun watching people biking. They rush quickly through c rossroads, move skillfully through traffic, and ride even on sidewalks(人行道). Bicycles allow people the freedom to move about that car s just can't provide.Eager to be part of this aspect of Chinese culture, I decided to buy a bicycle. Great weather accompanied(陪伴) my great buy. I immediately jumped up on my bicycle seat and started home.My first ride home was orderly(守秩序的). To be safe, I stayed with a “pack” of bikers while cars on t he streets came running swiftly out of nowhere at times. I didn 't want to get hit. So I took the ride carefully. Crossing the stre ets was the biggest problem. It was a lot like crossing a major highway back in the United States. The streets here were wid e, so crossing took time, skill and a little bit of luck.I finally made it home. The feeling on the bicycle was amazi ng. The air hitting my face and going through my hair was wo nderful. I was sitting on top of the world as I passed by places and people. Biking made me feel alive.1. According to the author, why are bicycles still popular in Ch ina today?A. Because they are traditional and safe.B. Because they are convenient and inexpensive.C. Because they are colorful and available.D. Because they are fast and environment friendly.2. The author decided to buy a bicycle because he intended _ ______.A. to ride it for funB. to use it for transportC. to experience local cultureD. to improve his riding skills3.How did the author feel about his street crossing?A. It was boring.B. It was difficult.C. It was lively.D. It was wonderful.4. Which of the following best describes the author's biking ex perience?A. The author enjoyed showing off his biking skills.B. The author was annoyed by the air while riding.C. The author was praised by the other bikers.D. The author took great pleasure in biking.BIt was Mother’s Day morning last year and I was doing my sh opping at our local supermarket with my five-year-old son, Tenyson. As we were leaving, we found that only min utes earlier an elderly woman had fallen over at the entrance and had hit her head on the concrete. Her husband was withher, but there was blood everywhere and the woman was em barrassed and clearly in shock.Walking towards the scene, Tenyson became very upset a bout what had happened to the couple. He said to me, “Mum, it’s not much fun falling over in front of everyone.”At the front of the supermarket, a charity(慈善) group had set up a stand selling cooked sausages and flo wers to raise funds. Tenyson suggested that we should buy th e lady a flower. “It will make her feel better,” he said. I was am azed that he’d come up with this sweet idea. So we went over to the flower seller and asked her if we could buy a flower for the lady to cheer her up. “Just take it,” she replied. “I can’t tak e your money for such a wonderful gesture.”By now paramedics(急救人员) had arrived, and were attending to the injured woman. As we walked up to her, my son became intimidated by all the bl ood and medical equipment. He said he was just too scared t o go up to her.Instead I gave the flower to the woman’s husband and told him, “My son was very upset for your wife and wanted to give her this flower to make her feel better.”At that, the old man started crying and said, “Thank you so much, you have a wonderful son. Happy Mother’s Day to you.”The man then bent down and gave his wife the flower, tellin g her who it was from. Though badly hurt and shaken, the old lady looked up at Tenyson with love in her eyes and gave hima little smile.5.What dose the author intend to tell us?A. One can never be too careful.B. Actions speak louder than words.C. Love begins with a little smile.D. A small act of kindness brings a great joy.6. Which of the following is TRUE according to the passage?A. The elderly woman was knocked down by Tenyson.B. Tenyson’s idea of buying a flower gained his mother’s supp ort.C. Tenyson’s care for the elderly woman puzzled the flower s eller.D. The elderly woman was moved to tears by Tenyson’s gest ure.7. The underlined word “intimidated” in the fourth paragraph p robably means “___________”.A. astonishedB. struckC. frightenedD. excited8. What would be the best title for the passage?A. Flower’s PowerB. Mother’s DayC. An Accidental InjuryD. An Embarrassing Moment CHere's a link to an office rental ad I found online:www.o /10-01. I think it's worth looking at even though the rent is abit high. I know it is a good deal more than we are paying now, but look at the size. It's twice as big as our current office, and I'm sure we can use the space. And it has a kitchen, a bathroom and a reception area just like we have now. Unfortunately it is nowhere near a subway station. That is a convenience I would miss having,but it does have parking,unlike our current office. I'm sure our clients would appreciate that. It would also be good to be in a building with an elevator. I'm really tired of using the stairs. I'd like to see the space as soon as possible. Could you call and make an appointment? Try andget one for tomorrow if you can, because after that I'll be away until next Monday, as you know. Thanks.Paul9. How much would Marilyn and Paul have to pay before movi ng into the advertised office?A. $900.B. $1,750.C. $1,800.D. $3,500.10. What does the advertised office have that the current office doesn't?A. A kitchen.B. A bathroom.C. A parking area.D. A reception area.11. When does Paul want to see the office?A. Monday.B. Tuesday.C. Wednesday.D. Thursday.DStephen William Hawking(1942.1-2018.3), was a theoretical physicist, cosmologist, author and Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge. Having spent his career d ecoding the universe and even experienced weightlessness, he was urging the continuation of space exploration — for hu manity’s sake. The 76-year-old Hawking once said he did not think humans would survive another 1,000 years “without escaping beyond our fragile （脆弱的）planet.”The scientist made the remarks before an audience of doctors , nurses and employees at Cedars-Sinai Medical Center, where he toured a stem cell laboratory t hat’s focused on trying to slow the progression of Lou Gehrig’s disease.Hawking was diagnosed (诊断) with the neurological disorder 55 years ago while studying at Cambridge University. He recalled how he became depres sed and at first didn’t see a point in finishing his PhD. But he c ontinued to devote himself to his studies.“If you understand how the universe operates, you control i t in a way,” he said. Famous for his work on black holes and t he origins of the universe, Hawking was also well-known for bringing abstract physics concepts to the masses t hrough his best-selling books.Hawking survived longer than most people with Lou Gehri g’s disease, also known as amyotrophic lateral sclerosis. ALS attacks nerve cells in the brain and spinal cord(脊髓) that control the muscles. People gradually have more and more trouble breathing and moving as muscles weaken and w aste away. There’s no cure and no way to reverse (倒转) the disease’s progression. Few people with ALS live longe r than a decade.Hawking received around-the-clock care, could only communicate by twitching his cheek, an d relied on a computer mounted to his wheelchair to convey hi s thoughts in a unique robotic monotone.Despite his diagnosis, Hawking remained active. In 2007, he floated like an astronaut on an aircraft that created weightl essness by making parabolic(抛物线) dives. “However difficult life may seem, there is always so mething you can do.” he said.12. Why did Hawking remark that humans will not survive ano ther 1,000 years?A. To warn the earth may not be suitable to live on.B. To make his theory on cosmology widely accepted.C. To show the earth is becoming more and more fragile.D. To persuade human beings to further space exploration.13. What must human beings do if they want to survive accor ding to Hawking?A. Study the universe without stop.B. Escape possible future disasters.C. Realize the way the universe works.D. Protect the environment of the earth.14. What if a person suffers from Lou Gehrig’s disease?A. They will be unable to walk or speak to others.B. They are likely to die within ten years generally.C. They can recover a little bit if they are treated early.D. They are mostly assisted by especially-designed robots15. What do Hawking’s achievements in science lie in?A. His interest in physics.B. His creation of black holes. .C. His research on the universe.D.His strong will against disease.第二节（共5小题；每小题3分，共15分）根据短文内容，从短文后的七个选项中选出能填入空白处的最佳选项，选项中有两项为多余选项，并将答案写在答题卡上。

2017-2018学年度高一期末考试英语试题（含答案）第一部分听力理解（略）第二部分阅读理解（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。

AChocolate is good for your heart, skin and brain. Usually, people think that chocolate is bad for their health. They describe chocolate as “something to die for” or say “death by chocolate”. Now they should bite their tongues! Evidence is showing that some kinds of chocolate are actually good for you in the following ways:A happier heartScientists at Harvard University recently examined 136 studies on cocoa—the main ingredient in chocolate and found that it does seem to strengthen the heart．Studies have shown heart benefits from increased blood flow. These benefits are the result of coca’s chemicals, which seem to prevent both cell damage and inflammation (炎症)．Better blood pressureIf yours is high, chocolate may help. Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3.5 ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly.Muscle magicChocolate milk may help you recover after a hard workout (锻炼). In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks.Better for your skinGerman researchers gave 24 women a half-cup of special cocoa every day. After three months, the women’s skin was moister(滑润的) and smoother. The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance．Brain gainsIt sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving by increasing blood flow to the brain．21. What’s the meaning of “bite their tongues” in the first paragraph?A. Stop talking.B. Speak up.C. Think of it.D. Listen to it.22. What can’t we get from chocolate according to the text?A. A healthy heart.B. Smooth skin.C. A good mood.D. A beautiful figure.23. What’s the meaning of the underlined sentence in the fourth paragraph?A. Sports drinks are better than chocolate milk.B. Sports drinks can make people feel tired easily.C. Drinking milk can keep you energetic at work.D. We should drink chocolate milk between times when we work hard.24. The conclusion that chocolate may help lower blood pressure was made by ______.A. scientists at Harvard UniversityB. Jeffrey Blumberg from Tufts UniversityC. scientists at Indiana UniversityD. German researchersBBody language is one of the most powerful means of communication, often even more powerful than spoken language. It is said that our body movements communicate about 50 percent of what we really mean while words only express 7 percent. So, while your mouth is closed, your body is just saying.Arms. How you hold your arms shows how open and receptive you are to people you meet. If you keep your arms to the sides of your body or behind your back, this suggests you are not afraid of taking on whatever comes your way. Outgoing people generally use their arms with big movements, while quieter people keep them close to their bodies. If someone upsets you, just cross your arms to show you’re unhappy!Head. When you want to appear confident, keep your head level. If you are a monitor in class,you can also take on this position when you want your words to be taken seriously. However, to be friendly in listening or speaking, you must move your head a little.Legs. Your legs tend to move around a lot more than normal when you are nervous or telling lies. If you are at interviews, try to keep them still!Posture (姿势). A good posture makes you feel better about yourself. If you are feeling down, you normally don’t sit straight, with your shoulders inwards. This makes breathing more difficult, which can make you feel nervous or uncomfortable.Mouth. When you are thinking, you often purse(噘嘴) your lips. You might also use this position to hold back an angry comment you don’t wish to show. However, it will probably still be noticed, and people will know you’re not pleased.Face. When you lie, you might put on a false face. But that expression would crack briefly, allowing displays of true emotions such as happiness, sadness, disgust (厌恶) and fear to come through.25. When someone is keeping his arms behind his back, he tries to tell you thatA. he is angry.B. he is outgoing.C. he is cool.D. he is not afraid.26. If you want to appear confident, you shouldA. cross your arms.B. move your head a little.C. keep your head level.D. move your arms a lot.27. Which of the following movements shows someone is nervous?A. Not sitting straight with the shoulders inwards.B. Moving around a lot more than normal.C. Keeping the arms to the sides of the body.D. Having the lips pursed to hold back an angry comment.28. What can we infer from the passage?A. Body language can express more meanings than words do in communication.B. It’s not polite to use body language in formal communication.C. Different people in different countries must have the same understanding of the same bodymovement.D. We cannot communicate with others without words.COn one of her trips to New York several years ago,Eudora Welty decided to take a couple of New York friends out to dinner.They settled in at a comfortable East Side cafe and within minutes, another customer was approaching their table.“Hey,aren't you from Mississippi?”the elegant,white-haired writer remembered being asked by the stranger, “I’m from Mississippi too.”Without a second thought,the woman joined the Welty party.When her dinner partner showed up, she also pulled up a chair.“They began telling me all the news of Mississippi,”Welty said.“I didn't know what my New York friends were thinking.”Taxis on a rainy New York night are rarer than sunshine.By the time the group got up to leave,it was pouring outside.Welty’s new friends immediately sent a waiter to find a cab.Heading back downtown toward her hotel,her big-city friends were amazed at the turn of events that had changed their Big Apple dinner into a Mississippi state reunion（团聚）.“My friends said:‘Now we believe your stories,’”Welty added.“And I said:‘Now you know.These are the people that make me write them.’”Sitting on a sofa in her room,Welty,a slim figure in a simple gray dress,looked pleased with this explanation.“I don’t make them up,”she said of the characters in her fiction these last 50 or so years.“I don’t have to.”Beauticians,bartenders,piano players and people with purple hats,Welty’s people come from afternoons spent visiting with old friends,from walks through the streets of her nativeMiss.Jackson,form conversations overheard on a bus.It annoys Welty that,at 78,her left ear has now given out.Sometimes,sitting on a bus or a train,she hears only a fragment（片段）of a particularly interesting story.29. What happened when Welty was with her friends at the cafe?A. Two strangers joined her.B. Her childhood friends came in.C. A heavy rain ruined the dinner.D. Some people held a party there.30. The underlined word "them" in Paragraph 6 refers to Welty's .A. readersB. PartiesC. friendsD. stories31. What can we learn about the characters in Welty's fiction?A. They live in big cities.B. They are mostly women.C. They come from real life.D. They are pleasure seekers.DA girl with blue eyes is a blue-eyed girl. A man with long legs is a long-legged man. A woman with white hair is a white-haired woman. Children who have good looks are good-looking children. What do you do when you want to buy clothes? You go to a shop. If you can find clothes that are the right size for you, and if they are ready to wear, you will probably buy them. They are called ready-made clothes. If you can not find clothes that are the right size, you will go to a tailor’s shop. A tailor is a man who makes clothes. He will measure you carefully and will then make clothes for you. Such clothes are called tailor-made clothes.What do we call a man who is dressed badly? We call him a badly-dressed man. A woman who is dressed well is called a well-dressed woman.What do you wear when it rains heavily? You wear a coat that will keep the rain out. Such a coat is called a raincoat. It is made of waterproof cloth-cloth that does not let water pass through. We have a lot of rain in England. If you come to England, bring a raincoat and an umbrella. You will find them useful.If the floor, walls and ceiling of a room are made so that sound cannot pass through the wall, we say that the room is sound-proof. There are sound-proof rooms in all broadcasting stations.32. The clothes which you buy from the supermarket are called clothes.A. tailor-madeB. ready-madeC. hand-madeD. mass production33. If you come to England, bring both a raincoat and an umbrella because .A. there is a lot of rain in EnglandB. there are few umbrellas in the countryC. gentlemen usually carry umbrellas with them in EnglandD. walking with an umbrella in hand is popular in England34. On back of a watch we can often see the word “water-proof”.
